Wang, Yan. "Innovation systems and regional governance for the development of low carbon building technologies in Wales : a 'functions approach'." Thesis, Cardiff University, 2015. http://orca.cf.ac.uk/76869/.
Full textAbstract:
Having arguably led the world in the transition to a high carbon economy, much of Wales today is economically and socially deprived. Even so, a devolved Welsh Government has set ambitious targets to reduce carbon emissions in the devolved areas, while creating employment and economic opportunities, reducing fuel poverty, thereby helping to solve Wales’ entrenched social and economic problems. A low carbon transition in the built environment is critical to achieve such targets. This PhD study aims to provide theoretically informed and empirically grounded insights into the development of low carbon building technologies in Wales through examining how the functions of the innovation systems of two selected emerging technologies i.e. ‘Welsh grown timber for construction’ (WTC) and ‘building integrated solar energy systems’ (BISE) have been fulfilled. Having first established a bespoke analytical framework, the functional patterns of the two technological innovation systems (TIS) are documented, assessed and compared. The study further explores how the functional analyses may offer a bottom-up perspective on the policy implications for regional governance in Wales, which might alter the functional patterns, and improve the innovation capability of relevant Welsh organisations. The functional analyses of the WTC and BISE TIS shows that, although both TISs have reached their formative phases in Wales, there is no guarantee that either system will eventually move onto the phase of market diffusion, due to the inherent system weaknesses and uncertainties likely arising in technology, policy-making, and market. Whereas regional governance in Wales can introduce policy interventions, they matter only when breakouts from certain forms of institutional ‘path-dependence’ are induced. In this respect, the thesis concludes by discussing four streams of policy-thinking that may instigate different pathways in Wales, namely: technology foresight; the regulation-induced innovation hypothesis; demand-oriented policy measures; and, support for small business innovations through, e.g. R&D consortia.

Full textAbstract:
Building a thriving information economy is a goal for many developing countries. This research helps identify the factors (inhibitors and motivators) that can be used to leverage the Information and Communication Technology (ICT) sector in a developing country to build a sustainable information economy that benefits other sectors of the economy. This is done by studying the current literature on this topic and then synthesizing the theoretical models to create a unified decision framework to help developing countries set their path to building a sustainable information economy.
Drawing on past literature and extant theory, a novel ICT4D decision framework is built that provides a three-dimensional view based on 1) the ICT value chain, 2) key factors (e.g. infrastructure, policies, markets), and 3) stakeholders (e.g. industry, government, academia). This decision framework is then used to study the case of Palestine, where secondary and primary data are used to compare the critical success factors for Palestine with the general framework. This synthesized framework and critical success factors superset is expected to advance the field’s understanding of how both controllable and non-controllable country characteristics contribute to or inhibit the growth and development of an ICT sector in developing countries. In addition, the framework and identified success factors help in setting a future path for development.
Results from both secondary data sources demonstrate the usability of the framework to analyze the current setting of the ICT sector, in addition, to help investigate a range of possible opportunities for action to reach a higher level of ICT success. Then, via a targeted set of interviews with academic, industrial, and governmental sources who are experts in the Palestinian ICT arena, an exploratory study was performed that focused on key critical success factors for future development of the ICT economy. Controllable factors that have the potential for sustainable action were identified.
In the case of Palestine, it appears that despite having many challenges that are out of control, there seem to be many opportunities for change specifically in government and educational policies that can help the ICT sector in specific, and the Palestinian economy in general reach its real potential. Given the current political situation in Palestine, it was found that there is a great potential in creating new software products for export. The challenges in this particular area in the case of Palestine lies in the lack of adequate business skills to research the global market and to market products and services that can be offered by the Palestinian ICT sector.
The findings should also help stakeholders see if the challenges to developing an ICT sector in Palestine are the same as those for any developing country, and where they are truly unique. The outcomes of this research have the potential to frame and inform economic development decisions that could define the future of the Palestinian state.

Stenström, Johanna, and Sandra Hagman. "Robotic Process Automation (RPA) i bygglovsprocessen: En studie om effektivisering och dess påverkan på arbetstillfällen." Thesis, Jönköping University, JTH, Byggnadsteknik och belysningsvetenskap, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-54049.
Full textAbstract:
Syfte: Den rådande digitaliseringen av samhällsbyggandet leder till möjlighet att automatisera och effektivisera processer inom samhällsbyggandet. Att automatisera delar av bygglovsprocessen med hjälp av Robotic Process Automation (RPA) är möjligt. En sådan implementering skulle kunna leda till effektivare processer, men kanske även andra effekter, negativa som positiva. Några av Sveriges kommuner har redan implementerat RPA i bygglovsprocessen och andra står i begrepp att göra det inom kort. Därför är det av hög relevans att utreda hur mycket RPA kan effektivisera bygglovsprocessen samt undersöka hur automatisering påverkar arbetet för personal på bygglovsenheter. Syftet med denna studie är, därför, att undersöka i vilken utsträckning bygglovsprocessen kan effektiviseras med hjälp av RPA. Vidare önskar studien utreda hur en sådan implementering kan påverka arbetsuppgifter och arbetstillfällen för bygglovshandläggare och administratörer på bygglovsenheter i Sverige. Metod: Denna studie utförs som en survey. För att uppnå studiens syfte och mål har två olika datainsamlingstekniker valts, där primärdata insamlas genom intervjuer och sekundärdata via en dokumentstudie. Studien är således i huvudsak av kvalitativ karaktär, men kompletteras med kvantitativ empiri för att kunna styrka slutsatser. Resultat: I rapporten framkommer det att bygglovsprocessen effektiviseras med hjälp av RPA. Genom att automatisera moment i processen, beräknas 141,5 timmar/månad sparas in på tidigare manuellt utförda arbeten. Tiden som sparas in läggs istället på uppgifter som anses relevanta och mer kunskapskrävande. Detta i sin tur leder till en förändring av arbetsuppgifter för de anställda på bygglovsenheten och lyfts som en positiv aspekt. Vidare visar studien att bygglovshandläggares arbetstillfällen inte har påverkats på grund av RPA samt ger inga anvisningar på att deras arbeten i framtiden kommer hotas. De som påverkas mest av implementeringen är administratörer, då det främst är administrativa uppgifter som kan ersättas av RPA. Studien ger en viss indikation på att administrativa tjänster och behovet av administratörer på bygglovsenheter kan komma att minska, som en följd av automatisering. Konsekvenser: Genom att implementera RPA i bygglovsprocessen uppnås inte bara en effektivisering av processen. Andra fördelar som nöjdare medarbetare och högre kvalitét på besluten är också effekter av automatisering. Nöjdare medarbetare kan, i förlängningen, leda till färre antal uppsägningar och följaktligen en förhöjd kompetensnivå på bygglovsenheten. Högre kvalitét på beslut leder till ett ökat förtroende för bygglovsenheter i Sverige. Vidare kan även RPA bidra till en mer enhetlig bygglovsprocess kommuner emellan, då uppsatta funktioner och regler, samt information kan delges mellan kommunerna. Begränsningar: Då studien utförts som ett examensarbete har begräsningar funnits i form av antal ord som studien får omfatta. Utöver det har studien undersökt tre av Sveriges kommuner som arbetat med RPA i minst ett år. Om fler kommuner undersökts, skulle studiens validitet kunnat öka.Purpose: The current digitalization of community building leads to the opportunity to automate and streamline processes in community building. Automating parts of the building permit process using Robotic Process Automation (RPA) is possible. Such implementation could lead to more efficient processes, but perhaps also other effects, negative and positive. Some of Sweden's municipalities have already implemented RPA in the building permit process and others are about to do so shortly. Therefore, it is of high relevance to investigate how much RPA can make the building permit process more efficient and investigate how automation affects the amount of work for employees at building permit units. The purpose of this study is to investigate the extent to which the building permit process can be streamlined with the help of RPA. Furthermore, the study wishes to investigate how such an implementation can affect the tasks and jobs of caseworkers and administrators at building permit units in Sweden. Method: This study is carried out as a survey. In order to achieve the purpose and objectives of the study, two different data collection techniques have been selected, where primary data is collected through interviews and secondary data via a document study. The study is thus mainly of a qualitative nature but is supplemented with quantitative empirical evidence in order to substantiate conclusions. Findings: The report shows that the building permit process is made more efficient with the help of RPA. By automating steps in the process, it is estimated that 141.5 hours/month is saved on previously manually performed work. The time saved is instead mainly spent on tasks that are considered relevant and more knowledge-intensive. This in turn leads to a change in tasks for the employees at the building permit unit, and is highlighted as a positive aspect. Furthermore, the study shows that jobs of building permit caseworkers have not been affected due to RPA and does not provide any indications that their work will be threatened in the future. Those most affected by the implementation are administrators, as it is mainly administrative tasks that can be replaced by RPA. The study provides some indication that administrative services and the need for administrators in building permit units may decrease, as a result of automation. Implications: By implementing RPA in the building permit process, not only is the process streamlined. Other benefits such as more satisfied employees and higher quality of decisions are also effects of automation. Satisfied employees can lead to fewer redundancies and consequently an increased level of competence at the building permit unit in the long run. Higher quality of decisions leads to increased trust in building permit units in Sweden. Furthermore, RPA can also contribute to a more unitary building permit process between municipalities, as established functions and rules, as well as information can be shared between the municipalities. Limitations: Since the study was carried out as a bachelor thesis, there were restrictions of the number of words that the study may include. In addition, the study examined three of Sweden's municipalities that worked with RPA for at least one year. If more municipalities were examined, the validity of the study could increase.

Lennartsson, Martin. "Modularity in industrialised timber housing : a lean approach to develop building service systems." Licentiate thesis, Luleå tekniska universitet, Byggkonstruktion och -produktion, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:ltu:diva-16793.
Full textAbstract:
Modularity has been applied in various disciplines, e.g. manufacturing, computer, cognitive science and education. General advantages are platform thinking and module variants which provide a range of product variants using a small number of components. However, the field has not been fully explored within construction.Sweden has taken a leading role within industrialised timber housing. Much effort has been put in research and development of the timber structural system. Thereby, the building service systems (electrical and HVAC systems) has fallen behind in development. Currently, there are several actors involved, (e.g. consultants, subcontractors, wholesalers) that are individually procured on shortterm agreements. The actors remain in the traditional culture with dispersed views on value. To be able to break this dependency, enhanced industrialised practice for the building services is sought. Modularity is argued to aid in reducing the variation in production, lowering lead times and achieving control of material supply. Through modularity, production control can be achieved and value can be better managed, issues which are prevailing in industrialised timber housing. The purpose of the research is to evaluate the feasibility of modularity for building service systems within industrialised housing in Sweden. The thesis is based on two appended papers, discussing how modularity can be applied to industrialised housing, considering value generation and production control. The research strategy has been to follow previous case conclusions in the design of the next case. Empirical data have been gathered from five case studies ranging from a market survey to a consultant procurement. Five industrial housing companies have participated and data have also been collected from consultants and subcontractors. The results show that influence from traditional culture is particularly evident for the building service systems, as much work is still located on-site and actors in the supply chains act individually to optimise their own values, leading to lack of production control through e.g. faulty drawings. Further, the importance of cooperation within the trade is underlined in order to shield from the protectionism in the building service trade. The implication is the development of industry-wide common modules capturing internal values, and a company driven development process for management of company specific external values. The data have been analysed with a generic set of module drivers and the relation to value and production control, to identify forces for modular division. The findings point out the importance of drawing validation, possibility to isolate the process for parallel assembly and purchasing control through reduction of articles.The general conclusion is to design base module components only comprising necessary systems, which can be adapted to a generic building system. The suggestion is the development of a building service shaft and a building service inner ceiling. The analysis results emphasise the importance of interface design. In this sense are also included interfaces within the process and the supply chain, i.e. between activities and actors in the production process.Modularisering har tillämpats inom olika ämnesområden, t.ex. tillverkningsindustrin, datorbranschen, kognitiv vetenskap och utbildning. Generella fördelar är ett plattformstänkande och modulvarianter som ger en rad olika produktvarianter genom få antal komponenter. Däremot har modularisering inte blivit utforskat i samma utsträckning inom byggbranschen.Sverige har en ledande roll inom industriellt byggande av bostäder i trä. Mycket forskning och utveckling har inriktats mot stomsystemet medan installationssystem (el och VVS) hamnat efter i utvecklingen. Inom installationsbranschen finns flertalet aktörer (t.ex. konsulter, underleverantörer och grossister) som upphandlas individuellt, på korta avtal. Dessa befinner sig fortfarande i den traditionella byggkulturen med individuellt värdeskapande. För att kunna bryta denna kultur, söks en utveckling av det industriellt byggande. Modularisering bidrar till minskad variation i produktion, minskade ledtider och bättre styrning av materialförsörjning. Genom modularitet, kan produktionskontroll uppnås och värdeskapande tillgodoses, något som efterfrågas i dagens industriella byggande. Syftet med forskningen är att bedöma genomförbarheten av modularitet för installationssystem i industriellt byggda bostäder i Sverige. Avhandlingen bygger på två bifogade artiklar som diskuterar hur modularitet kan tillämpas på industrialiserade bostäder, speciellt inriktade på värdeskapande och produktionskontroll. Forskningsstrategin som har valts baseras på att kunskapen från en studie bidrar till utformningen av nästkommande studie. Empiriska data har samlats in genom fem fallstudier, från en marknadsundersökning till en konsultupphandling. Fem industriella träbyggare har deltagit. Information har också inhämtats från konsulter och underleverantörer.Resultaten visar att inflytande från den traditionella byggkulturen är särskilt stark för installationstekniken då mycket arbete fortfarande utförs på byggarbetsplatsen och aktörer i försörjningskedjan agerar individuellt för att optimera sina egna värden. Detta leder till bristande produktionskontroll genom t.ex. felaktiga ritningar. Dessutom betonas vikten av samarbete, med syftet att bryta protektionismen i branschen. Slutsatsen är att byggbranschen gemensamt måste utveckla moduler som fångar interna värden, och att företagen sedan utvecklar och optimerar egna externa värden.Uppgifterna har analyserats med generella moduldrivare relaterade till värde och produktionskontroll för att identifiera möjligheter till uppdelning i moduler. Resultaten betonar vikten av ritningsvalidering, möjlighet för parallell montering och kontroll på inköp genom minskning av antalet artiklar.Den allmänna slutsatsen är att utforma basmoduler som enbart omfattar nödvändiga system och som kan anpassas till ett generiskt byggsystem. Förslaget är att utveckla ett schakt och ett innertak. Resultaten betonar vikten av att noggrantdefiniera gränssnitt och även inkludera gränssnitt inom processer och leverantörskedjan, d.v.s. gränssnitt mellan aktiviteter och aktörer.

A method is introduced for structuring and guiding the development of end-to-end dependability arguments. The goal is to establish high-level requirements of complex software-intensive systems, especially properties that cross-cut normal functional decomposition. The resulting argument documents and validates the justification of system-level claims by tracing them down to component-level substantiation, such as automatic code analysis or cryptographic proofs. The method is evaluated on case studies drawn from the Burr Proton Therapy Center, operating at Massachusetts General Hospital, and on the Pret a Voter cryptographic voting system, developed at the University of Newcastle.

Efficient collection of photons from quantum memories, such as quantum dots (QDs) and nitrogen vacancy (NVs) centers in diamond, is essential for various quantum technologies. This thesis describes the design, fabrication, and utilization of novel photonic structures and systems to achieve potentially world-record photon collection from quantum dots. This technique can also be applied to NVs in diamond in the near future. Also, the NV- charged state has second-scale coherence times at room temperature that make it a promising candidate for solid state memories in quantum computers and quantum repeaters. NV- is an individually addressable qubit system that can be optically initialized, manipulated, and measured. On-chip entanglement generation would be the basis of scalability for quantum information processing technologies. These properties have enabled recent demonstrations of heralded quantum entanglement and teleportation between two separated NV centers. To improve the entanglement probability in such schemes, it is imperative to improve the efficiency with which single photons from a NV center can be guided into a low-loss single-mode waveguide. As such, a second component of this thesis focuses on the development of a photonic integrated circuit based on aluminum nitride that would incorporate pre-selected, long-lived NV center quantum memories as well as pre-selected, high-performance superconducting nanowire single-photon detectors (SNSPDs). This hybrid device would have the capability to perform on-chip entanglement of photons from separate quantum memories to build up a quantum repeater necessary for long-distance quantum communication and distributed quantum computing.

Theft of confidential data is prevalent. In most applications, confidential data is stored at servers. Thus, existing systems naturally try to prevent adversaries from compromising these servers. However, experience has shown that adversaries still find a way to break in and steal the data. This dissertation shows how to protect data confidentiality even when attackers get access to all the data stored on servers. We achieve this protection through a new approach to building secure systems: building practical systems that compute on encrypted data, without access to the decryption key. In this setting, we designed and built a database system (CryptDB), a web application platform (Mylar), and two mobile systems, as well as developed new cryptographic schemes for them. We showed that these systems support a wide range of applications with low overhead. The work in this thesis has already had impact: Google uses CryptDB's design for their new Encrypted BigQuery service, and a medical application of Boston's Newton-Wellesley hospital is secured with Mylar.

Full textAbstract:
As buildings are built more and more energy-efficient, precision of energy calculations needs to increase as the error decrease and the requirement to calculate “correctly” increases. At the beginning of a construction project, a builder must show that the building will comply with the National Board of Housing, Building and Planning's regulations when the project is completed in order to start the project. When the building is finished, it is tested through different feeds to investigate whether the building meets the requirements that the builder has claimed in the design step. The difficulty of calculating the energy requirement of a building so that it corresponds to the measured energy requirement is well known in the construction industry. In a school, heating of premises and tap water accounts for two thirds of the energy use and one third consists of lighting, kitchens and fans for ventilation. In a study with 7 newly built Swedish schools calculated and measured energy was examined, it was found that calculated and measured energy needs differed between -44% to + 28%. To make it easier to produce calculations of schools energy needs that correspond to real energy needs, this report examines which parameters are important for a school's energy needs and which parameters that makes the calculated and measured energy needs differ profoundly. Two preschools and two primary schools were examined in this study. A calculation model was built to examine which parameters have the greatest impact on a school's energy needs and to calculate the schools' energy needs. The measured and estimated heat energy requirements in the examined schools had a deviation of -3% and -16%. The measured and calculated electricity energy needs in the schools had a deviation of -2% and + 28%. The parameters that were important when calculating a school's energy needs turned out to be the efficiency of ventilation, tap water consumption, g-value, room temperature, supply air temperature, operating time of ventilation, operating time of commercial kitchens and electricity requirements for commercial kitchens. The result showed that when making energy calculations and trying to adjust and match it as closely as possible to the real measured values, the parameters with the most impact on this were efficiency of ventilation, g-value, supply air temperature, electricity demand for the commercial kitchen and the operating times of both the ventilation and the commercial kitchen.

Compressed sensing (CS) is a promising method for recovering sparse signals from fewer measurements than ordinarily used in the Shannon's sampling theorem [14]. Introducing the CS theory has sparked interest in designing new hardware architectures which can be potential substitutions for traditional architectures in communication systems. CS-based wireless sensors and analog-to-information converters (AIC) are two examples of CS-based systems. It has been claimed that such systems can potentially provide higher performance and lower power consumption compared to traditional systems. However, since there is no end-to-end hardware implementation of these systems, it is difficult to make a fair hardware-to-hardware comparison with other implemented systems. This project aims to fill this gap by examining the energy-performance design space for CS in the context of both practical wireless sensors and AICs. One of the limitations of CS-based systems is that they employ iterative algorithms to recover the signal. Since these algorithms are slow, the hardware solution has become crucial for higher performance and speed. In this work, we also implement a suitable CS reconstruction algorithm in hardware.

Full textAbstract:
It has been suggested that theoretical computer science (TCS) suffers more than average from a lack of intrinsic motivation. The reasons provided in the literature include the difficulty of the subject, lack of relevance to the informatics degree or future careers, and lack of enjoyment of the learning experience. This thesis presents evidence of these claims derived from the results of an expert survey. Increasing the students’ perceived control of the learning experience has been shown to increase student motivation in numerous different settings. A few of those also showed increased student performance. This thesis proposes that game-building can be such a setting for the area of TCS. Within the area of TCS, the focus will be on the modelling skills (finite state automata, push-down automata, Turing machines, CCS, etc.) since they form the majority of the curriculum at undergraduate level. It will be demonstrated how arbitrary TCS modelling skills can be mapped onto a game-building framework and allow the students to learn about the former by using the latter. It is hypothesized that the success of the approach depends on the amount of control given to the student. To test this claim, two experimental conditions were used in a repeated-measures design: (1) own-game and (2) pre-defined game. In the former, students are asked to write a game of their own, whereas in the latter, they are asked to copy a pre-defined game. A large demand for the own-game context was observed and results of its effect on performance and enjoyment are presented. Although no main effect of the owngame condition versus the pre-defined game condition was found in terms of either enjoyment or performance, some interesting interaction effects between condition and motivational type were unveiled.

Full textAbstract:
The residential sector in England is often identified as having the largest potential for emissions reduction at some of the lowest costs when compared against other sectors. In spite of this, decarbonisation within the residential sector has not materialised. This thesis explores the complexities of decarbonising the residential sector in England using a whole systems approach. It is only when the interaction between social, psychological, regulatory, technical, material and economic factors are considered together that the behaviour of the system emerges and the relationships between different system components can be explained giving insight into the underlying issues of decarbonisation. Building regulations, assessments and certification standards are critical for motivating and driving innovation towards decarbonising the building stock. Many existing building performance and evaluation tools are shown to be ineffective and confound different policy objectives. Not only is the existing UK SAP standard shown to be a poor predictor of dwelling level energy demand but it perversely incentivises households to increase CO2 emissions. At the dwelling level, a structural equation model is developed to quantify direct, indirect and total effects on residential energy demand. Interestingly, building efficiency is shown to have reciprocal causality with a household’s propensity to consume energy. That is, dwellings with high-energy efficiency consume less energy, but homes with a propensity to consume more energy are also more likely to have higher energy efficiency. Internal dwelling temperature is one of the most important parameters for explaining residential energy demand over a heterogeneous building stock. Yet bottom up energy demand models inadequately incorporate internal temperature as a function of human behaviour. A panel model is developed to predict daily mean internal temperatures from individual dwellings. In this model, socio-demographic, behavioural, physical and environmental variables are combined to estimate the daily fluctuations of mean internal temperature demand. The internal temperature prediction model is then incorporated in a bottom-up engineering simulation model. The residential energy demand model is then used to project decarbonisation scenarios to 2050. Under the assumption of consistent energy demand fuel share allocation, modelling results suggest that emissions from the residential sector can be reduced from 125 MtCO2 to 44 MtCO2 after all major energy efficiency measures have been applied, the power sector is decarbonised and all newly constructed dwellings are zero carbon. Meeting future climate change targets will thus not only require extensive energy efficiency upgrades to all existing dwellings but also the complete decarbonisation of end use energy demand. Such a challenge can only be met through the transformation of existing building regulations, models that properly allow for the effects of human behaviour, and flexible policies capable of maximising impact from a heterogeneous residential building stock.

Full textAbstract:
In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. The increased energy use and threat from CO2 emissions of the building sector create a need for energy efficiency. The important role that renovation of residential buildings will play in reducing the total energy used by the Swedish building sector as well as in reducing primary energy use and CO2 emissions on both the national and global levels has been the impetus for the studies included in this thesis. The aim of the current research is to develop a methodology from a system perspective which can be used to analyze the energy use, optimal life cycle cost (LCC), energy efficiency measure (EEM) package, indoor environment, CO2 emissions, and primary energy use of a building or a community during major renovation. The developed methodology accomplished at three different levels, i.e. building level, cluster level and district level. The methodology considers both energy efficiency and economic viability during building renovation and will also play an important role in overall urban planning. The studied buildings include both non-listed and listed residential buildings and the tools used include building energy simulation (BES), survey, technical measurements, LCC optimization and building categorization. The results show that the combination of BES, technical measurements and surveys provides a holistic approach for evaluation of energy use and indoor environment of the studied residential buildings. The results from the current study also show that the 2020 energy target, i.e., reduction of energy use by 20 %, for the building sector can be achieved by all the studied building types and that the total LCC of these buildings are below the cost-optimal point. In comparison, the 2050 energy target, i.e., reduction of energy use by 50 %, for the building sector may be achieved by the non-listed buildings, but when the constraints relevant to listed buildings are added the cost-optimality changes as some EEMs in direct conflict with the building’s heritage value may not be implemented. The investigation of primary energy use and CO2 emissions by the residential buildings show that the higher the energy saving, the lower the primary energy use becomes, and vice versa. With the same energy saving, the heating system with higher primary energy factor results in higher primary energy use. From a CO2 emissions point of view, EEM packages proposed to help buildings connected to a CHP based district heating system, to reduce the energy use or LCC are not consistently effective. Since these EEM packages will reduce district heating demand, the electricity produced in the CHP plant will also decrease. When the biomass is considered a limited resource, measures such as investment in a biofuel boiler are not favourable from the CO2 emissions point of view. The current study has also shown that combining building categorization method and LCC optimization method will help the community to reduce its energy use, primary energy use and CO2 emissions in a systematic and strategic way.I Sverige, står byggnadssektorn för cirka 40 % av den totala energianvändningen och cirka 10 % av CO2-utsläppen. Idag är mer än 60 % av befintliga svenska bostäder över 40 år gamla och i stort behov av renovering. Dessutom är 15 % av alla flerbostadshus och 27 % av alla småhus byggda före 1945. Den ökade energianvändningen och hotet från CO2-utsläpp från byggsektorn skapar ett behov av energieffektivisering. Grunden för studierna i denna avhandling är den stora betydelse som renoveringen av bostäder har, såväl för att kunna minska den totala energianvändningen som den primärenergianvändningen och CO2-utsläppen på både nationell och global nivå. Syftet med denna forskning är att utveckla en metodik ur ett systematiskt perspektiv som kan användas för att analysera energianvändning, finna optimal livscykelkostnad (LCC), skapa energieffektiviseringsåtgärdspaket, undersöka inomhusmiljöer, beräkna CO2-utsläpp och primärenergianvändning i en byggnad eller ett samhälle vid omfattande renovering. Den utvecklade metodiken som har använts i de aktuella studierna är på tre olika nivåer: byggnadsnivå, klusternivå och stadsdelsnivå. Metodiken avser både energieffektivitet och ekonomisk lönsamhet vid renovering av byggnader och kommer också att spela en viktig roll i den övergripande stadsplaneringen. De studerande byggnaderna i denna avhandling innefattar både historiska och icke-historiska bostäder. De använda verktygen inkluderar building energy simulering (BES), enkätundersökning, tekniska mätningar, LCC-optimering och byggnadskategorisering. Resultaten visar att kombinationen av BES, tekniska mätningar och enkätundersökning ger en god helhetsbild för utvärdering av energianvändning och inomhusmiljö av den studerade byggnaden. Resultaten från den aktuella studien visar också att 2020-energimålet, d.v.s. en minskning av energianvändningen med 20 % till 2020 av byggsektorn, kan uppnås i alla undersökta byggnader och att den totala LCC av dessa byggnader ligger under den kostnadsoptimala punkten. I jämförelse, kan 2050-energimålet, d.v.s. en minskning av energianvändningen med 50 % till 2050, kan uppnås i icke-historiska byggnader, men med hänsyn tagen till begränsningarna för historiska byggnader, ändras de kostnadsoptimala lösningarna, eftersom vissa energieffektiviseringsåtgärder är i direkt konflikt med byggnadens kulturhistoriska värde och därför inte kan genomföras. Undersökningen av primärenergianvändning och CO2-utsläpp i de studerade byggnaderna visar, att ju högre energibesparingen är, desto lägre blir primärenergianvändningen, och vise versa. Med lika mycket energibesparing, resulterar värmesystemet med högre primärenergifaktor i högre primärenergianvändning. Sett från CO2-utsläppssynvinkel, är de energieffektiviseringsåtgärdspaket, som kan hjälpa byggnader anslutna till ett kraftvärmebaserat fjärrvärmesystem att minska energianvändningen eller LCC, inte effektiva, eftersom dessa åtgärdspaket kommer att minska fjärrvärmeanvändningen. Detta leder till att mängden producerad el i ett kraftvärmeverk också kommer att minskas. När biobränsle betraktas som en begränsad resurs, är åtgärder som investering i en biobränslepanna inte energieffektiva från en CO2-utsläppssynvikel. Den aktuella studien visar också att kombinationen av byggnadskategorisering och LCC-optimering kommer att hjälpa byggnadssektorn att minska sin energianvändning, primärenergianvändning och CO2-utsläpp på ett systematiskt och strategiskt sätt.

Full textAbstract:
The ongoing transformation of the energy system along a more sustainable trajectory requires advancements in a range of technological fields, as well as active involvement of different societal groups. Integration of photovoltaic (PV) systems in the built environment in particular is expected to play a crucial long-term role in the deployment of renewable energy technologies in urban areas, demanding the successful cooperation of planners, architects, engineers, scientists and users. The realisation of that technological change will require innovation at both an individual (within firms and organisations) and a collective (sector) level, giving rise to systemic approaches for its characterisation and analysis of its drivers. This study investigates the processes that either accelerate or hinder the development and diffusion of Building-Integrated PV (BIPV) applications into the market. Affected by developments in both the renewable energy and construction industries, the BIPV innovation system is a multi-sectoral case that has been explored only partially up to now. Acknowledging the fact that drivers of innovation span the globalised BIPV supply chain, this research adopts both an international and a national spatial perspective focusing on the UK. The analysis is based on a novel analytical framework which was developed in order to capture innovation dynamics at different levels, including technological advancements within firms, competition and synergy with other emerging and established innovation systems and pressures from the wider socio-economic configuration. This hybrid functional framework was conceived by combining elements from three academic strands: Technological Innovation Systems, the Multi-Level Perspective and Business Studies. The empirical research is based on various methods, including desktop research, semi-structured interviews and in-depth firm-level case studies. A thorough market assessment provides the techno-economic background for the research. The hybrid framework is used as a guide throughout the empirical investigation and is also implemented in the analytical part of the study to organise and interpret the findings, in order to assess the overall functionality of the innovation system. The analysis has underlined a range of processes that affect the development and diffusion of BIPV applications including inherent technological characteristics, societal factors and wider transitions within the energy and construction sectors. Future approaches for the assessment and governance of BIPV innovation will need to address its hybrid character and disruptiveness with regards to incumbent configurations, in order to appreciate its significance over the short and long term. Methodological and conceptual findings show that the combination of insights from different analytical perspectives offers a broader understanding of the processes affecting innovation dynamics in emerging technologies. Different approaches can be used in tandem to overcome methodological weaknesses, provide different analytical perspectives and assess the performance of complex innovation systems, which may span multiple countries and sectors. By better reflecting complexities, tensions and synergies, the framework developed here offers a promising way forward for the analysis of emerging sustainable technologies.

Full textAbstract:
This thesis presents a semantic-based modeling approach for describing Service-Oriented Architectures (SOA). Ontologies are utilized as a major representation mechanism for describing various elements available in the architecture. The methodology proposes an architecture specification mechanism to constuct a unified ontology that enables transition from design concerns to the modeling elements. A multi-level modeling is also achieved by employing Model-Driven Engineering (MDE) techniques to describe various models at different stages of the software architecture. This aims to organize service-oriented models within a number of architecture viewpoints in order to provide an architectural perspective for SOA. The use of ontologies for model specification also allows us to make use of ontology mapping to specify the transformation between different models. Additionally, we present a case study to demonstrate the proposed methodology on a real-world healthcare scenario.

In this thesis a framework for Security Operation Centers (SOCs) is proposed. It was developed by utilising Systems Engineering best practices, combined with industry-accepted standards and frameworks, such as the TM Forum’s eTOM framework, CoBIT, ITIL, and ISO/IEC 27002:2005. This framework encompasses the design considerations, the operational considerations and the means to measure the effectiveness and efficiency of SOCs. The intent is to provide guidance to consumers on how to compare and measure the capabilities of SOCs provided by disparate service providers, and to provide service providers (internal and external) a framework to use when building and improving their offerings. The importance of providing a consistent, measureable and guaranteed service to customers is becoming more important, as there is an increased focus on holistic management of security. This has in turn resulted in an increased number of both internal and managed service provider solutions. While some frameworks exist for designing, building and operating specific security technologies used within SOCs, we did not find any comprehensive framework for designing, building and managing SOCs. Consequently, consumers of SOCs do not enjoy a constant experience from vendors, and may experience inconsistent services from geographically dispersed offerings provided by the same vendor.

Full textAbstract:
From the field of control theory, we can see that varying communication delays in a control system may be hard or even impossible to handle. From this point of view it is preferable to have these delays bounded and as small and as possible in order to adapt the control process to them. On the other hand, in some cases delays are inevitable and must be handled by the control system.
A control system may for different reasons be distributed, e.g., because of a distributed environment or severe environment demands such as heat or dust at some locations. Information in such a system will suffer from delays due to transportation from one place to another. These delays often show up in a random fashion, especially if a general network is used for transportation. Another source of delays is the system environment itself. For predictability reasons a real-time database is preferable if the delays are to be controlled.
A straightforward way of handling delays in a control system is to build the system such that delays are constant, i.e., to build a time invariant system. The time from sensor reading to actuation is made constant either by adding a suitable delay to achieve a total constant delay or by using time-triggered reading and actuation. These are simple ways of controlling the delays, but may be very inefficient because worst-case execution time must always be used. Other ways of handling varying delays are by using more tolerant control algorithms. There are two suitable control models proposed by Nilsson (1998) for this purpose. The tolerant algorithm approach is assumed in this work.
This thesis uses a distributed active real-time database system as a basis for building control systems. One of the main objectives is to determine how active functionality can be used to express the control system, i.e., how rules in the database can be used to express the control algorithm and for handling propagation of information. Another objective is to look at how the choice of consistency level in the database affects the result of the control system, i.e. how different consistency level affects the delays. Of interest is also to characterize what type of applications each level is suited for.

Full textAbstract:
In this dissertation, I first incorporate declustered redundant array of independent disks (RAID) technology in the existing system by maximizing the aggregated recovery I/O and accelerating post-failure remediation. Our analytical model affirms the accelerated data recovery stage significantly improves storage reliability. Then I present a proactive data protection framework that augments storage availability and reliability. It utilizes the failure prediction methods to efficiently rescue data on drives before failures occur, which significantly reduces the storage downtime and lowers the risk of nested failures. Finally, I investigate how an active storage system enables energy-efficient computing. I explore an emerging storage device named Ethernet drive to offload data-intensive workloads from the host to drives and process the data on drives. It not only minimizes data movement and power usage, but also enhances data availability and storage scalability. In summary, my dissertation research provides intelligence at the drive, storage node, and system levels to tackle the rising reliability challenge in modern HPC datacenters. The results indicate that this novel storage paradigm cost-effectively improves storage scalability, availability, and reliability.

The application of Expert Systems in the Geotechnical and
Construction fields of Civil Engineering has been
investigated and a prototype knowledge based Expert System
(SITEPREP) has been developed for site preparation when
constructing city building foundations.
In developing this system the problems of knowledge
acquisition and the selection of a suitable expert system
building environment have been investigated. It has been
concluded that knowledge acquisition is the most important
criterion when developing an expert system. Further, it has
been found that the most efficient method to collect
expertise is to develop an initial system in-house, then
have the experts validate and provide further knowledge
for the system. An existing shell (LEONARDO 3 .18) has
provided the medium in which to encapsulate the experts'
knowledge. This shell has also ensured rapid system
development. The various methods of obtaining knowledge, in
particular interviewing, are discussed in the thesis.
A review of the effects of foundation construction on
existing buildings, and the methods of protecting these
structures was conducted to provide the documented
expertise on which the initial in-house system has been
based. Prediction of ground movements due to adj a cent
construction is considered and the effects of different
soil, shoring and workmanship parameters are combined into
one set of "zones of movement" for use in the expert
system.
The expert system, SITEPREP, has been evaluated by
practising construction and geotechnical engineers. The
development of this expert system has shown that such

Full textAbstract:
The need for housing in Sweden has been showing a constant increase over the past couple of years. However, this situation might change in 2018 since there are indications that the increase in demand will reach its peak. On the other hand, the use of timber as a load bearing structure has become more popular in the multi-family house building sector. It is competing with concrete and steel frames, and its market share might even reach 50% by the year of 2025. Adding the involvement of customers in house design decisions and a high level of customization, the conclusion is that timber house building must continue the development towards mass customization. There is a lack of knowledge on how mass customization is developed and implemented regarding off-site manufacturing systems. In this thesis, a contribution is made to manufacturing system development in timber house building by proposing a novel approach to aligning off-site manufacturing systems to the requirements of production strategy, market needs, product design, and manufacturing processes. The proposed conceptual framework is a synthesis of the knowledge gained from three empirical studies and different methods found in theories of changeable manufacturing systems, mass customization, and manufacturing system development. The research purpose addressed by the presented work, is to increase the knowledge on how the development potential of off-site manufacturing systems can be identified in mass customization-oriented timber house building. Case study research was applied to gather the empirical data. The data collection and analysis methods used in the empirical studies can be useful when discussing the potential improvements. However, these data are not comprehensive enough in terms of presenting a holistic view of off-site manufacturing and consideration of the market as well as variation in product and processes. Therefore, a comprehensive set of requirements is proposed in the conceptual framework together with a step by step description of how the development potential of off-site manufacturing systems can be identified.Behovet av bostäder i Sverige har ständigt ökat under de senaste åren. Denna situation kan dock förändras 2018, eftersom det finns tecken på att ökningen av efterfrågan kommer att nå sin topp. Å andra sidan har användningen av trä som lastbärande konstruktion blivit mer populär i flerfamiljshusbyggnaden. Det konkurrerar med betong- och stålstomme och dess marknadsandel kan till och med nå 50% år 2025. Att lägga kundernas medverkan i husdesignbeslut och en hög anpassningsnivå är slutsatsen att trähusbyggnaden måste fortsätta utveckling mot mass customization (MC). Det finns brist på kunskap om hur MC utvecklas och implementeras när det gäller off-site tillverkningssystem. I denna avhandling görs ett bidrag till tillverkningssystemutveckling i trähusbyggnad genom att föreslå ett nytt tillvägagångssätt för att anpassa tillverkningssystem till de olika kraven av produktionsstrategier, marknaden, produktdesign och tillverkningsprocesser. Den föreslagna konceptuella ramen är en sammansättning av kunskapen från tre empiriska studier och olika metoder som finns i teorier om förändringsbara tillverkningssystem, MC och tillverkningssystemutveckling. Forskningssyftet med det presenterade arbetet är att öka kunskapen om hur utvecklingspotentialen av off-site tillverkningssystem utanför anläggningen kan identifieras i MC-orienterad trähusbyggnad. Fallstudier användes för att samla empiriska data. Datainsamlings- och analysmetoderna som används i de empiriska studierna kan vara användbara när man diskuterar potentiella förbättringar. Men denna information är inte tillräckligt komplett när det gäller att presentera enhelhetsbild av off-site tillverkning, utan en bedömning av marknaden samt kunskap om variationer i produkt- och processer behövs även. Därför presenteras det konceptuella ramverket, inklusive en kravlista samt en stegvis beskrivning av hur utvecklingspotentialen för off-site tillverkningssystem kan identifieras.

Bibliography: leaves 41-44.Sustainable construction is a tenns that emerged with the introduction of the concept of sustainable development in construction. Therefore, sustainable construction embraces socio-economic, cultural, biophysical, technical and process-orientated aspects of construction practice and activities. The progress towards sustain ability in construction may be assessed by implementation of good practice in building developments. Therefore, building environmental assessment methods are valuable tools of indicating such a progress as well as promoting sustainable approaches in construction. An effective building environmental assessment method requires definition of explicit benchmarks and weightings. These should take into account environmental, social and economic contexts of building developments. As the existing building environmental assessment methods largely ignore socioeconomic impacts of building developments, the implementation of a participatory approach in the development of benchmarks and weighting systems could greatly contribute to a more meaningful incorporation of social and economic aspects into the assessment process. Furthennore, the participation of stakeholders in establishing qualitative benchmarks and weights should increase the credibility of such a process. The participatory approach could allow for education of all stakeholders about the potential environmental, social and economic consequences of their decisions and actions, which is so vital for achieving their commitment to strive towards sustainable construction.

Full textAbstract:
The expansion of photovoltaic plants has increased significantly within the EU and in Sweden, where a contributing cause has been a higher environmental thinking and lower prices for solar cell installations. Interest in installing solar cells has increased in society as a whole and an increasing number of municipalities are interested in solar cells. One of these municipalities is Forshaga municipality, which strives to be climate neutral until 2030. This study examined whether a number of selected municipal properties in the Forshaga municipality were suitable for installing solar cells based on the degree of self-use and the degree of self-sufficiency and the electricity cost of produced electricity (LCOE - Levelized cost of energy). The study also examined whether these selected properties would be suitable for solar cells if certain conditions were changed to simulate that they were located in another location with different conditions. Of the properties included in the study, there was a care home, two schools, Forshaga municipal house, a wastewater treatment plant and a waterplant. Of the examined municipal properties, a school, the nursing home and the municipal house were considered most suitable for solar cells based on the above criteria. The property that was considered most suitable was the Grossbolskolan which was the smaller of the two schools. Grossbolskolan had a self-utilization rate and a self-sufficiency rate of 87 and 15 percent respectively and the lowest cost for the produced electricity by about 0.88 SEK/kWh. The municipal house and the care home had a slightly higher production cost for the produced electricity. Some conclusions could be drawn from the part of the study that examined whether the properties were suitable for mounting solar cells if they had been placed in another location with other conditions. One conclusion was that the properties should have a similar electricity consumption as the investigated properties in this study, with a higher electricity consumption daytime when the solar cells produce the most to obtain a high self-use. The degree of selfuse was highest for the plants that were located in the east / west direction, which indicates that the electricity consumption in these type properties was more suitable for solar cell installations whose production is more widespread throughout the day. In order for the repayment period not to exceed the assumed life expectancy of the solar cell plant of 25 years, the self-use rate should not be less than 50 to 60 percent. Finally, the study also found that the properties recommended as suitable had between 1 - 3.5 m2 solar cells / MWh annual electricity use in the property, which can be used as a guideline value to see if the property is suitable for solar cells. If this value were lower, the self-sufficiency rate was low, if it was greater, the self-utilization rate was low.

The use of computers within the electronic environment has led to rapid and dynamic changes in the way governments and businesses operate. One of the significant outcomes of computerization is that managing electronic records now relies on IT and it needs to be integrated into the business processes of an organization. Therefore electronic records management (ERM) not only requires the involvement of key players in recordkeeping, such as records managers and archivists, but also IT personnel and administrators under a common shared responsibility to establish a credible electronic records management programme. According to McLeod, Hare and Johare (2004) managing records in the electronic environment is not only a major challenge but also increasingly a strategic issue for organizations in both the public and private sectors. They suggested that “a key factor in meeting both the challenge and addressing the strategic management is the provision of education and/or training for employees and potential employees (i.e students). In particular, providing this at the appropriate level of detail and in the appropriate areas of the subject, commensurate with roles and responsibilities so that these people can discharge, both effectively and efficiently, their responsibilities for managing records in the electronic environment”. Within this context, this paper examines the education and training opportunities on ERM worldwide and in Asia.

Full textAbstract:
Globally, buildings utilize 35 % of the final energy use and contribute to approximately one-third of CO2 emissions. Hence, reducing the energy use of buildings contributes to a large amount of CO2 emissions to be decreased. The building’s energy use is affected by many parameters, including wind which plays an important role in building energy use. In this thesis, we aim to analyze the impact of wind parameters on building’s energy use on two multi-family building types with natural ventilation at various wind sheltering conditions at different climatic zones in Sweden. Building energy simulation models (BES) of a standalone and an attached building located in Visby, Sweden, were constructed with the use of the dynamic BES IDA ICE. Luleå and Malmö were taken as other two study locations to investigate the impact from different climate zones. The simulations were performed with the constructed calculation models, with the various wind sheltering conditions at the different climatic zones to calculate the energy use of the buildings and ventilation and infiltration losses. The sensitivity analysis was then carried out based on changing the wind profile of the climate file to evaluate the impact of wind on the ventilation and infiltration losses, as well as the heat energy use of the building. The results showed that the energy use for space heating of the attached building was 89 kWh/m2 (38 %) lower than the standalone building. The energy use varies between 9–20 kWh/m2 (3–10 %) considering the exposed, semi-exposed and sheltered wind condition for the two building types. In the different climate zones, Luleå has 47 kWh/m2 higher energy use compared to Visby and Malmö for the standalone building. The corresponding figure for the attached building is 25 kWh/m2. The sensitivity analysis show that when the wind speed is increased by 100 %, the ventilation and infiltration losses increase between 3563–18683 kWh (54–61 %) while the energy use of the building increases between 11–54 kWh/m2 (20–27 %).

L'auto-assemblage moléculaire est désormais considéré comme l'une des approches les plus prometteuses pour la conception de matériaux à nanostructures complexes. Cependant, les récents progrès effectués ont aussi amené la nécessité d'améliorer la compréhension des mécanismes régissant la flexibilité des molécules. Il a ainsi été décidé d'étudier l'effet de la composition des briques moléculaires sur leur processus d'assemblage, et la labilité structurale des systèmes assemblés. De manière à pouvoir comparer rigoureusement les résultats expérimentaux, un seule morphologie de briques moléculaires, en forme de "bâtonnet", a été choisie et trois groupes distincts de molécules ont été sélectionnés : non-polaires, qui ne possèdent pas de dipôle important, monofonctionelles, lesquelles possèdent une terminaison polaire et une seconde non-polaire, et bifonctionelles, constituées d'un groupe polaire à chaque extrémité séparés par une chaine non-polaire Ainsi, l'influence des groupements dipolaires sur la labilité de la nanostructure finale du matériau a pu être explorée. Cette étude permet ainsi de mettre en exergue la remarquable diversité des flexibilités structurales qui peuvent être rencontrées dans les systèmes auto-assemblés. De plus, elle dévoile le potentiel des mouvements moléculaires locaux en tant qu'approche encourageante pour fonctionnaliser des structures auto-assemblées supposées inertes ou contraintes.

Full textAbstract:
A modern home contains varieties of electronic equipment and systems like: TV, Hi-fi equipment, central heating systems, fire alarm systems, security alarm systems, lighting systems etc. Enabling these devices to communicate is the first step towards the long-predicted smart home, but this requires communication standards to follow. It can be anticipated that the technology must be wireless in order for such network to be feasible. Large set of standards are present for as well wired as wireless communication in between such devices, but today no standard communication interface available.
The goal of this project is to survey available standards for short-range wireless communication, and to evaluate and compare their capabilities to become a general standard for home automation. The evaluation must take such aspects as security, range, network architecture and the heterogeneous set of devices into consideration. Furthermore, this thesis proposes how to interconnect the home network to the external network for remote supervision and control.

This thesis implemented a prototype of an expert system shell for support of engineering design activities in the way of logic programming. The development of the system is based on the theoretical framework for knowledge-based system design and the formal modeling concepts. Under the above methodologies, two knowledge representations, production rule system and system entity structure, are incorporated into the knowledge base for figuring design structures. Here the production system scheme is employed for synthesis of design models represented in the system entity structure. The whole system is coded in Turbo Prolog and a specific domain knowledge, namely a local area network, is currently used as a testbed environment.

Full textAbstract:
The structural engineer should not only be able to perform design calculations but also findmore efficient solutions for building parts. The purpose of this thesis is to redesign a concreteframe for a house (an apartment building) into a light frame with steel columns andcompartment walls, as well as perform a life cycle analysis for materials on both frames anddetermine the frame with the lowest environmental impact.The result shows that the lightweight frame with steel columns and compartment walls is amuch better choice for the environment as it stands only for 60 000 kg CO2e compared toconcrete frame which stands for 163 000 kg / CO2e. The steel frame emits about 60% lessemissions than the concrete frame.By optimizing steel columns in the upper floors and choosing smaller columns led to ten tonsless mass of steel and less emissions by 15 000 kg / CO2e.The selected compartment wall has a thickness of 309 mm which is 6 mm thicker than theexisting wall which results in a reduction of the area of house by 6 square meters throughoutthe house which can be expensive depending on the location of the house.In conclusion, the material concrete is good when it is needed due to requirements on fire,noise, and durability but also less suitable when not needed. In this case, it is useless with thematerial concrete as the outer wall and can therefore be replaced by a steel columns andcompartment wall instead.Konstruktören ska inte endast kunna utföra beräkningar utan även hitta effektivare lösningar till byggnadsdelar. Syftet med detta examensarbete är att dimensionera om en betongstomme för ett flerbostadshus till en lättstomme med stålpelare och utfackningsväggar samt även utföra en livscykelanalys för material på stommar och bestämma stommen med lägst miljöpåverkan.Resultatet visar att lättstomme med stålpelare och utfackningsvägg är ett mycket bättre val för miljön då står den för 60 000 kg/CO2e jämfört med betongstomme som står för 163 000 kg/CO2e. Stålstommen släpper ut ungefär 60 % mindre utsläpp än betongstommen.Optimering av stålpelare i övre plan och att välja mindre pelare ledde till tio ton mindre massa stål och även mindre utsläpp på 15 000 kg/CO2e.Den valda utfackningsväggen har tjocklek 309 mm vilket är 6 mm tjockare än den befintliga väggen som i sin tur resulterar i en areaförlust med 6 kvadratmeter i hela huset vilket kan vara dyrt beroende på husets läge.Som slutsats är att materialet betong är bra när det behövs på grund av till exempel brand, ljud och beständighet men även mindre lämpligt när det inte behövs. I detta fall är det mindre lämpligt med materialet betong som yttervägg och man kan därför använda utfackningsvägg med stålpelare istället.

Full textAbstract:
In today's highly competitive business environment, innovation and new product introduction are recognized as the sustaining forces of corporate success. The early phases of new product development, collectively known as the 'front-end', are crucial to the success of new products. Building a fuzzy front-end decision support system, balancing the needs for analytical soundness and model robustness while incorporating decision-maker's subjectivity and adaptability to different business situations, is a challenging task. A process model and a structural model focusing on the different forms of uncertainties involved in new product introduction in a global telecommunication market are presented in this dissertation. Fuzzy measure theory and fuzzy set theory are used to build a quantitative model of the executive decision-process at the front-end. Solutions to the problem of exponential complexity in defining fuzzy measures are also proposed. The notion of constrained fiizzy integrals demonstrates how the fuzzy measure-theoretical model integrates resource allocation in the presence of project interactions. Forging links between business strategies and expert evaluations of critical success factors is attempted through fuzzy rule-based techniques in the framework of the proposed model. Interviews with new product managers of several American business firms have confirmed the need for building an intelligent front-end decision support system for new product development. The outline of a fuzzy systems development methodology and the design of a proof-of-concept prototype serve as significant contributions of this research work toward this end. In the context of executive decision making, a usability inspection of the prototype is carried out and results are discussed. A computational analysis, based upon methods of tactical systems simulation, measures the rank order consistency of the fuzzy measure theoretical approach in comparison with two competing fuzzy multiple attribute decision models under structural variations of the underlying models. The results demonstrate that (1) the modeling of the fuzzy numbers representing the linguistic variables, (2) the selection of the granularity of the linguistic scales, and (3) the selection of the model dimensions significantly affect the quality of the decisions suggested by the decision aid. A comprehensive plan for future validation of the decision aid is also presented.

Full textAbstract:
The main questions today concerning thermal systems are their economical and environmental impacts. These entities are generally, at present, assessed on the basis of operation performances of newly installed/designed systems, during an assumed lifetime period. While this is the common way of perceiving thermal systems, performance-over-time will change as an effect of degradation, and not solely of different operation scenarios. How and to what extent is the question that needs assessing in order to evaluate if these changes will jeopardise the intended system performance requirement, hence service life (SL). The lack of knowledge/approaches and tools for assessing durability and performance-over-time of thermal systems complicates the task of incorporating these aspects in engineering. In turn, this pro-active assessment and analysis is in line with today’s performance based directives, laws and regulations; of which the working life is an essential part. The durability of materials, components and systems is not a topic that is an end in itself, but becomes a vital part in a comprehensive perspective as sustainability. The lifetime performance assessment of thermal systems, as presented in this thesis, shows that it is a vital part of the R&D in the quest of sustainable energy/thermal systems and energy use. This thesis gives knowledge to the thermal (energy) system/technology R&D and engineering sector, regarding durability and lifetime performance assessment methodologies; but also to the durability of construction works sector, regarding the needs for assessing lifetime performance of materials and components in relation to system performance. It also presents descriptions of requirements on construction works. Specifically, the studies presented in the thesis show how durability and lifetime performance assessment of thermal systems may be sought, with knowledge on: methodologies, exposure test set-ups, modelling and the attainment and use of adequate tools. The main focus is on performance-over-time modelling, tying material/component degradation to altered thermal performance, thereby attaining performance-over-time assessment tools to be used in order to incorporate these aspects when engineering thermal systems; hence enabling the forecasting of SL. The presented work was predominantly done in association to the EU project ENDOHOUSING. The project developed a solar-assisted heat pump system solution, with heat storage, to provide the thermal energy to meet space heating, cooling and hot water requirements for domestic houses in different regions of the EU. The project constituted the platform for the work presented in this thesis, thereby outlining the main context with studies on durability and lifetime performance of: flat plate solar collectors ground heat sources/storages and interaction with a heat pump system evaluation of the ENDOHOUSING solar-assisted heat pump system The thesis also presents a study of SL prediction and estimation of district heating distribution networks (an additional thermal system application). In this particular context, the Factor Method is proposed as a methodology. The main issue of lifetime performance of thermal systems is how and to what extent performance reduction in individual materials or components influence the overall system performance, as the essence of energy/thermal system sustainability is system performance.QC 20100810

Full textAbstract:
The climate crisis is becoming more prominent in everyday life and the construction industry plays a significant role. The study aims to optimize the climate of a fictional house with exterior walls made of wood. By investigating the climate impact of a building with a solid wooden frame depending on the heating system. The study will focus on two different frame systems, one of which is made of cross-glued wood and one of IsoTimber. The questions are what climate impact a solid wood building does have. What dimension of cross-glued wood is required to meet BBR's requirements? Which combination of frame system and heating system is the most optimal for Malmö and Stockholm? How many years does it take for the heating to have a greater climate impact than the manufacture of the building? How much climate impact will the most optimized building have after 50 years? In the VIP-Energy program, energy calculations have been performed. Quantity and energy calculations have then been translated into carbon dioxide equivalents in the BM program to calculate the climate impact for the buildings with associated heating systems. The results show that cross-glued wood has a lower general climate impact than the frame of IsoTimber. The dimension for meeting BBR's energy requirements with a cross-glued wood frame is 330 mm. The most optimized combination of frame system and heating from a climate point of view is IsoTimber 300 mm with district heating for Malmö and Stockholm. The results show that energy consumption from heating will have a greater climate impact than production for the most optimized alternative only after 22 years for Malmö and 44 years for Stockholm. The building with the least climate impact after 50 years is IsoTimber 300 mm with district heating where the climate impact is 57,7 ton CO2e in Malmö and 43,7 ton CO2e in Stockholm. The study shows that reliable conversion factors are required to translate components and heating systems into carbon dioxide equivalents. The current conversion factor for heating when district heating is used differs between the climate zones, which means that the result is widely distributed. The best optimized alternative, 300 mm IsoTimber with district heating is a good alternative with a low climate impact that still maintains a high level of comfort for the user.

Full textAbstract:
As organizations seek to control their practices through Business Process Management (BPM - or the process of improving the efficiency and effectiveness of an organization through the automation of tasks), workflow management systems (WFMS) have emerged as fundamental supporting software tools. A WFMS must maintain process state while managing the utilization of people and applications (resources), data (context), and constraints (rules) associated with each of the tasks [Baeyens04]. It must also be configurable so it can be easily adapted to manage specific workflows within any application domain. Finally, the WFMS should be flexible enough to allow for changing business needs. In order to meet these challenges, a WFMS must provide access to process and document definition tools as well as administrative tools.
In this project we have used an "End User Developmentn (EUD) approach [Repenning04] to build a stand-alone web-based WFMS which offers the non-technical end user the ability to design, launch, and manage multiple automated workflows and their associated documents. It empowers end users to build and customize their own systems without requiring from them skills other than those associated with their domain of expertise.

Full textAbstract:
In this dissertation the complex, dynamic, contextual and multi-dimensional practice of teachers’ use of digital technologies in their everyday work has been illustrated and presented. The research draws upon the experience of teachers and school leaders from two compulsory schools as well as representatives from the municipal Department of Education and IT-unit within a municipality in the south of Sweden. A focused ethnographic approach has been undertaken and applied observations and interviews. Systems Thinking, specifically Soft Systems Methodology in combination with Cognitive Mapping have been applied to analyze the empirical material. The theoretical foundation builds upon teachers’ worldview towards digital technologies, because it is noted that teachers more easily adopt and use innovations that are in accordance with their personal thoughts and beliefs about teaching and learning. Further, teachers’ attitude and perception towards use of digital technologies are addressed as well as the role of school leadership. Additionally, importance of context, teachers’ knowledge and pedagogics have been discussed referring to various frameworks. The dissertation aims to illuminate the complex nature of teachers’ everyday practice. To gain understanding of the situation as a whole, there is also need to shed light on various aspects and underlying perspectives. Thus, this research aims to illuminate and advance the understanding of the complexity of compulsory school teachers’ everyday work practices using digital technologies. The outcome of this dissertation illustrates the complexity of teachers’ everyday practices as well as additional issues adding to the complexity, and shows that these complex issues are worthy of further study. Among the issues emerged from this dissertation are differences in regard to how the complex situation is understood because different actors have multiple and sometimes conflicting worldviews. Ambiguities in core objectives and relevant concepts were found. Additionally, a pervasive lack of understanding about the realities of daily education and teaching practices, including variances in worldviews and mindsets was found adding to the complexity of teachers’ everyday practice using digital technologies.

Full textAbstract:
Cell-cell and cell-environment interactions are controlled by a set of local rules that dictate cell behavior. With such local rules, emergence of computationally meaningful building blocks and hierarchies can be observed. For example, at the cellular level organization in the visual system, receptive field of a retinal ganglion cell displays an activation inhibition behavior that can be modeled as Mexican Hat wavelet or Difference of Gaussians. This precise organization is the product of a harmonious collaboration of different cell types located at the lower levels in a hierarchical structure for each ganglion cell. Moreover, a similar hierarchical organization is observed at higher levels in the visual system. This thesis investigates the visual system from several perspectives in an effort to explore the biological/computational principles underlying these local rules. The investigation results in a hybrid computer model that can combine the advantages of evolutionary and developmental principles to explore the effects of local rules on cellular differentiation, retinal mosaics, layered structures and network topology.

Full textAbstract:
Mobile technologies are emerging as one way to help address health challenges in many countries, including in Least Developed Countries. Mobile technology can reach a large share of the population but in order to provide effective support to healthcare services, technology, information collection and dissemination, and work processes need to be well aligned. The thesis uses a design science methodological approach and mixes qualitative and quantitative data analysis to address the question of, How can mobile technologies be effectively integrated with routine healthcare services? The study concerns the design, implementation, and evaluation of a mobile technology-based system, called SMSaúde, with the aim of improving the care of patients with HIV/AIDS and tuberculosis in Mozambique. The work started with the elicitation of functional and user requirements, based on focus group discussions. An important challenge, as in many mHealth interventions, was the integration with routine healthcare services and the existing IT systems, as well as developing a scalable technical structure. The system has now been in routine use since 2013 in more than 16 healthcare clinics in Mozambique. Evaluation was done by a randomised controlled study. Analysis of patient records showed that retention in care in urban areas was significantly higher in the intervention group than in the control group. In a user study both patients and health professionals were very positive to the system. The thesis contributes to research by demonstrating how information system artefacts can be constructed and successfully implemented in resource-constrained settings. The practical contributions include the designed artefact itself as well as improved healthcare practices and mHealth policy recommendations.

Full textAbstract:
Building energy performance has always been important in the cold climate of Sweden, Norway and Finland. To meet the goal that all new buildings should be nearly zero-energy buildings by 2020, set in the EU directive 2010/31/EU [1] on the energy performance of buildings (EPBD recast), the building sector in Europe now faces a transition towards buildings with improved energy performance. In such a transition, a discussion is needed about the objective of the improvement – why, or to what end, the building energy performance should be improved. The objective of improving building energy performance is often a political decision, but scientific research can contribute with knowledge on how the objectives can be achieved. This thesis addresses how the indicators used in the requirements used to achieve building energy performance in Sweden, Norway, and Finland, and the methods used to evaluate these requirements, reflect building energy performance. It also addresses difficulties in achieving comparable and verifiable indicators in evaluations of building energy performance. The research objective has two parts: to review, compare, and discuss (i) requirements and (ii) evaluation methods used to achieve energy performance of residential buildings in Sweden, Norway and Finland. The work in this thesis includes reviews of the requirements used in national building codes and passive house criteria to achieve building energy performance, of methods used to evaluate compliance with such requirements, and of methods used specifically to evaluate the indicator Envelope Air Tightness. The results show that different sets of indicators are used to achieve building energy performance in the studied building codes and passive house criteria. The methods used to evaluate compliance with requirements used to achieve building energy performance are also different, but calculation methods are generally more often used than measurement methods. The calculation- and measurement methods used are often simple. A methodology to analyze the deviation between predictions- and measurements of building energy performance (the performance gap) was developed, to investigate the effects of different evaluation methods on different indicators used to achieve building energy performance. The methodology was tested in a case-study. This study indicated that the choice of method affects which parts of the performance gap reflected in the indicators Supplied Energy (see Terminology), Net Energy (see Terminology), and Overall U-value. Among the reviewed methods to evaluate air tightness, the Fan/Blower Door Pressurization is well known and preferred by professionals in the field. The results in this thesis may be useful when choosing indicators and evaluation methods to achieve different objectives of improving building energy performance and in the quest towards comparable and verifiable indicators used to achieve building energy performance.Increasing Energy Efficiency in Buildings (IEEB)
