Johansson, Jan. "Cavern wall design principles." Licentiate thesis, KTH, Civil and Architectural Engineering, 2003. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-1631.
Full textAbstract:
This licentiate thesis deals with the design of lined rockcaverns used for the storage of gas under high pressures (20-25MPa). This storage technique has been developed in Swedenduring the last 20 years. The concept has been named LRC (LinedRock Cavern).
The goal of the research has been to develop a methodologyfor the design of the cavern wall so that it can fulfil thesafety demands put placed upon it by the society. To achievethis, an extensive knowledge about the properties of the wallmaterials, and how they interact, is required.
The proposed design methodology is based on the cavern wallbuild-up principles that have emerged during the many years ofdevelopment of the LRC concept. The cavern wall consists, inshort, of (from inside outwards): a gastight steel lining, asliding layer of bitumen, a reinforced concrete lining, ashotcrete layer and finally the rock mass.
In the thesis, a step-by-step approach is proposed toanalyse the deformations and strains that the cavern wall issubjected to as the rock caverns expands as a result of thepressurisation. The analysis begins with an assessment of thedeformation properties of the rock mass and proceeds with anestimation of the deformation in the most strained part of therock cavern. The analysis continues with an examination of howthe rock deformation is transmitted through the wall structure,ending in an assessment of the strain in the most strained partof the steel lining. The final step in the methodology is tocompare the calculated steel strain with the acceptable strain,derived from acceptable risk criteria or extracted fromrelevant codes. As an LRC storage is subjected to hundreds ofload cycles (with potentially high strain levels in the steellining) during its lifetime, the dimensioning load case is lowcycle fatigue.
The methodology is based on several assumptions regardingthe properties of the structural parts included in the cavernwall and how they react to the pressure load, both as singleparts and in interaction with adjacent structural parts. Theassumptions regard e.g. the deformation properties of the rockmass, the behaviour of the rock mass during repeatedhigh-pressure loading, the crack distributing effect of thereinforcement and the properties of the sliding layer.
Support for these assumptions has been gathered fromtheories, previous experiences and performed practical tests.The long concept development work has included numeroustechnical studies and tests, which have been used in thecreation of the design methodology. The experiences gained fromthe Pilot tests in Grängesberg have been especiallyvaluable to this end. A series of laboratory tests on themechanical properties of the sliding layer, for the load casein question, have been performed as part of this licentiatework.
The proposed design methodology for the cavern wall is basedon a probabilistic approach. This approach has been chosen forseveral reasons, among others because LRC is a new technologywithout established design practice and because a probabilisticview is a good way to manage the uncertainties, which in thepresent case originates from the stochastic nature of the rockmass. The properties of the rock mass vary within the volumeand are better described by an interval or a distributioninstead of a deterministic value.
The calculation tools used are in themselves rather simple.The basis is an elastoplastic analytical solution for thedeformation of the rock cavern during pressurisation. Thecalculations are performed as Monte Carlo simulations in aspreadsheet model. The choice of calculation tool was done fortwo main reasons, partly to get a lucid method where each stepin the process can be followed, partly because of limitationsin time and budget. However, a large number of FEM calculationshave been used, in addition to the observed behaviour of thePilot Plant, to verify and calibrate the model.
The proposed methodology shows one practicable way ofdesigning an LRC storage. The methodology has already beenapplied in the design of the worlds first large scale LRCstorage (the LRC Demo Plant at Skallen, near Halmstad insouth-western Sweden).
Areas where it is judged possible to improve or supplementthe proposed design methodology are:A thorough evaluation of the deformationbehaviour of the Demo Plant can be used to check the validityof the assumptions made. Depending on the outcome of such acheck, this might lead to a modification of the designmethodology.The sliding layer is of great importance for thestress and strain in the steel lining. It is urgent to continuethe development and testing of the sliding layer material andits properties.It should be examined if, and in which case how,the use of stochastic FEM analysis, asa calculation tool,could improve the handling of uncertainties in the designmethodology.

Tese de Doutoramento em Design, com a especialização em Design apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutor.ABSTRACT: This thesis is an exploratory study of moves and movements of the design discipline towards social and activist critical practices. It departs from a growing concern for design as a socially committed activity that has been around since the 1960s. The social turn, as we describe it, was a historical plea for designers to expand the nature and complexity of the problems addressed by design, moreover, to involve the users and stakeholders in designing processes. Turning to work with different sectors and diverse publics, the ‘social design’ movement emerged in opposition to the industrial and the commercial paradigms. As participatory and co-design approaches spread to general practice and for all kinds of purposes, social design became increasingly seen as a culture to represent a wider historical actualisation of the discipline. Still, in recent years, authors point to the difficulties of becoming socially engaged. Although literature on the ‘how of’ collaboration abounds i.e. the motivations, structure and techniques to involve others in design processes; it appears co-design entails ambiguous practices where designers often find themselves without a discipline. Struggles to craft a role for design in initiatives coordinated by networks of communities and institutions too often has led to actions imported from other fields hence the end of design. Coming from a background in graphic design, taking steps to become a social designer, we experienced how difficult it is to do away with the discipline. Specific gestures, actions and products in our social engagements that destabilized the visual communication design process also revealed visual communication design practiced in unknown or unexpected ways. Shifting the perspective to consider, beyond destabilization, it is indiscipline that happens to design in the encounter with others we articulated the question: what if choosing to become social is not to lose the discipline? This matter is worth to research because while social design became known for its risky participatory moves, some authors point to shifts in the politics of designing that have not yet been clarified. Through a mixed methodology based on action research and grounded theory we devised case studies to better describe, explain and explore, from a performative perspective and deeper anthropological stance, all that happens in co-design beyond exclusive attention to the design expert. While disclosing different social form-acts of social interaction within design, four images of indiscipline emerged. 1) IT’S ABOUT THE HOW, 2) DESIGN IS THE SITUATION, 3) BEGININGS NOT ENDS, and 4) DESIGN IS A LIVING THING, all point to different sides of the performative and politics turn that happens to design when it becomes social. Addressing the lack of discourse that does not treat the social as a irreducible complexity, this thesis develops a theory of design that reclaims the encounter with others as the space and possibility to grow the discipline in ways that even unexpected may also be radically social. The main conclusion is that indiscipline is not anti-design but an expansion of design possibilities in the encounter with others, which not yet seen or made visible can potentially represent moves from conventional practices towards critical socially engaged designing. Recommendations for future research are to expand the inventive and pedagogic potentials of indiscipline as a concept to understand the social turn and to practice becoming socially engaged in ways that are deemed better for others and ourselves. Another opening is to understand how indiscipline may be articulated in design education how and when students may be ready for design practice to become a more living thing.

Hashemi, Nezhad Ashrafi S. "Ethical principles for hospital design." Thesis, University of Liverpool, 2017. http://livrepository.liverpool.ac.uk/3022732/.
Full textAbstract:
The subject of this thesis is 'Ethical Principles for Hospital Design'. The mission of this research is to identify the ethical principles for hospital design in the form of a structured framework for ethical discourse about the medical environment. I think this thesis addresses a gap in the current literature, in which, there is not really an already existing structured framework for ethical discourse about the hospital environment. The ethical principles for hospital design can guide designers to identify their ethical duties toward users of the hospital environment (e.g. patients, staff, and visitors). For this sake, I will be engaging with literature that is critical of using the concept of dignity in biomedical contexts, as well as, Nussbaum's capability understanding of dignity. In the introductory chapter, I will explain my reasons for working on this subject and briefly introduce the content of each chapter. In the second chapter, I will discuss the concept of human dignity from the viewpoint of Kant. I will then consider the standpoint of Nussbaum in relation to the meaning and the theory of human dignity. In the third chapter, I will link the idea of human dignity to the notion of human entitlements in the hospital environment. In this regard, I will explain and develop the implications of human dignity in Nussbaum's thought and, accordingly, I will suggest a list of the entitlements of people in hospitals. Such a list of entitlements is the first part of the ethical method in hospital design which I call the dignity approach. The second part is addressed in the fourth chapter, in which I will suggest and elaborate upon three ethical principles; namely, design for vulnerability, design for healing, and design for reverence. These will form my proposed basic ethical principles of hospital design grounded in respect for human dignity and entitlements. Suggesting the dignity approach, I will, also, be critiquing and seeking to supplement in a certain way the influential Evidence-Based Design approach in hospital design. The last chapter will supply a conclusion of the arguments of this thesis and indicate some directions for future research.

Full textAbstract:
Interactive television (iTV) is an umbrella term used to cover the convergence of television with digital media technologies such as computers, personal video recorders, game consoles, and mobile devices, enabling user interactivity. Increasingly, viewers are moving away from a "lean back" model of viewing to a more active "lean forward" one. When fully realized on a widespread scale in the United States, our current experience of watching television will be dramatically transformed. Because iTV is a new medium in its own right, however, standards for iTV programming and interaction in the United States remain undefined.
This document identifies and articulates interaction design principles for interactive television programming in the United States. Chapter one presents a brief survey of the field as it stands in 2005. In chapters two and three, I categorize iTV by platforms and by persistent television genres, and present representative examples for each category. In chapter four, I provide an overview of existing design standards in related areas. Insights from chapters two, three, and four all serve to inform chapter five, in which I propose principles for iTV interaction design by looking closely at existing designs (both deployed and prototyped), conventions, and patterns of interaction. My analyses are rooted in visual culture and human-computer interaction design principles, and the design principles I offer are abstracted from the applications I analyze within this framework. Finally, in chapter six, I offer some conclusions and thoughts for future directions.

Full textAbstract:
As the use of mobile devices is increasing and the use of laptops and computers is decreasing it is becoming more important to design for better web usability across platforms. The established design principles for web design provide guidelines when designing and testing web usability. The principles, however, are not commonly used to evaluate and test the usability of mobile websites. This study seeks to examine how the usability of mobile and desktop websites is affected based on the adaption of established web design principles. The study is built upon an analytical framework where common keywords have been selected from a selection of established web design principles. This study takes on a qualitative approach with experimental features, using a heuristic evaluation, a usability study and an eye-tracking experiment. The study indicates that there is a connection between low adaption of certain keywords of web design principles and the usability of mobile and desktop websites, contributing to a deeper understanding of how adaption of design principles affect web usability across platforms.Användningen av mobila enheter har på senare tid ökat och användningen av bärbara datorer och stationära datorer har minskat. Det blir därför allt viktigare att designa mer användarvänliga hemsidor på olika plattformar. Etablerade design principer för webbdesign anger riktlinjer för design och test av webbanvändbarhet. Design principer används inte i en större utsträckning för att utvärdera användbarheten på mobila hemsidor, därför syftar denna studie till att undersöka hur användbarheten för mobilhemsidor påverkas utifrån att tillämpningen av design principer för webbdesign. Studien bygger på ett analytiskt ramverk där nyckelord har valts ut från ett antal etablerade webbdesign principer. Studien har ett kvalitativt tillvägagångssätt, med experimentella inslag. Studien har genomförts genom heuristik utvärdering, användbarhets studier och eye-tracking experiment. Studien indikerar att det finns en koppling mellan lägre nivåer av tillämpning av webbdesign principer och användbarheten på mobil- och datorsanpassade hemsidor. Denna studie bidrar till en djupare förståelse om hur anpassningen av design principer och dess påverkan av användbarheten på hemsidor över olika plattformar.

Full textAbstract:
Our nervous system, like most information processing systems, faces 4 fundamental physical constraints. It has to transmit information quickly (1. time) and reliably (2. noise) while keeping its energy consumption (3. energy) and size/weight (4. spatial scale) at a minimum, to support the behaviourally determined fitness of the organism. These constraints are likely to enforce trade-offs to be made in the evolution of the nervous system. Taking this view, I investigated myelinated and unmyelinated axons across systems and species. I developed user interfaces and simulation methods for the Modigliani stochastic simulation software, and made a number of findings highlighted in the following. Myelinated axons make up the majority of long-range connections in CNS and PNS. I derived size-dependent relationships for metabolic costs of action potentials in myelinated axons. The high density of sodium channels at Nodes of Ranvier set lower limits on myelinated axons' outer diameter (0.3 μm), which is 3-fold that for unmyelinated axons. In contrast, thin, unmyelinated axons make up most of the local (cortical) connectivity. Using a variety of axon models and detailed models of synaptic calcium dynamics and vesicle release, I showed that the waveform of action potentials undergoes random changes whilst traveling along thin unmyelinated axons. These fluctuations translate into synaptic response variability. The diameter of unmyelinated axons sets energetic limits to signalling, and I derived diameter-dependent relationships for the maximum rate of burst and sustained firing. The latter depends on the density of pumps and metabolic cost of action potentials, but is counter intuitively independent of axon diameter. My findings provide insights and scaling-relationships that relate the 4 fundamental design constraints for wiring brains. They allow us to quantitatively predict structure-function relationships, and form a basis for principled treatments of nerve disorders.

Full textAbstract:
Computers are valuable tools for a wide range of work tasks. A substantial limitation on their value, however, is the predominant focus on enhancing the work of individuals. This fails to account for the issues of collaboration that affect almost all work. Research into computer supported cooperative work (CSCW) aims to eliminate this deficiency, but the promise of computer systems for group work has not been met. This thesis presents four design principles that promote the development of successful groupware. The principles identify the particular problems encountered by groupware, and provide guidelines and strategies to avoid, overcome, or minimise their impact. Derived from several sources, the major influence on the principles development is an investigation into the relationship between factors affecting groupware failure. They are stimulated by observations of groupware use, and by design insights arising from the development of two groupware applications and their prototypes: Mona and TELEFREEK. Mona provides conversation-based email management. Several groupware applications allow similar functionality, but the design principles result in Mona using different mechanisms to achieve its user-support. TELEFREEK provides a platform for accessing computer-supported communication and collaboration facilities. It attends to the problems of initiating interaction, and supports an adaptable and extendible set of "social awareness" assistants. TELEFREEK offers a broader range of facilities than other groupware, and avoids the use of prohibitively high-bandwidth communication networks. TELEFREEK demonstrates that much can be achieved through current and widely accessible technology. Together, Mona and TELEFREEK forcefully demonstrate the use of the design principles, and substantiate the claim of their utility.

The main goal of this thesis is to explore how interior spaces in hotel designs can provide a less stressful environment and promote health and harmony by using Feng Shui Principles. It will first discuss the principles of Feng Shui and general hotel design, and then move on to demonstrate how the application of Feng Shui principles can be used to create a hotel environment that encourages health and harmony in its occupants. This project will demonstrate principles that not only can be applied to hotel space, but also can be practiced in any other interior space. This thesis, therefore, demonstrates new possibilities for how "care of the self" is delivered and received through design.

Full textAbstract:
Physically Interactive Games (PIGs) have emerged as a new game genre and
potential as an educational tool in classrooms. In PIGs, children are allowed to
interact with game environment and solving problems by using their bodily
movements and voices without using mouse or keyboard by being active physically
and cognitively. Designing PIGs is critical and difficult process because it is vital
that educational content and entertainment parts of a game should be balanced
properly considering interaction between children and game environment.
The current dissertation aims to explore principles of designing and
developing physically interactive educational games for children. Mainly, qualitative
data collection techniques were used in the study. Also, Reeves&rsquoDevelopment Research Model was administered under the Design-Based Research. Both Mathematics and Physical Education subjects were integrated within the game environments. Totally four physically interactive games were designed and developed. During the design and development phases, field experts, subject-matter experts and children&rsquo
s expectations, needs and recommendations were taken into account. During the development phase, 5 teachers with 3 Mathematics and 2 Physical Education teachers as subject matter experts participated to the study. Also, 10 v children with 5 boys and 5 girls participated to the design phase. In the implementation phase, 30 children with 17 boys and 13 girls participated in Pilot Implementation and 50 children with 27 boys and 23 girls participated to the Final Implementation phase. The study revealed that camera screen was the main deterministic factor in order to play physically interactive educational games properly. Girls and boys had different considerations about the developed games. The bigger camera screen physically interactive games had, the higher motivation children had during gameplay. At the end of the study, design principles of physically interactive educational games were defined.

Full textAbstract:
In critical scenarios such as power plant management or air traffic control, human errors can have critical consequences. It is therefore a key concern that operators have a clear understanding of the situation at hand. Providing high situation awareness when designing interactive systems for these users is an important concern: many factors need to be considered to avoid hazardous conditions. Situation Awareness Oriented Design (SAOD) is a design methodology that makes use of design principles as tools to guide designers in creating or adapting systems for achieving outstanding situation awareness. This study focuses on what problems arise when using a selection of SAOD principles as the principal tool in the design process. The research was carried out using a research-through- design methodology, where SAOD principles were employed for the design of D4SH, an interactive overview system in the maritime scope of remote service centres. The results indicate four problems that might occur in the design process by using these principles. First, principles did not help in making design decisions. Second, at times they indirectly conflicted with one another when having to make a choice. Third, grounded user analysis was needed for the correct use of the principles. Fourth, in some instances principles highlighted a problem without offering a desirable solution. Therefore, the validity of principles in the various phases of design is questioned, and some implications of using the principles as a complementary design tool are suggested. In conclusion, it is argued that the problems encountered are a necessary trade-off for having a powerful framework that can be successfully used in many contexts for situation awareness.I kritiska situationer, såsom kraftverkshantering eller flyplansledning, kan mänskliga fel ha allvarliga konsekvenser. Det är därför viktigt att tekniska operatörer har en god uppfattning av den aktuella situationen. En nyckelfråga då interaktiva system för dessa användare designas är därför att tillhandahålla en hög situationsmedvetenhet, där många faktorer beaktas för att undvika farliga situationer. Situation Awareness Oriented Design (SAOD) är en metodik som använder designprinciper som vägledning då system anpassas för att tillhandahålla god situationsmedvetenhet. I denna studie undersöks vilka problem som uppstår när man använder ett urval av SAOD-principer som det främsta verktyget i designprocessen. Forskningen genomfördes med hjälp av en designmetodik där SAOD-principer användes för att utforma D4SH, ett interaktivt översiktsystem för servicecenter inom den marina sektorn. Studiens resultat indikerar fyra problem som kan uppstå genom att använda dessa principer i en designprocess. Först och främst upplevdes principerna inte underlätta designbeslut. För det andra var principerna indirekt motsägelsefulla då ett beslut skulle fattas. För det tredje behövdes en grundläggande användaranalys för att använda principerna korrekt. För det fjärde belyste principerna i vissa lägen problem utan att erbjuda en önskvärd lösning. Baserat på detta ifrågasätts principernas giltighet och konsekvenser av att använda principerna som ett kompletterande designverktyg föreslås. Slutsatsen av studien hävdar att problemen som identifieras är en nödvändig kompromiss för att kunna erbjuda en kraftfull ram, som framgångsrikt kan användas i många sammanhang för att tillhandahålla situationsmedvetenhet.

In this thesis, the issue of airport terminal design is examined from a novel perspective: that of the passenger rather than the airport operator. A qualitative approach, based on interviews with 199 passengers at Brisbane International Terminal was adopted.
The outcomes of this research make the following three key contributions to existing knowledge: (i) identification of a paradox in the Level of Service metrics, (ii) development of a conceptual model of passenger experience and six design principles and (iii) contribution towards advancing the theoretical knowledge about passengers and their experience in airport terminals.

Mawle, Richard G. "Integration of EcoDesign principles within small product design consultancies." Thesis, Loughborough University, 2018. https://dspace.lboro.ac.uk/2134/33186.
Full textAbstract:
Each year in the UK (United Kingdom) hundreds of millions of consumer products are sold, leading to many millions of tonnes of waste being buried or burned annually. While there are many large businesses that produce consumer products, in the UK small product design consultancies (SDCs) make up approximately half of all employed designers. This thesis outlines an investigation into the absence of an EcoDesign agenda in product design briefs and how this might be changed in the future. In order to best establish the theoretical basis of the research, a comprehensive literature review was conducted into the practice of product designers, their relationship to society and the wider environment. In addition, existing tools and resources purporting to support product designers, with the implementation of EcoDesign projects, were analysed to understand the challenges associated with their design. Following this review, and the development of relevant research questions, a series of semi-structured in-depth interviews were conducted to understand SDCs better, how these organisations conduct their business, and how familiar they are with EcoDesign. A series of semi-structured in-depth interviews were conducted with 26 participants from 22 different consultancies. As a result of these interviews, a greater understanding of the barriers and drivers SDCs face in the practice of EcoDesign was established. This led to the creation of d.eco a web-based resource, to facilitate the implementation of EcoDesign principles in SDCs. This resource was evaluated in the final stage of the research. The majority of product designers had an awareness of EcoDesign and considered that they would be able to use their skills to find the information necessary to create products with a reduced environmental footprint. A significant barrier was that EcoDesign principles could only be legitimately applied when the design brief required their use. However, briefs are not created solely by clients; they were found to be much more collaborative, thus offering designers an opportunity to influence their own briefs. So, the role of an EcoDesign resource is less about assisting the design process, like most existing tools, and more to do with the providing designers with a wellspring of inspiration. However, the resource stimulates more than just creativity. It also provides peer recommended examples of existing EcoDesign products, materials and processes, facilitating the long-term absorption of relevant information. By presenting relevant material, in an appropriate way, designers can be more confident when including EcoDesign criteria and associated principles within their briefs.

Although Internet booking system has reached its peak in the recent years many previous researches say there is always a growing interest in the role and nature of design in HCI principles. Small difference can create a large impact in the business of Internet booking system. The future of any online booking system will be heavily depended on how easy and how friendly the system is designed. In our thesis, we are going to suggest what aspects of usability principles are important in making the user interface of current flight booking systems to reach a high degree of usability. For the above purpose we will find usability flaws in the current user interface design of flight booking systems and highlight the potential factors or aspects that make user interface more acceptable to users. To reach this purpose we will use a case study and analyze using an explanation building technique. The empirical data was collected through satisfaction questionnaire which was based on nine “preset tasks” which are designed depending on various usability principles. In our thesis, we will create an understanding on the aspects of usability principles used to make a user interface more acceptable to the users. This understanding will lead future researches in the betterment of interface design of flight booking system.

This thesis presents a theoretical foundation and methodology for designing novel 4-coil high frequency coreless power transformers from first principles via lumped equivalent circuit models. The procedure is applied to construct a design for 100W transformer with an S21 parameter value of .96. Using MATLAB and LTspice, simulation tools have been developed to produce accurate predictions of inductance, resistance, coupling coefficients, and S21 parameter values for an ensemble of coil models. These theoretical calculations have been employed for spiral and cylindrical coils and have been validated with numerous constructed experimental designs. The utility uses a first principles approach and derives these calculations directly from the physical parameters and relative positions of the coils. Simulation outputs greatly aid the engineering task of designing an efficient coreless power transformer.

The demand for high power proton beams is at an all time high. The global community has identified many applications ranging from spallation sources, material irradiation facilities and secondary beams factories to accelerator driven systems for energy production, transmutation of waste or production of tritium. The typical path to high power beams involves the use of a linac at least in the lower energy stages. For high intensity, high power operation, significant developments are needed particularly in the linac section and the front end of the machine. Consequently, this thesis brings original contributions in tackling several limiting aspects to do with two major pillars of high power operation in linacs: energy and intensity. One of the major decisions in any linac design concerns the choice of normal accelerating structures. The general aim of every designer is to find the optimal path to the final energy without compromising the beam quality or increasing excessively the structure complexity. In the absence of a much needed comparative assessment of accelerating cavities, this choice was often made based on available local expertise rather than solid reasoning. This problem is tackled at length in two chapters of this thesis in which a framework is created for a methodical examination of available structures. The result is the first systematic analysis of normal conducting structures for proton acceleration which includes beam dynamics, electromagnetic, mechanical, thermal and vacuum aspects of cavity design. On the intensity side, several innovative developments have arisen through involvement in the Front End Test Stand Project (FETS) and the ISIS linac upgrade efforts. Beam dynamics studies for the Medium Energy Beam Transport line (MEBT) of FETS, as well as an analysis of several other MEBT designs for existing international projects, highlighted the difficulty in reducing beam loss and emittance growth in high current MEBT lines incorporating beam choppers. Through end-to-end tracking studies, it was shown that the initial beam quality produced in the MEBT will heavily influence the emittance evolution, halo development and beam loss in subsequent structures. As a result, a novel distributed MEBT design is proposed as an alternative, allowing better matching and chopping as well as higher intensity, lossless operation. Further downstream, the beam quality is not only affected by initial mismatch and MEBT beam quality, but by the choice of operating points as well. Theoretical work developed over the last two decades indicate that safe tunes outside conventional equipartitioning limits can be found, but the lack of experimental verification remains a problem. This problem was tackled through an experimental campaign at J-PARC, where for the first time emittance exchange driven by the kz/kt = 2 resonance was measured in a linac with emittance ratios close to 1. Finally, these principles are applied to the design of a future upgrade of the ISIS linac. Three linac options have been developed accelerating the beam to 100, 180 and 800 MeV opening the possibility of MW-level operation in ISIS.

Today's smartphones are capable of accomplishing far more advanced tasks than reading emails. With the modern framework TensorFlow, visual object recognition becomes possible using smartphone resources. This thesis shows that the main challenge does not lie in developing an artifact which performs visual object recognition. Instead, the main challenge lies in developing an ecosystem which allows for continuous improvement of the system’s ability to accomplish the given task without laborious and inefficient data collection. This thesis presents four design principles which contribute to an efficient ecosystem with quick initiation of new object classes and efficient data collection which is used to continuously improve the system’s ability to recognize smart meters in varying environments in an automated fashion.

Full textAbstract:
Software reuse can occur in various places during the software development cycle. Reuse of existing source code is the most commonly practiced form of software reuse. One of the key requirements for software reuse is readability, thus the interest in the use of data abstraction, inheritance, modularity, and aspects of the visible portion of module specifications. This research analyzed the contents of software reuse libraries to answer the basic question of what makes a good reusable software component. The approach taken was to measure and analyze various software metrics as mapped to design characteristics. A related research question investigated the change in the design principles over time. This was measured by comparing sets of Ada reuse libraries categorized into two time periods. It was discovered that recently developed Ada reuse components scored better on readability than earlier developed components. A benefit of this research has been the development of a set of "design for reuse" guidelines. These guidelines address coding practices as well as design principles for an Ada implementation. C++ software reuse libraries were also analyzed to determine if design principles can be applied in a language independent fashion. This research used cyclomatic complexity metrics, software science metrics, and traditional static code metrics to measure design features. This research provides at least three original contributions. First it collects empirical data about existing reuse libraries. Second, it develops a readability measure for software libraries which can aid in comparing libraries. And third, this research developed a set of coding and design guidelines for developers of reusable software. Future research can investigate how design principles for C++ change over time. Another topic for research is the investigation of systems employing reused components to determine which libraries are more successfully used than others.

Full textAbstract:
As a summary, this work attempts to explore and uncovered design principles of certain dynamics of cellular networks by combining evolution in silico with rule-based modelling approach. Biological systems exhibit complex dynamics, due to the complex interactions in the intra- and inter- cellular biochemical reaction networks. For instance, signalling networks are composed of many enzymes and scaffolding proteins which have combinatorial interactions. These complex systems often generate response dynamics that are essential for correct decision-makings in cells. Especially, these complex interactions are results of long term of evolutionary process. With such evolutionary complexity, systems biologists aim to decipher the structure and dynamics of signalling and regulatory networks underpinning cellular responses; synthetic biologists can use this insight to alter existing networks or engineer de novo ones. Both tasks will benefit from an understanding of which structural and dynamic features of networks can emerge from evolutionary processes, through which intermediary steps these arise, and whether they embody general design principles. As natural evolution at the level of network dynamics is difficult to study, in silico evolution of network models can provide important insights. However, current tools used for in silico evolution of network dynamics are limited to ad hoc computer simulations and models. In my PhD study, with collaborators I construct the BioJazz, an extendable, user-friendly tool for simulating the evolution of dynamic biochemical networks. Unlike previous tools for in silico evolution, BioJazz allows for evolution of cellular networks with theoretically unbounded complexity by combining rule-based modelling with an encoding of networks that is akin to a genome. BioJazz can be used to implement biologically realistic selective pressures, and allows exploration of the space of network architectures and dynamics that implement prescribed physiological functions. It is provided as an open-source tool to facilitate its further development and use. I use this tool to explore the possible biochemical designs for signalling networks displaying ultrasensitive and adaptive response dynamics. By running evolutionary simulations mimicking different biochemical scenarios, we find that enzyme sequestration emerges as a key biochemical mechanism for both dynamics. Detailed analysis of these evolved networks revealed that enzyme sequestration enables both ultrasensitive and adaptive response dynamics. I verified this proposition by designing a generic model of a signalling cycle, featuring two enzymes and a sequestering (scaffold) protein. This simple system is capable of displaying both ultrasensitive and adaptive response dynamics, even more interestingly modulating the system switching between two response dynamics through perturbing the scaffold protein. These results show that enzyme sequestration can be exploited by evolution so to generate diverse response dynamics in signalling networks. From evolutionary simulations towards ultrasensitivity, bistable dynamics emerged as an alternative solution. On one hand, inspired by such results I used the fitness function as an objective function combined with different constraints to design and optimise bistable signalling networks with completely new structure and mechanism. Studying designed bistable signalling network explicates how such bistable network can be experimentally implemented. On the other hand, from studying the evolved bistable networks allosteric enzymes catalysing futile cycles appear to be a new mechanism of bistability in signalling networks. Furthermore, one of the smallest bistable signalling motifs is derived. This motif is composed of one kinase protein with two distinct conformational states and one substrate subject to phosphorylation by the kinase and auto-dephosphorylation reactions. The sufficient and necessary condition on parameters, with which the signalling motif displays bistable response dynamics, is analytically defined. By expanding the systems with more kinases, unlimited multistability emerges with potentials of implementing complex logic gates and cell state transitions. Further exploring the discovered and natural signalling networks implies shared design patterns. Motivated by searching structural boundaries between monostationary and multistationary networks, I performed algorithmic searching of multistationary signalling networks intending to find the sufficient structural conditions for multistationarity in signalling networks.

Full textAbstract:
Sustainability entrepreneurship is the process of creating new enterprises that survive and thrive by contributing to human wellbeing and the functioning of ecological systems. This study is an investigation of the principles, processes, and paradigms of successful sustainability entrepreneurship. Based on a critical realist perspective, a multiple, embedded case study strategy was used to explore the unique design histories of successful sustainabilitydriven enterprises in four different regions and industries - one each in Europe, North America, East Africa, and Asia-Pacific, and in the marketing and finance, hospitality, training, and export-import-wholesaling sectors. Qualitative data consisting of interviews, documents, and observations from site visits were collected and analysed using combined comparative and narrative analyses. These methods enabled the actor logics that guided the unfolding enterprise design process to be identified and described. Institutional theory was used to educe the implications of these logics for the character and performance of emerging enterprises. The first of three principal findings of this study is a cognitive model of sustainability entrepreneurship that specifies five design principles that guide problem solving. The second principal finding is a process model of sustainability entrepreneurship that demonstrates the way these design principles and the underpinning values become embedded in the enterprises' formal and informal structures, allowing the enterprises to maintain their intended purposes and character while necessarily evolving to ensure survival into the future. The third principal outcome is the proposition that this distinct approach to enterprise design represents the emergence of a new organising paradigm that eschews the dualistic divide between'opportunistic' business and 'altruistic' charity in favour of a new logic based on the coproduction of multiple benefit streams through the perpetuation of human and natural resource quality.

Full textAbstract:
We see this world rich with culture, emotion, and human connections. The human built world can afford a sense of beauty, sublimity, and resonance, and through our advancements in technology also bringing the advancements in society. At the center of these advancements are interactions, conversations, connections, collaborations, and relationships, within and across multiple disciplines, with and without technology. For the last decades, as the computer technologies have been developing, the importance of human-computer systems interaction problems are also growing with the passage of time. This is not only because of the computer systems performance and characteristics have been improved, but also due to the growing number of computer users and of their expectations about general computer systems capabilities as universal tools for human work and life facilitation. Interface design is important for several reasons and the current growth of the different web applications are characterized by an increasing availability of online different services or products trading and different search facilities like flight search web sites, provided by most commercial airlines. In this study we will therefore create an understanding of the most important interaction design principles for the designers of online booking systems. The research methodology used in the research is design and creation. The method components used in this study are documents and interviews. The theoretical study has identified some important aspects covering the human computer interaction, usability of interactive interface, user feedback and the user-centered design approach for the development of such online booking systems. These aspects have been verified through the three interviews with the interviewees having different experience levels. The result shows that the interaction design is really important in designing of interactive online booking system. Therefore, the designers of such systems need to have an understanding of the most important design principles like the usability and functionality of the system, the approach should be iterative in design, provide proper feedback, minimum steps in booking process, risk management, and user-centered approach should be included in your design principles. It is also important for the designers of online booking systems to be aware of the usability factor of the system. The cognitive psychology is also vital for designers to understand how users think and perceive things. Designers need to have a good balance between context and graphics of the interface of such systems. The result also has been shown in the design of prototype with the most important interaction design principles and other factors.Program: Magisterutbildning i informatik

Fox, Stephen John. "Application of design for manufacture principles to building design and construction." Thesis, Sheffield Hallam University, 2001. http://shura.shu.ac.uk/19207/.
Full textAbstract:
The aim of this thesis is to answer the two research questions: how can design for manufacture be applied during building component design and building design?; and how can the application of design for manufacture be successful in improving the productivity and quality of building component production and building construction? These two questions emerged during exploratory research focused on the use of design to improve construction industry productivity and quality. Subsequent review of manufacturing literature revealed that the two key principles of design for manufacture are standard production design improvement rules and standard production design evaluation metrics. Review of construction literature, and a survey involving over one hundred and fifty industry practitioners, revealed that, whilst rules and metrics for building components and buildings do not currently exist, there are no fundamental reasons why they could not be developed and applied successfully. These findings led to the generation of the research hypothesis: design for manufacture principles can be applied successfully to building components and buildings. The research hypothesis was tested by two interventions, action research within a private business which manufactures and installs building components, and a case study with a multi-national company which designs and constructs buildings. These interventions resulted in significant business benefits. Further, they confirmed that it is both technically feasible and economically viable to apply rules and metrics to building component design and building design, and that doing so can improve the productivity and quality of building component production and building construction. Following analysis of research findings, strategic plans were developed for the successful application of rules and metrics. These were validated through interviews with senior construction industry practitioners. Contributions to knowledge include the strategic plans for successful application of rules and metrics. These cover the full range of organisations working in the construction industry and, together with the detailed descriptions of the interventions, offer practical guidance for industry practitioners seeking to improve productivity and quality. The research also makes a contribution in the area of research methodology. It has shown that threats to research validity in the construction industry can be counteracted by applying a quasi-experimental perspective to action research interventions and case studies.

Full textAbstract:
The ubiquitous enzyme dUTPase hydrolyzes dUTP into dUMP and pyrophosphate, preventing DNA fragmentation and cell death due to accumulation of dUTP. Inhibitors of dUTPase could serve as drugs in the treatment of cancers and infectious diseases. This thesis presents five studies. A mutational study on the Escherichia coli dUTPase (S72A) provides new insights about the catalytic principles of the homotrimeric dUTPases. A model is presented in which transition state formation is associated with a rotation of the conserved Ser72 side chain. The model can explain the strict order of deamination and hydrolysis catalyzed by the bifunctional dCTP deaminase:dUTPases. The S72A/D90N double mutant is currently investigated. Preliminary data indicate that this form preserves the binding properties of the S72A mutant but is completely inactive, making it attractive for structural studies. In the remaining studies we compare the binding of substrate analogues to the human, the E. coli and the equine infectious anemia virus (EIAV) homotrimeric dUTPases. One study concerns 2´,3´-dideoxy-UTP (ddUTP) and shows that removal of the 3´-hydroxyl group increases KM, ten times with the cellular dUTPases and fifty times with the viral dUTPase, but does not affect kcat with any of these enzymes. Another study concerns the inhibitory effects of 3´-azido-2´,3´-dideoxy-UTP. This derivative binds to the bacterial dUTPase but not to the other forms making it a potential lead for the development of antibacterial dUTPase inhibitors. Yet another study investigates two uracil derivatives. Both compounds are found to inhibit the human, the bacterial but not the viral dUTPase. The inhibition is shown to be competitive.

Frameworks have been used since the early eighties. Now that frameworks are becoming increasingly popular, several problems are surfacing. Those problems can be categorized into evolution problems (i.e. problems with changes over time) and composition problems (i.e. problems that occur when more than one framework is used in an application). This master thesis focusses on preventing these problems in an early stage in the development of a framework. Guidelines for building OO Frameworks are presented and the guidelines are tried out in the domain of communication protocols.

Full textAbstract:
Harmony is a major theme in Chinese culture. It is reflected in many forms, e.g. painting and garden design. However, calligraphy gives a straight forward insight into harmony in two dimensions. The main hypothesis was that the principles for building a harmonious calligraphic character could be converted from holistic to deductive and computable ones. These could then be applied to the design of harmonious screen interfaces, which would give visual pleasure. The first aim was to investigate and discover the quantifiable features of harmony in Chinese regular script calligraphy. Calligraphy has been associated in China with harmony and elegance for over 1500 years. There are features that are commonly accepted to establish harmony which can be quantified. However, the principles of Chinese calligraphy are embedded within Chinese culture. Direct translation does not convey the meaning. An extensive study was made of the literature on Chinese calligraphy and a practical exploration of characters was made. This resulted in a small number of principles which were needed to be satisfied for the character to appear harmonious. These were tested on several groups of participants. These principles were then converted into a mathematical form for Chinese regular script calligraphy, and for application to harmonious screen interface design. The mathematical forms were then tested on both Chinese regular script calligraphy and also on interface designs with groups of participants. Finally, an application for comparing harmony in Chinese calligraphic characters and interface designs was created. The “Harmony” application can be used to calculate how a Chinese calligraphic character or an interface design satisfies the principles of harmony and it can give an indication of how harmonious they are.

Today multi-touch technology is the basis for many new techniques designed to improveinteractions with computers and mobile devices. It seems that multi-touch screen interfacemakes the user handling very natural in the sense that there is no need for a manual in how tointeract with the object on the screen.The aim with this paper is to establish a fundamental set of design principles intendedspecifically for large multi-touch interfaces. To reach this goal we have implemented a coupleof sub-goals beforehand:It was essential that we acquired a good understanding of the current state of the multi-touchinterface and the different implementations that exist today. To make this possible weconstructed a multi-touch display, "Rosie". Knowing how the hardware is produced today willhelp us understand the limitations and also the possibilities of the design implementationstoday and in the future.We also needed to devise a sound interaction design process that conveys the moderndesigners work. During this design process four methods were implemented that gave usdeeper understanding how to reach the result in this paper (design principles). The methodsare: Qualitative conceptualisation, Qualitative user-testing, Participatory design, and Iterativeprototyping. Doing these methods we gained knowledge through the process and experienceof for example, building, running workshops, doing video-prototypes and etc. Creative designwas very relevant in our design process.The result in this paper is a foundation for a set of design principles with relevance for multitouchinterfaces and a interesting design process for developing multi-touch applications.

The results revealed that the common menu design generatedhigher scores in usability than the interface designed through game design principles but therewas no significant difference in game feel between the prototypes. However, when dividing gamefeel into questions regarding usability and aesthetics a clear difference between the twoprototypes could be determined where the prototype designed through game design principlesdisplays a trend to score higher in aesthetics than the traditional UI. This could be strengthenedthrough optional comments from the participants where 6 used the word “fun” to describe thegame design prototype while the traditional UI design were described with words such as“functional” “intuitive” “straightforward” “easy to use” and “felt more like a chore”.

Full textAbstract:
At present, construction is one of the most destructive, energy consuming and material wasting industries. The current linear system cannot last, and to change anything, we need to redesign the system and our way of thinking. In my thesis, I will explain the theory behind a circular economy and how it could be applied to building, as well as discuss waste issues and material sources. Deconstruction is also a big polluter, and one solution to combat that problem would be to design buildings to be readily disassembled. The aim of this project is to bring awareness about the subject of sustainable design in a modern context and gather this information into one place. Many ideas presented are ones that have been around for as long as people have built buildings, such as material scarcity, resource efficiency and reusing existing materials while reducing waste. Some ecobuilding projects that have successfully implemented these ideas will be presented. In the conclusion, I will present certain concrete ideas and methods for bringing about circular thinking into the built environment. A good starting point would be to decide whether a building needs to be demolished, if so, can the elements be reused or recycled, or if designing a new build with renewable raw materials is the best optionYhteiskunnassamme rakennusalla kulutetaan nykyään eniten energiaa ja haaskataan materiaaleja. Lineaarinen talous ei kestä nykyistä toimintatapaamme ja muutoksia saamme aikaan vain muuttamalla järjestelmää ja ajattelutapojamme. Diplomityössäni käsittelen kiertotalouden teoriaa ja sen hyödyntämistä rakentamisessa, sekä pohdin jäteongelmia sekä materiaalilähteitä. Myös purkutyö on rakentamisessa suuri saastuttaja ja siihen esitän ratkaisuksi rakennusten suunnittelemista purettaviksi. Diplomityöni tavoitteena on lisästä tietoisuutta kestävän suunnittelun aiheesta (nykyhetken viitekehyksessä) ja koota nämä tiedot yhteen. Monissa esittämistäni konsepteissa hyödynnetään olemassa olevia ideoita, kuten materiaalien saatavuutta ja uudelleenkäyttöä sekä jätteenhallintaa, mutta oleellista on kuinka kokonaisvaltaisesti niitä käytämme. Esimerkkiprojektien avulla havainnollistan konseptien sovellutuksia käytännössä. Lopuksi ehdotan käytännön esimerkein miten kestäviä suunnitteluideoita voi käyttää rakennetussa ympäristössä. Rakentamisessa hyvänä lähtökohtana voi pitää, että rakennusten tulisi olla purettavia, kierrätettäviä ja että uusissa rakennuksissa käytettäisiin uusiutuvia raaka-aineita

DNA origami is a particularly versatile method to achieve complex molecular architectures. However, the rules for designing scaffolded DNA origami have not been well-formalized, which hinders both the investigation of characteristics of well- and poorly-folded structures as well as the participation of a larger scientific audience in DNA nanotechnology. In my thesis work, a fully automatic inverse design procedure DAEDALUS (DNA Origami Sequence Design Algorithm for User-defined Structures) has been developed that programs arbitrary wireframe DNA assemblies based on an input wireframe mesh without reliance on user feedback. This general, top-down strategy is able to design nearly arbitrary DNA architectures, routing the scaffold strand using a spanning tree algorithm and adding staple strands in a prescribed manner. The wireframe nanoparticles produced can use antiparallel crossover (DX) motifs, for robust selfassembly, parallel paranemic crossover (PX) motifs, for staple-free self-assembly, or a hybrid of the two, to minimize the number of staples required for folding to the ones necessary for functionalization. The thermodynamics of the self-assembly of these wireframe structures, and the effects of scaffold and staple routing, are investigated using quantitative PCR and FRET measurements, tracking fluorescence to elucidate global and local folding events. The framework developed should enable the broad participation of nonexperts in this powerful molecular design paradigm and set the foundation for further predictive models of DNA self-assembly.

The aging population is increasing at an unprecedented rate, and with it, the number of older adults that decide to age in place. Some public and private efforts have been made in order to better understand the mobility and physical needs of older adults in home environments. However, most of these efforts have missed a holistic definition of home and how the human dwelling is influenced by aging. This thesis is composed of three studies: a national survey, a series of in-home interviews, and an intergenerational workshop. The overall objective of these studies was to understand how older adults live and move within their homes, as well as what their emotional and functional expectations of their homes are. The outcome of this work is a set of principles and recommendations that design professionals can use when designing home environments or home-related products. These principles and recommendations are meant to serve as a guide to approach a project with the right mindset-a mindset that augments empathy and understanding for older adults, and that challenges the preconceptions of what a home is and what it should do for us as we age.

`FRACTION, an investigation on principles of functional design and its expressive potential´ is dealing with the interaction between the body, the worn garment and the closer space around it, in the context of the three being individual functional systems. Based on my findings, I am questioning the existing paradigms for a functional expression with the aim of generating an outlook for a possible development of what can be considered a functional visual. How much function can an expression contain and how much expression can still be considered functional?Revisiting the historic context of functional design, not garment construction, profound thoughts on aesthetics and function as well as the current status of the branch, this article is aiming for a more holistic view on functional creation and fashion design. Based on this theoretical background ten outfits got developed. All of them serve as a conceptual proposal of what the findings could mean in reality.Program: Konstnärligt masterprogram i mode- och textildesign med inriktning mot modedesign eller textildesign

The Application of Traditional Chinese Aesthetic Principles to Contemporary International Design. This is a submission by publication consisting of 13 major design projects and an accompanying research report. China is undergoing phenomenal economic growth that is having a major impact on the social and cultural development of the Republic. Accompanying the growth is an unprecedented urbanisation of the population and expansion of the cities. This has meant an explosion in the building industries. At the same time China is moving towards the central position in the global economy that also has huge cultural implications. This is the context in which I have pursued my professional practice as an interior and architectural designer. Some of the questions I have been attempting to address through my practice arise directly out of this context. In the fast expansion of the field of interior design that has accompanied this growth it is vital that Chinese designers are aware of the cultural context of their work. Is it possible for Chinese designers working in the developing international context of contemporary design projects in China to make a unique contribution to the field that is specifically Chinese? This presentation of my practice will provide a cohesive argument for an approach to design in the international arena that remains specific to the cultural and temporal context of its origins. I will specifically demonstrate solutions I have found to the application of ancient Chinese aesthetic principles to contemporary international design problems. As practice-based research I have given much thought to the methodologies I have employed. I will provide a detailed outline of these 'action' research methodologies and definitions of the types of knowledge employed in the following report. The visual evidence is also accompanied by descriptions of the projects including the briefs, design solutions and specific Chinese characteristics. The presentation of my practice in this form provides evidence of the ways in which cultural specificity can be maintained within the international design arena and makes a meaningful contribution to debates and knowledge in the area of cultural diversity and design.
