Full textAbstract:
High Tc superconductors are enabling in the generation of extremely high magnetic fields. Flux pumping is a promising technology which can be used to operate HTS magnets without significant loss. In this decade, several HTS flux pumps based on travelling magnetic waves have been developed, yet their physics is still unclear. This thesis established a framework in the area of flux pumping for HTS coils. It revealed the underlying physics of existing travelling wave flux pumps, which is an important theoretical contribution. Based on the thorough understanding of flux pumping mechanism, the author proposed two novel types of flux pumps. The new inventions make flux pumping much easier, more controllable, and much less energy consuming. These flux pumps may promote the future applications of HTS magnets. This thesis can be a guidebook for researchers and engineers in developing flux pumps.

Full textAbstract:
In recent years power generation from renewable energy has grown substantially both in South Africa and around the world. This growth is set to continue as there is more pressure to reduce the burning of fossil fuels. However, renewable energy power generation suffers from unpredictability, which causes problems when it comes to managing power grids. Concentrated Solar Power (CSP) plants offer a practical solution to store power in the form of thermal energy storage (TES). Thus, the plant can run when there is no solar energy available, leading to a more stable power supply. Unfortunately, CSP plants cost more than other renewables such as photovoltaic and wind power. Thus, there is a need for research into how to bring down the cost of CSP plants. One of the most proven types of CSP is the parabolic trough plant. The most recent innovation is to try and use molten salt as the heat transfer fluid which would reduce the cost of the plant. However, this new technology has not been implemented on a full scale CSP plant and little testing has been done to prove the technology. The HPS2 is a test facility aimed at testing the use of molten salt as a heat transfer fluid (HTF). This test facility, located in Evora Portugal, is being developed by an international consortium led by the German DLR institute of Solar Research. It is one of the first test facilities of its kind where experiments will be conducted to demonstrate the validity of using molten salt as a HTF and a storage medium in a parabolic trough CSP plant. The HPS2 test facility is not yet operational and there is a need for a dynamic thermofluid process model to better understand and predict both its steady state and transient operational behaviour. This dissertation reports on the development of such a dynamic thermofluid process model and the results obtained from it. The process model developed primarily focuses on the steam cycle with the TES incorporated into the model. The physical geometry of each of the components are employed to construct discretized elements for which the conservation of mass, energy, and momentum are applied in a one-dimensional network approach. The economizer and evaporator combined has a helical coil geometry and uses molten salt as a heat transfer fluid, which is unique. Thus, correlations had to be adjusted for the flow characteristics found in the economizer/evaporator. Results from the steady state simulations of the steam cycle show that the molten salt mass flowrate through the steam generation system will have to be reduced from the initially expected value to meet operational requirements. Results of the dynamic simulations show that the test facility will be able to produce a constant power supply despite transient solar conditions and highlights key dynamic responses for operators to be aware of.

Full textAbstract:
In recent years, there has been an upsurge in medical research assessing the therapeutic benefits of probiotic bacteria and growing commercial interest in food fortification with these bacteria. Probiotic bacteria such as L. acidophilus are known to be predominant Lactobacilli species in the intestinal tract of healthy humans and suggested to provide clinical health benefits such as enhancement of immunity against intestinal infections, prevention of diarrhea and hypercholesterolaemia and improvement in lactose utilization. Many studies have demonstrated the possibility of incorporating probiotic bacteria in an ice cream matrix and shown its viability can be maintained throughout the shelf life of the ice cream. However, there is limited information about the protective effect of ice cream on viability of incorporated probiotic bacteria during simulated gastric digestion using an in vitro dynamic model stomach.
In phase one of this study, a preliminary study was conducted to determine the effect of air addition on the viability of L. acidophilus La-5. This was done by manufacturing low fat (4%) non-fermented ice cream mix supplemented with L. acidophilus La-5 to yield an initial population of 107cfu/g. The mix was processed with 60% and 100% overrun (OR) and stored at -10ᵒC for 90 days. The effect of air addition at different levels was tested post freezing and every 30 days throughout its shelf life of 90 days. The results showed less than one log reduction in the viable counts of L. acidophilus La-5 for both samples incorporated with 60% and 100% OR after freezing and the number of viable cells did not differ significantly (p>0.05) from day 1 to day 90.
In phase two of this study, a 22 full factorial experimental design was used to evaluate whether the viscous nature of ice cream mix plays an important role in improving the survivability of L. acidophilus La-5 during simulated digestion against low pH and presence of mechanical shear and to determine whether initial inoculation level has any effect on the viability of L. acidophilus La-5 at the end of 2 hr simulated digestion. Non-fermented low fat (5%) ice cream mixes with high and low viscosity were produced by changing the amount of stabilizer/emulsifier blend and each of the two mixes were supplemented with two levels of L. acidophilus La-5 to obtain an initial population of 108cfu/g and 106cfu/g before freezing. These mixes were frozen with 60% overrun. The ice cream samples were digested for 2 hr in an in vitro model stomach called Human Gastric Simulator (HGS). This model included factors such as gastric secretions, mechanical shearing due to peristaltic contractions and temperature and pH control. No significant effect (p>0.05) of different levels of viscosity on the survivability of L. acidophilus La-5 was found during and at the end of 2 hr simulated in vitro digestion, irrespective of the difference in initial inoculation level. The initial supplementation level of L. acidophilus La-5 had a significant impact (p<0.05) on its survivability during the simulated digestion of ice cream samples, irrespective of the difference in viscosity. The log survival of L. acidophilus La-5 was on an average 3.64 log cfu/g and 4.08 log cfu/g for ice cream samples supplemented with higher and lower amount of L. acidophilus La-5, respectively at the end of 2 hr. Nevertheless, this difference in overall survival was not statistically significant (p>0.05).
These studies demonstrated the efficacy of low fat non-fermented ice cream in maintaining high viable numbers of L. acidophilus La-5 throughout its tested shelf life of 90 days. In addition, protective effect of ice cream on the viability of L. acidophilus La-5 against harsh stomach conditions was observed, but this effect was not as a result of viscosity of ice cream. It was also found that an ice cream supplemented with 106cfu/g would result in a similar overall log reduction of L. acidophilus La-5 at the end of 2 hr simulated digestion compared to an ice cream supplemented with 108cfu/g.
The aggressive stomach conditions had a negative impact on the survivability of L. acidophilus La-5 during digestion of all the ice cream samples, but this detrimental effect can be reduced by incorporating L. acidophilus La-5 into an ice cream matrix which would increase the opportunity of bacteria to reach the small intestine and provide the desired health benefit.

Full textAbstract:
Europe is in the midst of its deepest crisis since the 1930s where unsustainable debt-to-GDP levels are among the most alarming issues. It is so critical that it is unsure if the Euro can be saved. The risk of moral hazard increases within EMU when governments are taking too much risk in their public debt policies due to the anticipation that ECB or other Member States would eventually bail them out. Moreover, the SGP imposes restrictions on government deficits and debts but have previously failed to enforce them. The weakness seen in the past is that no sanctions have been put in place once the limits have been breached and the SGP is therefore incredible. Previous research on common pool and debt spillovers in a monetary union point to an upward drift of public debt as countries join the EMU. Does this argument hold true? In order to find out, 25 OECD countries between the years of 1995 and 2010 are analyzed using System GMM Arellano-Bover/Blundell-Bond one-step estimator. The primary balance, the interest payments, and GDP growth are regressed respectively in order to see through what channel EMU displays its effect. One regression will cover the entire time period and another will only cover the years from 1995 to 2007 in order to isolate the effects of the current crisis. The results, based on the years over the entire time period (including the crisis) suggest that the effect of an EMU Membership goes via the Interest payments which it is connected to positively. By using the equation of debt dynamics, the fact that net debt interest payments are higher for a country within EMU indicates, all else equal, that they have on average higher levels of debt. Nevertheless, this realization might be a crisis phenomenon and the implication of this is not clear. However more importantly, the regressions based on the years of 1995 and 2007 (prior to the crisis) did not display any significant results. These results indicate that there is no significant relationship between a country’s membership in EMU and its level of debt prior to the crisis.

Abstract
Elderly people are going to be a growing number in Europe. Between one third are going to be 60 years or older at 2025. For Sweden the situation is going to be similar. A reduced muscle function could lead to complications for the individual to perform daily tasks and will lead to a higher rate for falling and getting bone fractures. The positive sides are that for men and women there are a possibility for maintaining physical function and strength even in older years. The purpose of this study was to investigate the possibility of gaining strength in M. Quadriceps femoris among five elderly people. The training schedule followed over 6 weeks of time with training sessions twice a week, training the Quadriceps muscle with one set of each training session. The result shows that for the three people that completed the study, all of them managed to gain strength. Further the study examines resistance training comparing single and multiple sets. Is there any difference in gaining strength between training programs with single set training versus multiple sets training?

Full textAbstract:
This research study's the use of biological sulfate reduction technologies for the treatment of Sasol Secunda's coal-mine drainage (CMD) using Fischer-Tropsch Reaction Water (FTRW) as a cost-efficient carbon source. The research aims to develop a prototype dynamic model that describes this co-treatment of FTRW and CMD in both a continuously stirred tank reactor (CSTR) biological sulfate reduction (BSR) system and a BSR gas-lift (BSR-GL) integrated system. The BSR-GL system recovers elemental sulfur (S0 ) from the H2S produced and stripped from the BSR unit. Furthermore, this study aims to use the prototype model for a quantitative comparison of the CSTR-BSR and BSR-GL systems. Two bench-scale 5-litre CSTR-BSR and a 20-litre BSR-GL system were operated, under varying feed COD concentrations and hydraulic retention times (HRTs), to generate datasets for use in verification and a rudimentary validation of the prototype model. The BSR-GL integrated system includes 1) a 1-litre H2S gas reactive absorption (ABS) unit utilising an aqueous ferric solution for the recovery of elemental sulfur (S0 ) from sulfide and 2) ferrous biological oxidation reactor to regenerate ferric from the ferrous for re-supply to the ABS unit. The datasets generated in the experimental study allowed for the identification, mathematical modelling and reaction verification of 32 components that interact as reactants and products in 23 reactions observed in the two BSR systems. The prototype model is presented in a mass and charge balanced Gujer matrix that includes, i) 5 SRB mediated processes, ii) 2 liquid-gas mass transfer processes, iii) 3 processes describing the ABS and Fe2+ bio-oxidation units, iv) 4 processes describing sulfide and elemental sulfur oxidation and v) the S0 and poly-sulfide aqueous equilibrium and vi) 9 processes describing death regeneration and BPO hydrolysis. This prototype model was implemented in the DHI WEST® software for initial stage simulation trials. The experimental datasets allowed for the first-stage estimation of the best-fit reaction rate equations and the calibration of the kinetic parameters related to the 23 reactions, using MATLAB® curve fitting toolbox. A pre-processor that describe the pH and equilibrium chemistry of the components of the artificially prepared FTRW+CMD feed mixture batches under varying total concentrations have also been developed in this research. This was done to generated influent file to the DHI WEST® simulations that incorporated the dynamics related to the FTRW+CMD feed mixtures. The sulfate utilisation rate (gSO4 -2 .l-1 .d-1 ) of the GL-BSR and CSTR-BSR systems were compared to determine which system had the best sulfate removal. The results were found to be as follows; a. On comparison it was found that the sulfate substrate utilisation rate for the CSTR_BSR system is 39.28% of that of the BSR-GL_N2 system, where both systems were fed at feed mixture of COD of 2500mgCOD/l, where the COD:SO4 2- was 0.7, b. For the same systems fed a feed mixture of COD at 5000mgCOD/l (COD:SO4 2- = 0.7), the sulfate substrate utilisation rate for the CSTR_BSR system was found to be 17.86% less than that of the BSR_GLN2 system. c. Finally, it was also found that the substrate utilisation rate for the CSTR_BSR system was 30.06% less than that of the BSR_GLN2 system at Se of 4gCOD/l, for both systems fed substrate at 5000mgCOD/l. Thus, it can be concluded that the sulfate substrate utilisation rate for the BSR-GL system is higher than that of the CSTR_BSR system, for systems fed COD feed mixtures at 2.5 or 5gCOD/l where both systems have the same effluent substrate concentrations. However, the difference in the comparative substrate utilisation rate is less at higher feed substrate concentrations. This is the influence of substrate inhibition on the active SRB biomass, which increases with higher effluent substrate concentrations. Finally, this research found that the use of gas-lift reactor technologies is superior to CSTR technologies in the treatment of coal-mine drainage utilising biological sulfate reduction (BSR). The CSTR-BSR system, fed sulfate between 1.6 to 14gSO4 2- /l, produced effluent with high dissolved H2S concentrations, on average 285mgS/l and maximum at >600mgS/l. Releasing this effluent to the environment would be hazardous to aquatic and human health and corrosive to infrastructure. As such, the effluent from the CSTR-BSR system requires further treatment to stabilise the water for any use. The BSR-GL technology allows for the conversion of the H2S produced during BSR reactions to form elemental sulfur, which is a resource recovered from this process, thus complying to the circular economy aim of this study.

Full textAbstract:
En damm används i huvudsak för att magasinera vatten i energiutvinningssyfte. Dammen rör sig fram och tillbaka i ett säsongsmönster mestadels beroende på skillnader i utomhustemperatur och vattentemperaturen i magasinet. Det nordiska klimatet innebär risk för isläggning i magasinet, för vilken lasten är relativt outforskad. Denna rapport syftar till ett med multipla linjära regressionsmodeller samt dynamiska regressionsmodeller avgöra vilka variabler som förklarar en specifik svensk dammkonstruktions rörelse. Dammens rörelse mäts genom att mäta dammens förflyttning kontra berggrunden med data från dammens inverterade pendlar. Av särskilt intresse är att avgöra islastens påverkan på rörelsen. Resultaten visar att multipla linjära regressions-modeller inte fullständigt lyckas modellera dammens rörelse, då de har problem med autokorrelerade residualer. Detta hanteras med hjälp av autoregressiva regressionsmodeller där de initiala förklarande variablerna inkluderas, kallat dynamisk regression. Denna rapports resultat visar att de autoregressiva parametrarna fungerar mycket väl för att förklara pendlarna, men att även tid, temperatur, det hydrostatiska trycket samt istjocklek är användbara förklarande variabler. Istjockleken visar signifikant påverkan på 5 % signifikansnivå på två av de undersökta pendlarna, vilket är ett noterbart resultat. Författarna menar att rapportens resultat indikerar att det finns anledning att fortsätta forska kring islastens påverkan på dammkonstruktioner.A dam is a structure mainly used for storing water and generating electricity. The structure of a dam moves in a season-based pattern, mainly because of the difference in temperature between the air on outside of the dam and the water on the inside. Due to the Nordic climate, occurrences of icing on the water in the basin is fairly frequent. The effects of ice on the structural load of the dam are relatively unexplored and are the subject to this bachelor’s thesis. The goal of this project is to evaluate which predictors are significant to the movement of the dam with multiple linear regression models and dynamic regressions. The movement is measured by inverted pendulums that register the dam’s movement compared to the foundation. It is of particular interest to determine if the ice load influences the movement of the dam. The multiple regression models used to explain the dam’s movement were all discarded due to autocorrelation in the residuals. This falsifies the models, since autocorrelation means that they don’t meet the needed assumptions. To counteract the autocorrelation, dynamic models with autoregressive terms were fitted. These models showed no problem with autocorrelation. The result from the dynamic models were successful and managed to significantly explain the movement of the dam. The autoregressive terms proved to be efficient explanatory variables. The dynamic regression models also show that the time, temperature, hydrostatic pressure and ice thickness variables are also useful explanatory variables. The ice thickness shows a significant effect at the 5 % significance level on two of the investigated pendulums. The report's results indicate that there is reason to continue research on the ice load impact on dam constructions.

Full textAbstract:
Due to the increase in electrical demand and renewable penetration, electrical utilities need to improve and optimize the grid infrastructure. Fundamental components in this grid infrastructure are transformers, which are designed conservatively on the base of a static rated power. However, load and weather change continuously and hence, transformers are not used in the most efficient way. For this reason a new technology has been developed: Dynamic transformer rating (DTR). By applying DTR, it is possible to load transformers above the nameplate rating without affecting their life time expectancy. This project goes one step further and uses DTR for the short term and long term wind farm planning. The optimal wind farm is designed by applying DTR to the power transformer of the farm. The optimization is carried out using a Mixed-Integer Linear Programming (MILP) model. In respect of the transformer thermal analysis, the linearized top oil model of IEEE Clause 7 is selected. The model is executed for 4 different types of power transformers: 63 MVA, 100 MVA, 200 MVA and 400 MVA. As result, it is obtained that the net present value for the investment and the capacity of the wind farm increase linearly with respect to the size of the transformer. Then, a sensitivity analysis is carried out by modifying the wind speed, the electricity price, the lifetime of the transformer and the selected weather data. From this sensitivity analysis, it is possible to conclude that wind resources and electricity price are key parameters for the feasibility of the wind farm.På grund av ökningen av efterfrågan av elektricitet och förnybara energin, elförsörgingsföretag måste förbättras och elnätets infrastruktur måste optimeras. Grundläggande komponenter i elnätet är transformatorer, som är designade konservativt efter en statisk märkeffekt. Laster och vädret ändras dock kontinuerligt, detta betyder att transformatorer inte används på de mest effektiva sätten. Av denna anledning har en ny teknik utvecklats: Dynamisk lastbarhet hos transformatorer (DTR). Genom att applicera DTR, gör det möjligt att belasta en transformator högre än märkdata utan att påverka den förväntade livslängden. Detta projekt går ett steg längre och använder DTR för kort och lång sikts vindkraftparkplaneringar. Den optimala vindkraftparken är designad genom att använda DLT på krafttransformatorn för vindkraftsparken. Optimeringen utförst med hjälp av Mixed-Integer Linear programming (MILP) modell. Gällande transformatorns termiska analys, så valdes den linjäriserade toppoljemodellen av IEEE Clause 7. Modellen var utförd för fyra olika krafttransformatorer: 63 MVA, 100 MVA, 200 MVA och 400 MVA. Resultatet blev att nettonuvärdet för investeringen och kapaciteten av vindkraftsparken ökade linjärt med avseende på storleken på transformatorn. En känslighetsanalys var utförd genom att ändra vindhastigheten, elpriset, livstiden av transformatorn och de valda väderdata. Från känslighetsanalysen så var det möjligt att dra slutsatsen att vindresurser och elpriset är nyckelparametrar för vindkraftsparkens genomförbarhet.

Full textAbstract:
För att hantera den förändrade situationen i närområdet måste Försvarsmakten öka sin operativa förmåga och med det, även sin rekrytering. För specialförbanden har utebliven värnplikt inneburit en reducerad rekryteringsbas samtidigt som Försvarsmakten, för att öka sin operativa förmåga, bl.a. skapat förband med specifika kompetenser, förmågor och uppgifter vilket i sin tur lett till en konkurrenssituation avseende bemanning. För specialförbanden har detta tillsammans med ett lågt utfall från uttagningstesterna inneburit en utmaning att tillgodose det operativa behovet av systemets viktigaste resurs, personalen. Denna kvalitativa studie som baseras på semistrukturerade intervjuer och en workshop syftar till att, utifrån operativ personal vid specialförbanden, fördjupa förståelsen för hur utfallet av uttagningstesterna skall kunna förbättras. Studiens identifierade drivkrafter, som ligger till grund för individer att söka till samt fullfölja de fysiskt och psykiskt krävande uttagningstesterna, analyseras därför gentemot motivationsteorier, organisatoriska perspektiv och psykologiska begrepp. Studien tyder på att även om drivkrafterna för att söka till respektive fullfölja testerna skiljer sig åt, så bidrar dessa tillsammans med stödjande funktioner till individens förmåga att härda ut, vilken är avgörande för att fullfölja uttagningstesterna. Utifrån resultatet kan specialförbandens attraktion utformas och riktas på ett tydligare sätt. Vidare kan befintliga urvalskriterier vidareutvecklas för att ur det totala antalet sökande, kunna kalla de individer med bäst förutsättningar att lyckas fullfölja och klara uttagningsprocessen.The Swedish Armed Forces needs to increase the recruitment rate and operational capability in order to handle the developing situation in the region. For the Special Forces, the lack of conscripts has meant a reduced recruitment at the same time as the rest of the Armed Forces, in order to increase operational capability, has created units with specific skills, abilities and tasks, which in turn have led to a competitive situation regarding the staff. This together with a high attrition rate from selection process has led to a challenge meeting the operational demand regarding the Special Forces most valuable asset, the personnel. This qualitative research, based on semi-structured interviews and a workshop with operational personnel at the Special Forces aims to increase the understanding of how the outcome of the selection process can be improved. The driving factors identified in this research, which form the basis for individuals to apply to the Special Forces and complete the physically and psychologically demanding selection tests, are hence analysed in relation to motivational theories, organizational perspectives and psychological terms. The study indicates that the drive for applying to and completing the selection differ, however, both of them combined with supportive functions contribute to the individual's ability to persevere and are crucial elements for completing the selection process. Based on the results attraction of the Special Forces can be designed and directed more accurately. Furthermore, existing selection criteria can be refined in order to, out of the total number of applicants, be able to select the individuals with the best chance to successfully complete the selection process.

Full textAbstract:
After a stroke, gait and balance are often affected and an orthosis is typically required to facilitate postural control. This study has been conducted to examine how the Range of Motion in an Ankle-Foot-Orthosis (AFO) impacts on stroke patients’ dynamic balance. It was hypothesized that better dynamic balance would be recorded when individuals were wearing a flexible AFO. The tests that was used in this study were the Timed Up and Go test (TUG), and the Center of Pressure (CoP)/Center of Mass (CoM) inclination angle, both in Anterior-Posterior (AP) and Medio-Lateral (ML) planes. The three patients participating in this study were all users, or had been users of AFO’s, and during the study they were asked to wear a customized AFO with the possibility to change the settings to open, flexible and rigid ankle joints. The order was randomized within each patient. No clear pattern was observed across all patients, either in the TUG test or CoP/CoM inclination angles. Further studies are required to explore the impact that AFO flexibility has on dynamic balance in individuals who have had a stroke.

Full textAbstract:
Tunable white-armaturer utgör idag en stor del av marknaden och förväntas öka ytterligare under de kommande åren. Då många leverantörer idag producerar och marknadsför sina egna lösningar för att skapa ett dynamiskt ljus kan det vara svårt att veta vilken standard dessa lösningar håller och hur väl den tekniska specifikationen stämmer överens med verkligheten. Syftet med denna studie har varit att undersöka om informationen mot beställare är tillräcklig samt om den redovisade data av Tunable White-armaturer är korrekt. Studien bygger på två delar. En experimentell undersökning genomfördes där fem tunable white-armaturers CRI (färgåtergivning) mättes mellan olika CCT-nivåer (färgtemperatur) och sedan jämfördes det med vad leverantörer har specificerat på deras hemsidor. En enkätundersökning genomfördes sedan som riktades mot 144 ljusdesigners i Sverige, varav 52 valde att besvara enkäten. Frågorna berörde redovisning av Tunable white-armaturer samt vikten av en god ljuskvalitet med inriktning på CRI. Resultaten från författarnas experimentella undersökning visar att alla tunable white-armaturer som testades skiftar i CRI under olika färgtemperaturintervaller. Den största skillnaden som mättes var på fabrikat 3 där det skiftade 9 CRI mellan 2700K-6000K. En jämförelse kunde sedan göras och visade att två av fem leverantörers specifikationer inte stämmer överens med vad som redovisats i respektive produktdatablad. Av att tyda svaren från enkätundersökningen kunde slutsatsen dras att det finns mycket skilda åsikter angående de tekniska specifikationerna gällande tunable white-armaturer. En del ansåg att det redovisas tillräckligt väl idag medan andra ansåg att det inte redovisas tillräckligt väl. Majoriteten ansåg att det är mycket viktigt med en god CRI när man föreskriver tunable white-armaturer i sina projekt. Man kunde också se att många ljusdesigners önskade att man redovisade färgåtergivning i TM-30-15 istället för CRI-metoden eller att man bör redovisa i givna färgtemperaturer. Det som kan fastställas av denna studie är att det finns en tendens till att vissa armaturleverantörer har sämre CRI än vad företaget i fråga redovisat. Denna studie enbart mätt TW-armaturer från fem företag verksamma i Sverige samt endast vid 100% ljusflöde. Författarna anser dock att denna studie kan leda till en diskussion om bättre redovisning av tunable white-armaturer behövs, samt ge läsaren en ökad förståelse för komplexiteten inom området.Tunable white luminaires today form a large part of the market and are expected to increase further in the upcoming years. As many manufacturers today produce and market their own solutions to create a dynamic light, it can be hard to know what quality these solutions have and how well the technical specification is. The purpose of this study were to investigate whether the information to the user is sufficient and whether the presented data of tunable white luminaires is correct. This study is based on two parts. An experimental study where five tunable white luminaires CRI (color rendering) were measured between different CCT levels (color temperature) and then compared these to what providers have specified on their websites. The second part was a survey was conducted to 144 lighting designers based in Sweden, 52 of whom chose to answer the questionnaire. The questions concerned the presented information of tunable white luminaires as well as the importance of a good light quality focusing on CRI. The results from the authors experimental survey showed that all tunable white luminaires that where tested are changing in CRI under different color temperature intervals. The biggest difference that was measured was on manufacturer 3 where 9 CRI shifted between 2700K-6000K. A comparison could be made and showed that two of five of the suppliers specifications did not match with the authors measurements. By analyzing the answers from the survey, some conclusions could be drawn. There were very different opinions regarding the technical specifications of tunable white luminaires. Some felt that it is enough as it is today, while others felt that more information was needed. The majority considered it very important to have a good CRI when selecting tunable white luminaires in their projects. One could also see that many lighting designers wanted to present color reproduction in TM-30-15 instead of the CRI method or to present CRI at given color temperatures. What can be determined by this study is that there is a tendency for some luminaire suppliers to have worse CRI than presented. This study only measured tunable white fixtures from five companies operating in Sweden and only at 100% luminosity. However, the authors consider that this study could lead to a discussion about better specifications for tunable white luminaires, as well as giving the reader an increased understanding of the complexity of the subject.

Full textAbstract:
At an average age of 42 years, 10% of the nation’s over 607,000 bridges are posted for load restrictions, with an additional 15% considered structurally deficient or functionally obsolete. While there are major concerns with decks in 75% of structurally deficient bridges, often weight and geometry of the deck further limit the load rating and functionality of the bridge. Traditional deck systems and construction methods usually lead to prolonged periods of traffic delays, limiting options for transportation agencies to replace or widen a bridge, especially in urban areas.
The purpose of this study was to develop a new generation of ultra-lightweight super shallow solid deck systems to replace open grid steel decks on movable bridges and as well serve as a viable alternative in bridge deck replacements across the country. The study has led to a lightweight low-profile asymmetric waffle deck made with advanced materials. The asymmetry comes from the arrangement of primary and secondary ribs, respectively perpendicular and parallel to the direction of traffic. The waffle deck is made with ultrahigh performance concrete (UHPC) reinforced with either high-strength steel (HSS) or carbon fiber reinforced polymer (CFRP) reinforcement. With this combination, the deck weight was limited to below 21 psf and its overall depth to only 4 inch, while still meeting the strength and ductility demands for 4 ft. typical stringer spacing. It was further envisioned that the ultra-high strength of UHPC is best matched with the high strength of HSS or CFRP reinforcement for an efficient system and the ductile behavior of UHPC can help mask the linear elastic response of CFRP reinforcement and result in an overall ductile system. The issues of consideration from the design and constructability perspectives have included strength and stiffness, bond and development length for the reinforcement, punching shear and panel action. A series of experiments were conducted to help address these issues. Additionally full-size panels were made for testing under heavy vehicle simulator (HVS) at the accelerated pavement testing (APT) facility in Gainesville. Detailed finite element analyses were also carried out to help guide the design of this new generation of bridge decks. The research has confirmed the superior performance of the new deck system and its feasibility.

Full textAbstract:
Swarm robotics is the study of developing and controlling large groups of robots. Collectives of robots possess advantages over single robots such as being robust to mission failures due to single-robot errors. Experimental research in swarm robotics is currently limited by swarm robotic technology. Current swarm robotic systems are either small groups of sophisticated robots or large groups of simple robots due to manufacturing overhead, functionality-cost dependencies, and their need to avoid collisions, amongst others. It is therefore useful to develop a swarm robotic system that is easy to manufacture, that utilises its sensors beyond standard usage, and that allows for physical interactions. In this work, I introduce a new type of low-friction locomotion and show its first implementation in the HoverBot system. The HoverBot system consists of an air-levitation and magnet table, and a HoverBot agent. HoverBots are levitating circuit boards which are equipped with an array of planar coils and a Hall-effect sensor. HoverBot uses its coils to pull itself towards magnetic anchors that are embedded into a levitation table. These robots consist of a Printed Circuit Board (PCB), surface mount components, and a battery. HoverBots are easily manufacturable, robots can be ordered populated; the assembly consists of plugging in a battery to a robot. I demonstrate how HoverBot's low-cost hardware can be used beyond its standard functionality. HoverBot's magnetic field readouts from its Hall-effect sensor can be associated with successful movement, robot rotation and collision measurands. I build a time series classifier based on these magnetic field readouts, I modify and apply signal processing techniques to enable the online classification of the time-variant magnetic field measurements on HoverBot's low-cost microcontroller. This method allows HoverBot to detect rotations, successful movements, and collisions by utilising readouts from its single Hall-effect sensor. I discuss how this classification method could be applied to other sensors and demonstrate how HoverBots can utilise their classifier to create an occupancy grid map. HoverBots use their multi-functional sensing capabilities to determine whether they moved successfully or collided with a static object to map their environment. HoverBots execute an "explore-and-return-to-nest" strategy to deal with their sensor and locomotion noise. Each robot is assigned to a nest (landmark); robots leave their nests, move n steps, return and share their observations. Over time, a group of four HoverBots collectively builds a probabilistic belief over its environment. In summary, I build manufacturable swarm robots that detect collisions through a time series classifier and map their environment by colliding with their surroundings. My work on swarm robotic technology pushes swarm robotics research towards studies on collision-dependent behaviours, a research niche that has been barely studied. Collision events occur more often in dense areas and/or large groups, circumstances that swarm robots experience. Large groups of robots with collision-dependent behaviours could become a research tool to help invent and test novel distributed algorithms, to understand the dependencies between local to global (emergent) behaviours and more generally the science of complex systems. Such studies could become tremendously useful for the execution of large-scale swarm applications such as the search and rescue of survivors after a natural disaster.

Full textAbstract:
Bakgrund: Marknadens ökade dynamik resulterar i att allt fler företag genomgår digitala transformationer för att kunna utnyttja de teknologiska möjligheter som uppstår. Samtidigt resulterar en digital transformation i att företaget möts av förändrade kompetenskrav där digitala kompetenser blir allt viktigare för företags långsiktiga överlevnad. Denna dynamiska marknad har visat sig speciellt tydligt hos detaljhandelsbranschen och behoven av digitala kompetenser har ökat kraftigt. Men hur utvecklar ett detaljhandelsföretag dessa digitala kompetenser? Syfte: Syftet med studien är att bidra med en ökad förståelse för hur ett detaljhandelsföretag arbetar med digital kompetensutveckling hos sina medarbetare. Genomförande: Denna studie har sin vetenskapliga utgångspunk i det hermeneutiska perspektivet med en kvalitativ forskningsmetod. Empiriinsamlingen har genomförts genom semistrukturerade intervjuer med sex respondenter från ett fallföretag. Respondenterna har både varit från chef- och medarbetarnivå. Slutsats: Trots utmaningar i att identifiera vad för digitala kompetenser som saknades utifrån ett subjektivt synsätt så var det förmågan att ha ett flexibelt och utvecklande förhållningssätt och digital kunskap som bristen på digital kompetens bestod av. Dessa utvecklades genom tre tillvägagångssätt. Cheferna anställde dels nya medarbetare som skulle hjälpa de gamla att utvecklas. De anställda som fick vara kvar i företaget utbildades, både formellt och informellt varav den informella utbildningen var mest effektiv och använd. Cheferna tog även in konsulter och partners för att sprida vidare den digitala kunskapen till medarbetarna. Utöver detta visar sig företagskulturen och medarbetarnas inställning till förändrings viktig för hur effektiv den digitala kompetensutvecklingen blev.Background: Dynamic markets result in more and more companies having to digital transform their business in able to use the technological benefits that occur. At the same time a digital transformation will result in demand for new competencies where digital competencies is the most important for the companies long term survival. This rapidly changing market has been particular present in the retail industry and the demand for new digital competencies has been growing. But how does a retail company develop these digital competencies? Purpose: The purpose of this study is to create an understanding of how a retail company work with the development of digital competence with their employees. Completion: This study has a qualitative methodology with a hermeneutic perspective and an interative approach. The empirical material has been collected through semi-structured interviews with six respondents from one retail company. The respondents have been both from the management level and the employee level. Conclusion: Despite challenges in identifying what digital competence were lacking from a subjective point of view, it was the ability to have a flexible and evolving approach and digital knowledge that the lack of digital competence consisted of. These were developed through three approaches. The managers hired new employees to help the existing ones develop. The employees who were allowed to remain in the company were trained, both formally and informally, of which the informal training was most effective and most used. The managers also brought in consultants and partners to pass on the digital knowledge to the employees. In addition, the corporate culture and employees' attitude to change proved to be important for how effective the digital competence development became.

En sökning på ledarskapsutveckling via Google och databasen APA PsycInfo renderar sammanlagt drygt 200 000 träffar. Detta tyder på ett stort intresse för ledarskapsutveckling. Syftet med uppsatsen är att studera hur deltagare tar sig an uppgiften att bearbeta samt eventuellt vidareutveckla upplevelser samt förändringar som tar plats under och efter en UGL kurs. Frågeställningarna berör ämnen runt hur de i sin ledarroll arbetat med inhämtade kunskaper och hur de som individer upplever att de har påverkats. Vi intervjuade sex ledare från mellersta och södra Sverige som deltagit på en UGL kurs under 2019. Vi använde oss av en semistrukturerad intervju där valet föll på att bearbeta insamlad empiri med hjälp av en tematisk analys. Det som framkom när det gällde ledarrollen var utveckling av tydlighet, trygghet samt effekter av det egna ledarskapet och behovet av användbara verktyg. Det mest utmärkande på det individuella planet var att deltagarna upplevde att de fick kunskaper om sig själv. Grupputvecklingens betydelse var ett ämne som de flesta frekvent återkom till under intervjuerna. Trots det ringa, men ändå väl geografiskt spridda respondentdeltagandet, har vi fått ett relativt fylligt resultat. Detta gav insyn i deras upplevelser av hur kursen har påverkat dem, kunskaper de förvärvat som ledare och inverkan det haft på dem som individer.When searching for leadership development at Google and the database APA PsycInfo you get a about 200,000 hits. This indicates interest for the subject. The purpose of this essay is to study how the participants handle the processing and possible further develop experiences and changes that takes place during and after a course in UGL. The issues concern topics about how they, in their role as a leader, have worked with obtained knowledge. The issues concern topics about how they, in their role as a leader, have worked with acquired knowledge and the effect on them as an individual. We interviewed six leaders from central and south part of Sweden who, during 2019, has participated in a UGL course. We used semistructured interviews and choose to process the collected data using a thematic analysis. The most important thing that emerged about the role of the leader were the development of clarity, security and the effects of the individual leadership and the need for useful tools. The most characteristic on an individual level was gaining good knowledge about yourself. Group development was the topic that most frequently were mentioned during the interviews. Despite the small but well geographically dispersed participation of respondents, we provide insight into their experiences of how they got affected by the course, knowledge they acquired as leaders and the influence it had on them as individuals.

Full textAbstract:
Negli ultimi anni abbiamo assistito ad un notevole aumento del traffico dati mobile, trend confermato anche per il futuro, generato in gran parte da dispositivi smart e perlopiù legato alla metodica di accesso e scambio dati nota con il nome di video streaming. Si stima infatti che circa l'80% della bandwidth mobile mondiale nel 2021 sarà utilizzata per lo scambio di dati audio/video. Risulta dunque di fondamentale importanza per i provider di rete e dei servizi di video streaming, soprattutto quelli forniti on-demand, cercare di comprendere quali sono i parametri che maggiormente influenzano la cosiddetta QoE - Quality of Experience sperimentata dagli utenti finali, in modo da garantire loro il miglior servizio possibile (QoS - Quality of Service), mantenendo comunque alti i profitti.
Nell'ambito delle applicazioni e servizi di video streaming, in particolare, la qualità percepita dagli utenti finali risulta fortemente influenzata da diversi effetti di degradazione che possono verificarsi a causa di cattive condizioni di rete, soprattutto nello specifico ambito della mobilità.
Da questi studi risulta come, ad esempio, gli utenti preferiscono sperimentare effetti di degradazione temporale durante la riproduzione di contenui multimediali piuttosto che effetti di degradazione della qualità, risultati da cui derivano scelte implementative quali, ad esempio, l'utilizzo del protocollo TCP e la nascita del cosiddetto HTTP-based adaptive streaming, ovvero quella tecnica che permette di adattare la qualità dei segmenti scaricati in base al throughput, in modo da minimizzare il numero di interruzioni del servizio e massimizzare, al contempo, la qualità del media in download.
Dopo una rapida analisi delle principali tecnologie oggi utilizzate, si evince come vi sia la necessità di definire un unico formato per il manifest e per la struttura dei segmenti. Si arriva così alla definizione dello standard MPEG-DASH con le proprie euristiche di adattamento.

Full textAbstract:
Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode.Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.

Full textAbstract:
abstract: Video capture, storage, and distribution in wireless video sensor networks
(WVSNs) critically depends on the resources of the nodes forming the sensor
networks. In the era of big data, Internet of Things (IoT), and distributed
demand and solutions, there is a need for multi-dimensional data to be part of
the Sensor Network data that is easily accessible and consumable by humanity as
well as machinery. Images and video are expected to become as ubiquitous as is
the scalar data in traditional sensor networks. The inception of video-streaming
over the Internet, heralded a relentless research for effective ways of
distributing video in a scalable and cost effective way. There has been novel
implementation attempts across several network layers. Due to the inherent
complications of backward compatibility and need for standardization across
network layers, there has been a refocused attention to address most of the
video distribution over the application layer. As a result, a few video
streaming solutions over the Hypertext Transfer Protocol (HTTP) have been
proposed. Most notable are Apple’s HTTP Live Streaming (HLS) and the Motion
Picture Experts Groups Dynamic Adaptive Streaming over HTTP (MPEG-DASH). These
frameworks, do not address the typical and future WVSN use cases. A highly
flexible Wireless Video Sensor Network Platform and compatible DASH (WVSNP-DASH)
are introduced. The platform's goal is to usher video as a data element that
can be integrated into traditional and non-Internet networks. A low cost,
scalable node is built from the ground up to be fully compatible with the
Internet of Things Machine to Machine (M2M) concept, as well as the ability to
be easily re-targeted to new applications in a short time. Flexi-WVSNP design
includes a multi-radio node, a middle-ware for sensor operation and
communication, a cross platform client facing data retriever/player framework,
scalable security as well as a cohesive but decoupled hardware and software
design.Dissertation/Thesis
