Abstract:
This thesis explores if there is a connection between municipal demographics and how often the municipality involves users with disability in the development of its online services. The thesis derives its theory from previous studies on user involvement and participation (UPI),  e-government development and county bureaucracy. The method is quantitative, with data gathering through surveys aimed at municipality representatives as well as downloaded from Statistiska Centralbyrån. The analysis consists of statistical methods and tests of analysis using the software SPSS. The result is analyzed b

Abstract:
Syftet med detta examensarbete var att beräkna vad det kostar att ha UPS-kraft (Uninterruptible Power Supply). Arbetet utfördes för Västfastigheter på Södra Älvsborgs Sjukhus (SÄS) i Borås. Studien utfördes på en UPS i drift i byggnad 7. UPS: en i denna byggnad har 10 kVA kapacitet och är av dubbelkonverterande typ. Batterier av Ni-Cd (Nickel-Kadmium) typ används till backup med UPS: en. UPS av dubbelkonverterande typ är känd för att skapa mycket övertoner, men är fördelaktig för dess skyddande förmåga mot spänningsspikar.Mätningar har gjorts för att beräkna kostnadsberäkningarna.

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2011.<br>ENGLISH ABSTRACT: The digital control of UPS systems has been difficult in the past due to a lack of DSP technology. It was for this reason not possible to establishing the necessary control to regulate the voltages and currents of the UPS systems. Recent advances in DSP technology have however provided the means of establishing central control of the UPS system as well as incorporating more complex closed-loop control algorithms by utilising a single floating-point DSP.

Abstract:
With the increased usage of electrical equipment for various applications, the demand for quality power apart from continuous power availability has increased and hence requires the development of appropriate power conditioning system. A major factor during development of these systems is the requirement that they remain environment-friendly. This cannot be realized using the conventional systems as they use batteries and/or engine generators. Among various viable technologies, fuel cells have emerged as one of the most promising sources for both portable and stationary applications. In this t

Abstract:
Asymmetric multi-cores (AMCs) are a successful architectural solution for both mobile devices and supercomputers. These architectures combine different types of processing cores designed at different performance and power optimization points, thus exposing a performance-power trade-off. By maintaining two types of cores, AMCs are able to provide high performance under the facility power budget. However, there are significant challenges when using AMCs such as scheduling and load balancing. This thesis initially explores the potential of AMCs when executing current HPC applications and searche

Abstract:
The memory system is a significant contributor for most of the current challenges in computer architecture: application performance bottlenecks and operational costs in large data-centers as HPC supercomputers. With the advent of emerging memory technologies, the exploration for novel designs on the memory hierarchy for HPC systems is an open invitation for computer architecture researchers to improve and optimize current designs and deployments. System simulation is the preferred approach to perform architectural explorations due to the low cost to prototype hardware systems, acceptable perfo

Abstract:
Solar Power and Uninterruptible Power Supply (UPS) are two technologies that are growing rapidly. The demand for solar energy is mainly driven by the trend towards cheaper solar cells, making it economically profitable for a larger range of applications. However, solar power has yet to reach grid parity in many geographical areas, which makes ways to reduce the cost of solar power systems important. This thesis investigates the possibility and potential economic synergies of combining solar power with UPS systems, which have been previously researched only from a purely technical point of view

Abstract:
The thesis deals with Uninterruptible Power Supply (UPS) and associated problems of backup power in case of unexpected outages of electricity. Start of work is dedicated to limitation of the electricity supplies, as well as their causes and consequences. Furthermore, brief history of UPS and subsequently distinguish between UPS’s architectures. There is also a description of the energy sources such as batteries, flywheels or fuel cells. Part of thesis describes security of electricity supply in health care facilities, including requirements for emergency power. The own design of UPS is describ
