The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.

This Bachelor thesis examines the possibility of replacing an outdated, analog video recording system to a digital counterpart. It is key that the video and audio signals remain synchronized, generator locked and time stamped. It is up to nine different video sources and a number of audio sources to be recorded and treated in such a manner which enables synchronized playback. The  different video sources do not always follow a universal standard, and differ from format as well as resolution. This thesis aims to compare a number of state of the art commercial of the shelf solutions with proprietary hardware.

The purpose of this study is to examine how employees in an organization using flexible work practices, experience that passive face time influences the evaluated of them. Further, the study aims to understand to what extent that perception of passive face time motivates the employees to spend more time at the office than is necessary for their work situations. The study concludes that employees in general perceive that passive face time does influence how they are evaluated and that this perception motivates employees that are relatively newly employed by the company to spend more time at office..

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.

Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

The purpose of this study is to analyse the discourse on political exclusion in the official report Demokratiutredningen. It has been my ambition to relate the analysis of the report to a critical academic discourse on political exclusion and thereby make visible hidden norms and structures which functions to exclude certain individuals and groups from political participation.My paper point out that the report establishes a strong link between democracy and participation and that it, therefore, makes a strong case for a process of democratic inclusion. Though, in my study I suggest that that there is an unawareness of the importance of norms, hegemonic conceptions and structures and that inclusion, therefore, is unlikely to take place. Furthermore, I criticize the focus on deliberative democracy in the report. With insights offered by Mouffe in her argumentation on the necessity to acknowledge the dimension of antagonism present in all societies I underline that the focus on this democratic model is problematic.My conclusion is that the analysis presented in the report is insufficient if we want to create a democratic system characterized by equality..

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

This thesis examines why working time preferences differ between workers and nations, and explains the effect of working time regulation and working time flexibility on negotiating work-life balance. In five separate sections the following working time issues are examined: the number of hours worked by workers in Europe; factors affecting individual working time preferences; how working time preferences are negotiated in the national industrial relations systems of Sweden, France and the United Kingdom; how the institutions of the European Union have influenced working time negotiations through the Working Time Directive; and the benefits and practices available to organisations implementing working time flexibility. Broadly this paper views working time preferences as being a highly personal and influenced by factors such as wages, taxation, culture (national and workplace) and non-work responsibilities. It is argued that negotiating a preferred working time pattern is essential to achieving work-life balance and when such a balance is achieved, workers are more healthy, motivated and committed to their employer. Essentially this provides an incentive for businesses to voluntarily implement working time flexibility beyond the regulatory standards..

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

This is a report on the development and implementation of the web shop ?Urballa Ur?, a web application developed by nine students at Linköping university. The report illustrates the methodology and process with intention to answer the question ?How can an online watch store be implemented to increase sales??. During the process the agile method scrum has been used as a working method.

A new FPGA suitable for space applications has just reached the market. To investigate whether there are any possible flaws or limitations similar to those previously seen on FPGAs, an evaluation has to be done. This master thesis contains the evaluation of this new radhard FPGA with focus on possible design limitations and package related electrical phenomena.Areas evaluated: Ground-/VDD bounce, Cross talk, Rise time sensitivit, Power cycling, Power consumption, Place and route tool, Radiation hardnessThis report contains all steps in the evaluation. From method to measurements, comparisons, theory, results and conclusions. In the evaluation work, special effort has been made to develop designs that really stress the FPGA to find potential problems.

This report is an analysis of the gender representation in Swedish sports media, a comparison between sport in public service television for adults and children. The study explores the differences between the number of male and female sports in the matter of air time and also the number of male and female appearances in the TV shows. The programs studied in this report are the Swedish SVT?s Sportspegeln and Lilla sportspegeln. When we began this analysis we were under the impression that men would be over-represented, but that representation in sports television for children would be more gender equal than the adult counterpart. The result of the analysis confirmed previous studies stating that men dominate the sports programs in Swedish public service television.
