Deterministisk Komprimering/Dekomprimering av Testvektorer med Hjälp av en Inbyggd Processor och Faxkodning

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

Resurssnåla materialflöden - En fallstudie på Volvo Powertrain

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

Mobilt community - Bygga själv eller hjälpa till? : Kommersialisering av en plattform för användardriven karttjänst i mobiltelefoner

Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.

Reagera och agera: Styrka och snabbhet i den manuella responsen för emotionella stimuli

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

Analys av haptoglobin i bovint serum med surface plasmon resonance biosensorteknik :

The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.

USA:s m?ngfacetterade strategi i Myanmar En komparativ analys av liberalism och realism i amerikansk utrikespolitik

This thesis examines the USA?s response to the military coup in Myanmar 2021 through a comparative analysis of the two dominant international relations theories: realism and liberalism. The study uses a qualitative text analysis of the US Burma act of 2021 to test the explanatory power of the theories in the formulation of US policy. The results shows that liberal theory has the greater explanatory power, as the US response was systematically motivated by a normative desire to restore democracy in Myanmar. However, some realist tendencies could be observed, especially through exception clauses preserving US national security interest and the mention of China?s support for the military junta in Myanmar.

Energisparläge i automationsindustrin : Potential för att minska tomgångsförluster med industriella styrsystem

Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving mode during idle times. The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.

Tillit, förtroende och misstro : En kritisk granskning av enkät- och frågeformulär som använts inom statsvetetskaplig forskning

In this paper I have conducted an analysis to critically examine survey questionnaire forms used in political research to measure trust and distrust. During the first step of the analysis I aimed to identify how the concepts where used in the forms. The second step involved examining if it was possible to relate the questions and items to five theoretical assumptions based on theories of trust (and distrust). The third step was to examine the quality of the forms, in relation to survey and questionnaire designs.The results of the analysis showed that the institutes that conduct the studies tended to use similar questions to measure trust. Some of the forms that where analyzed had very many questions, which could lead to exhaustion for those participating in studies.

Fjärrlåneverksamheten på Borås och Kalmar högskolebibliotek

The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..

Tillväxtreaktion hos skärmträd i högskärm av gran i Medelpad :

Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

Företagsmodell för byten av systemutvecklingsmetod : från vattenfallsmodellen till Agila metoder

As changes occur more frequently in IT- and software development, it is important for the companies to meet the demands and needs of its customer. The companies have to be able to adapt themselves continuously in order till fulfill its customers changing needs in an effective way, which results in big changes of the companies? structures. The more traditional way of working is often replaced with more alternative approaches as a response to the reputable deficiencies of its predecessors. As an effect of the rapid change and development some companies now see big potential in switching to more Agile and flexible methods and some companies have no choice but to change their way of working.

Stubbtransporter - en jämförelse av tre olika transportsystem

In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

Försvarsministerns försvar : En studie i kriskommunikation

A politician on the peak of his career suddenly sees himself in the middle of not one or two, but five different crisis, that demand a fitting response and a well planned crisis management strategy. While focusing on ethos and its development, the following paper analyses the communicative strategies used by Germany's ex-minister of defense, Karl-Theodor zu Guttenberg. Within his one and a half year tenure he had to handle continuing accusations against policy and character. Guttenberg, who in many eyes was seen as Germany's most popular politician and whose ethos, therefore, prior to the first crisis could be described as strong, is loosing his trustworthiness among the military and other politicians the longer each crisis continues.The purpose of this study is to identify the communicative pattern of Mr. Guttenberg, which in the end lead to his resignation, while his popularity continues to be strong.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

Dagligvarumarknaden : en samhälls- och distributionsekonomisk analys av internet som försäljningskanal

Structural changes on the grocery market usually take place when the consumer is persuaded to take on the more labourintense parts of the distributionprocess. Internettrade changes this by causing competition between the unpaid work done by consumers and the labor performed by employees. In this master thesis grocery shopping on the internet is analyzed in a economic perspective with focus on distribution, changing marketstructures, driving forces and the future potential of internet as a saleschannel. The main conclusions are that consumerdemand and the belief in electronic commerceas a costreducing mechanism as well as a powerful new marketing tool were the driving forces behind the fast growth of grocery shopping on the internet. Electronic commerce introduces a new model of distribution with changing roles for consumers and grocerychains.
