In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Syftet med studien var att beskriva hur ungdomar och vuxna med cerebral pares och en kommunikativ nedsättning upplever och resonerar kring vad som påverkar social delaktighet i vardagliga aktiviteter. För att besvara syftet valdes en kvalitativ ansats i form av innehållsanalys. Datainsamling genomfördes med skriftliga intervjuer via internet utifrån en intervjuguide samt genom tillgång till dagboksanteckningar. Analysen resulterade i ett tema "Samverkan av interna och externa faktorer påverkar upplevelsen av social delaktighet i vardagliga aktiviteter" samt två kategorier ?Personliga faktorer? och ?Omgivningsfaktorer?.

Ett balanserat aktivitetsmönster anses inom arbetsterapi vara en viktig komponent för att uppleva hälsa i aktivitet. Syftet med studien var att beskriva och förstå aktivitetsmönster och dess relation till upplevd tillfredsställelse med livet i allmänhet. Undersökningsgruppen rekryterades från en region i norra Sverige och bestod av 40 personer med diagnosen seropositiv reumatoid artrit. Datainsamlingen genomfördes med instrumenten Occupational Questionair, Life Satisfaction Questionnaire och FRIES index, bearbetades i dataprogram och redovisades med deskriptiv statistik. Resultatet visade att undersökningsgruppen hade en likartad fördelning av sina aktiviteter under dygnet.

Denna uppsats vetenskapliga grund hämtas främst från ekofeminism med tanken om jämställdhetsarbetets samband med miljövård, samt närvarons politik med teorier kring representationens betydelse för den politik som förs. Ekofeministisk teori menar att det finns betydelsefulla samband mellan förtrycket av kvinnor, icke-vita människor, och fattiga på ena sidan och den icke-mänskliga naturen på andra sidan. Detta innebär att kvinnor på ett bättre sätt förstår det förtryck som finns mot icke-mänsklig natur än män. Teorin om närvarons politik menar att det styrande idéfokuserade politiska systemet går miste om viktiga perspektiv och kunskaper som en mer representativ politik kan ge. Närvarons politik utgår från att politiskt underrepresenterade sociala grupper kan bidra med perspektiv och kunskaper som annars förblir ohörda.

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Verksamma i norra Sverige inom hemrehabilitering i primärvården eller slutenvård. Nio arbetsterapeuter i deltog i studien. Data samlades in genom semi-strukturerade intervjuer med stöd av en intervjuguide.

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.

Bakgrund: Sverige har som m?l att bli v?rldens b?sta land inom E-h?lsa 2025. Det finns begr?nsad forskning kring arbetsterapeuters erfarenheter att arbeta med digitala patientm?ten. Digitala patientm?ten kr?ver digital kompetens och att arbetsterapeuter kontinuerligt f?ljer utvecklingen. ?r 2020 fick prim?rv?rden drastiskt g? fr?n en traditionell och fysisk v?rd till en mer digital v?rd n?r pandemin br?t ut.

Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..

Solid State Drives (SSD) blir idag allt vanligare som lagringsmedium och håller på att bli ett alternativ till magnetiska hårddiskar. Denna studie+ har undersökt hur man på bästa sätt kan utnjytta SSDer i en MySQL-databas. Undersökningen genomfördes med hjälp av experiment där prestandamätningar gjordes för att få en klar bild på i vilken konfiguration av SSDs som ger bäst prestanda i MySQL. Mätverktygen som användes var sql-bench och mysqlslap.   Resultaten visar att en databas på en enskild SSD presterar lika bra som en databas med  SSD-cache  under  majoriteten  av  mätningarna  och  visar  bättre  resultat  än resterande konfigurationerna som var en databas på hårddisk och transaktionsloggen på en SSD. .

In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.

Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.
