Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

This paper investigates the usability of the intelligence test Wechsler Nonverbal Scale of Ability (WNV). Twenty four children in two different age-groups were tested with WNV, 10 children between ages 5 - 6, and 14 children between ages 9 - 10. The WNV turned out to be a useful test when some verbal communication was used in the test situation. This was especially apparent among the younger children, who needed extra verbal instructions and verbal support through the different subtests. The test also contained standardized verbal instructions for all ages.

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.

Detta examensarbete behandlar barns motoriska förmåga på tre olika förskolor, utifrån ett MUGI-test. Vårt syfte var att undersöka om det går att utföra ett MUGI-test på femåriga barn. Vi har observerat barnen som utförde övningar i MUGI-testet. Vi har kommit fram till ett resultat, som vi sedan har diskuterat och analyserat. Resultatet visar att nästan alla övningar är för svåra för barnen att genomföra, därför blir vår slutsats att MUGI-testet inte går att genomföra med femåringar på grund av att de inte kommit så långt i sin motoriska utveckling..

I detta projekt jobbar vi för att skapa ett program åt Infozone Sverige AB tillsammans med professionella utvecklare från företaget. Programmet är en webbportal som används till att övervaka och visa driftinformation om ett nätverk. Tanken är att denna portal skall integreras i ett ännu ej byggt system för nätverksövervakning som Infozone senare kan sälja till kund. Produkten tas fram med Scrum samt testdriven utveckling och under utvecklingen jobbar laget med bestämda metoder och SOLID-principerna för att säkerställa programmets kvalitet. Webbportalen utnyttjar moderna teknologier och ramverk för webbutveckling, bland annat är den en Single Page Application (SPA), använder följsam webbdesign och utnyttjar Microsofts .NET-plattform.

AbstractThis study examines the technologies appropriate in developing back-and solutions for search-driven user interfaces of e-commerce sites. The study is based on existing research in search-driven user interfaces of e-commerce sites from a design point of view, but instead the focus of this study lies within a back-end perspective. This choice of focus is a result of the gap that was encountered within research and other literature when it comes to general advice in how e-commerce sites best should build back-end solutions to support search driven user interfaces. The technologies that have been examined and compared are traditional relational databse management systems (RDMS) and the newer so called No-SQL database management systems, and also traditional search engines and the newer variant s of search engines. The study concludes that in some cases it is appropriate to combine traditional and newer technologies when it comes to databases, while the comparison of search engines indicates that there are some newer search en gines that have the ability to meet more of the needs that can be identified on the back-end solutions.Primary data consists of interviews made ?face to face? with experts on the subject and questionnaires addressed to selected e-commerce companies via e-mail.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

A personality test is a useful tool in recruitment contexts. Studies have shown that participants distort their answers in a socially desirable manner. The purpose of this study was to investigate if people respond more or less socially desirable depending on how they rate themselves in a personality test, based on the "big five" personality dimensions.Eighty people, (40 women and 40 men), 19-42 years, (M= 24,1 SD= 3,76) rated themselves on a personality test. Group one, (20 women and 20 men) completed the test on paper. Group two, (20 women and 20 men) completed the test verbally.

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

Idrottare använder i många fall prestationshöjande tillskott för att öka sin explosivitet, uthållighet och få en bättre återhämtning. Vid prestation ställs olika fysiska krav för den som utövar en specifik idrott. Det kan exempelvis handla om krav på rörlighet, snabbhet eller uthållighet, för att utövaren ska lyckas med sin prestation. Tidigare studier om prestation har visat att kreatin och koffein är två ämnen med en faktiskt bevisad prestationshöjande effekt och är där av vanligt att använda som tillskott. Craze är närmare bestämt ett så kallat ?Pre workout? (PWO) tillskott som intas innan träning eller en match och påstås ge effekter som ökat fokus, ökad styrka, mer energi och snabbare återhämtning.

This is a study of the national test in 3rd grade. The national test is obligatory and is conducted in 5th and 9th grade, but since the spring of 2009 the tests also become mandatory in 3rd grade. The case study of this research is to find out how children in 3rd grade perceive the purpose of the national test. The survey should also clarify how students think and feel about the national test, and how they feel before the national test and after they have finished writing the test. Has the test positive or negative influence on children? The survey will also show how much teachers clarify what the significance of the national test is for the students.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
