Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

Growing up as a child, we had a Dog. To us, it was like a means to an end. That is, hunting other animals for food and for protection, with no special care and treatment given to this animal. Butas days passed by I began to witness a wind of change against such actions. I was made to understand that we were committing two crimes-: using the Dog as a means to an end (for hunting and for eating animals).

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The project was based on a request to improve an already existing program and hardware at the electrical engineering department at the royal institute of technology. For maximum ease of use, tests have been done on students to properly design the program for what it is meant to be used for. These tests have been transcribed and analysed, then brought back to the group in a discussion and then transcribed and analysed again, I call this process the ?four step process? (this process is presented and explained in chapter 6.4.). A part of this master thesis was also to analyse the four step process to enhance validity of this research.The project resulted in a new program with a new graphical view and features to help students and researchers to work with the technical tool for electromagnetic readings of planar objects.

SammanfattningExamensarbetet är utfört vid Fujita laboratory på Tokyo Institute of Technology.Detta examensarbete beskriver teori och bakgrund av en visuell observatör somhar forskats på vid Fujita laboratory.Att använda visuella sensorer, det vill säga kameror, kan bland annat hjälparobotar att agera autonomt i okända och i dynamiska miljöer. Syftet med envisuell observatör är att estimera ett objekts position i förhållande till robotensamt hur objektet och roboten rör sig gentemot varandra, med hjälp av bildensom fås från kameran.Syftet med examensarbetet har varit att studera teorin bakom observatören ochhur den anpassas till två olika kameror, en hålkamera och en panoramakamera.Fokus har legat på att utvärdera observatörerna experimentellt samt jämföra deolika kamerorna. Observatören för de båda kamerorna modelleras och simulerassedan och testas slutligen experimentellt. Examensarbetet innefattar även denbildbehandling som behövs för att göra experimenten möjliga att genomföra.I slutet av examensarbetet jämförs observatörerna för de olika kamerorna medavseende på korrekthet i estimering, robusthet mot parameterosäkerheter samtkänslighet för störningar.Resultaten visar att observatören för panoramakameran är känsligare förstörningar än den för hålkameran. Resultaten visar också att observatören förhålkameran är känsligare för parameterosäkerheter.

This study investigated relationships between high level language functions and phonological working memory in adults by correlating results oftests in a test battery used for investigating subtle language disorders and digit span task results. Results of two digit span tasks were analyzed in relation to demographic factors. 103 subjects without neurological disease, 20 ? 79 years old, participated. Significant correlations were found between the digit span tasks and most of the tests.

ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.

In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

Tests with users showed that there was an interest in a mobile application and it was a highly appreciated project. The web application ease diabetes nurses in their work with their diabetes patients in the way that the web application can display graphs of the patient's blood glucose level. .

The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..

In this paper we take a look at digital applications to help the user with public transportation. The main goal was to evaluate the problem a user can face when aiming to use the public transportation system, and to create a application for Apple Iphone that can enhance and help the user, no matter if he is familiar with the local public transportation system, or if he is less familiar with it. The aim was that the user wouldnt need any previous knowledge to be able to use our application. We combined Location-Based Services with Realtime-travelinformation and trip planning to examine if this combination could make both of the two different user-groups satisfied. To understand the problematics a user faces when approaching the public transportation-scene, Scenario-Based Design is evaluated as a method to grasp this problem.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

Small scale internal consumer tests provide a company with a cheap way to get valuable information regarding their products advantages and flaws. Therefore the demand for possibilities to do this kind of test has increased. This report is part of a new sensory project at Unilever. It presents a method for sensory comparison of the company?s own products with the corresponding competitor products.
