In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the Software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Denna rapport är skapad som syfte till att redovisa det erhållna resultatet av examensarbete vid Affärssystemprogrammet vid Kungliga Tekniska Högskolan (KTH). Arbetet har utförts som uppdrag för det serbiska företaget Soprex som är en underleverantör till ett svenskt företag. Rapporten är uppbyggd efter IMRAD metoden (Introduktion, Metod, Resultat och Diskussion).Uppdraget var att skapa en kravspecifikation för en modul som är en del av applikationen för hantering av olika kontrakt och prisberäkningar för Soprexs kunds olika kunder. Detta arbete fokuserad på kontrakt modulen. Arbetet har varit uppdelat i tre olika steg, syftet med detta har varit att successivt slussas in i företagets sätt att arbeta och lära känna deras standarder.

Antalet företag som köper färdiga standardsystem istället för att utveckla ett eget har ökat de senaste åren. Det största problemet med standardsystem är att det inte är anpassat speci-fikt för kundens verksamhet vilket innebär att viss anpassning av både system och verk-samhet är nödvändig.Syftet med denna uppsats är att undersöka hur två systempaketsimplementatörer ser på verksamhetsutveckling. För att uppfylla vårt syfte, ämnar vi att besvara följande fyra frågor.Anser systempaketsimplementatörerna att det är företaget som ska anpassa sig till deras sy-stem eller ska systemet anpassas till företagets verksamhet? Ska ansvaret för att integrera systemet i verksamheten läggas på kunden eller implementatören eller ska det vara ett sam-spel? Anser de båda systempaketsimplementatörerna att det är bättre att få kunderna att jobba med mer standardiserade processer istället för att anpassa systemen? Hur bidrar de båda implementatörerna till kundens verksamhetsutvecklingsarbete?Eftersom vårt syfte går ut på att ta fram implementatörernas åsikter och attityder om verk-samhetsutveckling har vi valt att genomföra en kvalitativ undersökning baserad på intervju-er. Anledningen till att vi valde en kvalitativ metod är för att vi avser studera respondentens syn på sin egen roll i utvecklingsarbetet.

The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer Software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Vi vill med den här uppsatsen undersöka om brukskvaliteter kan vara ett stöd vid mjukvaruutveckling, med fokus på dess kommunikativa egenskaper och hur de kan bidra till skapandet av samförståelse. Empirin för studien är hämtat från UIQ Technology i Ronneby som utvecklar en plattform för ?smart phones? och har ett starkt fokus på användbarhet.I denna uppsats beskriver vi deras arbete som två nivåer. Först ut är Vision vilket representerar dem som tar in kundens krav och skapar, eller formulerar, en vision utefter dessa. Därefter förs denna formulering ner till Utförande som står för dem som skapar den faktiska produkten.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

Inom IT-branschen läggs det mycket resurser på att effektivisera arbetssätt, och att hitta det optimala sättet att styra och leda projekt är en ständig utmaning. Dagens IT-organisationer befinner sig även i en situation där marknaden ställer krav på minskade kostnader men samtidigt en högre nivå av support och service. Utifrån detta har det genererats en uppsjö olika arbetssätt och tillhörande verktyg som alla har som mål att strukturera eller effektivisera systemutvecklingsprocessen. Ett av dessa arbetssätt är Lean IT som hämtar sina grunder från det väl beprövade produktionssystemet Lean Manufacturing.Inom systemutvecklingsbranschen arbetas det ofta i projektform och att ha en bra projektledning är ofta en av faktorerna bakom ett lyckat projekt. För att en projektledare ska kunna leda projektet till framgång krävs det att denne har en bra uppfattning om arbetssättet inom organisationen och projektgruppen.

Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.

Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
