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.

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.

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

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.

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.

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.

The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning social system and good resources to manage the problems and take advantage of the opportunities that the tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes conservation of the environment and improves the welfare of local people is what defines ecotourism. A concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back, without risking creating imbalances in society. Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.

Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.

Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.

De flesta metoder, verktyg och arbetssätt som används vid traditionell projektledning har använts under en lång tid trots att de yttre förutsätt-ningarna har förändrats. Systemutvecklingsbranschen upplevde de traditionella metoderna att driva projekt som oerhört statiska och tröga, därför utvecklades mer lättrörliga metoder som kom att kallas agila systemutvecklingsmetoder. Fram till år 2007 fanns inte en strukturerad process för hur valet och implementeringen av en agil systemutveckl-ingsmetod bör gå till. Det finns idag några ramverk som beskriver hur val och implementering av en agil metod kan bedrivas. Inget av dessa ramverk tar dock i beaktande eller utgår ifrån en organisations strategi eller vikten av strategisk passform.
