The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.
Fönsterglas : vilka, var och varför?
På dagens fönsterglasmarknad har produkter med samma funktioner och utseende fått olika namn. Detta är förvirrande och gör det svårt för en person som ska beställa fönsterglas att jämföra olika tillverkares produkter med varandra. Rapporten är tänkt som en översikt på de olika fönsterglasen som finns på marknaden idag och även på sådant som kan bli aktuellt i framtiden. Den berör också sådant som kan vara av värde att veta vid användning av fönsterglas. Målgruppen är alla som kan tänkas ha intresse i ämnet - alltifrån hobbybyggaren till fackmän i byggbranschen.
Affekter för hållbarhet
Syftet med denna studie var att undersöka vilka samband det finns mellan
värderingar, föreställningar och normer kring miljön till agerande för
ekologisk hållbarhet i det vardagliga livet. Vår hypotes var att det finns
samband mellan affekter kring miljöns framtid och agerande till hållbar
utveckling. För att söka svar på syftet och bekräfta hypotesen har enkäter med
frågor gällande individens värderingar, föreställningar och normer om miljön
samt frågor om miljömässigt agerande skickats ut via e-post till 119 deltagare
i åldern 23-65 år. Svarsfrekvensen var på 59 procent. Resultatet visade att det
fanns ett flertal starka samband mellan miljömässiga värderingar,
föreställningar och normer till individens agerande och hypotesen om att det
fanns samband mellan affekter och agerande för hållbar utveckling verifierades.

An investigation into the needs of such a system is conducted and a prototype printed circuit board assembly is manufactured.The prototype is developed with focus on protection against electrostatic discharges and overvoltage. Among the functions that are included are voltage measurements, communication interfaces and control of input and output currents. Firmware for the prototype is developed and configured to communicate with a PC through USB interface for control and collecting of measurements..
Protection of Regional Values - A comparative study of EU and ASEAN
Regionalisation has become an increasingly important phenomenon in a globalized world. As models of regional integration, the European Union (EU) and the Association of Southeast Asian Nations (ASEAN) are two prominent examples. This thesis seeks to explore through a comparative analysis, the different mechanisms and institutions for handling breaches against fundamental values within the two regional organizations. Inter-linked with the issue of the legal-institutional framework is that of what values the mechanisms are designed to protect. The method used for the analysis is first and foremost that of public international and European law, but the thesis also attempts to give a broader picture of the issues presented.
Säkerheten i trådlösa nätverk
The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.
Industrilandskapet i Norrköping : Kunskaper, värden och väg till bevarande

Validering av Casmo-5M / Simulate-3
The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).
Uppvärmd konstgräsplan : Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar
For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.

På rätt sida om gränsen? : Om EU:s yttre gränskontroll, folkrättens räckvidd och skyddsbehövandes rätt till rättigheter
Idag befinner sig över 50 miljoner människor på flykt runt om i världen. De har behövt lämna sina hem till följd av väpnade konflikter, förföljelse eller andra grova människorättskränkningar. Flera av dem behöver få skydd i andra länder. Dock är det svårt för många att få det. Inte minst gäller det de skyddsbehövande som försöker finna en fristad inom EU.
Vem är ett barn? En kritisk idéanalys av Barnkonventionen
Nearly half of the worlds population is individuals under the age of eighteen. The UN Convention on the Rights of the Child state in its first article that a child is ?every human being below the age of 18 years?. Our aim and purpose with this essay is to problemize this broad definition. Our hypothesis is that the definition brought by the UN Convention on the Rights of the Child is too wide and therefore brings difficulties when children of different ages beneath eighteen should and shall be treated the same.
Fastighetsbildning inom strandskyddat område : En studie av tillämpningen i två kommuner
Stränder och strandnära områden utgör i många avseenden en värdefull miljö som i Sverige skyddas tack vare vår strandskyddslagstiftning. Strandskyddslagstiftningen är en naturvårdsföreskrift som syftar till att trygga allmänhetens tillgång till stränder och bevara goda livsvillkor för växt- och djurlivet. Skyddet är generellt, dvs gäller alla stränder i Sverige och innebär bl a ett förbud mot uppförande av ny bebyggelse. Fastighetsbildning inom strandskyddat område utgör en åtgärd där hänsyn måste tas till strandskyddsbestämmelserna. Åtgärden kräver en bedömning där förrättningslantmätaren, efter vederbörligt samråd med kommunen eller länsstyrelsen, avgör om strandskyddets syfte motverkas eller inte.
Solceller som energikälla och solskydd för tält
This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.
Demokrati - skyddar det mot fred? : ? en teoriprövande fallstudie på konflikten mellan Ryssland och Georgien 2008
The aim of the following paper has been to test the democratic peace theory through applying it on the conflict between Russia and Georgia in 2008. This to either falsify the theory or come to the conclusion that the states? democracy was not satisfactory in regards to the definition of liberal democracy. The questions asked are: Was Russia and Georgia democratic states? Is democracy a protection from war? And which aspects of the liberal democratic theory, if any, were not satisfactory in either of the countries? The results show that the democratic peace theory is valid in this case and that neither one of the states were democratic.
