Design och implementering av enhandsburen RFID-läsare
Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.
Studie av strandskyddsdispenser i Gävleborgs län : Jämförelse mellan länets kommuner
En studie av hur Gävleborgs läns kommuner tillämpar strandskyddsbestämmelserna vid dispensbeslut. Studien består av frågeenkäter, intervjuer samt en genomgång av dispensbeslut i tre utvalda län mellan 2002-2006. Resultatet visar på att det finns skillnader i såväl bedömningen av dispensansökningar som i dispensbeslutens formalia..
Utvärdering av datorprogram för användning vid dagvattenutredningar
The main object of this diploma work thesis is about how computer programs can bea tool to use for work on stormwater investigations. The advantage of using acomputer program compared with calculations made by hand is evaluated anddiscussed. The computer programs that have been used for studies and a sequence oftesting of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs MikeUrban.Focus on sustainable development now permeates the building industry. As a resultstormwater investigations have been conducted in an increasing extent the recentyears. Stormwater is water produced due to precipitation, such as rain and snowmelt.Stormwater investigations normally contain descriptions of existing land use, plannedland use and suggestions of measures and technical solutions for the future disposal ofstormwater.The initial part of the thesis consisted of literature studies on stormwater andstormwater investigations to understand the science.
Parallel Registration of Ships
In present there is no Swedish legislation regulating bareboat registration of Swedish ships. Despite this absence however shipowners with vessels already registered in the Swedish Vessel Register do not hesitate to take advantage of the positive aspects of bareboat registration and thereby allowing the registration of their ships in another State as well. The fact that there is a lack of legislation in this area has left a legal loophole resulting in Swedish ships being registered in a second State without any regulation providing options or protection for the different parties involved. With this as a background, the main objective of this thesis is to analyze parallel registration of ships, its consequences and the future of dual registration in Sweden. To fulfil this objective another aim is to impart a collected legal and economical presentation of the problems that may occur when a bareboat chartered vessel is registered in two different States simultaneously.
Tidsberoende kvantkemiska beräkningar av optisk absorption hos polymerer och molekyler med litet bandgap
The vertical electronic excitation energies for the narrow-bandgap polymers LBPF, EP37 and EP62 have been calculated using Density Functional Theory (DFT). Also the vertical excitation energies for the acceptor unit of LBPF have been calculated using the Hartree-Fock (HF), DFT and Coupled Cluster (CC) methods. The calculations cover the visible and infrared wave length region and two strong transitions are obtained, one corresponding to the pi to pi* transition and one corresponding to the pi to Acceptor transition. The excitation energies obtained from DFT are below the corresponding experimental results and attempts have therefore been made to perform bench-marking calculations using a hierarchy of CC methods..
Brandsäkerhet i ett småhus
This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.
Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?
Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.
Angelägna allmänna intressen : En begränsning av möjligheten att genomföra kommersiellexpropriation?
Commercial expropriation occurs when real property is compulsory acquired by a private operator. This phenomenon is relatively new and has been criticized not only because of the rules concerning compensation, but also from the point of view of permissibility.An intervention in the protection of property must fulfill the requirement of important public interest set out in RF 2 kap. 15 § in order for it to be allowed. There is no definition regarding what constitutes an important public interest, the only thing that exist is a non-exhaustive list in the preparatory work. This in turn has led to the creation of a broad discretion when it comes to determining what constitutes important public interests.
Nedbrytning av dammbyggnadsmaterial: litteraturstudie och
laborationstester
Syftet med detta examensarbete har varit att se vilka material som är lämpliga att använda vid dammbyggnad samt vilka nedbrytande faktorer som verkar på konstruktionen under dess livslängd. Arbetet förklarar även vilka tekniker, så som erosionsskydd, som används för att skydda dammkonstruktionen samt även de olika laster som dammen utsätts för. Kontinuerlig nedbrytning av dammen kan ge dammhaverier vilket i sin tur kan ge katastrofala konsekvenser. Det är därför viktigt att det material som väljs till dammbyggnad kan stå emot de nedbrytande processer som finns under en lång tidsperiod. På de äldre dammkonstruktionerna används vanligen erosionsskydd av dumpat oordnat material medan Vattenfall rekommenderar erosionsskydd av ordnade homogena block på de renoveringar och nybyggnationer som utförs.
Skenbar arbetsbrist
In claims for unfair dismissal due to alleged redundancy, the burden of proof should be shared to enable an employee to have the cause of redundancy tried. In such a case, the employee should present evidence of an invalid cause ? such as personal reasons ? and the employer should account for the redundancy. With reference to their conflicting interests, the law favours the employer if the redundancy can be accounted for even if the employee maintains his or her position. This would have been reasonable practice if the employer?s evidence was subject to the same scrutiny as that of the employee but, as long as redundancy is considered a valid cause in itself, this is not the case.Redundancy does not come from nowhere, but it occurs when employers carry out their management decisions.
Visstidsdirektivets implementering i svensk rätt : Har korrekt implementering skett?
The essays main intent is to examine whether there has been a proper implementation of the Council?s directive 1999/70/EG into Swedish law regarding the requirement for measures to prevent the abuse of successive fixed-term employment contracts. To achieve this purpose there is a need for an examination of current law. The essay also has some secondary purposes. One of these secondary purposes is the question of whether the implementation of the Council?s directive 1999/70/EG has lead to a reduction of the workers employment protection, which is closely connected to my main question and the violation case.
Sammanställning och utvärdering av små avloppsanläggningar utifrån tillförlitligheten hos angivna reningsgrader
The private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.
Säkerhets- och arbertsmiljöarbete på Arbetsförmedlingen : Naturlig utveckling och påtvingade förändringar
Arbetsförmedlingen is the Swedish national authority responsible for the work politics, and its main purpose is to create and build a solid and sustainable job market.Economic crises together with changes in the society and in the organization over the past few years mean that the unemployed individuals that come in contact with Arbetsförmedlingen are no longer a homogenous group. A lot of effort is put into helping those who may find it difficult to enter the work environment, such as youths (19 ? 26 years old), people who have been unemployed or on sick leave for a long period of time, people with disabilities or immigrants who are newly arrived in Sweden.A harder social and economic climate can lead to frustration among the unemployed which mean that security measures at the offices has had to become adjusted. Local offices now have a public area where they have meetings with their clients and a locked open plan office space to which the public have no access. Working within an open plan office environment can cause health problems, mostly due to the constant background noise that comes from people having conversations on the phone, or with each other.
Erosion vid dagvattendammar : litteratur- och fallstudie om erosionsskydd
Köpenhamns cykelvägnät har anor så långt som 100 år tillbaka i tiden och på 1980-talet genomförde stadens cyklister stora demonstrationer för att få politikers och planerares uppmärksamhet, som man ansåg hade förlorat fokus på cykeln i planeringen (Jensen, muntligen, 2011-05-02). I detta arbete presenteras siffror som visar att det idag är fler än en tredjedel av Köpenhamns invånare som cyklar till och från sitt dagliga arbete. Köpenhamns kommun vill öka det antalet och målet idag är att bli världens bästa cykelstad år 2015 (Köpenhamns kommun 2007). För snart tio år sedan upprättade man på Köpenhamns kommun ett dokument, Cycle Policy 2002-2012, innehållandes mål för att förbättra förhållanden för stadens cyklister till år 2012. Detta dokument har studerats närmre i denna uppsats.Som blivande landskapsarkitekt blir jag nyfiken på hur de gått till väga.
Personbilar i singelolyckor med dödlig utgång på Sveriges vägnät : Orsaker till olyckor och rekommendationer om hur dessa kan förebyggas
In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.
