In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

The company is currently in a stage of improvement and has therefore taken the help of students at School of Engineering, Jonkoping University. The current production is batch, production layout is fixed. A bottleneck is created after the first station which leads to large efficiency loss.  The meaning of this report was to provide a layout suggestion with balanced workstations to a new production line. The conditions were that the production line would be one-way, driven by customers order and meet a demand of 40 products per week.

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

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.

Syftet med arbetet var att göra ett koncept av en robotcell som kunden skulle presentera för den Europeiska koncernen. Med konceptet som grund skulle koncernen ta ett beslut om de ville investera i en robotcell för att kunna utöka sin produktflora. Ett krav för att tillverka robotcellen var att göra den så flexibel som möjligt eftersom kunden ville producera olika varianter av samma produkt. En simulering i robotstudio blev en grund för en film som visade hur materialet tillverkades i robotcellen och även vilka materialprocesser som ingick vid förädlingen av materialet.Varje koncept började med en ritning i sketch för få en enkel överblick av hur layouten kunde se ut. Därefter bestämdes det om layouten var realistisk och om det skulle bli någon 3D modell av layouten.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

This Master?s thesis is one of two parts of a combined project called Sustainable development around the Lake Victoria, the purpose of which is to investigate the importance of local anchoring and active participation in the work towards sustainable development. The present study aims to investigate whether men and women are empowered by the participatory rural appraisal (PRA) process promoted in their villages by the VI Agroforestry Project Masaka/Rakai. The study is primarily based on interviews with farmers within the project area and brings up a local perspective on the concepts sustainable development, active participation and empowerment. The study shows that to improve the farmers? livelihood and to create a sustainable development in the community, the farmers have to be actively involved in, and in control of, the process.

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

This is a report for our thesis that was conducted as a conclusion of our bachelor degree in Business engineering at the Royal Institute of Technology (KTH). The work is done in cooperation with the firm Navigate Consulting Business Solutions AB.They have their leading expertise in Oracle E-Business Suite and has previously chosen to implement Oracle EBS R12. The modules that are planned to be implemented are general ledger (GL), accounts payable (AP), accounts receivable (AR), project module (PA), purchases, and CRM. For a consulting company like Navigate, it is particularly important to have a simple and effective time reporting process. We were therefore asked to provide new tabs with a decision-making process to determine if Oracle Time & Labor (OTL) is a useful time tracking system for their business.In order to achieve the company´s aim and objective we decided to follow a development method with five different phases.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Vi har i denna rapport jämfört produktionsmetoder vid byggande av gång- och cykeltunnel under järnväg. de metoder vi har jämfört är lansering och platsgjutning. Projektet som vi har studerat är byggandet av en gong- och cykeltunnel under järnväg vid Mjölby station. Vid detta projekt lanseras halva tunneln in och halva platsgjuts. Det vi har jämfört är dels de geotekniska aspekterna, där vi främst har tittat på vikten av förundersökningar, jordegenskapens inverkan, spontning och grundvattnets inverkan.

This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.
