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.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

This project concentrates on musicians who work in a professional music studio.The task of this project was to design a new headphone system called Foldback system.The advantage of this system is that all involved in a music project could influence their ownlistening during the project. With a couple of adjustments should each and everyone get theirown individual listening from their headphone station.This report shows different methods, theories and results that came along in development ofFoldback system. The project has resulted in a finished product that will be in use atStudiomega..

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

This report aims to identify and categorize suitable audit users and furthermore establish with values these users experience. The aim of the report has been fulfilled by analyzing interviews carried out with several companies using audits as a part of their risk management process. In addition to this, theories concerning management have been studied..

Working with health-management has become something most organizations would describe as essential for being legitimate today. The aim of this thesis is to investigate how this subject is handled in an existing company and how this work is percieved by the employees in the organization. Due to the fact that limited research has been conducted on this issue, we see this thesis as a potential for increasing the understanding of how health management is articulated in practice. Our results show that health management in our studied organization is far reaching in comparison with most organizations, but has room for improvement according to the Integral Theory. The consequence of differences in perceptions between management and employees could result in that health management does not become an integral part of the company and its daily operations to the potential extent..

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

 SammanfattningKravhanteringsprocessen är en av de viktigaste faserna vid utvecklandet av ett IT-system. Kravhantering är alltså grundläggande för att utveckla ett stabilt system som uppfyller beställarens önskemål. Med en väl utförd kravhantering som grund får man ett system som är fritt från bristfälliga fel, utvecklandet av systemet går även till på ett effektivare sätt. Vid byggandet av ett system eftersträvar man alltid en framgångsrik mjukvara. Kravhantering ses som den viktigaste faktorn vid utvecklandet av ett IT-system.Föreliggande studie genomförs som en litteraturstudie där undersöks vilka brister som är vanligt förekommande under kravhanteringsprocessen.

The increasing public concern regarding the government?s priorities in spending public resources puts pressure on public organisations to address quality issues in their practice. In United Kingdom both BRTF (Better Regulation Task Force) (BIS, 2005b) and the Hampton report (BIS, 2005a) highlighted management and quality problems in public organisations in UK. These reports revealed obstacles within institutions? intent to offer recommendations and appropriate solutions for agencies working with legal enforcement and control.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

In 1983 Sweden passed a law stating that all limited liability companies are to be included into a mandatory auditing system. According to the EEC, courts fourth amendment, each country has the right to decide whether to exclude a mandatory auditing system for smaller companies. Audit reports in Sweden are considered to be very important for the bank crediting system. Should this be eliminated, it would be more difficult for banks to trust an audit. The significance of calculated audits is questioned in regards to the banks accrediting system.
