Statistics of occupational injuries show that bricklayers are among the most exposed, with heavy lifting by far the most common cause of long-term sick leave. Prefabricated brick beams create yet another risk of injuries that can be prevented by auxiliary equipment or alternative solutions. From articles, interviews with masons and from a survey carried out in conjunction with this report, it appears that there are frequently difficulties in the use of available means for lifting and handling. Previous studies on the subject of transverse reinforcement in masonry beams indicate a viable method for bridging large openings in masonry walls. This bachelor thesis delves into whether the idea could be realized in today's brick construction with a view to improving occupational health and safety.

The aim of this small thesis is to investigate if the probability of business failure is higher at the time of divestment than at the time of acquisition for portfolio companies that have been subject to private equity ownership. The background for this thesis is the widespread critique aimed at private equity firms, claiming that they increase the risk in their portfolio companies. We have performed a study of 53 buyout transactions, involving Swedish Manufacturing companies, covering a time span of 13 years, from 1995 to 2007. We find evidence of an increased risk of business failure for the portfolio companies with a short forecasting horizon (within one year). The absolute increase in the sample is however small.

The purpose of the present quantitative study was to examine gender differences inperceived job satisfaction in two departments, with different work patterns, in a SwedishManufacturing industry. The questionnaire contained 30 statements and five backgroundquestions. The questionnaire was designed in combination of Job Satisfaction Survey (JSS),Work demands, Social support, Control and Competence (ASK), Questionnaire forPsychological and Social factors at Work (QPS Nordic) and Minnesota SatisfactionQuestionnaire (MSQ). Job satisfaction was measured based on the categories influence atwork, leadership, employee influence, work requirements and the physical environment. Theresults of the present study showed an interaction of gender and department where the femaleindustrial workers, who worked with more monotonous and standardized work tasks, valuedall of the categories of job satisfaction the lowest, except for the category employee impact.The results are believed to depend on that the women in the department had greater demandsfor variety in the work..

The object for this study is a company developing and Manufacturing vehicles for heavy transportation. The company distributes their products on a global market. Therefore the company is required to have efficient internal production development processes in order to successfully beat the competition. The purpose of this master thesis is to study how this particular company intends to implement their standardized theoretical product development process within their organization and how well it is done. We intend to identify and specify if the process has any unexploited capacity.

This thesis focuses on RM and customer relationships and tries to answer two research questions: how firms can retain customers and how to generate profitable customer relationships by using relationship marketing. We conducted case studies on JOB media, a company in Luleå, and Polardörren, a company in Öjebyn, Piteå. Our research has revealed that in many ways our case study companies conform in major ways to the theory in this particular area. However there are differences between how these two firms go about in regard to customer retention and establishing profitable customer relationship. We have discovered that JOB media, which is a service company is more inclined to maintaining close and long-term relationships with its customers.

This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the Manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

Forecasting is an important part in attempting to predict how companies will perform in the future. The more accurate the prediction, the more valuable are the results obtained from the forecast. This thesis aims to investigate forecasts of return on equity, and whether a disaggregation of the leverage formula into its underlying components affects the forecasting ability positively. This is conducted by comparing a model based on the leverage formula's components with a model solely based on return on equity from previous years. The study includes Manufacturing companies on the Swedish Stock Exchange over the period 1998-2011.

This thesis report describes the development of concepts regarding how weight can be reduced to the analytical instrument Biacore 4000. This thesis has resulted in five different concept proposals, all of which is solutions to reduce the instrument's weight.The thesis started with a pre-study where the instrument's structure and function were studied using both Solid Works, the opportunity to study the instrument in real life were also possible done. During this phase, a weight study was conducted as well, in which the instrument's weight distribution was studied and mapped.Following the initial phase, the work proceeded by developing concrete concepts to reduce the weight of the instrument where focus mainly was on the two cabinets. In addition, another two concepts were revealed, both with a more general approach.At the final phase of the thesis, the concepts were compiled and evaluated among themselves and the initial instrument.The thesis resulted in a study of the instrument's structure and weight distribution, with suggestions on how weight may be reduced for the instrument.The result factors such as materials, and Manufacturing were aspects that were taken into consideration.At the final section of the report, suggestions for further work in which different aspects are discussed can be found..

The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of Manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .

Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of Manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the Manufacturing of the conductor. It is then used when the resistance is to be decided for coarser aluminium conductors. A conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.

This thesis is the result of the author?s interest in music and electronics, namely the design and Manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
