AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Hematology-instruments that analyze blood cells can at specific cases be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

The aim of this paper was to investigate how 40 typical speakerswith Finnish accent, aged 65-84 years, performed in speech assessmentthrough Dysartribedömningen, a Swedish dysarthria assessment instrument.Their results were compared with results of a matched Swedish nativespeaking reference group. Both groups were assessed in areas offunction/structure, prosody/intelligibility and through a survey oncommunication. Results indicated that the performances of the Finnishparticipant group were estimated as more deviant than the Swedish,considering all areas. The Finnish participants were deviant in articulationand they had a significantly lower speech rate in reading. They also hadsignificantly lower scores in intelligibility compared to the reference group.The results of the survey of communication showed that the Finnishparticipants estimated their levels of activity and participation to besignificantly more limited compared to the reference group.

This report presents a thesis project conducted by two students at Mälardalens högskola. The project covers 15 points in industrial design and was conducted during April to June 2014. The principal of the thesis works at Plastic Produkter. The assignment was to develop equipment for an effective way to dose, mix silicon, fill a special designed plastic bag and then seal it. The bag is then formed into a breast model.When a customer for various reasons decides to do a breast augmentation or a breast reconstruction, there may be doubt or uncertainty about the result.

The purpose of this Master?s thesis is to investigate how academic librarians experience reference work aimed at international students. International students are a growing usergroup in Swedish academic libraries. The study?s main research question is:- How do academic librarians experience reference work aimed at international students?The study was performed with a phenomenographic methodological approach where seven qualitative interviews with academic librarians were conducted.

The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.

This report was written as a result of a Bachelor Degree Project at the School of Technology and Society at University of Skövde spring 2007, together with Jede AB in Mariestad. The report covers the development of a door to a coffee vending machine that is under construction, and will in a chronological order describe the project from ideas to final product.The project started with a rather extensive feasibility study that thru market research and user tests sorted out the opinions of potential customers, concerning today?s available assortment. Technical areas concerning materials and manufacturing methods were also scrutinized for the consideration of the possibilities of a future production.The next step was to constructively generate ideas and thoughts that later on could grow to be potential solutions. After several weeks of hard work and pieces of good advice and recommendations from the assigner, four comprehensive concepts were built up.

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.
