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.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

This is a master degree thesis at Royal Institute of Technology (KTH) betweenÅngpanneföreningen and Programma. KTH is the examiner, Programma is the client andÅngpanneföreningen is mentor for this project.Programma has a product called TM1800 that has problems with EMC; the problem is thatthis product does only pass the CE-check with a small safety margin. This problem can besolved by reducing the radiation from the electric components in the product or by reducing offix base frame. In this degree thesis the focus is only on mechanical redesign.The main problems right now depends on the long distance between the screws, there is anisolating layer on most of the parts and the forces between the joints are too small. The mainfocus is to solve these three problems.The best solutions are when the whole base frame is more or less redesigned instead of onlyredesigning some of the connection points.

This term project addresses how to develop construction drawings for a general contract.

The supervision is created as guide for similar projects.The construction drawings is a complete construction guide, hence it includes all construction drawings. In addition, a room description and a general description is included..

Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

When harvesteing ley there is always mechanical losses from the harvest machines. During the last years the roundbalers with knives,cutting the material-are more common, This use increase the mechanical losses of material. MATERIALS AND METHODS The roundbaler which used in this test was a Krone Vario Pack 1500 Multi Cut. This roundbaler has 17 knives. The theoretical length of cut was 64 mm. During the test we stretched a rubber tarp under the balechamber and collected the materials which fell down from the balechamber.

Aim: The aim of this study was to describe intensive care nurses? experiences communicating with patients during mechanical ventilation.Methods/design: A qualitative interview study. Interviews where analyzed using descriptive content analysisSetting: Nine intensive care nurses from two different intensive care units were interviewed using a semi structured interview guide.Background: Past research has shown that patients during mechanical ventilation in the intensive care unit, feel very vulnerable and the helplessness of being unable to speak. These patients feels that they are completely dependent on the nurses and their competence. It has been shown to be very important that the patient feels included, acknowledged and respected.Results: The analyzed data resulted in a theme; through communication strive to preserve patients´ dignity and three main categories; create relationship to the patient, minimize patients´ vulnerability and don´t give up.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

This paper investigates the grammatical construction intransitive motionconstruction with GOAL as it is used in Swedish (Swe. intransitivrörelsekonstruktion med MÅL).I examine in which ways the construction is productive, i.e. thepossibility to use the construction with new verbs as well as withordinary motion verbs with new functions. The notion of productivity isbased on the construction?s type frequency and semantic openness(Goldberg 1995, 2006; Barðdal 2008; Bybee 2010).

?Studies have shown that patients receiving mechanical ventilation in an intensive care unit (ICU), who are entirely dependent on the nursing staff, often experience frustration due to a temporary loss of the voice source. Limited communication is an important factor contributing to patient discomfort. Nursing staff also report communication as frustrating and difficult.The aim of the present study is to introduce a neck-type electrolarynx as a communication aid in an ICU, to study the nursing staff experiences of communication with tracheotomized patients receiving mechanical ventilation, and to examine the patient´s experiences regarding communicative abilities. Communication between a ventilator treated, tracheotomized patient and members of the nursing staff was recorded and analyzed according to principles of Conversation Analysis (CA).The results show that several members of the nursing staff experience difficulties communicating with tracheotomized patients receiving mechanical ventilation.

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

The shooting sport is one of the most widespread sports in the world and it isbeing practice in most countries. Based on their own experiences, in competition -and hobby shooting, the client M4Solutions found a demand and need for ashooting target that is manufactured in Sweden.The purpose of the project has been to develop, with the help of Marcus Walldén,two shooting targets from idea to finished product. These two shooting targets,Plate Rack Target and Dueling Tree, would each be equipped with a mechanicalresetting system but will in the future have the ability to be provided with anelectronic resetting system.The project from the client was divided into two theses. One of these two, writtenby Marcus Walldén, focused on the tripod parts and the overall design work forboth Plate Rack Target and Dueling Tree. The thesis that is presented in thisreport have focused on resetting systems, the design of protective plates and otherperipherals for both shooting targets.This work has primarily been in CAD environment where design, constructionand development has been given free rein.
