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.

Solcellsdrivning av distribuerade inbyggda system

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

Givarkonstruktion för beräkning av sådjup

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.

LIN baserad kommunikationsmodul för GPS

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks.

The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.

En agil arbetsmetod för utveckling av ett leverantörsstöd

This thesis was made possible by the company Verendus system AB, which is the leading developer of dealership management systems in the caravan and camper market. The goal of the thesis was to create a statistics module for a new producer system envisioned by Verendus. The new system is aimed at manufacturers and importers of caravans and campers, with the goal of enabling its users to create more effective production lines. By providing statistical data to mentioned users they will be able to predict market trends and customize their production lines accordingly. Today such software does not exist which leads Verendus to think that its arrival would lead to a success on the market.Before the development and design of the producer system began, a new agile method had to be developed, MAM (Minimum Agile Method).

Evaluation of Xilinx System Generator

This Master?s Thesis is an evaluation of the software Xilinx System Generator (XSG) and blockset for Matlab. XSG is a module to simulink developed by Xilinx in order to generate VHDL code directly from functions implemented in Matlab. The evaluation was made at Saab Avionics AB in Järfälla, north of Stockholm. In order to investigate the performance of this new module XSG to simulink, a model of a frequency estimator often used in digital radar receivers were implemented in Matlab using XSG.

Att sälja grönt är skönt - En studie om att öka försäljningen av ekologiska varor

The interest for organic food has grown a lot over the last 15 years. Even so, only 3.5 % ofthe share of wallet in Sweden goes to organic food. The purpose of this study is to examine and describe how retailers can get consumers to buy more organic fruits and vegetables. The study was carried out by visiting six Coop Konsum-stores, of which three performed poorly and three performed well in organic sales. We conducted interviews with the department managers, customer surveys and in-store observations.

What happens during breakdown and repair of the suspensory ligament and what are different treatments aimed at?

Injuries to the suspensory ligament represent a huge problem in equine veterinary medicine. As many of the affected horses are elite-competition athletes, there are high expectations on veterinarians to make these horses fully functional again. The suspensory ligament has several features which makes the healing process complicated. So far no treatment has shown to optimize the healing process. This has led to the testing of many new treatment methods, in order to find a consensus for the injury.

Efterfrågan på beroendeframkallande varor : En studie om hur efterfrågan på snusprodukter har reagerat på prisökningar i Sverige mellan 1999-2009

Denna uppsats behandlar de relativa prisökningar som skett för snusprodukter i Sverige och vill undersöka om dessa har lett till minskad efterfrågan som nationalekonomisk teori föreslår. Utifrån teori och tidigare forskning har en efterfrågemodell konstruerats för att möjliggöra en statistik undersökning.Variablerna som ingår i modellen är inhämtade från Statistiska centralbyråns prisenhet och Swedish Match AB och inkluderar prisuppgifter för varor, försäljningsstatistik och disponibel inkomst under tidsperioden 1999-2009.Resultaten från regressionsanalyser för tidsseriedata visar på att de ökade priserna har haft en negativ inverkan på efterfrågan på snus under den gällande tidsperioden, men att denna effekt varit förhållandevis liten..

Car Lock Improved by Configurable Key

When a car owner want to lock or unlock his or her car today, it?s preferable done by using aremote control. The system is really comfortable when the car owner is using the remote.A problem arises if a thief gets the remote.The thief doesn?t have to know where the car is parked, an approximate estimation where thecar is parked is enough.For instance, it?s enough to know which car park the car is parked in. If the thief knows that,he/she can repeatedly activate the remote control while looking for a car indicating with lightsand sounds.Because of the fact that a car usually indicates that it has been unlocked by making a shortsound indication, there will be no problem finding the car.The purpose with this project is to make a prototype which makes it harder for a thief to findthe car.

Stabilisering av betongstommar : Beräkning av en ekvivalent beräkningsmodul med hänsyn till samverkande kort- och långtidslast

Vid stabilisering av betongstommar är det komplicerat att välja en korrekt elasticitetsmodul. Detta då stommens laster verkar under både kort och lång tid. I detta examensarbete utförs en noggrann kryptalsberäkning för varje plans vertikala element, där hänsyn tas till den varierande byggtiden. Utifrån det analyseras kort- och långtidslaster med respektive elasticitetsmodul för att erhålla en ekvivalent elasticitetsmodul som tar hänsyn till de olika belastningstiderna. Denna elasticitetsmodul bestäms efter förhållandet mellan stommens knäcksäkerhet, snedställning och den vindlast som verkar på byggnaden.Den ekvivalenta elasticitetsmodulen ligger till grund för mer noggrann indata än tidigare vid stabilitetsberäkningar och redovisas i diagram som sedan kan användas i det praktiska ingenjörsarbetet.Där inget annat anges utförs beräkningar enligt Eurokod 2.Där inget annat anges är figurerna ritade av författarna..
