This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a Locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly Locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

Within the political science research it is common to examine the effects on the national parliaments caused by European integration. In this Bachelor Thesis the aim is instead to show what involvement of the national parliaments in the European Union implicates to the European integration process.The object of examination is the introduction of the parliaments as supervisors of draft legislative acts, this is also known as ?the Early Warning Mechanism?, through the ratification of the Lisbon Treaty. An analysis of answers from the national parliaments in the tests of three pilot cases, conducted by the COSAC, is made with help of Institutional theory and an Europeanization perspective.The main findings show that the mechanism of early warning probably will not become an obstacle for continued European integration, but it could slow down the process in some areas. Most probably though is that the mechanism forces the national parliaments to adapt and to be better equipped to react at events taking place at the European level.

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

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.

I denna rapport redogör projektgruppen för resultatet i kursen examensarbete 15hp (C-nivå) utfört på maskiningenjörsprogrammet, inriktning produktutveckling och design, vid Jönköpings Tekniska Högskola.Examensarbetet har utförts i samarbete med Kongsberg Power Product Systems AB i Ljungsarp. Syftet var att utveckla en ny typ av övre teleskopfunktion till Kongsbergs modulsystem för ställbara rattstänger.Utgångspunkten i projektet var att skapa en mer ergonomisk förarmiljö, något som Kongsbergs kunder och marknaden för långsamtgående fordon allt mer efterfrågar. Kraven som ställts på projektet bestod i största del av axiella och radiella krafter som konstruktionen skulle klara av, samt den axiella förlängningen av rattstången.För att strukturera arbetet har en produktutvecklingsmetod från boken The Mechanical Design Process av David G. Ullman använts. Dessa metoder har använts i genomförandefasen för att leda fram till resultatet.Projektet har resulterat i ett koncept som löser Kongsbergs krav på förbättrad förarergonomi..

When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..

This diploma work has been based on finding a solution to Hälsoteknikcentrum i Halland. The task was to design the wheels of a wheelchair gear, so they can put on and remove with a locking feature.I have sketched out the solution and drawn up in Catia v5, which will be handed over to health technology centers for accounting.  .

This thesis investigates the Designated Operational Entities (DOEs) under the Clean Development Mechanism (CDM) of the Kyoto Protocol. The DOEs serves as independent third-party auditors with the task of validating, verifying and certifying projects under the CDM. The majority of the DOEs are private entities. This is in line with the CDM objective of including the private sector in the climate change combat. The introduction of private entities in the role of DOEs can be questioned from a legitimacy point of view, but is corresponding to a development in international environmental governance where private actors are increasingly involved in governance arrangements.The thesis concludes the DOEs to be a form of public-private partnership and investigates the legitimacy of this form.
