This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything. The surveys were distributed to various local companies. After having received a lot of answers, I concluded that the clear priority was the most positive feature of scrum and the most negative was that it was difficult to get the rest of the organization to understand scrum, which creates problems. Both high school class and local companies believe in scrum?s future, even if they think scrum will be partially modified to adapt to the software-development in the future. According to the survey responses, the most important to get the projects to be successful both now and in the future is that everyone who work with scrum is right educated..

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

This bachelor thesis includes two different manuals and design of an interface box between a test object and a general test station (computer) with ARINC429 communication.There are three different purposes with this project:The first is to setup a general test station with ARINC429 communication using a communications card from DDC (DD-42916i3-300) and software from Ampol Technologies (dataSIMS).The second is to design a new interface between the test computer and the test object. As well as implementing two components in the equipment.The third is to write two separate manuals to guide the users of this equipment. There are two different kinds of users of this equipment, technicians and system engineers. Technicians use the equipment to test and repair flight components. System engineers will implement new components in the equipment.The result of this project is a working test station with a new interface and two manuals..

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Physical activity can reduce the risk of developing dementia, and studies show that people who already have some form of the disease can get a better memory function and find it easier to perform daily tasks if the activity is performed regularly. People who are diagnosed with dementia are generally not offered physical activity to a high extent, nor is there a wide range of equipment developed to suit the target group.The Bike Around project was launched during a workshop in Copenhagen and was organized by HCH and Techna Science with the aim to develop new training equipment for people with dementia. The workshop resulted in the development of a customized training bike where the user can get a biking experience from his wheelchair or favorite chair. By integrating the pedal movement with a prerecorded movie projected on a screen, the memory can be stimulated both visually and by the activity itself.Our assignment in the project consisted of three parts: design of the bike, movie playback and software programming. During the project a prototype has been created that meets the requirements of ergonomics and usability..

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences.

This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.

This report is the final part within our education, Industrial Organization and Economy focusing on Logistics and Management at Jönköping School of Engineering. The aim with this report is to coordinate recycle drives for deposited aluminum-cans and bottles collected from grocery stores within Jönköping county and locality.In the present situation both aluminum cans and bottles filled with drinks are distributed to the grocery stores by the brewery?s own distributers. At the same time as they supply the drinks they also discharge the grocery stores units with restored aluminumcans and bottles. To make it easier for the grocery stores to handle the goods in the future, all distribution of drinks ought to be directly delivered to the grocery stores own separate central warehouse.
