This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.

This rapport is result of a project. The purpose of which was to design a circuit that is used in a heat glove. The heat glove is the technical aid which provides heat inside a glove.It is specially suited for old people who have problems with cold hands because of decreased blood circulation.There already was an old circuit in the glove that gives a constant current which develops heat from battery to glove through a circuit. The temperature is between 32 and 34 degrees.The problem with the existing circuit was to regulate the temperature. There is only on/off switch and there is no way to adjust desirable value of the temperature.In order to solve the problem the old circuit was investigated.

In this paper we analyze a social network specifically designed for the elderly, people with Dementia and people with generally low computer experience. This is a relatively unexplored use for such software, and our goal is to find out whether the technique to be used is simple enough to use for the intended user group, and generally how the whole situation is experienced by the users. To achieve this we conducted an expert evaluation and interviewed a number of users at two separate occasions during their first weeks with Modernfamilies. We came to the conclusion that this software generally is simple enough to use for the intended target group. Some of the users we came in contact with experienced the software as a positive addition to their daily lives, while some could not see any reason for a further use.

The aim of this study is to analyze how intercommunication between offenders are presented with artefacts during the planning and implementation of a robbery in a cash depot in Stockholm. The methodological approach is based on empiricism from police investigation protocols, which leads this study to a case study. The ambition is to analyze the empirical material from a sociocultural perspective. The results shows that the offenders use artefacts to plan the crime with artefacts within an internal intercommunication between the offenders. After the planning artefacts such as a helicopter, explosive material, telephones, saws and ladders have been used in an intercommunication to implement the robbery which leads to an analysis that hierarchy depends on the role of the artefacts, only when technical artefacts are included in the term of hierarchy..

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

An airline company that operates with its fleet needs to ensure that maintenance of a following and certain standard will be implemented. In this project we have sorted and divided the various working procedures of Malmö Aviation into Work Packs. These procedures are mandatory and must therefore be implemented in order to keep the aircraft airworthy at any time. Our task was to optimize and sort these working procedures by zone, panels, access and down time. We have created a maintenance program which Malmö Aviation can use and we have sorted their working procedures in B and C- Checks.Maintenance procedures that did not fit into our Work Packs have been gathered and sent back to Malmö Aviation for further inspection.This project has required a lot of extra reading in manuals and we have had a great insight into the complexity of a technical organization such as Malmö Aviation..

The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).

Trust is a concept used throughout our daily lives. We give trust to friends, colleagues and strangers. We also give trust to the technical artifacts we use in our everyday lives. We must also rely on the services we use to work the way we expect them to. There is plenty of research on trust in e-commerce and online banking on website based platforms.

A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.

Working with a three-dimensional shape that adjusts light seemed exciting. Venetian blinds became a basis and source of inspiration in my project. What is a Venetian blind? I arrived at the de?nition ?a surface of angleble pieces for sun adjustment?. From that simpli?ed meaning I started making sketches of what an alternative model could look like.

The production of cut flowers has diminished in Sweden and the remaining growers produce mainly in greenhouses. This situation could be changed if hardy, garden perennials suitable for Swedish conditions were to be used as cut flowers. A grower with suitable equipment as plastic tunnels or houses would be able to provide florists with an attractive assortment of perennials for cutting, during an extended selling period compared with the natural flowering period for these cultivars. This assortment would be based upon imported perennials already used by florists, but would also contain new products. To investigate the demand for locally field grown perennials as cut flowers, an inquiry took place.

This thesis has been written with our society?s current energy-situation in mind.Although it only deals with one particular block of buildings, the solutions and suggestions presented herein are quite applicable on other objects of the same type.This thesis is intended to be used as a guideline for energy-preserving projects in general, with an eye to buildings erected during the Swedish ?million-programme? in the sixties and seventies.The paper starts with the acquiring of all necessary blueprints and technical specifications. It then moves on to a thorough description of the buildings in question, and their heating- and ventilation-systems.Followed by this the reader is guided through the successive stages of energy-perseverance measures that are available, and possible. Reasoning around the economic factors concerning all measures is also held.The paper ends with conclusion, and a discussion concerning the delicate issue of the higher return-temperatures possibly reaching the district-heating plant..

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
