This thesis was conducted at AB Fredr Wagner in Ösmo in Nynäshamn, Sweden.AB Fredr Wagner provides solutions for the graphic industry and has been asked by acustomer to develop a product that can simplify handling of EUR-pallets, namely amechanical arrangement, further called pallet exchanger that can switch from anempty pallet to a fully loaded one using only hand force.The goal with the thesis was to create design documents for a pallet exchanger, andalso from those documents to manufacture a prototype for testing and evaluation.A field trip was made to the customer, IKAB mailing in Huddinge, where the palletexchanger is thought to be placed. The purpose of this field trip was to get an insightinto the current work condition and need of change, as well as to gather informationregarding the requirements when it comes to size and robustness of the palletexchanger. Existing equipment on the market that can perform similar tasks werestudied in order to find an optimal solution for the actual pallet exchanger.After the field trip and gathering of information the concept generating phase began.The method used for generating concepts was brainstorming. To decide on whichconcept to use, a concept selection matrix was created. The selection criteriaincluded in the matrix came from the requirements for the pallet exchanger.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

VD:n för spelindustrins intresseorganisation (Interactive Digital Software Association) förutspår i den årliga State of the Industry rapporten för åren 2000 ? 2001, att spelindustrin snart kan nå 70 procent av världens hushåll, vilket gör spelmaskinen, näst intill, lika vanlig som videon. I denna dag börjar många spelutbildningar växa fram i hela landet, så som i Karlshamn, Visby och Kramfors. Trots denna tillväxt finns det nästan ingen akademisk forskning i ämnet speldesign. Detta gör att hjulet i många fall tvingas återuppfinnas om och om igen.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

Abstract I have made a Website called ?Art school? for Liljevalchs art Gallery, Culture administration in Stockholm and Culture school in Stockholm. It is with scholarship from these that this Website has been possible. The work whit the ?Art school? started in the autumn of 2005 and ended in May 2006 on distance from Stockholm towards Blekinge technology school in Karlshamn. The Webb place is for the general public, but most for people who have interest in art and for those how want to learn more painting in different mediums. This Websites I name: oil, watercolour, acrylic, coal, gouache, and graphite. On each one of these mediums you?ll get to know about their history, what technique they have, what sort of material you need, practise and tip.

Introduktion: HIV-infektion medför en kronisk och progressiv sjukdom som, i obehandlad form, leder till en successiv försämring av immunförsvaret och utvecklandet av AIDS.Syfte: Att vid två lärosäten undersöka sjuksköterskestudenters kunskaper om HIV och inställningen till behovet av HIV-testning.Metod: En empirisk tvärsnittsstudie med deskriptiv och komparativ design med kvantitativ ansats. Genomförd som enkätstudie bland studenter vid Högskolan i Gävle och Uppsala Universitet (N=95), som studerade på sjuksköterskeprogrammets tredje år. Resultat: Majoriteten (88,4 %) angav korrekt att samlag med fler än en partner ökar risken att smittas med HIV. Tre studenter (3,2 %) angav felaktigt att det finns ett vaccin mot HIV-infektion. Nästan hälften (42,1 %) saknade kunskap om att glidmedel, tillsammans med kondom, inte minskar risken för HIV-smitta.

In a school for children from 6-9 years in a small town in the southeast of Sweden, is areading activity program in progress since 8 years. The original purpose of this program wasto enhance the student?s reading interest. All of the students read at least one book a week andthen they review the book in front of the class.The purpose of the present study was to examine vocabulary, word retrieving, narrative skillsand grammatical abilities in children in this school. The objectives were to investigate if thechosen language abilities in these children were different compared to normative data andearlier studies in children at comparable ages.

Public participation is a key aspect in the planning of Swedish municipalities. It is probably the most important tool of them all in the planning towards a sustainable future within the cities and the municipalities as a whole. Participation from the public can take on several different forms. In this paper I focus to research and discuss in and around the usage of a web-based 3D platform called City Planner. The tool allows the user (the public) to view the municipalities planning in a fairly new (but quickly growing) environment.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.

The report describes a measuring method for analysis of energy consumption measurement in microwave ovens. Concurrently that the awareness of the environment evolves the demands are growing for more power saving products. This is also counting within the Home Appliance business, which is Whirlpools business area. Whirlpool is therefore interested of launching microwave ovens with documented low power consumption. To be able to implement this, both asserted measuring equipment, that fulfils all demands, and a standard procedure is required.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

The focus of this work is to study whether public libraries should offer their patrons unlimited access to the Internet, or restrict which sites they can visit. The most common tool used to limit Internet access is filtering software. The author has administered four interviews with public librarians working in libraries in Southern Sweden. All four librarians had different opinions about restricting Internet access. The most important question asked was if they had chosen to use filtering, and the reasons for their decision.

Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.
