This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

The construction business is one of the most accident prone businesses in Sweden. In order to make it safer it?s vital that all employees of a company report all accidents and incidents that occur. This report intends through qualitative interviews, to analyze the knowledge and attitude towards incident reporting among the employees of the Swedish construction contractor JM.The goal of the thesis work is to hopefully contribute to an increase of employees? awareness on those issues.

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations.

This project investigates how team sports can be used to include young women in public space aswell as how through the addition of a sporting facility adjacent to three schools can be used as a stepping stone for the young people of Dharavi to have a chance at a brighter future..

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.

The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.

How do we match our education with the needs of the construction line of business and the requirementsof the Swedish National Agency for education? Is there something that we have to change?In this study I have asked our former students about their opinion of our education and I have also asked them to give me their view on what a good teacher is like. I have been able to benefit a lot from their answers in my efforts to be that good teacher. This survey took place at Facebook.The answers showed that we carry on a piece of solid workmanship. But you can always improve, try harder.

Syftet med detta arbete är att undersöka hur förändring av material påverkar varseblivningen av objekt när formen lämnas oförändrad. Detta kan vara av intresse då spel med realistisk grafisk stil blir mer och mer högupplöst vilket samtidigt ställer högre krav på de grafiska utvecklarna att framställa verklighetstrogna material.Jag har utfört en kvalitativ undersökning med personintervjuer av sex personer. Dessa sex personer har fått se tre objekt där de fått definiera objektets syfte. Intervjupersonerna fick sedan se objekten med olika material där mina frågor haft som mål att få respondenten att motivera uppfattat material samt det uppfattade materialets egenskaper. De intervjuades motiveringar om objekt och material har jag sedan tolkat utifrån litteratur om psykologi, främst om kategorisering som George Lakoffs bok "Women, Fire, and Dangerous Things" (1990) beskriver.Min undersökning har visat att uppfattningen av textur kan förändra ett objekts syfte och funktion.

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

Denna rapport ger en bild av vilka olika saker byggherrar i Sverigeanvänder sig av idag för att öka den sociala hållbarheten. De projektsom studerats är Bygga om Dialogen i Malmö, Älvstaden i Göteborg,Vivalla i Örebro och föreningen Byggemenskap.Genom att intervjua en person från varje område studeras likheteroch skillnader i hur man arbetat med den sociala hållbarheten vidbyggnation. I Malmö och Örebro studeras arbetet med att öka densociala hållbarheten vid renoveringsobjekt, hur får de hela områdensom länge haft ett dåligt rykte att bli socialt hållbara där stort fokusligger på att anställa långtidsarbetslösa.I Göteborg och i föreningen Byggemenskap fokuserar man på attföra in den sociala hållbarheten vid nybyggnation och hur vi kan byggahyresrätter som har en lägre hyra än nybyggda lägenheter i dagslägethar..

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..
