Marknadsundersökning: Lämpliga flygplan med avseende på start- och landningssträckor för Bunge flygfält

In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.

Halvledare för höga strömmar i fordon

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

Barnperspektiv : En kvalitativ studie om hur handläggare i två kommuner beaktar barnperspektivet inom ekonomiskt bistånd

The purpose of this study was to examine social workers working process in social assistance with focus on the child´s perspective. We were interested in learning about the existence of variations in approach and attitude between two municipalities. Question to be answered about what methods and approaches used by social workers to include the child´s perspective in the process of social assistance. Another question to be answered about what the manner in which social workers took into account the child´s perspective when the families apply for social assistance in relation to the operations and requirement. To fulfill the purpose, qualitative methods were used.

Generisk Kravspecifikation

Denna rapport innehåller information från ett examensprojekt för två studenter från Jönköping Tekniska Högskola förlagt på företaget Fläkt Woods AB i Jönköping. Syftet med projektet har varit att framta en generisk kravspecifikation innehållande kravsättning och verifieringsmetoder samt redovisning av vilka krav som har testats.Metoden som använts är kvalitativa intervjuer av anställda verksamma inom utveckling av nya produkter. All denna information och input har bearbetats till en generisk kravspecifikation i ett Excel-format under förkortningen PRV (Product Requirement and Verification matrix). Projektet har haft stort fokus på att återkommande krav ska beskrivas i en form som ska kunna anpassas till så många av företagets produkter som möjligt. Detta har lett till att majoriteten av dessa återkommande krav har visats sig vara icke-funktionella och krav relaterat till lagar och direktiv.

Klimatsimulering av ett kontorsrum : Hur de termiska stigkrafterna påverkar ventilationseffektiviteten

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

Utveckling av nytt koncept för positioneringsslid

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

En studie av idrottslärarrollen i skolor med Waldorfpedagogik

AimThe aim has been to describe the goals and the pedagogic model concerning physical education in the Waldorfschool. Further purpose was to describe what the teachers focus on in there teaching roll about physical education. We have also chosen to give a picture of what other documents says about the teaching roll in booth the Waldorfschool and in the traditional municipal pedagogics. The Waldorfschool runs under Lpo 94 but they can also as other schools adapt and formulate there own curriculum after there pedagogic. That?s also why we have chosen to look at what the teachers says, about how they work and trying to achieve the goals of the curriculum in physical education.Framing of the questions? What does the teachers think affect and develop the teachingroll in the Waldorfschool?? How does literature describing the teachingroll/physical education roll in the Waldorfschool?? What does the teacher in physical education says achieve to, counter what the curriculum says about physical education in the Waldorfschool?? How does the teacher do to achieve the goals in the Lpo 94?MethodA literature research of relevant previous studies was made among others in the database Eric.Curriculum for the Waldorfschool and books about Waldorf pedagogics and the teaching roll has been studied.

Upplysning enligt IAS 36 : En kvantitativ fallstudie av två branscher

Background: Goodwill has been a hot and debated topic for a longer period of time. Researchers have debated how goodwill should be accounted for and have not come to a solution. In 2005 IFRS standards came which meant that goodwill no longer will be amortized according to plan, but to be put through a yearly impairment test.Problem: A number of disclosure requirements in the financial reports have been made in an effort to avoid companies to account for goodwill differently. Apparently there still is a problem of how companies account for goodwill and there are several studies in the subject. But no one has studied how it is between two different industries, which make this study interesting to execute.Purpose/questions: This study have the purpose to investigate how the industries day to day wares and health care regards the disclosure requirements for goodwill by the impairment tests.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Ombyggnad av flerbostadshus : Hur påverkas hyresgästerna av  en ombyggnad

During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction.

Grund plöjning med Kvernelands Ecomat och Ecomat Seeder : resultat från undersökningar genomförda år 2005

The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala. In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the seedbed, the number of emerged plants and weeds, the pentration resistance and the yield were examined. Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good alternative to conventional autumn ploughing when growing spring crops. During the season 2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm). In the other two studies, ploughing to different depth in the autumn with the Ecomat was compared with conventional mouldboard ploughing and stubble discing.

Analys av Termodeck som ett uppvärmningssystem : En jämförelse mellan uppmätt och simulerat värde samt analys om skillnaden för husets energianvändning

Ett passivhus är byggt av stomentreprenör företaget Strängbetong i Vara med ventilation och uppvärmning i samma system som kallas för Termodeck. Uppvärmningen sker genom att tilluft från ett FTX-aggregat förs igenom håldäcksbjälklag som värmer upp bjälklaget. Med det erhålls ett ?värmegolv och värmetak?. För ett sådant system behövs en byggnad med tung betongstomme.Energibalans beräkning har gjorts med IDA program och schablon värden från olika kravspecifikationer som visar simulerade värden.

TRIM : ? Metod för att identifiera risker och uppskatta projekttider

ITT Flygt is a world leading company that mainly manufactures submersible pumps. A problem of ITT Flygt is that product development projects rarely manage to hold the estimated project time. It shows that something unexpected occurs in projects quite often, which results in delays. The delays can both be due to an optimistic time plan of projects and risks in product development projects which are not discovered at an early stage. This added with unforeseen delays makes it difficult for ITT Flygt to estimate the duration of their projects.The goal with the Master thesis is to examine a suitable method for simulation of project time.

Risk för dehydrering och svält preoperativt.  : En kartläggning av preoperativa fasteperioden hos patienter med kroniskt subduralhematom

ABSTRACT The purpose of this medical record research was to study 30 patients with chronic subdural hematoma on a neurosurgical clinic, mapping documented nutritional status, preoperative fasting and hydration and energy supply before surgery. In addition peroperative administration of fluid and vasoactive drugs, as well as postoperative complications and length of hospital stay were studied. The mean age of the patients was 71 years. Nutritional status was evaluated in 12 patients, out of these seven were judged to be at risk for under nutrition. Fifteen patients had surgery day 1 (total fasting time on average m 11 h), eleven had surgery day 2(29 h), three had surgery day 3 (35 h).
