Design av motorstyrd lyfthjälp till toalettstol

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

Hur påverkar ålder och fetthalt laxsmoltens utvandring till havet?

AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.

När ska dieselelektrisk framdrift av fartyg väljas?

Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.

Första mötet med förskolan : en kvalitativ studie om olika inskolningformer på fyra förskolor

This is a qualitative study with four interviews, in four different preschools, in the same municipality. By making it so, it becomes a case study to describe a phenomenon in a municipality which also is the definition for this investigation. The purpose of my study is to examine what it means, in a municipality, to have different types of introduction at preschool. Where I ask the question why preschools choose to have a specific method of introduction and what are the basics and ideas behind the choice of the method? What significance do these different methods have to attachment theory? What do teachers think about the advantages and disadvantages with their choice of method?The versions of introductions are many and may vary; the duration of the introduction may vary from 1-3 days up to 3 weeks.

Ränteavdragsbegränsningar : En analys av nuvarande ränteavdragsbegränsningar och  alternativa metoder

Interest deduction limitation rules have an important function as the regulations prevent the Swedish tax base to decrease. However, the restrictions must not be at the expense of the business environment. Interest deduction limitation rules that do not work in a satisfactory manner are likely to make Sweden a less favourable country to establish in. The first Swedish rules which were aimed to restrict interest deduction threaded into force in 2009. The rules were applicable to intercompany loans related to acquisitions of part ownership rights and the aim was to reduce tax avoidance through corporate group-loans. The rules proved to be ineffective since the avoidance continued and the Swedish rules could not tackle the problem.

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Läcksökning med penetrant ? kvalitetssäkring av

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Bullertunneln : En utredning kring en ny bullerlösning vid trafikleder

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

Är verkligheten indelad i ämnen? - en undersökning av elevers upplevelser av ämnesövergripande arbetssätt i tematisk form

Our purpose with this essay was to explore students? experiences of interdisciplinary working method in thematic form. With a starting point from Lpf-94, the curriculum for the upper secondary school and several theories of learning, we wanted to explore if interdisciplinary working method in practice could create an environment for a meaningful learning situation. The study took place in an upper secondary school class, study preparatory, third grade, who works interdisciplinary in thematic form. Our study was qualitative and we used an open structural questionnaire where the students confidentially were able to describe the working method, explain which subjects that participate in the work, and bring forward good respectively bad factors about the method.

När delar blir till helheter eller helheter blir till delar : En studie om olika läsinlärningsmetoder

AbstractThe present thesis examines reading acquisition. The aim of the study is to gain a deepened understanding of various methods used for reading acquisition, how teachers? are dealing with these methods and what aspects require special attention. The overall research question of the thesis is: How can one assess children?s future reading ability and identify a method that is appropriate to this ability? The overall aim leads to several more specifically addressed issues.In the theoretical part, different perspectives and theories about reading acquisition are presented along with different methods for how to work in order to facilitate reading.

Returhantering vid LensLogistics AB: en process- och
flödesutredning för förbättringar

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

Change Lab : Att arbeta med lärande förändring

In order to be able to change, to maintain competitiveness as a company in a world where rapid changes is part of the daily life, it is crucial to have knowledge and methods in how to change. One method, originally developed in Finland, is the Change Laboratory. This method is said to be efficient, not only concerning change aspects but also learning, since change and learning in this method is intertwined. This Master Thesis (20p.) tells about the process of conducting a Change Laboratory with a Swedish high-tech company and analyses factors in the process that makes change possible..
