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 thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

The purpose of this study was to find out how caregivers experienced their psychosocial work environment at three municipal homes for old people. The Copenhagen Psychosocial Questionnaire (COPSOQ) was used in order to study different dimensions of the work environment, and questions about health, sickness presence and sick leave were included. The questionnaire was answered by 86 out of 112 participating caregivers (77%). The results showed that the caregivers experienced high demands at work. The degree of feedback and influence at work was low, but they reported that their work was highly meaningful and that they usually received social support at work.

Incident response plans are faced with new challenges as organisations expands to the cloud, this thesis aims to highlight these challenges and their potential solutions. Our work has focused on managing the incident response in contrast to earlier work that has been focusing on preventing them.As with any development, security is seldom prioritized. Instead the focus are often aimed towards usability and functionality, which means incident response plans are written, implemented, forgotten and finally becomes obsolete. This could result in an organization losing their ability to produce acceptable forensic images, avoid severe downtime, or prevent similar incidents in the future, which are all important parts of incident response.Traditional incident response plans does not address incidents in the cloud. Thus, an absence of guidelines for managing incidents in the cloud becomes apparent.

A current issue today is to try to implement creative design as a way to solve wicked problems in scientific contexts such as HCI. Since the problems are wicked, they have no given solution which makes the traditional methods inadequate. In these cases, creative design can be an alternative. Creative design is not used in scientific contexts because it is viewed as something unaccountable.In this essay we argue that creative design not necessarily have to be unaccounted. We discuss various views of creative design and translate theory to a practical context.

The basic view on children has change radically in the swedish society during the last century. From beeing seen as ruled by internal evil powers that only church could help controling later on the children should be brought up as citizen well-behaved and capable of work with help of the state's control. Today we see the child as competent and equal, and through Swedens adoption of the U.N. Convention on the Rights of the Child in year 1990, Sweden as a country undertakes itself to always see to the child´s greatest in all decision-making process concerning the child and also vouch for that the rights stated in the convention are beeing fulfild.Working with the convention in a such way that it's intention becomes reality in educational activities requires instruments for the pedagogues. During the years between 1980 and 1990 a number of different methods and programmes were developed with staring-points in the interplay between the child and the adult.

The aim of this essay was to acquire an enhanced knowledge about young immigrants? point of view of integration. During a former practical training semester I became interested in what the young immigrants thought about their own integration, what their conception was about this issue. I found that it had different meaning to different persons, to some it meant assimilation, to others it meant being able to interact with the opposite gender. To examine this I used interviews and interviewed an amount of young immigrants in different stages of their studies in Swedish.

This paper is about employer?s obligation to establish plans for equality between the sexes and the practical use of these plans. The aim is to clarify what national and international law states about plans for equality between the sexes, and to examplify how plans for equality between the sexes is used in practice.For this paper juricprudential metod with a social science perspective is used. Current law has been examined, but this paper also contains an empirical part consisting of interviews with two individuals from a municipality and a private company, and an examination of the two organizations? plans for equality between the sexes.Employers with over 25 workers owe to establish a plan for equality between the sexes.

The study aims to increase understanding and knowledge of motivation; this by examining how the leader experiences her capability to promote employees' work motivation.
