Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

The purpose of this study is to examine how adult students, studying at an upper secondary school for adults, search for information for their independent tasks in different subjects. These independent tasks are frequent in most subjects and are a part of the ?investigation-work?. For most adult students this is a new way of learning. Fifteen qualitative interviews with adult students have been conducted.

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company?s management considers that their follow-up process of cost accounts is not fully functioning.The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.

We have decided to conduct a case study of German and Swedish mid-level managers within the automobile industry. Primarily we used a qualitative method of investigation and a phenomenographical methodological approach in order to conduct an in depth analysis. We conducted semi-structured interviews with six mid-level managers each in Germany and Sweden. The semi-structured interviews allowed us to conduct flexible interviews which enabled these managers to speak relatively freely about their own view of leadership. Throughout our investigation we have based our results on the empirical findings and at the same time sought explanations to different phenomenon in relevant secondary data, such as management literature, thus used the abductive method of investigation..

The chief aim of this study is to investigate the impact of context on written peer response. A second aim is to explore students? attitudes towards peer response. The investigation has taken place at an upper secondary school in the south-east of Sweden, involving 20 students in grade 2 and 3 in the course Swedish C. The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.

This is the first investigation of the activity with feature film (video) in Swedish publiclibraries.Due to the Swedish copyright legislation, the activity with feature film in Swedish publiclibraries was not possible until an agreement was set between Kommunförbundet and SverigesVideodistributörers Förening in 1989.My investigation is based upon a form that I made in cooperation with Statens kulturråd.The form was sent to the main public libraries in the 286 municipals in Sweden. 250 (87 percent) of the public libraries answered the questions. 130 (52 per cent) of the libraries whoanswered had an activity with feature film.The main reason the libraries bought feature film, was that they hoped that feature filmwould attract new visitors to the library. The investigation also showed that high costs forhiring feature films has a negative influence on the lending of feature films..

This thesis takes its starting point in the 27 Chapter 1, section 1 of the Swedish code of judicial procedure, where the following is found:?objects reasonably presumed important to a criminal investigation or taken from a person through a criminal act or subject to criminal forfeiture may be seized?In this thesis we have investigated what kinds of problems occur when the seized object is part of an investigation of IT-related criminality. We have used methodological investigations of Swedish laws, legal usage, and the preliminary work with laws. Further have three interviews been made with different actors affected by or involved in seize of objects. These persons were a police officer, a public prosecutor, and a person whose object has been seized.The result we present is that there exist three kinds of problems related to objects that are seized within the demarcation of this study.

This work of investigation was to report how four study counsellors see upon the facts regarding the amount of admission, the students social surroundings and local designs for the Individual program (IV) at upper secondary school. Through interviews with four professionals set to guide the students at four different schools in the rural districts of Boden, Luleå, Piteå and Skellefteå, this has become a paper that describes how they see these young adults today. Different handicaps and diagnosis, troubles at home, pregnancy and even drug abuse tend to make you wonder how they possibly can get through school at all. Regarding local development within the program there are no strings of what to do but for every district to deside for themselves and this has led to different ?experiments? with students not mentaly fit for school at all.

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Environmental issues is now taking a growing place in society and to ensure that companies meet public expectations and do their part in working towards a sustainable development, environmental management system is said to be an effective tool (Almgren & Brorson, 2009).This case study has examined a company's environmental management system in order to find strengths and weaknesses within the ISO 14001 system. The work was carried out using interviews, document reviews and analyzes in which the three main concepts control the report ; "daily work", "audit" and "environmental aspects".The results shows that the daily work looks different depending on where you are; in the production or at the office. The audit examined all documents related to the environmental management system and the study showed that the biggest strengths was the commitment and waste handling while areas such as environmental goals and management review needed improvement. As a result of the deficiencies identified, suggestions for improvements was proposed. The investigation of the routine of the environmental aspects showed an incomplete routine where the red wire from identification to evaluation was missing.

Work has a great influence on most of individuals in society. It influences both identity as well as the structure of the day. Unemployed people are often affected in a negative way through economic and psychological problems. In order to help people with reduced work capacity back to the labour market and decrease unemployment, the Labour Market Board works with vocational rehabilitation. The aim of this study is to investigate experiences of vocational rehabilitation within the Labour Market Board among unemployed people.

In the field of IT-forensics you may often get to analyze different types of digital devices. One ofthese devices is the GPS navigation system.
