The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

AbstractReading books to children is often an integral part in preschool activities. The purpose of thisstudy is to investigate how educators think about the educational function of literature inpreschool activities. I have in my study used qualitative interviews with active educators andobservations to answer my questions about why the educator reads to the children, how theeducator thinks about the choice of literature and if the literature can contribute to thechildrens development and if so, how. The knowledge- and research background presentsliterature and previous research done on the subject. The results of my study shows that theeducators have many thoughts about the importance of literature in preschool.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

According to statistics, a significant increase in sickness has occurred in the public sector in recent decades in Sweden. Human therapeutic professions is the area where the illness is most prevalent. The purpose of this study was through a qualitative method and hermeneutic approaches explore how conscious six social workers in the social services are on stress and how they cope with it. Further it investigates and analyzes how these results affect their daily work.One important result due to stress is that the social workers ability to treat their clients is impaired and they are less able to be empathetic. Inadequacy in the work environment leads to a sense of insufficiency by social workers, and a reduced quality of life.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

The purpose of this study is to investigate how teachers approach communication in their mathematics instruction. The communication involves concepts such as teachers' mathematical language, incorrect answers, and various interaction patterns. In line with this, the study also examines how these types of communication may affect students in the classroom. Furthermore, observations and interviews were conducted with five different teachers in Sweden using an observation scheme and an interview guide. The results reveal that four out of the five teachers use both child-directed and adult-directed language when addressing students at different levels of mathematical understanding.

According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for producing ethanol and is the leading producer and exporter of fuel ethanol. My purpose with this paper is to investigate why Brazil decided to develop ethanol production on a large-scale operation and to find out today?s situation. Focus will mainly be on ethanol production with sugarcane as a feedstock.

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

During my practical training I have seen what after-school offers children. Large groups of children and little staff, often results in that the children had to play freely until they go home. Few activities are offered to the children and the staff is busy looking after the children and ensures that they are not fighting.The purpose of this study is to find out how children feel about their leisure activities and if they think they are being offered a meaningful leisure. The main research questions were:How do children experience their leisure-time?Do after-school offers children a meaningful leisure and is it the children's interests and needs that govern the activities and the environment?How do the number of children in the leisure group affect the leisure time?The methods to collect data in the study are observations and interviews.

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

Swedish municipalities' websites contain vast amounts of information that caters to a broad audience. For users to be able to access this information, it is important that the website is accessible, to everyone. 74 percent of people with disabilities states in a survey conducted by the Swedish Agency for Participation (2015a) that they use the internet to make contact with local municipalities, but simultaneously more than 1 out of 10 experiences difficulties associated with the use of computers and the Internet, according to Statistics Sweden (2014). The purpose of this study was to identify how Swedish municipalities are working to make their website available for people with disabilities. The study also examined what municipalities should do to make available their website and what difficulties are in the process of making a municipal website available. In working with this survey people who have insights into the subject and seven community representatives were interviewed.

AbstractIn the secondary-school program for hotel and restaurant complete courses or parts of courses are placed in workplaces so called workplace education (APU), this means that the content in the course plan must be discussed and be divided in a proper way between the school and the workplace, so that the students is gaining all the parts that is prescribed in the goals for the course.Interviews with tutors and teachers have been performed, with the purpose of investigating how the collaboration between the school and the workplaces should look like so that the APU fulfills the content and quality that are prescribed in the specifications of the education. The study shows that a better structure for collaboration between the school and the workplaces is needed. Lack of time and financial resources are the factors that according to the study reduces the possibility?s to (among other things) perform education of tutors, and for the teachers to plan and follow-up the APU-period..

I examine how relationships between people and objects are created and continues through contiguity every time one use or touch an object and through participation through use and memories. The aim is to continue a relationship and to keep a communication alive with people beyond time and space, then, now and henceforth. I take advantage of and transform the traces in an object that belonged to someone. Parallel I create new space for bodies to put their mark for the first time. I compare my work with the Nordic Museum's task to preserve the present for the future.
