Utveckling av lastmodell för Uppsala fjärrvärmenät

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

There is a need of information about these new species and their hardiness. The insufficient information about the subject has been the background to this work.

Title: Change Communication within organizations ? How perceptions differ between managers and employees in an organizational changeAuthor: Emma Ender & Fanny TeschTutor: Anne-Marie MorhedPurpose: The purpose of this thesis was to study and compare different perceptions of change communication between managers and employees within two smaller organizations. We wanted to examine how the communication process within the change was carried out. We also aimed to compare the results with change communication models of Johansson & Heide (2008) and Lewin (1951), and also existing concepts, to see if our result differed from earlier research. Our key questions to answer were: How do managers communicate a change to the employees in two smaller companies? How do the managers think that the employees perceive the information about the change? How do the employees perceive the information about the change? How does change models from previous research correspond to, or differ from the change process?Method/Material: The material used in this thesis consists of a total of twelve interviews with both managers and employees at two small companies.Main results: The main results shows that communicating a change is complex, and that it is difficult to create models and theories for the phenomenon, as each change is unique.

Att identifiera signaler för obestånd i tid

To be able to protect themselves from credit risk, the banks must constantly check the performance of  the companies they have lent money to. There are many mathematical models for predicting financial distress. These models use accounting-based ratios, which often are historical and not representative for the present situation. This study describes how the banks do in practice to find signals of insolvency in time and the variables they are observing for doing that.In addition to financial reports which the company sends in to the bank at least once a year, also the relationship between them and information from different information  agencies are of great importance to track  signals of insolvency. Poor profitability is the primary cause of insolvency.

Studentsupport en studie om dyslexi, hjälp till dyslektiska studenter och deras upplevelse av hjälpen

The aim of this thesis was to describe the services offered to students with dyslexia, and from a service- and quality perspective describe how the consumers of these services experienced the supplied services. Dyslexia refers to certain problems with the written language. With the demand for students in higher education to accumulate much knowledge through reading, this becomes a question of vital importance. A qualitative descriptive approach was used, and a case study was conducted. The case study covered 'Student support' at the University of Borås and how dyslectic students at the university experienced the help from 'Student support'.

Som små astronauter : -En idrottslärares berättelse om specialgymnastik i skolan

The aim of this work is to examine methodologies at remedial lessons for children with weak mobility, in a common Swedish municipal school in an attempt to determine if a connection to theoretical learning exists.Kadesjö describes how difficulties in concentration can arise as a result of problems with mobility and perception, and according to Piaget very young children develop cogitation through physical movements. These connections are not news but always current.At the meeting with Lasse the question was born whether learning problems in school that are a result of concentration difficulties, could be countered with mobility training.By the selection of Life history as method, it?s possible to follow a physical educator's experiences through his 30 years of work, and to some extent even his private life. Experiences and results are notified from a historical perspective from 1976 until 2006.He is bringing us on a journey that shows the changes in methodology and results after his contact with Sensomotoriskt Centrum..

Manliga förebilder inom socialt arbete : föreställningar, praktik och organisation

Among those who graduate from the various schools of Social work in Sweden are a great majority women. At the same time men are sought after in the work field.  But not just to level up the equality between the sexes, but also to fill a gender specific niche to counter up a need for male role models. But a closer look at this need and the types of functions set to cater for it shows that male role models as a concept vary between contexts. In this study we examine the concepts and the practices of male role models in three different settings: a municipal social care center offering young boys male bonding activities; a non-profit organization warding young people from drug abuse and criminal behavior; and last, a long term residential home for young boys between the ages 13 and 19. Our research shows that the concept of the male role model vary between the organizations and less so within.

Sånger från graven: En kartläggning av krafterna som hämnar den digitala revolutionen inom svensk musikdistribution

Songs from the Crypt: Mapping the Forces that Hinder the Digital Revolution of Music Distribution This paper seeks an explanation to the low market share growth of the commercial digital music distribution in Sweden. The analysis identifies a spectrum of obstacles that hinder the digital distribution technology from becoming the main form of music distribution in Sweden. These obstacles make the digital music distribution less favourable in comparison with physical distribution from the consumer?s point of view. The authors suggest that in order for the digital distribution of music to become competitive the digital product would either have to be developed further to offer more customer value or the so called a là carte retail model would have to be replaced by a subscription-based distribution model.

Data och Tv-spel : Data och tv-spels påverkan på ungdomar

The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.
