Skadliga nollflödespunkter i Fortum Värmes fjärrvärmenät i Stockholm : En analys av dess förekomst och effekter

When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.

Konstruktion och programmering av lerduvekastare

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms.

Klinikintern statistik : en fallstudie kring behov av och möjligheter till framtagandet av ett statistikverktyg

The health care sector is one of the most information-intensive institutions in Sweden. Big investments in information technology have been made to ensure efficiency and quality within organisations in health care. This has led to high requirements in documentation and resulted in an increase in administration which gradually more often is done by nurses and doctors. A major problem is that it is difficult to gain access to the information recorded in all the different systems, which is their objective. This causes double documentation instead of being a support in follow-up performance.

Reducering av effektförbrukning i inbyggda system med Linux

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Taluppfattningstest med enstaviga ord i brus: Normalvärden för barn i åldrarna 7, 10 och 13 år

Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

Biblioteks- och informationsvetenskapens överordnade identitet : ämnets betydelse för studentens yrkesinriktning

Library and information science (LIS), being a research area characterized by theoretical discord and definition disarray, provides an interesting field of inquiry. Its content, boundaries, scope and superior identity are not clearly stated. This Master s thesis focuses on a thus far unexplored perspective on the discipline: a conceivable statistic and causes- and- effect relationship between the LIS students appreciated identification with the superior identity of the discipline, and the chosen vocational direction within the field. This relationship is examined through testing a working hypothesis on the results of a major quantitative questionnaire survey. The theory behind our research derives mainly from Thomas Kuhn and Richard Whitley.

Gränssnittet BarnOPAC barnens stig in i bokskogen: En användarstudie av hur barn uppfattar och hanterar ett svenskt gränssnitt.

BarnOPAC is a Swedish library interface for children. It was launched in public libraries in Sweden in 2001 and has now become a part of library software equipment in several public libraries. The purpose of the thesis is to investigate the interface BarnOPAC on the basis of the childrens perspective. The questions raised consider: how children experience and handle this interface, how library staff experience it and what viewpoints librarians have on childrens use of it. For this purpose we implemented a user study including eight children using the interface in a school library.

Spelifiering : En fallstudie med fokus på framställning och slutgiltigt värde

This bachelor thesis is an exploratory investigation about the phenomenon 'Gamification', which by some definitions is about implementing game elements into non-game contexts. For example exercise services as Runkeeper and Nike Plus who both are available on android and iOS platforms. This study is mainly about the potential value of gamified systems and services for companies and its users and how such a system or service is developed. The thesis also discusses the development aspect of gamified systems in order to give the reader a more ?in depth? understanding about the phenomenon.

Konstruktion av steghållare till brandbilar

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

Konstruktion Signalgenerator

SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.
