Förskolor med passivhusteknik : En utredning av passiva förskolor

As a result of directives from EU, with the ambition to reach environmetal goals, The German organisation Passivhaus Institut has defined a passive house. A passive house is a building that is very energy efficient and makes a small impact on the environment. The energy from the inhabitants as well as the appliances & fixtures in the building should equal the energy that is required to heat the building. A Swedish version of the passive house definition has been defined, taking into account the climate conditions and the difference in building regulations.This thesis is a request from Skanska on how it can improve and develop an ongoing passive house project, involving an infant school. The intention of this thesis is to identify difficulties & display potential development areas for infant schools.The method of research conducted is as follows: interviews of clients, ventilation consultant, consultant for heating system and an energy calculation consultant, an inspection of the infant shcool in process, investigation of completed infant schools and a study of relevant literature.From this research it was found that it is difficult for infant schools to pass the criteria for passive houses. The conclusion of this thesis provide several guidelines on how to improve the outcome of existing projects & the steps needed to be taken for future development in this area..

Tydligt men komplicerat - om upplevelser av ledningssystem

De flesta företag använder sig av något slags system för att kontrollera arbetsflödet. Dessa system används av alla på företaget och därmed är det viktigt att undersöka, hur medarbetarna upplever detta system. Med en explorativ utgångspunkt gjordes en enkätstudie på ett företag i Västsverige. Resultatet visade att deltagarna, förutom några få procent i stort sett hade liknande positiva upplevelser. Ingen skillnad fanns heller mellan grupperingarna ung/gammal eller antal år de arbetat på företaget.

Systematiskt brandskyddsarbete med Hallsta pappersbruk som tillämpningsexempel

The aim of this report is to improve the fire safety at Hallsta Paper Mill in Hallstavik, Sweden. In order to do so large parts of a fire-protection management system for the paper mill has been created. The report begins with giving a general description of management structures and fire-protection management systems. An account is given for how management structures are designed, and how they should be implemented, maintained and updated. Thereafter follows a description of what routines and instructions should be included in a fire-protection management system..

Koncernchefens : Rättsliga ställning och interna skadeståndsansvar

At first glance, the group CEO's (koncernchefens) legal position looks easy. It is the CEO?s responsibility to lead and make decisions on matters which affect the entire group, all while defending the company?s best interests. However, when one looks closely at how the Companies Act (Aktiebolagslagen) regulates how a company should organize itself, as well as the options available to manage the group, one rea-lizes that simply appointing a group CEO does not necessarily make the company compatible with the Companies Act. A group CEO threatens to reduce both the Board and CEO's legal administrative districts which are not in accordance with legal and commercial principles.In order to introduce a group CEO it requires a detailed investigation of the group's legal relationships.

Inkludering som mål för skolan specialpedagogiska arbete : Ett dilemma mellan styrdokumentets direktiv och verkligheten i klassrummet

The society?s view of pupils with needs of special support in nine-year school has changed over time in Sweden. The teachers? views of the pupils have had an influence of how the special education process is designed. The aim with my paper is to make a comparative study of how special education teachers in rural schools and schools in Stockholm have designed their work with pupils with needs of special support.

"Som om barnet heter Kalle" : - En studie av mottagandet av ensamkommande, asylsökande barn i Sverige 2008

 The 1st of July 2006 Sweden made a change of authorities in the system concerning the reception of separated asylum seeking children. Prior to the change, the Swedish Board of Migration was held completely responsible for the reception of these children, who arrives in Sweden without their parents or any other relatives to care for them. Since the alteration of the law (1994:137) the responsibility for the housing of these children now lies within the Swedish municipalities, while the Board of Migration still handles their legal commissions. The change was intended to fundamentally improve the conditions under which these children were taken care of. However the implementation took a severe wrong turn when the municipalities weren't prepared for their new responsibilities and the immediate result was alarming. This qualitative study is based upon interviews with the people responsible for the reception of the separated asylum seeking children in the municipalities of Kronobergs County, as well as one of the two people in charge of the new system at the Swedish Board of Migration.

Generellt mät- och styrsystem

Examensarbetets syfte var att skapa ett generellt mät- och styrsystem som är möjligt att fjärrstyra över Internet. Systemet består av en kontrolldator och ett antal separata moduler, vilka var och en realiserar någon typ av mät- eller styrfunktion. Användningsområdet för ett sådant system är brett; det kan exempelvis användas inom automation av bostäder, för process-övervakning och styrning inom tillverkningsindustrin, eller inom under-hållningsbranschen.Eftersom ett fullt utbyggt system kan bestå av ett drygt 100-tal olika mo-duler, är det här examensarbetet av praktiska skäl begränsat till att rea-lisera en handfull av dessa. Då systemet är enkelt att skala upp, är den be-gränsningen i antalet realiserade moduler i prototypsystemet inget som påverkar de erhållna resultaten. Exempel på storheter som kan övervakas är temperatur, avstånd, lufttryck och ljusstyrka.

Varför och hur integreras medier med svenskämnet? : En kvalitativ studie av tre pedagogers uppfattning om inkluderande arbetssätt

This essay is about why and how the media is integrated with Swedish as a subject. The purpose of the study is to investigate if the teachers who use different media when teaching Swedish consider that this pedagogy develops the students? learning. I also aim to find out if there are any differences and/or similarities between the teachers.To fulfil the purpose I have done a qualitative study with three teachers who work at a school. I have focused on following issues: How, when, where and why do the teachers use media when teaching Swedish?The investigation shows that media is popular today and it is becoming more so all the time.

Analys av fördelningssystem för bostadshus

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

Stubbtransporter och bränslekvalitet hos stubbved :

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

Betesdrift vid automatisk mjölkning i ekologisk produktion :

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

TOMO Hugglink

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Energiomställningens konflikter : en studie av bergvärmetrenden i Uppsala 2010-2011

Den här studien beskriver en konflikt kring en bergvärmetrend för bostadsrättsföreningar som uppstått i Uppsala under hösten 2010 och våren 2011. Konfliktens parter är å ena sidan bostadsrättsföreningar som valt att satsa på bergvärme för att i första hand minska sina uppvärmningskostnader från fjärrvärmen. Å andra sidan majoriteten i Uppsala kommuns miljö- och hälsoskyddsnämnd som är oroliga för trendens miljömässiga effekter, framförallt för elförsörjningen, och förespråkar fjärrvärme. Utifrån två teoretiska perspektiv har jag satt konflikten kring bergvärmetrenden i ett större historiskt och samhälleligt sammanhang. Jag har prövat möjligheten att se konflikten som en konflikt kring fjärrvärme som ett stort tekniskt system med referens till teknikhistorikern Thomas B. Hughes.
