Energieffektiva principer : Påverkan på en villas arkitektur och energiprestanda
Kraven på att nybyggda bostäder ska vara energisnåla i driftskedet ökar hela tiden av flera anledningar. Dels vill brukarna hålla driftskostnaderna så låga som möjligt och dels är det miljöaspekten som spelar in. Men hur energisnål kan en villa egentligen göras och hur påverkas arkitekturen då den görs extremt energieffektiv?I den här rapporten utreds tio energieffektiva principer som kan användas för att göra en villa mer energisnål och energiproducerande. Alla tio principer har tillämpats i en villa som projekterats under arbetets gång.
Mål- och resultatstyrning inom domstolsväsendet: En fallstudie inom Migrationsdomstolen i Stockholm
The aim of this study is to enhance the knowledge of target and performance management?s effects on the judiciary. In the past decades there have been a number of reforms in the general public sector of many countries. The management philosophy often used to describe these public sector reforms is called New Public Management (NPM). One main theme has been an increased focus on the management control systems, for example a greater emphasis on target and performance management.
Kravanalytikerns roll : Kommunikationsförmedlare mellan olika intressenter i ett IT-projekt
According to statistics, requirements management is identified as a major source of error to failed IT-projects. Moreover communication is identified as a factor affecting the require-ments management and can lead to deficiencies in the requirements. The requirements analyst is responsible for managing the requirements from the different stakeholders, act as a com-munication accommodator and to translate abstract requirements expressed by users to more specific requirements that developers can implement. The purpose of this thesis is to study the role of the requirements analyst to investigate the problems that may arise in working with requirements management. To achieve the purpose we have performed a requirements management process in which we ourselves took the role as the requirements analysts. The requirements management process consisted of three phases: gather requirements, document requirements and validate require-ments.
Finansiering av vindkraft : fallstudie av Lau Vind AB
The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.

En jämförelsestudie har genomförts mellan två värmesystem. Analysen har genomförts med ett flerbostadshus som referensfasighet. Fastigheten är lokaliserad i Södertälje kommun. Analysen går ut på att bestämma vilket värmesystem som är fördelaktigt vid renovering av äldre flerbostadshus med avseende på energi och kostnad. De systemen som har behandlats är ett centralt värmesystem med motströmsvärmeväxlare och ett centralt värmesystem med frånluftsvärmepump.Det centrala värmesystemet (Eq aggregat) är ett centralt från- och tilluftssystem med återvinning (FTX system).
Strategic Human Resource Management-ett medel att förbättra kundnöjdheten i serviceföretag
Motivationsskapande åtgärder är avgörande för de anställdas nöjdhet inom organisationen. Vad som motiverar de anställda varierar från individ till individ. Vårt resultat visar att det existerar ett samband mellan de anställdas nöjdhet och hur väl organisationens strategi, struktur, utvärderingar och belöningar stämmer överens med olika karriärinriktningar och drivkrafter. Studien visar även att de anställdas nöjdhet påverkar kundernas nöjdhet med servicen..
Ett samspelt Samhall? En studie av ett avkastningskravs inverkan på en organisations interna styrning: A synchronized Samhall? A study of the impact of an imposed return-on-equity requirement on the management control mechanisms of an organization
The aim of this study is to examine and analyze how management control mechanisms evolve within an organization when a requirement of return on equity is imposed, as well as why the mechanisms evolve the way they do. A case study was performed on Samhall, a Swedish state-owned company, which has the aim to help people with disabilities develop by providing meaningful work. The framework provided by Samuelsson, defining five means of control in organizations was used to structure the study. Further, theories within New Public Management have been used to provide the reader with a proper background to the research area. Theories from the institutional field of organizational research have also been used to provide further depth to our analysis.
Mätning i nätstationer - nyttor och problem
The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.
Lumilos
Lumilos is a work investigating the possibilities to use light and color in an interactive design context.
I have explored different light sources and compared them to each other and given a short
description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms.
I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.
Content Management System i intranät : Open Source CMS som intranät
Idag har de flesta företag och organisationer någon form för intranät-lösning. Dessa lösningar kan vara både mer och mindre sofistikerade, men har oftast det samma syfte; att distribuera organisationens information till dess medlemmar.Denna uppsats ägnar sig åt intranät och fördjupar sig i ett begrepp som vuxit starkt de senaste åren, nämligen Content Management System (CMS). Jag fokuserar särskilt på val av Open Source CMS, för implementation i mindre organisationers intranät.Uppsatsen är ett resultat av omfattande litteraturstudier inom sitt område och bygger främst på vetenskapliga artiklar av ledande experter. Ytterligare en källa är resultatet av en enkätundersökning, som också redovisas i uppsatsen. Denna enkät hade som ändamål, att kartlägga användares attityder till deras CMS-intranät.Uppsatsens kanske viktigaste resultat är en redogörelse för hur ett moduliserad CMS-intranät skulle kunna utformas, baserad på bl.a.
Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Om vikten av kvalitet. En studie av förändring i svensk hälso- och sjukvård.
The public health care sector has come under increasing pressure to cut down costs, maximize productivity and satisfy patients' needs during the 1990s and onwards. As a way of "getting more for less" quality management has been introduced. Originating in the private manufacturing industry, quality management has a strong focus on productivity and efficiency, aspects which are measured in quantitative terms. However, there are strong concerns that quality management is a means of speeding up the marketization of public health care by introducing core values much different from the ethic and medical norms that traditionally underpin health care organizations.This essay focuses on how quality management has been introduced to, and transformed by, public health care. A theoretical framework based on new institutionalism is constructed, and translation theories are used as a way of illustrating how the medical institutional environment, in fact, changes the concept of quality management.
Värmeåtervinning på förskolan Rymdattacken 1 : En jämförelse av värmeväxlare
In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.
Matavfall från livsmedelsbutiker : - En analys av den kommunala hanteringen i Sverige samt en detaljstudie av förhållandena i Umeå kommun
Food waste from grocery stores - An analysis of municipal management inSweden and a detailed study of the situation in Umeå municipalityThe objective of this thesis was to analyze the municipal management of food waste fromgrocery stores in Sweden in general and in Umeå municipality in particular. Furthermore theobjective was to account for the different waste treatment methods that can be used and toevaluate them from an environmental perspective. In order to analyze the municipalmanagement a survey was sent to all of the municipalities/municipal waste companies inSweden. A general comparison of treatment methods was carried out on the basis of ascientific review and a system analysis was performed in order to compare three differenttreatment alternatives for the food waste generated in grocery stores in Umeå. The surveyshowed that the legal definition of food waste from grocery stores is unclear and variesbetween municipalities.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
