Energikartläggning av Försäkringskassans lokaler : rekommendationer för ett fortsatt energieffektiviseringsarbete

With new energy directives in place, the Swedish Social Service (SSS) stands beforethe challenge how to reduce the energy demand in its locales. It is a complex matter,as the locales are rented from various property owners and it becomes a question ofhow to reduce the operational electricity and influence the property owners to workmore with energy efficiency. This thesis takes a balanced research approach in threeparts. Firstly a qualitative part in form of interviews with personnel at the SSS and itsproperty owners, secondly a quantitative part of descriptive nature in form of energystatistics and thirdly a literature review of Energy Management (EM) Supply ChainManagement(SCM), Green Supply Chain Management(GSCM) and EnviromentalPerformance Indicators (EPI). This in order to be able to give normativerecommendations of how the SSS should act to reduce its energy consumption in itslocales and provide new insights on how EM, SCM, GSCM and EPI can be applied ineffect.

Value creation- How can companies optimize the human capital

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Eurocodes : Beräkningsjämförelser mellan eurocodes och BKR

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.

Modellering och simulering av det evaporativa bränslesystemet i en personbil

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Effektivt eller modernt utvecklingssamarbete? En organisationsteoretisk analys av 1990-talets svenska biståndsorganisation

The focus of this essay is Swedish bilateral development aid. With the help of organization theory I analyse the development aid strategies and policies of the 1990s, in order to examine how and why they were introduced. I investigate three different types of aid organization, namely structural adjustment programmes, political conditionality tied to aid co-operation, and equality policy as part of development co-operation. I analyze the introduction and subsequent use of these three co-operation forms to see whether they were applied and adopted into Swedish development aid because more efficient measures were required or because they were the most recent and modern ways of dealing with development co-operation.Organization theory presents these two ways of analyzing organization. They are occasionally competing and sometimes complementing each other in explaining organization.

Fireball 2 : Energieffektiv fiber produktion

The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.

Lagerhantering på Voice AB

This examination paper is a lead in the educational program Industrial Management at Jönköping University. The paper itself contains an analysis of the warehouse organisation and its efficiency at the furniture company Voice AB in Torsvik, just south of Jönköping, Sweden. The report also contains propositions to raise the level of efficiency in the company warehouse and warehouse management.In the investigation of the warehouse a number of possible improvements were found. Examples are lack of a system for labelling shelves and racks, lack of an efficient location system and development possibilities in work routines. For the empirical investigation both qualitative and quantitative methods ware used.

Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Handelsstopp på Stockholmsbörsen. Innebär handelsstoppen på Stockholmsbörsen en trygg handel och en effektiv marknad

This paper examines if trading suspensions on Nasdaq OMX Nordic - Stockholm work as a contributing factor in creating a secure trading. This has been made through an event study and examination of abnormal returns. Our results for plus tick suspensions indicate that suspensions fulfill their purpose in creating a more secure trading since the trend of abnormal return we observe prior to a suspension is disrupted. Thus, the suspension is warranted. The conclusion is that the market cannot be completely safe; as the law and practice is structured today an abnormal return is inevitable.

Nötköttsproduktion i Västerbotten

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

Direct-EGR tillämpat på HCCI

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Central and Eastern Europe

An increasing number of automotive supplier companies are investing in Central and Eastern Europe (CEE) in order to gain cost advantages. This has happened in a rapid pace since many of these countries did not have any foreign direct investments (FDI) at the turn of the century. The problem now is for how long these countries will be able to maintain the low costs. One purpose was to create a model of country advantages for automotive supplier companies when relocating further production to CEE. This dissertation was written in cooperation with the Trelleborg Group.
