Användbarhetsutvärdering av det lätta sandwichmaterialet Hybrix för bilkarossapplikationer

This M.Sc. thesis is a material application evaluation commissioned by the advanced body engineering department at SAAB Automobile AB. The purpose of the thesis is to evaluate implementation of the innovative sandwich design material Hybrix into an automobile body. Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.

Underlag för BREEAM-certifiering : Kristianstad Nya Galleria

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.

Ett kognitivt branschperspektiv : Bemanningsbranschen

Background: The way in which corporate managers interpret, reason and evaluate uncertainties and constant changes, and how they take advantage of their experiences and wisdom can make a big difference for the long term survival of their companies.

In Sweden, employee recruiting industry has grown concurrently with the changes in the Swedish economy. Purpose: The purpose is to better understand the recruiting industry by performing a theoretical evaluation from a cognitive perspective. Delimitation: We intended to study the cognitive characteristics of the Swedish recruitment industry.

Allmänhetens inställning och riskperception gentemot stålverk : En enkätstudie

Stålindustrin förser såväl människor som samhället med många nödvändiga byggstenar. I Sverige finns tolv ståltillverkande anläggningar och hela 80 % av stålet exporteras. Som alla andra tillverkande industrier har den flera miljöaspekter att ta hänsyn till, men stålets nytta väger tungt och därför är det av stor vikt att genom forskningsprojektet Stålkretsloppet nå hållbar utveckling. Miljöskyddslagen, miljöbalken och ett ökande miljöengagemang har lett till arbete med miljöfrågor. Syftet med den här studien var att undersöka hur allmänhetens riskperception, attityd och oro gentemot stålindustrin ser ut.

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Personliga nätverk: en fallstudie om personliga nätverk inom musikindustrin

The purpose of this thesis was to illustrate the connection between personal networks and entrepreneurial business in the music industry. It also aims to examine how and why entrepreneurs in the music industry use personal networks in their entrepreneurial business activities. In order to explore the extent to which entrepreneurs in the music industry obtain support through personal networks, a case study was conducted based on interviews with entrepreneurs in various areas of the music industry. The study has shown that entrepreneurs in the music industry clearly see distinct advantages through the use of their personal networks, especially in terms of an enhanced supply of resources and through an increased amount of business opportunities. Personal networks have also shown to constitute a considerable amount of moral support for the entrepreneurs in the development process of the entrepreneurial business.

Som man ropar får man svar. En studie om kvinnligt ledarskap inom filmproduktion

The movie industry in Sweden is seen as a tight holding cluster where the different entities are being highly dependent on each other. There are also many different barriers to get a movie fully financed, and with the people in charged using arguments such as ?quality?, which is not objective but in fact subjective. The aim of this essay is to investigate how the leadership of five female film producers is being constituted in the film industry, an industry which is both close to the pool art and the pool commerce at the same time at it is male dominant. We have found that female film producers tend to use the strategy to adapt to the surroundings ?shouts? and ?demands?, at the same time as they adapt to their environment by becoming/not becoming entrepreneurs..

Process optimization in the steel plant

Blast furnace is the heart of every steel plant. Steel production is based on the blast furnace process, as it is where the iron is extracted from the iron ore and turned into liquid iron, which will subsequently be used to make liquid steel. Therefore, without hot iron, steel can not be produced. Blast furnaces in this process are supplied among others with pulverized coal. Raw coal should be prepared for the blast furnaces in the form of fine coal powder.

Finansiella värderingsmodeller : En empirisk studie

This study tests two financial valuation models empirically by valuing three stocks from three industries, with the purpose of studying how well valuation models work empirically and to make a forecast. The models which will be tested are residual income valuation and discounted cash flow. Nine stocks will be picked strategically from the Swedish stock market and additional analysis will follow in the analysis chapter.Based on analysis and valuation, the commodities industry has decent valuation as the healthcare industry is undervalued thanks to the high valuation of AZN. The energy industry has low value due to the capital intensive nature of the industry. When it comes to the models and their practical implementation, DCF has been the most problematic to apply empirically whereas RIV was better but it still shows extreme values, which teaches the student the clear difference between theory and empiri..
