When constructing an industrial- or hall building, the most common framework materials thatis used are wood, steel or concrete. Due to an assignment from Byggnadstekniska Byrån ABhas a document been created that makes it possible to investigate how the final costs is af-fected by gapes in between elements and which used foundation. And this with steel as thematerial. The purpose with this essay is to investigate which is the most well fitted materialwhen constructing an industrial- or hall building wood, steel or concrete. Information aboutthe different materials has been collected by litterateurs and by different internet pages.

Background: Following an increased awareness concerning social and environmental aspectsin society, more enterprises establish sustainability reports in order to inform theirstakeholders about the company?s sustainability duties. A previous study indicates that themetal sector is enjoying relatively limited increases in business opportunities and/or financialvalue of corporate responsibility. Another study suggests that there is a gap in expectationsbetween producers and users of sustainability reports due to an uncertainty regarding whatinformation such reports should contain and what audience such reports should target. Thequestion is whether or not a gap in expectations concerning sustainability reporting is acontributing factor to the limited increases in financial value in the metal sector?Purpose: The purpose of the study was to examine how a sustainability report should becarried out by a company in the Steel industry given what information the company and thestakeholders consider as essential in a sustainability report.Methodology: To accomplish the purpose of the study, a deductive approach was used due tothe availability of suitable theories.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the Steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the Steel industry has reduced its energy consumption per ton of steel produced by 50 percent.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Our starting point has been to examine how a project manager without knowledge of the industry is able to plan a project. And also which difficulties that may arise. A qualitative study was conducted at project managers who worked in the construction industry and events industry. Seven interviews were conducted, four in the construction sector and three in the events industry. Respondents are active as project manager in Värmland and Närkes counties.

The telecom and the IT-industry are converging, which creates new possibilities and threats for both existing mobile handset vendors and new entrants originating from the IT-industry. The purpose of this thesis is to explain how IT-players? entrance in the mobile handset industry affects the industry in regards of key success factors and value chain structure. This study has used dynamic theories to describe the mobile handset industry. The theories have helped us in understanding the characteristics and drivers of the industry and thereafter to identify the key success factors.

This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error. .

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.

At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.

Atlas Copco Secoroc tillhör en av de tre ledande tillverkarna av bergborr- verktyg. Sandvik Steel har under en längre tid varit Atlas Copco Secorocs enda leverantör av hålvalsat borrstål. Samarbetet mellan företagen har lett till specialiserade produkter och en relation som är svår och tidsödande att bygga upp med en ny leverantör. Relationen har dock blivit påfrestad då leveransprecisionen från Sandvik Steel inte är tillräckligt hög. Den låga leveransprecisionen medför att Atlas Copco Secoroc får svårt att leverera sina produkter i tid.
