Ovako Steel AB i Hofors tillverkar varmvalsade rör. Ett av de sista stegen i tillverkningsprocessen är en konventionell valsning i ett antal valspar kallad reducervalsning. De valsade rören uppvisar ibland en ojämn väggtjocklek längs rörlängden på grund av att det uppstår drag- och tryckspänningar i rören mellan valsparen. Syftet med examensarbetet är att öka kunskapen om dessa spänningars inverkan på det färdiga röret samt ge förslag på hur processen kan förbättras. I examensarbetet har undersökts vilka parametrar som påverkar spänningarna i valsningsprocessen.

Logistics planning for a construction site is usually limited by traffic flow to and from the workplace. The geographical location of the construction site is determined by roads around the workplace and opportunities for well-functioning logistics. Inventory of material is often impossible because of the frequently small workspaces. As a result, a concern relating material handling remains . Even before the establishment of a construction site, it is required in the construction industry to eliminate errors that might arise in the planning stage.

During the last decade, the construction industry has focused on improving and optimising its production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.

Today, buildings utilize 40 % of the total energy consumption. New energyrestrictions and directives have entered the construction industry. Photovoltaic is asustainable, clean and quiet solution that integrates well in the urban environment buthave not yet reached a breakthrough on the Swedish market. The conditions for solarenergy production are often set in the early planning stages where they rarely arebeing prioritized.This master of engineering project focuses on identifying problems regardingimplementation of photovoltaic in city development projects and giving suggestions topossible improvements in the planning- and construction process. It also givesrecommendations on how the conditions for energy production can be optimized inthe early zoning stage.By conducting simulations with PVsystV5.21, on three ongoing city developmentprojects in Umeå, Malmö and Stockholm and by carry out and analyzing interviewswith city planners, constructors and architects, some conclusions have been made.Several improvements, both politically, with changes in the subsidization systemand/or instatement of a new law with feed-in tariffs, and within the solar- andconstruction industry itself, with better communication between different parts of theprocess as well as better use of experience, can be made.

The construction and real estate industry represents a significant part of Sweden's total impact on the environment and mainly affects the following national environmental objectives: reduced climate impact, a good built environment and a non-toxic environment. By establishing internal rules, companies within the industry can reduce their environmental impact. SMT (AB Sandvik Materials Technology), a part of the industrial group Sandvik AB, has set a target that during 2014 develop a guiding document with special consider to the environmental impact during construction of office buildings, that they establish at the Swedish regional capital Sandviken, for both internal and external tenants. This study therefore aims to clarify which environmental aspects that the construction and real estate sector mainly are responsible for, and therefore should be part of a guiding document for a company for establishing office buildings, and to present arguments regarding the use of such a document. The study is based on literature studies and personal contact with other companies, in the form of e-mail conversations and a telephone interview.

As revenues from newspaper advertising plummet and their readers loyalty erode, the need to understand newspapers' changing environment and the actors involved in this change is growing in importance. Evidence is the entire industry is entering into a restructuring phase and that this restructuring is driven by the rapid consumer adaption of internet media.In this thesis I elaborate on "how the Internet is affecting the conditions for value creation in printed newspapers" and "how the Internet is affecting the conditions for other actors involved in the printed newspaper's value creation". These two questions land us in the bigger question of "Does the Internet act as a compliment or a substitute to the printed newspaper ".To answer these questions the printed newspaper is represented as the actor in the middle of content producers, advertisers and consumers. It is in its role as a means of distribution and as a co-ordinating force that we study the value creation of the printed newspaper. The empirical base of this thesis is a qualitative participant observation where the author during a period of time interacted and collected data from the open discussion in blogs by several of the industry's top influentials combined with material from seminars and reports on the current state of media.

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.
