Energi- och exergiflöden i stålframställningsprocesser vid
SSAB Tunnplåt AB i Luleå

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

Märken i morgonljuset En kvantitativ studie av varumärkesexponeringen i Tv4:s Nyhetsmorgon

AbstractAuthors: Agnes Källén & Amanda RedinTitle:Level: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of Pages: 39With this study we aimed to answer the following questions: has the amount of brand exposure on the Tv4 show ?Nyhetsmorgon? increased between the years 2008 and 2013? And if so, how can the increase be explained by well-recognized research in the field?The media industry is changing toward an increasingly commercial content. In television, this change is mainly caused by the growth in shows watched on the web and through time shift, which is the act of watching something on a digital video recorder, or DVR. This gives the viewer the possibility to fast forward through the commercial breaks, and therefore forces the networks as well as the advertizer to find new ways to reach consumers. Hence the plausible growth in product placement and brand exposure.

Transportlogistik : vad påverkar åkeriföretagens konkurrenskraft på en tillväxtmarknad.

All inclusive travel has become a popular way to travel abroad. When tourists pay for everything in advance their need for contact with the local people will be reduced. The consequences of this can be dissatisfaction from the local people as they are left out and do not share the financial benefits created by tourism. During the purchasing cycle of an all inclusive travel, it is possible that the tour operator can influence a sustainable development.The aim of this paper is to compare how a large and a small tour operator in their purchase of all inclusive holidays interacts with local players to create sustainable development, thereby creating a surplus value to the customer. The hypothesis is that the amount of knowledge and application of this knowledge regarding sustainable development differs in the purchase process between large and small tour operators.This paper was carried out as a case study.

Optimering av driftläggningar i Fortums nät

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Hur kan kostnaden minskas för dörrmiljöer utan att försumma funktionen?

The door and its surrounding, is an important part of all buildings. It often amount to a significant part of buildings total costs. The more demands of functions the largerdoes the costs grow.The purpose of this report is to analyze those demands and how to fulfill them.Another purpose is to examine of which reasons the cost grow and how to avoid it inthe best possible way. The study will be performed in collaboration with Bjerking AB. To define the demands a literature study will also be performed.

Drivaxeltrycksreglering hos tunga fordon : För en ökad framkomlighet vid vinterförhållanden

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

Genomförandet av bemanningsdirektivet 2008/104/EG : En problematisk implementering för Sverige?

AbstractThe use of temporary agency workers has increased significantly during the last decades. Due to considerable differences in the legal status and working conditions of temporary agency workers within the EU, the directive 2008/104/EC on temporary agency work was adopted in 2008. The current directive has a two folded purpose, first and foremost to improve the employment and working conditions for temporary agency workers, by establishing the principle of equal treatment. The second purpose is to create greater acceptance for the temporary work agencies, and also to review and remove any unjustified restrictions or prohibitions against them.There are several different models for labour market regulation represented within the EU. The Swedish and Nordic model has through history relied heavily on regulation via collective agreements, entered into by the social partners, with a minimal amount of state interference and regulation.For Sweden there is a potential problem in the implementation of the directive on temporary agency work, since it follows from case law by the European Court of Justice (ECJ).

Handikappad eller frisk? : - två tidskrifters perspektiv på idrott

AbstractPurpose/Aim: The aim is to investigate if there are any differences in the reporting from the Olympic games and the Paralympic games, according to different periodicals or magazines, with focus on Paralymics and sports for handicapped. If so, what are those differences?Material/Method: The material consists of two periodicals, or magazines; Svensk idrott which is the official paper for the swedish Riksidrottsförbundet, and Handikappidrott, which is the official paper for the swedish Handikappidrottsförbundet. Articles considering the summer games in 1972 and 1976, 1984, 1996 and 2000 was studied with regard to models developed by Algirdas J. Greimas.

Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia

The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.

Utvärdering av solcellsanläggningen på Universeum

The main aim of this master thesis was to see the process of an interactive online reference service from idea to final product. The reference service we have studied is developed and used by the Library of the National Institute for Working Life in Stockholm, Sweden and goes by the name phibi. Our goal was to review the whole realization process from the reasons why a service like this was created, how the service was introduced and implemented inside the organisation and finally what the result and consequences were for both the library staff and for the users of the service. Phibi is designed to be a tool that fosters communication between the library staff and the remote users where the users get the opportunity to be helped with their questions by the library staff although they are not physically present in the library. To understand the process we conducted a case study with 11 interviews of the library staff, the superior and the initiator to phibi.

Klagomålshantering i den svenska bankbranschen

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Äldre invandrare och den offentliga äldreomsorgen - bistånd, behov och särskildhet

The purpose of this study is to investigate whether an increasing amount of elderly immigrants will set new demands upon the public eldercare. The focus is on the officials whithin the public care of elderly in Västra Götaland district, and their experiences. A second purpose of this study is to add the experiences of the officials to former research treating the topic of elderly immigrants and their experiences of the public eldercare in Sweden.The survey has been carried out through interviewing all together seven officials working within the public care of elder in varying districts of Västra Götaland. The interviews have later been summoned under four different themes such as, ?Culture, customs and tradition?, ?Interaction and communication?, ?Information? and ?The future of the public eldercare?.The study indicates that our result based on the interviews, is in several references corresponding to former research on the topic.

Det Intelligenta Huset : - En studie i hemautomation

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Aquaculture : animal welfare, the environment, and ethical implications

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.

Konstruktion av instrument för dragprov på nervceller

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
