Bioethanol is one alternative energy fuel that can be produced from different types of biomass. Second generation bioethanol comes from fermentation of lignocellulosic material and can be seen as a more environmental friendly alternative as e.g. forest residues and agricultural by-products are used. To be able to use lignocellulosic biomass in ethanol production, it has to be subjected to different treatments first. In this study, aspen sawdust was used as lignocellulosic material.

Extreme Production Makeover? fångade vårt intresse för en tid sedan, strax innan vi skulle börja skriva vår C-uppsats. Metoden går ut på att under mycket kort tid förändra och effektivisera en produktionslina för att höja produktiviteten. Vi blev genast nyfikna på om Extreme Production Makeover? skulle gå att omsätta i administrativa flöden och tjänste-flöden med ett informationslogistiskt perspektiv.Inom produktion finns det en lång tradition av att arbeta med effektiviseringar och förbättringar.

Forskning har visat att barn som uppvisar ett normbrytande beteende i kombination med brister i empati och förståelse för ömsesidighet med andra har svårare för att bedöma rädda ansikten än andra barn med normbrytande beteenden. I en studie kopplades detta till att de inte läser av ögonen utan fokuserar mer på munnen. Föreliggande studies huvudsyfte var dels att validera ett instrument för mätning av barns ögonrörelser och relatera ögonrörelser till tolkning av känslor i ansiktsuttryck, dels att undersöka om barns empati generellt kan kopplas till skillnader i ögonrörelsemönster vid bedömning av ansiktsuttryck. En normalpopulation på 39 barn i 10-11 årsåldern bedömde ansiktsuttryck (glad, neutral, ledsen, arg och rädd). Föräldraskattningar av kognitiv och affektiv empati relaterades till deras förmåga att identifiera ansikten korrekt.

A real option model is developed to examine the crucial factors affecting the agricultural firms? decision to quit the production and rent out the land to a company building a PV power plant. The public policies in support of investments in renewable energies have created the conditions for a market regarding investments in PV installations in agricultural areas.The decision to switch offers to the agricultural firm and to society several economical, social and environmental benefits, representing sustainability. However, PV installations in agricultural areas require the allocation of a certain land area. By assigning a part of land to PV installations, thereby the area of land allocated to agricultural production decreases.

This essay discusses the issue of the role of women and also whether they could obtain a strong social position during the Viking Age. Moreover, it does discuss the question of how frequent women were present in Viking Age scriptures, art and archaeological artefacts in comparison to our view of women and her position in the modern society. The archaeological material used is in majority that found in Birka, such as burial and habitational findings. These objects, as well as other comparable and similar findings from other places, when put together with written sources, show that women had different roles in the society. She was able to have a strong social role during the Viking Age not only becauseof the status her family had but also because of her own merit depending of her skills and ability.The archaeological findings found in female graves and other findings in the area, suggest a specializing within both textile production and trade for the women.

In this paper we have theoretically built a house designed for people with impaired mobility. Theessay begins with an introduction in which the purpose of the work, the methodology and thedepth-research part is presented. Then the layout that explains how we intend to adapt the housefor the demands detailed in the depth-research part is presented. In the same chapter variousstructural components, such as different floors and walls, are specified.In the selection of materials we have taken into account the criteria of our specialization andadaptation to the aesthetic aspects, where we evaluate materials based upon our wishes regardingtechnique and form. There are also other aspects that are important in the selection of materials,including that these are adapted to technical traits of the construction elements and installations.In a later chapter the technical installations such as ventilation systems, heating systems,electricity and sanitation are presented, where both technical and financial aspects are describedin detail.

This thesis has had its focus on ceramic shards found in a trench by the late neolithic western shore of the Ajvide site. The purpose of the thesis is to investigate if there are changes in the pottery between the test trench and the ceramics found by the graves, known as the main site. The author has compared the ornaments from the test trench with an ornament schedule made from over 50 000 shards from the assumed main site. Not only changes regarding ornaments has been noticed but also new techniques and raw material. The author has also implemented two 14C datings which backs his hypothesis that the shards from the test trench are younger than the shards that made the earlier ornament schedule.

Is the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them.

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Zakrisdal and the west coast region of Karlstad was at one time a protected area where the ammunition factory AmF Zakrisdal 1941-1994 was situated. This factory manufactured explosives for the Swedish armed forces and for export. In this context it is an interesting paradox that the production of ammunition, mines and armorpiercing grenades for more than 50 years has preserved the environment surrounding the factory.The factory is now gone and the production is moved to Karlskoga. Plans are being made to build housing for 3-4000 residents and other enterprises within the area. The area now stands before yet another change, most likely the most profound to date.The inspiration for this work comes from the economic historic Jan Jörnmark.

This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.

This study is preformed at Westbaltic Components placed in Töcksfors Sweden. Themain target in this study is to make one of the company?s assembly lines better andmore effective. The assembly line constructs vending machines for different stores allover Europe.It will contain tobacco, snuff, cigarettes and shaving blades and many more similarproducts.The first step in our study is to locate the daily problems and find out a good way toreduce them and make them disappear. A good way to do this job easier was toconstruct a visualizing board.

Auditors have a big role in society. The question of auditor independence has been debated frequently after the financial crisis. Long auditor tenure with clients has both advantages and disadvantages so the question is hard to solve.One of the traits that are encouraged with auditors is professional skepticism. An important part of professional skepticism is the personal skepticism of the auditor. The purpose of this dissertation is to investigate if a high professional skepticism can increase auditor independence by increasing profession identification and decreasing client identification.
