Utvärdering av VAV i nybyggt kontorshus

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Möjligheter att öka effektiviteten och det ekonomiska utfallet av barkhanteringen vid Seskarö sågverk :

The sludgebark and to a certain extent the bark were until a decade ago waste products without any economic value that were thrown away. A number of environmental laws and increcing energy prices have improved the prerequisites for increasing the use of these materials. At Seskarö sawmill they burn the sludgebark and a great deal of the bark in the sawmill furnace. The sludgebark has a number of disadvantages compared to bark during burning. The sludgebark is often wet which means the energy net from burning often gets low.

Bevarande av dagstidningar i Sverige en probleminventering

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.

Personuppgifteshantering och identifiering inom myndighet, skola och förtag

The authors of this thesis have studied the handling of personal information in various kinds of organizations, because the perception is that the knowledge in this area is weak relative to the weight of the subject.The purpose of this paper has been partly to shed light on how knowledge of this area in the organizations that we have visited during the study but also to answer questions about handling, knowledge and security, and identification of individuals in different systems. What kind of problems the processing of these data creates and why these problems occur.In the beginning of our study we understood the importance of using the correct identifier and therefore chose also to examine what the various identifiers used by the organizations and why they chose these particular identifiers.In the qualitative analysis, Datainspektionen´s general rules and advice has been used as a basis together with the laws applicable to the organizations to get a good picture of how management of personal information is in these organizations.What we have found in this paper is that knowledge about how personal data is handled and what laws and rules are saying is very much dependent on how central the information is to these organization's activities. The police use so many different types of records for their organization to function well and they have very good knowledge of laws and regulations. In contrast, schools that do not handle as much of personal data themselves nor have the same knowledge among staff and do not have enough resources to cope with keeping the same knowledge base as the police. This is something that applies to all types of handling, depending on how important the information is for the organization, the better the security and knowledge in handling the data is..

Biogasrötning av socker- och foderbetor : Jämförelse av färska, stuklagrade samt ensilerade betor i laboratorieskala

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

Undersökning av solcellspotentialen för golfverksamheter i Sverige

Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.

Referenser i informationsåtervinning: utvärdering av en sökstrategi för citationsindex

In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.

Elevers litterära föreställningsvärldar

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

I denna studie har vi utvecklat, testat och utvärderat ett uppföljnings-instrument som följer upp personalens användning av och uppfattning om informationssystemen i en socialförvaltning. Uppföljningsinstrumentet är utformat utifrån en redan etablerad modell (Information Systems Success Model). Inhämtningsdelen har vi utformat i form av en enkät. Analys och redovisningsdelen har vi utformat utifrån modellen. Uppföljningsinstrumentet kan användas som en del i en socialförvaltnings kontinuerliga förbättringsarbete och kräver inga förkunskaper i informatik eller informationslogistik för att användas..

Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

Tillämpad informationsteknologi i klassrummet

This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.

Jordbruk och mjölkproduktion med kor i Etiopien :

Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.

Public Welfare vs Return on Shareholders´Equity -A Case Study of the Translation & Implementation of the Management Control Systems in Systembolaget

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target.
