Leder storskaliga landinvesteringar i jordbruk till hållbar utveckling? En fallstudie av projektet ProSavana i Moçambique

Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.

Möjliga tillämpningar av BIM vid miljöcertifieringsarbete

In the construction industry today there is a significant technological revolution goingon. New methods for automated processes and information management are developedcontinuously. Intense studies are currently taking place to ensure ways and means toembrace the new technology of BIM.At the present, environmental certification systems are considered cumbersome andchallenging. However, the increasing demands of sustainable development in the constructionindustry imply that the environmental certifications will not disappear. ThisMaster Thesis examines the possibilities to apply BIM technology within the field ofenvironmental certifications to streamline the processes.The applications that provide the best opportunities are:- To use BIM to be able to, during the design stage, dynamically evaluate the resultor score a certain building will achieve.- To avoid unnecessary work through collection of data for calculations directlyfrom a BIM-model.- To be able to automate certain time consuming calculations that are currentlyperformed manually.- To automatically examine the completed model to ensure that the demands arefulfilled.The possibilities to use BIM within these areas are however limited by the technologyitself.

Poetry Slam. En studie av vilken betydelse Poetry Slam har som litteratur och som identitetsskapande verksamhet för ett antal tävlingsdeltagare.

Today, the definition of literature has changed. Walter J. Ong talks about the secondary spoken language that has surfaced as a result of new technical innovations to our writing tools. This also transforms our attitude towards literature and we can see a return to literature based on verbal characteristics. According to Hans Hertel the verbal renaissance reflects a modern man need to come closer to each other and create togetherness.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Blir det bättre med tiden? : En studie av Large cap-noterade bolags nedskrivningsprövningar av goodwill

År 2005 beslutades att svenska företag vars aktier är noterade på en reglerad marknadsplats ska upprätta sina årsredovisningar enligt regelverket IFRS. En av många förändringar som detta medförde var att den immateriella illgången goodwill årligen ska nedskrivningsprövas, istället för att som tidigare linjärt avskrivas. För att utföra en nedskrivningsprövning måste ett företag värdera goodwill. Det inbegriper att fastställa en rad antaganden och precisera nyckeltal. Information om processen ska enligt standarden IAS 36 finnas att tillgå i företagets årsredovisning.

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

The work is performed at Forsmark Group AB as a final step in the Bachelor ofScience program in nuclear engineering at the University of Uppsala in 2013.The work is part of an ongoing process of streamlining project system model FKA.Streamlining the project model is an important aspect that affects all largecompanies that somehow have a project governing body when there is muchfinancial resources to save. Although the quality of the projects is positivelyaffected by efficiencyThe aim is to find possible common weaknesses and strengths of the project systemby interviewing a number of project managers, and using the systems in placeexamine the model.As part of the work also includes examining what project managers have to adjust tothe newly implemented system VPMM, and other newly introduced elements thathave been added to improve the efficiency in the futureProject System is a complex system that is influenced by many different parametersand participating individuals' attitude and personality. But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..

Professionell färdighetsutveckling på ett civilingenjörsprogram : en utvärdering av kompetenser hos alumner

The Master of Science in Energy Systems Engineering program at Uppsala University started in 2000 and 221 students has graduated since. This master thesis aims to answer what competencies alumni considers most important for successful professional practice. It also seeks to find out how these competencies are reflected in the program to identify potential gaps between importance and how the competencies are being prepared. With inspiration from similar research a method has been developed consisting of two steps: (1) A survey and (2) interviews with alumni. The alumni survey rates the professional importance of 13 competencies and how well the corresponding competency is prepared in the program.

Vidareutveckling och utvärdering av operatörsplatser på svenska stridsfartyg

The ability to handle potentially dangerous and hostile situations on a military vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.

Analys och kvantifiering av energieffektivisering inom fjärrvärmesektorn

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects district heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for district heating customers to invest in energy efficiency measures.Result of the Excel model shows that the district heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.

Elektronisk motorstyrning för ottomotorer

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Design och implementation av konfigurationsverktyg för funktionsblock

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

Distribution av känslig data

Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.
