Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Termisk Vattenpump
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.
Managementrapport
Denna rapport är skriven inom ramen för magisterkursen Management och på uppdrag av HSB Malmö. Rapporten är indelad i tre delar där den första utgör huvuddelen och syftar till att spegla vårt projektarbete på HSB Malmö. I denna delen beskrivs och tolkas HSB Malmö i nuläget, samt presenteras rekommendationer till hur ledningen i framtiden bättre ska kunna skapa organisatoriska förutsättningar för ett strategiskt förändringsarbete. Utifrån vårt syfte och den information som vi samlat in, har vi valt ut ett antal teman som vi anser är mest intressanta och utmanande för HSB Malmö att jobba med i önskan om att nå större framgång i strategiskt förändringsarbete. Dessa teman (medlemsorganisation eller vinstdrivande företag?, kundorientering, kommunikation och information, kompetens, visionsarbete, ledarskap, företagskultur och organisationsstruktur) utgör grunden för den diagnos av situationen på HSB Malmö som vi presenterar i rapporten.
Ambidexterity genom organisatoriska IT-förmågor
Det har länge påvisats fördelar med innovation och effektivisering av verksamheter. Med konceptetambidexterity har ett senare forskningsparadigm försökt förklara hur organisationer lyckas uppnåbåde innovation och effektivisering samtidigt genom att balansera strategiska initiativ.Denna litteraturstudie ämnar att visa vad existerande forskning ger för svar på hur organisationerkan uppnå ambidexterity ur ett IT-management perspektiv. Genom att kombinera litteratur omambidexterity med litteratur om IT-förmågor (IT-baserade organisationsförmågor för att möjliggörastrategi och initiativ) ger denna studie en bild av vad existerande litteratur kan ge svar på och vadsom saknas.Studien påvisar många likheter mellan de förutsättningar som beskrivs för att uppnå ambidexterityoch IT-management som organisationsförmåga. Däremot existerar en avsaknad av djupareförklaringar vad gäller de komponenter som IT-management som organisationsförmåga innefattar..
Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet
There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes.
District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption
Research), which has focused on climate adaption in the Nordic countries.
Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB
The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Intranät och dokumenthantering vid ett mindre till medelstort företag En fallstudie
The aim of this masters thesis is to learn how an organization has solved its information management via intranet and document management. The purpose is to identify what different types of information are made available via an intranet, how this information is structured and what functions the intranet includes. Conventions, directions and advice about intranets and document management were studied, with the purpose to compare whether the systems of the company correlate with these. Other issues considered in the thesis, are how the employees of the organization use the intranet and how the document management is organized. To get an understanding of these questions the structure and functions of the intranet were studied empirically and a questionnaire on what the employees need and use, concerning the intranet, was sent out to 130 employees.
Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö
In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely.
The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished
the result is graded in the following categories: economy, environment and quality.
To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.
Implementation of renewable energy in the Republic of Moldova : society and landscape in transition
The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing
a phase of transition in both society and landscape. They have hardly any fossil depots and
are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected
government wants to move towards the EU and this is generally seen as the way to grow and reduce
poverty. Security in the energy sector is important and one tool is to increase the use of renewable
energy sources.
Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in
Moldova through a society development perspective. The study has aimed to investigate the sociotechnical
complexity of this subject and to discuss the potentials and way of dealing with the subject in
the specific cultural context of Moldova.
Solenergi i Norrra Djurgårdsstaden
This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Ledningsarbetet hos ett krisföretag : en analys av ledningens hantering av en ekonomisk kris
Almost every company sooner or later ends up in a more or less difficult economical situation. The reason for the economical crisis varies for each individual case but common for them all is that it is the management group that has failed in their work to guide the organisation to avoid a negative result. The next common denominator is that it is the management group that has to handle the changes in the company's environment and lead the company out of the crisis. But how can they do this and take decisions in a rational and effective way and is there warnings signals that the management group missed before the crisis was a fact? This is
some of the questions that this study is going to discuss and analyze.
The aim of the study is from a management perspective chart the strategic work of the company's management work when handling an economical crisis.
