Alternativ till fortsatt elektrisk generering i Olidan
In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.
Health added-value food : the Swedish retail market
Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods.
The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.
Validering av Casmo-5M / Simulate-3
The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).
Återanvändning - Sättet att ge hemelektronik ett andra liv
Increased consciousness about environmental and sustainable issues has led to consumers and companies who are more in favor of reuse and recycle. Even though this is a fact, people today are buying new things more often compared to before. For instance for a mobile phone the functionality lifecycle is eight years which can be related to the economic lifecycle today which is 1.5 years compared to 3 years in 1995. Only 1-2 percent of the mobile phones thrown away in Sweden today are handed in for recycling. The purpose of this study is to investigate whether an international company within the recycling and reuse of mobile phone industry has a market in Sweden.

Risker vid svensk företagsverksamhet i Estland
All companies face risk in their daily business. Internationalised companies tend to experience higher risk due to for example unfamiliar business environment than companies that act only on the national market. Estonia became independent as late as in 1991 and is therefore a new interesting market for many companies in neighbouring countries like Sweden. Risks that are most apparent for an internationalised company are political risk, currency risk, capital and interest rate risk, business risk and credit risk. Our intention of this study was to find out how Swedish companies acting on the Estonian market faced the different risks when entering the Estonian market and how they value the risks today.

Att mötas på webben : Hur sociala medier påverkar B2B relationen
The purpose of this study is to investigate how social media can affect and influence the B2B-relationship. Social media is now a widespread and accepted tool for communication in many B2C-companies; therefore we find it interesting to examine how social media can find its place in the communication mix of B2B-companies. We are also aiming to distinguish standards in how social media is practiced and discussed in the context of the B2B-market. We have applied a qualitative method for this study and we have interviewed seven respondents, which are experts in social media or working with market communication at B2B-companies in Sweden. During our study we have identified several comparable attributes within the B2B market and their opinions about how social media should be approach and adopt in the communication mix of the company..
Om du säger det så
This study explores the different effects on attitude and behaviour three frequently used advertising techniques have. The techniques compared are social influence and egoistic and altruistic benefit-appeals. The results showed that ads featuring social influence had statistically significant higher mean values regarding attitude towards the ad compared to both the other ads, and significantly higher mean values regarding brand attitude compared to the ad appealing to egoistic motivations. Though, all advertising effectiveness measures used in this study - that is, attitude and intention variables - indicated that social influence was more effective than the other advertising messages. Thus, in accord with earlier studies, it can be stated with confidence that social influence is an effective tool to use in marketing communications..
Aktiefonder : Ett lönsamt investeringsalternativ?

Method: We had started out from the qualitative method theory which is based on
the hermeneutic theory, because we will interpret and understand. With this
starting point we have chosen to use a case study with semi-standardised
interviews supplemented with information from different documents, and to get
the theoretic connection we have studied literature in the subject field. The
analyse and even the theoretic connection have then started from, for this
study, a special analyse model.
Results: Througt systematic and target-concentrated management and through
cooperated factors, with stress on a leadership that is both professional,
visionary and un-combined, and there the staff´s is seen as a important
resource, and there it is a clear strategy and objective to keep the cost of
the activity within assigned budgetframe, has a public field of action, as the
clinic of hab./rehab.
Psykiska avståndets påverkan på internationell handel
The global market is becoming increasingly integrated and to keep up with growing competition and to achieve even greater success, companies expand to foreign markets. Previous studies have shown that the concept of psychic distance has an important impact on international performance regarding small and medium-sized enterprises (SME). The aim of our study is to provide the reader with a deeper understanding of how psychic distance influences export performance regarding Swedish SMEs. Through a single case study of a Swedish SME, we chose to research three different markets in three different continents. Our findings show that psychic distance influences export performance through export marketing strategy and active learning.
