1. Development of a High Current Charger for Small Electric Boat Commuting
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Electrification of the transport system is an important societal project which we are currentlyundergoing. With improvements in battery technology it is now possible to construct quite powerfulpersonal vehicles to replace combustion engines in not only cars but also motorcycles and boats. LÄS MER
2. Inversion of Markowitz Portfolio Optimization to Evaluate Risk
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This project investigates the applicability of the originalversion of Markowitz’s mean-variance model for portfoliooptimization to real-world modern actively managed portfolios.The method measures the mean-variance model’s capability toaccurately capture the riskiness of given portfolios, by invertingthe mathematical formulation of the model.

3. Modelling and Simulation of a Propulsive Hybridisation for a Light Fixed-wing Aircraft
Master-uppsats, KTH/FlygdynamikSammanfattning : Propulsive hybridisation fits in with the sustainable development policies of many companies which are part of the transportation industry. Actually, it makes it possible either to reduce fuel consumption or to improve the aircraft performance at a fixed fuel burn. LÄS MER
4. Shifting the sun : Can coupling Lithium-ion batteries with solar power be economically justified in a Dutch setting?
Master-uppsats, KTH/EnergiteknikSammanfattning : The rapid development of the lithium-ion battery industry is currently driving down sys-tem costs as a result of maturing processes. Decreasing system costs enables additional revenue streams and applications, provided through li-ion battery storage, to be ex-plored. LÄS MER
5. Utveckling av lingående sond för mätning av ljudhastighetsprofil i hav
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Det är viktigt att veta ljudhastigheten på olika djup i vatten vid sonarsökning efter gömda föremål på havsbotten. Rapporten behandlar olika tänkbara sätt att få en sond med en ljudmätare att klättra längs en lina i vatten mellan en towfish med sonarutrustning och ett bogserfartyg på ytan. LÄS MER
