Electrification and digital tools are both on the rise. Digital tools can save time and resources, while for example hybrid and full electric marine vessels decrease operating costs and emissions in transport. These vessels require their power electronic devices to work...

Tässä kandityössä tutkitaan polymeerikomposiittien käyttökohteita ja käyttöön johtaneita syitä veneteollisuudessa. Työssä on selvitetty veneteollisuuden erityisiä materiaaleihin liittyviä vaatimuksia, sekä polymeerikomposiittien soveltuvuutta veneteollisuuteen. Työstä s...

Tämän diplomityön tarkoituksena on määrittää teknologiset vaihtoehdot lämpöenergian talteenotolle, varastoinnille ja hyödyntämiselle Itämeren alueen avustavalle jäänmurtajalle. Lämpöenergian talteenoton ja varastoinnin tarkoituksena on alentaa polttoaineen kulutusta, pä...

In this master’s thesis, I propose a best practice for providing reduced 3D models to marine customers at sales stage at ABB, a company designing and manufacturing large electric machines. Marine customers often request 3D models early in the sales process to integrate ...

Follikulaarinen kystiitti on koirilla harvinainen virtsarakon muutos, joka on kuvailtu aikaisemmin kirjallisuudessa puuttellisesti. Tapauskertomuksia follikulaarisesta kystiitistä koirilla on vain kaksi, joista toinen on kirjoitettu 1940 ja toinen vuonna 2014. Tutkielma...

This master’s thesis is a research for identifying means to improve the manufacturability of marine feeder-booster fuel supply units. The client company Auramarine Ltd. desires to improve the manufacturability of their products for better competitiveness and relieving t...

Enhanced release of alkalinity from the seafloor, principally driven by anaerobic degradation of organic matter under low-oxygen conditions and associated secondary redox reactions, can increase the carbon dioxide (CO2) buffering capacity of seawater and therefore ocean...

Abstract Background Clupeid fisheries in Lake Tanganyika (East Africa) provide food for millions of people in one of the world’s poorest regions. Due to climate change and overfishing, the clupeid stocks of Lake Tanganyika are declining. We investigate the population st...

The pivotal target of the Paris Agreement is to keep temperature rise well below 2 °C above the pre-industrial level and pursue efforts to limit temperature rise to 1.5 °C. In order to meet this target, all energy consuming sectors including the transport sector need to...

The pioneering work done during the past three decades in the regulated Rivers Perhonjoki and Kalajoki, Finland, to study and rehabilitate river lamprey populations is presented. The effects of various anthropogenic activities and rehabilitation measures are evaluated b...
