Just food transition in Finland : developing transformative capacity of beef & dairy farmers to adopt climate-smart peatland management
(2026)A plant-based dietary transition is required to reduce the climate impact of the current agrifood regime characterised by high production and consumption of livestock-based products. In Finland the plant-based dietary ... -
Techno-economic and operational assessment of a solar-assisted hybrid liquid air energy storage under off-design conditions
(2026)This thesis aims to develop an hourly full-year simulation of a solar-assisted hybrid LAES system and compare it with a standalone base under Finnish operating conditions. The hybrid model couples a LAES core plant which ... -
Renewable integration strategies for data centers : opportunities and challenges for efficiency and scalability
(2026)The thesis investigates the way in which renewable energy, battery storage, UPS operation, and flexible IT workloads can be combined in a grid-connected data center to reduce the grid electricity consumption and to use ... -
Integration of OpenFAST-derived boundary conditions into ANSYS APDL for high-fidelity stress analysis based on 3D finite element models
(2026)Wind turbine blades are still maintained using preventive schedules that rely on theoretical load spectra. In practice, however, the actual loads during operation cannot be measured, and the conditions at each site differ ... -
Electric motor stator core fixing improvement based on strength analysis
(2026)This thesis investigates welding and needed amount of welding for a stator core used in an axial-flux electric motor of elevator. The objective was to reduce the amount of welding required in the stator core assembly while ... -
Evaluation of materials and welding processes for underground rainwater harvesting tanks in date centres

Evaluating the role of agentic digital twin in service lifecycle management : a comparison with real-time simulation-based systems
(2026)As industrial assets become more complex, maintenance systems must move beyond human-supervised operation. This thesis compares two digital twin paradigms in Service Lifecycle Management (SLM) namely Agentic Digital Twins ... -
Offset-free model predictive control for an active magnetic bearing system
(2026)Active magnetic bearing systems are challenging to control because the rotor is open-loop unstable, the magnetic force is nonlinear, and the coil currents are limited by the actuator hardware. Model predictive control is ... -
Flexible electric boilers as part of the energy system of the future
(2026)Decarbonising district heating through electrification is widely advocated, but its value within a carbon-neutral biomass combined heat and power (CHP) system is ambiguous. This thesis examines the cost and emissions effects ... -
Assessing energy justice in renewable energy scenarios for Sub-Sahara Africa
(2026)Transition to RE raises certain opportunities but also threats for the Sub-Saharan Africa (SSA) where enormous renewable energy potential coexists with energy poverty. The current thesis is intended to address the problem ... -
