Coolability of porous core debris beds : Effects of bed geometry and multi-dimensional flooding
(VTT Technical Research Centre of Finland Ltd, 2015-10-23)
This thesis addresses the coolability of porous debris beds in the context of severe
accident management of nuclear power reactors. In a hypothetical severe accident
at a Nordic-type boiling water reactor, the lower ...
Adaptive Markov chain Monte Carlo and Bayesian filtering for state space models
(Lappeenranta University of Technology, 2014-12-12)
This thesis is concerned with the state and parameter estimation in state space models. The estimation of states and parameters is an important task when mathematical modeling is applied to many different application areas ...
Heterogeneous mass transfer in fluidized beds by computational fluid dynamics
(Lappeenranta University of Technology, 2014-12-02)
The main objective of this research is to estimate and characterize heterogeneous mass
transfer coefficients in bench- and pilot-scale fluidized bed processes by the means of
computational fluid dynamics (CFD). A further ...
Integrated hub gear motor for heavy-duty off-road working machines - interdisciplinary design
(Lappeenranta University of Technology, 2017-03-23)
This doctoral dissertation studies solutions that meet the demands made for the propulsion
motors of off-road working machines. It has been shown that in a hybridization process,
without a mechanical gear, it is not ...
Training system for conceptual design and evaluation for wastewater treatment
(Lappeenranta University of Technology, 2010-12-17)
Rising population, rapid urbanisation and growing industrialisation have severely stressed water quality and its availability in Malawi. In addition, financial and institutional problems and the expanding agro industry ...
Impacts of capacity remunerative mechanisms on cross-border trade
(Lappeenranta University of Technology, 2015-09-21)
The European ambitious targets to increase the share of renewable generation pose a challenge
to the generation adequacy. Many European member states are concerned that energy-only
markets alone might not be able to ...
Innovation in a Non-Formal Adult Education Organisation – Multi-Case Study in Four Adult Education Centres
(Lappeenranta University of Technology, 2013-06-14)
More than ever, education organisations are experiencing the need to develop new
services and processes to satisfy expanding and changing customer needs and to adapt to
the environmental changes and continually tightening ...
Mathematical modeling and optimal control of malaria
(Lappeenranta University of Technology, 2014-12-16)
Malaria continues to infect millions and kill hundreds of thousands of people worldwide each year, despite over a century of research and attempts to control and eliminate this infectious disease. Challenges such as the ...
Identifying the influence of an operational environment on environmental impacts of waste management
(Lappeenranta-Lahti University of Technology LUT, 2019-12-13)
Ever-increasing waste generation, resource depletion and awareness of adverse environmental impacts all factor into the growing application of life cycle assessment (LCA) as a method for evaluating the potential environmental ...
Enabling constructive alignment in programming instruction
(Lappeenranta University of Technology, 2011-06-10)
In this thesis, simple methods have been sought to lower the teacher’s threshold to start to apply constructive alignment in instruction. From the phases of the instructional process, aspects that can be improved with ...
