CFD-based optimization for wind turbine locations in a wind park
(Lappeenranta-Lahti University of Technology LUT, 2019-05-10)
Searching for the optimal positions of wind turbines in a wind farm for their maximal power generation has an important and difficult role in the wind energy industry. Several factors have to be considered while designing ...
The linguistic approximation of fuzzy models outputs
(Lappeenranta-Lahti University of Technology LUT, 2019-11-29)
Linguistic approximation is a process of assigning linguistic labels to various mathematical objects, frequently ones that are obtained as outputs of fuzzy models. Such an assignment cannot be arbitrary – the usual requirement ...
Advanced Techniques for Unsupervised Classification of Remote Sensing Hyperspectral Images
(Lappeenranta-Lahti University of Technology LUT, 2019-05-20)
Hyperspectral images consisting of a broad range of contiguous spectral bands ought to be a valuable tool for land cover type mapping. However, the coarse spatial resolutions of remote sensing Hyperspectral images makes a ...
Ni-Mn-Ga magnetic shape memory alloy for precise high-speed actuation in micro-magneto-mechanical-systems
(Lappeenranta University of Technology, 2019-01-17)
Single crystalline Ni-Mn-Ga alloys are known for their large reversible magnetic-field-induced strain (MFIS) of several percent. This effect was discovered and named magnetic shape memory (MSM) by K. Ullakko in 1996. Since ...
Heuristic similarity- and distance-based supervised feature selection methods
(Lappeenranta-Lahti University of Technology LUT, 2019-12-16)
In the field of machine learning, the available data often contain many features to describe phenomena. This can pose a problem since only those features that are relevant to characterize the target concept are needed, ...
