A risk model with renewal shot-noise Cox process
(2019)
Catastrophic events may lead to sudden changes in the claim arrival rate and as a result it is difficult to predict the likelihood for the occurrence of these events. These random fluctuation cannot be modeled as a homogeneous ...
Entropiaan ja samankaltaisuuteen perustuva muuttujan valintamenetelmä markkinointiin liittyvässä luokitteluongelmassa
(2019)
Kandidaatintyössä tavoitteena on tutustua entropiaan ja samankaltaisuuteen perustuvaan muuttujan valintamenetelmään sekä samankaltaisuuteen perustuvaan luokittelumenetelmään. Muuttujan valinnan tavoitteena on rajata datasta ...
Deterministiset ja tilastolliset inversiomenetelmät röntgentomografiassa
(2019)
Kandidaatintyössä tutustutaan röntgentomografian inversio-ongelmaan ja sen ratkaisemiseen.
Työn toinen luku on teoriaosuus, jossa ensiksi johdetaan röntgentomografian matemaattinen malli, diskreetti Radon-muunnos. ...
Fysiikkasimulaatiot videopeleissä
(2017)
Työssä kartoitetaan saatavilla olevaa tietoa fysiikkamoottoreista, ja miten niitä käytetään videopeleissä. Aihe on rajattu mekaanisen liikkeen ja virtauksen simuloimiseen.
Fysiikkamoottori on videopelikontekstissa ...
Identification of customer profiles from electricity consumption data
(2018)
The electric power suppliers are interested in identifying and categorising their consumers’ profiles into different categories according to their energy consumption habits. The profiling of users can help with understanding ...
Constitutive modeling of hyperelastic fibrous material
(2018)
This thesis will concentrate on the deformation of bodies from incompressible and compressible materials. The analysis is based on several approaches, the first approach is an analytical way. Here we will plan to consider ...
Analysing electricity consumption data by fast search and find of density peaks
(2017)
The aim of this thesis is to compare a clustering method called Clustering by fast search and find of density peaks (CFSFDP) (Rodriguez et al. 2014) to two traditional clustering methods in analysis electricity consumption. ...
Unsupervised anomaly detection from wooden boards using autoencoders
(2019)
For wood processing in the sawmill industry, quality of the raw material in every step affects the production efficiency. Defects in the sawn timber, such as wane, knots, cracks, watermarks, fungal damage, insect defects, ...
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 ...
Moving Object Analysis and Trajectory Processing with Applications in Human-Computer Interaction and Chemical Processes
(Lappeenranta University of Technology, 2018-12-13)
In order to better understand processes with moving objects using computer vision, it is important to be able to measure and to analyze how the objects move. The recent advances in imaging technology and in image-based ...
