Artefakti pri PET/CT slikanju - pregled literature
Tomaž Sevšek, Luka Žnidarič, Sebastijan Rep, Janez Žibert
Diplomsko delo
Oznake: diplomska dela;radiološka tehnologija;PET/CT artefakti;artefakti zaradi kontrastnega sredstva;SCC algoritem;artefakti zaradi kovine;kovinski vsadki;iMAR;artefakti zaradi respiratornega gibanja;respiratorni gating;
Uvod: PET/CT slikanje je sodobna diagnostična metoda, kjer se poleg anatomskih informacij opazuje tudi fiziološko delovanje pacientovega telesa. Kontrastna sredstva, kovinski implantati ali respiratorno gibanje pri slikanju povzročijo značilne artefakte. Odpravljanje le-teh je ključnega pomena za zv ...

Predicting the deep drawing process of TRIP steel grades using multilayer perceptron artificial neural networks
Luka Sevšek, S. Vilkovský, J. Majerníková, Tomaž Pepelnjak
Izvirni znanstveni članek
Oznake: forming;deep drawing;TRIP steel;artificial neural network;finite element methods;modelling;simulation;
TRIP (Transformation Induced Plasticity) steels belong to the group of advanced high-strength steels. Their main advantage is their excellent strength combined with high ductility, which makes them ideal for deep drawing processes. The forming of TRIP steels in the deep drawing process enables the p ...

Influence of process parameters on the characteristics of additively manufactured parts made from advanced biopolymers
Tomaž Pepelnjak, Josip Stojšić, Luka Sevšek, Dejan Movrin, Mladomir Milutinović
Pregledni znanstveni članek
Oznake: aditivne tehnologije;biopolimeri;medicinske aplikacije;procesni parametri;kompleksnost delov;additive manufacturing;biopolymers;medical applications;process parameters;part complexity;
Over the past few decades, additive manufacturing (AM) has become a reliable tool for prototyping and low-volume production. In recent years, the market share of such products has increased rapidly as these manufacturing concepts allow for greater part complexity compared to conventional manufacturi ...

Determining the influence and correlation for parameters of flexible forming using the random forest method
Luka Sevšek, Sandi Baressi Šegota, Zlatan Car, Tomaž Pepelnjak
Izvirni znanstveni članek
Oznake: incremental sheet metal forming;multi-step sheet forming;finite element method;random forest method;parameter influence analysis;parameter correlation analysis;
Single-point incremental forming (SPIF) enables the forming of fix-clamped sheet metal by moving a relatively small geometrically simple tool along the trajectory, producing the desired shape of the final product. Excessive thinning of the sheet results in fracture, determining the limit of formabil ...
