1. Rakojević, Bojan B., 1980-. Efekti brzine izvođenja i širine mete na ostvarenu preciznost šuta u fudbalu.

Udarac po lopti prednjim dijelom stopala predstavlja jedan od najzastupljenijih tehničkih elemenata u fudbalu, i sa aspekta ispoljavanja brzine i preciznosti šutnute lopte predstavlja jedan od najefikasnijh udaraca u fudbalu. U naučnoj literaturi, izvođenje ovog udarca naziva se instep udarac što je opšte prihvaćen termin pod kojim se podrazumijeva izvođenje ovog tehničkog elementa. Analizirajući adekvatnu literaturu postavljeni su temelji istraživanja, koji su se u određenoj mjeri naslanjali na rezultate dosadašnjih istraživanja, a isto tako bazirali se na nekim bazičnim teorijama iz motorne kontrole. Generalno, problem istraživanja u okviru ove doktorske disertacije je odnos brzine izvođenja i ostvarene preciznosti šutnute lopte pri različitim modalitetima izvođenja jednog od najzastupljenijeg tehničkog elementa u fudbalu - instep udarca. Generalni cilj istraživanja je predstavljao ispitivanje brzine izvođenja šuta u fudbalu i ispoljene preciznosti u zavisnosti od instrukcija koje se zadaju ispitanicima, veličine mete u koju se gađa i primijenjenog trenažnog modela. Ostvarena preciznost je procjenjivana preko srednje radijalne greške (SRG), centriodne radijalne greške (CRG) i bivarijantne varijabilne greške (BVG) koje predstavljaju izmjerene prostorne greške u dvodimenzionalnom koordinatnom sistemu, kao i preko grešaka koje prate odstupanja pogodaka u jednoj dimenziji, tj. po horizontalnoj (X) i vertikalnoj osi (Y). Brzina šuta je analizirana preko relativnih (Vrel) i apsolutnih vrijednosti (V). Saglasno postavljenim ciljevima istraživanja izvedena su tri eksperimenta. Prvim eksperimentom se utvrđivalo da li postoji efekat faktora veličina mete i faktora instrukcija na varijable za procjenu brzine i preciznosti šuta. Uzorak za ovaj eksperiment su činila 33 ispitanika, muškog pola, prosječnog uzrasta 15 godina (+/- 0,9), prosječne visine 168,5 cm (+/- 7,2) i prosječne težine 55,5 kg (+/- 5,5). Drugim eksperimentom se ispitivao efekat faktora instrukcija za gradiranje brzine izvođenja udaraca na odgovarajuće varijable za procjenu brzine i preciznosti. U ovome istraživanju je učestvovalo 13 ispitanika, muškog pola i prosječnog uzrasta od 15 godina (+/- 1,6), visine 180,4 cm (+/- 5,1) i težine 70,3 kg (+/- 5,8)...

2. Zhang, Libiao. Modelling uncertain decision boundary for text classification.

Degree: 2016, Queensland University of Technology

Text classification is to classify documents into predefined categories by learned classifiers. Classic text classifiers cannot unambiguously describe decision boundary between relevant and irrelevant documents because of uncertainties caused by feature selection and knowledge learning. This research proposes a three-way decision model for dealing with uncertain decision boundary based on rough sets and centroid solution to improve classification performance. It partitions training samples into three regions by two main boundary vectors, and resolves the boundary region by two derived boundary vectors to generate decision rules for making 'two-way' decisions.
