Avtomatizacija proizvodne linije za izdelavo robnih trakov ABS s krmilnikom SIMATIC S7-1515T-2PN
Žiga Andrejčič, 2020, undergraduate thesis

Abstract: V zaključnem delu je opisana linija za izdelavo ABS robnih trakov. Trakovi se uporabljajo v zaključnih delih mizarstva. Opisan je izgled linije in njeno delovanje. Predstavljena je programska in strojna oprema uporabljena za avtomatizacijo linije. Za krmiljenje linije je uporabljen programirljiv logični krmilnik Siemens družine 1500. Podrobneje je razložena izdelava programa za avtomatizacijo.
Keywords: avtomatizacija, programirljiv logični krmilnik, ABS robni trakovi

Konstruiranje dvižnega mehanizma avtomatsko vodenega vozila
Tea Andrejčič, 2020, master's thesis

Abstract: V magistrski nalogi je predstavljeno konstruiranje dvižnega mehanizma, z mehanizmom za odvzem in odlaganje tovora, za AGV vozilo. Predstavljena je tehnologija vozil in njihovo delovanje. Magistrska naloga zajema iskanje primerne rešitve na podlagi že izdelanega modela vozila in izdelavo zahtevnika. Prikazani so preračuni za izbor potrebnih komponent. S pomočjo programa Solidworks sta bila izdelana modela obeh mehanizmov, ki sta bila nato združena skupaj in nameščena v obstoječ model vozila. Na koncu je prikazan končni model, ki dosega vse zadane zahteve ter tehniška dokumentacija, ki omogoča fizično izdelavo modela.

Snovanje orodja za tlačno litje
Tea Andrejčič, 2017, undergraduate thesis

Abstract: V diplomskem delu je prikazan postopek snovanja orodja za tlačno litje. Predstavljeno je določanje parametrov in preračuni za polnitev puše ter širino odzračevalnih kanalov. Model orodja se izdeluje v programu Creo 2.0. Predstavljene so tudi simulacije dveh različic stiska v programu MAGMASOFT, s pomočjo katerih so bile predhodno videne težave pri zalitosti odlitka. Te so bile po prikazu simulacij in na podlagi izkušenj konstrukterjev odpravljene, tako da so po fizični izdelavi orodja pri litju dobili odlitke v skladu s kupčevimi zahtevami.
Keywords: tlačno litje, orodje za tlačno litje, orodjarstvo, aluminijeve zlitine, snovanje

Prognostic factors of choroidal melanoma in Slovenia, 1986-2008
Boris Jančar, Marjan Budihna, Brigita Drnovšek-Olup, Katrina Novak-Andrejčič, Irena-Hedvika Brovet-Zupančič, Dušica Pahor, 2016, original scientific article

Abstract: Introduction: Choroidal melanoma is the most common primary malignancy of the eye, which frequently metastasizes. The Cancer Registry of Slovenia reported the incidence of choroid melanoma from 1983 to 2009 as stable, at 7.8 cases/million for men and 7.4/million for women. The aim of the retrospective study was to determinate the prognostic factors of survival for choroidal melanoma patients in Slovenia. Patients and methods: From January 1986 to December 2008 we treated 288 patients with malignant choroidal melanoma; 127 patients were treated by brachytherapy with beta rays emitting ruthenium-106 applicators; 161 patients were treated by enucleation. Results: Patients with tumours thickness < 7.2 mm and base diameter < 16 mm were treated by brachytherapy and had 5- and 10-year overall mortality 13% and 32%, respectively. In enucleated patients, 5- and 10-year mortality was higher, 46% and 69%, respectively, because their tumours were larger. Thirty patients treated by brachytherapy developed local recurrence. Twenty five of 127 patients treated by brachytherapy and 86 of 161 enucleated patients developed distant metastases. Patients of age >/= 60 years had significantly lower survival in both treatment modalities. For patients treated by brachytherapy the diameter of the tumour base and treatment time were independent prognostic factors for overall survival, for patients treated by enucleation age and histological type of tumour were independent prognosticators. In first few years after either of treatments, the melanoma specific annual mortality rate increased, especially in older patients, and then slowly decreased. Conclusions: It seems that particularly younger patients with early tumours can be cured, whereby preference should be given to eyesight preserving brachytherapy over enucleation.
