Assessment of the load-bearing capacity of a primary pipeline
Nenad Gubeljak, Jelena Vojvodič-Tuma, Borivoj Šuštaršič, Jožef Predan, Maks Oblak, 2007, original scientific article

Abstract: High-alloyed Cr-Ni-based two-phase stainless steel (SS) cast alloys are commonly used in nuclear power plants. The mechanical equipment in these facilities can contribute to a reduction in its resistance to stable crack growth as a result of extended operating times and high temperatures. The toughness of these materials strongly depends on their delta (▫$/delta$▫) ferrite content, which spinodally decomposes into two phases with different ratios of Cr and Ni at a relatively low (slightly above 300 °C) temperature. This temperature is similar to the operating temperature of the vital parts, for example, the coolant system. The formation of two phases with the same crystalstructure but different lattice parameters causes internal elastic stresses that result in a hardness increase and an impact-toughness decrease. The result is an increased risk of crack formation in the stress-concentration zones such as the critical regions of different welded joints (e.g. "L, T, K and X" shapes). The values of the critical stress intensity factor change according to its position along the crack contour. Therefore, the aim of our study was to assess the influence of the materials' changes on the crack extension and the decrease of the primary pipeline's bearing capacity by taking account of the increased temperature and time of operation for the given loading conditions. The SINTAP (European Structural Integrity Assessment Procedure) was used for this assessment.

Application of the european SINTAP procedure to the failure analysis of a broken forklift
Nenad Gubeljak, Uwe Zerbst, Jožef Predan, Maks Oblak, 2004, original scientific article

Abstract: The recently developed European flaw assessment procedure SINTAP was applied to the failure analysis of a broken fork of a forklift. Based on the service load at failure, critical crack sizes were determined at different analysis levels of the procedure. It was shown in the present case study that the failure was caused by defective design.

RAZVOJ SISTEMA POROČANJA V JEZIKU PYTHON
Gašper Vrezovnik, 2013, master's thesis

Abstract: V raziskavi je preskušen koncept razvoja sistema poročanja v odprtokodnem in objektno usmerjenem programskem jeziku Python. Izbrani programski jezik se je izkazal kot primerno orodje za izdelavo sistema za poročanje za virtualna mobilna operaterja Debitel in IZI mobil. Izdelan je bil posnetek stanja procesov ad hoc generiranja poročil. Ugotovljene pomanjkljivosti takega načina dela so predvsem zahteva po prisotnosti operaterja in velika možnost napake zaradi napačnega zaporedja poizvedb. Razvita aplikacija omogoča dva načina dela, poimenovana »SELECT« in »PROCEDURE«. Način »SELECT« temelji na ad hoc poizvedbah, »PROCEDURE« pa na shranjenih procedurah. Trajanje izdelave poročil je bilo merjenje dopoldne in po 21. uri. Referenčne meritve ad hoc poizvedb so bile izvedene z orodjem Oracle SQL Developer. Meritve časa trajanja poizvedb, porabe pomnilnika, obremenjenosti procesorja in obremenjenosti omrežja so pokazale, da je primernejši način za izdelavo mesečnih poročil s prototipno programsko rešitvijo v načinu delovanja »PROCEDURE«. Meritve obsegajo razlike porabe virov na osebnem računalniku, ki so bile pri razvitih načinih poročanja nepomembne.

ODZIVNOST SHRANJENIH PROCEDUR
Zlatko Rednjak, 2014, undergraduate thesis

Abstract: V diplomski nalogi so predstavljene podatkovne baze, sistemi za upravljanje s podatkovnimi bazami in shranjene procedure. Raziskani so trije najbolj pogosto uporabljeni sistemi za upravljanje s podatkovnimi bazami, njihovi načini implementacije shranjenih procedur. Testirana je časovna odzivnost njihovih shranjenih procedur pod enakimi pogoji. Pri raziskovanju nam je bila v pomoč uradna dokumentacija sistemov, s članki, ki so opisovali implementacijo shranjenih procedur, in forumi. Izvedena je bila tudi študija primera, v kateri je bilo ugotovljeno, kateri sistemi zagotavljajo boljšo odzivnost shranjenih procedur.

InVance sling postopek za zdravljenje moške stresne urinske inkontinence
Dejan Bratuš, Gregor Hlebič, 2011, original scientific article

Abstract: Namen: Stresna inkontinenca urina je pri moških relativno redka in se pojavi kot posledica večjega operativnega posega, drugi vzroki stresne inkontinence urina se pri moških pojavljajo izjemoma. Ne glede na relativno majhno število prizadetih takšno uhajanje urina obolelim predstavlja velik medicinski in tudi socialni problem, saj se odpovejo normalnim dnevnim aktivnostim in se vse bolj omejujejo na domače okolje. Metode: Ena izmed možnosti zdravljenja stresne urinske inkontinence pri moških je tako imenovani InVance Male Sling sistem. Gre za minimalno invazivno kirurško metodo, pri kateri se na spodnjo stran pubične kosti z vijaki pritrdi poliesterska mrežica, ki tesni sečnico. V principu gre za sling operacijo. Rezultati: Na našem oddelku smo med letoma 2004 in 2007 z omenjeno prometodo zdravili osemintrideset bolnikov. Pri štiriintridesetih je šlo za stanje po radikalni odstranitvi prostate, pri štirih pa za stanje po transuretralni resekciji prostate. Čas spremljanja po posegu je pri vseh daljši od dveh let. Osemindvajset bolnikov navaja popolno ozdravitev (brez uporabe predlog), šest bolnikov navaja blago stresno inkontinenco (ena predloga dnevno), pri štirih bolnikih pa ni prišlo do izboljšanja. Pri nobenem bolniku nismo opažali zastoja urina ali na novo nastalih težav pri uriniranju, smo pa pri treh bolnikih srečali podaljšano gnojno izcejanje iz postoperativne rane in še pri treh kasno zavrnitev mrežice, zato smo pri teh bolnikih morali mrežico odstraniti. Imeli smo tudi bolnika z erozijo sečnice osem mesecev po posegu. Zaključek: Glede na naše rezultate lahko zapišemo, da je Invance sling operacija uspešna metoda zdravljenja moške stresne inkontinence urina z minimalnimi pooperativnimi zapleti.

The rulemaking procedure - definition, concepts and publlic participation
Iztok Rakar, Bojan Tičar, 2015, original scientific article

Abstract: The importance of delegated legislation is growing in both the quantitative and qualitative sense. Under the American system, the so-called division of rulemaking authority between the legislative and executive branch was resolved at a very early juncture and in a highly pragmatic manner by applying the fundamental principles of the legislative procedure to the level of the rulemaking procedure, which primarily implies the transparency and openness of the latter. Conversely, Continental Europe did not develop a general theory of public participation which could provide a basis for the search for solutions to the situation. The purpose of this paper is to present different concepts of the rulemaking procedure and discuss the question of public participation. We conclude that, as the quantity and complexity of societal relationships grow, it is fruitful to use the so-called problem-solving model of the rulemaking procedure as a starting point for its procedural arrangement. This allows us to focus on the role that civil society, interest groups and the general public play in the contemporary governance process.

SPLETNI VMESNIK ZA UREJANJE PODATKOV O ČLANIH DRUŠTVA
Dušan Šubic, 2016, bachelor thesis/paper

Abstract: Ker ima vsako društvo, klub ali podobna združenja določeno število članov ali pripadnikov, sem se odločil, da izdelam spletno aplikacijo za register članov. Bistvo aplikacije je, da je struktura skoraj v celoti dinamična. Kar pomeni, da uporabnik (administrator v organizaciji) poljubno dodaja ustrezna polja v register, tvori sezname, ki jih potrebuje za vodenje evidence; na primer interesi članov, status člana v organizaciji idr. Celotna struktura baze temelji na skupaj vsaj osmih tabelah, od katerih se v štiri zapisuje struktura podatkov, v dodatno eno tabelo podatki o vlogah, to je dovoljenjih za prikaz podatkov na nivoju polj, v eno tabelo se shranjujejo podatki o zalogah vrednosti lastnosti, v eni je seznam tabel in najmanj ena tabela s podatki. Tabela s podatki je običajno tabela z registrom članov (Clan). Za dodajanje novih dodatnih tabel je dovolj osnovno poznavanje MySQL-a. Vse procedure za rudarjenje po podatkih so napisane za in se izvajajo v MySQL-u. Za klicanje procedur in tvorjenje dinamičnih prikazov je uporabljen PHP. Prikaz podatkov in izvajanje zahtev pa temelji na Javascript-u. Knjižnice, ki sem jih uporabil so jQuery in jqGrid. Za prijavo za pregledovanje oz. administriranje podatkov je predvsem zaradi tega, ker Društvo Mensa že ima Google Apps, sem uporabil Googla API PHP client za preverjanje identitete. Upam, da je v tem delu dobro prikazana možnost uporabe dinamične strukture za kreiranje po obsegu podatkov manjših registrov oz. seznamov. Ravno tako lahko idejo o dinamični strukturi lahko razvijalci uporabijo pri dodeljevanju dinamičnih lastnosti že obstoječim tabelam.

Borders of communication privacy in Slovenian criminal procedure
Sabina Zgaga, 2015, original scientific article

Abstract: Due to fast technological development and our constant communication protection of communication privacy in every aspect of our (legal) life has become more important than ever before. Regarding protection of privacy in criminal procedure special emphasis should be given to the regulation of privacy in Slovenian Constitution and its interpretation in the case law of the Constitutional Court. This paper presents the definition of privacy and communication privacy in Slovenian constitutional law and exposes the main issues of communication privacy that have been discussed in the case law of the Constitutional Court in the last twenty years. Thereby the paper tries to show the general trend in the case law of Constitutional Court regarding the protection of communication privacy and to expose certain unsolved issues and unanswered challenges. Slovenian constitutional regulation of communication privacy is very protective, considering the broad definition of privacy and the strict conditions for encroachment of communication privacy. The case law of Slovenian Constitutional Court has also shown such trend, with the possible exception of the recent decision on a dynamic IP address. The importance of this decision is however significant, since it could be applicable to all forms of communication via internet, the prevailing form of communication nowadays. Certain challenges still lay ahead, such as the current proposal for the amendment of Criminal Procedure Act-M, which includes the use of IMSI catchers and numerous unanswered issues regarding data retention after the decisive annulment of its partial legal basis by the Constitutional Court.
