4. Vodenje pogona transporterja skladno z zakonodajo o varnosti strojev : diplomsko deloJure Knez, 2021, diplomsko delo Opis: Med izgorevanjem in čiščenjem dimnih plinov v termoelektrarni nastajajo stranski produkti, ki jih je potrebno transportirati na deponije. Za ta namen uporabljamo transportne sisteme, ki so opisani v diplomski nalogi.
V prvem delu je opis standardov, ki jih je bilo potrebno upoštevati pri izdelavi. V nadaljevanju je opis termoelektrarne Ugljevik in opis elementov enega od transporterjev. Sledi podroben opis transporterja G-1 ter njegov način vodenja.
V zadnjem delu sta predstavljena še dva možna načina vodenja, ki sta izrisana s pomočjo programskega paketa EPLAN, kateri je tudi na kratko opisan. Predstavljene so prednosti in slabosti posameznih tipov vodenja.
Ključne besede: standardizacija, standardi, termoelektrarna, vodenje pogona transporterja

5. From DCOM interfaces to domain-specific modeling language : a case study on the sequencerTomaž Kos, Tomaž Kosar, Jure Knez, Marjan Mernik, 2011, izvirni znanstveni članek Opis: Software development is a demanding process, since it involves different parties to perform a desired task. The same case applies to the development ofmeasurement systems - measurement system producers often provide interfaces to their products, after which the customersć programming engineers use them to build software according to the instructions and requirements of domain experts from the field of data acquisition. Until recently, the customers of the measurement system DEWESoft were building measuring applications, using prefabricated DCOM objects. However, a significant amount of interaction between customersć programming engineers and measurement system producers is necessary to use DCOM objects. Therefore, a domain-specific modeling language has been developed to enable domain experts to program or model their own measurement procedures without interacting with programming engineers. In thispaper, experiences gained during the shift from using the DEWESoft productas a programming library to domain-specific modeling language are provided together with the details of a Sequencer, a domain-specific modeling language for the construction of measurement procedures.

6. Simultaneous determination of phthalates, their metabolites, alkylphenols and bisphenol a using GC-MS in urine of men with fertility problemsRoman Kranvogl, Jure Knez, Alen Miuc, Ernest Vončina, Darinka Brodnjak-Vončina, Veljko Vlaisavljević, 2014, izvirni znanstveni članek Opis: A GC-MS method was successfully applied to measure simultaneously the concentrations of endocrine disrupting compounds (5 dialkyl phthalates, 9 phthalate monoesters, 3 alkylphenols and bisphenol A) in 136 male urine samples. In the present study the method was validated and concentrations of EDCs were determined. The results were compared with results from other studies. Correlations between endocrine disrupting compounds and also correlations of endocrine disrupting compounds with two semen quality parameters are presented and evaluated. Significant positive correlations were found between almost all the endocrine disrupting compounds. The parameter sum of DEHP (SUM DEHP) was positively correlated to all the endocrine disrupting compounds but negatively to two semen quality parameters. Negative correlations between the endocrine disrupting compounds and the semen quality parameters could indicate that endocrine disrupting compounds could cause reproductive problems by decreasing the semen count and quality. This research will have helped to evaluate human exposure to endocrine disrupting compounds.

7. ZAŠČITA RAČUNALNIŠKIH OMREŽIJ V VZGOJNO IZOBRAŽEVALNIH ZAVODIHJure Knez, 2014, magistrsko delo Opis: Varnost informacijskih sistemov v vzgojno-izobraževalnih zavodih je na prvi pogled videti enostavna. Vendar, kot je pokazala raziskava, na zavodih večinoma nimajo osebe, ki bi primarno skrbela za informacijski sistem. Še največkrat so to učitelji, ki poleg svojega rednega dela (poučevanja) skrbijo še za informacijski sistem in nimajo ustreznega znanja o vzdrževanju in primerni varnosti. V Sloveniji jim pri nasvetih za lokalna omrežja in strežnike svetuje Arnes, znotraj Arnesa pa glede varnosti SI-CERT in njegov projekt ozaveščanja, Varni na Internetu.
V nalogi je predstavljeno stanje varnosti v vzgojno-izobraževalnih zavodih v Sloveniji. Raziskali smo tudi dobre prakse v tujini.
Na podlagi rezultatov ankete in dobrih praks iz tujine smo podali mnenja, kaj bi lahko, za dodatno varnost informacijskih sistemov v vzgojno-izobraževalnih zavodih, storili država, Arnes in sami zavodi.
Kot pomoč zavodom pri vzpostavitvi varnega računalniškega omrežja smo pripravili tudi nasvete za vzpostavitev varnostne politike in priporočila za zaščito računalniških omrežij.
