BOGATI UPORABNIŠKI VMESNIKI PRI SISTEMIH ZA UPRAVLJANJE Z ZNANJEM
Tadej Volgemut, 2011, bachelor thesis/paper

Abstract: Diplomsko delo predstavlja uporabniške vmesnike z večjim poudarkom na bogatih uporabniških vmesnikih. Opisuje imperativni in deklarativni pristop gradnje vmesnikov, in podaja napotke za dobre uporabniške vmesnike. Predstavlja pomen miselnih vzorcev, njihov izvor, in kako se jih pravilno lotiti. Opisana je raziskava tehnologij in orodij za izdelovanje RIA (bogata internetna aplikacija) in izvedena njihova primerjava. Raziskava je zaključena z izdelavo aplikacije, ki združuje področje upravljanja znanja in bogatih uporabniških vmesnikov, z izbranimi orodji in tehnologijami. Narejena aplikacija omogoča ustvarjanje miselnih vzorcev na uporabniku prijazen in intuitiven način. Miselni vzorci so lahko deljeni med več uporabnikov.
Keywords: miselni vzorci, upravljanje z znanjem, bogati uporabniški vmesniki, Microsoft Silverlight, Microsoft Expression Blend

Comparative study of various renewable fuels blends to run a diesel power plant
Eloisa Torres Jiménez, Marta Svoljšak, Andreja Gregorc, M. P. Dorado, Breda Kegl, 2010, published scientific conference contribution

Abstract: In this paper bioethanol/diesel and bioethanol/biodiesel blends, at several concentrations and temperatures, are studied to find its possible commercial usage as a fuel to run a diesel power plant. The tested fuels were: net mineral diesel fuel (D100) , 5 % bioethanol/diesel fuel blend (v/v) (E5D95), 10 % bioethanol/diesel fuel blend (v/v) (E10D90), 15 % bioethanol/diesel fuel blend (v/v) (E15D85), neat biodiesel (B100), 5 % bioethanol/biodiesel blend (v/v) (E5B95), 10 % bioethanol/biodiesel blend (v/v) (E10B90), and 15 % bioethanol/biodiesel blend (v/v) (E15B85). The fuels were tested at: 30, 25, 8 and -18 C. This paper shows the observations done in 8 samples during 5 weeks. After each week, each sample was overviewed, and changes related to stability, colour and aggregation were recorded. It has been proved that additives are not necessary to ensure stability of bioethanol/biodiesel blends under low temperature conditions, as the phase separation never happens. But in case of bioethanol/diesel blends some additives are necessary to keep stability under low temperature conditions. Based on this study, it can be concluded that blends of biodiesel fuel with bioethanol up to 15% can be used to fuel a diesel power plant if engine performance tests corroborate it. The same conclusion can be applied to blends of diesel fuel with bioethanol up to 15% blends if additives to keep stability are added.

PEG modified poly(amide-b-ethylene oxide) membranes for CO2 separation
Anja Car, Črtomir Stropnik, Wilfredo Yave, Klaus-Viktor Peinemann, 2008, original scientific article

Abstract: In the present work, membranes from commercially available Pebaxr MH 1657 and its blends with low molecular weight poly(ethylene glycol) PEG were prepared by using a simple binary solvent (ethanol/water). Dense film membranes show excellent compatibility with PEG system up to 50 wt.% of content. Gas transport properties have been determined for four gases (H2, N2, CH4, CO2) and the obtained permeabilities were correlated with polymer properties and morphology of the membranes. The permeability of CO2 in Pebaxr/PEG membrane (50 wt.% of PEG) was increased two fold regarding to the pristine Pebaxr. Although CO2/N2 and CO2/CH4 selectivity remained constant, an enhancement of CO2/H2 selectivity was observed. These results were attributed to the presence of EO units which increases CO2 permeability, and to a probable increase of fractional free-volume. Furthermore, for free-volume discussion and permeability of gases, additive and Maxwell models were used.

Izdelava e-gradiv na primeru matematičnih metod v logistiki
Marjan Sternad, Tomaž Kramberger, Maja Fošner, 2009, published scientific conference contribution

Abstract: Fakulteta za logistiko izvaja študij s kombinacijo tradicionalnega študija in študija s pomočjo tehnologije, ki jo svetovna strokovna literatura imenuje Blended Learning, pri nas pa smo ga poimenovali Blend FL na osnovi nam lastnih njegovih prilagoditev in osmišljenja. Blend FL je dinamični sistem za izdelavo, vzdrževanje in upravljanje elektronskih gradiv. Z njimi bomo hitreje izdelovali boljša e-gradiva, ki bodo fleksibilna, standardizirana in prilagodljiva za vsakega posameznika. Pri izdelavi e-gradiv gre za hitrejšo in sodobnejšo digitalno predelavo iz Worda ali LaTeX-a v spletno stran.

UPORABNIKU PRIJAZEN SISTEM ZA E-UČENJE IN E-GRADIVA
Uroš Orešič, 2012, undergraduate thesis

Abstract: Sistem Blend.Fl, ki smo ga razvili na Fakulteti za logistiko, vsebuje module, ki so bili oblikovani v namen izboljšave uporabnikove interakcije z učnimi viri na spletu. Funkcionalnosti kot so označevalec vsebine, shranjevanje napredka, viri v povezavi, tiskanje z označbami in interaktivne naloge omogočajo uporabniku personalizacijo učnega procesa. V tej diplomski nalogi obravnavamo ideje in implementacijo teh modulov.

POSODOBITEV SPLETNEGA PORTALA E-GRADIV FAKULTETE ZA LOGISTIKO
Zoran Kajba, 2013, undergraduate thesis

Abstract: V diplomskem delu opišemo posodobitev portala Blend.Fl iz sistema za upravljanje vsebin Joomla 1.0 na verzijo 2.5. Portal Blend.Fl vsebuje komponente za delo z elektronskimi gradivi. Opišemo sistem za upravljanje vsebin Joomla in njegove razširitve, kjer smo implementacijo komponent dodatno preučili in prikazali. Predstavimo tudi komponenti sistema e-gradiv in njuno delovanje. Komponenti sta namenjeni urejanju poglavij in gradiv, namenjenih študentom Fakultete za logistiko, v povezavi s hibridnim izobraževanjem.
