Opis: Magistrska naloga obravnava vrednotenje in izbiro tehnoloških rešitev za izdelavo statorjev elektromotorja. Izbrano podjetje, s katerim smo sodelovali pri izdelavi magistrske naloge, se vse pogosteje sooča z izbiro tehnoloških rešitev za izdelavo elektromotorjev in njihovih podsestavov. Zato smo se odločili za snovanje odločitvenega modela, ki bo omogočal hitro in enostavno vrednotenje tehnoloških rešitev za izdelavo statorjev. V magistrski nalogi smo predstavili razvoj in delovanje odločitvenih modelov po kombinirani odločitveni metodi utežene vsote in odločitvenih dreves ter odločitveni metodi DEX. V nadaljavanju smo analizirali alternative, odločitvene modele in rezultate primerjali in ugotavljali njihovo skladnost. Odločitveni modeli po obeh metodah pomagajo ovrednotiti najboljšo tehnološko rešitev na nivoju dobavitelja tehnološke rešitve za izdelavo statorjev. V modelu, izdelanem po kombinirani metodi utežene vsote in odločitvenih dreves, smo upoštevali tudi verjetnost pojavitve napovedanih proizvodnih količin, s čimer smo poskusili izbiro še dodatno izboljšati in čim bolj zmanjšati odločitveno tveganje. Zaradi kompleksnosti odločitvenega problema smo odločanje pri obeh odločitvenih modelih razdelili na dve stopnji in tako dosegli boljšo strukturiranost in preglednost odločitvenega postopka. Iz obeh odločitvenih modelov smo dobili enako razvrstitev izbranih alternativ in tako ugotovili, da sta modela primerljiva. Najbolje ovrednoteni dobavitelj strojne opreme je z Japonske in se tudi v realnosti izkazuje kot najboljši izmed treh ponudnikov strojne opreme za izdelavo statorjev elektromotorjev. Iz tega lahko sklepamo, da sta odločitvena modela pravilna in primerna za realizacijo v praksi.

Opis: Tannin is a very versatile industrial material used for many applications. During tannin production, a residue is produced, which consists of 10 – 15 % sodium acetate solution with up to 10 % water-soluble wood resins by mass. Since it contains a high portion of acetate, it can be useful for anaerobic digestion to produce biomethane, whereas wood resins may exhibit inhibitory effects. In order to test the biodegradability of wood resin residue, several batch tests were performed with two approaches. In the first approach, co-digestion with corn-silage and animal waste was performed utilizing suspended biomass inoculum. In the second approach, co-digestion with pulp and paper wastewater was performed utilizing granular biomass inoculum. In the first approach, the results showed partial inhibition of degradation using mixtures of 25.6 % and total inhibition using 100.0 % of wood resin. Maximum biodegradability achieved was 83.4 %. In the second approach, the results showed partial inhibition of degradation using mixtures of 1.7 and 3.3 % of wood resin. Maximum biodegradability achieved was 64.3 %. Because the second approach enabled us to process larger quantities of wood resin (larger COD load), a pilot experiment of anaerobic co-digestion with pulp and paper wastewater was performed, utilising similar conditions to the considered full-scale treatment. The results showed COD degradation between 70.1 and 81.7 % and a potential increase in total produced biomethane of 36 – 39 %, with no significant adverse effects. Wood resin residue yielded 45 – 50 m3 of biomethane per tonne, which exhibits a good potential for biomethane production. If used for biomethane production in pulp and paper wastewater treatment, the valorisation value of the wood resin residue is between 54,500 € and 94,000 €, which makes the presented treatment also an economically viable option.

Opis: The talk builds on an old observation that the order of attributive adjectives is universal (see for example Hetzron 1978, Sproat and Shih 1991, etc.). This also holds for adjectives for size, shape and color which seem to universally come in the order size > shape > color. One account of such adjective ordering restrictions was offered by the cartographic approach to syntax, see for example Cinque & Rizzi (2008) for an overview of the cartographic program. The core idea of this approach is that phrases consist from lexical heads which are dominated by hierarchies of functional projections. Crucially, the order of functional projections in the hierarchies is argued to be universal. This also holds for the noun phrase in which functional projections host, among other material, adjectives (Cinque 1994, Scott 2002). This means that the order of adjectives is universal because adjectives are hosted by functional projections which appear in a universal hierarchy. Based on this, the focus of the talk will be on the adjectives for size, shape and color as these adjectives will be used to investigate the possibility of a cognitive basis of the universal hierarchy of functional projections. Following Cinque & Rizzi (2008) and Ramchand & Svenonius (2014), general cognition will be considered as a possible source of the universal hierarchy of functional projections. Specifically, I will report on a series of experiments which are a result of joint work with Rok Žaucer and Franc Lanko Marušič and are a part of an ongoing project Probing the cognitive basis of the cartographic hierarchy of functional projections in the noun phrase (J6-7282) financed by the Slovenian Research Agency and conducted at the University of Nova Gorica. These experiments were conducted to test the hypothesis that if the universal hierarchy is dictated by general-cognition restrictions, then the order of projections hosting adjectives should be reflected in various non-linguistic cognitive processes. In the talk, I will report on the results of these experiments as well as ongoing research.
Ključne besede: adjectives, cartography, functional hierarchy, cognition

Opis: V diplomski nalogi so prikazani opisi sistema avtomatskega vodenja delilnega stroja, strukture sistema vodenja, strojnega dela računalniške opreme in programskega dela računalniške opreme ter preizkus delilnega stroja, kjer je opisan postopek preizkušanja stroja. Delilni stroj je avtomatski delilnik testa in je del linije za obdelavo testa. Njegov namen je, da velike količine testa zreže na majhne kose. Stroj ima več načinov delovanja oziroma deljenja kosov testa. Razlika med načini delovanja je vsota število kosov, ki padejo istočasno na notranji transporter, kar določa naročnik stroja oziroma projekta. Namen diplomskega dela je predstaviti sistem vodenja delilnega stroja, opisati pretvarjanje in nadgradnjo obstoječe programske kode ter pretvorbo vmesnika človek – stroj za delilni stroj, narejen v razvojnem okolju podjetja Omron, v izvedbo razvojnega okolja podjetja Siemens. V diplomskem delu so opisi celotnega sistema vodenja delilnega stroja ter pretvorbe in nadgradnje programske opreme. Opravljen je tudi preizkus delovanja avtomatsko vodenega delilnega stroja. Delilni stroj, ki je bil izdelan po zahtevah stranke, je bil uspešno preizkušen in predan stranki.
Ključne besede: Sistem avtomatskega vodenja, strojna oprema, programska oprema, delilni stroj.
