PRIMERJAVA MOBILNIH PLATFORM ZA RAZVOJ POSLOVNIH APLIKACIJ
Rok Arnuš, 2010, undergraduate thesis

Abstract: V diplomskem delu smo pregledali obstoječe mobilne platforme za razvoj aplikacij. Te se uporabljajo na pametnih telefonih, kot tudi na srednje zmogljivih mobilnih telefonih. Razložili smo, kaj je pameten telefon in kakšne so njegove značilnosti. Podrobneje smo predstavili platformi Windows Mobile in Andorid, saj smo ju uporabili v praktičnem delu diplomske naloge. Predstavili smo področja, na katera naleti razvijalec poslovnih aplikacij za mobilne platforme. Nato smo pregledali mehanizme, ki so na voljo za obvladovanje teh konceptov. To so razvojno okolje, shranjevanje podatkov, grafični vmesniki, procesi v ozadju, povezovanje s strojno opremo in drugi. Razvili smo tudi prototip aplikacije za informatizacijo potnih nalogov na obeh platformah. Po predstavitvi same aplikacije smo pripravili še poglavji z implementacijo. V zadnjem poglavju smo zbrali rezultate primerjave.
Keywords: mobilne platforme, lokacijsko naravnane storitve, .NET Compact Framework, Android Application Framework

RAZVOJ GENERATORJA POSLOVNIH SPLETNIH APLIKACIJ
Boštjan Martinek, 2010, undergraduate thesis

Abstract: Naloga obravnava razvoj generatorja poslovnih spletnih aplikacij. Temelji na trinivojski arhitekturi. Za potrebe manjšega podjetja s področja inženiringa programske opreme je bil razvit generator, ki temelji na odprtokodnih rešitvah Apache, MySql, GWT in Eclipse. Podan je kratek pregled obstoječih generatorjev. Ugotovili smo, da noben od njih v celoti ne zadošča zahtevam konkretnega podjetja. Razvit je bil prototip generatorja poslovnih aplikacij in preizkušen na več primerih. Delovanje generatorja je zanesljivo, uporaba je enostavna in prihrani programerjem veliko časa. Glavna slabost je premajhen nabor vizualnih elementov.
Keywords: Generator poslovnih spletnih aplikacij, RAD (Rapid Application Development), GWT (Google Web Toolkit)

Ecological alternatives to the reduction and oxidation processes in dyeing with vat and sulphur dyes
Mojca Božič, Vanja Kokol, 2008, review article

Abstract: This article gives a summary of the most commonly used ecologically unfriendly processes for the reduction and oxidation of vat and sulphur dyes. It also describes the new alternatives that are in the development stage and could be important in the near future. Sodium dithionite as the dominant reducing agent produces large amounts of sodium sulphate, and also toxic sulphite and thiosulphate as by-products. Consequently, high amounts of hydrogen peroxide and alkali are required for the treatment of effluents, which add to the cost of the process. Attempts have been made to use organic biodegradable reducing agents, enzymes, catalytic hydrogenation, and also indirect or direct, electrochemical reductive methods that employ a redox mediator (electron-carrier). The reduction has also been carried out via the dye radical molecule or, in the case of indigo, by direct electrochemical reduction using graphite as the electrode material. Physical techniques, for example using ultrasound, magnetic fields or UV have been shown to be effective only when used to accelerate methods using classical reduction and oxidation processes. However, although these methods offer some environmental benefits, there is still no satisfactory alternative reducing and/or oxidising agent available today.
Keywords: textile dyeing, vat dyes, sulphur dyes, reduction, oxidation, catalysis, ecology, organic agents, electrochemistry, ultrasound, magnetic field, UV application, biotechnology

Modeling distributed real-time applications with specification PEARL
Roman Gumzej, Shourong Lu, 2007, original scientific article

Abstract: The methodology of hardware/software co-design of embedded control systems with Specification PEARL is presented. Hardware and software are modeled with the language Specification PEARL, which has its origins in standard Multiprocessor PEARL. Its usefulness is enhanced for modeling hierarchical and asymmetrical multiprocessor systems, and by additional parameters for schedulability analysis. Graphical symbols are introduced for its constructs to enable graphical modeling while maintaining the semantical background. It is meant to be a superlayer for programs, based on the PEARL programming model. To model program tasks, Timed State Transition Diagrams have been defined. The model of a co-designed system is verified for feasibility with co-simulation. The resulting information should be used when considering changes in a current design with the goal of producing a temporally feasible model. To support dynamic re-configurations, configuration management is introduced into the models. Since UML is becoming a de facto standard also for designing embedded control systems, and since Timed State Transition Diagrams and State Chart Diagrams share great similarity, an interface of the methodology to UML 2 is defined, using UML's extension mechanisms.
Keywords: specification language, application modeling, co-design, co-simulation, configuration management, PEARL, UML
