In this paper we show several segments of program solutions which are a part of the Croatian Linguistic System (CLS) that is being developed in several ways and aims at achieving the final integration of all modules. Although the system aims at programmatically connecting all areas of linguistics (from phonetics to discourse), in the demonstration we will show only the segments that are related to general lexicon building (which includes a standard and terminological dictionary of the Croatian language) and will be connected with online repositories and encyclopedias. These program segments are searching for neologisms in documents (i.e. words that have not been marked in the general lexicon), generating grammatical forms of such words if they are changeable and saving them into a lexicon, adding semantic markups (like morphosyntactic) characteristics, and, finally, monitoring Croatian words in space and time.

network framework ,automatic dictionary generation ,integration of lexicographic web information ,linked open data - Abstract
In this paper we describe an online application which connects various Croatian lexicographical sources (the standard dictionary, professional terminology, and encyclopedias) into a new network framework, which solves the problems of the currently available network solutions and offers new features. Although developed for the formation and processing of the professional terminology of technical sciences (primarily engineering), this framework is easily extensible to all other science areas (humanities, medicine, architecture, etc.). From a word formation standpoint, this framework provides an automatic generation of a temporary dictionary of a given text (entered or taken from the web), comparison of and updating a permanent dictionary with a temporary one (detection of neologisms), an automatic display (standard, professional and encyclopedic) of definitions of the words from the main dictionary or external (network) sources of a given text. From the point of view of processing, the framework enables a classic text analysis (frequency, concordances, statistics), converting the collected data (e.g. technical words) to the linked open data (LOD), and storing it into the Virtuoso triplestore repository. On this data, a variety of professional ontologies for viewing and searching can be developed.

Zotero ,program za upravljanje bibliografskim bilješkama ,knjižničarstvo - Abstract
Zotero je program otvorenog koda unutar Mozzila WEB-preglednika namijenjen automatskom dohvaćanju, uređivanju i upravljanju bibliografskim bilješkama ; eksportiranju istih u razne formate i izradi bibliografije različitih stilova. Razvili su ga Center for History and New Media na George Mason University. Takvi programi za upravljanje bibliografskim bilješkama (reference managers) arhiviraju i organiziraju radove koje citira korisnik. (Muldrow, Yoder ; 2009) Namijenjeni su istraživačima, nastavnicima, studentima i knjižničarima za stvaranje osobnih baza podataka koje sadrže isključivo njima najvažnije bibliografske bilješke. Zotero promiče novi pristup u razvoju pomagala za upravljanje bibliografskim bilješkama. Za razliku od svojih prethodnika (EndNote, RefWorks, ProCite i sl.), koji predstavljaju samostalne aplikacije, Zotero je svoje mjesto našao upravo tamo gdje korisnici često borave – na mreži, tražeći informacije, pa je ugrađen u popularan WEB preglednik – Mozilla Firefox. Osim primjene uspješnih osobina svojih prethodnika, iskorištava i dostignuća modernih softvera i mrežnih aplikacija: iTunes-a i del.icio.us-a, osiguravajući interakciju, stavljanje oznaka i napredno pretraživanje. Jednako dobro funkcionira i offline, osim što tada, dakako, ne dohvaća online jedinice pohranjene u zbirkama. Članak opisuje njegove mogućnosti i kompatibilnost s određenim standardima, naglašavajući njegovu primjenljivost u knjižničarstvu. Detaljnija usporedba pojedinih programa za upravljanje bibliografskim bilješkama nije predmet ovog rada.

web publishing ,linear and convex programming - Abstract
Scriptrunner is a web application that enables editing and running programs written in various programming languages. Currently supported languages are: C/C++, Java, Fortran, Pascal, PHP, HTML/Javascript, Matlab, Mathematica, Scilab and Octave. The goal of Scriptrunner is writing and publishing of digital books. Each such book becomes "live" because the programs with the preferred, regularly different, input data can be called from it. This article shows how to write a classbook for our students about linear and convex (semidefinite) programming, with many on-line examples. It is well known that most analysis and designs problems in robust and nonlinear control can be formulated as global optimization problems. In the last decade, optimization over LMIs has established itself as a popular convex relaxation technique in the systems and control community. We offer a useful on-line solution.

Thwe existence of symmetric block design for (71, 21, 6) was doubtful until the discovery of Z. Janko and T. van Trung of the so-called "non-human" design. In this paper we have classified designs with the above parameters, admitting all possible actions of the nonabelian group of order 21 on them, which is indeed the full automorphism group of the Janko-van Trung design. We have proved that there is only one symmetric block design for (71, 21, 6), together with its dual, with the Frobenius group of order 21, namely the Janko-van Trung design.

This article deals with the control of robotic convoy system using the potential field method (PFM). An analitic fuzzy approach based on the principles of kinematics of rigid body is proposed. We assume that all robots are of the differential drive which is the most common structure in the practical applications of so-called service mobile robots. The PFM in such systems is used to generate robots desired trajectories. Properties of the method are illustrated and discussed on the simulation examples of obstacle avoidance.

Monte Carlo metoda je numerička metoda rješavanja matematičkih problema slučajnim uzorkovanjem velikog broja varijabli. Koristi se za rješavanje problema koji su prekomplicirani za riješiti analitički. U web2py mrežnom okviru je izrađena on-line Monte Carlo simulacija s primjerima vezanim za slaganje tolerancija odnosno dimenzija i utjecaj tolerancija elektroničkih komponenti na strujni krug. Za opis raspodjele tolerancija je korištena normalna distribucija. PERT metoda skupa s Monte Carlom može procjeniti trajanje projekta što je također simulirano u aplikaciji. Monte Carlo simulacija povezana s Latin hypercube uzorkovanjem je korištena u obliku preinačenog mcerp 0.11 Python modula. The Monte Carlo method is a numerical method of solving mathematical problems by random sampling a large number of variables. It is used for obtaining numerical solutions to problems which are too complicated to solve analytically. On-line Monte Carlo simulation is made in web2py framework with examples based on tolerance stackup and effects of electrical component variations in electrical circuit. Normal distribution is used to describe tolerance range. PERT method used with Monte Carlo can estimate the time needed to complete given project which is also shown in web application. Monte Carlo method that uses Latin hypercube sampling is used with Python module mcerp 0.11.

U ovom diplomskom radu dat je kratak pregled o tome što čini sustave poslovne inteligencije koja je bila osnova za izradu aplikacije, nakon čega slijedi opis tehnologija koje su se koristile prilikom izrade. Na kraju se nalazi detaljan pregled aplikacije s uputama za korištenje. Osnova na kojoj je rađena aplikacija je mogućnost prikupljanja podataka preko mrežnog preglednika, sve u svrhu spremanja na udaljenom serveru i kasnijem dohvaćanju tih istih podataka. Organizacija strukture aplikacije je poput wiki sustava koji su se pokazali uspješni za suradnju više pojedinaca koji međusobno nisu u osobnom kontaktu. Stoga je bilo potrebno koristiti moderne mrežne tehnologije za izradu obrazaca, sučelja i alata koji korisnicima mogu pružiti rad unutar mrežnog preglednika. Osim pružanja mogućnosti rada unutar mrežnog preglednika pažnja je bila posvećena izradi alata koji svojim korištenjem daju osjećaj interaktivnosti na razini lokalnog računalnog programa. This thesis summarizes the accounting systems of business intelligence that was the basis for the development of application, followed by a description of the technologies that were used in the making. Finally, there are detailed examination of the application with instructions for use. The basis on which the application is made is the opportunity to collect data via web browser all in order to save it on a remote server and later retrieving those same data. The organization structure of the application is like a wiki system, which proved successful for cooperation of individuals who are not in personal contact. Therefore, it was necessary to use modern network technologies to produce forms, interface and tools that can offer users capabilities of working in the web browser. In addition to providing work opportunities within web browser, attention was paid to the development of tools that its use gives a sense of interactivity at the level of the local computer program.

U okviru ovog završnog rada opisan je algoritam pronalaska puta. Algoritam je sposoban pronaći put od početne pozicije do cilja, a da pritom izbjegava prepreke uz uvjet optimalnosti. U prvom poglavlju dan je kratak opis razvojnog okruženja algoritma u Pythonu, zatim opis rada algoritama. Algoritam koristi heuristiku, te je kratko objašnjeno što je heuristika i njena važnost. \Načinjeni program može učitati realnu sliku prostora te iz slike prikupiti informacije o objektima koje je potrebno izbječi da bi se došlo do traženog cilja. Za obradu slike korišten je OpenCV u sprezi s Pythonom. Također su opisana dosadašnja istraživanja u području traženja puta.

U ovom radu izvodi se opći upravljački algoritam za istodobno stabiliziranje i praćenje trajektorija podupravljanih nelinearnih mehaničkih sustava (UNMS) s električnim, pneumatskim i hidrauličkim pogonima (aktuatorima). Istodobna stabilizacija i praćenje trajektorija odnosi se na stupnjeve slobode gibanja sustava, a obuhvaćaju se neholonomni sustavi drugog reda i sustavi sa spregom ulaznih veličina. Algoritam rješava probleme koji nastaju zbog podupravljanosti, zanemarivanja dinamike pogona i zanemarivanja statičkog trenja. S njim su poboljšane značajke zatvorenog upravljačkog kruga u odnosu na sustave sa zanemarenom dinamikom pogona i/ili zanemarenim statičkim trenjem kakvi se često koriste. Rješavanje ovakvih problema zahtijeva upravljačke algoritme temeljene na regulatorima s promjenjivom strukturom. Matematička jednostavnost novo uvedenog algoritma omogućuje laku ugradnju u računalne programe, pa je algoritam pogodan za realizaciju u praksi. Značaj ovog istraživanja leži u upravljačkom zakonu koji svojom uporabom omogućuje upravljanje proizvoljno odabranim stupnjevima slobode gibanja sustava s ciljem zadovoljenja kvalitativnih značajki regulacije. To rezultira stabilnim i robusnim ponašanjem podupravljanih sustava. Control algorithm for simultaneous stabilizing and trajectory tracking of underactuated nonlinear mechanical systems (UNMS) with electrical, pneumatic and hydraulic actuators is carried by the paper. Simultaneous stabilization and trajectory tracking refer to degrees of freedom of the system, where UNMS include second order nonholonomic systems and systems with input coupling. The algorithm solves problems that arise due to the underactuation, neglecting actuators dynamics and neglecting static friction. By use of the algorithm, the closed loop system achieves better performances than the systems with neglected actuator dynamics and/or neglected static friction, as often the case is. Control algorithms based on the variable structure controllers are needed for solving these problems. Mathematical simplicity of the new algorithm enables simple implementation in computer applications and because of that the algorithm is suitable for putting into practice. The paper is significant due to the control law; it enables control of arbitrary chosen degrees of freedom aiming to meet the qualitative performances of control. The result is stable and robust behaviour of the underactuated systems.
