This paper describes the web application used by employees of the School of Electrical Engineering in Belgrade. The application is based on contemporary open source Java web technologies (including frameworks such as Spring, JSF, Hibernate, etc.). They were combined together into an advanced system that provides an environment for the rapid application development, high modularity and configurability. Paper describes main groups of application functionalities related to teaching process and financial operations, as well as additional functionalities. Application three-tier architecture is described in detail, with the description of technologies used in each tier. Application development environment is presented including build process management. Also, the security solution is described, as well as distributed computing model chosen for communication with other information systems within the School of Electrical Engineering.
Sažetak-Algoritmi pretraživanja omogućavaju da se u skupu rezultata pronađe željeni podatak na osnovu određenog identifikatora. Kao posebno zanimljiva klasa algoritama pretraživanja ističe se A* koji je poznat po preciznosti i performansama koje ostvaruje. Iako su razvijeni algoritmi koji u određenim primenama postižu bolju efikasnost, A* predstavlja jedan od najviše korišćenih. Ovakvi grafovski algoritmi se mogu predstavljati i grafički, tako da se za njihovo razumevanje u savremenom obrazovanju često koriste i interaktivni vizuelni simulatori, a pregled najčešće korišćenih će biti napravljen u ovom radu.Ključne riječi -algoritmi pretraživanja, grafovski algoritmi, a*, softverski simulatori Abstract -Search algorithms make possible to find the desired result in the dataset, based on certain identifiers. As a particularly interesting class of these algorithms, A* is emphasized by its precission and performance. Although more efficient algorihms have been developed for certain applications, A* is one of the most used ones. In order to facilitate understanding, it's possible to graphicaly represent these algorithms. In this way, users have an overview of the activities that take place in an algorithm. Therefore, there is a large number of visual simulators whose overview is also given in this paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
