Low Cost Video on Demand Platform Based on Open Source Software
Video on demand servers are complex, expensive and inappropriate to be used in low-budget environments. This work proposes an approach to use an open source web server and an open source content management system as a video on demand platform for public web purposes. Pseudo-streaming over the hyper text transfer protocol is introduced with the supporting web server features. A practical implementation of the solution is provided with the extensions made to Wordpress content management system.

User behavior analysis based on Identity management systems’ log data
Identity Management Systems (IdM systems) are repositories where users’ security credentials are kept and managed. One of many tasks performed by IdM system is an authentication and authorization of users while they are using applications. In case where IdM systems are organized as central repository, which means that authentications and authorizations for different applications are carried out on one central IdM system. This case is common for enterprises with more than 50 employees where various aspects of users’ behavior can be analyzed. By applying machine learning method SVM (Support Vector Machines) on IdM system log data with application on searching employees that are acting enthusiastically within working day, we showed that analysis of IdM systems log data can be successfully applied for analyzing employees behavior within an enterprise.

A Tool for Development and Evaluation of Accessible Web 2.0 Applications
Many Web applications are not designed in a way which would allow persons with disabilities and older adults to fully benefit from modern Web 2.0 services. Implementation of Web accessibility has traditionally been plagued by inefficient tools and tedious evaluation procedures. The I2Web project is developing software frameworks that will support Web developers better during the implementation phase and is introducing new methods for accessibility validation based on simulation of user preferences and device models.

Računalništvo v oblaku v telekomunikacijah in primeri uporabe
Računalništvo v oblaku temelji na konceptu, ki je v telekomunikacijah že dolgo poznan kot abstrakcija infrastrukture, platforme in storitev. Pomembna razloga za njegov razmah sta vedno večja razširjenost širokopasovnih povezav ter napredek na področju virtualizacije strojne opreme, ki danes omogoča popolno avtomatizacijo in optimizacijo delovanja velikih strežniških farm.
Kljub številnim ponudnikom virtualizacijske programske opreme, se to področje ne bi tako razmahnilo brez prisotnosti velikih ponudnikov infrastrukture in storitev v oblaku, ki so z agresivnim oglaševanjem in inoviranjem na področju poslovnih modelov ozavestili kupce in znižali vstopno bariero za uporabnike in razvijalce.

Nadzor nad razpršenimi viri v Smart Grids z IEC 61850
Efficient and reliable transmission and distribution of electricity is a fundamental requirement for providing societies and economics with essential energy resources. This resulted in a new conception of classical power grids – Smart Grid. The key element in smart grid is increased information sharing. Communication as a whole is the backbone of Smart Grid.
In this article we analyze standard IEC 61850, which defines communication principles and modeling methods of substation equipment and we give example of employment of standard IEC 61850 for monitoring and managing distributed energy resources.

IPv6 in Internet prihodnosti
Internetni protokol verzije 6 (IPv6) predstavlja neizogiben korak k modernizaciji zmogljivosti raznovrstnih omrežnih rešitev, s tem pa tudi omrežno tehnologijo sedanjosti in prihodnosti. Prispevek podaja celovit konceptualni pregled tehnologije IPv6 s poudarkom na tehnoloških novostih, prednostih in pomanjkljivostih, ter novih področjih aplikativne uporabe.
Pojem digitalne dividende pri razvoju širokopasovnih mobilnih omrežij
Digitalna dividenda je pojem, ki je povezan s prehodom na digitalno oddajanje televizijskih programov. Sproščeni del spektra je pogoj za razvoj novih komunikacijskih omrežij, ki bi lahko zmanjšala digitalno ločnico in omogočila dostop do interneta na podeželju.
Converged TV over IMS
With the gradual popularization of large screen, high performance and low power-consumption terminals, the dream of employing personal portable terminals anytime and anywhere to enjoy multimedia services such as streaming becomes reality. With IMS playing a major role in future, the vision of converged “quadruple play” (combined telephony, Internet, TV and mobile) services can become a reality.
