The ERK 2019 conference was held on September 23-24, 2019, in Portorož, Slovenia. It was organized by the IEEE Slovenia Section together with Faculty of Electrical Engineering University of Ljubljana and other Slovenian professional societies. From the Laboratory for Open Systems and Networks, the researcher Samed Bajrić presented a research paper with the title “Reducing the number of solutions in the unit commitment problem using variations with repetition”, which is joint work with Izudin Softić, Nedžmija Demirović, Marina Pejić and Midhat Umihanić (all professors from Faculty of Electrical Engineering, University of Tuzla, BiH).
The book “Don Quihote in Slovenia or how Internet arrived in Slovenia”, written by prof. Borka Jerman Blažič and published by the Publishing Company e-Besede, provides very detailed information in narrative form about all scientific research that has contributed to the development of the computer networks, which are now known as the Internet and Internet services.
In the book, the basic components of the Internet are described in the context of the protocol stack war that took part in the eighties of the last century between the academics on both sides of the Atlantic Ocean. The long-lasting war delayed the development of the open computer systems and networks until 1991, when the Internet communication model, known as communication between the server and user device, emerged victorious. The book points to the advantages of the Internet communication model, among which are the intermediate devices that connect the Internet protocol stack with the underlying communication infrastructure composed from different technologies. In addition, the author points out that the Internet is a communication infrastructure without central governance, as the only central Internet infrastructure is composed from the hierarchical Domain Name Servers Infrastructure (DNS), which is the main glue that interconnect the Internet networks. The DNS infrastructure provides the mapping between the device numeric Internet address to the mnemonic name of the Internet components, for example “www.ijs.si”.
In the second part of the book, the author presents the events around Slovenia in the process of independence that coincided with the actions for setting up the first Internet network in the country and its inclusion in the world Internet. The book also contains 100 original documents from that time.
Members of the Laboratory for Open Systems and Networks from Jožef Stefan Institute organized a workshop in the scope of the GIRDA project on 4 July 2019 in Orehov Gaj. Along with our partners Simbioza Genezis, organization that cares for the inter-generation cooperation and learning, and the Slovenia philanthropy, we presented the results from the project. Girda is a project from the EU program Erasmus+, where the main objective is development of methodology for improving the digital literacy among elderly adults based on digital games and touch screen tablets. The development and the application of novel methods for acquiring digital skills was oriented around methods that successfully enable better coordination of the cognitive and motor skills of the elderly adults. This in turn facilitates efficient use of the modern digital devices, like smart phone, in everyday life of elderly people.
The Laboratory for Open Systems and Networks at Jozef Stefan Institute, together with 19 partners from 12 countries from Europe, America and Africa, marked the 25th anniversary of the ISABEL videoconferencing system. In the past, the system was used to carry out a number of large-scale distributed events with participants from all over the world. With the goal of participating in these events in 1997, the members of the laboratory also established the first broadband optical ATM connection of Slovenia with the rest of the world. Experience in mastering new technologies and the results of further research on networks and videoconferencing systems were used in several successful European Union projects, such as NICE, UNIVERSAL, PROLEARN and GLOBAL, and the establishment of our infrastructure group.
In May 2019 started with implementation the EU project funded within the program JUST-JCOO-AG-2018 entitled »European Investigation order – legal analysis and practical dilemmas of international cooperation – EIO-LAPD«. In the project partners come from Slovenia, Austria, Portugal, Italy, Germany and Croatia. The aim of the project is to study and to rise the awareness about the Directive about the European Investigation order. The laboratory tasks are connected to the problems of collecting e-evidence on digital devices.
