2011 – 2014: Advanced modeling and simulation of liquid-solid process

B. Filipič, T. Tušar, M. Mlakar

The goal of this research project was to enhance the physical modeling capabilities and development of numerical methods for liquid-solid processes. Our participation in the project was focused on optimization of the alloy solidification process where the task is to determine process parameters such that the required structure of the material is obtained in the shortest possible time. Using an evolutionary multiobjective algorithm coupled with a process simulator, we minimized the concentration and structural inhomogeneities in the solidifying material and the duration of the solidification process by influencing the cooling process dynamics. Dealing with this problem was a source of motivation for our work on improving the multiobjective optimization methodology by involving surrogate models and visualizing the results, while the produced results are of practical importance for metallurgical production. The project was funded by the Slovenian Research Agency.

2010 – 2014: Simulation and optimization of casting, rolling and heat treatment processes for competitive production of topmost steels

B. Filipič, T. Tušar, M. Mlakar

Funded by the Slovenian Research Agency and co-funded by the Štore Steel company, this project was dealing with multiscale through-process modeling of the steel production sequence consisting of continuous casting, rolling, and heat treatment. Our role in the project was to formulate and provide a tool for solving the problem of tuning the process parameter settings for continuous casting to result in the highest possible quality of cast steel. We designed and implemented a program that accepts boundary constraints and discretization steps of the considered process parameters, and boundary constraints and target values of the selected metallurgical criteria as input. Since the criteria are conflicting, the program returns a set of trade-off solutions according to the principles of multiobjective optimization and displays them in parallel coordinates. Optimization is carried out using the DEMO (Differential Evolution for Multiobjective Optimization) algorithm, and the solutions are evaluated via an external numerical simulator of the casting process. The program is in use in the Štore Steel company.

2012 – 2013: e-Turist – The easiest way to plan your perfect trip

M. Luštrek, B. Kaluža, B. Cvetković, H. Gjoreski

E-Turist is a mobile application that will attempt to provide a tourist with an experience comparable to that offered by a professional tour guide, but tailored specifically to him/her. The tourist will enter his interests, the available time and any special requirements he/she may have. Based on these, the application prepares a personalized sightseeing program using a recommender system. Afterwards, the application guides the tourist using the GPS, providing a multilingual description accompanied by photos. The description will be available on the mobile phone screen and via synthesized voice. The tourist may comment and rate each sight, which is then used by the recommendar system and tourism workers to improve their services. The mobile application is accmpanied by a web application through which tourism workers may enter information on sights of interest and track the activity of their visitors.

2010 – 2013: EUSAS – European Urban Simulation for Asymmetric Scenarios

A. Tavčar, D. Kužnar, E. Dovgan, V. Mirchevska, B. Mahnič

The main objective of the EUSAS project is to develop methods for multi-agent modeling of asymetric conflicts. The aim is to develop a new approach to mission analysis and training for low level units facing asymmetric threats in an urban environment. Our task is to discover the common agent strategy by knowing only low-level agent behaviour and basic domain knowledge. Moreover, the objective is to transfer some of the observed behaviour patterns into highly realistic and reusable models of human behaviour in riots. The constructed models will be later used in simulations to provide a more realistic behaviour for training peace-keeping personnel.

2010 – 2013: MIRABEL – Micro-Request-Based Aggregation, Forecasting and Scheduling of Energy Demand, Supply and Distribution

B. Filipič, T. Tušar, E. Dovgan

Supported by the European Commission’s Seventh Framework Programme (FP7), this project was aimed at developing a conceptual and infrastructual approach that allows energy distribution companies to efficiently manage higher amounts of renewable energy and balance energy supply and demand. Specifically, we worked on a concept of micro-requests with time shifts to handle the demand and supply of energy on a household level. Further, we defined methods to predict the energy supply and demand in the small (i.e., for households) and in the large and to update predictions over time. We aggregated (and disaggregated) the micro-requests on a regional level, and we developed a scheduling approach for energy production and consumption based on aggregated requests.

2004 – 2006: Alvis – Superpeer Semantic Search Engine

M. Gams, V. Vidulin, M. Luštrek, A. Pivk

ALVIS was FP6 STREP project that conducted research in the design, use and interoperability of topic-specific search engines with the goal to develop an open source prototype of a distributed, semantic-based search engine. Our role in the project was to develop a prototype of genre classifier, which classifies web pages into categories such as, e.g., blog, frequently asked questions, shopping. The classifier was implemented in the search engine, where it enabled the user to search the pages not only by specifying their content (e.g., with the keyword “iPhone”), but also by specifying their genres (e.g., by specifying genre “shopping”, pages with reviews and subjective comments are excluded). In this manner, the engine returns a set of pages that are closer to user’s interests than the pages returned by the keyword-based search engines.

2004 – 2006: WINDECT – Wireless Local Area Network with Integration of Professional-Quality DECT Telephony

M. Špegel, P. Reinhardt, R. Blatnik

WINDECT is a novel approach to merge wireless networks by integrating professional quality telephony into WLANs to get high quality “voice over WLAN”. The result is an innovative application in the field of wireless and mobile communications. Our contribution in the project was development and construction of a research test-bed for metricsbased testing of the quality of voice communication in VoWLAN/VoIP communications. The measurements using this test-bed have provided determination of PESQ MOS, delay, jitter and packet loss derived from the analysis of analogue voice signal as well as voice packet streams. A handover tests were also performed by emulation of mobile phone’s roaming using hand attenuation of RF signals in so called »open air« from involved two access points. In the final phase of the project the test-bed was used for the performance evaluation of WINDECT-enabled mobile phones and access points in the form of demonstrator environment. The results confirm the advanages of the WINDECT approach over standard VoIP/WLAN solutions are achievable in practice. Here is the web site of the project.
