ABSTRACT – The power of neural networks in approximating continuous functions has led to more widespread use of this type of artificial intelligence in the field of time-series forecasting. This work examines the efficiency oftime-series prediction models when given the dataset of hourly values connected to day-ahead market of electrical energy. It presents the processing and windowing of the data to fit the prediction models, describes the specifics of the day-ahead market of electrical energy and more closely describes the way each of the used neural network models works.
The work looks at created neural network models with dense layers, convolutional neural networks (CNN) and recurrent neural networks (LSTM), and measures their performance. Testing results show their accuracy when predicting based on the dataset of hourly values of day-ahead electricity on the HUPX market, coupled with the hourly weather data, as well as the related dataset of the hourly values of electricity consumption in Montenegro.

H2020 AIMHiGH project featured in the Worhshop on Digitalization in Agriculture and Food Supply Chain

H2020 AIMHiGH – FoodHub Centre of Excellence and Faculty for Information Systems and Technologies at the University of Donja Gorica organized a workshop on Digitalization in Agriculture and Food Supply Chain. This was an online event managed through Moodle LMS platform during Octobar 7-15, 2021. There was over 50 attendees, mainly students and faculty members, but also some representatives from the industry. The organization of the event was done in the context of DIPOL project sponsored by the Ministry of Science of Montenegro. UDG and DNET were responsible for the realization of the event. H2020 AIMHiGH project done as an experiment within the FF4EuroHPC project was presented by Mr. Stevan Cakic.

UDG / EuroCC Montenegro will take part at the IEEE IDAACS 2021 conference

UDG researchers will be presenting the paper titled “Forecasting Day-Ahead Electricity Price with Artificial Neural Networks: a Comparison of Architectures”, authored by M. Pavicevic and T. Popovic, at the upcoming IEEE IDAACS 2021 conference. The conference will be taking place on 22-25 September 2021. The paper presents the use of AI/ML algorithms and CNN architectures for prediction of prices for the electric energy markets. More info on the conference is available at the following link.

ABSTRACT – The spot price prediction for the electric energy markets is a widely approached problem, used by many participants in the market. The ever-shifting rules and regulations, rising percentage of the electricity on the market being produced by solar and wind plants and many stochastic factors influencing it make the market price of electricity very volatile and hard to forecast. Many methods are used to tackle this problem, and their efficiency varies from dataset to dataset. In this work, we use the dataset of hourly day-ahead spot prices from the Hungarian HUPX market, and couple it with weather data for Hungary. We test various types of Dense, Recurrent and Convolutional neural network architectures and report on the results.

Cooperation between CoE FoodHub and HPC NCC Montenegro

Cooperation between Centre of Excellence, FoodHub and HPC NCC Montenegro was initiated due to the possibility of overlapping a significant number of activities in the field of digitization and computer simulations. Main purpose of cooperation is finding several software solutions that would greatly improve food safety, public health and food business.

Collaboration between FoodHub/CoE and EuroCC (HPC NCC Montenegro)

Thanks to the program and support of the European Food Safety Authority (EFSA), the Faculty of Food Technology, Food Safety and Ecology in cooperation with the Directorate for Food Safety, Veterinary and Phytosanitary Affairs, implemented the project “Support to National Dietary Surveys in Compliance with the EU Menu methodology (sixth support) – “The adults’ survey”, including subjects from 10 to 74 years old ”, which is the largest study on eating habits of the population of Montenegro. The possibility of applying IT solutions is based on the fact of generating a large number of important data from this project. Data from this project could be of great importance for the development of software solutions for risk assessment in the field of food safety.

Considering the importance of the HACCP system and the long period of time required for its implementation, the meetings also discussed the development or improvement of software that would greatly simplify and speed up this process, which would make great progress in the business of food businesses and to the entire food safety system.

UDG researchers will be presenting a paper at IEEE IcETRAN 2021 Conference

Members of our EuroCC Montenegro team will be presenting the paper titled “Combined adaptive load balancing algorithm for parallel applications”, authored by L. Filipovic, B. Krstajic, and T. Popovic, at the upcoming IcETRAN 2021 conference. The conference will be taking place on Sep 8-10, 2021. More info on the conference is available at the following link.

ABSTRACT – Development and improvement of efficient techniques for parallel task scheduling on multiple cores processors is one of the key issues encountered in parallel and distributed computer systems. The purpose of process distribution improvement in parallel applications is in increased system performance, reduced application execution time, reduced losses and increased resource utilization.

This paper presents combined adaptive load balancing algorithm based on domain decomposition and master-slave
algorithms and its core scheduling adaptive mechanism that handles load redistribution according obtained and analyzed data. Selection of distribution algorithm, based on collected parameters and previously defined conditions, proved to deliver increased performances and reduced imbalance. Results of simulations confirm better performance of proposed algorithms compared to the standard algorithms reviewed in this paper.
