The purpose of this study was to look into teachers' perceptions of code-switching functions and effects in English as a foreign language classroom. In the study, a descriptive survey design and an interview were used to investigate the functions and effects of code-switching in English as a foreign language (EFL) classroom. 46 people responded to the survey questionnaire about code-switching functions and their impact in the classroom. Seven teachers participated in the group interview. The in...

Efficient resource planning is recognized as one of the key enablers making the large-scale deployment of next-generation wireless networks available for mass usage. Modelling, planning, and software simulation tools reduce both the time needed and costs of their tuning and realization. In this paper, we propose a model-driven framework for proactive network planning relying on synergy of deep learning and multiobjective optimization. The predictions about service demand and energy consumption ...

Nenad Petrovic / Issam Al-Azzoni

Vaccination is recognized as one of crucial measures in battle against COVID-19, contributing to both the reduction of its negative impact on infected person and overall spread reduction. In this paper, we focus on adoption of model-driven approach to proactive and cost-effective vaccine distribution, relying on deep-learning (for vaccine-demand predictions) and multi-objective optimization (for solving the allocation problem). As outcome, software simulation tool for efficient vaccination plan...
