The paper presents an analysis of a one-semester technical course " Electrical facilities ". The goal of the paper is to show how a system of real-time knowledge testing at undergraduate level, using a radio-frequency clicker system and conventional knowledge assessment methods, was implemented on a single course at the University of Zagreb.

Accurate forecasting tools are essential in the operation of electric power systems, especially in deregulated electricity markets. Electricity price forecasting is necessary for all market participants to optimize their portfolios. In this paper we propose a hybrid method approach for short-term hourly electricity price forecasting. The paper combines(More)
—Water is scarce resource with uncertain availability. Hence finding an optimal production schedule for hydro producer is usually a complex task and it is necessary to carefully balance the timing of water use. This paper addresses the self-scheduling problem for a price-taker hydro producer. The goal is maximizing the profit of a hydro producer through(More)
Placement of the acetabular cup during total hip arthroplasty is of great importance because usually every deviation from the ideal centre of rotation negatively influences endoprosthesis survival, polyethylene wear and hip load. Here we present hip load change in respect to various acetabular cup positions in female patients who underwent total hip(More)
This paper analyzes a price-taker hydro generating company which participates simultaneously in day-ahead energy and ancillary services markets. An approach for deriving marginal cost curves for energy and ancillary services is proposed, taking into consideration price uncertainty and opportunity cost of water, which can later be used to determine hourly(More)
This paper presents a small electricity market study based on an agent-based power network simulator in deregulated conditions. A simple six node network is modelled in EMCAS to observe effects of transmission line outages and transmission congestion problems. The effects of price variations due to line outages are presented and discussed. Possible economic(More)
