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)
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)

IEEEXtreme is an IEEE Student Activities Committee initiative to create a worldwide programming contest for IEEE Student Branches. The success of the past editions and the way IEEEXtreme is evolving, suggests that it will become the only worldwide competition capable of promoting the computer programming skills of collegiate students within a global(More)
Microgrid concept has been proven to have a positive impact on the operation of the power system. Distributed generation and energy storage enable control of microgrid power flow which can be optimized for participation in the electricity markets. This paper presents an optimization model for economical scheduling of a microgrid using linear programming.(More)
This paper proposes a coexistence model for two independent companies both operating hydropower plants in the same river flow, based on a case study of the Cetina river basin in Croatia. Companies are participants of the day-ahead electricity market. The incumbent company owns the existing hydropower plants and holds concessions for the water. The new(More)
Multi-terminal Direct Current Transmission (MTDC) is an emerging and promising technology for the transmission of electricity and the main initiator of the development of MTDC grids is offshore wind generation. However, prior to their construction, a thorough investigation of different aspects of their implementation and operation is required. In this(More)
In today’s liberalized and competitive power market, electric utilities, power producers and traders are exposed to increasing price risks and volatility. The growing reliance on renewable sources and their dependence on weather, nuclear uncertainty, market coupling and global financial instability are contributing to importance of accurate price forecast.(More)
