TEP, the Hungarian Technology Foresight Programme, was launched in 1997, as the first one in Central and Eastern Europe, to provide inputs to a national strategy by identifying socio-economic challenges and developing broad visions for the future. Specifically, it was aimed at analysing Hungary’s current strengths and weaknesses, developing scenarios (visions) and formulating policy proposals t...

This work analyses the application of heuristic algorithms in the transmission network expansion planning problem using the Hybrid Linear Model (HLM). The HLM is a relaxed model which still has not been fully explored. The work presents a detailed study of a constructive heuristic algorithm for the HLM and proposes an extension of the model and a solution technique for multi-stage planning. Qua...

In planning studies, the conventional approach for steady state contingency analysis is to test all contingencies sequentially for evaluating system performance and reliability. This analysis consists of simulating outages of one or more generating units and transmission lines to study their effects on bus voltage, generator MVAR outputs and line power flows. But new challenges and uncertaintie...

OBJECTIVES/HYPOTHESIS To describe the speech rehabilitation outcomes of patients undergoing total laryngectomy (TL) in the 21st century. STUDY DESIGN Retrospective chart review. SETTING Tertiary academic center SUBJECTS AND METHODS Retrospective review of 167 patients who underwent TL from June 2000 to February 2012. Demographics, disease variables, and surgical factors were reviewed. Pri...

In this paper, a novel framework is proposed to study impacts of regulatory incentive on distributed generation (DG) investment in sub-transmission substations, as well as upgrading of upstream transmission substations. Both conventional and wind power technologies are considered here. Investment incentives are fuel cost, firm contracts, capacity payment and investment subsidy relating to wind ...

in recent years, significant research efforts have been devoted to the optimal planning of power systems. substation expansion planning (sep) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. the large number of design variables, and combination of discrete ...

Numerous membrane fouling studies have been conducted to predict and prevent membrane fouling. It was only recently that a new parameter, TEP, was introduced in this research. The deposition of TEP on reverse osmosis (RO) membranes has already been imaged, correlations between ultrafiltration (UF) fouling and TEP concentrations have been reported. Furthermore, TEP deposition takes place in an e...

Although significant private investment is absorbed in different sectors of power systems, transmission sector is still suffering from appropriate private investment. This is because of the pricing policies of transmission services, tariffs, and especially for investment risks. Investment risks are due to the uncertain behaviour of power systems that discourage investors to invest in the transm...
