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 selfscheduling problem for a price-taker hydro producer. The goal is maximizing the profit of a hydro producer through participating in the day-ahead energy and a...

In hydro power plants from Romania, there is a major interest for the implementation of digital systems for monitoring and control to replace the conventional control systems for power, frequency and voltage. Therefore is necessary to develop mathematical models capable to accurately describe both dynamic and stationary behaviour of the hydro units, in order to be able to implement digital cont...

The choice of hydraulic turbine manufacturer and their performance assessment are becoming major challenges. Evaluating product criterion and selecting optimum manufacturer are complicated tasks due to the fact that various criteria or objectives must be considered in the decision making process having various importance. In this study, we proposed a hydro turbine manufacturer selection analysi...

The title compound α-ammonium iron(III) bis-[hydro-gen arsenate(V)], α-NH4Fe(HAsO4)2 (or poly[ammonium bis-(μ-hydro-gen arsenato)ferrate(III)], {NH4[Fe(HAsO4)2]} n ), syn-the-sized hydro-thermally, is isostructural with NH4Fe(HPO4)2. Condensation of the hydro-gen arsenate groups with FeO6 coordination octa-hedra via common corners results in an overall three-dimensional framework containing int...

This paper describes a software tool called Hydro Planner, being developed as part of CSIRO’s Water for a Healthy Country National Research Flagship Program. The main purpose of Hydro Planner is to enable urban water planners and managers to adopt a systems approach to obtain an improved understanding of how water, wastewater and stormwater systems interact with each other and with natural wate...

The attenuation of engine vibration transmitted to a chassis has been a major focus in the automotive community for the increase of comfort for the driver and passengers. A hydro-mount system is designed to reduce the transmission of engine vibration to the chassis. It is also used for supporting the static load by an engine weight. In this paper, we present a modeling and parameter estimation ...

In the title compound, the de-hydro-dipeptide (Boc-Phe-ΔAla-OiPr, C20H28N2O5), the mol-ecule has a trans conformation of the N-methyl-amide group. The geometry of the de-hydro-alanine moiety is to some extent different from those usually found in simple peptides, indicating conjugation between the H2C=C group and the peptide bond. The bond angles around de-hydro-alanine have unusually high valu...

BACKGROUND One of the considerable uses of lettuce (Lactuca sativa) seed in traditional medicine has been to reduce semen, sperm and sexuality. OBJECTIVE The aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis. MATERIALS AND METHODS In this experimental study 24 adult male NMRI mice weighing 20-25...

Transition from fossil fuels to renewable sources is inevitable. In this direction, variation and intermittency of renewables can be integrated into the grid by means of hybrid systems which operate as a combination of alternative resources, energy storage and long distance transmission lines. In this study, we propose a two-stage stochastic mixed-integer programming model for sizing an integra...
