The asymmetric unit of the title compound, C(7)H(7)BrIN, contains two independent mol-ecules, which are linked by weak N-H⋯N hydro-den-bonding inter-actions between the amino groups.

In this paper, the performance of A1515 centrifugal pump was studied on a high parameters and precision large general test platform in combination with Huang-jin-xia hydro-junction Hanjiang-to-Weihe River valley water diversion project. The efficiency characteristics cavitation were tested measured respectively. All collected recorded through acquisition system. experimental results show that o...

This paper presents a mixed-integer linear programming (MILP) formulation for sizing and siting of battery energy storage systems (BESSs). The problem seeks to minimize both operation costs BESS investment. proposed model includes restrictions the conventional security-constrained unit commitment problem, piece-wise approximation power losses, hydro generation units. is tested in 6-bus test sys...

Hydrology does not yet possess a generally agreed upon catchment classification system. Such a classification framework should provide a mapping of landscape form and hydro-climatic conditions on catchment function (including partition, storage, and release of water), while explicitly accounting for uncertainty and for variability at multiple temporal and spatial scales. This framework would pr...

The aim of the investigation is to develop a control method of a rotary blood pump (RBP) to solve the following problems: estimation of the pump flow rate, achievement and maintaining of the desired flow level through the continuous adjustment of pump speed and prevention of adverse effects on the cardiovascular system. Results. Functional chart of RBP control consists of several units: a unit ...

Hydro-electric power utilities convert the potential energy of water to electricity through the operation of generation turbines. Each turbine unit has an operating range and incurs a fixed start-up cost. The problem of determining which turbines should be operating at any point during the day whilst ensuring that the demand for electricity is satisfied is known as the unit commitment problem. ...

The evaluation of hydraulic constants is generally one of the main components of reservoir engineering projects such as the development of radioactive waste disposal sites or the construction of underground CO2 storage. In the example presented here, flow pump experiments were conducted for the Horonobe mudstone to evaluate specific storage and hydraulic conductivity. The flow pump experiments ...

The short term cost optimal dispatch of electric power in a generation sys tem under uncertain electricity demand is considered The system comprises thermal and pumped storage hydro units An operation model is developed which represents a multistage mixed integer stochastic program and a conceptual solution method using La grangian relaxation is sketched For xed start up and shut down decisions...

Indonesia has vast solar energy potential, far more than needed to meet all its requirements without the use of fossil fuels. This remains true after per capita consumption rises match developed countries, and most functions are electrified minimize Because relatively small potential from hydro, wind, biomass, geothermal ocean energy, it will rely mostly on for sustainable needs. Thus, require ...
