An expert system approach to unit commitment problem
(1993)This paper describes a hybrid expert system dynamic programming approach to the power system unit commitment problem. Here the scheduling output of the usual dynamic programming is enhanced by supplementing it with the ... 
Extraction of Assam coal through stepwise alkali treatment under ambient pressure conditions
(1995)A process for the stepwise alkali treatment of coal under mild conditions using phenol as a solvent has been developed. About 70% of Assam coal was rendered extractable through three alkali treatment steps in hot phenol ... 
Extraction of Coals Through Alkaline Degradation at Plastic State Under Ambient Pressure Conditions
(1995)A new technique to degrade bituminous coals and lignites using alkali in liquid paraffin at the plastic state of coals has been developed. More than 60% of coal can be rendered extractable. The technique is very simple and ... 
Fast valving scheme using parallel valves for transient stability improvement
(1999)A new fast valving scheme of steam turbines using two parallel valves for improving the transient stability of a power system is proposed. The influence of the actuation time parameters of a conventional fast valving scheme ... 
Feasibility and design studies for heat recovery from a refrigeration system with a canopus heat exchanger
(1995)This paper presents an investigation of the feasibility of heat recovery from the condenser of a vapour compression refrigeration (VCR) system through a Canopus heat exchanger (CHE) between the compressor and condenser ... 
Feasibility study of solar distillation plants in south pacific countries
(1991)Most South Pacific countries are located near the equator. Thus a sufficient amount of solar energy is available. The South Pacific countries consist of various small mountainous islands. In the present study, a review of ... 
Feed optimization for the slotted line antenna for highdensity plasma production
(1990)nvestigations on the optimization of feed structures for exciting the slotted line antenna for highdensity plasma production are presented. Each feed structure used (except the direct feed) excites a preferred component ... 
Financial evaluation of SPV lanterns for rural lighting in India
(1996)Financial evaluation of solar photovoltaic (SPV) lanterns has been undertaken. The factors influencing the capital as well as the maintenance cost of SPV lantern have been analyzed. Cost per hour of illumination and cost ... 
Financial feasibility analysis of boxtype solar cookers in india
(1996)A framework for financial evaluation of a boxtype solar cooker, using cost functions for its capital cost, has been developed. The annual benefits accrued to the user are quantified in terms of number of meals cooked per ...

Frequency blueshift during laserinduced breakdown of dielectrics
(2004)y form only given. A phenomenological model of frequency blueshift during laser breakdown of dielectrics by ultrafast pulses is developed. The time scale is too short for heat conduction and diffusion consequently interaction ... 
Frequency up shift of a high intense laser pulse in a gas filled capillary plasma
(2004)Summary form only given. A high intensity laser pulse propagates through the H2gas filled capillary discharge waveguide with parabolic radial electron density profile. The capillary comprises of alumina tube. Laser causes ... 
Fundamentals and characteristics of solar radiation
(1993)The calculation of solar radiation received at a particular place and at a particular time, involves many factors like rotation and revolution of the earth, atmospheric attenuations, atmospheric conditions, time of day and ... 
Fuzzy decision making in multiobjective longterm scheduling of hydrothermal system
(2001)In the paper, a fuzzy decision making methodology is presented to decide the generation schedule of longterm hydrothermal problems with explicit recognition of statistical uncertainties in system production cost data, NOx ... 
Fuzzy supervisory controller for improved voltage dynamics in power factor corrected converter
