the study examines production efficiency of farmers under national fadama-ii project in oyo state nigeria. primary data were collected from two hundred and sixty-four farmers using multistage sampling technique. the analytical framework used for the study include: descriptive, infrastructure index, gross margin and stochastic frontier production function. average infrastructural index in the ar...

abstract the main aim of the paper is to determine the marketing efficiency of poultry industry in karaj. in this research the marketing margin and the marketing efficiency of poultry market in different level of the market in karaj was calculated. the results showed that slaughter houses gain the main part of marketing margin and marking profit. the share of slaughter house was more that 50 pe...

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...

Current statistical models for structured prediction make simplifying assumptions about the underlying output graph structure, such as assuming a low-order Markov chain, because exact inference becomes intractable as the tree-width of the underlying graph increases. Approximate inference algorithms, on the other hand, force one to trade off representational power with computational efficiency. ...

Recently, the use of wind farm in power systems is increasing rapidly it having a more noticeable impact on manner which these operate. When large farms are connected to system network, voltage stability concern as affects operation. This paper investigates location network when reactive limitation generators taken into consideration and reaches its maximum loading. An IEEE-14 bus test was modi...

There is a great deal of interest in continuous beds as stationary phases for both HPLC and CEC. There are various ways to prepare monoliths, by polymerization of organic species or by polymerization of silicon alkoxides. The former method has recently been reviewed, while silica based monoliths are now commercially available. The purpose of this paper is to deal with the problems associated wi...

The Flexible AC Transmission System (FACTS) in a Power System improves stability, reduces the cost of generation, losses and also improves loadability of the system. In order to use FACTS devices in a Power system to maximum extent, optimal location of FACTS devices is an important consideration. This paper presents the optimal location of series FACTS device for eliminating or minimizing the l...
