For modern synthetic aperture radar (SAR), it has much more urgent demands on ground moving target indication (GMTI), which includes not only the point moving targets like cars, truck or tanks but also the distributed moving targets like river or ocean surfaces. Among the existing GMTI methods, displaced phase center antenna (DPCA) can effectively cancel the strong ground clutter and has been w...

A hoist controlled by a computer is widely used for moving electroplates which is chemically treated in a sequence of tanks. The hoist scheduling directly a.ects the throughput of a production system. The objective of the hoist scheduling problem is to schedule the moves to maximize the throughput. This paper investigates the hoist scheduling problem, a speci2c material handling issue, in a man...

We evaluated the consumption of duckweed (Lemna minor, Linnaeus) by juvenile Blue Tilapia (Oreochromis aureus, Steindachner) through 48 hour indoor tank feeding trials. Feeding trials consisted of 5 tanks (4 treatment, 1 control). Tanks were stocked with 25 g of fresh duckweed at the initiation of each feeding trial. Designated treatment tanks were also stocked with 1 tilapia per tank. At the e...

Nineteen representative water samples were collected from surface and ground water sources, covering urban, rural area, shallow and deep aquifers in Pondicherry region. The samples were analysed for various pesticide residues such as HCH, Aldrin and DDT. Both surface and ground water sources found to exhibit the residuals of various pesticides. The residual levels oforganochlorine pesticides we...

Planktivorous fish which limit zooplankton grazing have been predicted to increase algal biodiesel production in wastewater fed open reactors. In addition, tanks with higher algal diversity have been predicted to be more stable, more productive, and to more fully remove nutrients from wastewater. To test these predictions, we conducted a 14-week experiment in Houston, TX using twelve 2,270-L op...

The objective of this study was to compare the presence on goats and cattle of adult ticks that usually infest cattle. To this end ticks collected from sets of five goats were compared with those collected from sets of five cattle at 72 communal dip-tanks in the eastern region of the Eastern Cape Province. Amblyomma hebraeum was present on goats at 25 and on cattle at 39 dip-tanks, and a total ...

cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. usually failure of cylindrical tanks leads to serious consequences. during the past earthquakes such as 1964 alaska and 1999 turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. therefore, evaluation of seismic performance of these str...
