The countries participating in the mathematics portion of the TIMSS 1999 Video Study included Australia, the Czech Republic, Hong Kong SAR,1 Japan, the Netherlands, Switzerland, and the United States. The TIMSS 1995 and 1999 average mathematics scores for these countries are displayed in table 1. On the TIMSS 1995 mathematics assessment, eighth-graders as a group in Japan and Hong Kong SAR were...

introduction: european foundation for quality management has designed the efqm model to determine the rate of organization development and excellence and construct ways to achieve organizational excellence. this model is used to compare the current situation of each organization with an ideal organization. the aim of this study was to determine the performance self-assessment scores in selected...

NAPAP 1996 Assessment http://www.nnic.noaa.gov/CENR/NAPAP/NAPAP_96.htm (1 of 7) [6/8/2002 10:56:42 AM]

The global availability of synthetic aperture radar (SAR) wave mode data from the European Remote Sensing (ERS) satellites ERS-1 and ERS-2, as well as ENVISAT, allows for the investigation of the wind field over the ocean on a global and continuous basis. For this purpose, 27 days of ERS-2 SAR wave mode data were processed, representing a total of 34 310 imagettes of size 10 km 5 km, available ...

Land salinization is threatened with secondary salinization recently because of unreasonable exploitation of natural resources and global change. However, previous assessments cannot obtain comprehensive and spatial explicit statistics and impede to develop ecologically sound policies for government. This study tries to confront these difficulties and identify key anthropogenic determinants, th...

a methodology of soil moisture assessment around a levee based on a backpropagation neural network and using Synthetic Aperture Radar (SAR) data is developed. Soil moisture changes along a levee over a period of time can help to monitor and find potential failure indicators such as slides and sand boils around the levee. Several analytical and empirical models have shown relationships between S...

BACKGROUND The assessment of electromagnetic field distribution near radiophones and their use warranted an analysis of ther mal exposure hazards and related health effects, based on i.e. numerical calculations of specific energy absorption rate (SAR). MATERIALS AND METHODS The investigation concerned radiophones of conventional and trunked communication systems. Electromagnetic hazards asses...

We present an evaluation of the impact of a recently proposed synthetic aperture radar (SAR) imaging technique on feature enhancement and automatic target recognition (ATR) performance. This image formation technique is based on non-quadratic optimization, and the images it produces appear to exhibit enhanced features. In the first part of this paper, we quantify such feature enhancement throug...
