In the last 30 years the Chinese Aquaculture Sector has become one of the most rapidly developing areas within Chinese Agriculture. The total output of aquaculture products (more than 51 million tons) has placed China as the world’s largest producer of aquaculture products since 1990, with more than 70% of...
Japan has been the biggest export market of aquatic products of China for many years. The export of aquatic products to Japan reached more than 700,000 ton and $ 3 billion in 2007. The influence to the export market caused by the sweeping economic crisis will affect the benefits of...
This paper is intended to perform cost-benefit, break-even and sensibility analysis of higher-place pond culture of Penaeus vannamei through a case study of a farmer in Zhanjiang City of Guangdong Province, using cost-benefit data about this farmer’s higher-place pond culture of Penaeus vannamei collected from field survey. Major findings of...
Graphical models use Markov properties to establish associations among dependent variables. To estimate spatial correlation and other parameters in graphical models, the conditional independences and joint probability distribution of the graph need to be specified. We can rely on Gaussian multivariate models to derive the joint distribution when all the...
The purpose of this study was to determine the
effects of frequent versus conventional testing on
Chemistry achievement test anxiety, and attitudes toward
science of students enrolled in general chemistry classes
at the University Technology of Malaysia. The subjects
consisted of 278 students taking first year Chemistry at
the University...
Sensing is a significant engineering science which quantify parameters from the physical world and discover the physics running behind the measurement process. Optical sensing makes use of electromagnetic waves from infrared to ultraviolet on the light spectrum as a medium to measure variables, such as position, temperature and strain. Image...
In a recent paper, Sandwell and Agreen [1984; hereafter SA]
presented figures of global seasonal wind speed and sea state
as measured by the GEOS 3 satellite altimeter. Since that
time, Chelton and McCabe [1985; hereafter CM] have found
that problems exist in the algorithms used to retrieve wind
speed...
