This work presents our first steps in developing a Global Real-time Infectious Disease Surveillance System (GRIDDS) employing robust and novel infectious disease epidemiology models with real-time inference and pre/exercise planning capabilities for Lahore, Pakistan. The objective of this work is to address the infectious disease surveillance challenges (specific to developing countries such as...
The European Groundwater Directive could be improved by limiting the scopes of the Annexes I and II to the manmade and natural substances, respectively, and by defining a common monitoring protocol. The changes in the European landuse patterns, in particular the urban sprawl phenomena, obscure the distinction between the point and diffuse sources of contamination. In the future more importance ...
Porous materials are found in natural structures such as wood, bone, coral, cork and sponge and are synonymous with strong and lightweight structures. It is not surprising that manmade porous materials have followed and those made from polymers and ceramics have been widely exploited. The commercialisation of porous metals has lagged somewhat behind, but has received a boost following a surge i...
This paper presents an application of perceptual grouping rules for content-based image retrieval. The semantic interrelationships between different primitive image features are exploited by perceptual grouping to detect the presence of manmade structures. A methodology based on these principles in a Bayesian framework for the retrieval of building images, and the results obtained are presented...
296-220 Abstract In this paper we present a study of the comparison of the performance of content-based image retrieval systems based on structure [1] with those based on histogram and texture analysis methods, where retrieval is concerned with locating images containing manmade objects. The advantage of using structure in such queries is demonstrated by analyzing an image database containing m...

Aquatic field studies were conducted in Tha Mai District, Chanthaburi Province, Thailand. Larval habitats of Anopheles dirus were examined from November 1986 through June 1988 in 42 manmade gem pits. Larvae were found in pits containing clear water under full or partial shade. The abundance of different kinds of mosquito larvae were related to seasonal changes in these aquatic habitats. Variati...
Aid to families with dependent children (AFDC) began with the Social Security Act, passed 50 years ago to provide what President Franklin D. Roosevelt called a “safeguard against misfortunes which cannot be wholly eliminated in this manmade world of ours. ” In creating the program, originally called aid to dependent children, the .Federal Government for the first time accepted responsibility fo...
