1 In August 2003, while many Europeans were heading to the beaches to mitigate the effects of the worst heat wave on record, José Eduardo Sampaio, the CEO of Casa XXI, was faced with another kind of heat. Cartão 21, the innovative payment system of Casa XXI that he had personally conceived and subcontracted, had dramatically failed on August 6 th during the high-visibility inauguration of Alval...

The travel patterns of senior citizens in Seoul were analyzed using Automatic Fare Collection (AFC) data. The focus was specifically on mode choices and transfer patterns. The results showed that 99% of trips made by senior citizens (individuals over 65 years old), who were given free subway transit passes, consisted of single-mode trips. The average travel time was 31 minutes, and subway trave...

Any of views is formally defined within description logics that were established as a family of logics for modeling complex hereditary structures and have a suitable expressive power. This paper considers the Application Development Environment (ADE) over generalized variable concepts that are used to build database applications involving the supporting views. The front-end user interacts the d...

Mycotoxins are toxic fungal metabolites that cause intoxication when consumed by animals, including humans. Fungi that produce mycotoxins are called toxigenic fungi. The toxigenic fungi do not produce mycotoxins after they have been ingested by animals and humans. Toxigenic fungi grow in corn, cereals, soybeans, sorghum, peanuts, silage and other food, feed crops or hay in the field, and in gra...

In this paper we present an abstract execution model for active networking that blends the notions of universal computing device and network router. Pivotal element of this architecture is a generalized route table that stores forwarding data as well as program instructions. The route table corresponds to the memory module of a von Neumann computer, but in contrast to the classic “stored progra...

The benign environment and long confinement times obtained with ion storage techniques have led to some unique experiments in the area of precision measurements and fundamental constants. This is perhaps epitomized by the single electron g factor measurements at the University of Washington in which a precision of 4 parts in 10” has been attained. Now, use of lasers to cool stored ions has allo...

abstract during these protracted years, mankind’s main foods consist of grains-specially wheat, oats and rice. granary production and its storage have been one of the main concerns of a human being for a long time. microwave radiation as a safe insect control agent could secure high mortality rate of insect population by increasing the temperature of insects’ body and its niche. low temperature...

The universally applied Codd's relational model has two constructs: a stored relation, with stored attributes only and a view, only with the inherited ones. In 1992, we have proposed third construct, mixing both types of attributes. Examples showed the idea attractive. No one followed however. We now revisit our proposal. We show that a relational database scheme using also our construct may be...
