One of the most striking differences between any Lisp dialect and C++ is not the obvious syntax differences, but rather their opposing views on management of objects with indefinite extent. While Lisp systems automatically recover storage used by objects that are no longer needed by the program, C++ requires that the user explicitly delete the object in order to reclaim storage. Automatically m...

self-compacting concrete (scc) is a highly fluid yet stable concrete that can flow consistently under its own weight, pass between bars, and fill in formwork without the need of compaction. the application of scc effectively resolves the difficulties of concreting in situations with complicated formwork and congested reinforcements. in this paper, the bond between scc and steel reinforcement wa...

A monitoring architecture and corresponding data model to support fault diagnosis in distributed automation systems is presented. The monitor system consists of a central monitor and a set of the monitoring agents, that cooperate via rule sets and diagnosis results. The data model combines event-based and continuous diagnostic methods and allows to adjust the monitor overhead. The achieved comp...

TV commercials recognition is a need for advertisers in order to check the fulfillment of their contracts with TV stations. In this paper we present an approach to this problem based on compacting a representative frame of each shot by a PCA of its color histogram. We also present a new algorithm for scene break detection based on the analysis of local color variations in consecutive frames of ...

In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...
