The performance of schools in a large urban school district was examined using achievement data from a longitudinally matched cohort of middle school students. Schools were evaluated in terms of the mean achievement and mean growth of students in mathematics and language arts. Application of multilevel, longitudinal models to student achievement data revealed that 1) school performance varied a...

This article describes some preliminary work done by the National Centre for Classification in Health (NCCH) in response to the recommendations of the General Practice Coding Jury.

In this paper we introduce four Z 2 topological indices ␨ k =0,1 at k = ͑0,0͒, ͑0,␲͒, ͑␲ ,0͒, and ͑␲ , ␲͒ characterizing 16...

The optimization of 45nm NMOS device was studied using Taguchi Method. This method was used to analyze the experimental data in order to get the optimum results. In this paper, there are four factors were varied for 3 levels to perform 9 experiments. Silicide on the poly-Si gate electrode was used to reduce the gate electrode resistance. The virtually fabrication of 45nm NMOS device was perform...

This paper presents the results obtained by our group at the GeoCLEF 2006. Our system used a method based on the expansion of

We perform a linguistic analysis of documents during indexing for information retrieval. By eliminating index terms that occur only in subordinate clauses, index size is reduced by approximately 30% without adversely affecting precision or recall. These results hold for two corpora: a sample of the world wide web and an electronic encyclopedia.

The problem of information overload is hot issue with growth of worldwide web. The need for the tools those should be able to absorb this huge information and eliminate this problem is evident especially for IR systems. Text is not a simple sequence of words but carries a structure. It is essential to handle these uncontrollable complex structures of sentence, grammatical and lexical irrelevanc...
