This paper proposed a feature selection with privacy preservation in centralized network. Data can be preserved for privacy by perturbation technique as alias name. In centralized data evaluation, it makes data classification and feature selection for data mining decision model which make the structural information of model in this paper. The application of gain ratio technique for better perfo...

Encapsulation is a major concept in object-oriented designs as design pattern catalogues, approaches for alias control, and the need for modular correctness of components demonstrate. The way encapsulation can be formally specified in existing approaches has several shortcomings. We show how encapsulation in sequential Java programs is specified by means of a new concept, called encapsulation p...

Efficient surface reconstruction and reverse engineering techniques are usually based on a polygonal mesh representation of the geometry: the resulting models emerge from piecewise linear interpolation of a set of sample points. The quality of the reconstruction not only depends on the number and density of the sample points but also on their alignment to sharp and rounded features of the origi...

The University of Michigan-Dearborn team participated in the ad hoc task and submitted two runs in TREC 2005. The Genomics track is different from others since it focuses on document retrieval in genomics domain as opposed to general retrieval tasks such as question-answering, multi-lingual IR, etc. Since we were not familiar with the knowledge in biomedical field, we utilized the database publ...

This paper presents the design of Sharpened three stage CIC filter for decimation. The proposed decimation filter has Cascaded-Integrator Comb filter as first stage, Sharpened Cascaded-Integrator Comb filter as second and third stage. The CIC filter at first stage operates at input sampling rate, sharpened second stage operates at lower rate as compared to first stage and sharpened third stage ...

We present an approach to efficiently reduce shadow map resolution while retaining high quality hard shadows. In the first step, we generate a list of sample points that are seen from the camera and then project these into light space, much like Alias-free Shadow Maps. In the next step, we analyze the list of sample points on the GPU to construct a tight light frustum for shadow rendering. Afte...

We present a differential fixpoint iteration method to be used in static program analyses. The differential method consists of two phases: first we transform the program analysis equations into differential ones, and then we apply a differential fixpoint iteration to the equations computing with the differences from the previous iterations. We implemented the method for the exception analysis o...
