Bézier surfaces are widely used in CAGD. There are two main types of Bézier surfaces, namely the rectangular Bézier patch and the triangular Bézier patch. The two patches have different basic functions, but they share many common properties, so the conversion of one type to the other has aroused the interest of many researches. This paper deals with this problem by use operator representation...
Data intensive computing is having an increasing awareness among computer science researchers. As the data size increases even faster than Moore's Law, many traditional systems are failing to cope with the extreme large volumetric datasets. In this paper we use a real world graph processing application to demonstrate the challenges from the emerging data intensive computing and present a solution...

Packing portable executable (PE) file is an effective mean to protect software, but malware authors can also use packing to conceal their malicious executable string data and code. These methods make it difficult to analyze them in detail for virus analyst and software security researcher. They have to unpack the malware first. This paper illustrated the general unpacking methods and principles, using...
In the paper, it refers to the concepts of ontology, OWL and context, different context information is defined by the tuple method, and establishes the model of context-awareness based on ontology in Smart-Home, and then it introduces the model of reasoning and memory in detail; and studies the affections of ontology on the two models. At last, the paper explains the application of model by using...
Modeling of facial expression plays a very important role in the research of synthesis and recognition offacial expression. However the current facial expression model can not correctly represent the daily facial expressions. The nature of the facial expressions is analyzed. A qualitative description of the corresponding facial expression space is presented. And then a new facial expression space...
