Virus signature library is key factor for performance of anti-virus programs considering accuracy and scanning speed. To ensure coverage of various emerging viruses, the scale of signature library grows larger and the consequence is lower efficiency because of the need of matching against more signatures. This paper's target is to decrease the signature mapping cost by optimizing signature library...
Detector plays an important role in self and non-self discrimination for intrusion detection system, which makes detector generation a kernel algorithm for artificial immune system. In this paper, firstly current used binary matching rules are listed, characteristics of which are analyzed. And detector generation algorithm is divided into three main processes, including gene library, negative selection...
The purpose of this research was to assess the level of computer literacy among the Semai tribe in Kampung Bukit Terang, Kampar, Perak, Malaysia. Forty questionnaires were distributed to the respondents who were conveniently available at the time of the visit. With the help of forty university students, 39 (97.5%) completed sets were returned. The descriptive analyses showed that 30.8% of the respondents...
The development of modern information technology has promoted the construction of digital learning environment which represented as digital learning harbor, in this situation, teachers' learning community became an effective shortcut for teachers' professional development. This paper comes from digital learning harbor project, analyses and defines the connotations of teachers' learning community in...
Nowadays, computers are indispensable tools for most of everyday activities ranging from consumer electronics to industrial process automation. Complexity of new applications leads computer engineers to use embedded systems in order to develop high performance technological solutions that can achieve high speed processing while exploiting hardware resources efficiently. In order to develop embedded...
This paper describes a method for clothing coordination recommender systems to consider familiarity by using internal activity factors. We implemented the method in our system for evaluation and conducted experiments using pairs of Kansei words to reflect the impressions of participants. The experimental results show the effectiveness of the method. This method should also be useful for other systems,...
In this paper, the attribute reduction strategy is syncretized into classification algorithm of the decision tree and applied to criminal behavior analysis. Finding implicit knowledge in the criminal database by this method can utilized to assist making decision for police quickly and accurately. The classification algorithm of the decision tree based on rough set is proposed for multi-attribute data...
Since the blog service brings a wealth of information resources, blog search and classification are showing their great research value. This paper focuses on the blog classification on the personal vs. official facet. Our system adopts a two-stage strategy; in training model, lexicons are built automatically; in classification model, scoring and ranking are carried out orderly. Our experimental results...
Cerebral perfusion pressure (CPP) is the net pressure gradient causing blood flow to the brain. It must be maintained within narrow limits because minute fluctuations in pressure could cause brain tissue to become ischemic or could raise intracranial pressure (ICP). In this paper, two types of transducers were proposed to measure the CPP from conscious rats. One transducer was manufactured with a...
This article is aimed on software requirements specification (SRS). At the beginning an introduction to requirement analysis field is provided. After that we point out the place of user requirements in software development life cycle. We are trying to propose basic method for the purpose of reusing Domain Model as basis of requirement generation in order to save initial time for defining user requirements...
In this paper, we study the singular solutions of semilinear elliptic equations. We use the method of moving spheres to prove the symmetry and nonexistence of singular positive solutions.
Transactional memory (TM) is a new shared resource synchronization mechanism which was proposed to ease the difficulty of parallel programming. Currently, most hardware transactional memory systems leverages the extended directory based cache coherence protocol to resolve transaction conflicts; seldom research has been conducted to extend a snoopy coherence based chip multi-processor with TM support...
