Identification of Membrane Protein Interactions with an Ensemble Classifier
Authors: Zhao Pei-Ying , Ding Yong-Sheng
Published: December 2010

Membrane protein interactions play an important role in the compartmental organization of eukaryotic cells. Some membrane proteins are specifically targeted to some other ones and fuse with the target membrane to effect content mixing. Traditionally, biochemical methods have been used to identify the composition of interacting membrane proteins. However, these methods are generally restricted by the experimental conditions in practice. AdaBoost is a strong learning algorithm and it finds an accurate classification ruler. In this paper, we construct a classifier by combining with several FSVM classifiers. Jackknife tests on the working datasets indicate that the precision, sensitivity and accuracy are improved greatly. The results show that the proposed method may provide a novel approach to genetically identify membrane protein interactions.
A Gabor Filter-Based Feature Points Matching Approach
Authors: Niu Li-Pi , Shi Dong-Xin , Yang Ying-Yun , Zhang Wen-Hui
Published: December 2010

In this paper we propose a Gabor filter-based feature points matching approach. Gabor filters of different orientation are adopted to perform multi-orientational filtering on feature points that are to be matched, and vector elements of N-dimensional normed linear space are constructed by sub-image standard deviation of N-dimensional orientations. The similarity between feature points is described by ‘distance’ of two feature point vectors, thus it achieves matching between homogeneous feature points. The experiment results show the method is not sensitive to noise added in image and can be adapted to match images with great different gray scale levels. Moreover, the method has no special requirements on feature points.
SIP: Next Generation Packaging Technology
Authors: Shukla N. K. , Birla Shilpi
Published: December 2010

The term “packaging” has its role as: 1) Provide I/O connections to the semiconductor devices so the IC is tested and ready for board assembly. This is called IC packaging. 2) Integrate components into systems to form end product systems such as cell phones, PDAs, Laptops. This is called system packaging. Both the above IC and systems packaging are accomplished by interconnections or wiring at the package or board level. In future, the role of packaging is more than interconnections. The IC devices themselves began to integrate more and more transistors and functions, leading to what have been calling SOC or System- on-Chip with multiple systems functions in a single chip. This can be called horizontal or 2D integration of IC blocks toward system-level functionality. Such an approach presents design complexity and fundamental limits for computing, and integration limits for wireless systems. This led to 3-D packaging, often referred to as SIP or System-in-Package. In this review, starting from the introduction of SIP, an alternative approach of product design using SIP is discussed. After that SIP Integration which includes different technology, benefits are considered. Thereafter key issues in SIP integration and its future applications is discussed. Finally this work is compiled in conclusion.

Authors: Garcia Guillermo , Pereira Wilmer , Lujan Alejandro , Paladino Rosaura
Published: December 2010

Genetic Algorithms seek to solve optimization problems by implementing bioinspired techniques that simulate the evolution of living beings. This work explores a particular aspect of these techniques and proposes an individual mate choice criteria for the mating phase, called IBC. The main idea is to delegate the choice of the mate to the individuals, seeking to obtain a positive incidence in the evolution of the individuals throughout the generations. The choice criteria is codified within the chromosome, so it participates of the evolutionary process, giving each individual its own criteria. Experimental comparison between IBC, Rank and Binary Tournament show a positive tendency for the proposed technique.

Knowledge Discovery — Semantic Web
Authors: Kalarani S. , Uma Asst G. V.
Published: December 2010

Knowledge discovery is the process of automatically searching large volume of data for patterns that can be considered knowledge about the data. This is described as deriving knowledge from the input data. Knowledge discovery is defined as “the non-trivial extraction of implicit, unknown, and potentially useful information from the data”. Knowledge discovery is one of the key components of knowledge management system. Today's World Wide Web has large volume of data - billions of documents. So it is a time consuming process to discover effective knowledge from the input data. Here define knowledge discovery meta model (KDM) which defines an ontology for the software and their relationships for the purpose of performing knowledge discovery of existing data. Although search engine technology has improved in recent years, there are still many types of searches that return unsatisfactory results. This situation can be greatly improved if web pages uses a semantic markup language to describe their content, this paper describe SHOE a set of simple HTML ontology Extensions. SHOE allows World-Wide Web authors to annotate their pages with ontology-based knowledge about page contents. This paper contains an examples showing how the use of SHOE can support a new generation of knowledge-based search and knowledge discovery tools that operate on the World-Wide Web. Identifying patterns as the process of knowledge discovery in an university ontology is taken as case study.
A Model Checker Based Approach of Attack Path Enumeration for Network Security Management
Authors: Bagchi Atig , Ghosh S. K.
Published: December 2010

In a typical network, an attacker usually breaks into the network through a chain of exploits, resulting from its inherent vulnerabilities. Such a chain of exploits represents an attack path and for a network all such chains of exploits taken together form an attack graph. Attack graphs are tools which aid in the identification of risks associated with a network as a whole. The use of attack graphs in the context of multi-stage network security is an active research area. Various approaches have been reported in literature for generation of attack. In this paper, we present a novel approach to enumerate all the acyclic attack paths in a network using a custom algorithm over a model checker's solution.

Published: December 2010

A system able to capture coherence of sequential foci based on an absolute expression called “CEE”, detecting and disambiguating multiple contextual knowledge representations arising in complex sentences / adnominal phrases / co-occurrence expressions / main and subordinate clauses / emoticons, is described in this paper. In the e.g. [Though the memory capacity of this hard disk is big (positive), its clatter is big (negative).], the same word “big” appears twice, however, because the latter have different meaning according to context, its evaluation polarity reverses. Furthermore, in order to capture the whole meaning of this sentence, detecting the antecedent of “its” (This antecedent is “hard disk”), an anaphor, becomes also necessary. The ratio of correct evaluation from 2500 customer reviews is 75.0 %.

EOrBAC- Based Active Directory Management
Authors: Hassan Ahmad A. , Bahgat Waleed M.
Published: December 2010

A corporate network consists of many individual network security components. Firewall, active directory, and IDS are some examples of these components. Each network security component has its own high level security policy which is translated into low level security mechanisms. There is a wide gap between high level and low level representation of security policy making enforcement of high level security policy faces some essential difficulties. Consistency, verification, and maintenance are the major ones of these difficulties. One approach to overcome these difficulties is to present security policy in an intermediate level and then automate the translation of the intermediate level security policy into low level security mechanisms. Extended Organization Based Access control (EOrBAC) model is valuable step towards introducing this intermediate level. One of the major advantages of EOrBAC is its ability to model most network security components. This paper extends the work of EOrBAC by applying its concept on active directory network security component. Also, an EOrBAC based network security management toolkit is developed to realize this approach.

Published: December 2010

Image reconstruction is the art of obtaining a three dimensional scene from 2D images.. Approaches for image reconstruction are, Shape from shading, Shape from texture, Shape from motion, and Shape from stereo. In Shape from stereo or the Stereo Image Reconstruction only two images are used to reconstruct the scene. The most difficult problem in Stereo image reconstruction is the correspondence problem. Matching each pixel is a complex process results in many mismatches and inaccurate three dimensional scene. We have done matching in two levels, the first level is Feature based matching, the second level is Area-based matching. We have joined the two levels to obtain a more accurate pixel by pixel correspondence. We also obtained an adaptive search range and window size for each pixel to reduce the mismatches. Our procedure introduced high accuracy results and more dense 3D scene.

A Hybrid Method for Global Optimization of Multivariate Polynomial
Authors: Xue Jiwei , Zhao Lili , Xiang Xingshang
Published: December 2010

A hybrid algorithm for global optimization of multivariate polynomial with bound constraints was proposed. The algorithm combines numerical, interval and symbolic methods. Interval methods can obtain small intervals and are guaranteed to contain the global optimum in the presence of rounding errors. Almost all interval-based global optimization methods use interval Newton method to verify existence and uniqueness of a solution to the problem. However, existence and uniqueness verification of a solution to a problem will not succeed when the Jacobi matrix is singular at some point in the region. To overcome the interval methods' shortcomings, we propose to use the symbolic method proposed by Pedersen et al. to improve the system's efficiency and to guarantee the interval methods' integrity. The hybrid method can solve problems that separately none of traditional methods is unable to solve. Furthermore, all the methods in our algorithm have nice properties for parallelization. So the performance of the system can be improved further.

Authors: Chen Tao , Guo Deke , Luo Xueshan , Liu Junxian , Shu Zhen
Published: December 2010

Traditional data collection protocols suffer “hot spot” problem heavily in area around the sink node. Recently proposed schemes using mobile sinks try to balance the load with the cost of sink mobility. However, most approaches are based on unit disk graph (UDG) model, which is inaccurate in physical world. We propose an UDG-free solution for data collection with mobile sinks using dominating set and traveling salesman problem (TSP) techniques. A distributed algorithm for dominating set construction is presented, and the result set is used in approximate TSP algorithm to generate a moving path. Our solution not only reduces communication overhead, but also balances the load distribution.

Authors: Zheng Qiaoshi , Gao Deyuan , Shi Liwen , Chen Jie
Published: December 2010

Prefetching is a common technique of tolerating the memory latency. However, it rapidly increases the communications traffic between the upper-level storage and the lower-level. Based on the analysis of access patterns of the SPEC benchmarks, we propose a novel push structure, in which the L2 cache can actively push instructions and data to the L1 cache at a proper time without the request from the L1 cache. By using a cycle-accurate simulator running SPEC benchmarks, the experimenting results showed that our push structure can significantly reduce the access to the L2 cache by 34.6%. Therefore, our push structure can effectively reduce the communications traffic between the L1 and the L2 cache. Our push structure also averagely increases the IPC by 6.6%.
Steganalysis Based on the 2-D Histogram in Frequency Domain
Authors: Deng Qian Lan , Lin Jia Jun
Published: December 2010

This paper proposed an image steganalysis scheme based on the statistic moments of 2-D histogram in frequency domain. The difference is calculated in three directions, horizontal, vertical and diagonal towards adjacent pixels to obtain three-directional differential images for a natural image. Then the features for steganalysis are extracted from the 2-D DFT of the 2-D histogram of image itself and its differential images. Support vector machine (SVM) with RBF kernel is applied as classifier to distinguish between stego images and cover images. We test the performance of our proposed steganalysis method over spread spectrum (SS) data hiding method, LSB method and QIM data hiding method. The experiment results have proved that the proposed method is effective in attacking these steganograhic schemes applied in spatial domain.

The source image is decomposed into low-frequency image and high-frequency images by à trous contrast pyramid transform. Then apply directional filter bank to each high-frequency. The different fusion rule is adopted in low-frequency image and high-frequents subbands. Finally the fused image is obtained through inverse transform. Experimental results show that the proposed method is valid to fusion of infrared and visible images, and has better subjective visual effect.

As the concept of Digital City becomes more and more important, people are inclined to building digital cities. In order to manage cities better, it is necessary to add remote monitoring to digital cities because it could solve the problem that something is not convenient for field survey though remote monitoring in digital cities. In addition, Google Earth(GE) is one of the most convenient platforms for building digital cities. Therefore, we propose a remote monitoring system based on GE. We employ the GIS searching & orientation module to search and locate places where users want to monitor on GE. Besides, the monitoring module is used to monitor places by updating image overlays on GE. And we utilize the voice guiding module to tell users the information about places in voice. Thus, it will be convenient for city management though remote monitoring based on GE.

Learning process is very important in academic industry. Students are the person that will give their service to the country after they graduated. As an academician, lecturer responsible in making sure their students are having skills that needed by industry. The industry in Malaysia always complaint that Malaysian student are having no skill. So, with this problem, we applied problem-based learning method to make our students can solve whatever problem given by superior, critical thinking in solving the problem, can work independence and minimized supervision and others. The PBL method was introduced to the Faculty of Computer Systems and Software Engineering (FSKKP) second year students in the Bachelor of Software Engineering. The subject is Formal Methods 3 credit hours. The number of students is 88. We analyzed 88 students' assignment to see their performance of construction of formal specification. Using this method help student in gain skill that required by the industry at the same time to construct formal specifications. This approach can train our student more critical thinking, independent, confidence, developed team working and others.

Along with the rapid growth of the Web Service(WS), how to choose a suitable WS for consumers becomes a hotspot. Nowadays, researchers focus on the selection method based on quality of service (QoS). It does work but need a good model and methods for the selection based on QoS. The work in this paper is based on an extended service model. It puts forward a new model for WS. Based on this service model, service provider can define the attributes for a WS to describe the QoS of the WS. And in the similar matter, service consumer can use these attributes to give an evaluation for the WS. This service model and related methods we designed and implemented are already benefited in a IBM Global SUR (Shared University Resources) project and is running in the real world to collect and catalog the public WS from Internet.

In this paper, two algorithms, Differential Evolution Algorithm (DEA) and Genetic Algorithms (GAs), are applied to the offline identification of induction motor parameters. DEA is compared with the prediction errors and the genetic algorithm via determination parameters using nameplate data like starting torque, breakdown torque, and full-load torque in two different cases. Consequently, it is seen that DEA can be find more precise parameter values than the genetic algorithm and especially convergences to global optimum not to be stuck local optimum.

Published: December 2010

Developing a weapon that can be utilized to intercept and destroy a ballistic missile during the boost phase of its flight is the first step in eliminating the threat of the attacking ballistic missile. Boost phase interception is considered successful, when a complete destruction of the missile and its on board munitions is achieved. Various weapon systems have been developed for boost phase interception of ballistic missiles. This work is applied to one of these systems which is the ground-based intercept missile. The requirements for the interceptor effectiveness will be discussed. The work is based on simulated engagements between the attacking ballistic missile and the interceptor employing proportional navigation for the guidance law. The distance between the target missile warhead and the interceptor at the end of engagement, which is called the miss distance, is calculated as a measure of the interceptor performance. The effect of changing the navigation ratio on the acceleration requirement and the total flight time for the interceptor to attain minimum miss distance is illustrated. The Matlab programming environment is used to carry out the mathematical analysis and plotting the output results.
