Modeling parasitic parameters of Through-Silicon-Via (TSV) structures is essential in exploring electrical characteristics such as delay and signal integrity (SI) of circuits and interconnections in three-dimensional (3-D) integrated circuits (ICs). This paper presents a complete set of self-consistent equations including self and coupling terms for resistance, capacitance and inductance of various TSV structures. Further, a reduced-order electrical circuit model is proposed for isolated TSVs as well as bundled structures for delay and SI analysis, and extracted TSV parasitics are employed in Spectre simulations for performance evaluations. Critical issues in the performance modeling for design space exploration of 3-D ICs such as cross-talk induced switching pattern dependent delay variation and cross-talk on noise are discussed. The error in these metrics when using the proposed models as compared to a field solver is contained to a few percentage points.

A Skipping SvS Intersection Algorithm

International Conference on Computing, engineering and Information, ICC

In this paper, we propose to improve the SvS algorithm by skipping elements of the smaller set for reducing a search boundary. The boundary of skipped element is determined by boundaries of elements prior to and next to it. We perform experiments on uniformly distributed random datasets to compare our algorithm with the standard SvS. We use regression analysis to get an equation for determining an appropriate skipping number. Our results show that the skipping SvS algorithm using the equation obtained can reduce approximately 41% on the number of comparisons of the standard SvS algorithm.

Robust audio steganography via genetic algorithm

Steganography is a technique used to transmit hidden information by modifying an audio signal in an imperceptible manner. The transmission must be possible in spite of subsequent imperceptible alterations (attacks) of the modified signal. We propose a novel approach of substitution technique of audio steganography. Using genetic algorithm, message bits are embedded into multiple, vague and higher LSB layers, resulting in increased robustness. The robustness specially would be increased against those intentional attacks which try to reveal the hidden message and also some unintentional attacks like noise addition as well.

Managing Malware in Higher Learning Institutions

International Conference on computer and Electrical engineering, ICCEE

"Malware" is an umbrella term that describes a variety of Internet-borne threats, including viruses, spyware,Trojan horses, spam, bots and more. This sophisticated and evolving security threat puts all businesses at risk, no matter how big or small. Malware creates unique challenges to higher learning institutions (HLI) in protecting their information assets. This is largely due to the fact that HLI information technology (IT) departments must balance between enabling a highly collaborative, non-restrictive environment and ensuring the confidentiality, integrity, and availability of data and computing resources. HLIs can proactively defend the network to reduce the risks associated with this threat by assessing the vulnerabilities and threats present in their networks and implementing appropriate multilayer security. A multilayer approach involves applying countermeasures at every layer of the computer network, from the perimeter routers and firewalls to users' personal computers in order to increase network security. The goal of this study is to propose a framework for network security protection against malware to increase the level of protection using non technical countermeasures.

Ambiguity is a major problem of software errors because much of the requirements specification is written in a natural language format. Therefore, it is hard to identify consistencies because this format is too ambiguous for specification purposes. This paper aims to propose a method for handling requirement specification documents which have a similar content to each other through a hierarchical text classification. The method consists of two main processes of classification: heavy classification and light classification. The heavy classification is to classify the requirement specification documents having similar content together. Meanwhile, light classification is to elaborate specification requirement documents by using the Euclidean Distance. Finally, slimming down the number of requirements specification through hierarchical text classification classifying may yield a specification which is easier to understand. That means the proposed method is more effective for reducing and handling in the requirements specification. © 2008 IEEE.

Recent advances in microarray technology allow scientists to measure expression levels of thousands of genes simultaneously in human tissue samples. This technology has been increasingly used in cancer research because of its potential for classification of the tissue samples based only on gene expression levels. A major problem in these microarray data is that the number of genes greatly exceeds the number of tissue samples. Moreover, these data have a noisy nature. It has been shown from literature review that selecting a small subset of informative genes can lead to an improved classification accuracy. Thus, this paper aims to select a small subset of informative genes that is most relevant for the cancer classification. To achieve this aim, an approach using two hybrid methods has been proposed. This approach is assessed on two well-known microarray data. The experimental results have shown that the gene subsets are very small in size and yield better classification accuracy as compared with other previous works as well as four methods experimented in this work. In addition, a list of informative genes in the best subsets is also presented for biological usage © 2008 IEEE.

Microarray device offers the ability to measure the expression levels of thousands of genes simultaneously. It is used to collect information from tissue and cell samples regarding gene expression differences that could be useful for cancer classification. However, the urgent issues in the use of gene expression data are the availability of huge number of genes relative to the small number of available samples, and many of the genes are not relevant to the classification. It has been shown that selecting a small subset of genes can lead to an improved accuracy of the classification. Hence, this paper proposes a solution to the problem of gene selection by using a multi-objective strategy in genetic algorithm. This approach is experimented on two benchmark gene expression data sets and it presented the experimental results. It obtains encouraging result on those data sets as compared with an approach that uses single-objective strategy in genetic algorithm. ©ISAROB 2008.

Gene expression data are expected to be of significant help in the development of efficient cancer diagnosis and classification platforms. One problem arising from these data is how to select a small subset of genes from thousands of genes and a few samples that are inherently noisy. This research aims to select a small subset of informative genes from the gene expression data that will maximise the classification accuracy. A model for gene selection and classification has been developed by using a filter approach together with an improved hybrid of the genetic algorithm and a support vector machine classifier. It is shown that the classification accuracy of the proposed model is useful for the cancer classification of one that widely used gene expression benchmark data set. ©ISAROB 2008.
