Int J Inf Process 2011, 5(3), 37-46.

Exploring the functions of proteins is an important tool for understanding cellular processes in living organism. The general source data for analysis are the peptide sequences. The most common algorithms used to compare a pair of nucleotide sequence are Global alignment algorithm or local alignment algorithm. Analysis of these algorithms show that time complexity required to the above mentioned algorithms is O(mn) and space complexity required is O(mn), where m is size of one sequence and n is size of the other sequence. This is one of the major bottlenecks as most of the sequences are very large. The proposed Coding Region Sequence Analysis(CRSA) algorithm presents a method to reduce both time and space complexity by meaningfully reducing the size of sequences by removing not so significant exons using wavelet transforms. DSP techniques supply a strong basis for regions identification with three-base periodicity.

Objective of this paper is to classify recently released Indian coins of different denomination. The objective is to recognize the coins and count the total value of the coin in terms of Indian National Rupees (INR). The system designs coin recognition which uses by combining Robert's edge detection method, Laplacian of Gaussion edge detection method, Canny edge detection method and Multi-Level Counter Propagation Neural Network (ML-CPNN) based on the coin Table 1. In this paper, it is proposed to introduce ML-CPNN approach. The features of old coins and new coins of different denominations are considered for classification. Indian Coins are released with different values and are classified based on different parameters of coin such as shape, size, surface, weight and so on. Some countries' coins are having same parameters, but with different value. This paper concentrates on affine transformations such as simple gray level scaling, shearing, rotation etc. The coins are well recognized by zooming processes by which a coin size of the image is increased. To implement the coin classification, code is written in Matlab and tested with simulated results. A method is proposed for realizing a simple automatic coin recognition system more effectively. The Robert's edge detection method gives 93% accuracy and Laplacian of Gaussion method gives 94%, the Canny edge detection method yields 97.5% result and the ML-CPNN approach yields 99.5% of recognition rate.

Int J Inf Process 2011, 5(3), 1-13.

World Wide Web (WWW) is the repository of large number of web pages which can be accessed via Internet by multiple users at the same time and therefore it is Ubiquitous in nature. The search engine is a key application used to search the web pages from this huge repository, which uses the link analysis for ranking the web pages without considering the facts provided by them. A new application called Probability of Correctness of Facts(PCF)-Engine is proposed to find the accuracy of the facts provided by the web pages. It uses the Probability based SIMilarity function (SIM) which performs the string matching between the true facts and the facts of web pages to find their probability of correctness. The existing semantic search engines, may give the relevant result to the user query but may not be 100% accurate. Our algorithm probes for the accuracy among the facts to rank the web pages. Simulation results show that our approach is efficient when compared with existing Voting and Truthfinder[l] algorithms with respect to the trustworthiness of the websites.

Since its inception, cloud computing has faced a number of challenges, like data migration, adoption of new policies etc. but the most challenging and important among them has been the security and risk issues related to it. Cloud computing provides a user, the provision to use various computing resources over the internet on a leased basis. This new model of computing has gained its popularity among various organizations and individuals due to its cost effectiveness and versatile features. But as it is common to any other computing infrastructure, cloud computing environment is also prone to security threats, may be up to a larger extent than traditional computing, which is hindering its growth. Using fully homomorphic schemes, as proposed in this paper, it would be possible for a user to store their data in the cloud in an encrypted form and perform some specific computations on the encrypted data, without the cloud server's knowledge about the data and computations at all. Hence it will help the cloud service providers to develop a secured cloud infrastructure and build trust among the users.

In mobile Ad hoc networks, the networks topology changes dynamically and partition among mobile nodes occur frequently. These are due to unpredictable mobility of mobile nodes and each mobile node acts as a router which discover and maintains routes, and forward a packets to other nodes and address the problem of replication in mobile ad hoc networks by exploring group mobility approach. Group mobility refers to the scenario where several mobile nodes tend to move together. Group mobility approach is used to increase the data accessibility among mobile nodes through data replication and consistency group management. It also guarantees basic level of system performance, such as throughput, delay and reduces the network traffic among mobile nodes.

This paper deals with an approach of likelihood ratio based score fusion technique where appearance and shape based facial features have been used to enhance the efficiency of existing face recognition system. Active Shape Model (ASM) has been used to extract the appearance and shape based facial features. Two different types of features have been used in this work in such a way that when the appearance based feature contains noise then shape based feature retains its efficiency and the overall performance will be maintained in a satisfied level. Same thing will be happened when the shape based feature degrades with more noise compared with appearance based feature. Hidden Markov Model (HMM) has been applied for learning and testing model for the proposed face recognition system. Likelihood ratio of each appearance and shape modality have been measured using reliability measurement technique and log likelihood ratio scores are fused to evaluate the final face recognition performance. To measure the performance of the proposed system, Olivetti Research Laboratory (ORL) database has been used with addition of various noises at different level. Experimental results and performance analysis show the superiority of the proposed face recognition system.

This paper proposes a web cache replacement policy based on semantic content of the pages cached at the client side. Two models namely Clustered Model(CM) and Relational Model(RM) are proposed that focus on the Dynamicity which refers the dynamic nature of the content and the Semantic content which exhibits the relation of information available among cached web pages and hence the name DynaSem. The proposed policy marks the page for eviction prioritized by Eviction Index (El) in CM and Relation Index (RI) in RM. CM uses an interface with a. web browser incorporated into it. The Trie data structure that enables the searching process to be more efficient has been framed to store the well-known categories of cached content as clusters. Pages with highest El are marked for eviction. RM employs a technique to reveal the relation among cached documents. It evicts documents that are less related(minimum RI) to an incoming document which needs to be stored in the cache to ensure that only related documents are cached; hence the contents of the cache represent the documents of interest to the user and those which are of more static in nature. The proposed policy has been developed to incorporate two algorithms- one to find the dynamic count of the given web page P and the other to the find semantic relation between the pages cached. Both the models(CM and RM) are used to establish the semantic relation. The policy has been simulated under model driven simulation with the help of an input set consisting of a few web pages. The parameters pertinent to cache replacement algorithms are computed and the result shows there is a factual improvement compared to the original semantic based policies.

Storage management is a general storage industry phrase that is used to describe the tools, processes, and policies used to manage storage networks and storage services such as virtualization, replication, mirroring, security, compression, traffic analysis and other services. Storage management is a process used to optimize the use of storage devices and to protect the integrity of data for any media on which it resides. Optimizing the use of storage devices translates into making sure the maximum amount of usable data is written to and read from these units at an acceptable rate of response. Optimizing these resources also means ensuring that there is an adequate amount of storage space available while guarding against having expensive excess amounts. This notion of optimal use ties in to two of the main areas of storage management: capacity and performance. There are many different devices on which data can be stored. The selection of devices to best meet storage needs depends primarily on three factor, Performance, Availability, Cost. How you choose to manage your storage determines how you control the devices that store the active data on your system. To be useful, active data must be available and remain persistent even after unexpected events, such as a hardware or software failure. The storage allocation strategy used in each of the three data areas, namely static data area, heap, stack, are different.Stack allocation lays out storage for all data objects at compile time. Stack allocation manages the run-time storage as a stack. Heap allocation allocates and deallocates storage as needed at runtime from a data area known as heap.

The initial impact of outsourcing, and the relatively lower cost of international human resources in developing third world countries led to a massive migration of software development activities from corporations in North America and Europe to India and later: China, Russia, and other developing countries. This approach had some flaws, mainly the distance / timezone difference that prevented human interaction between clients and developers, but also the lower quality of the software developed by the outsourcing companies and the massive job transfer. This had a negative impact on many aspects of the software engineering profession.

Medical image processing and analysis is the tool to assist radiologists in the diagnosis process to obtain a more accurate and faster diagnosis. In this work, we have developed a neural network to classify the computer tomography (CT) brain tumor image for automatic diagnosis. This system is divided into four steps namely enhancement, segmentation, feature extraction and classification. In the first phase, an edge-based selective median filter is used to improve the visibility of the loss of the gray-white matter interface in CT brain tumor images. Second phase uses a modified version of shift genetic algorithm for the segmentation. Next phase extracts the textural features using statistical texture analysis method. These features are fed into classifiers like BPN, Fuzzy k-NN, and radial basis function network. The performances of these classifiers are analyzed in the final phase with receiver operating characteristic and precision-recall curve. The result shows that the CAD system is only to develop the tool for brain tumor and proposed method is very accurate and computationally more efficient and less time consuming.

Asian sci 2012, 7(2), 143-9.

This paper investigated how doctors in remote rural hospitals in South Africa use computer-mediated tool to communicate with experienced and specialist doctors for professional advice to improve on their clinical practices. A case study approach was used. Participants were purposively selected. Ten doctors were selected from ten hospitals in the North West Province. Data were collected using semi-structured open ended interview questions. The interviewees were asked to tell in their own words the average number of patients served per week, processes used in consultation with other doctors, communication practices using computer-mediated tool, transmission speed of the computer-mediated tool and satisfaction in using the computer-mediated communication tool. The findings revealed that an average of 15 consultations per doctor to a specialist doctor per week was done through face to face or through telephone conversation instead of using a computer-mediated tool. Participants cited reasons for not using computer-mediated tool for communication due to slow transmission speed of the Internet and regular down turn of the Internet connectivity, constant electricity power outages and lack of e-health application software to support real time computer-mediated communication. The results led to the recommendation of a hybrid cloud computing architecture for improving communication between doctors in hospitals. Although this study had a limited number of participants, the findings were unexpected, and therefore, of interest to doctors who intend using computer-mediated tool to improve the performance of their clinical duties. It is also of interest to those who intend to implement e-health initiatives in rural hospitals in South Africa.

The authentication protocols based on classic cryptography use public-key cryptosystems for establishing the common key and some of them have been proven to be secure but they require high amount of resources and they need large keys. This kind of protocols is secure enough even if a small key is used this is another advantage. In this paper we presents secure cryptographic authenticated group key transfer agreement and performance evolution of MAC addresses based protocol for distributed network environment. The protocol is developed for group communication and every member of the group has secret information and the communication start when all this information is put together. So, without online two members can't communicate to each others. We, also, present some situations where this kind of protocol is needed. It's well known that in wireless LAN, authenticating nodes by their MAC addresses is secure since it's not easy for an attacker to learn one of the authorized addresses and change his MAC address accordingly. In order to the MAC address prevent spoofing attacks, we propose to use dynamically changing MAC addresses and make each address usable for only one session. The scheme we propose does not require any change in 802.11 protocols and incurs only a small performance overhead. One of the nice features of our new scheme is that no third party can link different communication sessions of the same user by monitoring MAC addresses therefore our scheme is preferable also with respect to user privacy.

Firewalls play the crucial role in the computer security. The overall performance of a firewall depends upon the Time required in rule matching. As the number of the entries increase in the list, the speed of firewall becomes slow. Time required in rule matching is directly proportion to the size of the list. To improve the overall performance of a List based firewall, new multi level Heap Based rule set for the packet filter is presented. In this scheme system maintains two different rule set for incoming & outgoing packets, so average rule set size is reduced to n/2. Rule set for incoming and outgoing packet contains only three parameters to evaluate that packet's action type (i.e. - either forward or discard the packet). Using the multilevel heaping the performance of a packet filter improves up to level O (n₁+n₂+n₃). This scheme also removes the anomalies of the rule set.

Nothing has changed the world around us the way digital technology and computers have. Computers have entered every aspect of our life and the environment around us. Real time systems are playing vital role in daily life. In just a few decades ago, real time systems are reshaping the way people live, work, and play. Real time systems come in an endless variety of types, each exhibiting unique characteristics. For example, most vehicles driven today embed intelligent computer chips that perform value-added tasks, which make the vehicles easier, cleaner, and more fun to drive. Even private homes are being filled with intelligent appliances, which facilitate and enhance everyday life. Real- Time systems span several domains of computer science. They are defense and space systems networked multimedia systems, embedded automotive electronics etc. The purpose of this chapter is to give an overview of the broad area of real-time systems. This task daunting because real time systems are everywhere and yet no generally accepted definition differentiates real-time systems from non-real-time systems. A system is defined as being real-time if it is required to respond to input stimuli within a finite and specified time interval. The stimuli being either an event at the interface to the system or some internal clock tick that is, at least notionally, coordinated with the passage of time in the system's environment. Real-time systems are found in a wide range of applications areas, from simple domestic appliances to multi-media systems, large scale process control and safety critical avionics. In some systems the required response times are measured in milliseconds, in others it is seconds or even minutes.

Cloud Computing is the result of evolution and adoption of existing technologies and paradigms. The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them. The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles. Cloud computing has several distinct characteristics that distinguish it from a traditionally hosted computing environment. Users often have on-demand access to scalable information technology capabilities and services that are provided through Internet-based technologies. These resources run on an external or third party service provider's system instead of on locally hosted servers unlike traditional systems directly under the user's personal or institutional control; cloud computing services are fully managed by the provider. Typically, many unaffiliated and unconnected users share the service provider or vendor's infrastructure. Using cloud services reduces the need to carry data on removable media because of network access anywhere, anytime.

Cloud computing is the latest effort in delivering computing resources as a service. It represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to consumers over the internet from large-scale data centres - or "clouds". "Cloud" computing - a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services and many other things. Whilst cloud computing is gaining growing popularity in the IT industry, academia appeared to be lagging behind the rapid developments in this field. This is the first systematic review of peer-reviewed academic research published in this field, and aims to provide an overview of the swiftly developing advances in the technical foundations of cloud computing and their research efforts. Structured along the technical aspects on the cloud agenda, we discuss lessons from related technologies; advances in the introduction of protocols, interfaces, and standards; techniques for modelling and building clouds; and new use-cases arising through cloud computing.

Today's world is moving at an ever increasing pace. New technologies, opportunities, threats all force companies to have the ability to be able to change rapidly in order to stay competitive and survive in increasingly harder business climates. Authors look at how new generations working with new types of media can play a vital role in how a company goes about its change management decisions. The focus is centered on the use of social media in a business environment. Come to the conclusion that an implementation of social media will yield faster and better communications within a company and also make the company more transparent where every employee's opinions can be read, documented and saved for future use. This information can later be utilized when carrying out and managing change in a business environment. Social media is a, at least in the field of academia, young phenomena. There has not been an extensive research in the subject, especially not with regard to uses in organizations. For this reason we have chosen to make use of many sources from as diverse fields as possible. Focused on finding at least two, of each other independent sources, wherever possible to verify statements. Also relied on our own experience from working with social media and the knowledge gained through the course of consuming literature on the subject to assess sources. Apart from the sources we have listed in our reference section we have also taken part of much more material to further our own basic knowledge and understanding of social media.

Vulnerability scanning is one of the optimistic information security technologies in the Internet and network security area. However, the current vulnerability scanner (VS) products vary extensively in the way that they can detect vulnerabilities, as well as in the number of vulnerabilities that they can detect. Often, VS products also declare their own vendor-specific vulnerability category, which makes it difficult to study and compare them. Although Common Vulnerabilities and Exposures (CVE) provides a means to solve the different vulnerability names used in the different VS products; it does not standardize vulnerability categories. Presents a way to classify the vulnerabilities in the CVE repository and proposes a solution for standardization of the vulnerability categories using a data-clustering algorithm.

Delivered software is required to be modified because of some fault, user requirement or because of some new included feature. In such case, when the code of some software is modified, it is also required to test the software again. But instead of testing the complete software again, only few selected test cases are regenerated. It is desired that there should be an effective approach so that an optimized solution for test sequence generation can be found out with low cost. Several researchers have used different techniques for fault optimized and cost effective test sequence generation and one of them is DYNAMIC PRIORITIZATION technique which is used for scheduling test cases in an order so that their effectiveness can be increased at meeting some performance goal. The work done in the regression testing will be discussed as well as current status of work that has been done on Regression sequence generation and some suggestions for its future perspectives will be discussed.
