Dynamic Resource Allocation For Cloud Data Center Using Live Migration Of Virtual Machines[Full-Text ] Sankar.B, Arunprakash.TCloud computing permits business customers to scale up and down their asset usage based on desires. Numerous of the touted gains in the cloud model arrive from resource multiplexing through virtualization expertise. In this paper, we present a system that values virtualization expertise to allocate facts and figures center assets dynamically founded on application claims and support greencomputing by optimizing the number of servers in use. We insert the concept of “skewness” to measure the unevenness in the multidimensional asset utilization of a server. By minimizing skewness, we can combine distinct types of workloads nicely and improve the general utilization of server resources. We evolve a set of heuristics that prevent overload in the scheme effectively while saving power utilized. Trace propelled replication and trial outcomes demonstrate that our algorithm achieves good performance.

A Novel Approach for Test Path Generation and Prioritization of UML Activity Diagrams using Tabu Search Algorithm[Full-Text ] Gargi Bhattacharjee, Priya PatiSoftware testing is highly vital to the development of any software. Testing ensures the quality of software and in turn increases its reliability and robustness. The prime focus lies in minimizing the expenses incurred in testing. To test software, the major problem lies in generation of test cases. Software specifications are the main sources for generating them. Software specifications may be UML diagrams, formal language specification, or natural language description. Testing professionals have now shifted their attention to UML. The software specification used in this paper is UML Activity Diagram. While testing the software, we need to identify all the paths in order to ensure complete testing. Test paths in software can be identified through existing algorithms. But the problem arises when we have to find out the most critical path among them as they are the ones most likely to be executed. In this paper, we have employed a Meta heuristic approach called tabu search to find out the path with highest priority so that it can be tested first. Identifying the most critical path increases, the testing efficiency.

A mobile Ad hoc network (MANET) represents system of wireless mobile nodes that can self organize freely and dynamically into arbitrary and temporary network topology. Routing is the task of directing data packets from a source node to a given destination. There are many routing protocols in MANETs basically classified as Flat routing, Hierarchical and Geographical position assisted routing, in which performance of AODV & OLSR flat routing protocols has been evaluated. The main method for evaluating the performance of MANETs is simulation. They can be studied formally as graphs in which the set of edges varies in time. This paper is subjected to Ad-hoc on demand distance vector (AODV) routing protocol, performance with IEEE 802.11 MAC protocol in chain topology for various number of nodes and evaluated its performance. We investigated the performance metrics namely throughput, PDR (Packet delivery ratio), average delay and average jitter by varying network size up to 80 nodes through NS-3 simulation. Almost always the network protocols were simulated as a function of mobility, but not as a function of network density in chain topology. The main interest of this paper is to test the ability of AODV over OLSR routing protocol to react on chain network topology as number of nodes changes. The simulation is performed through the simulation tool NS-3(Network simulator-3) due to its open source simplicity and free availability. With the help of NS-3, result shows that AODV’s performance in average delay and average jitter metrics is better than OLSR.

Skin Texture Analysis Using Matlab[Full-Text ] Bipin Mokal, Aarti Bokade, Uttam Bagal, Swati Checker, Neethu Rajan & G. D. Jindal The objective and quantitative assessment of the skin is important in medical and cosmeceutical research. Assessment of color is an important element for analyzing the surface of the skin, which is usually determined subjectively by a doctor or using color analysis devices. These devices however cannot provide correct color information because color is construed from the mean value of the observation region, and analysis of color distribution is impossible. The purpose of this project is to develop an objective analysis method to permit skin parameters of each pixel. The project is focused on methods of skin analysis based on various algorithms which determine the color of skin. The tests are based on skin pixels on a combination of hue, saturation, intensity and RGB values of individual pixels. The detection of various skin parameters includes the detection of skin tone along with the percent improvement before and after the treatment. MATLAB software was used for programming and processing. Processed output was displayed on the monitor.

Multiple Antenna Selection of multi-Relay System using GSC Scheme[Full-Text ] Ahmed El-Mahdy, Seif El-Wakil, and Ahmed Elbakly Due to the emergence of very high-data-rate wireless communications, the adaptation of traditional diversity systems is required so that some performance is sacrificed for complexity reduction. With this goal in mind, we investigate the performance of muti-antenna multi-relay system when the generalized selection combining (GSC) is used to select and combine a number of diversity branches. The performance is measured in terms of bit error rate (BER) and is evaluated for both amplify and forward and decode and forward protocols. The considered channel is a slow flat fading channel. The performance is evaluated for known and estimated channel. The channel is estimated using least square algorithm. The performance of channel estimation algorithm is measured in terms of mean square error of estimation. The result shows that a reduction in complexity and power consumption is achieved for the multi-relay when GSC is used at the expense of some performance degradation.

Drainage of Excess Irrigation Water at El-Rabwa City, Giza Governorate, Egypt.[Full-Text ] Waleed A. Ogila, Ali H. Al-batal, Noha A. RabieIn arid and semi-arid regions, drainage of excess irrigation water is the next logical step towards improving water management in golf areas and reducing the environmental impacts of subsurface drainage flow. The urbanization and land development in Egypt started more than three decades ago. The construction activities extended from the narrow district in the Nile Valley and Delta toward the vast desert fringes. Desert soil is a problematic soil that may include expansive and collapsible soils, sandstone and limestone in one site. Groundwater related problems in such sites are due to the fact that the presence of water might not be taken into consideration during design and construction phases. El-Rabwa City is located in Giza Governorate at about 25km west of Cairo City. The goal of this paper is to undertake a study of the drainage of irrigation water considering both the topographic features of the ground and the subsurface layers that include impermeable clay layer with variable elevations. In addition, the study aims to investigate possible influence of the excess water on the foundations of the residential units. Hair fractures of some residential units were observed in the area. Excess of irrigation water was thought to be one of the most reasons of the observed fractures. A total of over 300 boreholes, supplemented by additional investigation boreholes, were reviewed. The geotechnical data of the boreholes were used to develop geological model for the site. The geological model of the site revealed the presence of top permeable layers (sand or fractured rock) underlain by impermeable clay layer. The surface topography, together with the permeability of the subsurface layers, determines the division of the excess irrigation water to runoff and infiltration water. The collected geotechnical data was used to study the topography of the subsurface clay layer that plays major role in determining the flow pattern of the excess water portion that permeate or infiltrate to the subsurface. The identification of both the topography and the geological models of the subsurface is a key factor in selection or the design of the alternative drainage systems for the excess irrigation water that are presented in the paper.

A FPGA Implementation of High Security Hybrid Reconfigurable Cryptographic Processor with RSA and SEA[Full-Text ] A.Chitra, K.Sangeethalakshmi,P.Sivalakshmi, R.ShimilaData security is in Demand in everyday life of Digital World, since Digital data’s can be reproduced much easily. To achieve the maximum security required a Parallel Processing, User Reconfigurable Cryptographic RISC Microprocessor is proposed in our paper. Rather than protecting the data using tools and external codes, a microprocessor is specially designed in our project to offer maximum digital security. Cryptographic processor can be classified either as asymmetric cryptography or a symmetric cryptography processor. Asymmetric cryptography has the advantage of Reception security but has the limitation of High resource Utilization. And a symmetric cryptography processor has the limitation of single key security but comparatively has the advantages of low area, resource and power consumption. Thus in this project we are proposing Hybrid architecture in which both the advantage of asymmetric and symmetric cryptographies are combined. For implementation, Asymmetric RSA cryptography and a symmetric lightweight SEA encryption is combined to mutate a reconfigurable Cryptographic processor.

PRELIMINARY SURVEY OF WOOD SPECIES CAVITIES PREFERRED BY HONEYBEES IN NIGERIA[Full-Text ] Aiyeloja, A. A and Adedeji, G. AThough woods remain the principal nest service provider to Apis mellifera Scutellata in Nigeria, a technical information/knowledge gap on the wood species preferred by the bees still remains. Therefore, investigation was carried out on the wood species cavities colonized by honeybees in Nigeria for a period of four years. 24 wood species belonging 15 families were identified. The predominant wood families used for nesting by honeybees were Fabaceae, Malvaceae and Verbenaceae accounted for 11.90%, 19.04% and 26.19% respectively with Adansonia digitata (Malvaceae) holding multiple nests. Other families include Anacardiaceae, Apocynaceae, Arecaceae, Combretaceae, Irvingiaceae, Moraceae, Myristicaceae, Ochnaceae, Rubiaceae, Rutaceae, Sapotaceae and Ulmaceae. Among individual tree species; Gmelina arborea cavities were most encountered (13.10%), followed by Vitex doniana (10.71%), Adansoni adigitata (8.33%) and Anacardium occidentals (8.33%).19 species were indigenous forest/savannah woods (trees), 1 exotic forest tree while 4 were agricultural tree crops such as palm. Results showed that honeybees significantly preferred Verbenaceae wood cavities (both living and dead). Families Apocynaceae, Malvaceae and Moraceae were preferred alive while others were preferred in dead state. The study further revealed that Nigeria honeybees have affinity for white and yellow coloured woods which makes them colour specific. Alternative cavities encountered were rock (primary rock), termite mounds and deserted rodent and soldier ants’ burrows. This study has therefore provided the crucial information required for the sustainable management of genetic bee’s resource. Finally, the availability status of the preferred wood species, ecological significance of honeybees as well as its conservation through the provision of desirable cavities deserves more attention than ever before.

Impact of Smartcard constraints on DBMS[Full-Text ] Laxmi Joshi, Nisreen AlzahraniSmartcards are the most secure portable computing device today. The first smartcard was developed by BULL for the French banking system. They have been used successfully in applications involving money, proprietary and personal data (such as banking, healthcare, insurance, etc.). Electronic ticketing in public transportation based on smart cards is gaining momentum worldwide. It is widely recognized that a smart card system can deliver benefits to both passengers and operators, but due to its complexity, implementation can come at a considerable cost. As smartcards get more powerful (with 32 bit CPU and more than 1 MB of stable memory in the next versions) and become multi-application, the need for database management arises. However, smartcards have severe hardware limitations (very slow write, very little RAM, constrained stable memory, no autonomy, etc.) which make traditional database technology irrelevant. The major problem is scaling down database techniques so they perform well under these limitations. In this paper, we give an in-depth analysis of this problem and propose a PicoDBMS solution based on highly compact data structures and query execution without RAM. We show the effectiveness of our techniques through performance evaluation.
