Phishing is a criminal mechanism employing both social engineering and technical subterfuge to steal consumers’ personal identity data and financial account credentials. Social engineering schemes use spoofed e-mails purporting to be from legitimate businesses and agencies to lead consumers to counterfeit websites designed to trick recipients into divulging financial data such as usernames and passwords. Technical subterfuge schemes plant crimeware onto PCs to steal credentials directly, often using systems to intercept consumers online account user names and passwords and to corrupt local navigational infrastructures to misdirect consumers to counterfeit websites (or authentic websites through phisher controlled proxies used to monitor and intercept consumers’ keystrokes). Web sites that are frequently spoofed by phishers include PayPal, eBay, MSN, Yahoo, BestBuy etc. Some of the criminals behind phishing scams have even gone so far as to create websites that appear to be operated by government agencies. According to latest phishing reports submitted to APWG of 26,402 in March 2011 was down 35 percent from the all-time high of 40,621 in August, 2009.[1]Though many agencies, personnel’s working for combatting this problem new techniques have been developed to outsmart them. This paper aims to discuss latest phishing techniques, motivation, causes of vulnerability of systems in detail. This analysis aims to help users & organization to avoid being victims and to take primary preventive measures.

Today, the existence of natural elements such as sky, mountain, jungles, coastal area, untouched natural zones, water, and deserts have brought many meaningful ideas to the minds of the urban designers and city dwellers. The importance of these elements lies in the fact that they are free from tension, busyness and mental pressure, which are the gifts of civilization to human being. Dez River can be a potential tourism attractor to entertain people and can decrease the stress of living in a city. It, also, can have a beautiful view and boost the quality of life. This study aims to recognize the river significance in urban structure and its role in identifying the sustainable landscape and urban ecological corridor, which surrounds the city. It also attempts to present the principles which should be considered in planning the riverbank wall, by examining this wall near Dez River. By investigating urban structure and river role in forming and developing the future view of the city, the river boundaries, as the urban green belt and respiratory corridor, are determined. Therefore, after presenting some definitions related to the subject of the study, we discussed the sustainable design and its factors for river wall. Also, by introducing such factors, we suggested some approaches to treat Dez River and to achieve an organic and expandable structure in order to build the green corridor on the riverbank and to turn the corridor into a dynamic and live center for the city.

Polybutylene Terephthalate (PBT) / Polyethylene Terephthalate (PET) nanotube composite blend was fabricated using melt blending technique in a twin extruder. The blend composition was optimized at PBT-PET weight ratio of 80-20. The effect of incorporation of MWCNT on the mechanical, electrical, thermal and morphological properties of the nanotube composites blend has been investigated. Mechanical properties show marginal improvement in impact strength, but considerable improvement in tensile strength and flexural strength. Changes in electrical properties observed. Increase in crystallisation temperature noted from DSC thermograms. DMA add the evidence for DSC and mechanical results. PBT - PET blend with CNT exhibited featureless XRD indicative of exfoliated structure. TEM micrographs also confirmed the same that the CNT has exfoliated into individual tubes.

The proposed project is to implement a novel idea in Sensor networks. Normally Sensor networks are used to sense environment and collect data. Security in such networks is a big challenge. The first challenges of security in sensor networks lie in the conflicting interest between minimizing resource constraints and maximizing security. An implementation of operating system may reduce the risk level of handling secure data but sensor networks also introduce severe resource constraints due to their lack of data storage and power. Thus we employ a hardware cryptographic unit with low power consumption. The working memory of a sensor node is insufficient to even hold the variables (of sufficient length to ensure security) that are required in asymmetric cryptographic algorithms. A symmetrical key crypto security system will be less adequate to handle the modern secure threats, due to that a much complex asymmetric crypto system called elliptic curve cryptography is designed with various optimizing units(ex: pipeline, scheduling) to achieve greater security and to consume much power with reduced resources constraint.

The aim of the paper is to produce faster results when pipelining above the inner most loop. The concept of outerloop pipelining is tested here with Fast Fourier Transform. Reduction in the number of cycles spent flushing and filling the pipeline and the potential for data reuse is another advantage in the outerloop pipelining. In this work we extend and adapt the existing SSP approach to better suit the generation of schedules for hardware, specifically FPGAs. We also introduce a search scheme to find the shortest schedule available within the pipelining framework to maximize the gains in pipelining above the innermost loop. The hardware compilers apply loop pipelining to increase the parallelism achieved, but pipelining is restricted to the only innermost level in nested loop. In this work we extend and adapt an existing outer loop pipelining approach known as Single Dimension Software Pipelining to generate schedules for FPGA hardware coprocessors. Each loop level in nine test loops is pipelined and the schedules are implemented in VHDL. Across the nine test loops we achieve acceleration over the innermost loop solution of up to 7 times, with a mean speedup of 3.2 times. The results suggest that inclusion of outer loop pipelining in future hardware compilers may be worthwhile as it can allow significantly improved results to be achieved at the cost of a small increase in compile time.

The purpose of the study was to predict the playing ability in Kabaddi from selected Anthropometrical, Physical, physiological and psychological variables among College level Players. One hundred and twenty six male inter collegiate Kabaddi players were randomly selected from various colleges in Tamilnadu state, India and their age ranged between 18 and 28 years. The subjects had past playing experience of at least three years in Kabaddi and only those who represented their respective college teams were taken as subjects. A series of anthropometrical measurements was carried out on each participant. These included Standing height measured by Stadiometer; Body weight measured by weighing machine, Two Length measurements - Arm length, Leg length, measured by Lufkin Anthropometric Tape. The data were collected by following standard testing protocol of International Society for the Advancement of Kinanthropometry. Physical fitness components were measured by the following tests. Speed were assessed by 50 meter dash, Flexibility assessed by Sit and reach test, Leg explosive strength assessed by Standing broad jump, Muscular power assessed by Modified sit – ups and Muscular endurance assessed by 2.4 km run. The Physiological parameters namely Resting heart rate by Digitalized heart rate monitor, Peak expiratory flow rate was assessed by Peak flow meter and Breath holding time was assessed by Manual nose clip method.

The Indian aviation industry is one of the fastest growing aviation industries in the world. After LPG policy, the government's open sky policy has led to many overseas players entering the market and the industry has been growing both in terms of players and number of aircrafts. Today, private airlines account for around 75 per cent share of the domestic aviation market.

Text detection and recognition in real images taken in unconstrained environments, such as street view images, remain surprisingly challenging in Computer Vision. Extraction of text and caption from images and videos is important and in great demand for video retrieval, annotation, indexing and content analysis. In this paper, we propose a text extraction algorithm using Dual Tree Complex transform. It is demonstrated that the proposed method achieved reasonable accuracy of the text extraction for moderately difficult examples.

Employee satisfaction has been defined as a function of perceived performance and expectations. It is a persons’ feeling of pleasure or disappointment resulting from comparing a products’ outcome to his/her expectations. If the performance falls short of expectations, the employee is dissatisfied and if it matches the expectations, the employee is satisfied. This research mainly deals with the satisfaction level of an employee in a organization. The research results indicate positive relationships between general employee satisfaction and growth of the company Neglecting employee satisfaction can be harmful to corporate entrepreneurship, which have been previously developed in the right direction, contributing to performance, competitive advantage, and growth. This research deals with general employee satisfaction within small scale organization. In the following sections, the theory, hypotheses, research methodologies, recommendations and results of an empirical study on a sample of firms from small scale software organization are presented.

Cancer is a hyper proliferative disorder marked by metastasis into the vital organs of the body through invasion and angiogenesis. Biodegradable nanoparticles have been used frequently as anti-cancer drug delivery vehicles due to its splendid bioavailability, better encapsulation, and control release with less toxic properties.
