Hexapod robots have attracted considerable attention for several decades. Many studies have been carried out in research centers, universities and industries. This project involves the construction and working of small scale Hexapod robot. The Hexapod robot is a small, inexpensive, six-legged robot that is intended to replace huge and heavy robotic systems, containing solenoids and servo motors. The first phase of the project involves the design and construction of the structure of Hexapod. Plastic was used for the construction of body and a Nitinol actuator wire was used to drive the Hexapod’s legs. Nitinol actuator wire acts as a muscle for each of the legs, providing a means of walking for the robot. With its unique ability to contract on demand, Muscle Wire (or more generically, shape memory actuator wire) presents many intriguing possibilities for robotics. The final phase involves the Hexapod interfacing with Arduino to achieve the proper locomotion of the Hexapod. In particular, the proposed design procedure takes into account the main features, such as mechanical structure and leg configuration, actuating and driving systems, payload, motion conditions, and walking gait. It was found that compact, and lightweight Hexapod robot shows promise for use in space, medical, and other macro-robotic applications. Read More Read Less

In this paper, a .net based ontology editor has been proposed. Despite the growing interest in ontology engineering, a review of current literature reveals that most of the developments have been mainly concentrated on open source platforms. The feedback obtained from .net developers show their disappointment over current progress in the domain of semantic web and raises the need for urgent response for catering to current demands. Realizing this research gap, this paper proposed a .net based tool for ontology development and editing (TODE). Based on the developer’s feedback, it has been identified that visualization and query management are one of the most important demands of .net semantic web community. Therefore, TODE provides integrated support for these features. The evaluation of proposed tool has been performed by different usability experts, which concluded that TODE provides a convenient approach for ontology development to end-users. Read More Read Less

The traditional way for consumer to purchase a service or an item in a shop is by presenting their –physical- credit card on a point of sale (POS) device, which is called as Card Present (CP) transaction. Motivated by the growth of Internet and Smartphones, e-commerce became a reasonable alternative for timesaving purchasing activities. Significant growth in the e-commerce market has been observed through the world especially in the recent years. Remote transactions where the customer does not physically present her credit or debit card during payment are termed Card Not Present (CNP) transactions. CNP includes mail order, telephone and internet transactions. The main advantage of CNP transaction is easying the customer’s shopping experience, since the customer can buy anytime and anywhere without the need to physically present the payment card. In order to maximize the efficiency of CNP transactions, a payment facilitator is needed to sponsor retailers. It frees retailers from the need to perform the administrative procedures necessary with the acquirer. The aim of this research study is to identify the challenges and risks to developing a secure methodology to provide secure CNP-based transactions with a payment facilitator. We analyse and use the requirements imposed by regulators, identify detailed security requirements for a mobile payment system, and develop a roadmap for developing a secure methodology for mobile payment transactions.
