Power Consumption Analysis of BCD Adder using XPower Analyzer on VIRTEX FPGA

Abstract: Adders are the integral part of any digital circuit operation. Optimization of adder’s supremacy along with its vicinity is a demanding chore. In this work an efficient BCD ADDER1 is analyzed in terms of power consumption by scaling the various parameters like voltage, frequency and load capacitance. In addition to this the focus is also given on the airflow of the device to reduce the power. Finally the power is reduced by sending different encoded data at the input. The proposed designs are hardened and implement by means of VHDL and Xilinx ISE (integrated Software Environment) 14.5 and validated using XPower targeting Virtex FPGA. Power consumption is discussed in terms of clock, signals, logic, input/ outputs and leakage. A comparative analysis has been shown at the end to validate the obtained results.

A Study of Online Co-Creation Strategies of Starbucks Using Netnography

Abstract: Inbound marketing focuses on producing relevant, audience captivating, high quality content that attracts consumers towards the online presence of a specific organization, brand or product. This study has been conducted using the online marketing research technique called netnography-a qualitative and interpretive methodology for the study of users in the virtual space. As the virtual medium presents a good medium for organization-consumer, bi-directional dialogue, companies can use the online arena for soliciting consumer views for their products, promotion mechanisms etc., hence, making these ideal tools to enable consumer participation in the co-creation strategies of organizations. Co-creation involves the consumers' participation in the creation of the core offering itself. It can occur through shared inventiveness, co-design or shared production of related goods, and can occur with customers and any other partners in the value network R. Bolton, & S. Saxena-Iyer, 2009. Co-creation occurs when the customer participates through spontaneous, discretionary behaviors that uniquely customize the service experience beyond the selection of pre-determined options. This was done by exploratory research on consumers' behavior in the online community "My Starbucks Idea", with respect to updates and responses from Starbucks and their behavior with respect to feedback and suggestions from consumers. Ideas include fresh ideas given by other consumers to Starbucks through posts and the ideas which have been implemented recently in the stores that are updated by Starbucks' employees. Starbucks behavior was seen in terms of the ratio of volume of suggestion posts by consumers and volume of ideas adopted by Starbucks. "My Starbucks Idea" involves the psychological aspects of consumer behavior which are utilized by Starbucks because the ratio of volume of suggestion posts by consumers and the volume of ideas adopted by Starbucks is remarkably high. Another reason of participation of the consumers is the social connection; it is supported by the higher volume of posts observed.

Implementation of Ciphertext Policy-Attribute Based Encryption (CP-ABE) for fine grained access control of university data

Abstract: Ciphertext Policy-Attribute Based Encryption (CP-ABE) is an emerging encryption technology to address challenges of secure data sharing. In this paper, a CP-ABE based scheme has been implemented for fine grained access control of documents in a typical university setup. The documents are encrypted with an embedded access structure and can be decrypted by only those users whose attribute values satisfy the access structure defined for the document. Experimental simulations demonstrate the capability of proposed solution in providing real time encryption/ decryption services on varying number of attributes, file sizes and types.

A Novel Differential Evolution Test Case Optimisation (DETCO) Technique for Branch Coverage Fault Detection

Abstract: Test case optimisation is an important research area of the software industry. As, testing takes so much time, effort and moreover it is very costly. So, it becomes very important for us to test the software effectively without doing so much effort. There are many techniques or nature inspired algorithm which helps us to do testing of a software effectively and one of the nature inspired algorithm is Differential Evolution Algorithm. Hence, this paper proposes a novel test case optimisation technique, i.e., differential evolution test case optimisation (DETCO). The proposed technique optimizes the test case selection and prioritization of the test cases to have comprehensive branch coverage and faults detection. Twenty test cases for a sample code have been generated. The proposed technique selects three test cases which provide complete branch coverage as well as fault detection.

Multiple user pair scheduling in TWR assisted FSO systems

Abstract: In this paper, various multiuser scheduling schemes are applied to a two-way relay (TWR) assisted multiple user pair free-space optical (FSO) communication network, when the optical beam is subjected to path loss, misalignment errors, and atmospheric turbulence. The FSO network consists of a single, half-duplex, decode-and-forward, two-way optical relay that serves multiple user pairs by employing a scheduler. Three types of schedulers based on absolute signal-to-noise ratio (SNR), normalized SNR, and selective multiuser diversity are considered. Further, the atmospheric turbulence is modeled by a recently proposed statistical model, namely the Malaga M-distribution. For the presented system and channel models, closed-form and asymptotic expressions for outage probability and bit error rate are derived. The mathematical analysis is accompanied by Monte Carlo simulations and several numerical examples to illustrate the effect of the key system parameters.
