Big Data is spreading vastly in the industry. Most of the industries want to have the records of not only the work they do but also are eager to know the taste of the consumer. Big Data is becoming relative to almost all aspects of human activity from just recording events to research, design, production and digital services or products delivery to the final consumer. In this work, application of...
Due to the requirement of high speed applications, power utilities have come out to supply data communication over power lines to the customer. In this paper, we examine a single user multi-branch power line communication (PLC) system with binary phase-shift keying (BPSK) data and diversity combining schemes. The key idea behind this is to study the performance of a multiple wire based physical layer...
Present communication deals with the year round performance evaluation of thin film solar photovoltaic module based on energetic and exergetic approaches for a typical climatic zone in north India. Three different efficiencies including energy, power conversion and exergy have been evaluated and plotted against time for hourly solar radiation. The exergy and power conversion efficiencies for the month...
A new circuit technique is proposed in this paper for reducing both the subthreshold and gate oxide leakage power in the domino logic circuits. Three high-Vt sleep transistors are added to the standard domino logic circuit to place the circuit into low leakage state. Proposed circuit is evaluated at 110°C and 25°C. At 110°C, proposed circuit reduces leakage power consumption by up to 63%, and at 25°C,...
This paper reports the experimental study on the frequency and stretch dependency of permittivity of a commercially available acrylic dielectric elastomer (VHB 4910) film. The procedure for preparing samples with different thickness using in-house developed uniaxially stretching device is described. Copper tapes are implanted on two opposite sides of a stretched elastomer film and permittivity of...
A circuit technique is proposed in this paper for simultaneously reducing both subthreshold and gate-oxide leakage power consumption at high and low temperatures in footed domino logic circuits. A high Vt pMOS pull-up technique with feedback control utilizing both multiple-Vt and multiple Tox is added between the footer node and dynamic node to place footed domino logic circuit into a low leakage...
In this paper we overview the different types of DoS attacks, present recent DoS defense methods as published in technical papers, and propose a novel approach to counter DoS. Based on common defense principles and taking into account the different types of DoS attacks, we survey defense methods and propose a simple-to-integrate DoS victim based defense method which aims at mitigating an attack's...
An identity-based signature scheme allows any pair of users to communicate securely and to verify each other's signatures without exchanging public key certificates. For achieving both confidentiality and authenticity simultaneously, signcryption schemes are used. This paper puts forward a new efficient construction for signcryption scheme which is based on inverse bilinear Diffie Hellman problem...
Identification of fault-prone or not fault-prone modules is very essential to improve the reliability and quality of a software system. Once modules are categorized as fault-prone or not fault-prone, test effort are allocated accordingly. Testing effort and efficiency are primary concern and can be optimized by prediction and ranking of fault-prone modules. This paper discusses a new model for prediction...
For a Mobile Robot to navigate in the Human-Centered environment without imposing alien like impression by its motion, it should be able to reason about various criteria ranging from clearance, environment structure, unknown objects, social conventions, proximity constraints, presence of an individual or group of peoples, etc. Also the robot should neither be over-reactive nor be simple wait and move...
Interestingly Humans are able to maintain rough estimations of visibility, reachability and other capabilities of not only themselves but of the person they are interacting with. Studies in neuroscience and psychology suggest that from the age of 12-15 months children start to understand the occlusion of others line-of-sight and from the age of 3 years they start to develop the ability, termed as...
