Parity checking is one of the extensively used approaches for error detection in conventional digital systems. This work presents a 4×4 reversible logic gate (SMS gate) integrated with parity preserving property, which produces all primitive Boolean gates. The hardware complexity in terms of total logic count of SMS gate is 6α+1β only, which found to be minimal compared to all the existing gates....
In this paper a High Speed and Low Power 4-Bit Multiplier using FinFET technology at 32nm is proposed. Comparative analysis of MOSFET based and FinFET based multiplier is done using HSPICE tool. FinFET is found to be less power consuming than MOSFET by 97%. Further optimization of FinFET based multiplier is achieved in terms of delay using sleep mode and tri mode techniques by 28% and 81% respectively.
There is a growing research interest in quantum computing because of its promise to provide significant performance speedups over classical computers at specialized tasks. While there have been many advances in building more capable, robust, and useful quantum algorithms and software, it is not clear how a scalable, high-performance, and area-efficient quantum architecture should be designed for efficient...
Community question answering (CQA) is a popular online service for people to ask and answer questions. But along with the increasing of user generating contents, the quality of answers provided by different users varies widely. So the quality of the answer caused wide attention. In this paper, we propose an answer quality prediction model to evaluate the answer quality considering both aspects of...
The paper presents design and simulation of, one of the quantum reversible gates, the Feynman gate, using the single electron threshold logic gate. One of the most emerging areas in quantum computing is the application of reversible gates in computational circuits for increasing the computational efficiency. Here the presented approach combines the advantages of the single electron threshold logic...
The design and operation of an asynchronous two-input mutual exclusion element are described in this paper. A decision-making module suitable for implementing n-way decision-making circuits is also implemented using CMOS DVCS logic.
A high speed circuit with precharged technology is described, k 32-bit ALU which employs this technology has been designed. New ALU realized about 2.5 times faster speed than that of former one which was designed by poly-cell technology, A carry-propagation delay time by the carry-lookahead and the conditional-sum was 5.0ns, which is 3.6 times faster than that of poly-cell approach. This technology...
Enrolments in North American undergraduate computer science have been booming in recent years, and many CS departments have been struggling to meet student demand. We surveyed 78 CS professors, instructors, staff, and administrators to see how the enrolment boom has been affecting their practice; and to see how departments are responding in terms of policy. We asked participants to tell us what factors...
Blockchain represents a technology for establishing a shared, immutable version of the truth between a network of participants that do not trust one another, and therefore has the potential to disrupt any financial or other industries that rely on third-parties to establish trust. In order to better understand the current ecosystem of Blockchain applications, a scalable proof-of-concept pipeline for...
A novel design of a microcontroller based I–V plotter is presented. The I–V plotter is designed using the IGBT electronic load driven with a microcontroller based algorithm. The I–V plotter is tested by obtaining the output characteristics of Photovoltaic (PV) modules in series / parallel combinations and 1 kW Fuel cell (FC). The results show that the output characteristics for both the DC generators...
Getting visa or its renewal is one of the important elements for International students studying abroad. Each and every year students need to renew their visa, to extend their studentship in order to stay in a particular country. In Malaysia, in order to process visa renewal faster, Education Malaysia Global System (EMGS) was introduced by Malaysian Government. Since the implementation of EMGS in...
A computer has become possible to operate more services by improving the performance. Therefore, there is a growing tendency to aggregate a single computer. In consequence, a virtualization technology such as VM (Virtual Machine) is receiving a lot of attention.
Voltage source inverters are essential systems in many applications. Thus, the diagnosis of the faults that could appear in these systems allows detecting, isolating, and identifying the faults. In this context the teaching of this subject is becoming very important. However, laboratory experience is fundamental in order to provide a real understanding of this subject. This paper presents a computer...
Advanced Metering Infrastructure (AMI) is an indispensable part of a Smart Grid (SG) initiative. AMI applications collect data measured by smart meters in the SG. This process may leak information about consumers. In this paper, we build an IEEE 802.11s-based SG AMI network testbed consisting of Beaglebone Black boards and investigate the performance of privacy-preserving protocols in real-life and...
Information-Centric Networking (ICN) proposals rethink the communication model around named data, in contrast with the host-centric transport view of TCP/IP. The content retrieval in ICN is natively receiver-driven, chunk-level based, multi-path forwarding and intrinsically coupled with in-network caching. To make the best use of in-network caching resources, NDN router should acquire the view of...
Content-Centric Networking (CCN) proposals rethink the communication model around named data. In-network caching and multipath routing are regarded as two fundamental features to distinguish the CCN from the current host-centric IP network. In this paper, we tackle the problem of joint collaborative caching and multipath routing in CCN. We achieve this with an online and offline combination caching...
Managing the extremely large volume of information generated by Internet-of-Things (IoT) devices, estimated to be in excess of 400 ZB per year by 2018, is going to be an increasingly relevant issue. Most of the approaches to IoT information management proposed so far, based on the collection of IoT-generated raw data for storage and processing in the Cloud, place a significant burden on both communications...
One method of alleviating the burdens of low bandwidth channel in underwater sensor networks (UWSNs) is to perform in-network processing on the collected data, which leads to efficient channel usage, improvement of the end-to-end delay, and improvement of the network lifetime. However, for applications that require large amounts of data, such as seismic monitoring, the detection and tracking of marine...
