The potential noise immunity of binary message extraction is investigated when white Gaussian noise or one of three Johnson's noise is acting. The informative signal detection probability by developed optimal receiving algorithm according to the criterion of the mean risk minimum is used as Indicator of noise immunity assessment. The developed algorithm has been simulated in Simulink software on conditions...
In the given scenario of computer architecture, there is a growing importance of pipeline structures. The need of the hour is to implement these pipelines more efficiently that is basically reducing their area overhead and dynamic power dissipation. Recent developments in the logic families have led to opening a portal to vast research areas in this field. In this paper we try to implement Sutherland...
Modular multiplication determines the efficiency of RSA cryptosystem as modular multiplication is core operation in RSA. The efficiency of modular multiplication can be improved by algorithmic improvement. The long operands in Montgomery modular multiplication can be added with carry save adders. Implementation of carry save adders on FPGAs require more area. This paper presents the implementation...
In this paper, AC analysis of a novel Junctionless Double Surrounding Gate MOSFET for TeraHertz applications has been investigated and the results so obtained have been compared with the performance of Junctionless Transistor (JLT). AC performance parameters such as scattering parameters (S11, S12, S21, S22), cut off frequency, Gate Capacitance, Stern Stability Factor (K) and drain currents have been...
This paper studies the Silicon Tunneling Field Effect Transistor (TFET) where p-i-n configuration of doping has been used. The device has been compared with the emerging GAA Nanowire FET for drain current characteristics. The characteristics of sub threshold region has been studied for different radii and gate lengths of the device. The surface potential of the device has also been studied along with...
This paper explains the dual workfunction tunnel field effect transistor with sifted gate over the source region that creates a condition of overlapping over source and underlapping by drain simultaneously to get the suppressed ambipolar behaviour with enhancement in ON current of the device. Overlapping over the gate enhances ON current by reduction in the tunneling barrier at source channel interface...
In this paper, we have modified the conventional lateral double diffused metal-oxide-semiconductor (LDMOS) using InGaAs known as Device1 by using trench technology with dual-gate and dual-drain structure known as Device2 and compared its performance parameters. The oxide (Al2O3) trenches are placed in the epitaxial layer at the adjacent side of the drain in which the gates are placed. The drain is...
The paper presents an approach for design of sigma-delta (ΣΔ) converters. This technique helps in finding the appropriate architecture and topology of ΣΔ modulator along with block level specifications. The design approach is implemented on the MATLAB/SIMULINK platform, that involves statistical and simulation based optimization techniques at different block levels. A 16-bit, 250 KHz signal bandwidth...
Inefficiency of human body to produce and consume insulin leads to diabetes. This diabetes over a period of time starts showing adverse effects on different organs. If it affects eye it is termed as diabetic retinopathy (DR). Earlier researchers have put forth many automated microaneurysms detection systems, but none of them can replace clinical procedure. Here, we propose an rule based system for...
Today detectability of Intellectual Property in the digital world is a major issue. And a watermarking is one of them process to secure intellectual rights of digital assets. In our paper we propose a method to insert multiple watermark in spatial and frequency domain to make our assets secure and undetectable by dividing our host image into two regions, called region-A and region-B. In a region-A,...
Multi-Robot system became an important research area in the Robotics and Artificial Intelligence. In the presence of obstacles, uncertainty and incomplete information Multi-Robot system is used to accomplish the task in more efficient way as compared to single robot system. Navigation of robots in its surrounding is essential to avoid unacceptable situation such as avoiding obstacles, trajectory planning...
The multi robots search the optimal path to explore the environment with minimum time and lesser number of turns in area exploration. An efficient exploration strategy and coordination method could enhance autonomy and performance of multirobot systems. The hybrid approach is applied to coordinate the entire robots. The technique i. e A*, D*, RRT etc is apply to explore the environment by avoiding...
Lately, modern applications like information retrieval, semantic scene classification, music categorization and functional genomics classification highly require multi label classification. A rule mining algorithm apriori is widely used for rule generation. But Apriori is used many times on categorical data, it is seldom used for numerical data. This leads to an idea that with proper data pre-processing,...
For S-Band wavelength division multiplexing (WDM) systems Silica based Thulium doped fiber amplifier (TDFA) is a main amplifying media. But the gain provided by TDFA alone is low and not flat in entire S-Band. In this paper, Raman amplifier in hybrid configuration with TDFA has been used to flatten the gain. The gain curves for the TDFA alone are analyzed and optimized for TDFA length and Thulium...
Document workflows, which plays a major role in enterprise business process automation, are dynamic and prone to be changed over time. Assuring the provenance of these workflows is important when comes to quality, long term preservation, forensics and regulatory compliance. This research introduces a Provenance Framework for collecting workflow provenance data, storing them in documents as metadata...
Over the past few years, there has been a rapid growth in the use of wireless networks. The Network name and the MAC address are the only available network identifiers by IEEE 802.11 convention by which a device can be connected to a wireless network access point. The widespread practice of the wireless network in public realm gave rise to the most provocative security menace known as Evil Twin attack...
These days users can easily store and share their data with each other using the cloud technology. Large numbers of users are not assured about integrity of their data by the reason of threats to security in a cloud. Many mechanisms are proposed and being used to verify the integrity or the correctness of single owner shared data. They suggest attaching signatures to the data. Proposed system will...
One of the critical quality of service (QoS) parameter that needs consideration in any wireless sensor network (WSN) design is network area coverage which signifies the efficiency with which the network area can be covered by the deployed network. Node sensing models are used to predict the coverage fraction percentage for a given number of sensor nodes in a predetermined network area. Alternatively,...
M-Learning software development is a complex process, which require judicious handling of requirements during elicitation, analysis, specification, prioritization, and finally application development. This article establishes four basic requirements such as Mobile-computing Infrastructure, Instructional design and learning design, Human-mobile Interaction, Evolution of Learning content and Software...
A lot of research is done on the impact of website design on site's performance. It includes use of CSS, applets, Ajax, etc. for improving the performance. However, interconnectivity between pages through hyperlinks and its impact on website performance and website structure is little explored. This aspect of a website design is explored in this paper. This brings out the time required to move from...
