In recent days it becomes very difficult task to manage security on large network and practically not possible to keep security scanner on every networks for protecting the system from illegal users. This problem can be solved with prevention systems which come in strategic role of Intrusion Prevention Systems that is taken as extended and enhanced version of IDS. By using this system we can upgrade...
This paper presents the theory of a microwave band reject filter (BRF) performance when the input signal to be rejected is accompanied by an adjacent channel frequency-modulated interference. The BRF is designed in the X-band at 10 GHz. The 3-dB bandwidth of the BRF is calculated to be 1.485 GHz. We have calculated the FM interference power of the output of the BRF as a function of input interference...
RSSI method is used to measure the distance between beacon nodes and unknown node. This technique is not more relevant because the radio frequency (RF) signals are mostly affected with the noise available in the environment. Therefore, the accurate distance evaluation cannot possible between the known nodes and unknown nodes. RSSI method is having many accuracy challenges which need improvements....
In this paper, we propose a method for detecting variations in the Pulse Rate (PR) of infants undergoing the Hammersmith Infant Neurological Examinations (HINE) using video data. As in every other medical examination the measurement of the PR is critical to underpin the physiological state of living beings. During HINE, measuring the infant's PR is important as its variations against physical conditions,...
We discuss a new method for the measurement of electric (E) fields that will lead to a self-calibrating, direct SI-traceable E-field probe. The technique is based on radio frequency E-field interactions with alkali atoms placed in glass cells. After we present the concept of this approach and present some experimental data to show its validity, we give a discussion of the different types of uncertainties...
Distributed Denial of service (DDoS) attack is an attempt to prevent the legitimate users from using services provided by service providers. This is done through flooding their server with the unnecessary traffic. These attacks are performed on some prestigious web sites like Yahoo, Amazon and on various cloud service providers. The severity of the attack is very high, as a result the server goes...
In recent work we have demonstrated a fundamentally new approach for electric (E) field measurements (Holloway et al., IEEE Trans on AP 12, 6169–6182, 2014; Sedlacek et al., Nature Phys, 8, 819, 2012). The new approach is based on the interaction of RF-fields with Rydberg atoms, where alkali atoms are excited optically to Rydberg states and the applied RF-field alters the resonant state of the atoms...
Maritime norms set to reduce pollution, search for environmental friendly power source and the requirement of increased underwater endurance have led to the remarkable research on Fuel Cell Power Sources (FCPS) for marine applications. FCPS are relatively clean and efficient energy sources. Fuels cells are being used for various marine applications such as on board naval ships, boats and even submersibles...
This paper describes a comparative study of sensitivity and non-linearity of conventional and bossed diaphragm piezoresistive pressure sensor along with a performance enhanced design. The proposed structures take into consideration corner compensation to avoid distortion of the mesa structure during fabrication of bossed diaphragm structure using wet bulk micromachining. Optimum piezoresistors locations...
Pressure microsensors are very frequently used for applications encompassing a wide range of operating pressure ranges. However, it is possible to use the same pressure sensor for different operating ranges (in a limited range) with satisfactory performance. In this work, we report the possibility of using a single sensor for different pressure ranges. Operating the sensor at a lower pressure range...
Due to very fast growth of information in the last few decades, getting precise information in real time is becoming increasingly difficult. Search engines such as Google and Yahoo are helping in finding the information but the information provided by them are in the form of documents which consumes a lot of time of the user. Question Answering Systems have emerged as a good alternative to search...
The communication between the grid control center (GCC) to aggregator and aggregator to Electrical Vehicles (EV) is very important in order to support the grid requirements and meet the load demand in a short duration of time. The aggregator sends the power requirement information to EVs and EVs have to receive this information irrespective of either being parked or moving. The EVs which have received...
Newborn swapping, missing, mixing, and illegal adoption is a global challenge and to resolve this emerging issue very less research has been done. Most of the biometric systems are developed for adults and extremely few of them address the difficulty of newborn recognition. As they are the highly non cooperative users of biometrics the ear of newborn may be a perfect source of data for passive identification...
Remote Sensing is widely used for mapping of land cover and land use. Classification of image satellites is also done by using these mapping. In this paper the classifier proposed is the Probabilistic based Neural Network developed using MATLAB. The data for image classification is acquired over various parts of Mumbai region which is LISS-III. Probabilistic based neural network is a supervised classification...
An Inspection is a study of methods and techniques that can be suitably employed in practical applications. In this paper, a new activity is proposed and analysis framework to facilitate the inspection of a cylindrical object using coordinate conversion technique along with pattern matching which is again verified by machine vision technique in which maximum efficiency can be achieved. By using LABVIEW...
Correct discrimination of essential tremor from Parkinson's tremor is a major problem in clinical neurology as minor differences in the tremor patterns are hard to distinguish. Mathematical analysis of tremor signals recorded non-invasively has been widely accepted for tremor differentiation. However, classification of tremor signals collected from electromyograph or accelerometer, based on time and...
Clock gating is an effective technique for minimizing dynamic power in sequential circuits. This paper aims at reducing the power of a dual port register memory by removing the unwanted switching activity on a major portion of the clock network using clock gating. To realize this, two register based Random Access Memories (RAMs) have been designed, one with clock gating and the other without clock...
This paper proposes and analyses a method that will increase the number of voltage level of any existing topology, only thing is load should be connected across H-bridges. In order to verify the proposed cell, various existing topologies have been simulated and analyzed. The purpose of the circuit proposed is to reduce the use of IGBT switches and hence improving the Total Harmonic Distortion.
UPS inverters typically employ low pass, LC filters in the output stage for proper voltage regulation. The present paper explores a step by step comparative analysis by using an active damping control structure to provide enhancement in UPS performance without any increase in the value of resistance of LC filter. Simulation results in MATLAB environment are presented to confirm upon the point.
Wireless ad-hoc networks (WANET) have recently emerged as a premier research topic due to its infrastructure-less and dynamic natures. Topologies of this network can changes very frequently due to its dynamic nature. The node of this network fitted with limited capacity battery which is major problem in real-time operation. The present paper proposes a routing protocol; named Fuzzy based Intelligent...
