As of late, the web is turning into an imperative occasion data supplier and storehouse because of its continuous, open, and dynamic highlights. In this paper, web assets based states recognizing calculation of an occasion is created to tell the general population of a crisis occasion unmistakably and help the social gathering or government process the crisis occasions adequately. The connection among web and crisis occasions is first presented, which is the establishment of utilizing web assets to identify the highly sensitive.....

ABSTRACT: Re-appropriating information to an untouchable authoritative control, as is done in cloud dealing with, offers move to security concerns. The information arrangement may occur in perspective on assaults by different clients and focus focuses inside the cloud. In this way, high safety efforts are required to ensure information inside the cloud. Notwithstanding, the utilized security framework should besides consider the improvement of the information recovery time. In this paper, we propose Division and Replication of Data in the Cloud for Optimal Performance and Security (DROPS) those outright philosophies the security and execution issues. In the DROPS framework, we separate a file into pieces, and mirror the divided information over the cloud focus focuses. The majority of the inside point's stores just a solitary zone of a specific information record that guarantees that paying....

ABSTRACT: In electronic applications, a synchronous relationship between the signals needs to be preserved for that phase measurement is required. In a Traditional electronic systems, the time measurement system is designed by using classical mixed signal approach. But it causes uncertainty in phase relationship between the recovered signals. To avoid this uncertainty, minute phase shift change register and phase measurement logic core is designed inside an FPGA with high resolution and precision in the range of few Pico seconds. The working principle present in the proposed system is systematic sampling, here subsamples are accumulated over the phase detector signal. The newly designed logic core can operate over a wide range of digital clock frequencies, ranging from a few kilohertz to the maximum frequency that is supported within the FPGA fabric. The Proposed System Implemented using Verilog HDL and Simulated by Model sim6.4 c and Synthesized by Xilinx tool. The proposed system implemented in FPGA Spartan 3 XC3S 200 TQ-144.

ABSTRACT: The objective of proposed system is to design the weighted based cell segmentation algorithm for multiple scan-chains BIST in order to reduce the average power consumption during the scan in of new test vectors, and to reduce the test application time. The technique is based on selecting the best group of cells to be connected in the same scan-chain. This group of cells should have the same or very close weight of logic 1's and 0's that will be optimal to get the highest fault coverage in a specified test length. Then each scan-chain input will be connected to an output of a combinational circuit located after the Linear Feedback Shift Register (LFSR) that will generate biased test vectors according to the optimal weight of this segment of cells in the scan-chain. Thus, increasing the fault coverage and smoothing the applied test patterns will reduce the power consumption. The System is designed by using Verilog HDL and Simulation will be done through Modelsim 6.4 c. Finally the Synthesis will be done by means of using Xilinx FPGA with the model of Spartan 3 XC3S 200 TQ-144.

ABSTRACT: A coupled line narrowband filter with second harmonic suppression is presented. A Novel narrow bandpass filter with sharp rejection at the lower frequency is proposed using open loop resonator. The stopband characteristics of complementary circular split ring resonator (CSRR) are studied and designed to suppress the second harmonic frequency. CSRR loaded with the proposed filter for harmonic suppression is demonstrated. The CSRR is optimized to create the required bandstop characteristics without affecting the desired bandpass frequency. The proposed CSRR configuration provides a harmonic suppression at 2.8 GHz and open loop resonator resonates at 1.5 GHz to bandpass the desired frequency. Results are compared with the full wave simulation analysis and presented..

ABSTRACT: A modified hexagonal Sierpinski gasket-based fractal antenna is proposed for ultrawide-band (UWB) wireless applications. The designed antenna has miniaturized (36 48 mm2) and multiband characteristics. Two design guidelines, the partial ground plane technique and the circular annular ring patch on the substrate, are applied to improve impedance matching and radiation pattern characteristics. According to the simulation results, the proposed modi ed antenna has a re ection coefficient S11 of less than {15 dB, a linear phase of the reflection coefficient, 80% radiation efficiency, 2{4.5 dBi antenna gain, and omnidirectional radiation pattern properties over the full UWB spectrum (3.1{10.6 GHz). Simulated results obtained for this antenna show the expected good radiation behavior within the full 7.5-GHz UWB bandwidth
