Traffic-Aware Design of a High-Speed FPGA using Network Intrusion Detection System
Ravi D. Bhadja, Prof. N. M. Wagdarikar
Abstract: Network Intrusion Detection Systems (NIDS) are critical network security tools that help protect distributed computer installation from malicious users software-based NIDS architectures are becoming strained as network data rates increase and attacks intensify in volume and complexity. Now a days, researchers have proposed using FPGAs to perform the computationally-intensive components of a NIDS. Here, we present the next logical step in NIDS architecture: the integration of network interface hardware and packet analysis hardware into a single FPGA chip. This integration permits better customization of the NIDS as well as a more flexible foundation for network security operation. To demonstrate the benefits of this technique, we have implemented a complete NIDS in a Xilinx Vertex II/Pro FPGA that performs in-line packet filtering on multiple Gigabit Ethernet links using rules from the Snort attack database.
Keywords: FPGA, Network Intrusion Detection System, in-line packet filtering.

Positive Feedback Adiabatic Logic for Power-Gating in Asynchronous Circuits
Rasneen Kombathiyil, Prithviraj A
Abstract: Power gating is used to shut down certain power domains in a chip while leaving others active. Power shutdown can significantly reduce leakage power. In this project presents an asynchronous fine-grain power-gated logic (AFPL). AFPL circuit is consists of efficient charge recovery logic (ECRL) gates and a handshake controller. ECRL gates get power and become active only when performing useful computations and thus them helps to have negligible leakage power dissipation. In the AFPL circuit, with the incorporation of the partial charge reuse (PCR) mechanism, reducing the energy dissipation by reusing the part of the charge on the output nodes of one ECRL gate which is entering the discharge phase to charge the output nodes of another ECRL gate about to evaluate. So, PCR helps to reduce the power consumption. The C*-element in AFPL-PCR offers that if its outputs are no longer required, an ECRL gate can achieve early discharging without waiting for the next empty token to arrive at this stage. Hence, AFPL-PCR reduces delay than AFPL without PCR. AFPL-PCR also reduces area than AFPL without PCR. In the proposed method, positive feedback adiabatic logic (PFAL) gates are using instead of ECRL gates in order to reduce power dissipation and implementation of carry select adder (CSA) instead of kogge stone adder(KSA) helps to increase the speed.

Design And Simulation of Multi Input DC-DC Buck Converter for Integrated Renewable Energy Generated System using Fuzzy Controller
Umesha S R, Shri Harsha J, Capt. L Sanjeev Kumar, Madhu K
Abstract: The objective of this paper is to propose a Multi-input power converter for the hybrid system in order to simplify the power system and reduce the cost. Renewable energy technologies offers clean, abundant energy gathered from self-renewing resources such as the sun, wind etc. As the power demand increases, power failure also increases. So, renewable energy sources can be used to provide constant loads. A new converter topology for hybrid wind/photovoltaic energy system is proposed. Hybridizing solar and wind power sources provide a realistic form of power generation. The topology uses a fusion of Buck converters. This configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the energy sources. Simulation is carried out in MATLAB/ SIMULINK software and the results of the Buck converter and the hybridized converter are presented.
Keywords: Renewable energy, Buck converter, Fuzzy controller.

Control System Design of Precision Antenna Positioner
Sharon Shobitha O, K L Ratnakar
Abstract: Antenna positioners usually used for dynamic tracking and telemetry data purpose, such as data from missiles or aircraft. Hence control system design using DC servomotor a PID controller and a gear box for loop stabilization for both azimuth and elevation has been carried out. And their respective frequency response and time response will be used for the design purpose. Certain non-linearity such as wind load is superimposed in the model to verify the design and evaluate the performance using MATLAB software.
Keywords: Antenna positioner, DC servomotor, PID controller.
