Author Name:E. Kiran Mahesh,L.Bramarambha , M.C.Veera Sekhar , M.Lakshmikar Reddy , M.Saravanan
Synopsis:
Current technology is changing day by day, it is important for every nation to protect themselves from intruders. In this paper, the authors have developed a low cost robotic device capable of accurately and safely targeting and firing of an intruders who enters into a restricted. The main objective of this robotic system is to provide a best security system for “Border Security Force (BSF)” in order to eliminate the terrorists, also for star hotels, shopping malls, jewellery show rooms, etc. Where, there can be threat from intruders or terrorists. Since, human life is always precious, these robots are the replacement of fighters against terrorist in war areas. Firing of the targets takes place by the gun which can be automatically moved towards the target based on the proximity sensor arranged in some random places. This movement of the gun can be done automatically and manually.

Title:Diagnosis and Analysis of Heart Rate Using Pulse Sensor
Author Name:S.Priyadharshini 
Synopsis:
This paper deals with the diagnosis and analysis of heart rate using Pulse sensor. The pulse sensor uses the optical Methodology to detect the blood flow through the index finger and offers the advantage of portability. The principle of Pulse sensor is that a certain amount of light energy from infrared is absorbed by blood cells and the remaining amount of light is transmitted to the photodiode. Based on the amount of light transmitted, the flow of blood can be calculated, which is directly related to pulse rate. A PIC (Programmable Interface Controller) microcontroller (PIC16F877A) is programmed to count the pulse and to display the heart rate digitally on an LCD (Liquid Crystal Display). The important feature of this paper is the use of Fast Fourier Transform (FFT), to analyze the heart rate using the pulse signal and to diagnose heart related diseases using MATLAB tool. The performance of this device was compared with manual pulse measurement of heartbeat and ECG (Electrocardiography) signal represented on an oscilloscope. Finally, the heart related disease can be diagnosed using the obtained result after the analysis of pulse signal.

Title:Development of a Performance Evaluation Tool for Hybrid Vehicles System Design
Author Name:Kary Thanapalan , Jonathan Williams
Synopsis:
This paper discusses a simulation and modelling tool developed at the University of South Wales (USW). This tool has been  developed within the MATLAB/SimulinkTM platform for flexibility and functionality. It is able to deal with any dynamic behaviour and the various elements of a Hybrid Electric Vehicle (HEV) as well as the dynamics in terms of fuel usage of the vehicle. The simulation tool comprises a set of component models, which may be re-parameterized to represent different systems assembled in simulink for a particular vehicle configuration. This paper also discusses the methodology for vehicle drive train design, energy management strategies, performance analysis and controller design using the simulation tool. It can be used for control analysis, configuration setup and analysis for better energy management strategies. Design of three USW-HEVs (University of South Wales-Hybrid Electric Vehicle) is discussed to illustrate the capabilities of the simulation tool. The results shows that the simulation tool can accurately represent the dynamic behaviours of several variations of alternative car concepts.

Title:A Review on Automotive RADAR
Author Name:Manju James,Nisha J.S., Anoop B.N., Sanju Sebastian. R, Veeresh A G
Synopsis:
Autonomous vehicles increase safety, provide more comfort and increase the mobility of young and old alike. The automotive industry is witnessing a fast transition from partially automated driving - involving continuous human monitoring of automatic functions, to highly automated driving that require drivers monitoring only when called for. Among the various methods available for street monitoring, only radar can operate in all weather conditions, which makes it the eye of an autonomous vehicle. This paper explains the progress in automotive radar technology and mentions the possibility of integrating automotive radar with future intelligent transport system.

Review On Dielectric Resonator Antennas

Title:Review On Dielectric Resonator Antennas
Author Name:Amna Bedi And Santosh Kumar 
Synopsis:
When a dielectric resonator is not entirely enclosed by a conducting boundary, it can radiate, and so it becomes an antenna, named Dielectric Resonator Antennas (DRAs). DRAs consist of dielectric materials in its radiating patch also called as dielectric resonators (DRs) on one side of the substrate and has a ground plane (metal) on the other side. DRAs have several merits, including high radiation efficiency, flexible feed arrangement, simple geometry and compactness. There are wide applications of DRAs and it can be designed for the compactness, wide impedance, low profile, circular polarization, and for the high gain.

Title:Tuning Of Fractional Order PID Controller For Interacting Systems By Different Methods
Author Name:D.V.L.N.Sastry, B.Anil Kumar, P. Kameswara Rao And G.S.S.S.S.V.Krishna Mohan
Synopsis:
A multi tank level control system is an example of interacting systems. In this paper, the authors considered two first order systems connected in series, one rectangular tank which has inflow of liquid into the tank and out flow. The outflow of first tank is the inflow for second tank through a control valve. The control System is intended to maintain the level of liquid in the second tank at some predefined value irrespective of changes of inflow to the first tank. Fractional Order PID (FOPID) controller is a powerful controllers used in process industries to regulate and control process variables. The errors of the process variables are minimized proportionally, integrally and derivatively. Fractional Order PID controller gives better results for changes in set point and disturbance rejections. The change in inflow or changes in predefined values are treated as disturbances to the process. According to these disturbances, they need to implement better tuning algorithms to Fractional Order PID controllers. In this paper, they implemented different Fractional Order PID control algorithms on a multi tank level control System and their responses are observed and also compared with Conventional PID controllers.

Title:Tracking Path Control Of Robotic Manipulators Using Radial Basis Function Neural Network
Author Name:Sheilza Jain and Anika Chhabra
Synopsis:
Robotic manipulators have been extensively used in the industrial applications such as paint spraying, welding, accurate positioning system etc. where joint angles of robotic manipulators are directed to follow some given trajectories as close as possible. Therefore, trajectory tracking problem of robotic manipulators is the most significant and fundamental task for researchers to work upon. Robotic manipulator systems are inevitably subject to structured and unstructured uncertainties resulting in imprecision of its dynamical models and it is difficult to obtain a suitable mathematical model for the robotic control scheme. Robotic manipulators are dynamically coupled, multi-inputmulti- output, non-linear and time variant complex systems. This paper presents the dynamics of two link robotic manipulator. In this paper, PID (Proportional Integral Derivative), CTC (Computed Torque Control), SMC (Sliding Mode Control) and RBFNN (Radial Basis Function Neural Network) controllers are designed and implemented to the joint position control of two link robotic manipulators for pre-defined trajectory tracking control. Simulated results for different controllers are compared to show reduction in tracking error and performance improvement of two link robotic manipulators. Tracking performance and error comparison graphs are presented to demonstrates the performance of the proposed controllers. Further, comparison between chattering of SMC and RBFNN-SMC for joint 1 and joint 2 is also shown. The simulation work is carried out in MATLAB environment.
