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.
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.
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.
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.
The main purpose of using controllers in heat exchanger is to control the fluid outlet temperature to its set point. Several controllers are in use to control the set point in a heat exchanger. In tubular heat exchangers, due to the flow induced vibration resonance occurs. If the vibration is high, it can cause damages to the tubes present inside the tubular heat exchanger. To eliminate this problem, repetitive controller is used which can easily cancel out the resonance dynamics present. In this paper, design of a tubular heat exchanger and Repetitive Controller is done and the simulation results are also provided.
In this paper, Li-Fi, as the name, Light Fidelity indicates that the visible light is exploited to serve two essential functions at the same time. To serve this purpose, the aid of Light Emitting Diodes (LED) is taken into consideration. The two major functions to be rendered by visible light are illumination and communication. This technology is an eco-friendly way of transmitting data by utilizing the visible light spectrum. The main idea behind this is to switch on and off the LED at a faster rate. The rate of flickering is high such that the flickering of LED is not visible to human eyes. Meanwhile Power Line Communication can be integrated along with Li-Fi making use of power lines as the medium of communications. The utilities of home networking over power-lines can take advantage of the existing wiring infrastructure for provision of illumination cum communication. To supplement this, even devices could be controlled by transmitting commands in digital format through the visible light spectrum. This paper envisions a future where data for laptops, smart phones, and tablets is transmitted through the light in a room. And security would be snap – if you can't see the light, you can't access the data. Also Li -Fi can be put into use, wherein electromagnetic waves are strictly prohibited considering the case of aircrafts in this aspect.
