Abstract

This research investigates a new Deep Q-Network (DQN) based approach to manage Dynamic Voltage Frequency Scaling (DVFS) on a multiprocessor architecture, such that it would guarantee the balance between energy consumption minimization and application feasibility. This paper also addresses software periodic real time applications with time constraints. The proposed DQN formulation operates in two steps: on offline and on online configuration. It calculates the optimal number of activated homogenous cores and their frequency and reconfigures the platform with these parameters. We perform an experimental investigation on different parameters in a simulation environment executing periodic tasks that are generated randomly with different system charge. The results suggest that the proposed method reduces energy upto CC-EDF and Static-EDF and guarantees schedulability test when compared to state of the art feedback that addresses the same applications.

Abstract

Agriculture provides a significant economical contribution to Asian countries. Conventional methods used in agriculture require much human labor and energy consumption. An ideal irrigation method for all weather conditions, soil structures, and a variety of crop cultures are needed because of the lack of adequate knowledge in the advancement of technology in rural areas. The aim of this work is to develop an agricultural field monitoring system using embedded system to provide a novel approach to automatic agricultural field monitoring. Here, the proposed work would be developed and implemented by using of temperature, humidity and rain detector sensors embedded with a micro - controller. An AVR micro - controller would be used here and the program would be written in ‘C’ using the ATMEL Studio Integrated Development Environment. The method of this developmental work required calibration of the sensors and interfacing the AVR with an output pump for irrigation purposes. As a result of using this system, farmers are able to evaluate harvest conditions. Practical implications of using this system would be to reduce unwanted usage of water whilst allowing the proper yield of harvest as well as reducing human labor.

Abstract

A nano-communication system has been developed using Quantum-dot Cellular Automata (QCA). Complementary Metal Oxide Semiconductor (CMOS) is dominant technology in manufacturing of VLSI and it has some problems with scaling in size. Semiconductor industry is looking for emerging technology to replace the CMOS technology. QCA has the advantage of ultra low power consumption, high clock rate. Nanoscale communication systems are used in computer, electronic devices, mobile phones, etc. QCA devices are designed by carefully selecting the placement of QCA cells and the timing of their tunnelling barriers are raised and lowered. By improving this communication system, signal distribution can be increased. The design of QCA is implemented using AND gate, OR gate, NOR gate, etc. The main objective of the study is to provide fast processing and energy saving approach for communication systems. Nano communication architecture with the proposed circuits demonstrates the efficiency of this design. In this paper a simple XOR gate and novel XOR gate design are shown using QCA. The results of simple XOR and novel XOR is compared in terms of delay, area and time. The active area of QCA research involves the design and verification of complex devices composed of fundamental QCA gates. Furthermore, the bit-error coverage in nano communication was detected. Using these gate level sample, it is possible to develop high combinational circuits for achieving updated technology.

Abstract

Nowadays, the lifestyle of human being is becoming smarter due to smart electronics equipments for personal as well as domestic applications. The medical field is also powered by the use of advanced technologies in hospitals. Ambulances play a significant role to transport patients from home to hospital or from one hospital to other hospital. At the time of transportation of the patients, ambulances face many critical situations like heavy traffic, traffic signals, bad road including condition potholes, etc. Moreover, the patient in the ambulance bears the roads conditions like up and down and the vibrations of ambulance. Considering such facts, it is proposed to design the smart stretcher. The aim of present research work was to reduce the effect of potholes on roads, road structure and vibrations of ambulance on a patient traveling on a stretcher in a typical ambulance. Vibrations are sensed by a smart sensor and the electronic system is designed to adjust stretcher stand smoothly, hence the effect of potholes on roads, vibrations of ambulances are removed and it becomes easy for healthcare team to transport the patient. The electronic system consist of signal processing and actuators. The signal processing unit processed the sensed data from signal and according to that the output signal is produced to actuator. On implementation of the system, it is observed that the proposed system works satisfactorily.

Abstract

The trends of electronic devices applications are changes with the evolutionary change in the electronics technology. The field of embedded technology is growing with advanced microcontrollers. Due to this, electronic system is widely used in different sectors for monitoring and controlling. On observation, it is found that controlling railway gate crossing is one of the most important concept and it is proposed to develop and deploy the advanced microcontroller for the same. Hence, the literature survey has been carried out and proposed to deploy advance microcontroller of PIC family to develop a prototype for the present system for monitoring and controlling the railway gate. For this the IR sensor is deployed to sense the position of the train and corresponding signal is processed by microcontroller according to the user firmware to generate control action of closing or opening the railway crossing gate. To cater the need of mechanical movement, DC motor is deployed in the proposed system. On investigation of the deployment of to prototype for practical purpose, it is observed that the system works successfully with high reliability.
