Application of carbon nanotubes (CNT) on the computer science and electrical engineering: A review
Get PDFIn recent years, dimensions and sizes of components and parts in the computer and electronic industries have been steadily reducing, as they are now considered very tiny tools and there is always a need to store and process information stronger. Nanotubes have poor magnetic properties. If nanotubes are covered by ferromagnetic nanoparticles, their magnetic properties can be improved and they can be used in the manufacture of nanoelectronic devices in the computer and electronic industries. In addition to reviewing the structure and properties of materials made using different nanomaterials for use in the computer and electronic industries, the present paper aimed to study different applications of nanomaterials, especially carbon nanotubes, in the manufacture of electronic devices. The present study showed that the corporation of nanomaterials into electronic devices is a promising approach for future applications which can revolutionize the computer industry
Arduino controller based borewell child rescue system
Get PDFIn this paper we have proposed a system for rescuing victims of bore well accidents. The proposed system is light in weight compared to existing methods, portable easy to handle and requires lesser manpower. The system design comprises of a four leg metal stand which supports the whole mechanical assemble the stand is of low weight therefore it is easy to transport it does not requires any heavy duty cranes. This stand has a round housing which holds the DC gear motor which controls the up and down motion of a robotic arm as the arm is connected to the motors shaft with pulley through a rope or heavy duty steel cable. The robotic arm has four mechanically operated fingers which can be opened or closed using a dc motor placed on the arm itself this motor controls the arm by tightening the cables which runs over the four finger joints just like a human arm. The two motors are controlled by an Arduino based remote control module containing buttons and toggle switch with the help of this module easy control of the system is achieved. In addition to this an ultrasonic sensor and a digital camera was also incorporated to predict the victim’s location. In order to determine the feasibility of the system a prototype was designed and fabricated. The prototype consists of all mechanical and electronics setup as discussed above but in a miniature version. The prototype has a control module which consist of LCD display, motor driver IC, Arduino microcontroller, control switches, buttons and power supply unit. This is the main electronics unit which controls and coordinates the whole systems operation. The project is intended to reduce the risk involved during the child rescues operation by analysing the simulation
A compact model of transconductance and drain conductance for DMG-GC-DOT cylindrical gate MOSFET
Get PDFA compact model for dual-material gate graded-channel and dual-oxide thickness with two dielectric constant different cylindrical gate (DMG-GC-DOTTDCD) MOSFET was investigated in terms of transconductance, drain conductance and capacitance. Short channel effects are modeled with simple expressions, and incorporated into the core of the model (at the drain current). The design effectiveness of DMG-GC-DOTTDCD was monitored in comparing with the DMG-GC-DOT transistor, the effect of variations of technology parameters, was presented in terms of gate polarization and drain polarization. The results indicate that the DMG-GC-DOTTDCD devices have characteristics higher than the DMG-GC-DOT MOSFET. To validate the proposed model, we used the results obtained from the simulation of the device with the SILVACO-ATLAS-TCAD software
Design and development of combat robot for military applications
Get PDFIn this paper we have developed a combat robot which will assist our commandos to fight against terrorism. With additional weaponry system it can perform other tasks also. Our preliminary aim in this project is to design a combat robot which can be used to handle the unmanned situations like terror attack inside the building where the firing is heavy and the entry of commandos may be difficult. In such situations the combat robot with spy camera, which is controlled through the control room can be sent into the terrorist occupied area. The robot constantly sends the visuals captured through spy camera to the control room. Based on the visuals received from the robot the control room operator can give directions to the robot. This kind of spy robot can also be used in star hotels, shopping malls, jewelry show rooms
Live tracking of saline for betterment of patient
Get PDFIn hospitals, Saline is fed to patients to treat dehydration and use of saline improves their health. In current health care measures, whenever a saline is fed to any patient, the patient must be continuously monitored by nurse, doctor or caretaker. So basically, in all the hospitals nurse or caretaker is responsible for monitoring of saline. Due to the avoidance of nurses towards the saline level monitoring or lack of knowledge it can harm to the patients health. Therefore, to stop the patient from obtaining injured and shield their lives throughout saline feeding amount, the saline level observance system are developed. The planned system is made Internet web of Things (IoT) platform. The planned system includes of devices which can act as tier sensor for observance the crucial level of the saline within the saline bottle. Whenever the amount of the saline reaches to the predefined crucial level, then the nurses, caretaker, doctors are alerted through the alarm associate in Nursing an alert message are sent through the utilization of web to the involved nurses and doctors that there's a requirement for replacement of the saline bottle. This planned system may be utilized efficiently in homes as well as hospitals
A system verilog approach for verification of memory controller
Get PDFMemory performance has become the major bottleneck to improve the overall performance of the computer system. By using memory controller, there is effective control of data between processor and memory.

Verification plays an important role in any design flow as it is done before silicon development. It is done at time of product development for quality checking and bug fixing in design
Efficient robust speech recognition with empirical mode decomposition using an FPGA chip with dual core
Get PDFThe purpose of this paper is to accelate the computing speed of Empirical Mode Decomposition (EMD) based on multi-core embedded systems for robust speech recognition. A reconfigurable chip, Field Programmable Gate Array (FPGA), is used for the implementation of the designed system. This paper applies EMD to discompose some noised speech signals into several Intrinsic Mode Functions (IMFs). These IMFs will be combined to recover the original speech by multiplying their corresponding weights which were trained by Genetic Algorithms (GA). After applying Empirical Mode Decomposition (EMD), we obtain a cleaner speech for recognition. Due to the complexity of the computation of the EMD, a dual-core architecture of embedded system on FPGA is proposed to accelerate the computing speed of EMD for robust speech recognition. This will enhance the efficiency of embedded speech recognition system

Efficient adaptation of the Karatsuba algorithm for implementing on FPGA very large scale multipliers for cryptographic algorithms
Get PDFHere, we present a modified version of the Karatsuba algorithm to facilitate the FPGA-based implementation of three signed multipliers: 32-bit × 32-bit, 128-bit x 128-bit, and 512-bit × 512-bit. We also implement the conventional 32-bit × 32-bit multiplier for comparative purposes. The Karatsuba algorithm is preferable for multiplications with very large operands such as 64-bit × 64-bit, 128-bit × 128-bit, 256-bit × 256-bit, 512-bit × 512-bit multipliers and up. Experimental results show that the Karatsuba multiplier uses less hardware in the FPGA compared to the conventional multiplier. The Xilinx xc7k325tfbg900 FPGA using the Genesis 2 development board is used to implement the proposed scheme.
