The main aim of this paper is fault testing of analog integrated circuits by simultaneous analysis of the gain vs frequency and phase vs frequency between faulty and fault free circuits. For the analysis, differential amplifier and single stage amplifier have been used as no work has been done for fault detection and localization of circuits containing BJTs analog ITC'97 benchmark circuits. The value...
Recently, there has been increasing interest in low-cost, non-contact and pervasive methods for monitoring physiological information for the drivers. For the intelligent driver monitoring system there has been so many approaches like facial expression based method, driving behavior based method and physiological parameters based method. Physiological parameters such as, heart rate (HR), heart rate...
A novel integrated fault diagnosis method of 8 bit Digital to Analog Converter (DAC) circuit is presented in our paper. The circuit is based on the one presented in the IEEE 1997 International Test Conference (ITC'97). The gain waveforms of faulty and faults free (Golden) circuits as well as internal node voltages of two stage CMOS Operational Amplifier is used to detect the faults. An assembled fault...
The basis of this project is to create an electronic voting machine that will help to eradicate defrauding of the manual voting systems by multiple votes cast by the same user. With the inclusion of a Near Field Communication ID card reader and biometric fingerprint device, each voter will be entered into the system through a swift process only after being recognized and checked to the given database...
Under this present study, thermal and mechanical behaviors dependence of insulating fire bricks (produced by burnout process) on coal percentage (mass %) were investigated. Waste coal powders or coal dust were collected from mines, transport vehicles, storage areas etc. Specimen insulating bricks were produced by uniaxial pressing in a steel mould. The main materials were fireclay consisting of silica...
Disturbances to an interconnected power system lead to fluctuation of electrical quantities such as voltage, current and frequency. Generally abnormalities lead to fall of system frequency and the initial reaction of the power system to a disturbance is called inertial response of the system which is a function of system inertia constant (H), the higher the system inertia constant the slower the rate...
Formation of island may be inadvertent which is due to system fault or intentional for a purpose of system maintenance. Generally fall of frequency is lead by abnormal condition to a power system and sometimes blackout of an integrated system is occurred due to extreme abnormality. Though traditionally, interconnection standards avoid islanding operation but in case of emergency islands can support...
Operation of a large power system with maintaining proper power quality is always been a difficult task. It becomes more difficult to maintain the power quality when rapid expansion of previously designed power system occurred. To redesign of such a power system is not feasible and also cost effective. To improve the quality of power of such a large system, conventional methods of compensation can...
