Different types of multiplier are going to implement using XILINX ISE Design Suite 14.5 software and the performance will analysed with ordinary multiplier.
Instrument calibration is one of the primary processes used to maintain instrument accuracy. Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating or minimizing factors that would cause inaccurate measurements is a fundamental aspect of instrumentation design. Although the exact procedure may vary from product to product, the calibration process generally involves using the instrument to test samples of one or more known values called “calibrators.” The results are used to establish a relationship between the measurement technique used by the instrument and the known values. Computerized Maintenance Management Systems are increasingly being used to manage and control plant and equipment maintenance in modern manufacturing and service industries. Computerised systems are now being installed in preference to the manual (paper based) preventive maintenance systems that have been around for many years.

The project is to carefully allocate the timely harvested renewable energy of the sensor for Data Sensing and Data Transmission so that the sensors remains active during the whole process by dynamically adjusting its sensing rate and transmission based on the available energy. Rechargeable sensor network offers a wide range of applications in areas such as traffic monitoring, medical care, inhospitable terrain, robotic exploration, and agriculture surveillance. In RSN, thousands of physically embedded sensor sensors are distributed in possibly harsh terrain and in most applications, it is impossible to replenish energy via replacing batteries. So automatically recharge the batteries from solar devices. In order to cooperatively monitor physical or environmental conditions, the main task of sensor sensors is to collect and transmit data. It is well known that transmitting data consumes much more energy than collecting data. The advent of efficient recharge communications and advancement in electronics has enabled the development of low-power, low-cost, and multi functionality sensor sensors that are characterized by miniaturization and integration.

Traffic congestion and tidal flow management are two major problems in modern urban areas which leads to road accident and loss of life. Automatic Ambulance Rescue System (AARS) is introduced to avoid the loss of life. The main idea behind this scheme is ambulance can reach smoothly to hospital in time, by mechanically controlling traffic lights in path. The sensor senses the spot and the nearest ambulance reaches the accident spot. The traffic lights in the path of the ambulance are controlled. The ambulance is guided to hospital by server through shortest route. The vehicle unit installed in vehicle senses the accident and sends the location of the accident to the main server in the ambulance section. The main server finds the ambulance, nearest to the accident spot and also shortest path between ambulance, accident spot and nearest hospital.
Classification of objects in an image finds its application in many real-time systems such as video surveillance systems etc. The basic operation is to detect the object present in the image frame. The processes involved are i) Extracting the object features and ii) Feeding the features into a classifier. External factors such as illumination, brightness etc., have profound effect on the process of classification. These conditions can lead to misdetection of objects. Similarly, the selection of features for classification affects the classification efficiency. Hence optimized feature detection, efficient feature extraction and a supportive classifier selection is mandatory for accurate classification. An absolute combination of suitable optimization solution, feature for classification and a matching classifier is presented in this work.
Built In Self Test (BIST) is used to test the working functions of IC circuit and it is one of the merit in IC’s to check all the working functions inside the IC circuit. And one of the other cons of BIST is it does not need any other additional device or circuit to test the functions of IC as it has additional power and additional circuit than other devices. Thus BIST reduces the power consumption of addition circuit by consuming considerable power. There is no solution to overcome the problem of consumption of larger power even there are vast methods to reduce consumption of power. But one of the best existing power reduction method in BIST is PRPG, as it gives pseudo Random patterns to test. But it also produce considerable power consumption due to toggling and repetition of patterns. Therefore we can use RTPG to overcome the drawbacks of toggling and repetition in PRPG. RTPG is the Random Test Pattern Generator uses Multiple in Input Signature Register (MIST) in order to reduce the repetition. So the power consumption can be reduced by reducing the pattern in our proposed system.

A new transformer-less Buck–Boost converter with superb output voltage with fault tolerance capability is proposed in this undertaking. Compare with the traditional Buck–boost converter, the proposed buck–boost converter’s voltage advantage is squared instances of the former’s and its output voltage polarity is wonderful. These benefits enable it to work in a wider variety of nice output. The power switches of the proposed buck–boost converter operate synchronously. In the continuous conduction mode (CCM), two inductors are magnetized and capacitors are discharged during the transfer-on period, at the same time as two inductors are demagnetized and two capacitors are charged throughout the switch-off duration. The operating concepts, the steady-country analyses, and the small-sign version for the proposed buck–boost converter running in CCM are provided in element. The power electronics simulator (PSIM) and the circuit experiments are supplied to validate the effectiveness of the proposed buck–boost converter. Deriving a family of dual-switch of step-down dc/dc converters with fault-tolerant capability. The constraint sets within the derivation process make certain that minimum extra element is used to attain fault-tolerant operation. The operation of converters derived is flexible. Under regular operating situations, one in all the two switches can function a primary transfer to manipulate the electricity drift and the opposite switch is in stand-by mode. When a fault takes place on the main switch, the others which may be activated to provide an change present day direction to continue converter operation and hold output law. The fault-tolerant converters are derived with the aid of integrating a buck converter with a buck–boost converter.
Dual-buck inverters feature some attractive merits, such as no reverse recovery issues of the body diodes and free of shoot-through. However, since the filter inductors of dual-buck inverters operate at each half cycle of the utility grid alternately, the inductor capacity of dual-buck inverters is twice as much as H-bridge inverters. Thus, the power density of dual-buck converters needs to be improved, as well as the conversion efficiency.
The detailed derivation process of two five-level full-bridge topology modeling is presented. The operation modes, modulation methods and control strategies of the series-switch five-level DBFBI topology are analyzed in detail. The THIPWM technique operates by adding a third harmonic component to the sinusoidal modulating wave. It is possible to increase the fundamental by about 15.5% and hence, allow a better utilization of the DC power supply.
The power device losses of the three-level DBFBI topology and five-level DBFBI topologies, with different switching frequencies are calculated and compared. Both the relationship between the neutral point potential self-balancing and the modulation index of inverters are revealed. Simulation results have shown that the five-level series DBFBI topology exhibit higher efficiency than the five-level H-bridge inverter topology and the three-level DBFBI topology.
An investigation into the design of a standalone photovoltaic water pumping system for supplying rural areas is presented. It includes a study of system components and their modelling. The PV water pumping system comprises a solar cell array, DC DC buck chopper and permanent magnet DC motor driving a centrifugal pump. Thesis focuses on increasing energy extraction by improving maximum power point tracking (MPPT). P&O MPPT algorithm is investigated which uses to automatically adjust stepsize to better track maximum power point. These use PV source output power and the speed of the DC pump motor as input variables. Both generate pulse width modulation (PWM) control signals to continually adjust the buck converter to maximize power from the PV array, and thus motor speed and the water discharge rate of a centrifugal pump. System elements are individually modelled in MATLAB/SIMULINK and then connected to assess performance under different PV irradiation levels. First, the MP&O MPPT technique is compared with the conventional direct method .The results show that the MP&O MPPT has faster dynamic response and eliminates oscillations around the MPPT under steady state conditions. The MPPT methods are implemented in the simulated PV water pumping system and compared. The results confirm that the new methods have improved energy extraction and dynamic tracking compared with simpler methods.
