Data validation and reconciliation (DVR) plays key role in industries because it uses process information and statistical methods to estimate correct measurements from the observed data. DR is very effective when measurement is free from gross error. Data observed from chemical processes can be serially correlated. Serial correlation in data can arise when a process, takes time to adjust, is exposed...
Pulse oximeters are ubiquitous in modern medicine to noninvasively measure the percentage of oxygenated hemoglobin in a patient's blood. Pulse oximeters are well adapted, simpler and quite easy to measure. In this paper, An ANN based model using LabVIEW is proposed to measure and estimate the SpO2 present in the blood. Infra red (IR) and red LED lights are passed through the fingers and the ratio...
Most of the power plants are automated with complete closed loop control systems. For this purpose, numerous sensors are required to monitor the proper functioning of the plant. Due to various reasons, these sensors may not be able record actual value of the measured variable. This misleads the controller taking faulty actions on manipulated variables. It is very important to monitor the measured...
In today's computer world security is the major issue. For every project most of the money spent on the security and testing than developing. Because security issue is one of the major issue for everyone to protect data. According to the security analysts more than seven billion hackers are existing over one hundred and five billion computers. Almost all of them trying to collapse the security system...
Due to raising concerns about the privacy preserving of personal information, organizations which are using the customers' records in data mining activities are rammed to take actions for protecting the individual's privacy. Preserving of sensitive and personal information is vital for the success of data mining techniques. Privacy Preserving Data Mining (PPDM) handles such consequences by reconciliation...
In this paper, we consider a wireless communication with a single source node, single destination node and L number of amplify and forward (AF) relay nodes. With rayleigh channel, the communication between source node and destination node is established through relay nodes. The channel coefficient and their estimate are related by two error models namely, stochastic error model and channel time variation...
Effective Control of Complex process in power generation industries is a challenge to instrumentation engineers. Most importantly coordination of sensor functioning should be monitored regularly. So, a sensor validation and data reconciliation methods are adopted for monitoring the data and faulty data are replaced. In this paper neural network based data validation method is developed and tested...
DC-DC converters can be viewed as dc transformers that deliver a DC-DC voltage or current at a different level than the input source. The unregulated DC voltage is converted into regulated DC voltage at required level under varying load and input voltage condition. The control of output voltage is performed in a closed loop using the principle of negative feedback.The fuzzy logic controller for DC-DC...
Sensor data validation is essential for the successful operation of any complex dynamic system, which is largely dependent on the validity of the sensor data. As the sensor data is used for the display and control purposes, the overall process output would be faulty if the sensor data is erroneous. In this paper a Takagi-Sugeno Fuzzy Inference System is used to determine the data-confidence of the...
There are many algorithms to improve the channel estimation of MIMO-OFDM system based on blind, semi blind and training methods. But still, it can be improved. Signal perturbation free transmit scheme is one of such schemes to improve it. This scheme transmits the data which bears the partial information of the correlation matrix of the transmitted signal to the receiver in order to cancel the signal...
Robots require compact, power efficient and regulated power supplies for their efficient operation. This paper deals with the problem of developing such a power supply. A single-output zero voltage switching pushpull converter with low switching and conduction losses for robotic applications has been presented in this paper. The proposed converter is designed for outputs of 5 V/ 1 A with a switching...
Porous salmon calcitonin (sCT)-loaded PLGA microspheres (size range 35-140 μm) of varying matrix characteristics were prepared by an aqueous emulsification process using either a temperature gradient (Tmp) or dilution (Dil) of the continuous phase (CP). The Tmp technique resulted in microspheres with a hollow internal core and a porous wall. The core size and thickness of the porous wall were dependent...
