THz Continuous Wave (CW) spectroscopy, both in transmission and reflection mode, is used for determining the attenuation coefficient and refractive index of Carbon Fiber Reinforced Polymer (CFRP) composites. Using CW transmission mode, attenuation coefficient of the CFRP sample has been calculated while the reflection mode setup has been used to calculate the refractive index of the sample. From the...
Many fluorescence spectroscopic studies have proven its novelty and considered as a promising tool in the diagnosis of any health disorders using biofluids. This technique is highly sensitive, real time, non invasive and also it holds many interdependent methods. Urine is one of the most diagnostically important biofluid as it carries specific proteins released from blood used in the collection of...
From the past decades it is observed that Stochastic Petri Net (SPN) is a better tool for design and analysis of biological systems. The factor of Randomness and Unclearness in the design of biological system paved the way for the use of SPN. A Generic human immunity system modeled as a SIR(Susceptible Infected and Recovered) model is considered and modeled using SPN and Continuous Petri Net(CPN)...
The purpose for this paper is to describe the central Embedded Controller development done for Mass Flow Controllers (MFCs) M100B system. Work caters to control M100B MFCs being used for one of the systems at National Chemical Laboratory. M100B MFC accurately measures and controls the mass flow rates of gases. The central controller for this system is non functional and technology is outdated and...
This paper explains the design of low cost multi-channel Data Acquisition (DAQ) hardware based on serial communication. The paper puts forward an overall scheme of the system involving the hardware and software design. The hardware design is based on microcontroller (AT89C51) and uses key ADC chip (ADC0808) to realize the acquisition of multichannel analog signals and software design is the implementation...
Cardiac ailments like Ventricular Tachycardia (VT) and Ventricular Fibrillation (VF) are life threatening conditions which require prompt medical treatment. Automatic External Defibrillator (AED) is a device that delivers shock when it encounters VF and rapid VT signals. In this paper we have attempted to develop an algorithm for AED that detects normal sinus rhythm, Ventricular fibrillation and ventricular...
The present manuscript describes the area under curve (AUC) method for the estimation of oil (fatty acid) in cotton seed non-destructively. The theory for AUC method is the area at selected analytical wavelength ranges over the sample spectra is directly proportional to the concentration of the components of interest. The oil content in cotton seed samples were analyzed using Near Infrared reflectance...
The main of this project is to control the TITO system (Quadruple tank process). For better control to achieve modeling of quadruple tank is required. The modeling is obtained by linearization technique and Jacobian matrix. The designing of controller is a challenging task. The system response is achieved using Decentralized PI (Proportional Integral) controller. The system response for two control...
A targeted approach to soot blow operation based on boiler operating conditions involves estimation of cleanliness factor. The present work introduces a way of estimating the cleanliness factor of thermal power plant reheater by artificial neural network (ANN). Three different algorithms used to train NN and their performance is compared. Based on the simulation studies it was observed that although...
In many process industries storage tanks are used to restore liquids requiring level control. Liquid height in each tank shows integrating plus dead time (IPDT) behavior. When two such tanks are connected in series gives us a double integrating plus dead time (DIPDT) process. A DIPDT process itself is unstable for step inputs/changes. Hence it is recommended to use a controller for stabilizing the...
In this paper, an attempt is made to find the control law using Row by Row Decoupling Problem (RRDP) and Triangular decoupling problem (TDP) concepts. Before finding the control law, the issues on specification and methodologies are addressed in detail. Finally, the control law is presented for two input and two output system for both cases. Simulation for each category is presented in detail.

An attempt is made to design the centralized controller based on the inverted decoupling structure (CCID) for non-square (nxm) processes with multiple time delays. To avoid the Moore-Penrose pseudo-inverse of the nominal plant with multiple time delays and Maclaurin series approximation, a centralized controller is decomposed into two components using inverted decoupling structure. The two components...
