Wavelet Analytical Study of Sulphur Dioxide as an Air Pollutant
Most of the sulphur dioxide in the atmosphere is anthropogenic by-product. It is one of the basic causes of acid rain worldwide. NAAQS set the level of sulphur dioxide in the atmosphere for the safety of human health and environment. Breathing of Sulphur dioxide becomes cause of many diseases concerned with respiratory system like Bronchitis, Asthma, etc. In the perspective of human health and environment protection continuous monitoring and analysis has become of great importance. Wavelet is a tool to analyze non-stationary signal and hence wavelet transforms provide excellent analysis of non-stationary time series of SO2 and extracts important information. Daubechies4 wavelet is orthogonal and compactly supportive and therefore, it is useful for multiresolution analysis of SO2 data. Wavelet transforms provide simple and accurate frame work for modelling the statistical behaviour of SO2 variation in the interest of public health and environment protection.

Convex optimization based Adaptive PID Controller in CSTR Plant with Deadline Constraint
Process control by error feedback is an effective method but it will not give proper feedback when plant show nonlinear data, so use optimization techniques which optimize in an effective manner but optimization algorithm takes more time converge so select effective algorithm, which shows effective time complexity for convergence. We propose Human dynamic optimization which shows significance difference.

Review on PID Controller with Intelligent System
This paper exhibited a survey investigation of tuning of Proportional Integral Derivative (PID) Controller for speed control of CSTR PLANT utilizing delicate processing strategies. CSTR PLANT engine is generally utilized as a part of businesses regardless of the possibility that its support cost is higher than the enlistment engine. Speed control of CSTR PLANT is pulled in extensive research and a few techniques are advanced. The PID controller is the generally utilized remunerating controller which is utilized as a part of nonlinear frameworks. This controller is broadly utilized as a part of a wide range of zones like aerospace, process control, manufacturing, automation and so forth. The tuning of PID parameter is extremely troublesome. There are different delicate processing systems which are utilized for tuning of PID controller to control the speed control of CSTR PLANT. Tuning of PID parameters is essential on the grounds that these parameters greatly affect the dependability and execution of the control framework

Recovery of RF Signal from Modulated Optical Signal
In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. This was overcome by using RF to optical domain converter. But that signal has to be recovered by converting the optical signal back to RF signal. This can be done by this system i.e. Optical to RF converter which is having photo detector, TIA and LNA. Here the modulated optical signal is detected by using photo detector, which detect the light signal and convert it to current signal. This current signal is converted to voltage signal and then required amplification is provided by using a LNA. Hence this system is a compact, and efficient system which is to provide a high speed optical to RF conversion.

Conversion of RF Signal to Optical Signal Using MZM
In previous proposed system, Radio frequency signal was transmitted through RF system. But the system had some disadvantages like non coherence and system was not efficient. Hence to overcome these drawbacks, RF over Fiber system is proposed. In the proposed system, RF signal is the message signal which is used to modulate the optical signal that has to be transmitted over the optical cable. Mach–Zhender Modulators (MZMs) are used to convert the RF signal to optical signal when the light cannot directly modulate for higher speed, the Lithium Niobate, Mach-Zhender Modulator (LN-MZM) is used, Continuous Wave Laser diode is used as the source and PIN diode is used as optical detector. To transmit the optical signal Polarization-Maintaining optical fiber (PMF or PM fiber) is used, this transmitted signal is detected at receiver by optical detector .Hence in RF over fiber system are small in size, these are flexible and is a very low loss technology using intensity modulation to transmit RF signal.

Speech Recognition in Noisy Environment-an Implementation on MATLAB
Speech is one of the ways to express ourselves naturally. So, speech can be used as a means to communicate with machines. In this work, using MATLAB as a platform isolated word recognizer is achieved. Speech signals get distorted by many kinds of noises. Hence, it is necessary to reduce the noise contained in the speech signal. This is called speech enhancement. Speech enhancement aims at improving the intelligibility of the speech. Noise has been removed using Spectral Subtraction with Over Subtraction technique. The feature extraction is carried out using MFCC and feature matching is achieved using HMM.
