Increased medical expenditure, improper treatment, decreased productivity and above all inadequate pain, assessment is the global challenging problem, causing a substantial burden on the individual, their family, and society which often leads to loss of interest in life. The facial expression variation generally reflects clue for the occurrence of pain. This offers a vital aspect for non-verbal patients who are not in a position to rate their pain intensity level. The hypothesis proposes the developing of a multimodal machine based tool which will assess pain intensity. A framework has been designed to meet up with these specific issues which involve extracting features from the face and genes involved in pain. Patients suffering from pain require a comprehensive assessment to be conducted for proper diagnosis. The contributions of this paper are fourfold: Firstly, this paper provides an efficient approach to computational pain quantification. Secondly, it investigates the medical practitioner perception to pain along with the readings of the various tools available. Thirdly, the psychological aspect is taken into consideration to predict how pain is perceived by observers and experts (physicians). Fourthly, genes involved in pain and no pain conditions are taken and classified. Three large databases of spontaneous pain expressions are used i.e., McMaster UNBC Pain Archive database, self-prepared database and the other BioVid heat pain database of pain to verify the accuracy and robustness of the system. The methodology achieves 87% accuracy rate for classification of frames amid four levels of pain intensity. Designing intelligent computing systems with the given methodology will certainly improve the quality of life of patients. © 2017 Springer Science+Business Media New York

This paper presents the dynamic performance of Load Frequency Control (LFC) of four area hydrothermal interconnected power system by using Artificial Intelligent Controller (ANN and Fuzzy) and conventional (PI & PID) control approaches. Area-1 and area-2 consists of thermal reheat power plant whereas area-3 and area-4 consists of hydro power plant. To enhance the performance of Intelligent and Conventional controller sliding surface is included. The performances of the controllers are simulated using MATLAB/SIMULINK package. A comparison of Intelligent and Conventional controller based approaches shows the superiority of proposed ANN & fuzzy based approach over PI & PID for same conditions. © 2012 IEEE.

The present theoretical analysis is to investigate the effect of non-Newtonian Pseudoplastic & Dilatant lubricants (lubricant blended with viscosity index improver)-Rabinowitsch fluid model on the dynamic stiffness and damping characteristics of pivoted curved slider bearings. The modified Reynolds equation has been obtained for steady and damping states of the bearing. To analyze the steady state characteristics and dynamic characteristics, small perturbation theory has been adopted. The results for the steady state bearing performance characteristics (steady state film pressure, load carrying capacity and centre of pressure) as well as dynamic stiffness and damping characteristics have been calculated numerically for various values of viscosity index improver using Mathematical 7.0 and it is concluded that these characteristics vary significantly with the non-Newtonian behavior of the fluid consistent with the real nature of the problem. © 2012 Published by Faculty of Engineering.

The present theoretical analysis investigates the simultaneous effect of lubricant inertia and non-Newtonian pseudoplastic lubricant (lubricant blended with viscosity index improver and viscosity thickener)-Rabinowitsch fluid model on the performance of externally pressurized annular hydrostatic thrust bearings. A close form solution is obtained for pressure distribution. The effect of centrifugal inertia on the pressure distribution in the recess region is considered by taking non-constant recess pressure under a hydrodynamic condition. The load capacity and flow rate have been numerically calculated for various values of viscosity index improver together with the centrifugal inertia effects. In the limiting case in which there is an absence of pseudoplasticity, the results are compared with the pre-established Newtonian lubricants and are found to be in good agreement. © 2012 American Society of Mechanical Engineers.

The present theoretical analysis is to investigate the effect of non-Newtonian pseudoplastic lubricant (lubricant blended with viscosity index improver and viscosity thickener)-Rabinowitsch fluid model on the performance of externally pressurized hydrostatic thrust bearing. The expression for pressure has been derived using an energy integral approach. The load capacity and frictional torque of the bearing have also been numerically calculated for various values of viscosity index improver along with the centrifugal effects. The results so obtained are compared and found to be in good agreement with the earlier theoretical and practical results of Dowson, and the effect of viscosity index improver is also analyzed. © Society of Tribologists and Lubrication Engineers.

In the present theoretical investigation, the effect of ferrofluid on the dynamic characteristics of curved slider bearings is presented using Shliomis model which accounts for the rotation of magnetic particles, their magnetic moments, and the volume concentration in the fluid. The modified Reynolds equation for the dynamic state of the bearing is obtained. The results of dynamic stiffness and damping characteristics are presented. It is observed that the effect of rotation of magnetic particles improves the stiffness and damping capacities of the bearings. © 2012 Udaya P. Singh and R. S. Gupta.

In practice, lubricants' stability is improved by blending different additives (viscosity index improvers) such as polyisobutylene, ethylene-propylene, lithium hydroxy stearate and hydrophobic silica. Due to the additives, the lubricants exhibit non-Newtonian pseudoplastic and dilatant nature, which can be described by Rabinowitsch fluid model. In the present analysis, the squeezing characteristics between a long cylinder and a flat plate, lubricated with non-Newtonian pseudoplastic and dilatant lubricants, have been investigated. The modified Reynolds equation has been derived in the analysis and the close form solution for film pressure is obtained. The results for the pressure distribution, load-carrying capacity and time-height relationship under squeezing characteristics have been calculated numerically for various values of pseudoplastic parameter (i.e. different values of viscosity index improver). The effect of cavitation is also analyzed in the analysis. It is concluded that these characteristics show significant variation with the non-Newtonian pseudoplastic and dilatant behavior of the fluids. © IMechE 2012.

In the present theoretical analysis, the combined effects of slider curvature and non-Newtonian pseudoplastic and dilatant lubricants (lubricant blended with viscosity index improver) on the steady and dynamic characteristics of pivoted curved slider bearings have been investigated for Rabinowitsch fluid model. The modified Reynolds equations have been obtained for steady and damping states of bearing. To solve the modified Reynolds equations, perturbation theory has been adopted. The results for the steady state characteristics (steady state film pressure, load carrying capacity and centre of pressure) and dynamic characteristics (dynamic damping and dynamic stiffness) have been calculated numerically for various values of viscosity index improver using Mathematica. In comparison with the Newtonian lubricants, higher values of film pressure, load carrying capacity, dynamic damping and dynamic stiffness have been obtained for dilatant lubricants, while the case was reversed for pseudoplastic lubricants. Significant variations in the bearing characteristics have been observed for even small values of pseudoplastic parameter, that is, with the non-Newtonian dilatant and pseudoplastic behaviour of the fluid.
