Determination of Accurate Molecular Weights of Cationic Polyacrylamide Polymers through Advanced Gel Permeation Chromatography Triple Detection Technique
Abstract: AbstractGel permeation chromatography along with refractive index detector or UV detector provides relative molecular weight information along with PDI with respect to standard used. If standards are of different nature than sample such relative results just are used to compare polymers and co-polymers among themselves. These detectors fail to reveal information about other important polymer characters like size of polymer in solution (hydrodynamic volume), branching pattern and intrinsic viscosity which …

Determination of Quick Switching Double Sampling System by Attributes under Fuzzy Poisson Distribution: Acceptance Number Tightening
Abstract: AbstractAcceptance sampling plans are used to accept or reject the lots based on the inspection of samples. A mixture of acceptance sampling plans with switching rules for changing from one plan to another are called acceptance sampling schemes. The simple and most generally used sampling scheme is quick switching system (QSS-1). Quick switching system with reference to single sampling plan is a system which requires fewer samples for processes running …

Biochemical Analysis of Cadaveric Synovial Fluid for Determination of Death Interval
Abstract: Estimation of post-mortem interval or time since a death has always remained an important requirement in medico-legal autopsies. Since the 1850s, scientists have been working on different methods to determine post-mortem interval but none of the methods is either or collectively reliable in measuring exact death interval because of environmental factors. Hence in this study, synovial fluid sodium concentration was investigated to predict post-mortem interval. Total 100 samples of the …

Determination of Maximum Allowable Pump Speed for Transferring Fluid to a Vertical Height at Constant Power
Abstract: This work determines the maximum possible velocity fluids can be transported through a vertical height at constant pump power. The analysis involves simulation of theoretical piping equations and analysis of the pump pressure, frictional pressure drop and static (atmospheric) pressure with respect to flow velocity using MS excel and Matlab. Computational results obtained from MS excel and represented graphically in Matlab establish the maximum allowable velocity – below which the …

Investigation of Parameters Determining Thermosyphon Flow-Velocity in a Simulated Solar Water Heater
Abstract: Real life experimental investigations that involve natural variables are essential and necessary in determining the performance characteristics of systems that depend on them but they are not easily repeatable under the same conditions. The alternative approach is the modelling and simulation of such systems. This work however, is concerned with the experimental investigation of the performance characteristics of thermosyphon solar water heating system using an electrically simulated collector. Heating rate …

Attitude Determination using Extended Kalman Filter for Elliptical Orbit Satellites
Abstract: This paper investigates the influence of eccentricity on the performance of the attitude determination and control subsystem (ACDS) pointing of passive low earth orbit (LEO) satellites stabilized by a gravity-gradient boom. The contribution of this work is two-fold. First, satellite attitude dynamics and kinematics are modeled by introducing the orbit eccentricity in the equation of motion of an LEO satellite in order to provide the best scenarios in which satellite …
