The study of rotation curve with MOND for ESO138-G014
No full textThis paper is devoted to solve the galactic rotation problem based on Modified Newtonian Dynamics (MOND). It addresses a new fundamental constant a0, called the acceleration constant, at which acceleration scale of Newton's second law fails to hold. It is an indication of a breakdown of classical Newtonian dynamics. In this respect, we choose the HI observations of a late type galaxy, ESO138-G014, to test the rotation curve within the MOND framework which leads to "MOND RC". We ask whether ESO138-G014 is compatible with MOND or dark matter is still favorable for the galactic rotation problem. © 2013 AIP Publishing LLC

Modelling enzyme electrodes – what do we learn and how is it useful?
No full textThere has been an enormous increase in the computational power readily available since the first numerical treatments of electrochemical problems in the early 1960s. This development has been accompanied by the development of powerful, widely available, commercial software modelling tools. Despite this, approximate analytical treatments remain extremely useful in the modelling of coupled diffusion/reaction problems in electrochemistry because of the insights they provide into the different possible behaviours of the system. In this paper we discuss the modelling of amperometric enzyme electrodes, taking as our exemplar redox hydrogel-based enzyme electrodes in which the enzyme is immobilized in a redox active polymer which wires the enzyme to the electrode. In this system the measured current is related to many different experimental variables including substrate concentration and diffusion coefficient, reaction rate constants, and film properties and thickness. The interplay of these factors is described and the role of Case diagrams in understanding coupled diffusion/reaction problems of this type is discussed.</p
Optimization of amperometric biosensor design using mathematical modelling and simulation
No full text425 million adults suffered from diabetes globally in 2017 with a predicted increase of 50 % by 2045. One good way to reduce the impact of this disease is by continuously monitoring the glucose levels of the patient using analytical devices. We are trying to research a specific case of such analytical devices i.e., enzyme immobilized redox polymer layered biosensors for continuous glucose monitoring using mathematical models. We have applied a transient numerical scheme using the commercial software MATLAB to solve the mathematical model. Mathematical verification of the system has been carried out by comparing our numerical results to steady state analytical solutions. We are trying to understand the transient regimes before the system reaches steady state. A novel validation procedure has been devised using the deflavinated enzyme to change the kinetic parameters in the physical system. The response will be compared with the simulated results.We also present an optimization of the physical system by using engineering constraints. This work has the potential to better explain the working of analytical devices and improve their working. <br/
Modeling and calibrating capacity of large roundabouts
No full textRoundabout models, available in the literature widely, vary between one method and another. Majority of the
models are solely based on circulating fl ow to estimate capacity. The relationship between maximum entry
fl ow of large dual and triple lane roundabouts and their geometric and traffi c characteristics is investigated
here for saturated fl ow condition using multivariate analysis. The developed model, based on the data gathered
from 13 roundabouts in Bahrain, matched the fi eld data reasonably well. The signifi cant predictors, out of
60 tested ones, included circulating and exiting fl ows, number of entry and circulating lanes, circulating and
entry widths, inscribed diameter and fl are length. Capacities predicted through various international models
varied considerably with both the developed model and the fi eld data. The international models were then
calibrated against the model, and consequently the fi eld data, so as to have signifi cant match with the two. The
procedure followed in developing the model and calibrating the international models consisted of eight stages.
It involved identifi cation of signifi cant correlation of individual predictor with capacity, multivariate regression
analysis, model smoothing, multi-collinearity test, redevelopment of the model after adjusting the variables
causing collinearity, comparison analysis with seven known international models and calibration of the international
model. While UK, aaSIDRA and French models required around 50% reduction to match the developed
model and actual data; US FHWA and Swiss models required 25% reduction and US HCM and German models
required just 8% adjustments. Such clear variations call for further research. The fi ndings assist the urban planners
as when to shift from one type of intersection control into another involving roundabout, and vice versa
