Development of driving cycle under real world traffic conditions: A case study

The modeling of a car is essentially done by taking into consideration the driving terrain, traffic conditions, driver’s behavior and various other factors which may directly or indirectly affect the vehicle’s performance. A vehicle is modeled for given specifications and constraints like maximum speed, maximum acceleration, and braking time, appropriate suspension for the gradient of the road and fuel consumption. Henceforth, a profound study and analysis of different drive cycles are essential. A time dependent drive cycle is a condensed form of data that helps us to determine the time taken to conduct the driving test on the road. This article highlights the development of a real driving cycle in the area of Tamilnadu, India. On-road vehicle’s speeds versus time data were obtained along the selected route. The data obtained were analyzed first and then a new driving cycle was developed

A Mathematical model for the effect of Gastrin in humans using Fuzzy Rayleigh distribution

Gastrin is a potent stimulant of lower esophageal sphincter pressure in human. Several observations suggest that lower esophageal sphincter pressure is under the control of gastrin concentration. Injections of gastrin produce a marked increase in lower esophageal sphincter pressure. Various doses of synthetic gastrin-I significantly increased lower esophageal sphincter pressure. In this paper, we developed a mathematical model using the fuzzy Rayleigh distribution for the effects of gastrin on lower esophageal sphincter pressure in humans. Key Words: Cumulative damage model, Rayleigh distribution, Gastrin

A significant energy management control strategy for a hybrid source EV

The conceptualization of Electric vehicles has been significant in solving the pollution due to the transportation problem. However, its design and working has not yet been perfected and can be optimized. An effective model of the electric vehicle is the integration of batteries and supercapacitors. In this paper, the optimal sharing of energy between the battery and the supercapacitor is provided by the Particle Swarm Optimization (PSO). The results reveal that the proposed algorithm can better share the energy between the hybrid sources. The simulations are carried out in MATLAB Simulink platform and the results obtained for ECE-15 driving cycle is presented

Adsorption of Mercury (II) Ions from Aqueous Solution by Activated Carbon Prepared from Morinda Citrifolia

Mercury is one of the toxic contaminant in the environment and a major concerm in world wide.In this paper the use of morinda citrifolia bark as adsorbent for the removal of Hg(II) ions from aqueous solution in the batch system was studied . Acid treated activated carbon (AMC) was investigated for the removal of Hg(II) from aqueous solution as batch experiments by varying initial concentration, adsorbent dosage, pH, equilibrium time and temperature. A maximum removal of 92% was achieved with an initial Hg (II) concentration of 2 mg/L, pH -5 and adsorbent dose of 0.8 g/ L. The obtained experimental data were fitted to Langmuir and Freundlich equilibrium isotherm models. Both the models were found to provide a better fitting with coefficient of regression

Performance analysis of PV powered multilevel inverter

This article deals with the PV based DC/DC boost chopper integrated nine level inverter. This topology requires 7 switches in minimum to obtain a nine level stepped wave output. So the main objective of this paper is to develop a 9 level AC output using PV based DC/DC boost chopper. In the case of conventional multi-level inverter, 16 switches were utilized and the number of sources needed was also more. Here the proposed system comprises of single PV panel and the switches used are also less. Also PV is integrated with DC/DC boost chopper is used to increase the source input level of the inverter. Using MATLAB platform, the proposed system is simulated with a resistive and inductive load. The similar results are obtained in prototype which validates the designed converter

On the recent Introduction of outboard engines along the Coromandal coast

Introduction of outboard engines along the Coromandal coast and Pondicherry were studied. A total number of 232 outboard engines have been introduced at 16 fish landing centres in the South Arcot District. The outboard engines are fitted exclusively to catamarans with a length range of 8-10 m operating mainly gill nets, Pannu valai and Mani valai and the encircling bag-net, Eda valai
