Biodiesel production from tomato seed and its engine emission test and simulation using Artificial Neural Network
In this study, tomato seed oil was used to produce Biodiesel fuel. To reduce the percentage of free fatty acids, the oil was reacted at a temperature of 40, 50, and 60°C with a mixture of sulphuric acid and the industrial methanol with different molar ratios of oil. The best conversion efficiency was achieved at 60°C and a molar ratio of 1:9. In the transesterification step, biodiesel was produ...
متن کاملAcoustic Emission Source Location in Steel Structures Using a Wavelet Transform Analysis and Modal Location Theory
Source location is an important feature of acoustic emission (AE) damage monitoring in steel structures. The ability to accurately locate sources can assist in source characterisation and early warning of failure. This paper describe the development of a novel AE source location technique termed “ Wavelet Transform analysis and Modal Location (WTML)” based on Lamb wave theory and time-frequency...
متن کاملA generalized ABFT technique using a fault tolerant neural network
In this paper we first show that standard BP algorithm cannot yeild to a uniform information distribution over the neural network architecture. A measure of sensitivity is defined to evaluate fault tolerance of neural network and then we show that the sensitivity of a link is closely related to the amount of information passes through it. Based on this assumption, we prove that the distribu...
متن کاملscour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
A Lab-scale Digital Acoustic Emission System for Source Location
coustic emission (AE) techniques have been used * of arrival-time differences (delta-T’s) for each mesh point. To in the study of crack location, cracking mecha‘ calculate the source position for a set of burst-type AE signisms, deformation of metals and leak detection. : nals, a straightforward “shift and a d d method was used. A In these techniques, AE sensors hit by transient . First, assumi...
