invert sugar is the result of sucrose of hydrolysis of sucrose by acid or enzyme, that is, the splitting of sucrose molecules into their glucose and fructose components.invert sugar is used in different industries such as; food industry, soft drinks and pharmaceutical, due to its special characteristics such as; sweetness level, moisture ability’s property, crystallization level and special tas...

In the seismic inversion model, as the neural network algorithm there are some problems, the convergence bad, accuracy is not high. This paper presents a seismic inversion based on artificial fish Swarm Optimization neural network models. First to initialize fish mapping of chaos optimization and ergodicity of artificial fish-swarm search and adaptive strategies of artificial fish-swarm algorit...

Minimum-structure inversion has been widely used in both hydrocarbon and mineral exploration for decades. However, models obtained with this method typically exhibit smooth variation of physical properties and smeared-out boundaries, and may not give detailed information about the target being investigated. In this paper we present a constrained joint inversion of surface and borehole gravity t...

One of the most challenging problems in electromagnetic (EM) geophysical methods is developing fast and stable methods of EM modeling and inversion for 3-D inhomo­ geneous geoelectrical structures. In this paper I present an overview of the research conducted by the Consortium for Electromagnetic Modeling and Inversion (CEMI) at the University of Utah on developing fast forward mod­ eling and i...

The imitation of spoken stop consonants by an articulatory synthesizer using only general learning principles addresses significant issues in speech inversion and speech acquisition. Stop consonants are relatively large, complex acoustic events resulting from discrete articulations, so inversion based on the use of small time windows or based on the minimisation of average articulatory error ac...

one of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. therefore, in this work, it is attempted to develop an inversion approach to determine a 3d density distribution that produces a given gravity anomaly. the subsurface model consists of a 3d rectangular prisms of known sizes ...

The ability of a block inversion scheme, in which polygons are employed to define layers andror bodies of equal resistivity, in determining the geometry and true resistivity of subsurface structures has been investigated and a simple strategy for deriving the starting model is proposed. A comparison has also been made between block inversion and smooth inversion, the latter being a cell-based s...

[1] The Global Positioning System (GPS) system now makes it possible to monitor deformation of the Earth’s surface along plate boundaries with unprecedented accuracy. In theory, the spatiotemporal evolution of slip on the plate boundary at depth, associated with either seismic or aseismic slip, can be inferred from these measurements through some inversion procedure based on the theory of dislo...

In this paper we describe a new approach to shar p boundary geophy sical inversion. We demon strate that regularized inversion with a minimum support stabilizer can be implemented by using a specially designed nonl inear parametrization of the mode l parameters . Thi s parametrization plays the same role as transformation into the space of the weighted model parameters, introd uced in the origi...

The security of pairing-based cryptosystems is closely related to the difficulty of the pairing inversion problem. Building on previous works, we provide further contributions on the difficulty of pairing inversion. In particular, we revisit the approach of Kanayama-Okamoto who modified exponentiation inversion and Miller inversion by considering an “auxiliary” pairing. First, by generalizing a...
