Reactive Molecular Dynamics Simulations to Understand Mechanical Response of Thaumasite under Temperature and Strain Rate Effects

Understanding the structural, thermal, and mechanical properties of thaumasite is of great interest to the cement industry, mainly because it is the phase responsible for the aging and deterioration of civil infrastructures made of cementitious materials attacked by external sources of sulfate. Despite the importance, effects of temperature and strain rate on the mechanical response of thaumasite had remained unexplored prior to the current study, in which the mechanical properties of thaumasite are fully characterized using the reactive molecular dynamics (RMD) method. With employing a first-principles based reactive force field, the RMD simulations enable the description of bond dissociation and formation under realistic conditions. From the stress–strain curves of thaumasite generated in the x, y, and z directions, the tensile strength, Young’s modulus, and fracture strain are determined for the three orthogonal directions. During the course of each simulation, the chemical bonds undergoing tensile deformations are monitored to reveal the bonds responsible for the mechanical strength of thaumasite. The temperature increase is found to accelerate the bond breaking rate and consequently the degradation of mechanical properties of thaumasite, while the strain rate only leads to a slight enhancement of them for the ranges considered in this study

RESEARCH AND REVIEWS: JOURNAL OF ENGINEERING AND TECHNOLOGY Registered Images Single Composite Entity Classified Algorithm into Linear Superposition Pyramid Decomposition

ABSTRACT For keeping the signal exponents at the singular points of the underlying signal and lifting its smoothness at all the remaining points. An extension of the non-linear smoothness constrained filter to image processing is studied at this paper. Numerical experiments demonstrated that our approach is effective and efficient. there exists a polynomial of degree such that is a piecewise smooth signal, infinitely differentiable and there exists a polynomial of degree the definition of H¨older exponent, conclude that admits for all except the singular points. Then we can rewrite the above equation by theorem. it admits as its exponent

Research and Reviews: Journal of Engineering and Technology Transformed Chaotic Signals with Lyapunov Spectrum for Quantitative Measure of Its Sensitivity to Initial Conditions

ABSTRACT The purpose of this paper is to consider a class of recursively defined signals that exhibit complex dynamics in phase space. This work arose out of an interesting radar signal. This signal exhibits sensitive dependence on initial conditions, and has an unusual self replicating feature in phase space. The main issue to be addressed in this paper is whether such signals are of practical use in radar. Signals are of paramount importance in radar. Radar systems use different types of signals for specific applications in varying situational contexts

Features classification based on redundancy segmentation in observing minute details group

ABSTRACT Context helps a learner to learn about the world. Context can start as a shallow understanding of a situation, place, scene or conversation. This shallow understanding allows a learner to draw connections to previously acquired knowledge, and to specialize a context if necessary. Learning must take advantage of redundancy, and context allows redundancy to be identified. Context can help one make a quick judgment of novelty. In a new situation, the learner should tread more carefully, observing minute details in order to make sense of the complex whole. When exposed to a similar situation, however, the learner can build upon the work done during the previous encounter

HIERARCHICAL INDEXING FOR FASTER RETRIEVAL BASED ON FULL AUTOMATIC ALGORITHM

In this paper, we aim to take advantage of texture properties of images to improve the performance of the image indexing and retrieval algorithm. Beside that a framework for segmentation of the image which results in categorizing and identifying the object in image is presented. Image retrieval based on region is one of the most promising and active research directions in recent years. In this study, the combination of the texture features and regioing method provide an efficient feature set for image retrieval. Experimental results exhibit that the proposed method yield higher retrieval accuracy than some conventional methods even though its feature vector length and feature generating time of query image is less than those of other approaches.

Design and Implementation of Low Profile Antenna for Dual-Band Applications Using Rotated E-Shaped Conductor-Backed Plane

A novel configuration of a printed monopole antenna with a very compact size for satisfying WLAN operations at the 5.2/5.8 GHz and also for X-band operations at the 10 GHz has been proposed. The antenna includes a simple square-shaped patch as the radiator, the rotated U-shaped conductor back plane element with embedded strip on it, and the partial rectangular ground surface. By using the rotated U-shaped conductor-backed plane with proper values, good impedance matching and improvement in bandwidth can be achieved, at the lower and upper bands. The impedance bandwidth for S11<-10 dB is about 1.15 GHz for 5 GHz band and 5.3 GHz for X-band. The measured peak gains are about 1.9 dBi at WLAN-band and 4.2 dBi at X-band. The experimental results represent that the realized antenna with good omnidirectional radiation characteristics, enough impedance bandwidth, and reasonable gains can be appropriate for various applications of the future developed technologies and handheld devices
