Damage identification in beams based on the observation of frequencies and modal curvatures
No full textThis work investigates numerically and experimentally the dynamic response of a free-free beam in its undamaged and damaged states, in terms of natural frequencies and modal curvatures. The damage consists of a height reduction extending to all the base of the cross section, and is described by three parameters, that are: depth of the height reduction, extension, location of its axis of symmetry along the beam axis. The resulting direct problem is solved via a 2D plane-stress finite element analysis, covering a dense grid of the three damage parameters. Several experimental tests are conducted on steel beams, covering selected values of damage parameters, and using strain gauges with grids of different lengths to understand how this sensor characteristic affects the measurement of the strain. The natural frequencies and modal curvatures obtained from the solution of this direct eigenvalue problem are compared to their experimental counterpart to evaluate the capability of the model to describe real data. Furthermore, the solution of the inverse problem of damage identification is carried out, providing some insight into the identifiability of the three damage parameters. The solution of the inverse problem is approached minimizing objective functions that measure the differences between numerical and pseudo-experimental and experimental variations of natural frequencies and/or of modal curvatures in the undamaged and damaged states
Symmetries, solutions and conservation laws of a class of nonlinear dispersive wave equations
No full textIn this paper we consider a damped externally excited Korteweg-de Vries (KdV) equation with a forcing term. We derive the classical Lie symmetries admitted by the equation. We then find that the damped externally excited KdV equation has some exact solutions which are periodic waves and solitary waves. These solutions are derived from the solutions of a simple nonlinear ordinary differential equation. By using a general theorem on conservation laws and the multiplier method, we construct some conservation laws for some of these partial differential equations
Nonlinearly Self-Adjoint, Conservation Laws and Solutions for a Forced BBM Equation
No full textWe study a forced Benjamin-Bona-Mahony (BBM) equation. We prove that the equation is not weak self-adjoint; however, it is nonlinearly self-adjoint. By using a general theorem on conservation laws due to Nail Ibragimov and the symmetry generators, we find conservation laws for these partial differential equations without classical Lagrangians. We also present some exact solutions for a special case of the equation
Four kilobyte memory array for Magnetic Random Access Memory development
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 129-131).The circuits for a A 4kb array of Magnetic Tunnel Junctions (MTJs) have been designed and fabricated in a 0:18¹m CMOS process with three levels of metal. Support circuitry for addressing, reading, writing, and test mode probing enables the characterization of the switching of a thin-film ferromagnetic layer in the MTJs. Specifically, novel mechanisms involving spin-transfer or thermal assistance can be studied and compared to current MRAM designs that switch the MTJ with current-induced magnetic fields. Using this array design, both high speed digital and quasi-static dI/dV experiments can be conducted to investigate the nature of the MTJ resistance hysteresis and process variation in addition to the switching behavior under both polarities of current.by Masood Qazi.M.Eng
مختار مسعود کی تحریروں میں فلیش بیک کی تکنیک
No full textVarious stylistic techniques are used by the writers to illuminate their text as well as to convey the essence of their works to the readers. "Flash back" is one of these techniques. The famous urdu writer Mukhtar Masood has also used this very technique in a successful manner. In this article, the author has ciritically analysed the used of the said technique in the works of Mukhtar Masood
A Design Tool for Passive Wrist Support
No full textA design tool for passive wrist support using compliant spatial beams as gravity balancer is presented. The aim of this assistive device is to reduce required effort for pronation-supination and flexion-extension by 70% to help patients with muscular weakness keeping their hand’s posture and doing daily tasks, while the forearm is rested. To reach this goal, a setup with three connection points to the user’s hand, and two optimized spatial beams as elastic gravity compensators, are developed. The overall shape and cross-sectional dimensions of the compliant beams are attained using an optimization technique. The objective is reaching a desired endpoint kinetostatic behaviour which is determined based on the hand’s weight and available muscular forces. A design case is presented to show the ability of the method, and the final errors from the desired behaviour are clarified. In the end, possible further applications of the design tool are discussed.Accepted Author ManuscriptMechatronic Systems DesignPrecision and Microsystems Engineerin
Explosive indentation study of B4C-TiAlx composites fabricated by the dipping exothermic reaction process
No full textThe aim of this study is to fabricate a high volume fraction B4C-reinforced intermetallic matrix composite by the dipping exothermic reaction process and investigate the shock impact damage response of composites by explosive indentation experiment. It has been shown that the final microstructure of the dipping exothermic reaction process-fabricated composite can be tailored by treatment of the constituent powders and post heat treatment. The hardness and impact damage resistance of the fabricated composites were evaluated.This work is supported by grants (No. N62649-03-0007) from AROFE(US Army

Estimating the Black Economy through Monetary Approach: A Case Study of Pakistan
No full textIn the recent years, the ‘black economy’ has held enormous appeal for policy makers. Presence of black economy creates critical misrepresentation of macroeconomic variables in official estimates that lead to the false determination and delusional impact of economic policies. Similarly, black economy represents the unrecorded potential of the economy vis-à-vis resource generation and mobilization. The Economy of Pakistan underwent several minor tax reforms since 1960’s. However, the tax and tariff reform of 1990’s, committed under international pressure, was the first comprehensive exercise and therefore it becomes highly desirable to gauge its impact on the black economy and tax evasion practices. This paper, with some modifications, uses the standard monetary approach to obtain the latest estimates of the size of black economy and its macroeconomic implications thereof.
