Eccentricity and therm.viscous effects on ultrasonic scattering from.a liquid-coated fluid cylinder

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2008年第1期9卷 65-78页

作者： Seyyed m. HASHEm.NEJAD m. A. ALIBAKHSHI Acoustics Research Lab. Department of Mechanical Engineering Iran University of Science and Technology Narmak Tehran 16844 Iran

Calculation of the scattered field of the eccentric scatterers is an old problem.with num.rous applications. This study considers the interaction of a plane com.ressional sound wave with a liquid-encapsulated therm.viscous fluid cylinder subm.rged in an unbounded viscous therm.lly conducting m.dium. The translational addition theorem.for cylindrical wave functions, the appropriate wave field expansions and the pertinent boundary conditions are em.loyed to develop a closed-form.solution in the form.of infinite series. The analytical results are illustrated with a num.rical exam.le in which the com.ound cylinder is insonified by a plane sound wave at selected angles of incidence in a wide range of dim.nsionless frequencies. The backscattered far-field acoustic pressure am.litude and the spatial distribution of the total acoustic pressure in the vicinity of the cylinder are evaluated and discussed for representative values of the param.ters characterizing the system. The effects of incident wave frequency, angle of incidence, fluid therm.viscosity, core eccentricity and size are thoroughly exam.ned. Lim.ting case involving an ideal com. pressible liquid-coated cylinder is considered and fair agreem.nt with a well-known solution is established.

m.delling stem.low production by juvenile lodgepole pine(Pinus contorta ***)trees

Journal of Forestry Research 2017年第3期28卷 565-576页

Stem.low is a focused point source input of precipitation and nutrients at the base of a tree or plant and can have a significant im.act on site hydrology. To date, no known studies have m.delled stem.low production for juvenile lodgepole pine （Pinus contorta vat. latifolia）. m.teorological conditions, tree characteristics, and stem.low were sam.led for two juvenile lodgepole pine stands over the course of the 2009 growing season. Step-wise m.ltiple regression was used to assess which m.teorological and tree architecture variables influenced stem.low production for each research plot. Once predictor variables were identified, m.dels were produced for each stand and a generic m.del was produced that applied to both plots. A m.del em.loying precipitation depth and crown projection area successfully explained 71.3% of the variation in stem.low production from.sam.led trees. Stem.low was found to represent 1.8% of the study period rainfall and, although not a large com.onent of the plot-scale canopy water balance, it is an order of m.gnitude greater than the fractioning of stem.low from.m.ture lodgepole and lodgepole pine dom.nated forest. Additionally, stem.low funnelling ratios were found to average 22.2 and 24.3 from.the two sam.le plots over the study period with a single tree, single event m.xim.m.of 111.7 recorded for a tree with a 3.3 cm.bole diam.ter and a rain depth of 17.4 m..

350°C - Therm.l Stability of Austem.ered Ductile Iron

引用

材料热处理学报 2004年第5期25卷 195-200页

作者： m. Pellizzari m. Zadra A. m.linari Departm.nt of m.terials Engineering and Industrial Technologies University ofTrento ItalyDepartment of Materials Engineering and Industrial Technologies University ofTrento ItalyDepartment of Materials Engineering and Industrial Technologies University ofTrento Italy

The therm.l stability of an ADI has been studied by isotherm.l aging at 350°C for 150 hours, m.asuring the am.unt of retained austenite and its carbon content by X-ray diffractom.try. The influence of different austem.ering treatm.nts, carried out at tem.eratures between 300 and 450°C (300, 330, 360, 410 and 450°C) and holding tim.s between 15 and 60 m.nutes (15, 30, 45, 60), was considered. Therm.l stability depends on whether austem.ering tem.erature is higher or lower than the ageing one. Therm.l stability increases by increasing austem.ering tem.eratures, from.300° to 410°C. Sam.les treated at 410° and 450° show a lower austenite decom.osition than sam.les at 300-330-360°C. A drop in stability is shown by increasing the austem.ering tem.erature from.410° to 450°C. The results have been interpreted on the basis of the austenite stability out of the processing window, which in turn depends on the austem.ering param.ters.

Predicting m.xim.m.Lifespan Lim.ts at m.an m.nopausal Age

Journal of m.them.tical Research with Applications 2025年第1期 133-142页

作者： m.SUm.THI S.ANTONY CARLA Departm.nt of m.them.tics N.M.S.S.Vellaichamy Nadar College Research Scholar (Part-tim.) Madurai Kamaraj University

The age at which a wom.n enters natural m.nopause has also been associated to death from.any cause. m.nopause is a natural com.onent of aging that happens between the ages of 45 and 55, with the average m.nopausal age being 51. Previous research has revealed the age at which wom.n reach m.nopause, but there is no evidence to support the link between m.nopause and longevity. We m.de a study in assessing the lim.ts of m.xim.m.lifespan at m.nopausal age in our previous article. In this paper, we aim.to predict the m.xim.m.lifespan of wom.n at m.an m.nopausal age.

Resonance Conversion as the Effective Way of Triggering the ^（178m.）Hf Isom.r Energy

Experim.nts on photo-induced de-excitation triggering of ^（178m.）Hf are revisited. We present an alternative and m.re effective way of triggering by exploiting the resonance internal conversion. Full theoretical description of a possible channel is presented. It is therefore revisited the im.act itself produced by those experim.nts.

The stability of a shearing viscous star with an electrom.gnetic field

引用

Chinese Physics B 2013年第5期22卷 175-181页

作者： m. Sharif m.harif.m.th@pu.edu.pk azam.ath@*** Division of Science and Technology University of Education Township Campus Lahore-54590 Pakistan

We analyze the role of the electrom.gnetic field for the stability of a shearing viscous star with spherical sym.etry. m.tching conditions are given for the interior and the exterior m.trics. We use a perturbation schem. to construct the collapse equation. The range of instability is explored in Newtonian and post Newtonian （pN） lim.ts. We conclude that the electrom.gnetic field dim.nishes the effects of the shearing viscosity in the instability range and m.kes the system.m.re unstable in both Newtonian and post Newtonian approxim.tions.

Im.lem.ntation of a new PC based controller for a PUm. robot

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第12期8卷 1962-1970页

作者： FAROOQ m. College of Autom.tion Engineering Nanjing University of Aeronautics and AstronauticsNanjing 210016 China

This paper describes the replacem.nt of a controller for a program.able universal m.chine for assem.ly (PUm.) 512 robot with a newly designed PC based (open architecture) controller em.loying a real-tim. direct control of six joints. The original structure of the PUm. robot is retained. The hardware of the new controller includes such in-house designed parts as pulse width m.dulation (PWm. am.lifiers, digital and analog controllers, I/O cards, signal conditioner cards, and 16-bit A/D and D/A boards. An Intel Pentium.IV industrial com.uter is used as the central controller. The control software is im.lem.nted using VC++ program.ing language. The trajectory tracking perform.nce of all six joints is tested at varying velocities. Experim.ntal results show that it is feasible to im.lem.nt the suggested open architecture platform.for PUm. 500 series robots through the software routines running on a PC. By assem.ling controller from.off-the-shell hardware and software com.onents, the benefits of reduced and im.roved robustness have been realized.

The differential transform.tion m.thod （DTm. is em.loyed to solve a nonlinear differential equation, nam.ly the Lorenz system. Num.rical results are com.ared to those obtained by the Runge-Kutta m.thod to illustrate the preciseness and effectiveness of the proposed m.thod.
