Geophysical test of the universality of free-fall
We point out that the universality of free-fall can be tested by observing surface-gravity changes of the Earth. The Earth’s inner core is weakly coupled to the rest part of the Earth by mainly gravitational forces. If there were a violation of the universality of free-fall, because of their different chemical compositions and/or of different mass fractions of binding energies, the inner core a...
متن کاملconstruction and validation of a computerized adaptive translation test (a receptive based study)
آزمون انطباقی رایانه ای (cat) روشی نوین برای سنجش سطح علمی دانش آموزان می باشد. در حقیقت آزمون های رایانه ای با سرعت بالایی به سمت و سوی جایگزین عملی برای آزمون های کاغذی می روند (کینگزبری، هاوسر، 1993). مقاله حاضر به دنبال آزمون انطباقی رایانه ای برای ترجمه می باشد. بدین منظور دو پرسشنامه مشتمل بر 55 تست ترجمه میان 102 آزمودنی و 10 مدرس زبان انگلیسی پخش گردید. پرسشنامه اول میان 102 دانشجوی س...
Quantum free-energy calculations: A three-dimensional test case
An optimized integration scheme for calculating vibrational-rotational partition functions by the Fourier path-integral method, as presented in the previous paper [R. Q. Topper and D. G. Truhlar, J. Chem. Phys. 97, 3647 (1992)] is applied to a three-dimensional test case involving the coupled vibrational and rotational motions of a diatomic HCI molecule in Cartesian coordinates. Converged parti...
متن کاملA Review on Finite Element Analysis of Free Fall Drop Test on Mobile Phone
Present paper discusses the working methodologies used for drop test. Engineers widely used physical testing method to investigate the behaviour of cellular phone during drop test. It is very costly, time consuming and complex. Finite element analysis provides numerical models without spent so much money on physical testing methods. Drop test simulation is one of the important tool uses for the...
متن کاملDetection-loophole-free test of quantum nonlocality, and applications.
We present a source of entangled photons that violates a Bell inequality free of the "fair-sampling" assumption, by over 7 standard deviations. This violation is the first reported experiment with photons to close the detection loophole, and we demonstrate enough "efficiency" overhead to eventually perform a fully loophole-free test of local realism. The entanglement quality is verified by maxi...
