In order to overcome the loss of performances issue when scaling resonant sensors down to NEMS, it proves extremely useful to study the behavior of resonators up to large displacements and hence high nonlinearities. A comprehensive nonlinear multiphysics model based on the Euler-Bernoulli equation which includes both mechanical and electrostatic nonlinearities in the case of a capacitive doubly...

Many physics experiments are designed to search for some rare, previously unseen phenomenon which would leave a distinctive event signature in the detector. Generally, there are one or more “background” processes which can mimic the signature, so that detecting the new phenomenon is a matter of observing significantly more events than would be expected from background processes. However, the Ba...

Plasticity-induced, roughness-induced and oxide-induced crack closures are reviewed. Special attention is devoted to the physical origin, the consequences for the experimental determination and the prediction of the effective crack driving force for fatigue crack propagation. Plasticity-induced crack closure under plane stress and plane strain conditions require, in principle, a different expla...

A rich phenomenology could be studied in the misfocused vision through a pinhole or a system of pinholes punched on a black cardboard. Some of the observations we describe here can be also found in the ancient Literature. In this paper, we aim to rediscover and discuss some particular effects in light of a new perspective which provide an answer to interesting zero-cost experiments. In particul...

This paper provides an overview of the important physical phenomena necessary for the determination of effective thermal conductivity of nanofluids. Through an investigation, a large degree of randomness and scatter has been observed in the experimental data published in the open literature. Given the inconsistency in these data, it is impossible to develop a comprehensive physical-based model ...

A traditional trend toward scientific explanation aimed to provide a single account of the nature of explanation. On the other hand, a recent attitude toward mathematical explanations of physical phenomena is to go ‘pluralist’ and consider that what makes something a good explanation can vary from case to case, i.e. there are different kinds of explanation which cannot be captured through a sin...

reasons for assigning to them a merely morbid and physical origin ; (4) to suggest means of prevention and cure. (1) By genuine remorse, according to the definition of it given by Clarendon, Bishop Hall, &c., and derived from the etymology of the word, is meant, " the keen pain or anguish excited by a sense of guilt; compunction for a vicious, or sinful act committed." Dr. Thomas Brown describe...

theories of modern physics, and the increasingly mathematical arguments used in their development, has led some to see the success of modern physics to seem mysterious or even magical. Looking at the development of equations in quantum theory, Steiner (1998) has argued that as a result of their being developed using various kinds of mathematical, rather than physical, analogy, their significant...
