In this paper an issue of local damage detection in a rolling element bearing is discussed. The bearing operates in a hummer crusher, thus the vibration signal acquired on the housing contains a lot of impacts that originate in various sources. In the case of local damage detection it is crucial to find a set of cyclic impulses in the signal. These impulses are informative, in spite of impulses...

We report the diffusion coefficient and viscosity of popular rigid water models: two non-polarizable ones (SPC/E with three sites, and TIP4P/2005 with four sites) and a polarizable one (Dang-Chang, four sites). We exploit the dependence of the diffusion coefficient on the system size (Yeh and Hummer 2004 J. Phys. Chem. B 108 15873) to obtain the size-independent value. This also provides an es...

The connection between work and changes in the Hamiltonian for a system with a time-dependent Hamiltonian has recently been called into question, casting doubt on the usefulness of the Jarzynski equality for calculating free energy changes. In this paper, we discuss the relationship between two possible definitions of free energy and show how some recent disagreements regarding the applicabilit...

Vehicle externality costs include emissions of greenhouse and other gases (affecting global warming and human health), crash costs (imposed on crash partners), roadway congestion, and space consumption, among others. These five sources of external costs by vehicle make and model were estimated for the top-selling passenger cars and light-duty trucks in the U.S. Among these external costs, those...

Trapeziometacarpal joint (TMCJ) of the thumb is an unstable anatomically and depends on integrity normal functionality ligaments to prevent dislocation. Dislocation or subluxation trapezio-metacarpal generally appears more often as injuries accompanied with intraarticular fracture base first metacarpal trapezium. Isolated dorsolateral trapeziometacarpal osteoarthritis rather than traumatic lesi...

The free energy profile obtained from the WHAM procedure is a function of the chosen reaction coordinate, with all other degress of freedom integrated out. This implies that these orthogonal degrees of freedom are adequately sampled in each window, which might require much longer timescales than typical window lengths if they feature local minima separated by high free energy barriers. In addit...

Carbon-based nanoparticles, particularly graphite nanoformulations have seized plenty of fancies currently, groundbreaking development is being made with these formulations and the potentials are limitless. Graphene Oxide has a huge molecular structure, carries many functional groups together hydroxyl, carboxylic, carbonyl epoxide companies which best for esterification amidation reactions. on ...
