This paper presents a probabilistic approach based on polynomial chaos expansion, in order to provide accurate explicit approximation of the structural response to be considered in the limit state function. The main difficulties in this approach are related to the calculation of the expansion coefficients which are defined by multi-dimensional integrals. As an alternative to the quadrature meth...

This paper provides an exact approach for free transverse vibration analysis of a simply supported non-uniform Euler-Bernoulli beam with an arbitrary number of concentrated cracks. The equation of motion is normalized and written based on a set of dimensionless parameters. The general solution is obtained based on the Bessel functions. The differential equation is modified to include cracks. Th...

Ion beam modification to effect ion beam mixing without changing morphology was investigated as a means to improve the electrochemical performance of Ge thin film electrodes for rechargeable Li batteries. As a result of a minimum tenfold increase in the strength of adhesion of the Ge film to the current collector (substrate), the ion beam-mixed electrodes exhibited stable specific capacities of...

— In a network, for remote accessing to a database server (DB Server) user usually has an account with a username and a password. But in fact, the password can be lost, cracked, stolen and the authentication process can be attacked (man-inthe-middle attack...). Current approach for BioPKI system based on physiological characteristics of persons, known as biometrics, provide solutions to securit...

OBJECTIVE This study aimed to investigate the effects of enrichment resources (a perch, dustbath, and nest) layout in furnished laying-hen cages (FC) on exterior quality of eggs. METHODS One hundred and sixty-eight (168) Hy-Line Brown laying hens at 16 weeks of age were randomly distributed to four treatments: small furnished cages (SFC), medium furnished cages type I (MFC-I), medium furnishe...
