In this paper, the general governing equations of three-dimensional vibrations of an Euler-Bernoulli Beam under influences of system dynamics are derived by the Hamiltonian method. Then two fundamental cases of a cantilever beam and a rotating beam are considered. The conventional methods for vibration suppression debit to expenses and make new problems such as control spillover because they ar...

oxides of nitrogen are the major emission from a diesel engine. it is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of no is promoted. various techniques are therefore employed to reduce the nox emission like egr, scr, etc. in this present work a rotating injector is a tec...

rotating machinery is the most common machinery in industry. the root of the faults in rotating machinery is often faulty rolling element bearings. this paper presents a technique using optimized artificial neural network by the bees algorithm for automated diagnosis of localized faults in rolling element bearings. the inputs of this technique are a number of features (maximum likelihood estima...

entropy generation in an unsteady hydromagnetic couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the newton's law of cooling. a numerical solution for governin...

objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

OBJECTIVES Existing research has documented that shiftwork consequences may depend on the shift system parameters. Fast rotating systems (1-3 shifts of the same kind in a row) and day work have been found to be less disruptive biologically and socially than slower rotating systems and afternoon and night work. The aim of this study was to compare day workers and shift workers of different syste...

1. Introduction Several kinds of RF (radio frequency) radiated immunity/susceptibility test methods have been proposed, and put to practical use. The test methods using transverse electromagnetic (TEM) devices such as TEM cell and GTEM cell have already been standardized. By using these methods, the immunity/susceptibility characteristics to the electromagnetic (EM) field in a fixed direction o...
