multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...
This paper presents the analysis of vibration control of a laminated composite beam that including magnetostrictive layers. The formulation of problem is presented based on the shear deformation beam theory. For vibration suppression, the velocity feedback control with constant gain distributed is considered. Navier's method is applied to analyze the solution of vibration suppression of laminat...
an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...
In this paper, mini-channel type evaporator which is new in mobile air conditioning (MAC) or automotive air conditioning (AAC) systems is thermally modeled. The performance of mini-channel evaporator is also compared with the laminated evaporator which is being currently used in automotive industries. The mini-channel evaporator was constructed of two rows of parallel flow mini-channel tubes...
The purpose of this paper was modeling and mechanical analysis of the biodegradable biphasic calcium phosphate/silk (BCP/Silk) laminated composite bone plate for fractured tibia healing; to this aim,ABAQUS 6.13 was employed for modeling and mechanical analysis. First, the tibia bone was considered based on the anthropometric measurements of an average person as a two-layer cylinder; the inner p...
In the construction of polarization beam-splitters (PBS) and switches a structure can be employed, that is based on the birefringence of periodically laminated dielectric thin films [2,7]. In this work we derive an estimate of the split angle in laminated polarization splitters behaving as negative uniaxial crystals, in the case of oblique incidence. This analysis has been applied to an artific...
This paper addresses an inverse approach to estimate the frequency-dependent Young’s modulus of a viscoelastic polymer layer in a laminated structure. The Young’s modulus is parameterized by a fractional derivative model and examined from a Bayesian perspective with the consideration of measurement and modeling uncertainties. The probabilthe use of Markov Chain Monte Carlo sampling methods. The...
The focus of this research is the stress laminated timber cellular deck. The testing program has involved application of loads that modelled both the design serviceability and design ultimate conditions, and identified slip and load redistribution mechanisms, which occur at the limit state of linear composite behaviour. This paper presents a summary of the results of this testing and discusses ...
cystic hydatid disease is caused by cystic larval (metacestode) stages of echinococcus granulosus. this parasite can potentially occur all over the world especially in mediterranean and middle east countries and some parts of africa, latin america and china which have major foci of human infections. the cyst wall of metacestodes consists of inner, middle and external layers. to date, little att...
This paper describes work on alternative technologies associated with an urban maglev system that employs Halbach arrays of permanent magnets onboard a moving vehicle to induce levitating currents in a stationary “track”. A laminated structure, composed of stacks of thin conducting sheets, has several advantages over a litz-cable ladder as the track. Modeling and experimental results for the la...
