According to the non-linear and non-stationary characteristics of vibration signal in roller grinding manufacturing process, background signals, namely when grinder is idling during contact grinding, are collected separately, decomposed into multiple by method CEEMDAN modal decomposition. Then several components removed correlation analysis. Finally, denoised analyzed wavelet threshold denoisin...

BACKGROUND Study of the vascular response to stent implantation has been hampered by difficulties in sectioning metal and tissue without distortion of the tissue stent interface. The metal is often removed before histochemical processing, causing a loss of arterial architecture. Histological and immunohistochemical sections should be 5 microns with an intact tissue stent interface. OBJECTIVES...

368 blood and Carcass randomly sampled from slaughtered animals for detection Toxoplasmosis. The blood samples were examined for existence Infection by serological method (Dye test) and the tissue samples from different parts of carcass including skeletal muscle, diaphragm, heart, liver and lymphnode, which ground in an electric grinder and digested by pepsin. Bioassay technique and inoculated...

background: echinocuccus granulosus, the causative agent of cystic echinococcosis has long been recognized as having a high degree of genetic divergence. the strains characterization seems to be essential for the establishment of a preventive and control strategy in every endemic area. using dna based methods for strain /genotype characterizations of e. granulosus have some difficulties, especi...

Millet idli batter was prepared from decorticated little millet and black gram (2:1, 3:1 and 4:1) using wet grinder with adequate amount of water and salt (1-2%). The different blends were allowed for fermentation at 0, 2, 4, 6, 8, 10, 12, 14 and 16 h, separately. The batter property viz. bulk density, percent volume rise, pH and titrable acidity was studied for different fermentation time. Idl...

Path planning for a robot-assisted surface finishing system with an active torque controller is presented in this paper. We utilize a dexterous manipulator to attain the desired position and orientation in three-dimensional space during finishing processes. A single-axis active controller consists of a dc motor and a software observer is attached to the robot wrist and used to actuate a pneumat...
