Silicon carbide powder (SiCp) was milled in a high energy ball mill in 300 rpm for 8 hrs. The wet milling media was tungsten balls (WC) in chemical compound Toluene (C6H6-CH3).The milled powder then characterized by Atomic Force Microscope (AFM) to study topography and particle size analyzer.
The automatic detection of malignant cells in soft tissues with the help of medical images assists the pathologists in histopathology diagnosis to confirm cancer. This system helps pathologists to improve the accuracy, efficiency to detect malignancy and to minimize the inter-observer variation. In addition, the method may help us to analyze the morphometric and staining characteristics of the cells...
Carbon nanotubes (CNTs) are interesting materials in view of their wide range of applications in hydrogen storage, chemical sensor, catalytic support, biochemical applications and field emission. Such tremendous applications are due to unique geometry, high chemical stability, high mechanical strength and excellent thermal and electrical conductivity. Various synthesis methods such as arc discharge,...
A commercial purity Aluminum was prepared through powder metallurgy technique and deformed by extrusion at 560°C and then subjected to recrystallization treatment at the temperature of 600°C with varied time intervals to follow the kinetics of recrystallization. The samples obtained were examined for the metallurgical structure and then photomicrography was carried out. The results obtained from the...
A magneto rheological fluid (MR fluid) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. Importantly, the yield stress of the fluid when in its active (“on”) state can be controlled very accurately by varying the magnetic field intensity. The upshot...
In this paper, a system for diagnosis of oral cancer has been developed using Gabor filter technique. The microscopic images of immunohistochemical staining of β-catenin expression are segmented using a bank of Gabor filter tuned to different spatial frequencies and orientation in order to decompose the image into number of filtered image to obtain feature image. To produce segmented image Fuzzy C-means...
