This paper presents an automatic content-based image retrieval (CBIR) system for brain tumors on T1-weighted contrast-enhanced magnetic resonance images (CE-MRI).The key stuart products emcelle tocopherol challenge in CBIR systems for MR images is the semantic gap between the low-level visual information captured by the MRI machine and the high-lev
Abstract Introduction Though animal-related injuries and fatalities have been documented throughout the world, the variety of attacks by wild animals native to rural East Africa are less commonly described.Given the proximity of our northwestern Tanzania hospital to Lake Victoria, Lake Tanganyika, and the Serengeti National Park, and presentation o
Alightweight polymer composite with a broad bandwidth, tunable absorption frequency and multi-functionality is an ideal material for making a radar absorber.In general, composite microcellular foams have many potential applications due to their lightweight, high mechanical properties and monotonous cell structure.In this research, the effect of foa
Certain quantum devices, such as half-wave plates and quarter-wave plates in quantum optics, are bidirectional, meaning that the roles of their input and output ports can be exchanged.Bidirectional devices can be used in a forward mode and a backward mode, corresponding to two opposite choices of the input-output direction.They can also be used in
Optical phased array (OPA) imaging technique, which uses electro-optic modulation to achieve beam steering rather than mechanical scanning, is a raster scanning imaging method with great potential due to read more its noninertia and high speed.However, fabrication imperfection of an OPA causes pre-designed phase modulations not yielding desired ste
