China's social medical security system includes medical insurance for urban workers, medical insurance for urban residents, new type of rural cooperative medical care and medical assistance. To solve the problem of inadequate and unaffordable medical services, the government has provided a large number of public financial subsidies for this system. But similar to America, China's population aging...
Brain tumor segmentation is an important image processing step in diagnosis, treatment planning, and follow-up studies of Glioblastoma (GBM). However it is still a challenging task due to varying in size, shape, location, and image intensities within and around the tumor. In this paper, we propose a new brain tumor segmentation method for T1-weighted MR brain images based on an improved level set...
This paper has presented and designed a four-channel video data system of reception, extraction, display and switch based on the DE2-70 development and education board and the development environment of embedded operating system μClinux. First, it received the video data packets, which were 640×480 resolution and RGB format coming from the four cameras in front-end through the router on network, and...
A novel thermal controlled optical attenuator based on symmetric dielectric-loaded surface plasmon polariton (SDLSPP) waveguide is proposed and theoretically analyzed in this work. The mode effective indices, propagation lengths, the temperature dependent characteristic are analyzed using a finite-element method (FEM). Such device can be controlled by low driving power and shows excellent tunability...
