Abstract: A system and method for handling a request from a client device to access a service from a server. The method comprises receiving a request from a user using a client device to access a service from a server. The request is received by a network traffic management device having a local external access management (EAM) agent. The EAM agent directly communicates with an EAM server that provides authentication policy information of a plurality of users able to at least partially access the server. User credential information is sent from the EAM agent to the EAM server, whereby the EAM agent receives access policy information of the user from the EAM server. The system and method selectively controls access of the user's request to the server in accordance with the received access policy information at the network traffic management device.

Abstract: A method and apparatus is provided to generate two X-ray projection images, using different focal-spot sizes in the X-ray source. The large and small focal-spot images have different image qualities (e.g., different signal-to-noise rations (SNR) and different resolution). The two images are combined, in either the spatial or frequency domains, to generate a combined image, exhibiting the best attributes of the constitutive small and large focal-spot images. In the spatial domain, change regions and uniform regions are determined based on spatial variations within the images, and the superposition generating the combined image weights the small focal-spot image more in the change regions and the large focal-spot image more in the uniform regions. In the frequency domain, the combined image superimposes low-frequency components of the large focal-spot image with high-frequency components of the small focal-spot image.
