DICOM (Digital Imaging and Communication in Medicine) is a standard for image data transmission medical purpose hardware commonly used viewing, storing, printing transmitting images. As part of the way that transmits files, PACS (Picture Archiving System) platform, Dicoogle, has become one most in-demand processing viewing platforms. However, Dicoogle architecture does not guarantee information...

We present a new access control mechanism for P2P networks with distributed enforcement, called P2P Access Control System (PACS). PACS enforces powerful access control models like RBAC with administrative delegation inside a P2P network in a pure P2P manner, which is not possible in any of the currently used P2P access control mechanisms. PACS uses client-side enforcement to support the replica...

Models capturing the growth of polycyclic aromatic compounds (PACs) and nanoparticles in combustion have always faced a large degree uncertainty due to paucity detailed direct experimental validation. In particular, data on molecular structures, chemical composition, size, cross-linking, aliphatic chains is still very limited. past few years, we developed an atomistic code, SNapS2, that models ...

introduction: health information systems have the potential of improving the quality of healthcare and treatment procedures and supporting the physicians in their clinical diagnoses. nowadays, evaluating the usability is widely accepted as a crucial factor in the acceptance and success of the interactive healthcare systems. the present study aimed to evaluate the usability of ulite software bas...

PACS (Personal Access Communications System) has been recently standardized as a TDMA air interface for microcel-lular networks operating in the PCS band (1850-1990 MHz). In order to meet performance requirements, the standard suggests use of a simple dual diversity antenna system at the Radio Port (base station) and Subscriber Unit (mobile). Space-time signal processing can be used to enhance ...
