Access control is a significant issue in any secure database system. In this paper, we develop a logic programming based approach for temporal decentralized authorization administration in which users can be delegated, granted or forbidden some access rights for restricted periods of time. Three

In this article we propose a standard for role-based access control (RBAC). Although RBAC models have received broad support as a generalized approach to access control, and are well recognized for their many advantages in performing large-scale authorization management, no single authoritative

Beyond credentialing in physician selection: Application of an instrument that measures behavioral aptitude

Abstract—Sensorized instruments that accurately measure the interaction forces (between biological tissue and instrument end-effector) during surgical procedures offer surgeons a greater sense of immersion during minimally invasive robotic surgery. Although there is ongoing research into force measurement involving surgical graspers little corresponding effort has been carried out on the measurement of forces between scissor blades and tissue. This paper presents the design and development of a force measurement test apparatus, which will serve as a sensor characterization and evaluation platform. The primary aim of the experiments is to ascertain whether the system can differentiate between tissue samples with differing mechanical properties in a reliable, repeatable manner. Force-angular displacement curves highlight trends in the cutting process as well the forces generated along the blade during a cutting procedure. Future applications of the test equipment will involve the assessment of new direct force sensing technologies for telerobotic surgery. Keywords—Force measurement, minimally invasive surgery, scissor blades, tissue cutting. I.
