OASIS is a distributed RBAC implementation with many extensions. Sound policy design will permit OASIS to protect the distributed resources whose access privileges it controls. However, through operating in a distributed environment, the underlying OASIS infrastructure is open to a number of potential attacks. This paper identifies three main classes of such attack and introduces techniques to ...

OBJECTIVE To determine modifiable risk factors and incidence of obstetric anal sphincter injury (OASIS) in primiparous women. STUDY DESIGN We performed a population-based retrospective cohort study, using data from the Danish Medical Birth Registry. The population consisted of primiparous women with a vaginal delivery in the time period 2000-2010. Univariable and multivariable logistic regres...

OASIS is a Language for the Specification of Object Oriented Conceptual Models. In OASIS the conceptual schema of an information system is represented as a society of concurrent objects interacting with one another. Animation of such models in order to validate the Specification of Information Systems is an interesting topic. We have developed a basic Execution Model for OASIS Specifications. T...

Determine which Membership Category and Dues [1] level is appropriate for your organization. Review OASIS Policies and Procedures [2] to learn about OASIS governance and expectations. Identify a Primary Representative [3] who will be responsible for your organization's overall participation and a Billing Contact. Optionally, you may also identify an Official Notice Contact (usually your legal c...

A population evolving in an inhomogeneous environment will adapt differently to different areas. We study the conditions under which such a population can maintain adaptations to a particular region when that region is not stationary, but can move. In particular, we consider a haploid population living near a moving favorable patch ("oasis") in the middle of a large "desert." At one genetic loc...

OBJECTIVE The authors aimed to (1) formally represent OASIS-B1 concepts using the Logical Observation Identifiers, Names, and Codes (LOINC) semantic structure; (2) demonstrate integration of OASIS-B1 concepts into a concept-oriented terminology, the Medical Entities Dictionary (MED); (3) examine potential hierarchical structures within LOINC among OASIS-B1 and other nursing terms; and (4) illus...

OBJECTIVES We sought to determine the rates of obstetrical anal sphincter tears (OASIS) between types of obstetrical care providers at Kingston General Hospital (KGH) and in Ontario via the Better Outcomes Registry Network (BORN). METHODS This cross-sectional study collected patient, demographic, and delivery data from all vaginal deliveries at KGH from June 2011 to June 2014 and all vaginal ...

The network bottleneck incurred by big data process and transfer has increasingly become a severe problem in today's data center and cloud storage. Exploring and exploiting the advantages of both the scalable object storage architecture and intelligent active storage technology are one of the ways to address this challenge. In this talk, we present the design and performance evaluation of Oasis...

This paper offers an improved model of the OASIS system, which is a distributed domain specific search system in the Internet. The main thrust of our approach is to connect OASIS servers with a high-speed network based on ATM technology. This high-speed network allows communication between servers. Here we present methods of connecting OASIS servers with the ATM network. Obtained results indica...
