“Cognitive” radial access

Catheterization and Cardiovascular Interventions, 2017
Key Points Using observational data, acute outcomes for type C lesions appear comparable between radial and femoral access. Radial access associated with longer procedures and greater radiation exposure In‐hospital complications in propensity matched patients were not significantly different regardless of access site

Telerehabilitation, cognition and user-accessibility

NeuroRehabilitation, 2003
Survivors of traumatic brain injury (TBI) often experience cognitive and physical impairments. The aims of this study were to: 1) build an internet-based, “Virtual Rehabilitation Center” (VRC) that provides rehabilitation, education and support services to individuals with TBI; and 2) to determine the relationships between the nature and severity of ...

Cognitive access algorithms for multiple access channels

2013 IEEE 14th Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2013
This paper considers a multiple access fading channel where each terminal has a different belief about the channel states and adapts its transmission policy to the belief. In this setting, frequency division multiple access (FDMA) and channel aware random access (RA) are two special cases.

Cognitive multiple access networks

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
A cognitive radio can sense the transmission of other users in its environment and possibly extract the corresponding messages. It can use this information to transmit over the same channel while reducing interference from, and to other users. In this paper, we define inter/intra-cluster competitive, cooperative, and cognitive behavior in wireless ...

Socio-Cognitive Accessibility to Places

2016
Accessibility is a core concept in human geography when it comes to geographical mobility. And yet residential mobility is never addressed in terms of geographical accessibility! Choices, preferences, and decision-making processes are generally at the heart of descriptive and explanatory models of residential mobility.

Cognitive access control in cognitive heterogeneous networks

2009 IEEE International Conference on Communications Technology and Applications, 2009
In this paper a framework and cognitive process behavior model for a novel type of adaptive data network was proposed. Furthermore, access network selection and admission control mechanisms are integrated into a procedure defined as access control. The access control mechanism is based on cognitive process, and enables all network elements involved to ...
