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, 2003Survivors 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), 2013This 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., 2005A 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 ...

Cognitive Accessibility of Indoor Navigation Apps
2023Advances in smartphone technology have made it possible to develop mobile apps that assist people with cognitive or learning disabilities in navigating indoor spaces more easily and independently. This paper reviews the state of the art in smartphone-based indoor navigation for this population and describes a usability trial that was conducted with ...

Socio-Cognitive Accessibility to Places
2016Accessibility 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, 2009In 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 ...
