Clustering in big data considers a critical mining and analysis technique. There are problems with adapting clustering algorithms to large amounts of data, along new challenges brought by data. As the size is up petabytes methods have high processing costs, challenge how overcome this issue utilize techniques for promptly. The purpose work investigate history advancement platforms handle issues...

COOPERATIVE ROBOTS Mark E. Cambron and Koji Fujiwara Center for Intelligent Systems Vanderbilt University Nashville, TN USA ABSTRACT This paper describes a robotic system for feeding the physically challenged. A prototype intelligent robotic aid system called the ISAC (Intelligent Soft Arm Control) is being developed for the service sector. Recently we have begun to integrate a HERO 2000 mobile...

R concern has been raised over the existence of obvious taxonomic biases in contemporary literature on ecology, evolution, and conservation biology (Bonnet et al. 2002, Stein et al. 2002, Clark and May 2002a, 2002b). For example, Bonnet and colleagues (2002) show that that an apparent, albeit subliminal, bias toward homeothermic (endothermic) fauna affords research on these groups greater publi...

Today’s Push-to-talk (PTT) services are infrastructure based and require stable end-to-end paths for successful communication. However, users with PTT enabled mobile devices may roam in challenged environments where infrastructure is not available. In such cases the traditional PTT services may exhibit poor performance or even fail completely. Delay-Tolerant Networking (DTN) is a research area ...

Many network links in developing regions are low-bandwidth or intermittent. In addition to the inherent connection constraints, web browsing over these networks is an extremely painful experience due to inappropriate cache design. A single cache miss during browsing may cause a stall on the order of minutes or even hours. To improve web cache performance, we propose a new model of web caching p...

Enabling universal Internet access is one of the key issues that is currently being addressed globally. However the existing Internet architecture is seriously “challenged” to ensure universal service provisioning. This short paper puts forth our vision to make the Internet more accessible by architecting a universal communication architectural framework combining two emerging architecture and ...

This paper presents a discussion of issues that need to be addressed for processing relational queries in distributed environments where the connectivity is unstable and is changing continuously. Query processing over data across nodes that are collecting information is an example of such an environment. Traditional distributed query processing techniques need to be extended to accommodate new ...

The motor cortex is often considered the main controller for movement, but a new study shows that well-trained paw movements can be performed with equal precision after lesions of the entire motor cortex; the motor cortex is, however, required for learning a new task in naïve animals.

The need for routine diagnostic tests and procedures needs to be challenged in medical practice, because of continuous pressure to reduce the costs of health care systems. If costs can be minimized by avoidance of routine tests, more sources can perhaps be directed to new advanced diagnostic and therapeutic procedures. This challenge is important particularly in cardiology, because while new di...
