A Self-Adaptive IoT-based Approach for Improving the Decision Making of Active Surgical Robots in Hospitals
In recent years, surgical robots have become instrumental tools for assisting surgeons in performing complex surgical procedures in hospitals. Unlike conventional surgical methods, robotic systems help surgeons, for example, to perform minimally invasive surgical procedures while enhancing the precision and control of ...

Compressive Sensing Based Opportunistic Protocol for Throughput Improvement in Wireless Networks
A key feature in the design of any MAC protocol is the throughput it can provide. In wireless networks, the channel of a user is not fixed but varies randomly. Thus, in order to maximize the throughput of the MAC protocol at any given time, only users with large channel gains should be allowed to transmit. In this pape...

On-line Learning of Binary Lexical Relations Using Two-dimensional Weighted Majority Algorithms
We consider the problem of learning a certain type of lexical semantic knowledge that can be expressed as a binary relation between words, such as the so-called sub-categorization of verbs (a verb-noun relation) and the compound noun phrase relation (a noun-noun relation). Specifically, we view this problem as an on-li...
