It is well known from physiological studies that the level of human attention for adult individuals rapidly decreases after five to twenty minutes [1]. Attention retention for a surveillance operator represents a crucial aspect in Video Surveillance applications and could have a significant impact in identifying relevance, especially in crowded situations. In this field, advanced mechanisms for selection...
This paper presents the development of an adaptive gap filler for Digital Terrestrial Television broadcasting. Unlike conventional equipment, which only amplifies and retransmits the desired signal, the proposed system employs cognition principles to analyze the adjacent channels spectrum, thus ensuring the required protection ratio.
This paper presents an autonomous cognitive radio (CR) architecture, referred to as the Radiobot. This model goes beyond adaptive radio systems to exploit the main ingredients of cognition which, in this context, are mainly self-learning and self-reconfiguration. Without any prior knowledge of the RF environment, the Radiobot applies a sequence of increasingly sophisticated processing steps to detect...
We describe a distributed reasoning system called Otto-Mate that is used to detect, reason about, and respond to incidents on a computing network. Events for monitoring computing networks occur at different system levels. Some information might relate to data, some might be operating system specific, some application or service related, some could be network related, and from each there will be compound...
The article explored the relationship between individual cognitive style related with psychological type and transformational-transactional leadership style. After the investigation of 222 leaders, the results indicated: (1) Most of Chinese leaders belong to the cognitive style of sensing, thinking, and judging; (2) the cognitive factors that influence leadership style are: the style about deriving...
In this paper we describe a preliminary modeling and analysis of a unique data set comprising unobtrusive and continuous measurements of gait velocity in the elder participants' residences. The data have been collected as a part of a longitudinal study aimed at early detection of cognitive decline. We motivate these analyses by first presenting evidence that suggests significant relationship between...
