Cognitive Radio (CR) is a key technology for improving the utilization level of the overall radio spectrum in wireless communications. It is able to sense and change its transmission and reception parameters adaptively according to spectrum availability in different spectrum channels. The Cognition Cycle (CC) is a state machine that is embodied in each CR host that defines the mechanisms related to...
An intelligent inhabited environment applying interconnected embedded agents by network has intelligent reasoning, planning learning, and control capabilities. Thermal and light comforts are two major control objectives for the environment to deal with using data-driven control method. Practically, dynamic association level of agents should be learned from online data with three reasons: changing...
We deployed 72 sensors of 10 modalities in 15 wireless and wired networked sensor systems in the environment, in objects, and on the body to create a sensor-rich environment for the machine recognition of human activities. We acquired data from 12 subjects performing morning activities, yielding over 25 hours of sensor data. We report the number of activity occurrences observed during post-processing,...
This paper introduces a novel vision for further enhanced Internet of Things services. Based on a variety of data - such as location data, ontology-backed search queries, in- and outdoor conditions - the Prometheus framework is intended to support users with helpful recommendations and information preceding a search for context-aware data. Adapted from artificial intelligence concepts, Prometheus...
Motivations for the use of automation technologies in the residential domain are manifold. Besides efficiency considerations for energy intensive areas such as heating and air-conditioning, increased comfort, smart home care, and ambient assisted living are key motives. A key challenge of future smart homes is to find a good balance between these goals and not to treat them in an isolated fashion...
Emotions are a ubiquitous component of motivation and learning; therefore it is desirable for intelligent tutors the incorporation of affective models. We developed an affective behavior model for intelligent tutoring systems with base on intuition, literature and teachers' expertise. The model selects a tutorial action based on the knowledge and affective state of the student. We conducted a study...
The paper considers agent and data mining interaction in ubiquitous environment and analyses some specific, for such environment, knowledge discovery tasks. It focuses on agent-based applications organized as overlay network of autonomous agents set up on top of ubiquitous environment composed overlay network of FIPA compliant P2P agent platform instances set up on top of the P2P communication service...
Summary form only given. Recent advances in ubiquitous computing, autonomic computing, and artificial intelligence have led to a desire to better support user-oriented tasks by placing more intelligence in the computing infrastructure. This infrastructure helps mediate between computing resources and legacy applications on the one hand, and a user's high-level goals on the other hand. In this talk...
Reacting to unpredictable situations is one of the main problems in technical automation. This article introduces two developed framework for decision units for embodied autonomous agents. The models are compared to an existing architecture, the BDI architecture. The basis of the described model is using psychoanalytical concepts. Drives, emotions and wishes are the basics that build a reaction due...
Our environment is complex and the amount of information is exceeding any volume being manually manageable by humans. Information needs to be adjusted and personalized to be of avail to each individual user. In this paper, a novel software system is described achieving content personalization with high quality and in an automatic manner. The approach taken for creating new personalized services is...
