The influence of the control plane topology to the quality of services offered by the GMPLS network is considered in this paper. Several simulation experiments are prepared to verify this influence. The simulations assume separation of the functional planes of GMPLS and two typical topologies ring and mesh. The GMPLS control plane simulator, prepared by authors, simulate most of the control plane...
Abstract The enormous number of data stored in large, relational databases makes the exploring, querying and reporting processes difficult. The database queries executed on redundant, incoherent, and contextless data may cause erroneous results. The Semantic Web (SW) technology has been considered to solve the problem. In this paper we propose ControlSem - the semantic oriented system architecture...
In this paper we introduce a new framework for the development of context-aware knowledge by integrating the user's digital and physical environment. The developed knowledge can contribute to solve problems and challenges of wireless sensor networks within a context that is described by additional cyber-content. Sensor networks are exposed, intentionally or not, to dynamically changing network structures...
This paper analyses from a psychological standpoint how human and more generally psychological dimensions were taken in consideration by the recent literature related to information technology security. We discuss three main psychologically relevant dimensions such as cognitive hacking, hackers profiling and human errors and distinguish four distinct levels of psychological approaches to information...
The paper presents a prototype of a system which can be used as a therapeutic and educational tool for children with developmental problems. Natural body movements and gestures are used in the system to interact with virtual objects displayed on the screen. Nowadays such systems can be easily built with the use of widely available free software tools for both graphical and vision applications. Such...
Interactions of the human operator with technical equipment are complex. Effects of particular issue of the interface include technical and behavioural factors and both are important. In the paper concept of human-system interfaces as information channels is used for the purpose to analyse characteristics of the dynamics effects of information interfaces. As the result of analysis the adaptive dynamics...
Human-Machine-Interfaces are with no doubt one of the constitutive parts of an automation system. However, it is not till recently that they have received appropriate attention in order to improve the design of SCADA applications in industrial domain. It is because of a major concern about aspects related to maintenance, safety, achieve operator awareness, etc has been gained. Even there are in the...
In artificial intelligence, various theories on knowledge representation have gained ground. While logic descriptions, semantic nets, frames and associative networks are used for the implementation, the question which theory is best to be used as archetype for the knowledge model is controversially discussed. Regarding the use of biological principals, neural nets and psychological inspired theories...
Integrating performance measures into the process of decision making of an autonomous agent is a common method in artificial intelligence. Reinforcement learning is one possible application that can be realized with this methodology. Recent findings in artificial intelligence showed the importance of the body and the tight connection to the decision making processes. This article introduces a model...
In this paper we describe a new e-service provisioning model based on digital TV as the most familiar way to favor digital inclusion (e-inclusion) and social inclusion and to reduce the digital gap between elderly and disabled people and the information society. Different D-TV platforms are considered and several input and output interfaces for user interaction are analyzed and tested. Finally, a...
The paper overviews a vision-based technique that can be instrumental in assisting visually impaired humans in their activities. This category includes both blind people and individuals unable (e.g. due to neural disabilities) to understand semantics of the perceived visual data. Alternatively, the technique can be used as a tool for autonomous agents (e.g. mobile robots) performing in complex environments...
An electrode matrix and electronic circuit for simultaneous monitoring heart performance and respiration activity is described in the paper. The heart performance is evaluated basing on a mechanical and electrical activity. The mechanical activity is measured using bioimpedance method while the electrical one using a typical approach, i.e. one channel electrocardiogram is recorded. An electrode matrix...
The widespread use of OPC UA specification in client/server data exchange in industrial environment introduces many benefits as it allows to keep open the market of the industrial applications, due to the presence of a standard, worldwide and vendor-independent specification. On the other hand, the use of a software infrastructures (complex in the case of OPC UA) between industrial applications and...
In the article a distributed supervisory system is presented. The system consists of a set of the measurement nodes to track and supervise the most common domestic media consumption. The main goal of the system is to determine activity of the habitants. This has been achieved by means of electrical energy, water and gas consumption tracking. Several factors have been addressed in the study - such...
A new procedure for combined validation of learning models - developed for specifically uncertain data - is briefly described; it relies on a combination of resubstitution with the modified learn-and-test paradigm, called by us the queue validation. In the initial experiment the elaborated procedure was checked on doubtful (presumably distorted by creative accounting) data, related to small and medium...
This keynote paper discusses the problem of outdoor mobility of the visually impaired and reviews key assistive technologies aiding the blind in independent travel. Space perception abilities important for mobility of the visually impaired are discussed first and related definitions and basic concepts such as: cognitive mapping, wayfinding and navigation are explained. The main mobility barriers the...
Toyota has been developing industrial robots since the 1980s. In recent years, man-machine cooperative robots that assist people s skills have gradually been put into practical use. Now, Toyota is further evolving a number of robot technologies born at production sites to develop Partner Robots that work in harmony with people. Toyota is specifically considering four development areas: (1) manufacturing...
The following topics are discussed: human-system interactions; artificial intelligence; human-machine interaction; education and training; telemedicine and e-health; cyber security; and human-centered design.
As mobile devices are becoming more ubiquitous, it is now possible to enhance the security of the phone, as well as remote services requiring identity verification, by means of biometric traits such as fingerprint and speech. We refer to this as mobile biometry. The objective of this study is to increase the usability of mobile biometry for visually impaired users, using face as biometrics. We illustrate...
Previous studies of depth and distance estimation with autostereoscopic 3D displays indicate the users do not necessarily exhibit better depth perception with such displays. Yet, users claim 3D displays provide higher immersiveness. As shapes of objects are often described by their angles, it is expected that angle perception would contribute to object recognition and scene understanding. However;...
