Computer networks are nowadays subject to an increasing number of attacks. Intrusion Detection Systems (IDS) are designed to protect them by identifying malicious behaviours or improper uses. Since the scope is different in each case (register already-known menaces to later recognise them or model legitimate uses to trigger when a variation is detected), IDS have failed so far to respond against both...
Nowadays, interaction represents an attractive approach for deploying new forms of entertainment and art. Towards this aim, novel technologies can make possible advanced concepts of interaction, hence supporting complicated application scenarios. In this work, an interactive audiovisual installation is presented, which aims to make the participant interact with the stars in the space. Human gesture...
A novel biometric recognition system is designed in this paper, using ground reaction force (GRF) measurements of continuous gait. Original GRF signals are combined in three directions Respectively. Waveform interpolation and align ment are performed to meet th e demand of feature extraction ba sed on wavelet packet (WP) decomposition, re-sampling approach is utilized to expand valid training sets...
Rough set flow graphs proposed by Z. Pawlak are a useful tool for the knowledge representation. They can be applied to represent the knowledge of transitions between states included in multistage dynamic information systems. The knowledge represented by flow graphs is a basis for determining possibilities of appearances of states in the future using the max - min fuzzy composition. For this composition,...
EEG Systems and Brain-Computer Interfaces (BCIs) are terms that are commonly used and discussed in the field of neurological research. From a technological point of view, the components and techniques used to build technical devices for this purpose are also widely discussed. Undifferentiated use of the terms EEG Systems and BCIs in the same context provokes a discussion because they in fact refer...
This paper describes proposal for the application modified Ant Colony Optimization Algorithm in the task for recruitment and selection of employees. After analyzing the combinatorial problem involving multicriterial process of recruitment and selection model proposed non-compensating its solution using the modified ACO heuristic strategy, showing a lack of opportunities to receive appropriate the...
This paper introduces an embedded architecture and the low-level video processing algorithms developed for an intelligent node that is a part of a distributed intelligent sensory network for surveillance purposes. In this paper, details of the architecture developed for this node are given, together with the low-level video processing algorithms used, as well as the results obtained after their implementation...
This paper focuses on the design of wearable system operation modes in context of cooperation between personal healthcare systems. The patient is currently provided with telemedical solutions for home care and seamless diagnosis based on selected vital parameters. When two or more specialized systems are applied for monitoring of the same subject, the possible interference and cooperation are in question...
Disability is one of the major problems of the contemporary world. There are new technical means, methods of work and education for people with disabilities, making it possible to use a computer. The aim of this work is to allow people with upper limb dysfunction to use a computer. This aim was implemented by creating a system controlled by moving the eyeball. The solution proposed by the authors...
This article presents the tryout of increasing computer and internet security by means of complementing the authentication procedure with the gaze tracking. The eyes of the person who is being identified follow the point on the computer screen and eye movement tracking system is used to collect information about eye movements during the experiment. We based on the Yarbus experiment who showed that...
SCADA systems are nowadays exposed not only to traditional safety and availability problems, but also to new kinds of security threats. These are mainly due to the large number of new vulnerabilities and architectural weaknesses introduced by the extensive use of ICT and networking technologies into such complex systems. The analysis of the effects of these new threats is a mandatory activity to ensure...
Mechatronic transmissions are used to transfer mechanical power between the mechatronic components of a system. Often, the positions of the components are giving angles between axes that can be made difficult with conventional gears. The paper gives a method for designing the transmission based on helical gears because they provide domains for the angles between the axes which can't be obtained with...
Neural network based system is proposed as a tool supporting time series forecasting. Wavelets analysis is suggested for raw data preprocessing. The preprocessed data are fed into SOM neural networks for clustering. The system has been tested as a tool supporting stock market investment decisions and shows good prediction accuracy of the method. However effectiveness, measured by income from shares...
In an intelligent environment one important task is to observe and analyze person's daily activities. Through analyzing the corresponding time series sensor data the person's daily activity model should be build. To build such a model some problems have to be overcome: the sensor data count increase sharp with time and the distribution of the data is dynamically according the person's daily activities...
Multi-agent system (MAS) is farther development of distributed artificial intelligence. Agent technology is an advanced control method. Now the human are faced with the problem of energy sources lack and environment worsened. Wind and solar energy will be promising renewable energy in century. But randomicity and complexity of climate make windsolar hybrid power generation system difficult to be controlled...
The paper addresses the analysis of three methods for inverse kinematics of a 3-DOF medical parallel robot with R-P-S (Revolute-Prismatic-Spherical) joint structure using MATLAB/Simulink and dSpace platform. The three methods were implemented in MATLAB/Simulink and than exported to dSpace realtime development platform. A comparation between the times of these three methods has been studyed. The scope...
For modern human system interaction, traditional methods based on keyboard and mouse use do not prove sufficient. Especially when thinking about the poor and ill-qualified citizens of the Information Society, we must try to find the easiest and most comfortable method for human system interaction. The optimal method for communication processes going from man to machine is (or should be) speech communication...
This paper gives two original model-based fuzzy control solutions dedicated to the longitudinal slip control of Antilock Braking System laboratory equipment. The parallel distributed compensation leads to linear matrix inequalities which guarantee the global stability of the fuzzy control systems. Real-time experimental results validate the new fuzzy control solutions.
Patients with a tremor find it often very difficult to handle IT Systems and therefore attain very low levels of efficiency when doing so. The currently available user interfaces do not guarantee a sufficient precision when data input and selection is performed. People suffering from a intention tremor observe a significant increase in their tremor when approaching their input “destination” on the...
Character recognition is an active field of research. Applications include point of sale systems, tablet computers, personal digital assistants (PDAs), smart phones, and military applications. Recognizing Asian characters has been pursued since 1984, and difficulties exist in Japanese due to the complexity and numbers of Kanji, Hiragana, and Katakana characters. It is further complicated by differences...
