During the last years, the need for security-oriented surveillance systems has grown higher and higher. Nowadays many public environments, such as airports, train stations, etc. are monitored by some sort of video-surveillance system in order to detect or prevent security issues. The involved technology ranges from the use of plain closed-circuit cameras (CCTV) to sophisticated computer-based video...
There is a need for more reliable, non-invasive and alternative measurement sites for the monitoring of arterial blood oxygen saturation in critically ill newborns at times of peripheral compromise. The anterior fontanelle, a unique anatomical feature of the newborn, has been presented as an alternative site for the estimation of oxygen saturation. A multi-wavelength non-invasive optoelectronic sensor...
The study of fatigue is an important tool for diagnostics of disease, sports, ergonomics and robotics areas. This work deals with the analysis of sEMG most important fatigue muscle indicators with use of signal processing in isometric and isotonic tasks with the propose of standardizing fatigue protocol to select the data acquisition and processing with diagnostic proposes. As a result, the slope...
To help separate out the contributions of the somatosensory and vestibular systems to postural and sway control, short (1, 4 and 16mm) anterior translations of lengths less than the normal sway path length were made of a platform upon which blindfolded young adult test subjects (n=12) stood or sat. Acceleration detection thresholds from these short moves were compared in standing vs seated conditions...
The paper presents a novel computationally simple, easy-to-interpret compressed EEG display for multichannel intracranial EEG recordings. The compressed display is based on the level of sharp activity (relative sharpness index (RSI)) in the EEG, which profoundly increases during paroxysmal activities. RSI is graphically presented as a color-intensity plot that allows compressing several hours of EEG...
This paper proposes a conceptual hybrid cognitive architecture for cognitive robots to learn behaviors from demonstrations in robotic aid situations. Unlike the current cognitive architectures, this architecture puts concentration on the requirements of the safety, the interaction, and the non-centralized processing in robotic aid situations. Imitation learning technologies for cognitive robots have...
We developed an active virus filter (AVF) that was able to virus enrichment for single virus manipulation by using the insulator based dielectrophoresis (iDEP). The design of 3D constricted flow channel enabled the microfluidic chip to produce iDEP force. We utilized maskless photolithography to achieve the precise 3D gray-scale exposure for constricted flow channel. When we applied sinusoidal wave...
In the recent years the huge demand for miniaturized, highly functional and also more and more reliable electronic equipment is observed. The development of electronic industry strongly depends not only on the scale of electronic components miniaturization but also depends on miniaturization and kind of printed circuit boards (PCBs). Nowadays, the flexible substrates plays more and more important...
An important characteristic of many modern systems is the availability of large amounts of event data, collected through various sensors. Certain events occur very rarely among these, but may be critical to a successfully functioning system. Examples of these include faulty products, credit card frauds, among others. In this paper, we propose a framework for solving this problem, of detecting rare...
The IEEE International Workshop on the Future of Software Engineering for/in the Cloud (FoSEC 2011)aims to bridge the gap between software engineering and cloud computing by specifically addressing the software engineering challenges for software engineering for and in the cloud.
In wireless sensor network, nodes localization is the basis to communicate effectively, and it is the key technology to improve the nodes location accuracy. This paper analyzes the conventional algorithms in positioning nodes coordinate (maximum likelihood estimation, weighted least squares, kalman filter algorithm), and this paper proposes an improved algorithm for nodes localization in wireless...
Wormhole attack is a severe security threat to wireless sensor networks, and it is commonly considered challenging to detect and prevent because of its independence of MAC protocols and immunity to cryptology techniques. Nearly all the existing defenses have impractical requirements on the network, such as directional antenna, specialized GPS unit, or even tight time synchronization, which means previous...
Over the last decade, research on dependable computing has undergone a shift from reactive towards proactive methods: In classical fault tolerance a system reacts to errors or component failures in order to prevent them from turning into system failures, and maintenance follows fixed, time-based plans. However, due to an ever increasing system complexity, use of commercial-off-the-shelf components,...
