In this proposed integrated Intelligent Transport System, GPS enabled smart phones, and video cameras are used as traffic sensors, while Twitter is used as verifier. They are attractive because they are non intrusive, and consequently more practical and cheaper to implement. Our novel Virtual Detection Zone (VDZ) method has been able to map match by using pre-determined check points. VDZ speed ...

This paper describes a method for automatic contour detection in long-axis cardiac MRI using an adaptive virtual exploring robot. The robot is a simulated trained virtual autonomous tri-cycle that is initially positioned in a binary representation of the left ventricle (LV) and finds the contours during navigation through the ventricle. The method incorporates global and local prior shape knowl...

Haptics is an increasingly common modality in human-computer interfacing. The focus of this paper is the problem arising from the difference between the high sampling rate requirements of haptic interfaces and the significantly lower update rates for physical models simulated in virtual environments. This is a critical problem, especially for applications involving haptic manipulation of deform...

In the ubiquitous environment, users can choose one of the devices according to their necessity and situation. Because it is very cumbersome to switch I/O device manually, middleware is made to do this work. However, seamless switching is not possible for environments in which middleware is not installed or application programs which do not run on middleware. We could resolve this problem by si...

Virtual reconstruction of large landscapes from satellite imagery can be a time-consuming task due to the number of objects that must be extracted. Poor image resolution and noise hinder automatic detection processes and thus must be corrected by the user. This paper describes an application that allows the user to guide the automatic detection of trees from satellite imagery and spatial vegeta...

With the rapid development of Internet, the network topology structure becomes more and more complex, so that the monitoring of network attack has become quite difficult. The traditional passive defence strategy has been unable to meet the demand of network information security. How to effectively detect and prevent the network intrusion have become an important matter in the field of computer ...

The paper presents a concept drift detection method for unsupervised learning which takes into consideration the prior knowledge to select the most appropriate classification model. The prior knowledge carries information about the data distribution patterns that reflect different concepts, which may occur in the data stream. The presented method serves as a temporary solution for a classificat...

We propose an efficient method for the detection of Line of Sight LOS and Multipath MP signals in global navigation satellite systems GNSSs which is based on the use of virtual MP mitigation VMM technique. By using the proposed method, the MP signals’ delay and coefficient amplitudes can be efficiently estimated. According to the computer simulation results, it is obvious that our proposed meth...

An intrusion detection system framework using mobile agents is a layered framework mechanism designed to support heterogeneous network environments to identify intruders at its best. Traditional computer misuse detection techniques can identify known attacks efficiently, but perform very poorly in other cases. Anomaly detection has the potential to detect unknown attacks; however, it is a very ...

One of the most important aspects in interactive virtual environment applications is maintaining interactive frame rates while providing realistic and believable experience. Due to this fact, collision detection for interactive virtual environment applications acts as an important part of the system. However, due to its computationally intensive nature, collision detection can become a bottlene...
