Domain-oriented web page extraction is a new and practical direction in the field of information extraction. The paper focuses on the representation of domain-oriented web page topic features, and hierarchical vector space (HVS) model is put forward. Considering the hierarchical characteristics of the web page itself, topic features of the web page are expressed more effectively by HVS model fr...

BACKGROUND Dysfunctional breathing/hyperventilation syndrome (DB/HVS) is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply and/or too rapidly (hyperventilation) or erratic breathing interspersed with breath-holding or sighing (DB). DB/HVS can result in significant patient morbidity and an array of symptoms including breathlessness, chest tightness,...

Some studies provide evidence that humans could actively exploit the alleged technological advantages of autonomous vehicles (AVs). This implies may tend to interact differently with AVs as compared human driven (HVs) knowledge are programmed be risk-averse. Hence, it is important investigate how in complex traffic situations. Here, we investigated whether participants would value interactions ...

Deletion of the terminal repeats (TR) from herpesvirus saimiri (HVS) renders it unable to produce infectious virus or generate plaques. However, a TR-deleted HVS bacterial artificial chromosome can form replication compartments. Complementation of this mutant shows that one copy of the TR, plus the right junction of the genome with the TR, is sufficient for efficient plaque formation and genera...

In typical display viewing conditions, observers are perceptible as different color temperatures at the luminance levels, illuminant, and reference white of display. In the same luminance level, adaptive neutral point(NP) of human visual system(HVS) is determined by not only illuminant’s correlated color temperature(CCT) but also display reference white. However, if luminance level is not as hi...

We propose a fast, yet simple algorithm to find the Region of Interest (ROI) from a compressed MPEG video bitstream, with partial decoding. We have used the properties of the Human Visual System (HVS), applied in the DCT domain, to extract the ROIs. Though a lot of work has been done to obtain ROIs in images based on the HVS, all these systems work in the pixel domain. However, finding the ROIs...

An adaptive watermarking algorithm is presented which exploits a biorthogonal wavelets-based human visual system (HVS) and a Fuzzy Inference System (FIS) to protect the copyright of images in learning object repositories. Specifically, the HVS relies on the linear-phase property of biorthogonal wavelet filters (symmetric wavelets) in order to efficiently extract the masking information, while t...

RATIONALE AND OBJECTIVE The set partitioning in hierarchical trees (SPIHT) wavelet image compression algorithm with the human visual system (HVS) quantization matrix was investigated using x-ray coronary angiograms. We tested whether the HVS quantization matrix for the SPIHT wavelet compression improved computer model/human observer performance in a detection task with variable signals compared...

Abstract The Action Governor (AG) is a supervisory scheme augmenting nominal control system in order to enhance the system's safety and performance. It acts as an action filter, monitoring commands generated by policy adjusting ones that might lead undesirable behavior. In this article, we present approach based on learning developing AG for autonomous vehicle (AV) decision policies improve the...
