This paper introduced the extension method and established a danger evaluation matter-element model based on debris flow surveying data of Miyun county. The research indicates that it is reasonable and feasible for using extension method in danger division of valley debris flow. It can reflect each factor's influence on danger of valley debris flow. This paper used simple correlation function to determine...
One of the major subjects of study in computational biology is finding the similarity between DNA sequences. Several techniques exist that are either based on alignment between sequences or are alignment-free. This paper demonstrates two techniques that are alignment-free. The first one is based on a graphical representation of the difference between DNA sequences, while the other one is based on...
Extracting and labeling sulcal curves on the human cerebral cortex is important for many neuroscience studies, however manually annotating the sulcal curves is a time-consuming task. In this paper, we present an automatic sulcal curve extraction method by registering a set of dense landmark points representing the sulcal curves to the subject cortical surface. A Markov random field is used to model...
Insight into brain development and organization can be gained by computing correlations between structural and functional measures in parcellated cortex. Partial correlations can often reduce ambiguity in correlation data by identifying those pairs of regions whose similarity cannot be explained by the influence of other regions with which they may both interact. Consequently a graph with edges indicating...
We present a shape-space approach for analyzing genetic influences on the shapes of the sulcal folding patterns on the cortex. Sulci are represented as continuously parameterized functions in a shape space, and shape differences between sulci are obtained via geodesics between them. The resulting statistical shape analysis framework is used not only to construct populations averages, but also used...
The fatty acid compositions in muscle of Schizothorax (Racoma) kozlovi were studied for the first time on the basis of fatty acid determination of 30 individuals of the species collected from the Wujiang River, China, by gas chromatography coupled with mass spectrometry. A total of 26 fatty acids were identified in the muscle of S. (R.) kozlovi. Palmitic acid (C16:0), stearic acid (C18:0), oleic acid...
Stereoscopic image quality assessment has been widely studied in last decades; however, the research on 3D quality of experience (QoE) is proposed recently. As a part of human stereo perception, 3D QoE plays an important role to stereoscopic image quality assessment. In this paper, an objective metric is proposed based on the hypothesis that binocular vision system is sensitive to the structure of...
Diffusion-weighted images are increasingly being employed in conjunction with T2-weighted images for accurate diagnosis of cervical cancer. However, these images suffer from eddy-current related and magnetic field inhomogeneity induced distortions. This paper presents an investigation into the reverse gradient technique to correct distortions in diffusion-weighted echo-planar images of human cervix...
Dealing with large volumes of logs is like the proverbial needle in the haystack problem. Finding relevant events that might be associated with an incident, or real time analysis of operational logs is extremely difficult when the underlying data volume is huge and when no explicit misuse model exists. While domain-specific knowledge and human expertise may be useful in analysing log data, automated...
Communication between cortices mediated by deep brain structures such as the amygdala and fusiform gyrus has been suggested to explain the enhanced perception of stimuli bearing emotional content or having facial features. In this paper, we analyze the dependence structure of the relevant brain regions to assess their connectivity in response to a facial stimulus, and to discriminate it from a mock...
Cyber situation awareness is a growingly important issue as the world becomes more and more connected. Unfortunately, the amount of data produced by existing intrusion detection tools usually significantly exceeds the cognition throughput of a human analyst. In attempting to align a huge amount of information and the limited human cognitive load, we developed a systematic approach to leverage experiences...
Colorization of gray scale images is an appealing application of image processing. This work presents a technique of the gray image coloring. Here is introduced a general technique for “colorizing” grayscale images by transferring color between a source, color image and a destination or target, grayscale image. The approach presented here attempts to provide a method to help minimize the amount of...
Without a doubt there is emotion in sound. So far, however, research efforts have focused on emotion in speech and music despite many applications in emotion-sensitive sound retrieval. This paper is an attempt at automatic emotion recognition of general sounds. We selected sound clips from different areas of the daily human environment and model them using the increasingly popular dimensional approach...
The aim of this research is study the effects of mobile phone radiations on left and right sides of human brain. High frequency group of brainwave signals (beta and alpha will be compared in term of correlation and brainwaves pattern after being exposed to the radio frequency. The brainwave signals of alpha and beta frequency bands were recorded using electroencephalograph (EEG) for three states which...
This paper presents a preliminary study on the comparison between hands-free and handheld 3G mobile phone on alpha brainwave signal for thirty samples. The resting alpha brainwave activities were recorded using EEG for three stages which are before, during and after calls. The data analysis involved correlation between left and right brainwaves signals using SPSS (Statistical Package for the Social...
This research investigates and compares the effects of listening to Al-Quran and classical music on human brain wave using EEG. The EEG signal was recorded for three states, which are before, during and after listening to Al-Quran and classical music. 28 healthy participants were randomly chosen among Universiti Teknologi MARA students with age range 20 to 28 years old. During this experiment, each...
Behavioral entrainment is an important, naturally-occurring dynamic phenomenon in human interactions. In this paper, we carry out two quantitative analyses of the vocal entrainment phenomenon in the context of studying conflictual marital interactions. We investigate the role of vocal entrainment in reflecting different dimensions of couple-specific behaviors, such as withdrawal, that are commonly-used...
Novel target association approach for indoor human tracking is designed for the multistatic ultra-wideband (UWB) radar. A new concept, namely range-Doppler video sequence, is proposed to describe the slow-time evolution of human movement in range-Doppler domain. We apply the video time density function to model human movement dynamics of range-Doppler video sequences in slow time. Sliding window correlation...
Many human actions are correlated, because of compound and/or sequential actions, and similarity. Indeed, human actions are highly correlated in human annotations of 48 actions in the 4,774 videos from visint.org. We exploit such correlations to improve the detection of these 48 human actions, ranging from simple actions such as walk to complex actions such as exchange. We apply a basic pipeline of...
Interest point detectors (e.g. SIFT, SURF, and MSER) have been successfully applied to numerous applications in high level computer vision tasks such as object detection, and image classification. Despite their popularity, the perceptual relevance of these detectors has not been thoroughly studied. Here, perceptual relevance is meant to define the correlation between these point detectors and free-viewing...
