This paper presents a fast image mosaic algorithm based on the characteristic of the edge grads. Unlike some previous algorithms, which require pure horizontal camera panning, this algorithm doesn't require constraints on how the image is taken. The algorithm can determine the matching regions of the two adjacent images by finding out the feature points and can piece up images bath horizontally and vertically. Experimental results show that this algorithm is effective. 展开更多

This article involves the study of the psychic remnants commonly known as Archetypes in Sean O'Casey's play Juno and the Paycock. Archetypes are the images or patterns recurring again and again in literature through the ages. It also focuses on the minute difference between archetype and archetypal image as discussed by Jung with special reference to the characters and other images in the play beating relevance with the universal archetypes. This article also highlights the play as a connective link in the series of the different pieces of literature via the unique use of the psychic remnants. It emphasises on the different use of those remnants interwoven in the mosaic of the characters and plot of the play. 展开更多

Every year during summer, natural and human-induced forest fires threaten the environment in the largely forested areas of the Himalayan region and the local population living near these forests. Nepal, with its multitude of forests, is one of the most forest fire-prone areas in the region. This study examines the possibility of averting forest fires, minimizing their frequency and the damage they cause, through advanced mapping of forest fire prone areas using a VHSR (very-high spatial resolution) satellite image of GeoEye-1, DEM (digital elevation data) created from topographic maps and additional data layers (e.g., precipitation, settlements). The study was conducted in Kayer Khola, Chitwan district, Nepal. The classification of the satellite image has been performed using OBIA (object-based image analysis) techniques taking into account spectral, spatial and context information as well as hierarchical properties. The land cover classification result was thereafter combined with additional data in ArcGIS, where the input layers were reclassified and all classes of the input layers ranked according to their proneness to forest fires. Fire prone areas were delineated in five classes ranging from very high to very low. The study revealed that 82% of fires occur in forest areas. This case study in Kayer Khola shows that OBIA and GIS modeling techniques can be used to successfully identify forest fire-prone areas. The mapping of forest fire-prone areas will enable forest departments in countries of the Himalayan region to delineate forest fire prone areas, which can guide the forest departments set up appropriate fire-fighting infrastructure in these areas and thus help, minimize or avert forest fires. 展开更多

A novel method was proposed, which extracted video object' s track and analyzed video object' s be- havior. Firstly, this method tracked the video object based on motion history image, and obtained the co- ordinate-based track sequence and orientation-based track sequence of the video object. Then the pro- posed hidden markov model (HMM) based algorithm was used to analyze the behavior of video object with the track sequence as input. Experimental results on traffic object show that this method can achieve the statistics of a mass of traffic objects' behavior efficiently, can acquire the reasonable velocity behavior curve of traffic object, and can recognize traffic object' s various behaviors accurately. It provides a base for further research on video object behavior. 展开更多

The feasibility analysis of projects for the preservation of the historical heritage buildings is an important problem concerning the evaluation of "the total cost of intervention", which includes all the future damage costs. The total cost of intervention represents a suitable measure of the expected deterioration risk and its evolution obviously depends on the damage process which buildings are subjected to. That damage phenomena affecting masonry buildings pleased into an aggressive environment are suitably modelled by renewal processes: this happens both in the case of catastrophic events, or in the case of the so-called "natural aging", in which damage comes off gradually in time. In the hypothesis ofa Markovian renewal process (Mrp) describing the damage process, the total cost of all the future damage is evaluated taking into account both the damage aspects: damages due to catastrophic aspects and damages due to aggressive environment, supposing different maintenance and/or rehabilitation scenarios. A semi-Markov process (s-Mp) is defined to model the damage rehabilitation history of buildings in presence of seismic events, natural ageing and rehabilitation strategies. The expected rewards connected to the process are defined; they represent a significant measure of the risk. 展开更多

Based on an upwind compact difference scheme and the idea of monotonicity-preserving, a 5th order monotonicity-preserving upwind compact difference scheme (m-UCD5) is proposed. The new difference scheme not only retains the advantage of good resolution of high wave number but also avoids the Gibbs phenomenon of the original upwind compact difference scheme. Compared with the classical 5th order WENO difference scheme, the new difference scheme is simpler and small in diffusion and computation load. By employing the component-wise and characteristic-wise methods, two forms of the new difference scheme are proposed to solve the N-S/Euler equation. Through the Sod problem, the Shu-Osher problem and tbe two-dimensional Double Mach Reflection problem, numerical solutions have demonstrated this new scheme does have a good resolution of high wave number and a robust ability of capturing shock waves, leading to a conclusion that the new difference scheme may be used to simulate complex flows containing shock waves. 展开更多

Horseshoe vortex topological structure has been studied extensively in the past,traditional"saddle of separation"and new"attachment saddle point"topologies found in literature both have theoretical basis and experimental and computational evidences for support.The laminar incompressible juncture flows at low Reynolds numbers especially are observed to have new topology.Studies concerning the existence of the new topology though found in literature,the topological evolution and its dependency on various critical flow parameters require further investigation.A Particle Image Velocimetry based analysis is carried out to observe the effect of aspect ratio,?*/D and shape of the obstacle on laminar horseshoe vortex topology for small obstacles.Rise in aspect ratio evolves the topology from the traditional to new for all the cases observed.The circular cross section obstacles are found more apt to having the new topology compared to square cross sections.It is noted that the sweeping effect of the fluid above the vortex system in which horseshoe vortex is immersed plays a critical role in this evolution.Topological evolution is observed not only in the most upstream singular point region of horseshoe vortex system but also in the corner region.The corner vortex topology evolves from the traditional type to new one before the topological evolution of the most upstream singular point,resulting in a new topological pattern of the laminar juncture flows"separation-attachment combination".The study may help extend the understanding of the three-dimensional boundary layer separation phenomenon. 展开更多

This article scrutinizes three texts about Xun Zi written during the Qin-Han period: the final part of "The Questions of Yao" in the Xunzi, a rebuttal by one of Xun Zi's disciples of the idea that Xun Zi was inferior to Confucius; "Mencius and Xun Zi" by Sima Qian in his Records of the Grand Historian; and the Annotated Book of the Xunzi by Liu Xiang. We explore the images of Xun Zi as a great Confucian (大儒) that emerge from these texts, as well as their authors' motives for writing. These texts are understood within three contexts: first, the self-identification of a Confucian; second, the dispute between Confucianism and Daoism; and lastly, the distinction between the classics and the annals and biographies. Due to their different discourse environments, Xun Zi's great Confucian image project a different significance in each: in one, he is a model of action who can act in accordance with perfected morality; in another, he is a model of "private words," who can counter the philosophers of his day and become the teacher of kings; and finally, he is a model of "official learning," able to use his knowledge of the classics in practical statecraft and elucidate the kingly Way. Overall, these three texts represent three types of discourse on a great Confucian. At thesame time, they also exhibit their writers' consciousness of their times and their views of the genealogy of daotong, or transmission of the Way; hence their significance for intellectual history. 展开更多
