High Consistency

The purpose of this paper is to explore the writing behaviors of Internet literature in Chinese environment, aiming to understand the basic personal characters, writing motivations and behaviors of Internet writers. Through both qualitative and quantitative researches, the study found a high consistency of personal characters within Internet writers. As the writing motivations of them, the statement that “writing is just the purpose itself” is the most popular. Meanwhile, most of Internet writers like to interact with other writers or readers. With the interaction, they revise their own writing topics and styles, which proves the Internet writing behaviors are not one-way communications, but part of a social exchanging processes.

This contribution presents the results of investigations on the reliability of techniques based on the Structure from Motion approach used for 3D digitizations of build heritage. In particular, we tested the performances of different SfM technologies within an architectural survey context and we developed a procedure with the purpose of easing the work of surveyors called to restore digital representations of artifacts at different scales of complexity. The restored 3D models were compared among each other and with a gold standard acquisition. These analysis led to qualitative and quantitative evaluations and to considerations on times and skills required by all tested technologies. In this work strengths and weaknesses are highlighted and the integration of different technologies is presented, as it represents the best solution in many and recurrent multi-scalar contexts.

In this paper, we address the problem of automatically segmenting non-rigid pedestrians in still images. Since this task is well known difficult for any type of model or cue alone, a novel approach utilizing shape, puzzle and appearance cues is presented. The major contribution of this approach lies in the combination of multiple cues to refine pedestrian segmentation successively, which has two characterizations: (1) a shape guided puzzle integration scheme, which extracts pedestrians via assembling puzzles with constraint of a shape template; (2) a pedestrian refinement scheme, which is fulfilled by optimizing an automatically generated trimap that encodes both human silhouette and skeleton. Qualitative and quantitative evaluations on several public datasets verify the approach's effectiveness to various articulated bodies, human appearance and partial occlusion, and that this approach is able to segment pedestrians more accurately than methods based only on appearance or shape cue.

Finite Element Meshes

Due to the demands on mathematical models that simulate physical properties and behaviors of automotive components, different finite element meshes often partition the same component for each disparate simulation. Commercial packages that transfer mesh dependent results from one finite element analysis to initialize another typically use a variation of a specific nodal based mapping. The simplicity and ease of implementation make this mapping very attractive. In its simplest form, the mapping first assigns a node in the analyzed model the average value of the elements that share the node. A node in the unanalyzed mesh receives its value from the closest node in the analyzed mesh. Nodal based interpolants on the new element initialize elemental values. When an element in the unanalyzed mesh requires a constant value such as its thickness, the element receives the average value at the nodes that define the element. This brief paper documents some undesirable characteristics of this nodal based transfer of material properties from one mesh to another.

Among schemes for alleviating poverty, the Integrated Rural Development Programme (IRDP) is unparalleled in its size and spread. Its evaluation, therefore, has to take account of its size and the fact that it has been in operation for less than eight years. What is disturbing is that the qualitative and quantitative evaluations of the Programme are at variance. Based on action research and careful analysis, Anil Gupta and Manu Shroff ("Rural Credit: How do the Poor See It?" Vikalpa October-December 1987) argued that the plight of the poor had not changed much because the Programme did not reflect an adequate understanding of the nature of poverty. Commenting on that article, Inderjit Khanna counters their conclusion to provide figures on credit flows as well as official survey findings to show that beneficiaries have expressed satisfaction. Detailed research and analysis on both qualitative and quantitative aspects of the Programme at various levels are called for to reconcile these differences to identify the problems and devise better ways to reduce poverty

An extensive theoretical validation exercise is presented into the speed and frequency dependent solutions associated with surface piercing vessels travelling in waves. The basis of the study lies in the formulation of the Green's function satisfying the traditionally posed linearized boundary value problem of an oscillating ship with forward speed and the development/implementation of appropriate numerical schemes of study for solution. Two widely different mathematical models in formulation and numerical algorithm, denoted as methods A and B, are discussed and employed to predict hydrodynamic coefficients, wave loads and responses of a Series 60 form and an NPL monohull. Only a selection of results are shown, but great care was taken in the overall investigation to verify and validate intermediate steps within the separate calculation procedures as well as to compare final predicted values. The extensive qualitative and quantitative agreement of comparable results from methods A and B provides a measure of confidence that the presented findings are solutions to the posed seakeeping problem. The influence of speed and frequency dependence within the context of this study are discussed as well as a preliminary study into their influence in the occurrence of irregular frequencies in the numerical schemes.
