The Marrakech Treaty (MT) is a milestone in the relationship between copyright and human rights, is the first international treaty to be established with the exclusive objective of protecting cultural rights. This article details the most relevant aspects of the Treaty, its impact on the development and implementation of Accessible Educational Resources Repositories, and describes exceptions and limitations...
In order to evaluate the recovery effect of the visible light band in the low-altitude remote sensing, the sensitivity and significance of the visual perception of the restored image are selected and optimized by the perceptual characteristics of the human visual system. Finally, the effective detail retention ability, Structure information, multi - scale similarity and visual fidelity. A kind of...
Over the years of software development, a vast amount of source code has been accumulated. Many code search tools were proposed to help programmers reuse previously-written code by performing free-text queries over a large-scale codebase. Our experience shows that the accuracy of these code search tools are often unsatisfactory. One major reason is that existing tools lack of query understanding ability...
Through the digitization of text corpora, information previously unavailable has become increasingly common. Among this information, the table of contents and index have been under-utilized for book search. This information can be represented visually, making it easier for the user to analyze the data efficiently and intuitively. By gradually narrowing in focus, from a large repository, to a few books,...
In this article we present a system capable of graphically representing the interactions between students and teachers in hierarchical online forums. By defining the âreply-to' relation between the users the system builds a graph. During forum posts mining, the system computes metrics taken from social network analysis which are then applied to the graph drawing process. This system brings...
The demand and the satisfaction of the reader are a service and creative system that is circuitous. So this paper attempts to construct a synthetic evaluation model of reader satisfaction in virtue of the relevant theory of the management psychology and the fuzzy math, and we have made a practical research and analysis on one university library with this model.
This paper presents a novel method of contour reconstruction from dexel data solving the shape anomalies for the complex geometry in virtual sculpting. Grouping and traversing processes are developed to find connectivity between dexels along every two adjacent rays. After traveling through all the rays on one slice, sub-boundaries are connected into full boundaries which are desired contours. The...
The research presented in this paper aims at developing and validating a predictive tool of individual exposure to solar Ultra-Violet (UV). UV exposure depends on ambient irradiation level and individual factors related to activity (position to the sun, clothing, duration of exposure, and other forms of sun protection). We predict exposure levels of body parts on basis of ambient irradiation levels...
Inheritance is an important mechanism when developing object-oriented programs with class-based programming languages: it enables subtyping, polymorphism, and code reuse. Inheritance is also known as a difficult feature to grasp and to use correctly because of its many purposes. We propose a model of inheritance to help understand class hierarchies of class-based object-oriented programs. We define...
In this paper, a software framework and database system for biomedical image related to Chinese human genetic resources was proposed and implemented base on web database technique and SOA architecture. Firstly, the image characterization and storage implemented well with the conceived database system. Secondly, the customized imagery retrieval methods and the metadata retrieval approach were introduced...
