INTRODUCTION Bangla language is characterized by a rich sys-tem of inflections(VIBHAKTI),derivation,and compound formation(Saha et al.,2004;Dash,1994;Chakroborty,2003),which is why the NLE using Bangla(output generation)is a very challenging task.Natural Language Engineering(NLE)is the process of computer analysis of input provided in a human language(natural language)and conversion of this input into a useful form of representation.The input of an NLP system can be:written text … 相似文献

INTRODUCTION Some structures fail geometrically before thestrength failure because of lack of stability and such afailure is known as instability failure or bucklingfailure. Determination of buckling load is importantin order to ensure the stability of a structure. If thestructure under consideration is subjected to a dy-namic load then this problem comes under the pur-view of dynamic stability problems. Examples areslender offshore structures subjected to periodic ex-citations and colum… 相似文献

The law of mass-action led chemists to the belief that reactions approach equilibrium steadily. So the discovery of chemical
oscillations came as a surprise. Now chemists are very familiar with reactions that oscillate in time and/or space. Experimental
and theoretical studies of such reactions showing temporal and spatial oscillations attract the interest of many laboratories
world-wide. The Lotka-Volterra model is the simplest mathematical model which exhibits such oscillations. In this article,
we use this model to illustrate chemical oscillations with the help of a computer program. 相似文献

This study explores children's attitudes toward individuals with special needs in Greece and in the United States. A total of 196 kindergarten‐age children participated in the study. Children's attitudes were examined using the Acceptance Scale for Kindergartners‐Revised (ASK‐R) and were further explored with the use of an open‐ended interview. In addition, the Inventory of Disability Representation (IDR) was used to collect information about how individuals with special needs are represented in school and classroom environments through books, displays, materials and curriculum. The results indicated that children in Greece and the United States were accepting of individuals with special needs. Also, children attending inclusive kindergartens held more positive attitudes when compared with children attending non‐inclusive kindergartens. Results from the interviews provided further information that contributes to the understanding of children's perceptions of people with special needs and the reasons why children become more or less favourably disposed towards individuals with special needs. Finally, IDR results indicated that the classrooms in Greece had low representations of individuals with special needs compared with US classrooms, which had moderate and high representations of individuals with disabilities in the classroom and school environments. 相似文献

The emerging interface between computer technology and cognitive psychology for performance assessment in science education
is explored. Cognitive theories of learning offer promises to transform computer technology from a test administration tool
into a process assessment tool, and computer technology offers a medium for studying the cognitive processes of learning.
Interface theories and interface technologies are briefly discussed. The technology-psychology interface may be a base for
building an alternative assessment technology. Some prototype projects in this line of inquiry are presented. As in any other
novel approaches to testing, there are several questions that need to be answered in establishing the role of the technology-psychology
interface in performance assessment. 相似文献

This study examines an important aspect of the college space planning problem for an institution which has a high density development on the campus site. A model is developed which minimizes the vertical student pedestrian movements within the building. The optimal solution obtained from the model was adjusted marginally to alleviate space dispersal problems which tend to militate against departmental coordination and interaction. The resulting assignment of space was found to be better than the existing deployment of teaching department accommodation from the perspective of minimization of student pedestrian traffic and intradepartmental interaction and administration. The study is concluded by suggesting that future investigators should consider a multiobjective approach to the resolution of space allocation problems. It indicates that academic interaction should be maximized whilst costs of relocation of occupants from existing building floors should be minimized. The consideration of these goals, together with the objectives examined in this study, appear to be central to the solution of the college space allocation problem. 相似文献

There is paucity of original research that explains phenomena related to content organization and site design of educational Web sites. Educational Web sites are often used to provide Web‐based instruction, which itself is a relatively recent phenomenon for business schools, and additional research is needed in this area. Educational Web sites are designed with a different set of criteria as compared with other sites, such as those having an e‐commerce or marketing focus. More research is needed to build a theoretical foundation for feature requirements in educational Web sites. As in any new approach to teaching and learning, critical issues need to be examined before Web‐based instruction is fully integrated into teaching processes. When developing educational Web sites, features that support pedagogy should be given primary consideration. It is therefore important to identify key elements that will have maximum impact on learning. Using Q‐sort analysis (a type of Factor Analysis), this study investigated feature requirements of educational Web sites as perceived by business students. Based on the analysis of user requirements in relation to several variables that were identified from a review of literature, group characteristics emerged from students' responses. Similarities and differences between groups were investigated, and implications of these results for development of educational Web sites are presented in this study. 相似文献
