Characterizing navigation maps for web applications with the NMM approach

This paper presents the Navigation Maps Modeling approach (NMM), which provides platform independent models for characterizing navigation maps of web applications. The NMM approach is conceived to obtain a trade off between high and low-level design notations. As high-level design notations, NMM models permit architectural details that may hinder the overall understanding of the web application to be left out. As low-level design notations, NMM models can easily be transformed into detailed architectural designs, which are very valuable at coding and maintenance stages.

A new formulation for web crippling strength of cold-formed steel sheeting using genetic programming

This study presents Genetic programming (GP) as a new tool for the formulation of web crippling strength of cold-formed steel decks for various loading cases. There is no well established analytical solution of the problem due to complex plastic behaviour. The objective of this study is to provide an alternative robust formulation to related design codes and to verify the robustness of GP for the formulation of such structural engineering problems. The training and testing patterns of the proposed GP formulation are based on well established experimental results from the literature. The GP based formulation results are compared with experimental results and current design codes and found to be more accurate.     

The 2006 summary of scientific productivity of chemical engineers in Taiwan

In this report, the scientific productivity of Year 2006 of chemical engineering professionals in Taiwan was analyzed carefully with information retrieved from the database of the ISI Web of Science. The distributions of number of authors with x publication versus the number of publication x follows a general power-law trend, which coincidently comply with the Pareto distribution. The power-law indices found ranges from −1.64 to −2.22, which is consistent with values reported in the literature investigated for periods of 1907–1916 and 1969–2004.     

Putting Web Services in Context

When considering the full range of Web service-related activities, it becomes clear that dealing with context is a major challenge, requiring greater expressiveness, reasoning capabilities, and architectural components than are provided by the current widely accepted building blocks of the Web services stack. This paper presents an informal overview of concepts, requirements and challenges for handling contextual knowledge in connection with Web services, and briefly discusses several interesting projects in this area of research.

基于COM＋技术的Web服务封装研究

早期的信息管理系统都是用于实现企业特定的业务功能而建立的,包括对企业生产、供应、销售以及客户服务等的控制和管理。企业按照职能部门建立了各种企业信息系统,这些信息管理系统被其所在部门所使用,并在实际的工作生产中发挥了巨大作用。该文从整体考虑各个企业信息管理系统,并根据具体业务的需求对这些系统进行统一编排,通过一个合适的集成平台把现有企业信息管理系统进行有机的整合起来,使各＂信息孤岛＂联系起来。     

ROSA:资源敏感的高性能Web容器体系结构

现有的Web容器多采用线程池体系结构,而Web容器所支撑的动态Web组件在执行过程中可能需要获取多种共享资源,由共享资源并发量限制导致的线程阻塞可能会严重影响性能。提出了一种资源敏感的Web容器体系结构ROSA(resource-oriented staged architecture)。当某些共享资源达到饱和时,若Web容器接到对需要这些资源的Web组件的请求,ROSA会暂缓为这些请求提供服务以减少线程阻塞。基于排队Petri网,建立了ROSA结构和线程池结构的性能模型,通过模型仿真和负载实验验证了ROSA体系结构的性能优势。
