Pervasive Computing Location-aware Model Based on Ontology

In order to integrate heterogeneous location-aware systems into pervasive computing environment,a novel pervasive computing location-aware model based on ontology is presented.A location-aware model ontology(LMO)is constructed.The location-aware model has the capabilities of sharing knowledge,reasoning and adjusting the usage policies of services dynamically through a unified semantic location manner.At last,the work process of our proposed location-aware model is explained by an application scenario.     

基于灰色关联度的改进TOPSIS模型在水质评价中的应用

将欧几里得距离分析法、灰色关联度嵌入到TOPSIS模型中,建立基于灰色关联度的改进TOPSIS模型,提出一种新的相对贴近度改进算法,不仅能反映方案与理想解距离上的接近程度而且还考虑形状上的相似关系;同时采用组合赋权法计算评价指标的权重,克服了主、客观单独赋权的不足.将建立的改进TOPSIS模型应用到黄河下游水质综合评价中,结果表明该模型具有良好的实用性和有效性.     

初中数学课堂教学有效性之探究

随着新课程标准体系的建立,新的数学标准课程教学给中学数学教师带来了新的挑战。新课程标准为课堂教学注入全新的教学理念,数学学习的内容应当是现实的、富有挑战性的,它要求学生主动地进行观察、实验、猜测、验证、推理与交流等学习活动,而课堂教学更需要师生大胆实践、积极探索,使其课堂教学有效性得到全方位的提高。     

An Indoor Ubiquitous Computing Environment Based on Location awareness

IntroductionComputers will weave themselves into the fabric ofeveryday life until they are indistinguishable fromit in the21st century[1]. Ubiquitous computing environment ai ms toaid in this task, providing the right services or presentingthe right infor mation to the right users , at the right ti meand in the right place . That is to say ,the system must beable toidentify where ,and under what context each personis working .Location awareness significantly enhances thefunctionality of ubiqui…
