REAL: Ein ressourcenadaptierendes mobiles Navigationssystem     

Wolfgang Wahlster  J?rg Baus  Christian Kray und Antonio Krüger 《Informatik - Forschung und Entwicklung》2001,16(4):233-241

Zusammenfassung.   Die intelligente Ressourcenadaption ist eine der gro?en Herausforderungen für die n?chste Generation mobiler Navigationssysteme. Da man typischerweise mehrere Fortbewegungsarten oder Verkehrsmittel kombinieren muss, um an einen Zielort zu gelangen, muss sichergestellt werden, dass mobile, allgegenw?rtige Navigationshilfen dies über eine jeweils situationsangepasste Benutzerschnittstelle unterstützen. Der notwendige Wechsel zwischen verschiedenen Positionierungstechnologien soll für den Endbenutzer m?glichst unbemerkt bleiben. Im folgenden wird ein hybrides Personennavigationssystem vorgestellt, das die in bestimmten Fortbewegungssituationen verfügbaren Positionierungstechnologien und deren Genauigkeit optimal nutzt, um die Pr?sentation der Wegbeschreibung auf verschiedene Endger?te und Ausgabemodalit?ten sowie die kognitive Ressourcenlage des Benutzers zu adaptieren.

FC SAN与IP SAN架构在数字图书馆中的应用研究   总被引：6，自引：0，他引：6  

朱月梅  徐豁  朱玉  滑海 《图书情报工作》2006,50(9):113-116

认为针对数字图书馆海量数据存储的现状及需求，构建一个安全、高效的存储后台已成为数字图书馆建设中的重要任务，而目前较常用的DAS、NAS、SAN三种网络存储模式各具特点，且SAN架构具有集中管理和高性能存储的特点。结合具体应用实例对SAN架构中以Fibre Channel搭建的FC SAN和以iSCSI搭建的IP SAN进行综合分析，提出一种基于FC SAN与IP SAN架构的综合网络存储方案。  相似文献   

校外访问代理软件的分析与比较   总被引：12，自引：0，他引：12  

叶新明  陈光锋 《现代图书情报技术》2006,(1):83-85

校外访问是图书馆基于互联网而开展的一种新型的电子资源服务方式。校外访问能够通过代理软件来实现，其原理就是将校外访问用户的IP地址虚拟成校园网内部的私有IP地址。本文将对能够实现校外访问的三种较为典型的代理软件，即EZproxy、ISA Server（VPN）和Squid进行分析与比较，旨在对我国图书馆同行开展校外访问服务能够起到一定的抉择和指导作用。  相似文献

Does Physical Activity Enhance Learning Performance?: Learning Effectiveness of Game-based Experiential Learning for University Library Instruction     

Kosuke Kaneko  Yuriko Saito  Yukari Nohara  Eriko Kudo  Masanori Yamada 《The Journal of Academic Librarianship》2018,44(5):569-581

This paper reports research results of the proposed experiential learning using a game-based educational material. The educational material was an application running on a mobile device and was supported for learners to study university library instruction. During the experiential learning, the learners answered several quizzes provided from the educational material. The quizzes were including experiential contents such as actually to find an academic journal or to reserve a learning room. In order to evaluate learning effectiveness of the experiential learning, this research made a comparative experiment. The experimental group used the educational material and the control group used another educational material of e-learning (non-experiential) but the contents was almost same as the contents of the experiential learning. The comparative experiment took several evaluation elements such as pre-/post-test scores, delayed-test scores and learning motivation scores based on IMMS of ARCS model. The experimental results revealed that experiential learning was superior for the several elements of these metrics. This research, furthermore, analyzed learner's operation data to the educational material and learner's behavior data during the learning in the experimental group. The analyzing results showed three types of the learning behaviors and indicated that an instructor needs to adopt suitable instructional design to each type to bring superior learning effectiveness.  相似文献   

Setting the future of digital and social media marketing research: Perspectives and research propositions     

《International Journal of Information Management》2021

The use of the internet and social media have changed consumer behavior and the ways in which companies conduct their business. Social and digital marketing offers significant opportunities to organizations through lower costs, improved brand awareness and increased sales. However, significant challenges exist from negative electronic word-of-mouth as well as intrusive and irritating online brand presence. This article brings together the collective insight from several leading experts on issues relating to digital and social media marketing. The experts’ perspectives offer a detailed narrative on key aspects of this important topic as well as perspectives on more specific issues including artificial intelligence, augmented reality marketing, digital content management, mobile marketing and advertising, B2B marketing, electronic word of mouth and ethical issues therein. This research offers a significant and timely contribution to both researchers and practitioners in the form of challenges and opportunities where we highlight the limitations within the current research, outline the research gaps and develop the questions and propositions that can help advance knowledge within the domain of digital and social marketing.  相似文献
