With recent advances in wireless communication technologies, the world of mobile computing is flourishing with a variety of applications. This paper presents a mobile product information retrieval system that supports collaborative work among remote users. With the development of the system, a knowledge representation framework has been adopted which accommodates semantic relationships and similarity of product data. To illustrate the system developed, a case study in information retrieval for product design is presented.
There is a demand for powerful curriculum design systems to support the representation, exchange, integration and sharing of curriculum data over the internet; to meet the requirement, this paper use ontology to describe the concepts and their relationships in a specific domain, with which the author annotate the data models, and make sure the data model has structural information as well as semantic information. In this way, data transformation in a semantic consistent way is supported and query formulation is facilitated in the process; an ontology-based description model is also proposed to give expression and organisation of curriculum information.
Currently, the conversion of Microsoft Word documents to XML (EXtensible Markup Language) is notably unstable and inconsistent. The main objective of this paper is to research a method to convert Microsoft Word documents to XML without any loss of information during the conversion process. This paper also discusses the associated difficulties when converting Word documents to XCRI (Exchange of Course Related Information) and demonstrates the effectiveness of the output for the research project; finally, as an outcome of this research, the method and system developed to convert course information from a Microsoft Word template to an XCRI can be employed by other institutions.
A new automatic calibration system for electronic scale with image identification is developed. The system is composed with mechanical part, pneumatic components, PLC, USB camera and computer. Labview is the developing platform with user interface, PLC is controlled by Labview via OPC configuration to load or unload the standard weights, image machine vision technology is used to automatic recognize the LED char displayed on electronic scale.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
