This paper reviews the literature of technology assessment published over 1977 to 2016 to identify the major research themes over the past four decades. We retrieve 5493 articles from the Web of Science database and construct the citation network among them. By applying the edge-betweenness clustering technique to the citation network and splitting the data into groups, 4 major groups with more than...
This study applies a novel approach to identify the research fronts of literature in tourism over the past decades. A research front is a coherent topic addressed by a group of researchers in recent years. It is difficult to adopt any traditional methodology to explore the research fronts of tourism literature due to the large amount of data. We retrieve tourism articles over the period 1977 to 2013...
To compete with solid state drives(SSDs), hard disk drives (HDDs) must improve their performance in capacity, speed and reliability, which requires the spacing between the magnetic disk and the magnetic transducer, used to read and write information on the disk, to decrease. which makes the gas between the slider and the disk rarefied. Such small space distance, makes contamination on the air bearing...
Intellectual property rights (IPRs) protection is strategically crucial for multinational corporations which are heavily conducting technology innovation to keep their technological superiority, competitiveness, and return of innovation investment. Developed countries are concerned that unequal protection of IPRs may result in a significant loss through unauthorized imitation in other countries while...
This paper adopts a novel approach to explore the development trajectories of automatic identification technologies by analyzing various main paths on the patent data. We retrieved the citation data on patents in automatic identification techniques from the database of USPTO (United States Patent and Trademark Office) and then built the citation network. Several main path analyses were applied on...
