Owing to the significant advantages of linear transformer driver (LTD) technology, it becomes an advanced pulsed power technology for the construct of high-voltage, high-current pulsed-power accelerators. One of the most difficulties of implementation of LT D is required triggering all the switches in the cavities synchronously with the arrival of the electromagnetic pulse propagating downstream....
Participation in social networking sites has dramatically increased in recent years. Users on social networking sites spend lots of time generating large quantities of various personal content items (eg. diaries, albums, and comments) and browsing these varieties of content everyday. However, existing social networking sites do not provide effective access control mechanisms to assure the privacy...
Private attributes of Online Social Network (OSN) users can be inferred from other information (which is usually from users' friends and group information). To address this, social networking sites allow users to hide their friend lists and group lists, so that general public cannot see them. However, if a user doesn't make his friend list public, but his friends have public friend list where we can...
Classical papers are of great help for beginners to get familiar with a new research area. However, digging them out is a difficult problem. This paper proposes Claper, a novel academic recommendation system based on two proven principles: the Principle of Download Persistence and the Principle of Citation Approaching (we prove them based on real-world datasets). The principle of download persistence...
Rough set theory has been widely applied to feature selection. In this paper, a multi-objective ant colony optimization algorithm is proposed for rough feature selection. This algorithm evaluates the constructed solutions on the basis of Pareto dominance. Moreover, it only uses the non-dominated solutions to add pheromone so as to reinforce the exploitation and adopts crowding comparison operator...
