Nowadays, with rapid development of technology, Internet, mobile Internet, Internet of things and sensor network, cyberspace has expanded to a ubiquitous space of human beings, machines and Internet of things. The location of people is one of the most important feature in the Internet of things (IOTs). Therefore, we focus on identifying individuals behaviors based on their GPS trajectories to support...
With the development of wireless communications and embedded systems technologies, many smartphones are equipped with a multitude of sensors such as GPS and powerful computational, storage and communication capabilities. By these smartphones, location-based services provide the potentialto understand people's mobility pattern at an unprecedented level. How to discover people's personal mobility patterns...
In this paper we present a study on music mood classification by using only lyrics information. Specially considering the Chinese songs, the Chinese word-segmentation has caused intolerable errors and inadequate use of lyrics information. Our work proposes to use bag-of-character features instead of bag-of-word features to avoid the word segmentation error, which makes the classification more inaccurate...
The problem of collision-free path planning for six joints manipulator used for nuclear reactor repairing was considered, a new approach based on the decomposition of configuration space was presented in this paper. Since the collision with the environment occurs mainly on the three joints near the proximal joints of manipulator, the six dimensional configuration space was decomposed into two three...
In this paper we discuss the limit cycle property of a family of Brain-state-in-a-Box (BSB) models with delay. The dynamics of the model is addressed using analysis method. For the network with arbitrary weight matrix, the conditions for the existence of cycle of length 2 are presented. The advantage of the method is the ability to be predicted limit cycles in updating initial three steps. At last,...
In production process, a cutter management system should provide accurate, timely, and optimal information of cutters and their components. However, there are few cutter management and consultation systems based on B/S (Browser/Server) structure. In the paper, a cutter database management system is developed based on B/S architecture. The cutter database management system is mainly consisted of user...
