Data intensive analysis is the major challenge in smart cities because of the ubiquitous deployment of various kinds of sensors. The natural characteristic of geodistribution requires a new computing paradigm to offer location-awareness and latency-sensitive monitoring and intelligent control. Fog Computing that extends the computing to the edge of network, fits this need. In this paper, we introduce...
The purpose of the study was to investigate the effect of polling technologies integrating with strategies on students' academic performance and related brainwave signals. The participants were 34 students who registered in the educational research methodology course in a national university in Taiwan. The pre-class quiz, in-class quiz, brainwave of attention levels, open-ended questionnaires, and...
Network structure has been used to describe many systems in the real world. Nodes, which represent the units, and edges, which represent the connection of the units constitute the network structure. The monitoring of the Peer-to-Peer (P2P) networks can also be described by the general network model. In this paper, we provide an algorithm to divide network based on the social network analysis. By calculating...
In order to monitor curing process of epoxy resin in real time, the system for cure monitoring is established based on Fiber Bragg Grating. First, a bare FBG, a FBG packaged with quartz capillary and an accurate resistance thermometer are closely stacked into a special mould. Then the mould is filled with mixture of epoxy resin and curing agent. Finally they are heated and cured together in the temperature-controlled...
An energy-efficient data collection protocol for wireless sensor network based on tree (EEDCP-TB) is proposed in this paper. EEDCP-TB constructs data collection tree through the method of flooding avoidance and use the cascading timing scheme to allocate aggregation time in order to save node's energy; further more, this protocol introduce the node energy state parameter to meet energy balance to...
Remote desktop access is commonly used to remotely access a host in enterprise networks; however it also brings in security problems in supervision and auditing. In this paper, a novel proxy-based security audit system is designed and implemented in order to ensure security supervising and auditing remote desktop access. Our system effectively monitors all the accessing sessions of RDP, VNC, and X-window,...
