In recent years, mobile sensing data are widely used for analyzing human's activities, usage patterns, emotions, health conditions and social relationships. In order to understand and analyze human's behaviors, several frameworks have been proposed to collect mobile sensing data. In this paper we extend previous works and design StarLog, which is a distributed and energy-configurable framework for...
In recent years, multilayer photonic bandgap structures comprising stacks of alternating layers of positive and negative index have been proposed for a variety of applications, such as perfect imaging, filters, sensors, coatings for tailored emittance, absorptance, etc. Following a brief review of the history of negative index materials, the performance of such stacks is reviewed, with emphasis on...
A novel current-detection mechanism based on surface plasmon resonance-enhanced polar magneto-optical effect is presented in this paper. Through the introduction of surface plasmon resonance technology and combined with hybrid nano-magnetic films, the current monitoring is indirectly realized by the real-time detection of exciting magnetic field around the wire. First, surface plasmon polaritons (SPPs)...
In this paper we design and implement a home embedded surveillance system with ultra-low alert power. Traditional surveillance systems suffer from an unnecessary waste of power and the shortcomings of memory conditions in the absence of invasion. In this design we use Pyroelectric Infrared sensors (PIR) and pressure sensors as the alert group in windows and doors where an intruder must pass through...
According to the disadvantage of D-S theory and the limitation of improved combination rule, a modified combination rule based on rough set is presented. The weight of each evidence is obtained according to its influence degree on D-S combination result. Weighted averaging the evidence in the system, the Dempster combination rule is used to realize information fusion. The numerical example shows that...
