Internet-enabled cameras pervade daily life, generating a huge amount of data, but most the video they generate is transmitted over wires and analyzed offline with human in loop. The ubiquity limits that can be sent to cloud, especially on wireless networks where capacity at premium. In this paper, we present Vigil, real-time distributed surveillance system leverages edge computing support tracking enterprise campuses, retail stores, across smart cities. Vigil intelligently partitions...
This article proposes a time-synchronized fault-tolerant convergence control method for n-degree-of-freedom robotic manipulators. The main challenge lies in driving the tracking errors of all joints to converge simultaneously, especially presence system faults, external disturbances, and model uncertainties. We introduce normalized sign function that guarantees property ratio persistence plays crucial role control. A observer is proposed not only adopts framework but also overcomes lumped...
Driven by a growing range of applications in the automotive, industrial, military, aerospace, computer, telecommunication, consumer electronics, and medical electronics industries, miniaturization use flex circuits continue to be prime interest manufacturers.

A time-synchronized (TS) convergence control method for robotic manipulators is proposed. Adversely to finite-time control, a notion of time-synchronization introduced based on the ratio persistence property, which can ensure that all system components converge simultaneously in finite time. Firstly, robust disturbance observer constructed be compatible with framework and precisely estimate uncertainties. Furthermore, we design (finite) controller states manipulator an equilibrium point,...
Toroidal dipole resonance can significantly reduce radiation loss of materials, potentially improving sensor sensitivity. Generally, toroidal response is suppressed by electric and magnetic dipoles in natural making it difficult to observe experimentally. However, as 2D metamaterials, metasurfaces weaken the dipole, enhancing response. Here, we propose a new graphene-integrated metasurface an ultra-sensitive chemical sensor, capable qualitative detection chlorothalonil terahertz region, down...
