Using AFM as a nanomanipulation tool has been discussed for more than a decade. However, its lack of real-time visual feedback during manipulation has hindered its wide application. Fortunately, this problem has been overcome by our recently developed augmented reality system. Not only can this new system provide real-time force feedback but real-time(More)
Assembly of nano-structures involves manipulation of nanoparticles, nano-rods, nanowires and nanotubes. Modelling the behavior of a nano-rod or a nanotube pushed by an AFM tip is much more complex than that of a nano-particle because in the case of the nano-particle usually only translation occurs while for the nano-rod and nanotube both translational and(More)
— Previous studies on nanomanipulation using Atomic Force Microscope (AFM) go through the scan-design-manipulation-scan cycle, in which an operator does not have any real-time visual feedback during manipulation. In this paper, a simple model of tip-substrate-object interactive forces has been presented for the qualitative and quantitative analysis. Based(More)
This paper concentrates on transparency and synchronization of supermedia in Internet based teleoperation. Supermedia is used to describe the collection of all the feedback streams in teleoperations, such as haptic, video, audio, temperature and others. Transparency and synchronization are introduced and analyzed from the event-based control perspective.(More)
BACKGROUND The brown marmorated stink bug (BMSB) is an exotic insect pest that was first recognized in the United States in 2001. As of today, it has been found in more than 42 states. BMSB has a very broad host plant range and damage to crops in mid-Atlantic States has reached a critical level. A reliable and accurate tool for infestation detection and(More)
360 degree surround view system monitoring (SVM) is a very convenient system to help drivers drive through narrow spaces blind-spot-free by looking at surround of a vehicle from top view. Nevertheless, it cannot solve the problem of parking. Even with help of 360 degree SVM system, unexperienced drivers still cannot do parking easily. In this paper, we(More)
Selective oxidation of alcohol in water using molecular oxygen as the terminal oxidant is mediated by rhodium porphyrin complexes. Addition of methanol to an aqueous solution of (TSPP)Rh(III) resulted in observation of the key intermediate porphyrin rhodium(III) methoxide species. The activation parameters for betaC-H elimination of Rh-alkoxide were(More)
In this paper, we consider a smart grid incorporating numerous devices. In order to manage the energy distribution, we propose an algorithm that employs the group bargaining concept of game theory to efficiently allocate electricity resources among these devices. First, we divide the devices into non-overlapping groups, and allow devices to bargain both(More)
