This paper proposes an implementation to achieve a regenerative braking control for a dual-PMSM drive system. By using the proposed maximum efficiency searching algorithm, maximum power recovery from the braking control can be obtained. A digital signal processor, TMS 320F 2808, is used to execute all of the control algorithms, including dual-motor driving control, dual-motor regenerative braking...
Silver nanoclusters (AgNCs) are an emerging set of fluorescent materials that are advantageous over semiconductor quantum dots and organic fluorophores. Herein, fluorescent AgNCs were used as potential probes for selective recognition of DNA (CGG) trinucleotide repeat that is more related to diseases. In comparison with (CCG), (CAG), and (CTG) trinucleotide repeats, (CGG) repeat is much more efficient...
Pen tilt is an additional input from digital pens, which indicates the posture information of holding a pen. In this study we couple tilt input with user interactions and explore its potential of improving user interactions. We first investigate human ability of users' controlling pen tilt in pen-based interactions. Based on the understanding of human ability of controlling this input modality we...
A wireless DALI controlled electronic ballast for ultraviolet lamp (UVL) with high-sterilization quality and energy-saving control is proposed in this paper. Up to a maximum of 64 UVLs can be simultaneously controlled through the digitally addressable lighting interface (DALI) by the devised system to provide large-scale sterilization applications. The proposed configuration consists of a digitally-controlled...
We study optimal transmission strategies in multi-channel cognitive radio networks where one secondary user (SU) opportunistically accesses multiple orthogonal channels that are owned and utilized by primary users (PU). In dynamic spectrum access networks, the protection of PU's is vital, since no PU would accommodate SU access to its own detriment. Therefore the objective of the problem we study...
Recently compressive sensor developed as an imager for capturing images effectively has been studied extensively. In this paper, we design a new imager to reconstruct high resolution image from a low resolution blurred image obtained by the intended movable random exposure. This imager grabs an image by moving a camera with a randomly fluttering shutter along a certain motion route. By analyzing this...
In traditional image encryption system, decryption is extremely sensitive to packet loss. However, in wireless networks, packet loss is inevitable. Compressed sensing (CS) theory shows that sparse signal can be recovered from few incomplete measurements of it. Strong randomness of measurement matrix and irrelevance among the elements of the measurement vector imply that measurement process can be...
We investigate the following question - how should secondary users coordinate with each other to determine which channels to sense and potentially access in a cognitive radio network? If users may have a potentially different valuation of each channel and don't know of each other's valuations, then it is unclear whether there may be some benefit to explicitly exchanging this information, albeit at...
Accelerated high level phase contrast theory is established. Global design adaptive concept, integrated principle, system strategy, spatiotemporal characteristics simulation and evaluation is studied. Accelerated system integrated technique, especially on optical design and modeling, is achieved.
