Besides the regular biological or biomedical imaging applications, time-gated fluorescence lifetime imaging microscopy (FLIM) could be used to image living cells or rapid biochemistry reactions by its advantage of wide field and obvious parallel acquisition speed. As the basis of system detection mode, a good fitting algorithm could satisfy the lifetime precision and acquisition demand at the same...
A control software named as gated imaging lab (GIL) for 2D/3D underwater or atmospheric range-gated imaging has been introduced. First, a detailed analysis of the functional requirements of imaging system is made. Based on its operating principle and hardware components, functional modules of GIL are determined. It mainly includes zooming and focusing lens, setting gated intensified charge-coupled...
A multi-radio wireless mesh network has the potential to provide higher throughput and a variable-width spectrum allocating strategy can bring this potential into play. This paper presents an improved packing algorithm base on interference condition in the wireless communication model and the characters of wireless mesh networks. Due to the fact that interference range varies with its channel width,...
These different applications require different QoS (Quality of Service) guaranteed in wireless mesh networks, such as IP telephone, video conference, video on demand (VOD), remote education and other real-time multimedia business, e-commerce. In order to achieve the satisfactory performance in WMNs, we put forward a QoS guaranteed hybrid channel assignment strategy for a multi-Interface wireless mesh...
A new method to extract the series resistance of polycrystalline silicon (poly-Si) thin-film transistors (TFTs) is proposed. Different from conventional methods, this method is based on an analytical poly-Si TFT model and is insensitive to channel length and mobility variations. This method is demonstrated in both n- and p-type poly-Si TFTs.
A new method for extraction of series resistance is proposed for poly-Si thin-film transistors. In this method, the extraction procedure is insensitive to the variation in effective channel length and device mobility, since both quantities are included in a single extracted parameter. The method has been successfully applied to a group of poly-Si TFTs with mask channel length from 2 to 30μm. Compared...
Hydrogenation effect on reliability of n-type metal-induced laterally crystallized poly-Si TFTs is systematically evaluated by comparing device transfer and output characteristic degradation under both hot carrier (HC) and self-heating (SH) stresses. Under HC stress, hydrogenated device exhibits better stability in transfer characteristics, but worse stability in output characteristics. Under SH stress,...
