To solve the security problem of multi-media, data hiding is one of important technologies. Loss less data hiding is a special type of data hiding technologies with the characteristic of completely recovering the cover media after the embedded data are extracted. Recently, many reversible data hiding methods have been proposed for VQ-compressed images. Lu et al. proposed a VQ reversible data hiding...
An approach is proposed to discover closed frequent itemsets with a simple linear list structure called the Frequent Pattern List(FPL) in transaction database. The approach selects representation patterns from candidate itemsets to reduce combinational space of frequent patterns. By performing two operations, signature vertex conjunction and vertex counting, it simplify the process of closed itemsets...
The traditional intensity evaluation method of land use is highly influenced by man's subjective impact, thus the evaluation result is not accurate enough. In this paper, a BP artificial neural networks model was set up to evaluate the urban land intensive use. On the basis of that, Ezhou Municipal in Hubei province was taken as a case study. The results show that urban land use of Ezhou Municipal...
The stacked ground planes with vias stitching is employed to suppress the ground-bounce induced electromagnetic emission in multilayer printed circuit boards. This paper developed an analytic normal-mode analysis and used it to design the optimized positions of the vias in the board periphery. Comparison with full-wave simulation validates that the proposed systematic design procedure can easily achieve...
Anisotropic conductive paste / anisotropic conductive adhesive (ACP/ACA) type of flex-on-board (FOB) bonding method ensures good electricity between the flex electrode and organic substrate electrode for fine pitch ?0.3 mm design layout. ACP is an alternative material for connecting two circuits except anisotropic conductive film (ACF), besides, it is industry acceptable lead free environment friendly...
RFID is a rapid-developing technology for wireless identification lately. There are many related products and systems for various applications. However, most of them only deal with logistic management or business management without involving users' concerns for personalized services. Therefore, it motivates us to develop a mobile personalized RFID system with an event processing model focusing on...
In this paper, we propose two efficient schemes, named the CID-translated forwarding scheme (CTFS) and the enhanced CID-translated forwarding scheme (E-CTFS), to forward the broadcast data in the IEEE 802.16j multi-hop relay (MR) network. Motivated by the effective CID translation, CTFS and E-CTFS primarily relay the broadcast message without appending the relay MAC header. Moreover, E-CTFS classifies...
To establish a 300 mm-wafer large-scale Fab a lot of time and a large investment is needed. In order to reduce periods of Fab from construction to the actual manufacturing and make resource more efficient, we divided our Fab into 2 phase full line Fab called Twin-Phase Fab. Because we currently have 300 mm Twin-Phase Twin-Fab now, dispatching is more complicated. We develop an advanced RTD (Real-Time...
A step-up ZVS full-bridge (FB) converter with a primary-side energy recovery circuit (PERC) is proposed. The PERC means can recover the power loss due to high spike current hiding in primary inductance when the phase-shift switching activates. High ringing currents occurring at the beginning of the two resonances each half-period can then be smoothly transferred to DC bus and restrain the resonant...
Distributed spacecraft systems implement enormous new functions by augmenting multiple spacecrafts as unified. That demands the precise positioning information about each satellite nodes in the distributed spacecraft system. To achieve the position calibration, multidimensional scaling is introduced. MDS computes a 3-dimensional map of each satellite nodes from the distance information in the system...
