As an efficient multi-core system structure, three-dimensional Network-on-Chips (3D NoC) opened a new filed of System-on-Chip (SoC) research. In this paper, we present an efficient routing algorithm for 3D NoC applications. This method is based on west-south-first routing algorithm and intra-layer routing has higher priority. We introduce the concept of possible deadlocked configurations and further...
A G-band rectangular beam multi-gap Extended Interaction Klystron (EIK) with unequal-length gaps is proposed. The high-frequency features indicates that the designed model has wide frequency intervals with π mode, which has a good uniformity in field distribution with the maximum (R/Q)•M2. The PIC simulation shows a stable output power of 1378 W without oscillation in 218.9 GHz, with the efficiency...
Shared control is an important approach to avoid the driver-out-of-the-loop problems brought by imperfect autonomous driving. Steer-by-wire technology allows the mechanical decoupling between the steering wheel and the road wheels. On steer-by-wire vehicles, the automation can join the control loop by correcting the driver steering input, which forms a new paradigm of shared control. The new framework,...
The diamond pillbox window for W-band TWT has been designed in this article, which can cover the 75GHz-120GHz with a ultra-bandwidth over 40GHz. By simulating and optimizing in detail, the reflection coefficient (S11) less than −20dB and the VSWR less than 1.2 was obtained in the whole transmission bandwidth with no any oscillation observed. The influence of key structural parameter on the whole bandwidth...
In this chapter, recent progress in the synthesis, crystal structures and physical properties of monomeric phthalocyanines (Pcs) is summarized and analysed. The strategies for synthesis and modification of Pcs include axial coordination of central metal ions, peripheral substitution of Pc rings and the ionization of Pcs. The crystal structures of various typical Pcs, especially the effects of different...

A real-time surveillance system for IP network cameras is presented. Motion, part-body, and whole-body detectors are efficiently combined to generate robust and fast detections, which feed multiple compressive trackers. The generated trajectories are then improved using a re-identification strategy for long term operation.
The research on Geography of Information Society concerns about the impact of information on space. The various information patterns of the spatial features emerged in the internet are important evidences that information impacts greatly on the field of space, and quantitative identification of these patterns is an important way of recognizing the depth of the effecting. Selecting 154 tourist attractions...
The research on spatial pattern and development regularity of recreational regions around metropolises is the important theoretical basis of urban planning. But in current times there are few quantitative studies on it. Selecting 1172 samples of recreational regions in Beijing, using the function of Nearest Neighbor Indicator (NNI) and the spatial analysis and geographical statistical function of...
Based on the remote sensing image interpretation data of land use of Ningjin county in 2008, using the county and township scale as the basic measuring and calculating unit, through the calculation of fractal dimension of cultivated land, garden and residential site which belong to this county and all its towns, the results can be get. The result shows that, within unitscale of county, the fractal...
Estimation of optical flow is an important topic to provide motion information for motion analysis. This paper addresses an effective confidence based optical flow algorithm. It considers the bidirectional symmetry of forward and backward flow to compute the confidence measure for each flow estimate. According to the confidence, the reliable flow estimates have greater contribution to local averages...
Seven variable block sizes are adopted for inter-frame MB (macroblock) coding in H.264. This new feature achieves significant coding gain. However, the computation complexity of the mode decision is extremely high when RD (rate distortion) algorithm is used. In this paper, we propose a fast mode decision algorithm with fast coding block size selection based on MB motion characteristic for inter frames...
