Recent advancements in 2D diffusion models allow appearance generation on untextured raw meshes. These methods create RGB textures by distilling a model, which often contains unwanted baked-in shading effects and results unrealistic rendering the downstream applications. Generating Physically Based Rendering (PBR) materials instead of just would be promising solution. However, directly PBR material parameters from still suffers incorrect decomposition, such as albedo. We introduce DreamMat ,...
Deterministic methods in indoor-localization systems based on the received signal strength (RSS) almost utilize average value of RSS, such as k- nearest neighbor (KNN) algorithm. However, distribution RSS is not always normal Gaussian real complex indoor environment so may represent location well. To solve this problem, we present a novel algorithm, named probabilistic KNN (pKNN) The algorithm uses probability Radio-map weighting to calculate Euclidean distance, and it filters whose less...
The modernization of GPS and the potential deployment GALILEO COMPASS Global Navigation satellite system (GNSS) are fostered through increasing demands for navigation location services. Some innovations realized to attain better performances over legacy GNSS. adoption secondary short synchronization codes, including Neuman Hoffman code, CS code OC is one among these innovations, which play important role on spectral separation, bit synchronization, narrowband interference protection. In this...
Autism spectrum disorder (ASD) is a common neurodevelopmental and early diagnosis crucial for effective treatment. Stable biomarkers are essential understanding the underlying causes of improving diagnostic accuracy. Electroencephalography (EEG) signals have proven to be reliable diagnosing ASD. Extracting stable connectivity patterns from EEG helps ensure robustness in ASD systems. In this study, we propose hybrid graph convolutional network framework called Rest-HGCN, which utilizes...
This paper introduces the principal of digital matched filters (DMFs), and based on Field Programmable Gate Array (FPGA), we make an analysis optimization DMFs which used in quick acquisition Pseudo-Noise (PN)-code for Global Position System (GPS). A structure as "Random Access Memory (RAM)-based shift register + folded" DMF is given this paper. Compared with traditional folded DMF, utilizes rich resources On-chip RAM FPGA chip to decrease consumption Logic Elements (LEs) chip. With...
The remarkable generative capabilities of diffusion models have motivated extensive research in both image and video editing. Compared to editing which faces additional challenges the time dimension, has witnessed development more diverse, high-quality approaches capable software like Photoshop. In light this gap, we introduce a novel generic solution that extends applicability tools videos by propagating edits from single frame entire using pre-trained image-to-video model. Our method,...
Since the location services becomes more and important in people's life, navigation methods for all kinds of objects, such as objects high-dynamic movement or strong interference environment, need to be researched. Because high-speed spinning is a special condition high-dynamic, it necessary research method this kind objects. For object without spinning, will have good tracking performance by using high-order loop Kalman filter. But object, because Doppler changes very fast, can't tracked...
The binary phase shift keying (BPSK) modulation method is generally utilized for the traditional navigation satellite systems; however, new generation of GNSS, such as modernized GPS, European Galileo, Chinese Compass, etc., will apply offset carrier (BOC) technique, which can efficiently split spectrums signals using same frequency so to reduce interferences among different systems. But autocorrelation function BOC modulated has drawback multimodality, it’s very hard synchronize right peak...
The new generation of global navigation satellite systems will apply binary offset carrier (BOC) modulation technique, which can efficiently split the spectrums signals using same frequency so as to reduce interferences among different systems. But autocorrelation function BOC modulated has drawback multimodality, it’s very hard synchronize right peak when acquiring and tracking signals, especially under low SNR circumstances, decrease positioning accuracy even lead wrong results.

TD-SCDMA, which has been widely used in China, provides better experience for mobile users than GSM did. However, weak coverage remains one of the most important problems current network as it to be GSM. One way address problem is through optimization. Traditional approaches optimization exhaustively search all possible schemes optimal solution, computationally prohibitive. It almost impossible implement such a complex solution real networks. A more efficient urgent need. The main...
