E-commerce live streaming as an increasingly popular sales model has generated a significant amount of gross merchandise value (GMV) for e-commerce platforms. Live recommendation systems (LSRS) aim to recommend the most appropriate channels users motivate them buy products. Existing LSRS methods focus only on user's interaction behaviors channel (live domain) while ignoring and intentions product (product domain). As result, consistent purchase in cross-domain are not being fully captured,...

This paper summarizes the development of a semi-physical ground testing system designed for magnetic-only attitude determination and control (ADCS) nano-satellites. Based on dynamic sensor models, is built PC connected to on-board computer via WIFI. The software based MATLAB with scalability different algorithms, actuator models. Finally, applied evaluate pre-flight model ADCS results show that can fulfil flight requirements stabilization.

The rise in “urban diseases” like population density, traffic congestion, and environmental pollution has renewed attention to urban livability. Walkability, a critical measure of pedestrian friendliness, gained prominence transportation planning. This research delves into comprehensive analysis walking accessibility, examining both subjective objective aspects. study aims identify the influencing factors explore underlying mechanisms driving walkability within specific area. Through...

We present Real-time Gaussian SLAM (RTG-SLAM), a real-time 3D reconstruction system with an RGBD camera for large-scale environments using splatting. The features compact representation and highly efficient on-the-fly optimization scheme. force each to be either opaque or nearly transparent, the ones fitting surface dominant colors, transparent residual colors. By rendering depth in different way from color rendering, we let single well fit local region without need of multiple overlapping...

With increasing attention to sustainable development and environmental protection, more countries turn wind energy reduce their dependence on traditional fossil fuel energy. Among the new challenges with this trend is how integrate farm existing AC network effectively. The paper presents a possible measure based VSC-HVDC, namely so-called incorporated VSC-HVDC (WVSC-HVDC). In along an grid supplies passive network. firstly introduces then space vector control strategy for supplying rectifier...

The circular-hole rotating core fog nozzle has excellent atomization performance and been widely used in the realm of spray dust. As part this study, a mathematical model was developed for predicting Sauter mean diameter (SMD) nozzles type. coaction between SMD three influencing factors axial distance, water supply pressure, outlet investigated based on customized spray’s experimental platform orthogonal design method. According to comparative analysis size range, pressure are parameters...

In this paper, a combination of numerical simulation and experimental investigation is carried out. A study on the effect low-frequency acoustic waves flow field convective heat transfer in unit structure staggered exchanger presented. Air considered as background free flow, with Reynolds number 200. The range pipe pitch ratio 2.2–5, frequency sound wave 50–200 Hz, pressure level 115–135 dB. results highlighted that reattachment phenomenon downstream cylindrical surface gradually disappeared...

In the context of high usability in single-class anomaly detection models, recent academic research has become concerned about more complex multi-class detection. Although several papers have designed unified models for this task, they often overlook utility class labels, a potent tool mitigating inter-class interference. To address issue, we introduce Multi-class Implicit Neural representation Transformer Anomaly Detection (MINT-AD), which leverages fine-grained category information...

Discrete fracture models with reduced-dimensional treatment of conductive and blocking fractures are widely used to simulate fluid flow in fractured porous media. Among these, numerical methods based on interface intensively studied, where the treated as co-dimension one manifolds a bulk matrix low-dimensional governing equations. In this paper, we propose simple yet effective for modeling fitted grids interior penalty discontinuous Galerkin (IPDG) without introducing any additional degrees...

This paper describes our champion solution to the LOVEU Challenge @ CVPR'24, Track 1 (Long Video VQA). Processing long sequences of visual tokens is computationally expensive and memory-intensive, making video question-answering a challenging task. The key compress effectively, reducing memory footprint decoding latency, while preserving essential information for accurate question-answering. We adopt hierarchical mechanism named STAR Memory, proposed in Flash-VStream, that capable processing...

In order to solve the problems of Chinese named entity recognition in field apple diseases and pests, including difficulty identifying long entities polysemous words, we proposed a model based on iterative dilated convolution. Specifically, Bert pre-trained was used as embedding layer enhance semantic representation text by integrating position information. The convolutional neural network (IDCNN) extract context features output all possible sequences labels conditional random (CRF) get...

The use of soldering based on metallurgical bonding, as opposed to conventional rubber sealing, is capable achieving the firm sealing stainless-steel subway car bodies, though corrosion resistance such joints has rarely been investigated. In this study, two typical solders were selected and applied stainless steel, their properties As indicated by experimental results, types solder exhibited favorable wetting spreading plates, successfully achieved connections between sheets. comparison with...
