Pedestrian detection is widely used in real-time surveillance, urban traffic, and other fields. As a crucial direction pedestrian detection, dense still faces many unresolved challenges. Existing methods suffer from low accuracy, high miss rates, large model parameters, poor robustness. In this paper, to address these issues, we propose lightweight with finer-grained feature information interaction called MSCD-YOLO, which can achieve performance robustness only small number of parameters....

With the development of artificial intelligence and human-computer interaction technology, gesture has been widely used in intelligent vehicles, interaction, virtual reality, other fields as an important way communication people's daily life. However, there are few review studies that comprehensively evaluate summarize recognition recent years. To address this situation, paper classifies summarizes currently methods. Firstly, current status research on static gestures is investigated,...

The present study aimed to provide a deep insight of short-range and medium-range structural order for CaO–SiO2–TiO2–B2O3 glasses. From various prospects, four techniques, FTIR, Raman, XPS NMR, were simultaneously employed only the direct evidences indicated from spectra used analysis. FTIR Raman proved that main silicon-related units Q0(Si), Q1(Si), Q2(Si) Q3(Si) results fittings revealed B2O3 addition resulted in an increase Q1(Si) at cost Q0(Si) Q2(Si), thus inducing increasing Degree...

With the government’s increasing support for virtual reality (VR)/augmented (AR) industry, it has developed rapidly in recent years. Gesture recognition, as an important human-computer interaction method VR/AR technology, is widely used field of reality. The current static gesture recognition technology several shortcomings, such low accuracy and speed. A algorithm based on improved YOLOv5s proposed to address these issues. content-aware re-assembly features (CARAFE) replace nearest neighbor...

The present paper investigated how the SiO2 and B2O3 additions influenced crystallization behaviors of Ti-bearing blast furnace (Ti-BF) slags with a purpose recycling titanium. Ti-BF were co-modified by different contents. Isothermal experiments carried out using Single Hot Thermocouple Technique (SHTT) to in-situ determine crystal formation, accordingly Time Temperature Transformation (TTT) curves established. results showed that small amount addition can efficiently promote transformation...

Preparation of bagasse carbon-red mud (BCRM), a low-cost adsorption material used in wastewater treatment, from red and has been studied. Effects most important conditions preparation process on the capability BCRM were investigated. The optimal parameters for obtained. had high surface area good mesoporous structure exhibited an excellent capacity. could be regenerated via simple calcination at 573 K air 1 h. was effective, economic, regenerable organic contaminants wastewater.

The role of fluorine in the CaO–SiO2–MgO–Al2O3–FetO steelmaking slags was investigated through analyzing viscous flow and crystallization behaviors slags. It found that viscosity decreased with increasing CaF2 content, which resulted from decrease degree polymerization (DOP) structures, as proved by O1s X-ray photoelectron spectroscopy (XPS) magic angular spinning nuclear magnetic resonance (MAS-NMR) analysis. continuous cooling transformation (CCT) diagrams primary crystals were also...

Maneuvering target tracking technology is widely used in both military and civilian fields.Kalman filtering technique the key for maneuvering tracking.However, due to uncertainty of environment diversity sensors, defects traditional Kalman filter are revealed.To solve these problems, a variety new filters have been proposed.In this paper, we sum up application different various environments, including adaptive filter, extended filter(EKF), unscented filter(UKF), analyze problems improvement...

An analytical solution to a composite annular fin made of substrate metallic and coating layer has been carried out. Useful expressions for calculating temperature distribution efficiency have derived. Comparing the results those numerical calculation, premise is also explored. Theoretical analyzing show that coated decreases with an increase thickness if thermal conductivity much less than fin. Whereas, reverse influence on appears beyond above range.

Multi-modal medical image fusion technology is playing an increasingly important role in many clinical applications. In this paper, a fast and effective multi-modal method spatial domain proposed. our method, moving frame based decomposition framework adopted to decompose source images texture components approximation components. addition, novel weight map refined strategy on properties guide filtering proposed, the final applied fuse Experimental results demonstrate that proposed can...

Current load balancing method for large scale spatial data network service can't dynamically adjust the of servers according to characteristics data. We propose a content-based dynamic method, which can group geographical position relativity and accessing heat improve Cache utilization on server.

Recently, edge-preserving filters have achieved great success in infrared (IR) and visible (VI) image fusion field. However, most are complex. In this paper, with the side window filtering technology by which can improve their capabilities, we propose a general perceptual IR VI framework simple linear filter. Firstly, source images decomposed into edge feature components, hybrid components base using filter its version. Then, these combined max-absolute rule improved rule. Finally, fused is...

In this paper, we discuss the disadvantage of Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. LEACH··Cluster Head (CH)··is selected randomly without any parameter, such as node energy, distance. There exists a probability that energy consumption is unbalanced in WSN, which causes shortening its lifetime. proposed new LEACH-based protocol, Dynamic Cluster LEACH (DCL). Firstly, all nodes are grouped based on location, and CH elected every group, ensures CHs even distribution network...

Available parking spaces prediction is an important AI technology in the guidance system (PGS). The current technologies based on time series and neural networks can achieve quite high accuracy short-term prediction. However, with increase of steps or time-span, dramatically reduced, lose most information process. In this paper, we propose a method, named FLOPS, that keep characteristics data change long time-span. This method uses idea fuzzy granulation (FIG) to obtain feature sets. Then...

Since the policy of green credit was carried on in July 2007, commercial banks have been supporting project energy saving measures increasingly day by day. However, size loan for highly energy-consuming companies is not cut enormously, but raised continuously. This paper discussing cause increasing method mathematical analysis from perspective risk expectation. The main reason this phenomenon limitation wealth threshold and threshold, which are principal factors to judgment investment...
