The intelligent warehouse is a modern logistics management system that uses technologies like the Internet of Things, robots, and artificial intelligence to realize automated optimize warehousing operations. multi-robot (MRS) an important carrier for implementing warehouse, which completes various tasks in through cooperation coordination between robots. As extension reinforcement learning kind swarm intelligence, MARL (multi-agent learning) can effectively create systems warehouses....

Globally, the majority of kindergarten-aged children face obesity issues and insufficient physical activity (PA) engagement. Regular PA participation can provide various health benefits, including reduction, for children. However, limited studies have investigated factors influencing children's engagement from perspective their teachers. This qualitative study aimed to identify that could help promote among teachers' perspectives, facilitators, barriers, recommendations. Fifteen kindergarten...

Ghrelin is an endogenous ligand of growth hormone (GH) secretagogue receptor (GHSR) and has a number biological effects, including heart protection. The present study aimed to reveal the positive effect ghrelin on myocardium with hypoxia/reoxygenation (H/R) treatment involved molecular mechanisms. Successful construction lentiviral expression vector (ghrelin‑pLVX‑Puro) was confirmed by colony polymerase chain reaction (PCR) verification. Primary rat cardiac myocytes were isolated identified...

Abstract:

This paper analyzes the vertical ground movement during large‐scale pipe roof installation and artificial freezing of Gongbei tunnel Hong Kong‐Zhuhai‐Macau bridge project. The transverse settlement is analyzed. loss volume ratio trough width coefficient jacking are estimated based on field measurement settlement. interaction pipes multiple investigated. effect frost heave control by pregrouting, limiting frozen soil thickness, combination two methods evaluated. analysis shows that 37 pieces...

Reliability is an essential measure of how closely observed scores represent latent (reflecting constructs), assuming some variable measurement model. We present a general theoretical framework reliability, placing emphasis on measuring association between and scores. This was inspired by McDonald's (2011) regression framework, which highlighted the coefficient determination as reliability. extend beyond coefficients introduce four desiderata for reliability measures (estimability,...

With the rapid development of city, it is necessary to obtain geological information within 500 meters. Electrical prospecting not only low cost and simple operation, but also solves problem insufficient drilling density in a survey. However, due dense urban buildings strong electromagnetic interference, difficult for traditional electrical instruments effective data. An anti-interference method instrument designed. In application test Tongzhou core area Beijing, resistivity sounding data...

With the development of smart wind turbines, more comprehensive data and information for reliability assessment turbines are provided. The can be carried out by statistically analyzing failure outage time farm units, using simulation mathematical methods. However, large-scale offshore farms, there is often problem a lack data. Moreover, compared to farms operating in complex environments, harsh conditions uncertain parameters, coupling relationships among various which improve energy farms....

The unascertained clustering is a new method, which combines theory and to construct the measure, uses measure as set membership indicate relation between samples with different classes. It overcomes disadvantage of means algorithm, that sample definitely belongs class, made greater progress than -means clustering. There are complex non-linear relationship coal industry competitiveness various factors. article established evaluation influencing factors system international competitiveness. 6...

Fuel transport is an indispensable task for nuclear power plants. For pressurized water reactors (PWR) and boiling (BWR), many research projects have been completed designing testing the casks fresh fuel as well spent [1–3]. To ensure safety of during transportation, aspects should be analyzed examined with inside, such heat transfer temperature calculation, radiation protection, nonproliferation issues, etc. The cask discussed in this paper especially new spherical elements, which designed...

Occupancy models have been popular in modeling imperfect detection ecological surveys where the occupancy rate of a species is most interest. In this paper, we incorporate into likelihood and propose an empirical (EL) estimation approach associated with EL ratio confidence interval. We show theoretically that maximum estimator coincides statistic asymptotically follows chi-square distribution one degree freedom. An expectation-maximization (EM) algorithm further developed from computational...

With the further advance of a new round electricity market reform, power grid companies are no longer only supply main body electric customer oriented, and replaced by power-retailing established all kinds investment subject, which makes it necessary to study how effectively control resources.In view this, this paper uses concept viscosity, proposes viscosity model company based on AHP-ENT-LSM.First consider behavior, perception, safety, switching cost, trust, social image as influencing...

To strengthen the quality management of armored equipment, it is necessary to construct a fine index system. According actual use equipment in training institution, this paper adopts Balanced Scorecard theory such system, establishes quantitative method and researches on steps evaluation. As result, provides both theoretical reference for transformation from extensive institutions.

Most of the traditional traffic accidents are caused by human factors. Among them, overspeed driving is one main causes serious accidents. Based on analysis CIDAS accident data, this paper counted speed limit road section when speeding occurred, and elaborated test scenarios methods information function warning assist system in 2021 version C-NCAP. At same time, limitations analyzed, technical route solution current for passenger cars introduced. Finally, three representative models selected...
