Abstract Nano-SiO 2 is a non-toxic, tasteless, and pollution-free material with hydroxyl groups that facilitate the adsorption of water on its surface. characterized by small particle size, high purity, low density, large surface area, good dispersion properties. In addition, nano-SiO has excellent stability, reinforcement, thixotropy, optical mechanical The additive can enhance properties microstructure concrete. Therefore, widely used as an in field building materials. Geopolymers have...

The real-time and accurate prediction of road traffic states is the basis information service for participants. An algorithm based on kernel K-nearest neighbors (kernel-KNN) presented to predict in time series this paper. First, representative state data are extracted build running characteristics reference sequences. Then, function sequence constructed. current referenced sequences matched, which k nearest selected predicted. Several typical links Beijing considered a case studies. final...

In this paper, the polarization of an oxygen electrode in rechargeable lithium batteries was investigated and found to be closely related fading discharge capacity ceasing cycling. Electrochemical tests showed that with catalyzed air electrode, cell could deliver a high initial carbon rapid at fourth cycle. When cycled restricted depth discharge, cycle life prolonged. impedance spectra responses scanning electron microscopy observations indicated discharged product block pathway, increase...

Solar absorbing and thermal storage ceramics are multifunctional materials that feature a high absorptivity surface to absorb sunlight, converting light energy into storing it through density conductivity. In this study, corundum-mullite composite absorption integrated were prepared using Fe2O3 CuO as additives. The effect of the Fe2O3-CuO additives on microstructure various physical properties was investigated. It has been shown Fe ions enter corundum lattice, leading distortion which...

Urban building energy modeling (UBEM) is arousing interest in modeling, which requires a large dataset as an input. Building use critical parameter to infer archetype buildings for UBEM. This paper presented case study determine city-scale by integrating the Geographic Information System (GIS) based point-of-interest (POI) and community boundary datasets. A total of 68,966 footprints, 281,767 POI data, 3367 boundaries were collected Changsha, China. The primary was determined when inside...

Commercial prototype building models were developed by the United States Department of Energy (DOE) to analyze energy savings ASHRAE 90.1 standard. However, in DOE models, occupant behavior inputs deterministic and stochasticity was not fully characterized. This study evaluated impacts stochastic on consumption analysis from upgrading 90.1-2016 2019 sixteen climate zones (U.S.). Three styles (austerity, normal, wasteful) defined represent different levels consciousness. The medium office...

Energy saving in buildings is essential as buildings’ operational energy use constitutes 30% of global consumption. Urban building modeling (UBEM) effectively understands urban This paper applied UBEM to assess the potential peak demand reduction and a mixed-use community, using 955 residential buildings, 35 office 7 hotels Shenzhen, China, case study. The type period were collected based on GIS dataset. Then, baseline models generated by tool—AutoBPS. Five scenarios analyzed:...

We prove the pathwise Strichartz and local smoothing estimates for a general class of stochastic dispersive equations with linear multiplicative noise, including especially Schrödinger Airy equations. The upper bounds high integrability random constants in these are also obtained. These have several applications to nonlinear problems, well-posedness $\mathbb{P}$-integrability solutions. Furthermore, large deviation principle small noise asymptotics is derived both inhomogeneous variable...

Spatial atomic layer deposition (SALD) is a promising technology with the aim of combining advantages excellent uniformity and conformity temporal (ALD), an industrial scalable continuous process. In this manuscript, experimental numerical combined model atmospheric SALD system presented. To establish connection between process parameters growth efficiency, quantitative on reactant isolation, throughput, precursor utilization performed based separation gas flow rate, carrier mass fraction....

Iron(II,III) oxide (Fe3O4) nanoparticles have shown great promise in many magnetic-related applications such as magnetic resonance imaging, hyperthermia treatment, and targeted drug delivery. Nevertheless, these are vulnerable to oxidation magnetization loss under ambient conditions, passivation is usually required for practical applications. In this work, a home-built rotating fluidized bed (RFB) atomic layer deposition (ALD) reactor was employed form dense uniform nanoscale Al2O3 layers on...

Building performance simulation can be used for retrofit analysis. However, it is time-consuming to create building energy models existing buildings. This paper presented and implemented a rapid modeling method buildings by using prototype automatic model calibration analysis with uncertainty. A shopping mall located in Changsha, China, was selected as case study demonstrate the method. First, toolkit named AutoBPS-Param developed generate parameterized geometry data. baseline EnergyPlus...
