Although the exposure to PM2.5 has serious health implications, indoor monitoring is not a widely applied practice. Regulations on level and measurement schemes are well established. Compared other settings, prediction models for large office buildings particularly lacking. In response these challenges, statistical were developed in this paper predict concentration well-mixed air commercial building. The performances of different modeling methods, including multiple linear regression (MLR),...

Soft robots hold great promise but are notoriously difficult to control due their compliance and back-drivability. In order implement useful controllers, improved methods of perceiving robot pose (position orientation the entire body) in free perturbed states needed. this work, we present a holistic approach perception bending with external contact, using multiple soft strain sensors on (not collocated point contact). By comparing deviation these from value an unperturbed pose, able perceive...

Mean and peak wind speeds, as well gust factors, integral scales, intensity of turbulence values, are essential in formulating loading standards for structures. In recent years, the characterization rooftop speeds has become more important when designing photovoltaic arrays. As part an investigation into structural behavior pedestal mounted arrays, at two elevations were investigated through analysis field measurements performed Central Washington University campus Ellensburg, Washington....

According to NOAA, eleven billion-dollar weather disasters occurred in the United States 2012. One of predominant reasons that storms become is failure civil infrastructure systems, also known as “lifelines,” on which communities rely. The approach modeling resilience herein through use systems-based models performance. are based empirical evidence ability underlying structural delivery system provide essential services community. For example, electric power performance, subject extreme...

Battery pack may result in disastrous hazards if being intruded by water. However it is difficult to study on the behavior of under water due complexity this system. A supplement experiment battery immersion was proposed. charger used provide a simulated voltage and connected with single cell series. Through experiments conducted different types cells, electric arc considered as most probably cause failure immersion. The can fuse poles or shells, leading electrolyte leakage. test results...

Thermal management system (TMS) plays an essential part in improving the safety and durability of battery pack. Prior studies mainly focused on controlling maximum temperature difference Little attention has been paid to influence TMS thermal runaway (TR) prevention packs. In this paper, a heat pipe-based (HPTMS) is designed investigated illustrate both capabilities TR propagation preventing. Good performance could be achieved under discharge charge cycles 2 C rate 3 while equivalent...

In moderate climates, the operation of windows is most common way to control for thermal comfort. Window-opening behavior (WOB) a complex process influenced by multiple factors, yet only simple bi-variate analyses between variables obtained from longitudinal datasets have been examined. The goal this study investigate effects indoor and outdoor environmental parameters on WOB using statistical modeling approach called “structural equation modeling.” results show that parameters, such as...

Introducing double physical crosslinking reagents (i.e., a hydrophobic monomer micelle and the LAPONITE® XLG nano-clay) into copolymerization reaction of hydrophilic monomers N,N-dimethylacrylamide (DMAA) acrylamide (AM) is reported here by thermally induced free-radical polymerization method, resulting in highly tough rapid self-healing dual-physical poly(DMAA-co-AM) hydrogel. The mechanical properties can be finely tuned varying weight ratio nanoclay to DMAA. tensile strength elongation at...

Civil infrastructure systems play an important role in community resilience. Without proper functioning of the infrastructure, especially power delivery, society will not recover quickly from disruptive events such as hurricanes. In this paper, vulnerability, response and recovery selected at system level for several hurricanes USA are modeled using geo-statistical methods employing post-event data. Inoperability is main variable each system. robustness a property considered to be opposite...

In order to meet renewable energy goals in the near future, deployment of photovoltaic (PV) panels on buildings will dramatically increase. The objective this paper is introduce an improved design for PV cladding systems that greatly contribute meeting these goals. Typically, building-integrated (BIPV) are vertically oriented as and they not coupled with individual storage batteries. proposed couples a tilted BIPV panel one or more batteries at each building placement. Thus, plus battery...

Healthy building design guides are cogent and necessary. While elements that contribute to healthy buildings multifactorial, the perception of sound versus noise is subjective difficult operationalize. To inform commissioning process, acoustics in an open office was examined following first international certification system focuses on well-being occupants. Results highlight role facility managers play ensuring acoustical quality offer suggestions optimize rating systems. Mixed empirical...

Purpose The paper aims to develop a particle matter (PM 2.5 ) prediction model for open-plan office space using variety of data sources. Monitoring PM levels is not widely applied in indoor settings. Many reliable methods monitoring require either time-consuming or expensive equipment, thus making impractical many goal this identify possible low-cost, low-effort sources that building managers can use combination with machine learning (ML) models approximate the performance much more costly...
