The evolution of tire-road wear particles and road surface texture under rolling friction

Traffic-related non-exhaust emissions are an important part of air pollution, which can adversely affect human health when inhaled. Tire-road wear is a significant source of these emissions and originates from tire-road friction. To gain a deeper understanding of the relationship between tire-road wear particles and road surface texture under rolling friction, this study conducted long-term durability experiments using a Model Mobile Load Simulator at 1/3rd scale to form a closed environmental test system. The experiments were conducted under 30°C, 50 % relative humidity, 0.7 MPa tire-ground pressure, and 5.4 km/h rolling speed. Based on an analysis of asphalt concrete-13 Marshall samples’ British Pendulum Number (BPN) value, Mean Texture Depth (MTD), wear particle size distribution, particulate matter (PM) concentration, and thermogravimetric analysis during 1600,000 rolling times, this study draws the following conclusions: This indoor research has indicated that the weight ratio of tire and asphalt wear to aggregates and mineral fillers is approximately 4.5:5.5 (after stabilization). When the tire contacts the aggregate exposed after asphalt film peeling, it significantly increases PM10 concentration. Under the rolling friction of the tire-road contact, the quality loss of asphalt concrete follows an exponential decay curve with an R2 of 0.99. Road (asphalt concrete pavement) wear per square meter of tire-road contact was 5.32×10^−4 g and 2.13×10^−4 g (before and after asphalt film peeling). It is hoped that this study will contribute to the field of tire-road wear, including non-exhaust emissions, and provide methods and theoretical support for mitigating re-suspension dust.

Uncertainty Analysis of Slug Calorimeters in the NASA HyMETS Arc-Jet Facility

The objective of this work is to perform an uncertainty analysis of the deduced stagnation heat flux environment on a slug calorimeter in the Hypersonic Materials Environmental Test System arc-jet facility located at NASA Langley Research Center. Analytical solutions are developed for boundary-value problems on the slug sensor accounting for nonideal effects, including spatial variation in the slug heat flux, multidimensional thermal conduction, and backface losses, which depart from the state-of-the-art method derived from the American Society of Testing and Materials. The analytical solutions are compared and optimized to experimental backface slug thermocouple data for a high- and low-enthalpy test condition. The results indicate that the epistemic uncertainty of the deduced stagnation heat flux on the slug calorimeter is at most ±2.5% for both conditions. Using a numerical approach to evaluate the aleatory uncertainty component in the slug stagnation heat flux, there is a compromise between the sample size and filter frequency of slug backface thermal data points when evaluating the deduced stagnation heat flux standard deviation. The total (mixed) uncertainty in the deduced stagnation heat flux is determined to be up to ±4%, which is at least a 60% reduction from the standard uncertainty used in the state-of-the-art method.

Building envelopes with radiative cooling materials: A model for indoor thermal environment assessment based on climate adaptation

To create a comfortable thermal environment in buildings, building cooling account for a large part of building energy consumption in summer. The spectral radiative properties of radiant cooling materials as a passive cooling technology have been extensively studied. However, there are few studies that address the application of radiant cooling materials to building envelopes. This paper proposed a radiative cooling glass composite structure for windows based on existing radiant cooling materials and established a climate adaptive radiant cooling building indoor thermal environment assessment model. This assessment model combines the spectral selectivity of radiative cooling materials with climate characteristics. An indoor thermal environment test system and an ambient climate measurement system are designed under the influence of external windows, and the average error of the assessment model is verified to be no more than 4.83%. Based on this assessment model, three applicability analyses were conducted: Firstly, it is concluded that the daytime indoor temperature with radiative cooling glass (RCG) is 26.43°C lower than that with the ordinary glass. Secondly, RCG can effectively improve the indoor thermal environment for rooms facing each direction, and the indoor temperature is 45.06°C lower than that of ordinary glass in the east and west directions, and 15.05°C lower than that of ordinary glass in the north and south directions. Finally, analysis of the correlation between indoor temperature and outdoor temperature shows that the indoor temperature tends to rise as the outdoor temperature rises. The analysis of the application of RCG in different cities shows that the performance of radiative cooling is relatively weak in areas with high relative humidity.

Thermal Analysis for Phenolic Impregnated Carbon Ablator/CV-1144-0 in Hypersonic Test Environments

Analysis of multidimensional in-depth thermal response for the phenolic impregnated carbon ablator (PICA)/CV-1144-0 material system in NASA Langley Research Center Hypersonic Materials Environmental Test System environments was performed using the 3-D Fully Implicit Ablation and Thermal (3dFIAT) code, which was enhanced to enable the simulation of multidimensional thin-coating burn-through and multistreams of pyrolysis gas flow. CV-1144-0 is a controlled volatility room-temperature vulcanized silicone oxygen protective coating. Three proposed in-depth thermal response models for CV-1144-0 were examined to assess their accuracy and understand how the coating affected PICA thermal performance. These proposed in-depth thermal response models were used to predict the in-depth temperature history for three groups of arcjet test models. Pyrometer surface temperature measurements and recessed surface data from laser scans were used as the boundary conditions in 3dFIAT in-depth response simulations. Data-parallel line relaxation was used to compute the surface heat flux and pressure distributions based on the surface geometries of pretest and posttest models. Comparisons between computations and thermocouple data are presented and discussed for each test model. The uncertainty of surface temperature and recession measurements on in-depth temperature prediction is investigated. The effect of CV-1144-0 coating thickness on the modeling of PICA in-depth thermal response is also studied.

Experimental study on the mechanical properties of grouted rock bolts subjected to sulfate attack and freeze-thaw cycling

This paper examined the effects of freeze-thaw cycling and sulfate attack on the pull-out capacity of rock bolts. The freeze-thaw cycling experiments consisted of alternating 4-hour freeze-thaw cycles in a high-low temperature environmental test system; some specimens were subjected to sulfate attack during freeze-thaw cycling. After exposure to a number of freeze-thaw cycles, the specimens were tested to failure. The displacement, strain and ultimate pull-out capacity of the rock bolts were determined. The experimental results show that the compressive and shear strength values of the specimens subjected to freeze-thaw cycles in pure water (PW) decreased with increasing freeze-thaw cycles, whereas in the early stage of freeze-thaw cycling, the compressive and shear strength values of the specimens subjected to freeze-thaw cycles in sulfate solution (SS) increased and then decreased. Both freeze-thaw cycling and sulfate attack reduced the bearing capacity and increased the deformation of rock bolts, which caused stress relaxation in the bolts. Moreover, both freeze-thaw cycling and sulfate attack can reduce the mechanical properties of rock bolts. Under the combined action of sulfate attack and freeze-thaw cycling, freeze-thaw damage played a dominant role. In this study, the effect of freeze-thaw damage was quick, whereas the effect of sulfate attack was slow. After a period of exposure to sulfate attack or freeze-thaw cycling, the damage from sulfate attack was greater than that from freeze-thaw cycling. Regression equations were given to estimate the bearing capacity of rock bolts subjected to sulfate attack and freeze-thaw cycling, thereby providing a method for evaluating the durability of rock bolts.

Implementation of internal quality control program for monitoring of enzyme-linked immunosorbent assay performance at a blood center

BACKGROUND:Internal quality control (IQC) samples may be incorporated in enzyme-linked immunosorbent assay (ELISA) routinely for detection of errors occurring due to change in environmental conditions, test system, or operator performance. We have described methodology for preparation of IQC samples, monitoring of results using Levey–Jennings (LJ) charts and their interpretation. We have also described our experience of quality control in ELISA using IQC samples, identification of errors and corrections applied.MATERIALS AND METHODS:IQC samples for anti-HIV, hepatitis B surface antigen (HBsAg), and anti-HCV ELISA were prepared “in-house” using standard methodology. After validation of run, E-ratio of IQC sample was calculated and plotted on LJ chart. Further interpretation was done to detect the errors. LJ charts illustrating the performance of IQC samples on 180 runs for each ELISA were drawn and analyzed.RESULTS:For anti-HIV ELISA, violation of warning rule was found in 2 runs (1.11%). Only one run (0.55%) was rejected due to violation of rejection rule. For HBsAg ELISA, violation of warning rule was indicated in two runs (1.11%). Two runs (1.11%) were rejected due to violation of rejection rules. For anti-HCV ELISA, violation of warning rule was indicated in two runs (1.11%), whereas two runs were rejected due to violation of rejection rules. Comprehensive checks were performed for the evaluation of equipment calibration, handling, and storage temperature of reagents and operator's technique. A thorough investigation was undertaken according to the type of error.CONCLUSION:Inclusion of IQC with each ELISA run is valuable to check the assay performance, ensuring reliability and reproducibility of test results.

Circuit-Based Mathematical Model of an Arc Heater for Control System Development

A novel circuit-based mathematical model of an electric arc heater is presented so that an arc heater system can be modeled, and a control algorithm can be developed and simulated. Due to inherent arc nonlinearities and complexities, as well as low amounts of arc heater data, the new model was developed by establishing a holistic approach to implementing the arc as a circuit element, where common circuit analysis and control techniques can be easily applied. The response of the arc heater system was examined at various voltage and current operating points that represent different regions of operation within the arc’s characteristic curve. The simulated data of the arc heater model were compared to the arc characteristics of the experimental data. The experimental data set used for comparison was collected at the Hypersonic Materials Environmental Test System (HyMETS) arc-jet wind tunnel by the NASA Langley Research Center in Hampton, Virginia. Data analysis and simulations were executed utilizing MATLAB and Simulink to compare the newly developed model with the experimental data. The simulations demonstrate a strong correlation between these datasets, indicating the model’s ability to accurately replicate the physical system, while also allowing initial control system development to begin with simplistic proportional-integral-derivative (PID) control of the arc heater.

Calibration Probe Uncertainty and Validation for the Hypersonic Material Environmental Test System

This paper presents an uncertainty analysis of the stagnation-point calibration probe surface predictions for conditions that span the performance envelope of the Hypersonic Materials Environmental Test System facility located at NASA Langley Research Center. A second-order stochastic expansion was constructed over 47 uncertain parameters to evaluate the sensitivities, identify the most significant uncertain variables, and quantify the uncertainty in the stagnation-point heat flux and pressure predictions of the calibration probe for low- and high-enthalpy test conditions. A sensitivity analysis showed that measurement bias uncertainty is the most significant contributor to the stagnation-point pressure and heat flux variance for the low-enthalpy condition. For the high-enthalpy condition, a paradigm shift in sensitivities revealed the computational fluid dynamics model input uncertainty as the main contributor. A comparison between the prediction and measurement of the stagnation-point conditions under uncertainty showed that there was evidence of statistical disagreement. A validation metric was proposed and applied to the prediction uncertainty to account for the statistical disagreement when compared with the possible stagnation-point heat flux and pressure measurements.

SMART-Navigation over Pilot LTE-Maritime: Deployment and Coexistence with PS-LTE

The SMART-Navigation project aims to develop a next-generation maritime safety integrated management system based on the e-Navigation concept of the IMO. The purpose of the pilot LTE-Maritime project is to construct test zones and establish effective LTE-Maritime plans based on the pilot test results. The spectrum band for LTE-Maritime system is the licensed public radio frequency band over 718-728 MHz for UL and 773-783 MHz for DL, but this band is shared with the Public Safety LTE (PS-LTE) and LTE-Railway (LTE-R) systems. Because these systems share the same spectrum band, CCI from PS-LTE and LTE-R arises during the Pilot LTE-Maritime test. To resolve this issue, we perform a test on the East Sea (around the city of Gangneung) in Korea with the proposed radio access network RAN-Sharing technique. In addition to the proposed RAN-Sharing technique, this article addresses the system architecture, requirements, test environment, and results of the LTE-Maritime system.

A Novel On-Line Substation Instrument Transformer Health Monitoring System Using Synchrophasor Data

Substation asset health has always been one of the utmost concerns for utilities. The substation secondary assets such as current transformers, potential transformers, and coupling capacitor voltage transformers play vital roles for system situational awareness and grid operations. This paper proposes a novel on-line substation instrument transformer health monitoring system (SITHMS), which merely uses time-synchronized and high-resolution phasor measurement unit (PMU) data. The SITHMS can provide early warning and alert utility personnel to diagnose the equipment malfunction and take proactive actions for asset management to prevent equipment failure. The core component of the SITHMS is a model-based three-phase substation-level linear state estimator, which features a built-in largest normalized residual (LNR) module that can detect anomalies in PMU data by using substation model and configuration, so as to probe if there is malfunction or potential failure of these secondary equipment. In addition, we present the system's implementation architecture and testing environment setup. Case studies with the PSCAD simulated data and field PMU data from actual substations at American Electric Power (AEP) demonstrate the effectiveness of the proposed system.

Whole slide imaging equivalency and efficiency study: experience at a large academic center

Whole slide imaging is Food and Drug Administration-approved for primary diagnosis in the United States of America; however, relatively few pathology departments in the country have fully implemented an enterprise wide digital pathology system enabled for primary diagnosis. Digital pathology has significant potential to transform pathology practice with several published studies documenting some level of diagnostic equivalence between digital and conventional systems. However, whole slide imaging also has significant potential to disrupt pathology practice, due to the differences in efficiency of manipulating digital images vis-à-vis glass slides, and studies on the efficiency of actual digital pathology workload are lacking. Our randomized, equivalency and efficiency study aimed to replicate clinical workflow, comparing conventional microscopy to a complete digital pathology signout using whole slide images, evaluating the equivalency and efficiency of glass slide to whole slide image reporting, reflective of true pathology practice workloads in the clinical setting. All glass slides representing an entire day's routine clinical signout workload for six different anatomic pathology subspecialties at Memorial Sloan Kettering Cancer Center were scanned on Leica Aperio AT2 at ×40 (0.25 µm/pixel). Integration of whole slide images for each accessioned case is through an interface between the Leica eSlide manager database and the laboratory information system, Cerner CoPathPlus. Pathologists utilized a standard institution computer workstation and viewed whole slide images through an internally developed, vendor agnostic whole slide image viewer, named the “MSK Slide Viewer”. Subspecialized pathologists first reported on glass slides from surgical pathology cases using routine clinical workflow. Glass slides were de-identified, scanned, and re-accessioned in the laboratory information system test environment. After a washout period of 13 weeks, pathologists reported the same clinical workload using whole slide image integrated within the laboratory information system. Intraobserver equivalency metrics included top-line diagnosis, margin status, lymphovascular and/or perineural invasion, pathology stage, and the need to order ancillary testing (i.e., recuts, immunohistochemistry). Turnaround time (efficiency) evaluation was defined by the start of each case when opened in the laboratory information system and when the case was completed for that day (i.e., case sent to signout queue or pending ancillary studies). Eight pathologists participated from the following subspecialties: bone and soft tissue, genitourinary, gastrointestinal, breast, gynecologic, and dermatopathology. Glass slides signouts comprised of 204 cases, encompassing 2091 glass slides; and digital signouts comprised of 199 cases, encompassing 2073 whole slide images. The median whole slide image file size was 1.54 GB; scan time/slide, 6 min 24 s; and scan area 32.1 × 18.52 mm. Overall diagnostic equivalency (e.g., top-line diagnosis) was 99.3% between digital and glass slide signout; however, signout using whole slide images showed a median overall 19% decrease in efficiency per case. No significant difference by reader, subspecialty, or specimen type was identified. Our experience is the most comprehensive study to date and shows high intraobserver whole slide image to glass slide equivalence in reporting of true clinical workflows and workloads. Efficiency needs to improve for digital pathology to gain more traction among pathologists.

A general experimental system for the development of acoustic logging tools.

Laboratory testing is a pre-requisite for the practical application of new methods and techniques, and it is crucial in the research and development of acoustic well-logging tools. Various tools have been developed based on different acoustic logging theories and methods. Thus, these tools are equipped with different acoustic sonde structures. To meet the test requirements of different tools in a laboratory environment, we designed a general experimental system that includes hardware platform, software platform, and model wells according to the common structure of actual logging tools. Similar to the internal electrical structure of downhole tools, the hardware platform consists of several main parts, such as power supply, control and telemetering, acoustic emission, and data acquisition. The functions of this hardware platform include controlling the working sequence of the experiment, exciting the transmitter sonde, and collecting the acoustic signals received by the receiver sonde. The software platform installed in the host computer provides a human-computer interface for the experimental system to complete the data transmission between the host computer and the hardware platform, store measured data, and process the data in real time. The model wells approximate the actual engineering environment and stratum condition for system testing. A series of practical laboratory experiments is conducted in the model wells by using this experimental system. The process proves that the hardware and software of the experimental system can work in coordination, and the experimental system meets the basic testing requirements of conventional acoustic logging tools.

Experimental study on the thermal performance of solar air conditioning system with MEPCM cooling storage

Solar powered air conditioning system is a hot issue in the study field of building energy conservation. An experimental platform of solar powered air conditioning with microencapsulated phase change material (MEPCM) cooling storage system was carried out to evaluate the efficiency of the solar powered air conditioning system and the coupled relation with the solar radiation intensity. The outdoor and indoor environmental test system was used to collect the performance parameter data of test room to verify the cooling energy storage effect. The solar air conditioning combined with MEPCM cold storage system which was tested in Chengdu city, China. According to the analysis result, the transient thermal efficiency would decline with the rising normalized temperature difference. The transient thermal efficiency has the same variation trend with the solar radiation. The indoor air temperature of the test room was maintained between 18°C and 22°C. MEPCM cold storage system could maintain the indoor air temperature in the stable range. The energy saving rate of the completed system could reach at 30.5%. The research result could help to improve the study of solar powered air conditioning system and its application.

Prediction on residual stresses of carbon/epoxy composite at cryogenic temperature

In this article, the elastic modulus and coefficient of thermal expansion of bisphenol F epoxy resin from room temperature to cryogenic temperature (−180°C) were tested through a cryogenic environment test system. The elastic modulus of carbon/epoxy composite at room and cryogenic temperature was also tested. The measured temperature‐dependent material parameters are used as the input of a 3D micromechanical finite element model of fiber‐reinforced polymer matrix composite, considering random fiber distribution. The longitudinal and transversal elastic modulus of the carbon/epoxy composite is predicted by the present model, with good agreements between the predicted and experimental results. Then the residual stresses of carbon/epoxy composite due to cryogenic temperature are predicted by this model. It is found that high residual stress occurs in the matrix between two adjacent fibers. The longitudinal residual stress is compressive in fibers but tensile in matrix. The transversal stress in fibers is mainly compressive, and there is comparable transversal tensile and compressive stress in matrix. The maximum residual stress in the composite is the longitudinal tensile stress in matrix. This work can lay a foundation for the design and application of polymer–matrix composites in cryogenic environment. POLYM. COMPOS., 40:3412–3420, 2019. © 2019 Society of Plastics Engineers

A realistic laboratory development of an isolated wind-battery system

This paper details the methodology and development of an isolated wind-battery system in the lab. The full-scaled prototype was built using commercial components along with the assistance of a hardware-in-the-loop system. The integration and characterisation of a wind energy conversion system in an off-grid power system are also elaborated. Droop-based inverters interfacing batteries were used to form the isolated grid whilst a fixed speed wind turbine was employed as the main source of power generation. The former is known to be autonomous and function without communication system whilst the latter employs a squirrel cage induction generator which is robust, simple to operate and requires minimal maintenance. They were selected with the aim to reduce the technical problems which may be faced by the communities where technical assistance is scarce. We have shown that the proposed methodology presents a more controlled environment for system testing and integration whilst reproducibility of measurements can be achievable in parallel. The performance and electrical dynamics of the isolated wind-battery system are analysed with simulations and experiments. Finally, we present the capability of the test-rig in emulating the non-ideal tower shadow effect of a wind energy system.
