Abstract (sommario):

The daily and within-day variation in udder temperature was monitored in dairy cows (n = 10) using infrared thermography (IRT). The initial assessment and prediction of udder surface temperature variation would hopefully form the basis for future development of an early detection method for mastitis. Our initial objective was to determine the magnitude and pattern of udder temperature variation. To accomplish this, we measured daily fluctuations in udder temperature and the influence of environmental factors upon these values in non-mastitic cows. Udder temperature rose significantly after an

Abstract Rail track derailment has been proven to be the cause of most of the rail accidents in recent years. High-temperature strains in railways caused by rail traction and thermal variation are the main causes of derailment, which lead to buckling. The likelihood of passenger deaths and maintenance costs will be reduced if thermal strains and failure in rails are detected early. This research attempts to provide a preventative strategy for detecting thermal strains and deformation caused by temperature fluctuations at railways. Using the electromechanical impedance (EMI) technique, piezoele

Abstract In Lamb wave-based structural health monitoring (SHM), the environmental temperature variations can easily affect Lamb wave monitoring signals and seriously reduce the reliability of final damage detection results. To resolve the temperature effect problem, a temperature compensation method of improved baseline signal stretch (IBSS) is presented and applied for high reliability damage imaging under large environmental temperature variations in this paper. After the basic principle of IBSS is analyzed, the realization of IBSS is discussed. Then, a IBSS-based high reliability damage ima

Abstract (sommario):

The aims of this project were (i) to monitor the seasonal variation of environmental conditions at stress corrosion cracking (SCC) sites and (ii) to develop an improved site-selection model for SCC. Environmental and other relevant data have been collected for a total of nine known, or suspected, SCC sites; seven near-neutral pH SCC and two high-pH SCC.� The presence of SCC was determined, or predicted, based on in-service or hydrotest failures, excavation, industry soils model, or ILI.� Pipe-depth environmental conditions were monitored continuously for periods of up to 2 years using the perm

Abstract (sommario):

In 2005 the National Park Service (NPS) Southeast Coast Network (SECN) Inventory and Monitoring Program began collecting water-quality data in the estuarine waters near Cape Hatteras National Seashore (CAHA) as part the NPS Vital Signs monitoring program. The continuous monitoring data station is located at a dock at the Ocracoke Village boat ramp. This station collects pH, dissolved oxygen, temperature, salinity, conductivity, turbidity and water level data every 30 minutes. Additional water quality measurements are made by SECN staff and include monthly measurements of water clarity conditio

Abstract (sommario):

Distributed Acoustic Sensing (DAS) is a fiber optic sensing system that is used for vibration monitoring. At a minimum, DAS is composed of a fiber optic cable and an optic analyzer called an interrogator. The oil and gas industry has used DAS for over a decade to monitor infrastructure such as pipelines for leaks, and in recent years changes in DAS performance over time have been observed for DAS arrays that are buried in the ground. This dissertation investigates the effect that soil type, soil temperature, soil moisture, time in-situ, and vehicle loading have on DAS performance for fiber opt

Abstract (sommario):

Water quality was monitored in Waikolu Stream, Kalaupapa National Historical Park, Moloka?i, Hawa?i from 2007-2017. Water was collected for nutrient analyses and a sonde equipped with multiple probes was used to measure water quality parameters. The sampling regime was based on a split-panel of permanently established or ?fixed? sites sampled during each sampling effort, and ?temporary? sites of randomly assigned locations, for each sampling effort. Results included: ? NO-3 + NO-2 regularly exceeded state water quality criteria. ? TP exceeded state water quality criteria once out of three quar

Abstract (sommario):

The engineering behavior of frozen soils is critical to the serviceability of civil infrastructure in cold regions. Among various geophysical techniques, electrical resistivity imaging is a promising technique that is cost effective and provides spatially continuous subsurface information. In this study, under freeze–thaw conditions, we carry out lab–scale 1D electrical resistivity measurements on frost–susceptible soils with varying water content and bulk density properties. We use a portable electrical resistivity meter for temporal electrical resistivity measurements and thermocouples for t

Abstract (sommario):

Particulate matter (PM) pollution poses significant health risks, influenced by various meteorological factors and seasonal variations. This study investigates the impact of temperature and other meteorological variables on PM10 and PM2.5 levels in Fresno County, known for high air pollution. Multiple linear regression (MLR) and generalized additive models (GAMs) assess the significance of these relationships. Analyzing data from Fresno County, we examine PM10 and PM2.5 levels across "hot" (June to August) and "cool" (September to May) seasons. Findings indicate PM10, both MLR and GAM models i

Abstract (sommario):

The CP criteria for buried piping systems are not consistent in different global CP standards. For instance, the standard of the International Standard Organization (ISO) and the European standard (EN) offer more specific CP criteria with respect to environmental conditions such as soil resistivity, aeration, presence of bacteria, pipe temperature and overprotection. However, they do not have the -850 mV on-potential criterion contained in the NACE Standard SP 0169-2007. The Australian National Standard (SAA) recommends the use of coupons or an electrical resistance (ER) probe in conjunction w
