1 like•327 views
The document summarizes research estimating water surface temperature in Devils Lake, North Dakota using the split window algorithm with Landsat 8 thermal infrared bands. The algorithm uses brightness temperature from the bands and coefficients accounting for atmospheric effects to calculate surface temperature. The estimates were validated against buoy observations and hydrodynamic models of the lake, with calibrated streamflow and hourly water temperature simulations showing good agreement to field data. Satellite imagery provides spatially detailed skin temperature estimates while models offer higher temporal resolution and temperature profiles.

1) The study aims to determine if maximum temperatures can be related to soil moisture levels by analyzing temperature, latent heat, and soil moisture data from flux towers in the western US.
2) It finds that days with low latent heat and high maximum temperatures statistically have drier soils than days with high latent heat and high maximum temperatures at two forest sites, but the opposite at one site.
3) Linear regression models using temperature and precipitation better capture latent heat than models using just soil moisture, showing soil moisture's influence depends on other factors like precipitation.

This document presents a novel approach for classifying groundwater systems using time series data from monitoring wells. The approach uses principal component analysis and clustering algorithms to group similar groundwater hydrographs based on features like mean, standard deviation, and maximum levels. This produces a more systematic and data-driven classification than previous subjective expert methods. The goal is to predict groundwater behavior at unmonitored locations and improve groundwater modeling and assessment of climate change impacts. The developed groupings could also provide clearer definitions of classifications like "slow and fast responding" groundwater systems.Epa ord aeh sv11

Climate statisticians analyze observational climate data and model simulations to detect trends, attribute causes, and quantify uncertainties. They use statistical methods like linear regression to attribute observed warming to human and natural factors. They also use extreme value theory to describe rare weather events and project how these extremes may change with continued warming. A key task is quantifying various sources of uncertainty in climate projections, like different model sensitivities and emissions scenarios.VI Presentation cmf
This document discusses vapor intrusion, which occurs when volatile chemicals migrate from contaminated soil or groundwater into overlying buildings. It explains what vapor intrusion is, why it should be addressed, how it is investigated through sampling soil gas, groundwater and indoor air, and how mitigation systems like sub-slab depressurization can be used to fix vapor intrusion problems. The document also provides an example of vapor intrusion impacting homes in Newark, New Jersey that were built over contaminated soils and groundwater.
Coupled heat and water transport in the vadose zone
This document summarizes research on coupled heat and water transport in bare soils. It outlines the theory of Philip and de Vries, describes field data collected, and calibration of the Hydrus-1D model. Both liquid water and water vapor fluxes are examined. Implementation of water vapor flow in the SWAP model is discussed. Comparisons of coupled and liquid-only models show little difference at daily timescales. A proposed laboratory experiment is described to further study these processes.

This document reviews research on using nanofluids to improve the performance of flat plate solar collectors. Nanofluids are fluids containing nano-sized particles that can enhance heat transfer properties. Several studies have found that nanofluids can increase heat transfer coefficients and collector efficiencies compared to using plain water. Specifically, alumina, copper oxide, and carbon nanotubes dispersed in water have shown efficiency improvements of up to 29% relative to water alone. Higher nanofluid concentrations and lower flow rates tend to increase efficiency, up to an optimal point. Overall, the literature demonstrates that nanofluids have promising potential to enhance flat plate solar collector performance.

This document describes how rainfall estimates are created from raw radar data at the National Centers for Environmental Information (NCEI). It explains that multiple radars are combined and merged to get nationwide coverage with 2 minute resolution on a standardized grid. Raw radar returns are cleaned of contamination from birds and other sources. The vertical radar scans are integrated into a single rainfall estimate. The final product provides a consistent, high quality rainfall estimate compared to the original radar data which had poorer spatial and temporal resolution and quality issues.9oct 2 fabbri-hydrogeological spring
This document summarizes a presentation on the hydrogeological characterization of springs in the Vajont area of Italy. It describes isotopic analyses conducted on the Le Spesse and Ega Nass springs which show seasonal isotopic inversion, indicating winter infiltration. Monitoring of the Le Spesse spring showed a positive correlation between rainfall and discharge lagged by one day. Conceptual modeling found the spring has a homogenization type response, slow deep reservoir circulation, and a combination of fissured/porous and limited karst circulation influences on spring composition. The V.E.S.P.A. index assessed the Le Spesse spring vulnerability as medium.

The document summarizes literature on methods to increase hydraulic capacity at wastewater treatment plants during wet weather and practical experiences from Avedøre Wastewater Treatment Plant. Operational and process changes like step feed operation, return activated sludge control, and aeration tank settling can be used. Physical modifications include water storage. Evaluating advanced controls and aeration tank settling at Avedøre found hydraulic capacity increased up to 150% in winter and 67% in summer, with reductions in effluent COD, SS, and TP concentrations and electricity savings of 7-12%.
Soil Moisture 202: Choosing the Right Water Potential Sensor
by Leo Rivera, METER Research Scientist
Water potential is the most fundamental and essential measurement in soil physics because it describes the force that drives water movement. Making good water potential measurements is largely a function of choosing the right instrument and using it skillfully. In an ideal world, there would be one instrument that simply and accurately measured water potential over its entire range from wet to dry. In the real world, there is an assortment of instruments, each with its unique personality. Each has its quirks, advantages, and disadvantages. Each has a well-defined usable range.
Which sensor is right for you?
In this 20-minute webinar, METER research scientist Leo Rivera discusses how to choose the right field water potential sensor for your application.
Learn:
• Why you should measure water potential
• Which part of the water potential range each sensor measures
• The technology behind each method: tensiometers, granular matric sensors, heat dissipation sensors, thermocouple psychrometers, and capacitance sensors.
• The pros and cons of each method
• Which sensors are best for certain applications
Measurement and estimation of different environmental variables
Measurement and estimation of different environmental variablesPMAS Arid Agriculture University Rawalpindi, Pakistan
Various instruments were used to measure environmental variables including a thermometer in a Stevenson screen, thermocouples connected to a data logger, a rain gauge, a rotating cup anemometer, a Kestrel 2500 hand-held weather meter, a sonic anemometer, a hygrometer, lux and light meters, and a Penman-Monteith equation requiring daily temperature, wind speed, humidity and solar radiation inputs to predict evapotranspiration. Additional instruments included a pyranometer, Campbell-Stoke Sunshine recorder, and Accupar to measure factors like solar radiation, sunshine, and photosynthetically active radiation.15 evaporation transpiration sublimation
This document discusses various processes by which water changes phase from liquid to gas, including evaporation, transpiration, and sublimation. It provides details on the factors that control evaporation rates, such as energy inputs, temperature, humidity, wind, and water availability. It explains the differences between potential evapotranspiration (PET) and actual evapotranspiration (AET). Transpiration from plants and how it is affected by various environmental factors is also covered. Common methods for measuring and estimating evaporation and evapotranspiration are presented.
REU Poster Kubiniec
This study measured surface temperatures at sites with high and low tree canopy cover in Portland, Oregon. Thermal images found that surfaces with low canopy cover had higher temperatures across all land cover types compared to those with high canopy cover. Specifically, roof tops had the highest temperatures, which likely contributes greatly to thermal pollution in urban runoff. The methodology using thermal image analysis to catalog surface temperatures proved to be rapid, repeatable, and higher resolution than conventional methods. Continued analysis of the influence of land cover types on air and runoff temperatures is planned using satellite imagery and temperature data.

This document contains a plot file of high 3-hour air pollution concentration values from all sources in a modeling project. The plot shows contour lines of different pollution levels up to a maximum of 0.22947 micrograms per cubic meter. Receptor and modeling details are also included.Lecture 19, marine seismic surveying
Marine seismic acquisition uses airgun arrays as seismic sources to generate acoustic pulses that penetrate the seafloor. Summing the signals from multiple airguns in an array creates a more desirable signal for seismic imaging. Reflections from interfaces in layered subsurface structures, such as the seafloor and water surface, can generate multiples and ghosts that distort the primary reflections needed for seismic interpretation if not properly addressed. Hydrophones placed in the water column detect the returning acoustic pulses and convert the varying water pressure into electrical signals using the piezoelectric effect.
Air Quality Analysis in East Texas.pptx
This document analyzes air quality data from 255 stations in East Texas, focusing on the correlation between ozone, nitrogen oxides, elevation, and temperature. Statistical analysis methods like zonal statistics, ordinary least squares regression, and geographically weighted regression show that nitrogen and elevation are highly correlated with ozone levels in the study area, though temperature does not have global significance across the entire region. The small size of the study area and data inputs limit the conclusions that can be drawn.
Sed 3 Equipment Procedures And Sampling
The document describes the water quality monitoring equipment, procedures, and sampling methods used at Soaring Eagle Dairy to assess annual nutrient and sediment losses. Key monitoring equipment included an H-flume to measure surface water runoff volume, a pressure transducer and datalogger to record water levels, and an automated refrigerated sampler to collect water samples during runoff events. Samples were analyzed for parameters like suspended sediment, nitrogen, phosphorus, and more. Regular maintenance was needed to keep equipment functioning properly throughout the year.
Capstone project presentation

The project aims to optimize a thermoelectric generator's efficiency through increasing concentration ratios and determine the necessary mass of thermal storage required. Key leads include Bowen Guan on thermoelectric generation, Roshni Khetan on thermal storage, and Kyle LeBlanc on energy balancing. The document outlines experiments on improving TEG performance and selecting appropriate salt for latent heat storage.
HEAT TRANSFER ENHANCEMENT BY USING NANOFLUID JET IMPINGEMENT
This document presents an experimental study on heat transfer enhancement using nanofluid jet impingement. Key findings include:
1) The use of nanofluids (Al2O3-water) can increase heat transfer coefficients by up to 44% compared to using water alone.
2) Heat transfer coefficients are highest near the stagnation point and decrease further from the center.
3) Varying the nozzle-to-plate distance (Z/D ratio) between 2-8 results in maximum heat transfer, with little effect beyond Z/D of 12.
4) Increasing the flow rate leads to higher heat transfer coefficients, up to a 5% increase from 2 lpm to 4 lpm.
MUSE
This study aimed to calibrate the peak flow coefficient (C value) used in the NRCS dimensionless unit hydrograph equation for watersheds in New Jersey. The researchers calculated C values for watersheds less than 20 square miles using historical rainfall and flow data. C values ranged widely from 360 to 765, varying significantly even over short distances. The study found no clear regional patterns and that assuming a constant C value of 484 could produce inaccurate peak flow predictions. More precise locally calibrated C values should improve design of hydraulic structures in New Jersey.
Precautions cold weather
This document discusses precautions taken for concreting in sub-zero temperatures. It recommends selecting cement that hydrates fast to generate early heat, using admixtures like calcium chloride or sodium chloride to lower the freezing point of water and accelerate hydration, insulating concrete to preserve heat during curing, and employing air entraining agents to increase durability against frost damage by modifying the pore structure. Heating materials like aggregates and mixing water is also suggested to maintain the concrete above freezing during the pre-hardening period.
Lehrman GRA Poster_Feb 2015
Natural gas gathering operations in the Sacramento Basin have resulted in limited impacts to shallow groundwater. At most sites, detectable BTEX compounds in soil and groundwater are low or nonexistent. Groundwater plumes are small (<400 feet) and stable or shrinking over time. While diesel-range organic concentrations exceed water quality standards at all active sites, they are primarily degrading to non-hydrocarbon polar compounds through natural biodegradation processes. As a result of intrinsic biodegradation and natural attenuation, the majority of condensate releases from natural gas gathering facilities has been degraded, with less than 10% of the original mass remaining at most sites according to soil and groundwater concentration mapping and mass estimates.

The document discusses advances in simulation capabilities for complex geothermal processes using the ADGPRS and DARTS simulation platforms. ADGPRS started as a research simulator and has expanded capabilities to include geomechanics, fractures, and chemical interactions. DARTS improves performance further using an operator-based linearization approach on CPU and GPU. Recent applications include modeling of acidizing wells, fracture propagation, uncertainties in geothermal reservoirs, and high-enthalpy geothermal processes. DARTS has demonstrated orders of magnitude better performance than ADGPRS while maintaining accuracy.
A study of himreen reservoir water quality using in situ
This document summarizes a study of the water quality of Himreen Reservoir in Iraq using remote sensing techniques and in situ measurements. Satellite images from 1989 and 2002 were analyzed to study parameters like turbidity and suspended sediments. Water samples from 12 locations were also tested. The results show a correlation between higher reflectance in images and higher turbidity. The reservoir water was found to be of medium salinity and good quality. A comparison of the two years showed less shallow water and suspended sediments in 2002, likely due to changes in climate and river flow.

Satellite imagery from 1999-2015 was used to calculate Normalized Difference Vegetation Index (NDVI) values, showing increases in urban infrastructure over time. Temperature data from 1999-2015 from three monitoring stations - one mostly forested watershed (Cedar Creek) and two with varying degrees of urban/farmland (Slab Cabin Run Upper and Lower) - was analyzed. Results showed Slab Cabin Run frequently exceeded the maximum temperature range for trout survival, while Cedar Creek exceeded this temperature only once, indicating urban runoff is degrading stream habitats.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/
DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
Diese Themen werden behandelt
- Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten
- Wie funktionieren CCB- und CCX-Lizenzen wirklich?
- Verstehen des DLAU-Tools und wie man es am besten nutzt
- Tipps für häufige Problembereiche, wie z. B. Team-Postfächer, Funktions-/Testbenutzer usw.
- Praxisbeispiele und Best Practices zum sofortigen Umsetzen

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
