A computer model predicts reliably the severity and timing of drought episodes six months in advance, helping farmers choose drought-tolerant crops and minimizing economic losses. The researchers also highlight the need to maintain adequate river levels to prevent barge traffic disruptions and ensure water supply.
A University of Cincinnati computer model is being used to study the most cost-effective plans for species preservation. The model, developed by researchers Jeffrey Camm and Amy Ando, takes into account both species distributions and land values to provide a more flexible and economical approach.
Researchers at Columbia University have devised a computer model that shows how earthquakes occur in a pyramidal distribution, with one larger quake and multiple smaller ones. The model helps estimate the likelihood of future damage by analyzing the relationship between faults and earthquake distributions.
Scientists study the feedbacks between vegetation and climate using computer models to predict future climate changes. The study found that forests create warmer temperatures in subarctic regions, affecting local ecosystems.
Researchers are using sophisticated computer models to predict the dynamics of terrestrial ecosystems facing unprecedented rates of climate change. Plant species may need to migrate at speeds up to 10 times faster than historically observed, but some terrains offer less suitable habitats for this adaptation.
A computer model developed by Penn State researchers can predict the probability of land use change and microclimate formation in urban areas. The model uses satellite image data to calculate land use types, vegetation, and surface climate parameters, providing insights into urban growth and its impact on local liveability.
A new coupled hydrologic model system simulates storm events and river basin response by linking atmospheric and hydrological models. The model was tested on the West Branch of the Susquehanna River basin, showing improved results with historic meteorological data compared to atmospheric predictions.
A new Yale University study estimates the lifetime economic cost of each person to society, taking into account global warming and other factors. The study suggests that the shadow price of a person comes out to about 30% of per capita Gross Domestic Product.
Astronomers use Hubble Space Telescope images and a computer model to study the behavior of stars in their infancy, shedding light on how cosmic dust influences the environment. The findings provide new insights into the formation of solar systems and the role of powerful jets of dust and gas in shaping star formation.
A workshop at UBC brought together faculty and graduate students from the Pacific Institute for the Mathematical Sciences (PIms) with industrial partners to solve six practical problems. The team successfully identified a better way to identify cancerous lesions in lungs, reducing mortality rates.
Recent satellite data show no definitive warming trend in Earth's lower atmosphere over past two decades, contradicting computer models' predictions. The accurate temperature measurements are verified by multiple methods, including balloon-borne observations and intercalibration among orbiting platforms.
The University of Illinois will participate in a $250 million, 10-year program to develop advanced computational systems for simulating solid-propellant rockets. The center will focus on detailed whole-system simulations, benefiting both basic scientific research and aerospace applications.
Recent satellite and in-situ measurements reveal no definitive warming trend in the tropical free troposphere over the past two decades. The low humidity in this region allows more infrared radiation to escape from the Earth, cooling the atmosphere. Current computer models inaccurately handle humidity processes in this region.
The study reveals that chemical activity within brain cells exhibits behavior characteristic of self-organized criticality, which may help identify disease processes. Researchers used modeling techniques to simulate brain networks and found a power law distribution of wave sizes and durations, adhering to the signature of self-organize...
Researchers have developed a new model that accurately predicts Dungeness crab population fluctuations, combining internal and external factors. The study provides a rare instance where a modeled understanding agrees with field data, offering insights into the elusiveness of population predictability.
Scientists model 1883 tsunami impact on English Bay and Homer Spit, predicting energy absorption at Anchor Point and flooding risk at Homer Spit. The model helps emergency planners understand risks and plan for potential landslides and tidal waves.
A new software developed by UD researchers can generate a simulated version of reforming scenarios in just 100 CPU seconds, improving the accuracy and speed of modeling catalytic reforming processes. The NetGen reforming software allows researchers to build models in a day instead of months.
Scientists argue that computer models and satellites are useful tools, but only when their limitations are well understood. They found that most of the difference between MSU and surface trends could be explained by two significant drops in MSU data for 1981 and 1991.
A teleapprenticeship program is being tested in teacher education to connect students with experts, providing a learning model that benefits both on and off campus. The program has shown success in making teaching more sustainable by involving multiple people in the process.
Researchers at Oak Ridge National Laboratory created a computer model of the Ford Explorer to simulate 35 mile per hour crash tests. The model will provide information used to assure future, lighter vehicles meet safety requirements, reducing the need for expensive actual crashes.
Research from NASA and the Global Hydrology and Climate Center suggests that the temperature structure of the atmosphere is more complex than previously thought. The study found a slight downward trend in the lower troposphere since 1979, while surface measurements show a warming trend.
A computer model developed by researchers at WashU Medicine suggests that one-time carotid artery screening is beneficial for asymptomatic men with high-risk factors, preventing strokes at a relatively low cost. However, annual screening would be prohibitively expensive and may even increase stroke risk in low-risk individuals.
Researchers developed a model to explain the Earth's inner core rotating faster than the rest of the planet, driven by electromagnetic forces and outer core fluid motions. The model provides insights into the mysterious processes generating the magnetic field deep within the Earth's core.
A researcher has developed a mathematical tool to model trading patterns of stockbrokers by analyzing crowd behavior. This technique, known as Orchid Fractal Analysis, provides highly accurate models of how crowds behave, similar to modeling crowd control at football stadiums.
Researchers study sound waves traveling through the sun to probe its structure and improve solar models. The GONG data show that the sun's core spins at the same rate as its surface, a problem for understanding the solar system's formation.
