Cyberinfrastructure for the collaborative development of U2U decision support tools

This paper describes the use of cyberinfrastructure to create interactive applications as part of the Useful to Usable (U2U) project. These applications transform historical climate data, knowledge, and models into decision support tools for end users such as crop farmers, uni- versity Extension edu…

Economic impacts of climate change on agriculture: A comparison of process-based and statistical yield models

A large number of studies have been published examining the implications of climate change for agricultural productivity that, broadly speaking, can be divided into process-based modeling and statistical approaches. Despite a general perception that results from these methods differ substantially, t…

Roller Compactor

The impact of material properties and process parameters are determined using a continuum model. Normal stresses for roller compaction are calculated from Johanson's rolling theory. The boundary between the slip and nip regions is calculated using Johanson's criterion, i.e. gradients of stress in sl… Launch Tool

Dynamic Roller Compactor

…it becomes possible to design, optimize, and control the process based on the model.The simulator was built using Matlab. The user can vary three input variables: roll pressure, feed speed and roll speed. They can be specified as a function of time. For example, if the roll pressure is assigned as 1*step(t-3), the simulator increases the roll pressure from 1MPa to 2MPa at t = 3 min. All Matlab functions are supported for specifying the patterns of the input variables. Dynamic simulation of roller compaction for dry granulation Launch Tool

Roughness models for particle adhesion

The effects of different surface roughness models on a previously developed van der Waals adhesion model were examined. The van der Waals adhesion model represented surface roughness with a distribution of hemispherical asperities. It was found that the constraints used to define the asperity distri…

Using spatially explicit data to improve our understanding of land supply responses: An application to the cropland effects of global sustainable irrigation in the Americas

Land supply elasticities determine the rates of land conversion in global policy models. However, they are only available for few countries in the world. Therefore, analysts seeking to improve the spatial resolution of their models are forced to impose regionally homogeneous parameters over highly h…
