Writing in the September 2009 issue of Resource: Engineering & Technology for a Sustainable World, Allen L. Thompson, Associate Professor of Biological and Agricultural Engineering at the University of Missouri, introduces a web-based, computer-assisted tool that may reduce the time currently required for the task by as much as half.
The new tool is intended to facilitate terrace installation on complex fields, to satisfy conservation goals and make better use of federal and state cost-share dollars. Contractors, landowners, and resource conservation personnel will benefit with the ability to select the most efficient and cost-effective terrace layouts.
Current terrace layout methods are time consuming. Rarely is it practical to develop more than one design that can be compared side-by-side for cost, conservation effectiveness, and farmability. Thompson's program will lessen design time by taking information about boundaries, desired row spacing, equipment requirements, water flow and other considerations and quickly producing several layout options.
Because the system is internet-based, it has the advantage of utilizing uploadable topographic data collected with global positioning systems. "It also provides a centralized database that is regularly updated," Thompson writes, "ensuring easy access to the most current data for soils and topography." Ongoing revisions to the program will permit the use of light detection and ranging (LIDAR) data, with the eventual goal to include calculation of cut and fill volumes and predicted soil loss.
Thompson's program builds on other tools developed in recent decades, taking design capabilities to a greater sophistication. Automated terrace layout has been slow in development, he explains, because of the complexity of the calculations required and the lack of high-precision digital elevation data. "However, LIDAR is becoming more readily available, and web resources have greatly improved in the last few years, both of which have helped generate interest and research support in this area."
Beta testing of the program is currently underway, after which the it will be available to the public.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
