Background: Energy input in agriculture has increased tremendously and accounts for about 17% of total energy consumed in the USA. Precision agriculture involves knowledge-based technical management systems to optimize application of fertilizer, chemicals, seeds, and irrigation resources to reduce input costs and to enhance crop yield while simultaneously reducing harmful environmental impacts ...
In this paper, a model predictive control (MPC)-based coordinated scheduling framework for variable wind generation and battery energy storage systems (BESSs) is presented. On the basis of the short-term forecast of available wind generation and price information, a joint look-ahead optimization is performed by the wind farm and storage system to determine their net power injection to the elect...
With the continuing pressure on Australia’s water resources and interand intra-annual rainfall variability, farmers, especially in rainfed agricultural and pastoral zones, have been developing farm dams as a mean of providing additional water sources for irrigation and stock. The density of farm dams has increased over time, and an accurate knowledge of the spatial distribution of farm dams is ...
The STAR level-3 trigger is a MYRINET interconnected ALPHA processor farm, performing online tracking of N 53!#, 58000 particles (N 10*/5 445 per track) with a design input rate of R"100 Hz. A large-scale prototype system was tested in 12/99 with laser and cosmic particle events. ( 2000 Published by Elsevier Science B.V. All rights reserved.
To the careless observer and general critic the making of a law is a very easy thing. But to the actual lawmaker who meets the usual difficulties and encounters the practical obstacles it is a very different matter, and it may be of interest to many to follow the course of a bill from beginning to end.

times, but more uncertainty seems to be hallmarks for 2008. Agriculture is experiencing the best times since the 1970s. It’s finally a boom for Indiana farmers and agribusinesses. Farm incomes are up. Equity is way up due to a 17% increase in land values. Farm families on average are on their strongest financial footing in 50 years. These better times are being driven by a worldwide surge in th...
A questionnaire survey was conducted to determine the worm control practices and anthelmintic usage of 150 key respondents involved in sheep and goat production in the arid Thal area of Pakistan. The information was collected by visiting farms, and interviewing the key respondents which included veterinary officers (n = 15), veterinary assistants (n = 51), traditional practitioners (n = 24), an...
