Deep-Plowing Experiment
W hat constitutes “long-term” research may be as apparent as collectable art; although many are quick to identify the plots in Rothamsted-UK, started in 1843, as the gold standard of long-term research. When researchers conduct experiments in reference to a hypothesis that determines treatment application, the test duration usually lapses after a few “climatically representative” years. Mr. O. ...

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
Multi-Unit Auctions
We survey experimental research on multi-unit auctions with an emphasis on topics that may be of a unifying interest to experimental, as well as theoretical and empirical economists. Topics include static and dynamic multi-unit auctions; combinatorial auctions and efficient auction design; simultaneous and sequential auctions; bidder asymmetry and endogenous entry, and collusion in auctions. We...
متن کاملSynchronized arc routing for snow plowing operations
This paper introduces a synchronized arc routing problem for snow plowing operations. In this problem, routes must be designed in such a way that street segments with two or more lanes in the same direction are plowed simultaneously by different synchronized vehicles. A mixed integer formulation and an adaptive large neighborhood search heuristic are proposed. The performance of the proposed al...
متن کاملDiesel Fuel Consumption During Chisel Plowing
Introduction Direct energy expenses (diesel, gasoline, propane, electricity) total more than $1 billion annually for Iowa farmers. Farm management techniques such as adjusting tractor gear and throttle settings or reducing tillage depths can reduce diesel fuel consumption for row crop production. This study is being conducted over multiple years to measure the effects of energy management techn...
