Wind-tunnel experimentswere conducted on a 47-deg sweep, scaled 1303unmanned air vehiclemodel to assess the performance of an innovative windward-surface plasma actuator design for flight control at low angles of attack. Control was implemented by altering the flow past an aft separation ramp on the windward side using a single dielectric barrier discharge plasma actuator. The influence of ramp...

This paper develops an analytical framework for ramp metering, under which various ramp control strategies can be viewed as ramifications of the same most-efficient control logic with different threshold values, control methods, and equity considerations. The most-efficient control logic only meters the entrance ramps nearest critical freeway mainline sections so as to eliminate freeway interna...

In this paper we explore and extend the design space of the recent RAMP (Read Atomic Multi-Partition) transaction system for large-scale partitioned data stores. Arriving at a mature distributed system design through implementation and experimental validation is a labor-intensive task, so that only a limited number of design alternatives can be explored in practice. The developers of RAMP did i...

4s-ferrugineone and 4s,5s-ferrugineol as pheromones of palm weevils were synthesized in 3 and 4 steps, respectively, starting from nonane-5-one employing samp-/ramp -hydrazone methodology. 5-nonanone is transformed to its corresponding ramp hydrazone by reaction with the enantiomerically pure hydrazine ramp. metalation with lithium diisopropylamide (lda) in ether to form azaenolate, followed by...

early triassic carbonate ramp sediments of the lower part of the elika formation are known as vermicular limestone. in the moro mountain, northwest iran, the vermicular limestone includes bioturbated dolomitic mudstone, bioclastic packstone and grainstone, algal calcirudite and intraclastic grainstone. these sediments accumulated in their lower part in open marine subtidal and shoal environment...

The overall objective of this research project is the development and evaluation of a flexible and cooperative management system within SME based production networks for the ramp-up process. Inter-organizational processes of six previous ramp ups were analyzed and documented in flow charts. Highlevel executives and domain-experts of the production nets developed in moderated focus-groups standa...

Wind energy is playing an important part for ecologically friendly power supply. Important aspects for the integration of wind power into the grid are sudden and large changes known as wind power ramp events. In this work, we treat the wind power ramp event detection problem as classification problem, which we solve with support vector machines. Wind power features from neighbored turbines are ...

Another goal of the program is to assess the effectiveness of “ramp-up,” a common mitigation protocol in which source levels are gradually increased prior to the onset of full-level transmissions. Ramp-up is thought to give nearby animals some time to move away before sonar transmissions reach maximum levels. However, it is unknown whether or not this protocol is actually effective. We have dev...
