Aerodynamics in DFVLR-AVA

Aerodynamics in Cardiac CT.

I t seems not long ago that invasive coronary angiography was considered as the undisputed diagnostic standard and management determining test for patients with ischemic heart disease. Registry data have shown that reliance on noninvasive testing for myocardial ischemia, positioned as a gatekeeper to restrict referral to the catheterization laboratory, is far from optimal in clinical practice. ...

Surprises in cycling aerodynamics

Federal Lab. for Materials Testing and Research (Empa) Dübendorf Switzerland l 5 Bakala Academy Athletic Performance Center Univ. of Leuven Heverlee, Belgium Surprises in cycling aerodynamics T he greatest potential for improvement in cycling speed is aerodynamic” [1]. At racing speeds (about 54 km/h or 15 m/s in time trails), the aerodynamic resistance or drag is about 90% of the total resista...

Ava: From Data to Insights Through Conversations

Enterprises increasingly employ a wide array of tools and processes to make data-driven decisions. However, there are large inefficiencies in the enterprise-wide workflow that stem from the fact that business workflows are expressed in natural language but the actual computational workflow has to be manually translated into computational programs. In this paper, we present an initial approach t...

Aerodynamics of [ r ] in tonogenesis

Explanation and discovery in aerodynamics

The purpose of this paper is to discuss and clarify the explanations commonly cited for the aerodynamic lift generated by a wing, and to then analyse, as a case study of engineering discovery, the aerodynamic revolutions which have taken place within Formula 1 in the past 40 years. The paper begins with an introduction that provides a succinct summary of the mathematics of fluid mechanics.
