A Theoretical Investigation of the Maximum-lift Coefficient

The Journal of the Royal Aeronautical Society, 1935
The problem of the maximum lift of airfoils has concerned the authors greatly since there were first discovered in the spring of 1932 serious discrepancies in this characteristic between results obtained in the wind tunnel of the Guggenheim Aeronautics Laboratory at the California Institute of Technology (GALCIT) and those reported from certain other ...

Invertible deinterlacing with variable coefficients and its lifting implementation

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003
Invertible deinterlacing with variable coefficients is proposed to suppress comb-tooth artifacts caused by field interleaving of interlaced scanning video. A vertical highpass filter is applied to detect moving artifacts around boundaries of moving objects.

Constant Lift Coefficient Turns

Journal of Aircraft, 2005
Lateral displacement in a U-turn may become a problem when aircraft position has to be accurately maintained, but the excess thrust is inadequate to sustain level turn of sufficiently small radius. It seems plausible that lateral displacement in a U-turn can be diminished at the expense of mechanical energy: This trade of energy is the subject matter ...

Predicting Maximum Lift Coefficient for Twisted Wings Using Lifting-Line Theory

45th AIAA Aerospace Sciences Meeting and Exhibit, 2007
A method is presented that allows one to predict the maximum lift coefficient for a wing from knowledge of wing geometry and maximum airfoil section lift coefficient. The method applies to wings of arbitrary planform and includes the effects of twist and sweep.

Congruences for fourier coefficients of lifted siegel modular forms I: Eisenstein lifts

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2005
The author asks the following question: Does a lifting of modular forms preserve congruences for Fourier coefficients? In this paper he gives an affirmative answer in case of the Eisenstein lift. Let \(S^r_k\) denote the space of cusp forms of even weight \(k> 0\) with respect to the modular group \(\Gamma_r\) of degree \(r\).

Congruences for Fourier coefficients of lifted Siegel modular forms II: The Ikeda lifts

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 2007
In part I [Abh. Math. Semin. Univ. Hamb. 75, 97--120 (2005; Zbl 1088.11032)], the author studied whether a congruence for Fourier coefficients of Siegel modular forms is preserved under Eisenstein lifts. Now he proves criteria for the preservation of such congruences under two types of lifts [\textit{T. Ikeda}, Ann. Math. (2) 154, No. 3, 641--681 (2001;
