Mitigation of Gust Loads Through Pitching
… small α maintained when mitigating the gust via pitching, which results in a small leading edge vortex that advects near the wing surface. The results demonstrate the value of classical unsteady theory mitigating gusts. Therefore, a new formulae of this theory is re-derived for gust mitigation …

Youth Pitching Kinematics: Associations with Body Overweight Parameters
… from three separate collection sites examined pitching mechanics of 18 10- to 11-year-old pitchers, 11 14- to 16-year-old pitchers, and 104 16- to 18-year-old pitchers Linear regression analyses were performed to determine significant correlations between kinematic parameters and body mass …

The Development of a Novel Pitching Assessment Tool
… assess the posture of a pitcher during baseball pitching. Therefore, the purpose of this study was to develop an inexpensive tool which can allow for the rapid assessment of a pitcher’s posture at lead foot strike, and establish the inter- and intra- rater reliability of the tool. For this study, …

SmartPitch: Applied Machine Learning for Professional Baseball Pitching Strategy
… of baseball can be used to evaluate optimal pitching strategies that can exploit the tendencies of specific batters and leverage a pitcher’s arsenal of available actions to minimize offensive production. We will explore the application of well-known reinforcement learning algorithms to …

A study on the art and science of pitching new businesses
This study focuses on how entrepreneurs can optimize the venture capital procurement process by understanding the venture investment decision-making process. For new ventures, procuring capital is a notoriously difficult process. To succeed, an entrepreneurial team must overcome investor …

Unsteady incompressible viscous flow past stationary, pitching or oscillating airfoil leading edges
… a stationary parabola and of the flow past a pitching parabola compare well with the corresponding computational results for the NACA0012 airfoil. Navier-Stokes solutions for the pitching leading edge were obtained for chord Reynolds numbers up to half-a-million. The sequence of events leading …

The Storytelling Entrepreneur Has No Clothes: Risks and Rewards of Narrative Pitching
… shapes. This catalog illustrates isomorphism in pitching and the targets of narrative claims (e.g., the entrepreneur more than the market opportunity). While all Shark Tank entrepreneurs narrate answers to investors questions, only a third tell a story in the elevator pitch. Even when investors …

The Influence of Trailing Edge Shape and Kinematics on Bio-inspired Pitching Panels
… experimental and computational work on purely pitching panels has demonstrated that such planform shapes are not representative of propulsive optimality. Prior to the results of this dissertation, these counter-intuitive findings have primarily been observed for cases of rigid rectangular …

A Framework for Analysis of Softball Pitching, as Applied to Legal and Illegal Pitches
… the legal drag, legal leap, and illegal replant pitching techniques. By developing a pose estimation algorithm and Recurrent Neural Network (RNN) for use on videos of real collegiate pitchers, we aim to distinguish physiological differences between these types of pitches and use our RNN to …

The Effect Of Pitching With Underweight And Overweight Balls On Pitch Velocity In Collegiate Baseball Pitchers.
BACKGROUND: In an effort to improve overhand throw velocity in baseball pitchers, weighted implement training, which utilizes balls that are heavier or lighter than a competition ball, have been employed. Weighted ball programs have previously been used in baseball pitchers ranging from high school …

An experimental study of the relationship between forces and moments and vortex breakdown on a pitching delta wing
… motions were produced by sinusoidally pitching the model over a range of reduced frequencies. Ramp motions were obtained using an initial sinusoidal increase in angle of attack and hold. Aerodynamic forces and moments were obtained from a six-component internal strain-gauge balance. In …
