The purpose of this study was to determine the influence of towing force magnitude on the kinematics of supramaximal sprinting. Ten high school and college-age track and field athletes (6 men, 4 women) ran 60-m maximal sprints under 5 different conditions: Nontowed, Tow A (2.0% body weight [BW]), Tow B (2.8% BW), Tow C (3.8% BW), and Tow D (4.7% BW). Three-dimensional kinematics of a 4-segment ...

We describe a new algorithm for the parametric identification problem for signal temporal logic (STL), stated as follows: Given a densetime real-valued signalw and a parameterized temporal logic formula φ, compute the subset of the parameter space that renders the formula satisfied by the signal. Unlike previous solutions, which were based on search in the parameter space or quantifier eliminat...

Fibrous tows used in continuous fibre-reinforced polymers (CFRPs) deform geometrically during the production of composite products. The cross-sectional geometry of the tow is influenced by the load-induced deformation mechanisms. A study of the effect of two commonly assumed geometrical tow shapes on an equivalent pressure distribution in a tow-on-a-pin spreading arrangement was performed. The ...

This paper introduces a tow stain detection method based on FPGA. To capture moving images through the line scanning CCD in real time and to design algorithms according to the different characteristics on the tow and stains.Then download it to FPGA development board running and debugging. Finally, displayimages on PC through the video conversion module.The experiments show that this design can ...

The Takeoff Weight (TOW) of an aircraft is an important aspect of aircraft performance, and impacts a large number of characteristics, ranging from the trajectory to the fuel burn of the flight. Due to its dependence on factors such as the passenger and cargo load factors as well as operating strategies, the TOW of a particular flight is generally not available to entities outside of the operat...

The civil aircraft engine business is complex in operation. Being an asset-heavy operating highly engineering systems, the optimized fleet life-cycle management essential yet challenging. aviation systems are known for critical operation conditions, high-standard reliability demands, and high cost both asset value through-life maintenance services. Civil engines typically require 3 to 4 costly ...
