Development of a ML Algorithm to Improve Radar Detection of Golf Balls Using MFCW Radar
… reliably detecting small targets, specifically golf balls, using Multi-Frequency Continuous-Wave (MFCW) radar in environments contaminated by significant noise and clutter. Although radar systems are effective at tracking targets, the performance of a radar system is heavily constrained by …

Investigating a causal model of anxiety in sport
… (A-state), was manipulated by assigning 72 golfers to either a low uncertainty group (LU), composed of unequal ability pairs, or a high uncertainty group (HU), consisting of equal ability pairs. In experiment two perceived importance, another hypothesised cause of A-state was manipulated by …

A System for Measuring the Lift and Drag Forces of a Spinning Golf Ball Held Fixed Within a Wind Tunnel
… to test the aerodynamic properties of a standard golf ball in a wind tunnel manufactured by ELD, Inc. model 406(B). The system consists of a rotating shaft, on which the golf ball is attached, connected to a two-axis force transducer. Additionally, an automated data acquisition system was built …

Influence of Annual Bluegrass on Putting Green Trueness and Control of Weedy Poa Species in Kentucky Bluegrass and Creeping Bentgrass Turf
… are among the most troublesome grass weeds on golf courses throughout the United States. Herbicides for selective control of these weeds in cool-season fairways are limited and ineffective. Methiozolin is a new isoxazoline herbicide that controls annual bluegrass on putting greens and shows …

A Prediction of the Acoustical Output of a Golf Driver Head Using Finite Elements
… to determine the acoustical properties of a golf ball and golf driver head impact. LS-DYNA® has a coupled finite element analysis (FEA) and boundary element method (BEM) solver that uses the integral form of Helmholtz’s acoustic wave equation to deliver predicted sound pressure levels at …

X-band Doppler simulator for sport projectile radars
… this dissertation was restricted to the sport of golf using continuous wave (CW) X-band Doppler radars. Raw data was measured by a Doppler radar to determine the velocity profiles of golf balls in flight. From these profiles, flight models were developed that could be simulated using a Doppler …
