This paper presents an analysis of a golf swing to detect improper motion in the early phase of the swing. Led by the desire to achieve a consistent shot outcome, a particular golfer would (in multiple trials) prefer to perform completely identical golf swings. In reality, some deviations from the desired motion are always present due to the comprehensive nature of the swing motion. Swing motio...

The evaluation of matching applications is becoming a major issue in the semantic web and it requires a suitable methodological approach as well as appropriate benchmarks. In particular, in order to evaluate a matching application under different experimental conditions, it is crucial to provide a test dataset characterized by a controlled variety of different heterogeneities among data that ra...

Inadequate peak knee extension during the swing phase of gait is a major deficit in individuals with spastic cerebral palsy (CP). The biomechanical mechanisms responsible for knee extension have not been thoroughly examined in CP. The purpose of this study was to assess the contributions of joint moments and gravity to knee extension acceleration during swing in children with spastic hemiplegic...

Swing options are the main type of volumetric contracts in commodity markets. A swing contract gives the holder the right (but not the obligation) to adjust volume of received commodity at her discretion. Unlike paper assets, trading in physical commodities often takes place over time and therefore involves volume as a second key state variable. Often consumption rates of the commodity are unpr...

This study analyzed the biomechanical and physiological effects of the arm swing in roller ski skating, and compared leg-skating (i.e. ski skating without poles) using a pronounced arm swing (SWING) with leg-skating using locked arms (LOCKED). Sixteen elite male cross-country skiers performed submaximal stages at 10, 15 and 20kmh(-1) on a 2% inclined treadmill in the two techniques. SWING demon...

Swing is a musical performance technique, whose magnitude is indicated by the swing ratio. This study examines the effects of swing on music-listening appreciation. In Experiment 1, 21 participants were presented with synthesized performances with three swing ratios, and were asked to rate their impressions using the semantic differential method. The results show that there exists a certain rel...

In this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. It provides both robust tracking and load swing suppression. Inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. The crane nonlinearities are then tr...

Measurements are presented of the speed at which six different rods could be swung by four male students. Three of the rods had the same mass but their swing-weight (i.e. moment of inertia) differed by large factors. The other three rods had the same swing-weight but different masses. Our primary objective was to quantify the effects of mass and swing-weight on swing speed. The result has a dir...

The relations among swing, stance and step durations for the fore and hind limbs were investigated. Registration of the swing and stance phases was performed by the opening and closing of an electrical circuit as the cat moved along the conductive pathway. In the walking animal, longer swing and shorter stance durations for hind limbs, in comparison with the fore limbs, were observed. However, ...

When walking (at moderate or fast speeds) or running, humans apply a burst hip torque to start leg swing and then again, at the end of the swing phase, to brake and reverse motion of their swing leg prior to heel-strike. The resulting rearward rotation of the swing leg, so called swingleg retraction, is also observed in animal gaits. Why is this retraction a common feature of many walking and r...
