Three distances (1.2, 3.0 and 7.6 m) and 4 methods (complete diagonal swing, impinger, top diagonal swing and vertical swing) were compared in analyzing the droplet spectra of electrically generated ULV aerosol clouds. There were no significant differences among the 4 methods and no interaction between method and distance. However, when compared over distance, the percent variability indicated ...

SWING ist der Anfrageund Suchdienst des Landesinformationssystems MV-Info, das die Internet-Informationsangebote Mecklenburg-Vorpommerns integriert und klassifiziert. SWING umfaßt neben klassischen Suchtechniken auch diverse neue Merkmale wie Konsistenzchecks, Profildienste und insbesondere das Ausnutzen von Strukturen in Informationen, die aus Datenbanken stammen. In diesem Beitrag wird ein Üb...

Many children with cerebral palsy walk with diminished knee extension during terminal swing, at speeds much slower than unimpaired children. Treatment of these gait abnormalities is challenging because the factors that extend the knee during normal walking, over a range of speeds, are not well understood. This study analyzed a series of three-dimensional, muscle-driven dynamic simulations to de...

Stability is an important concern during human walking and can limit mobility in clinical populations. Mediolateral stability can be efficiently controlled through appropriate foot placement, although the underlying neuromechanical strategy is unclear. We hypothesized that humans control mediolateral foot placement through swing leg muscle activity, basing this control on the mechanical state o...

Clinical studies of hemiparetic walking have shown pre-swing abnormalities in the paretic leg suggesting that paretic muscle contributions to important biomechanical walking subtasks are different than those of non-disabled individuals. Three-dimensional forward dynamics simulations of two representative hemiparetic subjects with different levels of walking function classified by self-selected ...

A field study was conducted to measure the effect of a bat’s weight and mass moment of inertia (MOI) on the swing speed. The study involved 16 amateur slow-pitch softball players of two skill levels and two groups of bats. One bat group had a constant MOI, but varying weight, while the other group had constant weight, but varying MOI. Players were assigned to either the constant MOI or constant...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

Using simple running models, researchers have argued that swing-leg retraction can improve running robot performance. In this paper, we investigate whether this holds for a more realistic simulation model validated against a physical running robot. We find that swing-leg retraction can improve stability and disturbance rejection. Alternatively, swing-leg retraction can simultaneously reduce tou...

This paper describes the application of the first fully wireless network of inertial sensors for full-body 3-D motion capture – the Orient-2 system, to real-time on-body analysis of the golf swing. The golfer-club system is modelled as a double pendulum. The factors which affect the efficiency of the golf swing are outlined, such as the length of the back swing, the wrist-cock angle, swing plan...
