A review of the physical characteristics of sulfur-containing aerosols, with respect to size distribution of the physical distribution, sulfur distributions, distribution modal characteristics, nuclei formation rates, aerosol growth characteristics, and in situ measurement, has been made. Physical size distributions can be characterized well by a trimodal model consisting of three additive log-...

We have developed a compact wireless modular sensor architecture, which contains a number of circuit boards (panes), currently used in an application for on-shoe gait analysis. Each pane instantiates a major function – e.g. inertial sensing, tactile sensing or data collection and transmission. As opposed to similar architectures, this system treats the sensor panes as discrete design objects th...

This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were col...

This study aims to investigate the effects of shoe traction and obstacle height on lower extremity relative phase dynamics (analysis of intralimb coordination) during walking to better understand the mechanisms employed to avoid slippage following obstacle clearance. Ten participants walked at a self-selected pace during eight conditions: four obstacle heights (0%, 10%, 20%, and 40% of limb len...

This study attempted to evaluate the influence of using an unstable shoe in muscle recruitment strategies and center of pressure (CoP) displacement after the application of an external perturbation. Fourteen healthy female subjects participated in this study. The electromyographic activity of medial gastrocnemius, tibialis anterior, rectus femoris, biceps femoris, rectus abdominis and erector s...

The present investigation was prompted by the Northamptonshire Miniature MassRadiography Survey of 1945a-46. One of the findings of this survey, as presented by Smith (1947), was a significantly higher proportion of newly-discovered cases of active pulmonary tuberculosis* among boot and shoe factory workers than among workers in other trades. In July, 1947, the manufacturers asked for an invest...

Advances in image acquisition and storage technology have led to tremendous growth in very large and detailed image databases. These images, once analysed, can reveal useful information to our uses. The focus for image mining in this article is clustering of shoe prints. This study leads to the work in forensic data mining. In this article, we cluster selected shoe prints using k-means and expe...

This letter evaluates the capabilities of a soft robotic pneumatic actuator derived from terrain display haptic device, “Smart Shoe.” The bladder design Smart Shoe is upgraded to include pressure supply and greater output flow capabilities. Forcing characteristics are identified incorporated as feedforward terms in sliding-mode tracking controller provide impedance control. A bench top setup cr...
