Human body detection is very important in the research of automotive safety technology. The extraction and analysis human micro-motion based on frequency-modulated continuous wave (FMCW) radar gradually receiving attention. Aimed at modulation effect FMCW radar, a running model proposed to study characteristics. According scattering characteristics rigid bodies, analytical expression echoes est...

BACKGROUND The aims of the study were to examine the (a) participation, (b) difference in running times between the sexes, and (c) age-related decline in the running times of ultramarathoner women and men competing in the Swiss Alpine Marathon from 1998 to 2011. METHODS The ultramarathoners competing in the Swiss Alpine Marathon were analyzed in terms of participation, difference in running t...

A technique to study the dynamics of solving of a research task is suggested. The research task was based on specially developed software RightWrong Responder (RWR), with the participants having to reveal the response logic of the program. The participants interacted with the program in the form of a semi-binary dialogue, which implies the feedback responses of only two kinds “right” or “wrong”...

This study investigated changes in lower-extremity joint work and power during the swing phase in a maximal accelerated sprinting. Twelve male sprinters performed 60 m maximal sprints while motion data was recorded. Lower-extremity joint work and power during the swing phase of each stride for both legs were calculated. Positive hip and negative knee work (≈4.3 and ≈-2.9 J kg-1) and mean power ...

Human-like running is a natural dynamic mode of a simple mechanical biped. Such a machine consists of two telescoping legs with linear spriags, connected by a hip joint with a torsional spring. It will run passively; i.e. no pattern of forcing is required to generate the gait. With careful design its energy consumption can approach zero, but in any case the passive cycle can be "pumped" by vari...

Despite increased interest in ultra-endurance events, little research has examined ultra-triathlon performance. The aims of this study were: (i) to compare swimming, cycling, running, and overall performances in three ultra-distance triathlons, double Ironman distance triathlon (2IMT) (7.6 km swimming, 360 km cycling, and 84.4 km running), triple Ironman distance triathlon (3IMT) (11.4 km, 540 ...

Melatonin and wheel-running rhythmicity and the effects of acute and chronic light pulses on these rhythms were studied in Clock(Delta19) mutant mice selectively bred to synthesize melatonin. Homozygous melatonin-proficient Clock(Delta19) mutant mice (Clock(Delta19/Delta19)-MEL) produced melatonin rhythmically, with peak production 2 h later than the wild-type controls (i.e., just before lights...

Most business applications rely on the notion of long running transaction as a fundamental building block. This paper presents a calculus for modelling long running transactions within the framework of the π-calculus, with support for compensation as a recovery mechanism. The underlying model of this calculus is the asynchronous polyadic π-calculus, with transaction scopes and dynamic installat...

This study investigated kinematics of human accelerated sprinting through 50 m and examined whether there is transition and changes in acceleration strategies during the entire acceleration phase. Twelve male sprinters performed a 60-m sprint, during which step-to-step kinematics were captured using 60 infrared cameras. To detect the transition during the acceleration phase, the mean height of ...
