OBJECTIVE The purpose of this study was to investigate the apparent mass of the sitting human body and to compare it with current experimental data and the ISO 5982 standard impedance model. METHOD The apparent mass of the seated human body in the vertical direction was measured. Twelve male subjects were exposed to random whole-body vibration of frequency range (1-20 Hz), with a vibration ex...

Abstract Online media has an advantage over other conventional media, such as television and radio, namely interactivity. This interactivity process causes two-way communication between users on social media. Although biodynamic techniques have long been discovered developed, their application is still not developed in Indonesia. study aims to discover how innovation spread through the of Whats...

Helmet-mounted systems (HMS), such as night vision goggles and helmet-mounted displays, are designed to enhance pilot performance. Using HMS, however, may also affect pilot safety by increasing the potential for neck injury during ejection due to the increase in dynamic forces generated in the cervical spine as a result of the change in helmet inertial properties. Pilot bracing techniques may a...

Human graviceptors, located in the trunk by Mittelstaedt, probably transduce acceleration by abdominal viscera motion. As demonstrated previously in biodynamic vibration and impact tolerance research, the thoraco-abdominal viscera exhibit a resonance at 4 to 6 Hz. Behavioral observations and mechanical models of otolith graviceptor response indicate a phase shift, increasing with frequency betw...

Alternative farming methods must be deployed to mitigate the detrimental impacts of intensive agriculture on climate, biodiversity, and ecosystem services. Organic biodynamic are environmental-friendly practices that progressively replace conventional agriculture. While potential biodiversity benefits organic vs . have been studied repeatedly, effects remain ill-understood. We investigated thes...

The biomechanical responses of the driver-truck system in a dynamic environment have become significant concern design and control trucks. When evaluating riding comfort seat-cab system, it is necessary to predict driver’s different parts directions. However, there no reliable model method for effectively predicting response characteristics driver-seat-cab system. Aiming at such problem, firstl...

To enhance believability of virtual agents, this paper presents an agent-based modelling approach for decision making, which integrates rational reasoning based on means-end analysis with personal psychological and biological aspects. The agent model developed is a combination of a BDI-model and a utility-based decision model in the context of specific desires and beliefs. The approach is illus...

The capability of a computational system to deal with unexpected, changing situations and limited perception of the environment is becoming more a more relevant, in oder to make systems flexible and more reliable. Multi-agent Systems offer a computing paradigm where properties such as autonomy, adaptability or flexibility are basic in the construction of agent-based solutions. However most of c...
