Bipedal running can easily result in a fall due to poor availability of the ground reaction force at the boundary of the flight and support phases. We propose methods to decompose and synthesize a running gait pattern into vertical, horizontal and rotational components so that time-dependent ground friction limits are satisfied. We also extend previously proposed boundary condition, the diverge...

Three single-valued upper boundary functions for velocity, acceleration and deceleration of a wheeled mobile robot (WMR) are defined as closed mathematical forms over its entire spatial path. The limits deal with mechanical, kinematic and dynamic characteristics of the robot and with task and operating matters. These boundary functions can be computed making use of any robot model, as complex a...

The Acceleration Severity Index (ASI) is used to evaluate the potential for occupant risk in full-scale crash tests involving roadside safety hardware. Despite its widespread use across Europe, there is a lack of research relating this metric to occupant injury in real-world collisions. Recent installation of Event Data Recorders (EDRs) in a number of late model vehicles presents a different pe...

A new simple convergence acceleration method is proposed for a certain wide range class of convergent alternating series. The method has some common features with Smith’s and Ford’s modification of Levin’s and Weniger’s sequence transformations, but it leads to less computational and memory cost. The similarities and differences between all three methods are analyzed and some common theoretical...

1 SUMMARY In this project, we add a limited subset of staged functions to the Spatial hardware accelerator design language. This support includes implementation of language support for staged functions, analyses for optimizing performance and area, and generating synthesizable implementations of these staged functions. We evaluate these additions by comparing the runtime and area of a set of be...

We present a solid state accelerator concept utilizing particle acceleration along crystal channels by longitudinal electron plasma waves in a metal. Acceleration gradients of order 100 GV/cm are theoretically possible, but channeling radiation limits the maximum attainable energy to lo5 TeV for protons. Beam dechanneling due to multiple scattering is substantially reduced by the high accelerat...
