Stepping On is a community-based intervention that has been shown in a randomized controlled trial to reduce fall risk. The Wisconsin Institute for Healthy Aging adapted Stepping On for use in the United States and developed a training infrastructure to enable dissemination. The purpose of this study is to: (1) describe the personal characteristics of Stepping On participants; (2) quantify part...

Problem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless chann...

Partial body weight support (PBWS) during locomotion on a treadmill has been used to improve gait for persons with incomplete spinal cord injury (SCI). Combined therapy that uses functional neuromuscular stimulation (FNS) to assist in generating locomotor movements may lead to improvements in PBWS locomotor training. The effectiveness of this combined approach may strongly depend on the ability...

This paper proposes the implementation of a fuzzy based robust sliding model control design to obtain voltage regulation in a boost converter with high dc gain. The proposed controller has an inner loop based on slidingmode control whose sliding surface is defined for the input inductor current. The current reference value of the sliding surface is modified by a fuzzy logic controller in an out...

This paper presents an integration of laser-based perception, footstep planning, and walking control of a humanoid robot for navigation on previously unknown rough terrain. Perception system that obtains the shape of surrounding environment in a few centimeters accuracy is realized by using scanning type laser range sensor as input. A footstep planner decides the sequence of stepping positions ...

In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependant plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependant plasti...
