In the recent decades an increasing number of research papers and books have dealt with
time-delay systems in applied sciences. Time delay emerged first in population dynamics …

Why can we balance a yardstick but not a pencil on the tip of our finger? As with other
physical systems, human motor control has constraints, referred to as bandwidth, which …

An empirical nonlinear, frequency-dependant, spring-mass system is conjectured for
modelling human rhythmic jumping. This model is vital for correctly estimating human …

The process of pursuit and escape underlies many biological phenomena ranging from
predator–prey interactions, combat and sporting activities. Time delays, τ, arise as a …

A model describing rider control while steering and stabilizing a bicycle has been
developed. Experimental data were obtained from riding a bicycle on a narrow treadmill …

The development of strategies to minimize the risk of falling in the elderly represents a major
challenge for aging in industrialized societies. The corrective movements made by humans …

A complex object is a system with internal degrees of freedom, such as a cup of hot coffee
hand-held by a human in walking. In spite of the natural ability of humans to handle complex …

Basic single-degree-of-freedom mechanical models of force control are presented to
achieve desired contact forces between actuators and objects. Nonlinear governing …

The effect of reaction delay, temporal sampling, sensory quantization, and control torque
saturation is investigated numerically for a single-degree-of-freedom model of postural sway …
