“Walking extradurals” in labour: a step forward?

Dynamic walking: a step forward?

After a long time as a junior partner in robotics, walking has seen an explosion in interest and achievements in the last 15 years as computational power unimaginable until recently has been brought to bear on its problems. At the same time we have seen advances in other related fields: non-linear dynamics has helped us understand and model the robotic systems that we are studying; zoology has ...

One step forward

[A step forward].

Nos gustaría comenzar esta nueva etapa agradeciendo a Elsevier y al anterior equipo editorial su esfuerzo, su constancia y su contribución al desarrollo de la Enfermería desde que comenzaron su andadura en el año 2004. Sin duda, Enfermería Clínica ha brindando a los enfermeros y enfermeras la posibilidad de colaborar en un objetivo común: el avance de la profesión para poder ofrecer nuestra mej...

An Enhanced Flux Treatment in Solving Incompressible Flow in a Forward-Facing Step

The aim of this paper is to give a detailed effect of several parameters such as step height, Reynolds number, contraction ratio, and temperature difference between the entrance and solid boundaries, of a forward-facing step. An accurate length of separation and reattachment zones are achieved. A finite-volume method (FVM) has been developed to study incompressible flow in a forward-facing step...

Effect of Step Length and Step Period on Walking Speed and Energy Consumption: a Parameter Study

Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...
