In this paper, we consider the problem of precise step length control on underactuated hopping robots, integrating analytical SLIP-based trajectories on a hardware inspired hopper model that includes series-elastic actuation (SEA), leg mass and inertia. Additionally, in the model considered the body center of mass (CoM) is not collocated with the hip joint, and must be stabilized for successful...

For a microchamber filled with a binary electrolyte and containing a flat unbiased center electrode at one wall, we employ three numerical models to study the strength of the resulting induced-charge electro-osmotic (ICEO) flow rolls: (i) a full nonlinear continuum model resolving the double layer, (ii) a linear slip-velocity model not resolving the double layer and without tangential charge tr...

PURPOSE Angiogenesis plays a critical role in breast cancer progression and metastasis. Early detection could be important for improved treatment. Therefore, Dynamic contrast-enhanced (DCE) breast examinations have become a standard tool for the diagnosis of breast cancer diseases [1,2]. Due to recent concerns about Nephrogenic Systemic Fibrosis (NSF), there is an increasing need to use nonenha...

stabilization of earth slopes with various proposed methods is one of the important concerns of geotechnical engineering. in this practice, despite numerous developments, design conservativeness and high costs of stabilization are the issues yet to be addressed. this paper not only deals with pile location optimization but also studies the effects of the pile length by using line segments slip ...

this paper studied the mathematical method of flow with regard to two-phase boundary layer that created over the iced surface. based on experimental results, skin drag over the iced surface compared with this force that compute with slip condition. based on this results, for iced surface blasius equation solving at non-slip condition, can replace with solving the blasius equation with slip cond...

There is an obvious need for a technique whereby the medium surrounding an organism under microscopy can be altered without displacing the organism from the field. For example, we are interested in observing the same organisms before, during, and after exposure to various agents. Our general solution is to confine the organisms within a microchamber separated from the well of a well-slide by a ...

[1] Among the most fascinating, recent discoveries in seismology are the phenomena of dynamically triggered fault slip, including earthquakes, tremor, slow and silent slip—during which little seismic energy is radiated—and low frequency earthquakes. Dynamic triggering refers to the initiation of fault slip by a transient deformation perturbation, most often in the form of passing seismic waves....

We herein report the results of some numerical simulations of complex earthquake cycles using a threedegree-of-freedom spring-block model with a rateand statedependent friction law. The model consists of three blocks on a conveyor belt that is moving at a steady rate. Observed complex slip behaviour in the simulations is classified into five slip patterns, and for each of these the parameter de...
