Resistive economy as the ability of societies in adaptability and versatility in the face of shocks is viewed based on the institutional literature as an “Adaptive Efficiency”- that the amount of the effectiveness depends on the flexibility of the institutional matrix of the society. The power structure is one of the most important factors in the institutional structure of societies, and i...

The purpose of this study was to develop a simple approach to evaluate resistive frictional forces acting on manual wheelchairs (MWCs) during straight and turning maneuvers. Using a dummy-occupied MWC, decelerations were measured via axle-mounted encoders during a coast-down protocol that included straight trajectories and fixed-wheel turns. Eight coast-down trials were conducted to test repeat...

Resistive memory has attracted a great deal of attention as an alternative to contemporary flash memory. Here we demonstrate an interesting phenomenon that multimode resistive switching, i.e. threshold-like, self-rectifying and ordinary bipolar switching, can be observed in one self-assembled single-crystalline ZnO nanoisland with base diameter and height ranging around 30 and 40 nm on Si at di...

In the process of automating an earthmoving machine, we have developed a model of soil-tool interaction that predicts resistive forces experienced at the tool during digging. The predicted forces can be used to model the closed loop behavior of a controller that servoes the joints of the excavator so as to fill the bucket. In this paper, we extend the state of the art in two ways. First, we pre...

We report on the use of scanning force microscopy as a versatile tool for the electrical characterization of nanoscale memristors fabricated on ultrathin La(0.7)Sr(0.3)MnO(3) (LSMO) films. Combining conventional conductive imaging and nanoscale lithography, reversible switching between low-resistive (ON) and high-resistive (OFF) states was locally achieved by applying voltages within the range ...

Huub M. Toussaint and Martin Truijens Peak performances in sport require the full deployment of all powers an athlete possesses. How factors like mechanical power output, technique, and drag, each in itself but also in concert with each other, determine swimming performance is the subject of inquiry in this case study. At constant speed, a swimmer is subjected to the resistive forces of water, ...

Resistive switching properties of a self-compliance resistive random access memory device in cross-point architecture with a simple stack structure of Ir/TaOx/W have been investigated. A transmission electron microscope and atomic force microscope were used to observe the film properties and morphology of the stack. The device has shown excellent switching cycle uniformity with a small operatio...

Force-feedback mechanisms have been designed to simplify and enhance the humanvehicle interface. The increase in secondary controls within vehicle cockpits has created a desire for a simpler, more efficient human-vehicle interface. By consolidating various controls into a single, haptic feedback control device, information can be transmitted to the operator, without requiring the driver’s visua...
