We measured resolution at 10 degrees in the inferior temporal retina using horizontal and vertical gratings of different contrasts which modulated in time at temporal frequencies from 0 to 40 Hz. Since peripheral grating resolution is directly related to the sampling density of retinal ganglion cells this allowed us to observe changes in responding ganglion cell density as the stimulus properti...

Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to heir thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed periodic temperature changes up to 00 K with a frequency of 0.05 Hz. However, a broad temperature gradient of 80 K developed inside the reactor. A...

Flow visualization with high-speed video of evaporating water films falling over flat horizontal tubes, representative of the external surfaces of microchannel tubes, is presented. Experiments were conducted with 1.4 mm thick and 27 mm tall tubes over a film Reynolds number range of 23 < Re < 126. In addition to a qualitative description of the flow mechanisms, this work quantifies key droplet ...

We are interested in the stability and control of dynamic legged climbing. Motivated by the success of the lateral leg spring (LLS) and spring-loaded inverted pendulum (SLIP) templates for transverse and sagittal plane running on horizontal surfaces, our effort is to similarly approximate the analytically intractable dynamics of a full dimensional system through planar models, and develop simpl...

SUMMARY. In a parallel line assay, there are three treatment contrasts of major importance. Block designs allowing the estimability of all the three contrasts free from block effects, called L-designs, necessarily have the block sizes even. For odd block sizes, we provide here a class of highly efficient designs, called nearly L-designs. These nearly L-designs have been constructed by establish...
