Figure 2 shows the vorticity cloud diagram, pressure cloud diagram, and streamlines for the aerostatic bearing with different orifice diameters by LES (orifice diameter is dn 0.28 0.2 0.12 0.04 mm). Figure 2a shows that a series of turbulent vortices are formed after the high-pressure air flows into the recess, and t...

not valid for fisheye cameras. The approximation of a fisheye lens model by a catadioptric one is usually possible, however, with limited accuracy only [335]. Conversely, the second model unifies both central catadioptric cameras and fisheye cameras under a general model also known as Taylor model. It was developed in ...

Dynamic mechanical analysis (DMA) measurements as a function of temperature, frequency, and dynamic force amplitude are used to perform a detailed study of the domain wall motion in LaAlO3. In previous DMA measurements Harrison et al. [Phys. Rev. B 69, 144101 (2004), 10.1103/PhysRevB.69.144101] found evidence for dynam...

When Woz told his dad (while in the first year of college) that one day he would have a desktop computer, his dad replied, “It costs as much as a house, son.” Woz argued that he’d “just live in an apartment then.” By 1975, Wozniak was already building his own computers and completed his first prototype in June of that ...

I usually begin my descent quite far out, reducing power to 20/1900 and descending at 500 to 800 fpm. Around three miles out, I turn off the fuel tank switcher, open the cowl flaps (in case it is necessary to go around) and deploy the airbrake (if it is not already out). At 100 kias or below I lower the landing gear an...

We decided that it was time to go back to the drawing board. In time periods, it was approximately a jump from the current era to the Iron Age. So, we designed appropriately. We designed a stainless steel hook, first making one out of prototyping wire. Then, we heated up the forge, adding plenty of coke, and set to wor...

One issue we have not yet addressed is how to define IK problems on a computer rather than mathematically. This is not so much of a problem with analytical methods --- you have spent hours deriving the solution and coding it up so you know exactly what the inputs and outputs need to be. But the strength of numerical me...

In this paper, we explore the two-point zeroth-order gradient estimator and identify the distribution of random perturbations that minimizes the estimator's asymptotic variance as the perturbation stepsize tends to zero. We formulate it as a constrained functional optimization problem over the space of perturbation dis...
