Fig. 30.5. Nondimensional shoreline evolution for initial rectangular platform. Note that the initial and subsequent planforms are symmetric about x = 0 and the solutions for a < 0 are not shown.

The Semilive Skid. The semilive skid is a rectangular platform or box having two wheels on one end and two fixed supports on the other. The end having the fixed supports is also fitted with a heavy pickup pin to which a two-wheeled jack is attached. The jack and handle are used as the lifting device and tiller, allowing the skid to be maneuvered by the operator. 

Regardless of IBM s interest, Microsoft continued on its own with its development of the GUI— which it named Windows after its rectangular work areas— and released the first version to the market in 1985. Apple filed a lawsuit soon after, claiming that the Microsoft GUI had been built using Apple technology, but the suit was dismissed. Apple s Macintosh and Microsoft s DOS-with-Win-dows combo have both continued to evolve, but until a recent deal between Apple and Microsoft, tensions have always been high. Mac and PC users, of course, still remain adamantly chauvinistic about their respective platforms. 

The windows are 3/4 inch x 3/4 inch quartz. A triangular magnetic stir bar at the bottom of the cell stirs the lower phase in the cell. A rectangular stainless steel wire mesh "flapper on a shaft set into the magnetic stir bar stirs the upper phase. The solid sample rests on a stainless steel wire mesh platform at the level of the side window of the view cell. 

Printed circuits are generally planar objects. Usually square or rectangular, they are essentially flat platforms supporting interconnect networks on which are mounted a mixture of electronics or electrical components. These components may be leaded devices (either radial or axial) passing through the board, or mounted components on the board surface. The circuit board acts as a "customizing" device, linking standard or special components to create circuit functionality. (2)... 

Platform Cuvettes. The concept of platform atomization was first described by L vov in 1978. A platform is a thin rectangular piece of pyrolytic graphite. The platform is positioned within a conventional graphite cuvette as shown in Figure 47. Samples are injected on the platform. Contact... 

Platform Atomization. A platform is a thin, rectangular shaped piece of graphite (normally prepared from pyrolytic graphite), which is mounted inside the conventional graphite tube. The platform is positioned in the centre of the cuvette. The platform is heated by cuvette wall radiation since it fits into a slot in the wall of the graphite cuvette and therefore does not come into direct contact with the hot centre portion of the tube. 

One can envision three types of perturbation an infinitesimally narrow light pulse (a Dirac or S-functional), a rectangular pulse (characteristic of chopped or interrupted irradiation), or periodic (usually sinusoidal) excitation. All three types of excitation and the corresponding responses have been treated on a common platform using the Laplace transform approach and transfer functions [170]. These perturbations refer to the temporal behavior adopted for the excitation light. However, classical AC impedance spectroscopy methods employing periodic potential excitation can be combined with steady state irradiation (the so-called PEIS experiment). In the extreme case, both the light intensity and potential can be modulated (at different frequencies) and the (nonlinear) response can be measured at sum and difference frequencies. The response parameters measured in all these cases are many but include... 

During the past ten years increasing numbers of pultruded GRP portal frame structures have been erected. Most of the rectangular portal frames are small (column height typically 1.5-2 m and beam span typically 2-3 m) and are used to support raised platforms or walkways. A few, much larger, pitched roof portal frames have also been erected. Little has appeared in the literature on any proof load or other tests carried out on these frames. 

Figure 6-17. Coaxial electrical cable s PS insulation buttons are here being injection molded, using a cold runner system, but it could also use a hot runner one. In this continuous production process, the injection-molding machine (IMM) is on a platform that moves in a rectangular pattern to permit the platens to open and move away from the buttons, as well as to move at the speed of the six-cable copper wire line when the mold is closed and the IMM is injecting the PS. Copper wires are started out with large diameters and are pulled through reduction squeeze rolls to their final thin diameter prior to entering the IMM. The wire-reduction line is to the left of the IMM, with the wire pullers to its left. Automatic devices remove the runners on-line just after they leave the IMM and the additional cooling station fiiat is shown in this view.
