The 3D animated simulator emulates an actual robot manipulator in a simulation space. The simulator is intended for use in teleoperation, where the graphical image represents the actual remote manipulator. The robot is viewed from a "camera position". The motion of the tip of the manipulator can be traced out in the simulation space as a continuous 3D line. The interface has the capability to graphically display the angles of the joint. It allows for a more accurate analysis of the simulated motion. The robot trajectory is defined by either a pre-calculated trajectory file or user specified end point and orientation.

When characterizing an extreme ultraviolet (EUV) lithographic optical system, visible light interferometry is limited to measuring wave front aberration caused by surface figure error while failing to measure wave front errors induced by the multilayer coatings. This necessitates the development of interferometric techniques at an EUV camera’s operational wavelength (at‐wavelength testing), which is typically around 13 nm. While a laser plasma source (LPS) is being developed as a lithography production source, it has generally been considered that only an undulator located at a synchrotron facility can provide the necessary laserlike point source brightness for EUV interferometry. Although an undulator‐based approach has been successfully demonstrated, it would be advantageous to test a camera in its operational configuration with an LPS. We are developing the latter approach by utilizing extended source size schemes to provide usable flux throughput. A slit mounted at the source plane can provide the necessary spatial coherence for lateral shearing interferometry. Initial results from an EUV lateral shear interferometer based on the Ronchi test are presented.

This paper presents an algorithm that allocates registers optimally for straight-line code running on a generic multi-issue computer. On such a machine, an optimal register allocation is one that minimizes the number of issue slots that the code requires. Optimal spill selection and load/store placement are used to minimize the number of additional issue slots needed, given a schedule for the non-memory reference instructions and a fixed number of available physical registers. The generic multi-issue machine model closely models the operation of vector and VLIW processors, and could be extended to model super-scalar processors. The algorithm uses dynamic programming to search the state space of feasible register allocations; implicit and explicit state pruning are used to make the problem tractable without sacrificing optimality. The optimal allocation produced by the algorithm for a substantial example is presented.
The audible noise produced by three‐phase, squirrel‐cage induction motors, is caused by the space harmonics of the flux‐density distribution in the air gap of the machine. When the motor is supplied by a frequency ...

A general formula relating the waveform at the output of a CMOS inverter to the waveform at its input is derived. The formula is applied to three cases: a step input, a ramp input, and an exponential input. A one-dimensional functional dependence of the inverter propagation delay and output slew rate on circuit parameters is derived and an inverter macromodel for timing analysis is suggested and experimentally verified.

A timing model for circular pipelines is presented and used to obtain the minimum cycle time in terms of circuit delays and clock skews. The model accounts for short- and long-path delays, the effects of clock skew, and the use of both latches and flip-flops as synchronizing elements. The formulation and implementation of algorithms to find the minimum cycle time for both single-phase and a restricted class of multi-phase clocks are described.< >
