The use of a phase plate in electron microscopy has shown renewed interest, triggered by a publication on this topic in 2001 by Danev and Nagayama [1]. This interest can be understood from the fact that many samples that are studied in TEM are weak phase objects. The use of a phase plate is the obvious method of choice to convert otherwise invisible phase modulations into visible amplitude modu...

—A burst-mode clock recovery circuit with a novel dual bit-rate structure is presented. It utilizes two gated-oscillators to align clock with data edges and can operate in half-rate clocking mode, doubling data throughput, as well as in full-rate clocking mode. The gated-oscillator reset-phase control scheme causes the starting phase of gated-oscillators to alternate repeatedly between 0° and 1...

A burst-mode clock recovery circuit with a novel dual-mode structure is presented. It utilizes two gated-oscillators to align recovered clock edges to data. It can operate in double data-rate mode in which both rising and falling edges of recovered clock are used. To enable this, gated-oscillator reset-phase control scheme is introduced to switch the starting phase of gated-oscillator dynamical...

The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...

This paper provides an approximate analytic solution method for evaluating the performance of concurrency control protocols developed for real-time database systems (RTDBSs). Transactions processed in a RTDBS are associated with timing constraints typically in the form of deadlines. The primary consideration in developing a RTDBS concurrency control protocol is the fact that satisfaction of the...

A method is proposed to determine the phase-volume fractions in tomographic representations of two-phase systems. The method is applicable in cases where no independent mean values for the phase-characteristic property (a) are available, such as in standard X-ray computed tomography (CT) using a polychromatic source. The proposed procedure is based on ®tting a sum of three parametric expression...
