A 1.6 GS/s Track and Hold circuit that produces 16 interleaving, 100 MS/s voltage buffered output signals is presented. The achieved SFDR for a 950 MHz full scale input signal is 50 dB. Phase alignment is 0.4 ps RMS and aperture uncertainty is 1 ps RMS. The chip includes two Analog to Digital Converters and a Switching Matrix to accommodate measurement of all sampled output signals and their ti...

For an abstract programming language with action reenement both an operational and a denotational semantics are given. The operational semantics is based on an SOS-style transition system speciication involving syntactical reenement sequences. The denotational semantics is an interleaving model which uses semantical reenementènvironments'. It identiies those statements which are equal under all...

Many formalisms use interleaving to model concurrency. To describe some system behaviours appropriately, we need to limit interleaving. For example, in a component-based system, we might wish to limit interleaving to force the inputs to a method to arrive together in order. In Web services, the arrival of XML messages consisting of multiple simple parts should not be interleaved with the behavi...

In this work, we explore transport layer protocol design for an optical flow-switched network. The objective of the protocol design is to guarantee the reliable delivery of data files over an all-optical endto-end flow-switched network which is modeled as a burst-error channel. We observe that Transport Control Protocol (TCP) is not best suited for Optical Flow-Switching (OFS). Specifically, fl...

Most coding schemes used in today’s communication systems are designed for memoryless channels. These codes break down when they are transmitted over channels with memory, which is in fact what real-world channels look like since errors often occur in bursts. Therefore, these systems employ interleaving to spread the errors so that the channel looks more or less memoryless (for the decoder) at ...

Abstract: We propose a block image compressive sensing algorithm based on interleaving extraction in Contourlet domain to improve the performance of image sparse representation and quality of reconstructed images. First, we propose the interleaving extraction scheme and partition an image into several sub-images using interleaving extraction. Second, we represent the sub-images in Contourlet do...

We introduce two independent approaches for phase noise suppression. The dominant effects, responsible for the degradation of an OFDM system performance, if phase noise is present, are identified. We found out, that the system performance is strongly influenced by certain phase noise realizations, which cause burst errors, resulting in the performance error floor. Consideration of the system ca...

The aim of the paper is to introduce the notion of a transformation unit together with its interleaving semantics and to study it as a means of constructing large graph transformation systems from small ones in a structured and systematic way. A transformation unit comprises a set of rules, descriptions of initial and terminal graphs, and a control condition. Moreover, it may import other trans...

Kornell and Bjork (Psychological science 19:585-592, 2008) found that interleaving exemplars of different categories enhanced inductive learning of the concepts based on those exemplars. They hypothesized that the benefit of mixing exemplars from different categories is that doing so highlights differences between the categories. Kang and Pashler (Applied cognitive psychology 26:97-103, 2012) o...
