BACKGROUND Continuous viewing of ambiguous patterns is characterized by wavering perception that alternates between two or more equally valid visual solutions. However, when such patterns are viewed intermittently, either by repetitive presentation or by periodic closing of the eyes, perception can become locked or "frozen" in one configuration for several minutes at a time. One aspect of this ...

A laminated composite was produced using a thermoplastic prepreg by inserting an interleaved film with the same type of matrix as the prepreg during the lay-up process to improve the low interlaminar properties, which is a known weakness of laminated composites. Carbon fiber fabric (CFF) and polypropylene (PP) were used to manufacture the thermoplastic prepregs. Eight prepregs were used to prod...

PURPOSE Modification of a clinical MRI scanner to enable simultaneous or rapid interleaved acquisition of signals from two different nuclei. METHODS A device was developed to modify the local oscillator signal fed to the receive channel(s) of an MRI console. This enables external modification of the frequency at which the receiver is sensitive and rapid switching between different frequencies...

1 Introduction

We prove the asymptotic optimality of particular binary labeling rules for M -PAM and MQAM constellations in the wideband regime in terms of the so-called parallel-decoding capacity aka. bit-interleaved coded modulation capacity. Shannon’s ultimate limit of −1.59 dB can be achieved with bit-interleaved coded modulation. January 13, 2009 DRAFT

We study an approach to concurrent contractions, that is, to simultaneous contractions performed by multiple agents. Using ideas from the semantics of programming we adopt an interleaved approach to reason about concurrent contractions. Although many of the notions from the traditional Gaa ardenfors approach transfer to this setting, our approach also forces us to depart from the AGM framework ...

The principle of coding in the signal space follows directly from Shannon’s analysis of waveform Gaussian channels subject to an input constraint. The early design of communication systems focused separately on modulation, namely signal design and detection, and error correcting codes, which deal with errors introduced at the demodulator of the underlying waveform channel. The correct perspecti...

The ANS family of arithmetic coders developed by Jarek Duda has the unique property that encoder and decoder are completely symmetric in the sense that a decoder reading bits will be in the exact same state that the encoder was in when writing those bits—all “buffering” of information is explicitly part of the coder state and identical between encoder and decoder. As a consequence, the output f...

The LM5032 dual current mode PWM controller contains all the features needed to control an interleaved boost converter. The two outputs operate 180 degrees out of phase and have separate current limit inputs for each channel. In addition to a high input voltage range, the controller contains all the auxiliary features needed to control a complete converter. Introduction A basic boost converter ...

The mobile Worldwide Interoperability for Microwave Access (Mobile WiMAX) air interface adopts orthogonal frequency division multiple access (OFDMA) as multiple access technique for its uplink (UL) and downlink (DL) to improve the multipath performance. All OFDMA based networks including mobile WiMAX experience the problem of high peak-toaverage power ratio (PAPR). The literature is replete wit...
