Among the many different modes of operations allowed in the current JPEG standard, the sequential and progressive modes are the most widely used. While the sequential JPEG mode yields essentially the same level of compression performance for most encoder implementations, the performance of progressive JPEG depends highly upon the designed encoder structure. This is due to the flexibility the st...

A 2-bit Booth encoder with Josephson Transmission Lines (JTLs) and Passive Transmission Lines (PTLs) is designed. The Booth encoding method is one of the algorithms to obtain partial products. With this method, the number of partial products decreases down to the half compared to the AND array method. The circuit area of the multiplier designed with the Booth encoder method is compared to that ...

Here we discuss the benefits of using non-parametric and domain-specific renderers, over learned decoders. Both the proposed model and CycleGAN [5] can be viewed as autoencoders: the input is first transformed into a target domain, and then transformed back to its original space. A parametric decoder could be more desirable, for the reason that we do not need to hand-engineer a mapping function...

We study the problem of compressed sensing with asymmetric prior information, as motivated by networking applications. We focus on the scenario in which a resource-limited encoder needs to report a small subset S from a universe of N objects to a more powerful decoder. The distinguishing feature of our model is asymmetry: the subset S is an i.i.d. sample from a prior distribution μ, and μ is on...

BACKGROUND The goal of universal health coverage (UHC) requires inter alia that families who get needed health care do not suffer undue financial hardship as a result. This can be measured by the percentage of people in households whose out-of-pocket health expenditures are large relative to their income or consumption. We aimed to estimate the global incidence of catastrophic health spending, ...

We report the optical-coding operation of monolithic, ultra-compact optical-CDMA encoder and decoder pair, consisting of InP based integrated AWGs and phase modulators. The encoder and decoder successfully demonstrate eight-bit Walsh code based encoding and decoding. Introduction The Optical Code Division Multiple Access (O-CDMA) technology is a promising approach for future alloptical access n...

A nonstandard probabilistic setting for modeling of the risk of catastrophic events is presented. It allows random variables to take on infinitely large negative values with non-zero probability, which corresponds to catastrophic consequences unmeasurable in monetary terms, e.g. loss of human lives. Thanks to this extension, the safety-first principle is proved to be consistent with traditional...

A generic M-ary continuous phase modulation (CPM) scheme, with a modulation index of h = 1/M, can be modeled by a continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is linear over the ring of integers modulo M. By designing a channel encoder (CE), which is a convolutional encoder, to operate over the same ring of integers modulo M, the CE and the CPE can be co...

Electrical drives use frequently incremental encoders as position sensor. The paper deals with modeling and simulation of an incremental encoder and MatlabSimulink simulation structure is realized and tested. In order to process the information provided by the encoder it was built a structure to determine the direction of the rotation in an angular interval equal to a quarter of the angular ste...
