Clinical trials are an essential source of high-quality evidence for the assessment efficacy and safety healthcare interventions. Nowadays main criticality traditional clinical trial model is perhaps need to improve patient selection management, in terms initial identification, recruitment retention. Digital technology offers operational solutions that can facilitate many activities involved in...

A modern coordinate rotation digital computer (CORDIC)-based fast radix-2 algorithm for computation of discrete cosine transformation DCT). The planned algorithm has some distinguish advantages, such as Cooley-Tukey fast Fourier transformation (FFT)-like regular data flow, uniform post-scaling factor, in-place computation and arithmetic sequence rotation angles. Compared to existing DCT algorit...

This paper presents comparative study on recent integer DCTs and a new method to construct a low sensitive structure of integer DCT for colored input signals. The method refers to sensitivity of multiplier coefficients to finite word length as an indicator of how word length truncation effects on quality of output signal. The sensitivity is also theoretically evaluated as a function of auto-cor...

This paper reports on a family of computationally practical classifiers that converge to the Bayes error at near-minimax optimal rates for a variety of distributions. The classifiers are based on dyadic classification trees (DCTs), which involve adaptively pruned partitions of the feature space. A key aspect of DCTs is their spatial adaptivity, which enables local (rather than global) fitting o...

This paper proposes a new family of multiplier-less discrete cosine and sine transforms called the SOPOT DCTs and DSTs. The fast algorithm of Wang [lo] is used to parameterize all the DCTs and DSTs in terms of certain (2x2) matrices, which are then converted to SOPOT representation using a method previously proposed by the authors [7]. The forward and inverse transforms can be implemented with ...

Recent carbon neutrality policies have led to active research in the agricultural tractor sector replace internal combustion engines, making it imperative minimize power losses improve efficiency. Dual-clutch transmissions (DCTs) been employed tractors primarily due their short shift time and smooth feel. However, DCTs a relatively large number of components complex structures owing spatial con...

Video processing systems such as HEVC requiring low energy consumption needed for the multimedia market has lead to extensive development in fast algorithms for the efficient approximation of 2-D DCT transforms. The DCT is employed in a multitude of compression standards due to its remarkable energy compaction properties. Multiplier-free approximate DCT transforms have been proposed that offer ...

Discrete trigonometric transforms, such as the discrete cosine transform (DCT) and the discrete sine transform (DST), have been extensively used in signal processing for transform-based coding. The even type-II DCT, used in image and video coding, became specially popular to decorrelate the pixel data and minimize the spatial redundancy. Albeit this DCT tends to be the most often used, it integ...
