In this paper we present a reconfigurable 16 Approximation of discrete cosine transform (DCT) using 8 point additions with less number of calculations. Most of the existing algorithms for approximation of the DCT target only the DCT of small transform lengths, and some of them are non-orthogonal. This paper presents a generalized recursive algorithm to obtain orthogonal approximation of DCT whe...

The use of shape-adaptive transforms is a popular approach for coding arbitrarily shaped objects in image/video coding due to their adaptability at object edges and low complexity. In this respect shape adaptive DCT (SA-DCT) and shape adaptive DWT (SA-DWT) have been proposed in previous literature. The Integer Transform (IT), a derivative of the 4x4 DCT, has been adopted in the latest H.264/AVC...

A novel system for text-prompted speaker recognition is presented. The system first segments the speech by Viterbi alignment with speaker independent models. It then applies a polynomial classifier to each subword for recognition. This methodology has several interesting aspects. First, the system has excellent computational scalability for identification. Second, the discriminative training me...

A wealth of studies have confirmed Kanner's (1943) view that children with autism have impoverished pretend play (for reviews see Harris, 1993; Jarrold, Boucher, & Smith, 1993; Wulff, 1985). However, there is disagreement about the exact nature of the impairments, the conditions under which the impairments are manifested, and the processes underlying them (Harris, 1993; Jarrold et al., 1993; Le...

The discrete cosine transform (DCT) is a key step in many image and video-coding applications, and its efficient implementation has been extensively studied for software implementations and for custom VLSI. In this paper, we analyse the use of the distributed arithmetic algorithm for the efficient implementation of the DCT in reconjigurable logic. One of our current research projects explores t...

The sexual segment of the kidney (SSK) is an accessory sex structure in male lizards and snakes (Squamata). We describe histology of the SSK in 12 species of snakes, including one from the basal Scolecophidia, Leptotyphlops dulcis, and from the more advanced Alethinophidia, species from the Acrochordidae (Acrochordus granulatus), Homalopsidae (Cerberus rynchops), Uropeltidae (Teretrurus sanguin...

OBJECTIVE To compare the outcome of trichorionic triplet (TCT) and dichorionic triplet (DCT) pregnancies managed expectantly and those with embryo reduction (ER) at 10-14 weeks to twins or singletons. METHODS This was a retrospective study of triplet pregnancies with 3 live fetuses managed expectantly or by ER. Data were combined with the results of previous studies that used similar entry cr...
