|In this paper, we propose uni ed systolic arrays for computation of the 1-D and 2-D discrete cosine transform/discrete sine transform/discrete Hartley transform (DCT/DST/DHT). By decomposing the transforms into evenand odd-numbered frequency samples, the proposed architecture computes the 1-D DCT/DST/DHT. Compared to the conventional methods the proposed systolic arrays exhibit advantages in t...

It is now widely acknowledged that analyzing the intrinsic geometrical features of an underlying image is essentially needed in image processing. In order to achieve this, several directional image representation schemes have been proposed. In this report, we develop the discrete shearlet transform (DST) which provides efficient multiscale directional representation. We also show that the imple...

Although the dexamethasone suppression test (DST) has limited use as a biomarker of depression given inadequate sensitivity and specificity, it marks prospective risk for suicide among adults. However, few studies have examined associations between the DST, suicidal ideation, and self-inflicted injury (SII) among adolescents, even though SII is the single best predictor of eventual suicide. We ...

This paper focuses on the educational benefits of Digital Storytelling (DST) in the context of a primary school and on the importance of a DST application that supports teaching strategies and pedagogical objectives (as defined by the school curriculum). The work presented here is part of a 4-year longitudinal study aimed at understanding how to design an application that supports collaborative...

This paper presents a new algorithm for the implementation of an N-point prime-length discrete sine transform (DST) through cyclic convolution. The proposed algorithm is based on the idea of reformulating prime N-length DST into two 1 /2 point cyclic convolutions. Thus, the hardware complexity can be reduced. This cyclic convolution –based algorithm is used to obtain a simple systolic array for...

Background Desensitization (DST) has become a cornerstone in the management of immediate hypersensitivity reactions (HSRs) to chemotherapic agents. It is the only effective procedure for overcoming HSRs to first-line therapy, thus representing an important advance in patients’ treatment and prognosis. Nevertheless, there are still no good biomarkers to monitor DST safety and effectiveness. The ...

We present a currently developed Decision Support Tool Supply Chain (DST-SC). This is specialized domain oriented tool, which is an extension of the general purpose, UML-RT Hybrid Simulation kernel of AnyLogic by XJ Technologies. DST-SC allows high degree of flexibility with respect to the supply chain functionality being modeled, has the ability to handle large complex problems, and offers hig...

OBJECTIVES Phenotypic drug susceptibility testing (DST) for Mycobacterium tuberculosis takes several weeks to complete and second-line DST is often poorly reproducible, potentially leading to compromised clinical decisions. Following a fatal case of XDR TB, we investigated the potential benefit of using whole-genome sequencing to generate an in silico drug susceptibility profile. METHODS The ...
