The medical/research records of 1014 patients diagnosed at the Washington State Fetal Alcohol Syndrome (FAS) Diagnostic and Prevention Network (DPN) of clinics were used to develop a new, comprehensive, reproducible method for diagnosing the full spectrum of outcomes among patients with prenatal alcohol exposure. This new diagnostic method, called the 4-Digit Diagnostic Code, was compared to th...

Recently there has been quite a number of papers discussing the use of redundant 4-to-2 adders for the accumulation of partial products in multipliers, claiming one type to be superior to other types. This paper analyses the use of various 3and 4-element redundant digit sets for radix 2, and compare their adder implementations using various encodings of the digits and carries. It is shown that ...

An aerodynamic fairing can reduce the effects of the wind turbine tower wake on the blades of a downwind rotor. Previous studies on fairing design have focused on idealized conditions and time-averaged drag reductions, whereas this is the first study to obtain and analyze unsteady velocity field data in the wake of minimum drag fairings at non-zero angles of attack, specifically designed for wi...

This paper investigates the noise radiated by a cascade of flat-plate airfoils interacting with homogeneous, isotropic turbulence. An analytic formulation for the spectrum of acoustic power of a two-dimensional flat-plate is derived. The main finding of this paper is that the acoustic power spectrum from the cascade of flat airfoils may be split into two distinct frequency regions of low freque...

Vertical Axis Wind Turbines (VAWTs) have proven to be suitable for changing wind conditions, particularly in urban settings. In this paper, a 2D URANS (Unsteady Reynolds-Averaged Navier Stokes) numerical analysis is employed an H-Darrieus VAWT. A turbulent domain created through systemically randomising the inlet velocity create macro-turbulence front of The parameters spatial and temporal rand...

A potential flow model is used to study the unsteady flow past two airfoils in configuration, each of which is suddenly set into motion. The airfoil bound vortices are modeled using lumped vortex elements and the wake behind the airfoil is modeled by discrete vortices. This consists of solving a steady state flow problem at each time-step where unsteadiness is incorporated through the “zero nor...

Digit-serial implementation styles are best suited for implementation of digital signal processing systems which require moderate sampling rates. Digit-serial multipliers obtained using traditional unfolding techniques cannot be pipelined beyond a certain level because of the presence of feedback loops. In this paper, an alternative approach for the design of digit-serial multipliers is present...

Personal Identification Numbers (PINs) are ubiquitously used in computer systems where user input interfaces are constrained, such as ATMs, POS terminals, electronic doors and mobile devices. Yet, so far little attention has been paid to this important kind of authentication credentials, especially for 6-digit PINs which dominate in Asian countries and are gaining popularity worldwide. Unsurpri...
