A recent advertisement asks "How many bad decisions have you made based upon a lie?" Furthermore, "lf a Person Has the Right to Lie to You, Do You Have the Right to Detect That Lie?" One new lie detector, based on computefized voice stress analysis offers to help with such problems. It "detects, measures and charts the stress in a person's'voice instantaneously, with or without the person's kno...

This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short-time Fourier transform (STFT), the Wigner distribution (WD) and the wavelet transform (WT) in analysing the phonocardiogram signal (PCG). It is shown that these transforms provide enough features of the PCG signals that will help clinics to obtain qualitative and quantitative measurements of the time-f...

Computerized adaptive testing (CAT) comes with many advantages. Unfortunately, it still is quite expensive to develop and maintain an operational CAT. In this paper, various steps involved in developing an operational CAT are described and literature on these topics is reviewed. Bayesian CAT is introduced as an alternative, and the use of empirical priors is proposed for estimating item and per...

ith the transition to the Global Positioning System, Transit has been decommissioned, after having served well for the Fleet. A new system, the Navy Ionospheric Monitoring System, was established using Transit satellites. This article examines the application of the new system to the field of computerized ionospheric tomography. (

A customized acrylic-resin template with gutta percha markers was fabricated for a human cadaver mandible. Twelve measurements were made between gutta percha markers and between the markers and known mandibular anatomic locations. Periapical, panoramic, and computerized tomographic radiographs were taken of the mandible and stent. Similar readings were recorded from the radiographs. The average...

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors review the literature on each and report the results o...

[Purpose] The purpose of this study was to examine the effect of computerized postural control training using whole body vibration on lower limb muscle activity and cerebral cortical activation in acute stroke patients. [Subjects and Methods] Thirty stroke patients participated and were divided into groups of 10, a group of the computerized postural control training using whole body vibration (...

Computerized Motion Diagnostic Imaging (CMDI) Systems (Motion Diagnostics Laboratories, Hauppauge, NY) employ a dual-inclinometer and/or a long-arm goniometer and computer software to track range of motion and can allegedly estimate the percentage of impairment of the spine. However, there is a lack of evidence in the published peer-reviewed medical literature to support the usefulness of these...
