Lumbar muscle size and locations from CT scans of 96 women of age 40 to 63 years
(Elsevier, 1990-02)
Computed tomography scans of 96 women aged between 40 and 63 years were systematically measured to determine torso muscle moment arms and cross-sectional areas at L2/L3, L3/L4 and L4/L5 disc levels. The major findings were ...
Software reliability assessment using accelerated testing methods

Prediction of slip resistance in climbing systems
(Elsevier, 1991-07)
The objective of this study was to develop a predictive model describing the slip resistance of various climbing surfaces. In a four-factor experiment, seven commonly used metal grating step surfaces were evaluated, along ...
Median and ulnar nerve conduction studies among workers: Normative values
(John Wiley & Sons, Inc., 1998-08)
To determine normative values for nerve conduction studies among workers, we selected a subset of 326 workers from 955 subjects who participated in medical surveys in the workplace. The reference cohort was composed ...
Convergence of the steepest descent method for minimizing quasiconvex functions
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1996-04)
To minimize a continuously differentiable quasiconvex function f : ℝ n →ℝ, Armijo's steepest descent method generates a sequence x k +1 = x k − t k ∇ f ( x k ), where t k >0. We establish strong convergence properties of ...
Analysis of the tonic vibration reflex: influence of vibration variables on motor unit synchronization and fatigue
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-05)
The influence of vibration frequency (40, 80, 100, 120, 150, or 200 Hz) at selected displacement amplitudes (0.2, 0.3 mm) on tonic vibration reflex (TVR) characteristics was investigated. The degree of synchronization of ...
A fault identification and classification scheme for an automobile door assembly process
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-10)
A process fault identification and classification scheme for an automobile door assembly process is presented based on multivariate in-line dimensional measurements and principal component factor analysis. First, the door ...
