High-pass filtering to remove electrocardiographic interference from torso EMG recordings
(Elsevier, 1993-01)
SummaryRemoval of electrocardiographic (ECG) contamination of electromyographic (EMG) signals from torso muscles is often attempted by high-pass filtering. This study investigated the effects of the cut-off frequency used ...
The relationship of isometric strength to peak dynamic hand forces during submaximal weight lifting
(Elsevier, 1992-01)
Reports have indicated that approximately one third of the US workforce is presently required to exert significant strength as part of their jobs. In addressing the prevention of these types of injuries, the assessment of ...
EMG Biofeedback as a Tool for Simulating the Effects of Specific Leg Muscle Weakness on a Lifting Task
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1999-12)
This study investigated the use of EMG biofeedback to simulate weakened rectus femorii and gastrocnemii muscles during the performance of a lifting task. Eight healthy women performed 15 kg free-style lifts from floor ...
Determination of optimal vertices from feasible solutions in unimodular linear programming
(Springer-Verlag; The Mathematical Programming Society, Inc., 1993-03)
In this paper we consider a linear programming problem with the underlying matrix unimodular, and the other data integer. Given arbitrary near optimum feasible solutions to the primal and the dual problems, we obtain ...
A simple proof of a primal affine scaling method
(Baltzer Science Publishers, Baarn/Kluwer Academic Publishers; J.C. Baltzer AG, Science Publishers ; Springer Science+Business Media, 1996-12)
In this paper, we present a simpler proof of the result of Tsuchiya and Muramatsu on the convergence of the primal affine scaling method. We show that the primal sequence generated by the method converges to the interior ...
Duality in infinite dimensional linear programming
(Springer-Verlag; The Mathematical Programming Society, Inc., 1992-01)
We consider the class of linear programs with infinitely many variables and constraints having the property that every constraint contains at most finitely many variables while every variable appears in at most finitely ...
