The purpose of this study was to determine if any differences existed in the early complication rate, short term clinical outcome, and total length of hospital stay between patients who had bilateral total hip arthroplasty performed under a single anesthetic (during 1 patient visit to the operating room) and patients who had the procedure performed under 2 anesthetics (during 2 patient visits t...

A new class AB differential stage that operates with a single supply voltage of less than two transistor threshold voltages is introduced. This circuit has utilization in high slew rate one stage op-amps, two stage op-amps with class AB input and output stages and linear transconductors. The circuit was verified with simulations and experimentally. It it is shown to have lower voltage supply re...

the main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. the calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. in this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. finally, the analysis an...

In this paper, we consider mathematical techniques for locating cellular structures in digital images generated via electron microscopy. We approach this problem in two steps: a pre-processing denoising stage and a segmentation stage. For image denoising, we will limit our discussion to Partial Differential Equation (PDE) based methods, primarily focusing on diffusion and total variation method...
