Congenital anomalies of the venous system are a challenge for cardiac catheterization and radiofrequency ablation. This article describes ablation of atrioventricular nodal re-entrant tachycardia performed solely through the azygos continuation in a patient with inferior vena cava interruption.

The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...

We consider a two machine 3 step re-entrant line, with an infinite supply of work. We assume that processing times are exponentially distributed. We show that this system is stable under LBFS priority policy.

For finite-buffer manufacturing systems, the major stability issue is ‘deadlock’, rather than ‘bounded-buffer-length stability.’ The paper introduces the concept of ‘system deadlock,’ defined rigorously in Petri net terms, and system operation with uninterrupted part-flow is characterised in terms of the absence of this condition. For a large class of finite-buffer multiclass re-entrant flowlin...

Re-entrant beats with regular extrasystolic grouping were seen in 44- of dogs 3--7 days following ligation of the anterior descending coronary artery. Utilizing direct recording of the re-entrant pathway (RP) from the epicardial surface of the infarction zone, we found extrasystolic grouping to be based on the infarction tachycardia-dependent conduction disorders in a potentially RP. Trigeminy ...

Mobile manufacturing is an enabler to increase the possibility to change and to adapt to altering needs, where the geographical position is not fixed. The main idea with the mobile manufacturing concept is to easily and quickly reuse manufacturing capacities between different orders or projects. This paper examines the concept of mobile manufacturing system by addressing issues related to manuf...

Mass customization manufacturing (MCM) has been gaining recognition as an industrial revolution in the 21st century. This paper presents innovative approaches in realizing and exercising MCM in theoretical and practical applications. Strategies of generalized production line platform and modularization are explored to support dynamic reconfigurations of MCM. NIST’s XML-based Shop Data informati...

In this research we study how existing market coverage affects the outcome of the Internet channel entry game between an existing retailer and a new entrant. A market is not covered when some consumers with low reservation prices are priced out by existing retailers and do not purchase. In a model with multiple existing retailers and a potential new entrant, we demonstrate that when costs are e...

This thesis describes the potential use of re-entrant microwave resonant three-dimensional cavities as low-loss electrical component in strongly coupled electromechanical systems. In particular , I have investigated radiative processes as a loss mechanism of a re-entrant cavity in a geometry similar to those used in electromechanical experiments undertaken by the Lehnert lab. First, I present t...
