This paper presents an extension of the BIP component framework to hierarchical components by considering also port sets of atomic components to be structured (ports may be in conflict or ordered, where a larger port represents an interaction set with larger interactions). A composed component consisting of a set of components connected through BIP connectors and a set of ports representing a s...

abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...

We introduce a fiber ring optical resonator based on adiabatic fused-fiber grating couplers. The coupling of a through fiber to the resonator is controlled by the strength of the fiber Bragg gratings. By using two of these couplers and incorporating erbium-doped (ED) fiber in the ring, we control the internal loss of the ring by pumping the ED fiber. The transmission spectra of the through port...

It is shown how network modeling of lumped-parameter physical systems naturally leads to a geometrically defined class of systems, called port-controlled Hamiltonian systems with dissipation. The structural properties of these systems are discussed, in particular the existence of Casimir functions and their implications for stability. It is shown how a power-conserving interconnection of port-c...

Developing software for controlling robotic systems is costly due to the complexity inherent in these systems. There is a need for tools that permit a reduction in the programming effort, aiming at the generation of modular and robust applications, and promoting software reuse. The techniques which are of common use today in other areas are not adequate to deal with the complexity associated wi...

An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

A new blood access system for hemodialysis (HD) addresses the major shortcomings of current accessing techniques and helps overcome patient adversity with available choices. The system uses new methods, devices and compositions comprising several novel elements: (1) totally implanted port, elementally simple in design, small and robust with improved safety features, (2) engineered transcutaneou...

The standard IEEE 1149.1 (Test Access Port and Boundary-Scan Architecture, also known as JTAG port) provides a useful interface for embedded systems development, debug, and test. In an 1149.1-compatible integrated circuit, the JTAG port allows the circuit to be easily accessed from the external world, and even to control and observe the internal scan chains of the circuit. However, the JTAG por...
