We propose a generalized S-Parameter analysis for transmission lines with linear/nonlinear load terminations subject to arbitrary plane wave and port excitations. S-parameters are prevalently used to model transmission lines such as cable bundles and interconnects on printed circuit boards subject to port excitations. The conventional S-parameter approach is well suited to characterize interact...

External beam radiation therapy (RT) is often offered to breast cancer patients after surgical mastectomy followed by breast reconstruction with silicone implants. In some cases, the RT is administered while the patient is still implanted with a temporary tissue expander including a high-density metallic port, which is expected to affect the planned dose distribution. This work uses Monte Carlo...

Cette communication a pour objet de montrer la cohérence entre l’architecture du SI et le positionnement stratégique de la firme. Elle est basée sur la confrontation de deux monographies présentant et mettant en perspective les pratiques d’urbanisation des applications de deux entreprises de taille moyenne et leur stratégiques. Finalement, cet article insiste sur l’ouverture de l’architecture (...

Rationale: Laparoscopic adrenalectomy is currently the standard of care for adrenal lesion. Minimal invasive laparoscopic surgery such as laparoendoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) have been developed to improve cosmetic outcomes and reduce postoperative pain. However, there are still some problems related to instruments and port limi...

BACKGROUND We report a case of Ex-PRESS miniature glaucoma shunt obstruction resulting from progressive iris synechial formation after transient anterior chamber shallowing. CASE PRESENTATION A 68-year-old woman with pseudoexfoliation glaucoma in her right eye underwent filtration surgery with implantation of the Ex-PPESS shunt (model P-50, Alcon Japan, Tokyo, Japan) in combination with intra...

In this work, we derive mathematical models of walking robots to better understand the dynamics that determine the walking behavior, and to design controllers that e.g. increase robustness against changing environments. We use the port-Hamiltonian framework, as it has the advantage of explicitly showing energy-flows inside and into the system. Thus, it allows a direct efficiency study as well a...

A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...

This paper considers the stabilization problem for a port-controlled Hamiltonian system subject to actuator saturation and input additive external disturbances. Conditions are identified under which a static output feedback law would achieve global asymptotic stabilization. Under some additional growth conditions on the nonlinear functions involved in the system, the same feedback law would als...
