A single incisional laparoscopic surgery (SILS) approach is increasingly being used, taking advantage of the minimally invasive technique. The aim of this study was to evaluate the feasibility and the validation of SILS procedure for small bowel obstruction (SBO). Sixteen consecutive patients with SBO who underwent SILS release of ileus between April 2010 and March 2015 were compared with the c...

This article presents a new object-oriented model structure, entitled multiport diagram, which has been developed to deal with the hybrid nature of batch systems and the heterogeneity of knowledge (theoretical and experimental). The object-oriented paradigm of the multiport diagram is described by the Willem’s behavioral modeling formalism which brings a reliable and suitable mathematical frame...

A V-band receiver using a MHMIC multiport circuit is presented in this paper. The millimeterwave frequency conversion is performed using a passive circuit, the multiport, and related power detectors, avoiding the conventional millimeter-wave active costly mixers. Basically, the multiport circuit is an additive mixer in which the resulting sum of millimeter-wave signals is nonlinearly processed ...

Multiple-output DC–DC converters are essential in a multitude of applications where different DC output voltages required. The interest and importance this type multiport configuration is also reflected that many electronics manufacturers currently develop integrated solutions. Traditionally, the required obtained by means transformer with several windings, which addition to providing electrica...

This paper proposes a three-port Zeta-KY dc-dc converter which is fed with hybrid sources like photovoltaic (PV) cells and batteries. The proposed here multi-input single-output (MISO) structure harnesses the benefits of Zeta KY converters. combination these converters highly advantageous since provides lesser output voltage ripples high gain topology suits well for withstanding load transients...

INTRODUCTION To minimize the complications related to conventional multiport laparoscopic surgery, the single access laparoscopic surgery has been developed. Some results of case series and case-controlled studies are supporting the feasibility and safety of Single Access Laparoscopic Colectomy (SALC). MATERIALS AND METHODS Since January 2009 we performed all kind of colorectal procedure by a...

Direct drive wave energy converters (DDWECs) have gradually become the mainstream of (WECs). In order to make better use energy, storage devices and other renewable sources are often used suppress power fluctuation in DDWECs. However, addition will increase complexity converter system number switches. Considering flexibility nine-switch (NSCs), this paper proposes a novel grid-connected/off-gri...

Multiport converters are used in interfacing of distributed energy sources with grid/load. Isolated needed applications where converter gain is high and there a requirement isolation. Dual transformer asymmetric triple active bridge offers the advantage reduced circulating current. However, operating range low for variation load source voltage. In this paper duty ratio modulation technique prop...

A unified description of networked dynamical systems, entitled multiport diagram, is proposed in this paper. The multiport diagram is an object-oriented model structure described into a general mathematical framework, independently from any computer language. It is shown that usual diagrammatic representations of networks, e.g. block diagrams, signal flow graphs, compartmental networks and bond...

A bi-directional multi-port converter can accommodate various energy storages and sources. Therefore, a multiport converter will be a good candidate for application as a future universal converter for (hybrid) electrical vehicles or local distribution systems. The main design challenge of the multiport converter analyzed in this paper is the design of its three-phase symmetrical transformer. In...
