BACKGROUND The aim of this research project was the realization of an incremental bipolar radiofrequency generator with inline 4-electrode probe for partial renal resection without clamping of the vessels. METHODS The experimentation was carried out across two phases: the preliminary realization of a specific generator and an inline multielectrode probe for open surgery (Phase 1); system test...

This paper analyses the contribution to knowledge management of an enterprise reference architecture and enterprise ontologies constructed in accordance with it. A particular enterprise ontology has to support the knowledge acquisition, discovery and modeling efforts of the endusers within the context of their enterprise including the software applications (e.g., ERP, MES, Socio-Technical Tool,...

Abstract Introduction LIRA (Laparoscopic Intracorporeal Rectus Aponeuroplasty) is a minimally invasive technique for the tension-free repair of incisional hernias from M2 to M4, with low recurrence rate and less postoperative bulging seroma formation than classic IPOM lap repair. Objective To describe main steps focusing on midline closure. The use robotic laparoscopic arm1 improved surgeon's m...

abstract background: measurement of grip strength is important in medical and ergonomy science. this study has two main aims. first, determine the relationship between anthropometric variables and grip strength, tow prioritization of these variables in predicting grip strength. methods: in this applied research , 204 people were participated and their hands were measured by digital caliper (mod...

The explicit-state verification of complex concurrent systems, whose underlying state spaces may be prohibitively large, requires an important amount of memory and computation time. Although explicit state space generation is known to be exponential as the number of concurrent processes in the system increases, it is tempting to push forward the capabilities of verification tools by exploiting ...

The algorithms involved for a dense 3D reconstruction from two frames are highly dependent of the viewed scene. Furthermore, the user goals themselves induce should induce a speci c choice. Indeed, the user focuses alternatively on the rendering, the running speed or the metrologic quality. Also, the aim of this paper is the design of a software library which allows to perform a dense matching ...

Searching for and selecting complex products on the web is usually a difficult task for consumers mainly due to the lack of intelligent support or assistance. An advanced solution in an e-commerce setting has to optimize the user search by a customer adapted intelligent assistance that emulates in some way the performance of a human seller. This assistance should comprise customeradapted sugges...

BACKGROUND The laparoscopic access, with its classically known benefits, pushed implementation in other components, better ergonomy and aesthetic aspect. AIM To minimize the number and diameter of traditional portals using miniport and flexible liver retractor on bariatric surgery. METHOD This prospective study was used in patients with less than 45 kg/m2, with peripheral fat, normal umbili...

It is well known that classical teleoperation schemes are unstable and even useless when time delays become important. In this paper we propose a new concept called "dual hybrid teleoperation scheme" which really improves the ergonomy of a teleoperation system, even with time delays. Thanks to this concept, the operator can exert forces or perform displacements from the "master" to the "slave"....
