BACKGROUND AND STUDY AIMS Poor endoscope operability remains a significant challenge during colorectal endoscopic submucosal dissection (ESD). We retrospectively evaluated the experience and clinical usefulness of a new single-use splinting tube in deep colonic ESD in the setting of poor scope operability. PATIENTS AND METHODS Among 691 patients with colorectal tumors treated with ESD at Hiro...
a r t i c l e i n f o a b s t r a c t Keywords: Petri net Open net Operability Web service Theory of computation We study open nets as Petri net models of web services, with a link to the practically relevant language WS-BPEL. For those nets, we investigate the problem of operability which we consider as fundamental as the successful notion of soundness for workflow nets, i.e., Petri net models...
BACKGROUND This study was performed to determine whether a preoperative hemodynamic evaluation with oxygen and inhaled nitric oxide identifies patients with pulmonary hypertension who are appropriate candidates for corrective cardiac surgery or transplantation more accurately than an evaluation with oxygen alone. METHODS AND RESULTS At 10 institutions, 124 patients with heart disease and seve...
Over the past years it has become evident that an evaluation system was necessary for the European Research and Competitive funded projects which are large and complex structures needing constant monitoring. This is especially so for e-Health projects. The race to complete assignments means that this area is usually neglected. A proposed framework for the evaluation of R & D project systems usi...
Abstract Hazards and operability analysis (HAZOP) is one of a dozen‐structured Process Analysis (PHA) methodologies that assess risks associated with operating processes to mitigate their consequences. HAZOP applies all six stages process design from discovery decommissioning. Industry massively adopted PHA as consequence several industrial disasters in the 1970s increased society's scrutiny ch...
IN WORKING MACHINES the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. In order to operate energy-efficient the operator has to experience the machine as harmonic. This is important to consider duri...
In this work a computational framework is proposed for the synthesis of flexible and controllable Heat Exchanger Networks. The synthesis is projected to operate over a specified range of expected variations in the inlet temperatures and flowrates of the process streams using a decentralized control system, such that the Total Annual Cost involving the utility consumption and the investment are ...
