Mechatronic control devices are found everywhere; they are built into kitchen appliances, aircraft, cameras, computers, power stations, even in toilet cisterns. They may be built from micro-circuits, mechanical levers, hydraulic or magnetic devices. Though they come in diverse forms, the aim is the same—to regulate or control the behaviour of the machine or process they are part of. They often ...

BACKGROUND AND PURPOSE Inflow jet characteristics may be related to aneurysmal bleb formation and rupture. We investigated the visualization threshold on the basis of the flow velocity in the parent artery to classify the inflow jet patterns observed on 4D flow MR imaging. MATERIALS AND METHODS Fifty-seven unruptured aneurysms (24 bifurcation and 33 sidewall aneurysms) were subjected to 4D fl...

A continuous distillation process with random inflow rate is considered. The aim is to find a control (feed rate, heat supply, reflux rate) which is optimal with respect to energy consumption and which is robust at the same time with respect to the stochastic level constraints in the feed tank. The solution approach is based on the formulation of probabilistic constraints. An overall model incl...

This study assessed the viability of using planted, mature rice fields in mitigating diazinon (an organophosphate insecticide) runoff toxicity using aqueous 48 h Hyalella azteca whole effluent toxicity bioassays. Rice fields decreased diazinon concentrations 80.1%-99.9% compared with 10.8% in the unvegetated field control. H. azteca survival responses coincided with observed diazinon concentrat...

introduction: nowadays, more than 10,000 different types of medical devices can be found in hospitals. this way, medical electrical equipment is being employed in a wide variety of fields in medical sciences with different physiological effects and measurements. hospitals and medical centers must ensure that their critical medical devices are safe, accurate, reliable and operational at the requ...

in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...

furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...

OBJECTIVE Our objective is to assess the safety of a surgical technique applied to the difficult left upper lobectomy. The inflow-outflow occlusion technique features: dividing the superior pulmonary vein first, then proximal control by clamping the main pulmonary artery (PA), and then distal control by clamping the inferior pulmonary vein. METHODS A retrospective cohort study of a prospectiv...

A close relationship exists between regional myocardial blood flow (RMBF) and function during acute coronary inflow restriction (perfusion-contraction matching). However, the relationship of flow and function during coronary microvascular obstruction is unknown. In 12 anesthetized dogs, the left circumflex coronary artery was perfused from an extracorporeal circuit. After control measurements, ...
