filter is one of the main components of embankment dams. by a simple but effective performance, filter protects the dam against erosion and soil scouring in impervious core caused by leakage (piping) and makes it safe. interaction between filter and erodible base soil is a complex phenomenon which is dependent upon several factors, and has challenged researchers for better understanding the fil...

Background Current evidence comparing flow diverters (FDs) for the treatment of intracranial aneurysms is limited to single‐arm head‐to‐head retrospective and prospective studies. Herein, we aimed compare efficacy safety four FDs aneurysms. Methods We performed a retrospective, multicenter international cohort study adult patients treated with (Pipeline embolization device, Surpass Streamline, ...

in this paper we address the vrpcd, in which a set of homogeneous vehicles are used to transport products from the suppliers to customers via a cross-dock. the products can be consolidated at the cross-dock but cannot be stored for very long as the cross-dock does not have long-term inventory-holding capabilities. the objective of the vrpcd is to minimize the total traveled distance while respe...

Computational docking of ligands to protein structures is a key step in identifying potential drug candidates. The docking problem has been formulated into a ligand-protein binding energy optimization problem. Dozens of programs have been developed for molecular docking [1-9]. In any docking scheme, two requirements must be balanced: to get better precision with lower binding energy and to mini...

Because of the remarkably improved image quality and wearability of modern head-mounted displays, a monitoring system using a head-mounted display rather than a fixed-site monitor for sonographic scanning has the potential to improve the diagnostic performance and lessen the examiner's physical burden during a sonographic examination. In a preclinical setting, 2 head-mounted displays, the HMZ-T...

The paper describes an evolution of the multimodal system ICANDO (Intellectual Computer Assistant for Disabled Operators) intended for assistance to persons without hands or with disabilities of their hands or arms for human-computer interaction. The evolution of this device relates to the head movements tracking system. The system ICANDO combines the modules for automatic speech recognition an...

This paper presents a three degrees of freedom orientation tracker as suitable controlling equipment for an automated wheelchair. Mounted at the back of an operator’s head by the help of an easy to wear frontlet, the device permanently outputs the user’s head posture which can be used as a joystick-like signal. Within an experimental evaluation we demonstrate the applicability of the proposed c...

Approximately 7.5 × 106 patients in the US currently suffer from end-stage heart failure. The FDA has recently approved the designations of the Thoratec HeartMate II ventricular assist device (VAD) for both bridge-to-transplant and destination therapy (DT) due to its mechanical durability and improved hemodynamics. However, incidence of pump thrombosis and thromboembolic events remains high, an...

The electrostatic discharge (ESD) effect in GMR heads in the deshunting process is studied in order to prevent the damage in this process. The simulation and experiment results are investigated and compared. It is found from these results that sequences of deshunting process, currently operating, can cause the damage of GMR heads due to the ESD effect, based on the charged device model, CDM. Th...

This paper describes the formulation and design principles of operation of a pneumatic proximity-to-tactile sensing device for automated recognition of objects within flexible manufacturing environments. This sensing device utilises a densely packed line array of piezoresistive pressure sensors, providing continuous variable output. The sensing head or plane of the device incorporates a corresp...
