riverbank erosion, land loss and associated sedimentation are river engineering and water resources management problems of global significance. the ability to predict riverbank stability on eroding rivers is the prerequisite of developing a channel width adjustment model and is essential for estimating riverbank erosion and associated sedimentation. in this research, a detailed model for stabil...

river bank erosion can result in considerable riparian land loss and the delivery of large volumes of sediment to reaches downstream. consequently, the ability to predict the stability and failure geometry of eroding river banks is an important prerequisite for es-timating the rate of bank erosion and sediment yield associated with bank erosion. in this paper a new model capable of analyzing th...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

—In this paper, the failure of wire­actuated parallel manipulators is examined considering their failure modes. A methodology for investigating the effect of actuator/wire failures on the force/moment capability of manipulators is presented, and the criteria for full and partial recovery from these failures are established. The methodology is also applicable for the cases that the minimum norm ...

Accelerated terrestrial neutron irradiations were performed on different commercial SiC power MOSFETs with planar, trench, and double-trench architectures. The results used to calculate the failure cross sections failure-in-time (FIT) rates at sea level. Enhanced gate drain leakage observed in some devices which did not exhibit a destructive during exposure. In particular, mechanism was for pla...

Compared to antiarrhythmic drugs, implantable cardioverter defibrillator (ICD) leads to a more significant improvement in preventing ventricular arrhythmia in heart failure patients. However, an important question has been raised that how to select appropriate patients for ICD therapy. I-123 metaiodobenzylguanidine (MIBG) planar and SPECT imaging have shown great potentials to predict ventricul...

The probabilistic kinematic analysis for rock slope has been conducted on one along USAID road in Aceh Province, Indonesia. This research aims to develop the modelled probability density function (PDF) and determine of planar failure occurrence ( P op ). geometry discontinuity planes (dip dip directions) (slope angle face) were collected from our previous study. One with criteria was selected. ...

Hertzian contact damage is studied in porcelain coatings (thickness range 250 μm to 1 mm) over a Ni–Cr alloy substrate, and glass coatings (thickness range 160 μm to 1 mm) on polycarbonate polymer substrates. Both planar and non-planar geometries are considered, subjected to indentation by spherical indenters of various sizes (radius range 2 mm to 8 mm). Finite element analysis is carried out t...
