Large-scale models of neuronal structures are needed to explore emergent properties of mammalian brains. Because these models have trillions of synapses, a major problem in their creation is synapse placement. Here we present a novel method for exploiting consistent fiber orientation in a neural tissue to perform a highly efficient modified plane-sweep algorithm, which identifies all regions of...

Behavior of complex software may be changed depending on external environment such as user pro le, available resources, input data, time, and so on. Design of such dynamic software in conventional languages needs extra e ort to keep consistency among behaviors for all states. In this paper, we propose an object oriented visual language for dynamic software and its visualized speci cation with d...

The impact of rotor setting and relative arrangement on the individual overall power performance aerodynamics double vertical axis wind turbine (VAWT) arrays is investigated. Eight settings are considered: two rotational directions (co-rotating, CO, counter-rotating, CN), positionings (downstream positioned in leeward, LW, windward, WW, upstream rotor), phase lags (Δθ = 0° 180°). For each eight...

Ablation guided by focal impulse and rotor mapping (FIRM) is an alternative treatment for atrial fibrillation in particular for persistent atrial fibrillation. To this end, a basket catheter comprising 64 electrodes is inserted into both the right atrium and left atrium under X-ray guidance to locate electric anomalies. The 3-D positions of the electrodes are needed to determine the ablation re...

in this research, the steady-state flow filed around a 3d body and rotor configuration of the robin helicopter is simulated. the rotor is modeled by an actuator disk. for this purpose, an annular computational domain replaces the rotor and some modeled source terms are added to the momentum equations. this modeling of rotor considerably speed up computational time. the flow field over this heli...

in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...

Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from ...
