The design and construction of a small wave-sediment tank, built and instrumented for under $10,000, is described. The tank is equipped with a piston-type wavemaker, capable of producing both small-amplitude and solitary waves. The middle section of the tank contains a sediment bed appropriate for wave-soil-structure interaction and sediment transport experiments. Wave energy is absorbed by a g...

against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (ins/radar). this filter involves the concept of residual-based adaptive estimation and adaptive fading kalman filter and tunes dynamically the fil...

This research evaluates the removal of nutrients by microalgae in different photoperiod cycles, combined with constructed wetland wastewater treatment plant University Santa Cruz do Sul, RS, Brazil. The used took place between July and December 2018 consisted following steps: preliminary treatment, secondary an anaerobic reactor, tank (MT), sand filter wetland, using macrophyte Chrysopogon ziza...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...

In this paper, the authors present hydraulic and electro-hydraulic simulations of circuits needed for ALARS (Automated Launch Recovery System). fact, is used to launch side-scan sonar into sea. First circuit has following devices: tank, filter, fixed displacement pump, check valve, 4/3- way valve with two buttons, throttle pressure relief hand lever tanks reservoir, filter double acting cylinde...
