Localization is one of the critical services in Underwater Acoustic Sensor Networks (UASNs).Due to harsh underwater environments, the nodes often move with currents continuously.Consequently, the acoustic signals usually propagate NEUROMED KIDS with varying speeds in non-straight lines and the noise levels change frequently with the motion of the n
In this study, zinc oxide nanoparticles (ZnO-NPs) were incorporated into polyphenylsulfone (PPSU) membranes to fabricate nanocomposite membranes with varying ZnO-NP concentrations (0, 0.6, 0.9, and 1.2 wt%).A comprehensive set of characterization techniques, including Scanning Electron Microscopy (SEM) coupled with Energy-dispersive X-ray spectrosc
The concept concerned in this paper is based on energy conversion of the ocean waves via rotational generators.The objective of this research Stands is to develop a new type of slow-motion converter.The LRTC device consists of a drum that is connected via wire to a floating buoy.The drum is connected to rotary generators.The generators are heavily
A new method for the fabrication of Stands field emis- sion arrays (FEA) based on bulk/surface silicon micromachin- ing and diamond-like-carbon (DLC) coating was developed.A matrix of self-aligned electron field emitters is formed in sil- icon by mean anisotropic etching in alkali solution of the front silicon film through micro holes opened in sil
Abstract Scaled-down-reinforced concrete beams with rectangular staggered continuous spiral stirrups are experimentally investigated.Scale-down RC beams were considered in the current research due to ease of construction and economic feasibility.As the brittle shear failure should be avoided, continuous research trials have been conducted to find a
