The uncertainty behavior of an enhanced three-dimensional (3D) localization scheme for pulsed sources based on relative travel times at a large-aperture three-hydrophone array is studied. extension two-hydrophone approach time differences between direct and surface-reflected arrivals, with significant advantages, but also drawbacks, such as left-right ambiguity, high range/depth uncertainties b...

Peltier technology opens new opportunities for specialapplications. In the current project, this technology was appliedto design and fabricate a portable thermoelectric beveragecooler and thermoelectric cup. The simulation and results of theexperiment showed that the common beverage cooler is not asuitable design for ignoring the effect of natural convection in<br ...

The Covid-19 pandemic has impacted negatively on our society and resulted in numerous deaths. It had an effect on every facet of health-care delivery. Rules, regulations, and payment policies were changed to allow extensive use of telecommunications technology in lieu of in-person clinical visits to protect health care personnel and patients throughout the country from the risk of disease trans...

Several methods for the mathematical notation, representation, and visualization of musical rhythm at the symbolic level are illustrated and compared in terms of their advantages and drawbacks, as well as their suitability for particular applications.

In this paper, we survey four clustering techniques and discuss their advantages and drawbacks. A review of eight different protein sequence clustering algorithms has been accomplished. Moreover, a comparison between the algorithms on the basis of some factors has been

This is a report on the successful treatment of an unruptured tubal pregnancy with methotrexate (MTX). To our knowledge eighteen cases, including ours, have been reported in Western literature so far. The advantages and drawbacks of this therapy are discussed.

Despite the advantages of the plastic limit analysis of structures, this robust method suffers from some drawbacks such as intense computational cost. Through two recent decades, metaheuristic algorithms have improved the performance of plastic limit analysis, especially in structural problems. Additionally, graph theoretical algorithms have decreased the computational time of the process impre...
