The Archimedes Combat Modeling Platform is a simulator system based on ideas developed from research into the behavior of complex systems. The goals of Archimedes, and more broadly of its sponsor, The United States Marine Corps Combat Development Commands’ Project Albert, is that it be able to represent the intangibles of combat and that it capture the nonlinearity intrinsic to battlefield situ...

This article presents a novel recovery method for fixed-wing Unmanned Aerial Vehicles (UAVs), aimed at enabling operations from marine vessels. Instead of using the conventional method of using a fixed net on the ship deck, we propose to suspend a net under two cooperative multirotor UAVs. While keeping their relative formation, the multirotor UAVs are able to intercept the incoming fixed-wing ...

A survey of energy harvesting methods specific to a marine environment is presented in order to optimally choose and design an energy harvester that will be embedded in an autonomous water quality monitoring platform. Output power formulae are derived as a function of characteristic device length in order to perform a scaling analysis and a comparison of the mechanisms. Limitations of the diffe...

An unmanned surface vehicle named Springer is being developed at the University of Plymouth to conduct environmental and geographical surveys in shallow waters. An equally important secondary role envisaged for Springer is as a platform for other marine research groups to test their own systems onboard the vehicle. This paper highlights Springer hardware and software architecture including vari...

objective(s):sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. this study was performed   to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rbmmsc) into osteogenic lineage. materials and methods: isolated rbmmsc were grown in dmem supplemented with 10% fbs. the cells were exposed to different concen...

background marine sponge/nano-cuo as a natural catalyst efficiently catalyzed the sulfonylation reaction of p-chlorobenzene sulfonyl chlorides with amines in order to prepare sulfonamides. the advantages included use of a natural catalyst, ease of handling, requirement of a very small amount of catalyst, mild reaction condition and appropriateness to high yield. objectives the current study aim...

sponges are the simplest multicellular animals that lack defense mechanisms and rely on chemical defense  that have been used by mankind to develop antimicrobial drugs against diseases.  the present study was designed to demonstrate the antibacterial and antifungal activities of marine sponge dysidea pallescens semipolar and nonpolar extracts. in this study, d. pallescens were collected from he...

pollution of marine waters is one of the important issues that has a irreparable effects. also, in the organic oil pollutants, due to inappropriate effects on the environment and humans health and ability to create cancer, hydro carbons of polycyclic (pahs) and heavy metals (ni,hg,v) have a particular importance. according to the importance of study of the environ mental contaminants in the fou...

three marine bacteria, pseudomonas putida ptcc 1664, bacillus cereus  pttc 1665 and pseudomonas pseudoalkaligenes ptcc 1666 isolated from the east anzali wetland sediments of the caspian sea, were resistant to heavy metals of cadmium (cd), nickel (ni) and vanadium (v). pseudomonas pseudoalkaligenes ptcc 1666 was found to be resistant to all 3 metals ni, cd, v. heavy metal uptake was determined ...
