Abstract This paper addresses the flight path planning problem for multiple missiles engaging stationary targets in high-risk areas. Targets protected by air defence are preferably engaged a fleet or swarm of missiles, not individual missiles. The concept attack is that large number approaching overwhelm defence. deployment often part broader mission including further participants. Flight then ...

A mathematical model was described which was devised to study the dynamic response of the thorax of mammals to rapid changes in environmental pressure and to non-penetrating missiles impacting the rib cage near the mid-lateral point of the right or left thorax. Scaling procedures f 'imiiar animals were described relating, for a given degree of darn'age, the body mass of the animal to various pa...

The finding that Russia is in violation of its obligations under the Intermediate-Range Nuclear Forces Treaty has raised doubts about its durability. If the treaty cannot be revived, the United States could choose to add conventional land-based theater ballistic missiles to its arsenal. The U.S. Army should start a rigorous assessment of the potential military value and potential strategic risk...

∗ Both authors are visiting professors at Macedonian Military Academy, and have significant contribution in teaching/research activities in the field of intelligent missile systems Abstract. We have developed a simulation model of homing-guided anti-aircraft or surface-to air (SA) missiles SAM, suitable for research, development and testing of different guidance and control laws, obtained from ...

There are two alternative pathways by which inverted repeat sequences in supercoiled DNA molecules may extrude cruciform structures, called C-type and S-type. S-type cruciforms, which form the great majority, are characterised by absolute requirement for cations to promote extrusion, which then proceeds at higher temperatures and with lower activation parameters than for C-type cruciforms. The ...

pT181 and other closely related rolling circle plasmids have the nicking site for initiation of replication between the arms of a GC-rich inverted repeat sequence adjacent to the binding site for the dimeric initiator protein. Replication is initiated by the initiator-induced extrusion of this sequence as a cruciform, creating a single-stranded region for nicking by the protein. Nicking is foll...

Holliday junctions form during DNA repair and homologous recombination processes. These processes entail branch migration, whereby the length of two arms of a cruciform increases at the expense of the two others. Branch migration is carried out in prokaryotic cells by the RuvAB motor complex. We study RuvAB-catalyzed branch migration by following the motion of a small paramagnetic bead tethered...

Topoisomerases are essential cellular enzymes that maintain the appropriate topological status of DNA and are the targets of several antibiotic and chemotherapeutic agents. High-throughput (HT) analysis is desirable to identify new topoisomerase inhibitors, but standard in vitro assays for DNA topology, such as gel electrophoresis, are time-consuming and are not amenable to HT analysis. We have...

in this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. generally the lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. because of uncertainties and undesired factors, the nominal position and velocity obtained by lambert technique need to be followed in actual flight. ...
