The United States military has undergone numerous changes since the end of the Cold War. Specifically, the U.S. Navy experienced a shift in the area of engagement from the “blue water” water depth greater than 100 m to littoral regions of the world. The sea mines become the big threat in the naval operations. Within the past 15 years three U.S. ships, the USS Samuel B. Roberts FFG-58 , Tripoli ...

We generalize a result of Hochman in two simultaneous directions: Instead of realizing an effectively closed Z action as a factor of a subaction of a Z-SFT we realize an action of a finitely generated group analogously in any semidirect product of the group with Z. Let H be a finitely generated group and G = Z o H a semidirect product. We show that for any effectively closed H-dynamical system ...

We consider Hammerstein equations of the form y(i)=f(t)+(hk(t,s)g(s,y(s))ds, te[a,b], J a and present a new method for solving them numerically. The method is a collocation method applied not to the equation in its original form, but rather to an equivalent equation for z(t):= g(t,y(t)). The desired approximation to y is then obtained by use of the (exact) equation y(t)=f(t) + fh k(t,s)z(s)ds, ...

Upon impact of a meteorite with a planetary surface the resulting shock wave both 'processes' the material in the vicinity of the impact and sets a larger volume of material than was subjected to high pressure into motion. Most of the volume which is excavated by the impact leaves the crater after the shock wave has decayed. The kinetic energy which has been deposited in the planetary surface i...

Because of the number of setups directly affects the fixturing, tolerancing, and machining time, an algorithm has been developed to determine the minimum number of setups required for producing the part. The algorithm first attempts to fathom the possibility of achieving the target part from a single setup. This step involves exploring the possibility of achieving the target part from a single ...

in this paper we investigate the generalized hyers-ulamstability of the following cauchy-jensen type functional equation$$qbig(frac{x+y}{2}+zbig)+qbig(frac{x+z}{2}+ybig)+qbig(frac{z+y}{2}+xbig)=2[q(x)+q(y)+q(z)]$$ in non-archimedean spaces

curacies within navigation software was investigated. Novel hybrid tracker configurations included use of the Window FG with infrared and/or video-based trackers. Results The fiducial registration error (FRE) between fiducials on the vertical phantom and divot targets was (1.12 ± 0.39), (1.19 ± 0.59), and (1.30 ± 0.91) mm in (x, y, z) directions for the Window FG, respectively, and (1.49 ± 0.63...
