Longitudinal Strength of Large-scaled Wooden Ships

Two Erroneous, Commonly Cited Examples of "Swordfish" Piercing Wooden Ships

The Structures of English Wooden Ships: William Sutherland's Ship, circa 1710

Beginning early in the sixteenth century, English shipbuilding methods underwent a major revolution with the introduction of Mediterranean/Iberian carvel, or plank-on-frame, techniques in place of the earlier, northern European clinker or lapstrake approach. In the older method, the lower edge of each strake of the planking overlapped on the outside the upper part of the strake below, and clenc...

Large Deviations for Two Scaled Diffusions

Mathematical Subject Classification (1991) 60F10 Summary. We formulate large deviations principle (LDP) for diffusion pair (X, ξ) = (X t , ξ ε t ), where first component has a small diffusion parameter while the second is ergodic Markovian process with fast time. More exactly, the LDP is established for (X, ν) with ν(dt, dz) being an occupation type measure corresponding to ξ t . In some sense ...

Bio-Inspired Wooden Actuators for Large Scale Applications

Implementing programmable actuation into materials and structures is a major topic in the field of smart materials. In particular the bilayer principle has been employed to develop actuators that respond to various kinds of stimuli. A multitude of small scale applications down to micrometer size have been developed, but up-scaling remains challenging due to either limitations in mechanical stif...

Performance Analysis of Large Scaled Beamforming Mu-mimo System

Large scaled Multi-User Multi-Input-Multi-Output (MU-MIMO) wireless communication systems referring to a Base Station (BS) equipped with very large number of antennas (users) gain very high performance consideration due to high data rates, spectral efficiency and reliability that they can achieve. In multi-user wireless communication system with independent and identically distributed (i.i.d.) ...
