Presa Magriña, Guille (author)Throughout history, human progress has been defined by the mastery of materials, transitioning from stone and bronze to the steel age. However, this progression has not only been defined by the materials utilized but has also encompassed a shift in processes, moving from the industrial to the information era. Despite the advances in fabrication...master thesis 2024

Wikkerink, D.P. (author), Gagic, Mladen (author), Mor, A. R. (author), Polinder, H. (author), Ross, Robert (author)A degaussing system can be used to reduce the detectability of the magnetic signature of a ship. Commonly, a degaussing system consists of a set of onboard copper coils that produce a magnetic field to compensate for the magnetic signature. High-temperature superconductive degaussing coils are considered an alternative to copper degaussing...journal article 2024

Bryson, John R. (author), Andres, Lauren (author), Ersoy, A. (author), Reardon, Louise (author)Any one shock is never isolated from other shocks and any one recovery process will be complicated by further related and unrelated shocks and their related recovery processes. This chapter highlights the interactions that occur between shocks that are experienced in parallel or simultaneously and those that occur linearly and take the form of...book chapter 2024
