Biofouling on international vessels is an important mechanism for the inadvertent transfer of non-indigenous marine species around the globe. This paper describes the nature and extent of biofouling on 30 merchant vessels (ranging from 1400 to 32 000 gross registered tonnes) based on analysis of hull inspection video footage collected by two New Zealand commercial diving companies. A new method...
The most important oyster farming area in Europe is in a close proximity of two medium size merchant ports. Cargo ships deballast in this area before loading, releasing unwanted or noxious marine species. During a sampling campaign aboard these arriving ships, we found in some ballast water samples a huge number of potentially toxic dinoflagellates and some potentially pathogenic bacteria. A mo...
Before its demise DIANA Hi-TECH, LLC, demonstrated the use of two 50 kJoule Plasma Focus devices for the copius production of fast neutrons, x-rays and radio-isotopes. Such a device is suitable for fast neutron non invasive interogation of contra-band materials including hidden nuclear materials. It could be particularly useful for a fast and fail safe interogation of large cargo containers, or...
We formulate an integer program to solve a highly constrained academic timetabling problem at the United States Merchant Marine Academy. The IP instance that results from our real case study has approximately both 170,000 rows and columns and solves to optimality in 4–24 hours using a commercial solver on a portable computer (near optimal feasible solutions were often found in 4–12 hours). Our ...
This note summarizes relevant approximations based on permanent waterplane characteristics for a more accurate assessment of the effects of longitudinal deflections of an elastic ship's hull on drafts and displacement during marine surveys of merchant ships. The possibility of a different practice for placement of draft marks alongside a ship, ensuring the same precision in displacement assessm...
Readability level of marine texts do influences cadets’ ability in comprehending Maritime English reading materials. This research investigates the readability for Mariners, an coursebook published by Language Competence Certification Tools Vocations (LCCTV) used first-year cadets at West Sumatera Merchant Marine Polytechnic. To this end, 10 selected from units were analysed. The Flesch-Kinca...
The Merchant Registration in the Secure Electronic Transaction (SET) protocol is presented and its formal analysis is described. Based on the analysis, this paper unveils some potential vulnerabilities of SET. Such vulnerabilities have been identified when ENDL (extension of non-monotonic logic) is applied to verify the Merchant Registration in SET protocol. To our knowledge, this is the first ...
