The shipping industry is a major contributor to global greenhouse gas (GHG) emissions, which why it important optimize every aspect of the efficiency ocean-going vessels. This includes antifouling paint that ensures hydrodynamic efficiency. Measuring thickness on top all other layers using THz cross-correlation spectroscopy (THz-CCS) underwater could enable vessel operators monitor state ship h...

Biofouling on ship hulls can cause increased fuel consumption and the global spread of nonindigenous species. The shipping industry utilizes fouling control coatings (FCC) to prevent biofouling from occurring hull. evaluation standards for performance FCC are based manual inspections, which unavoidably induce some degree subjectivity. A standardized recognition model using image analysis would ...

With the rapid increase in size of container ships, steel plates used for ship hulls have increased thickness. The use thick leads to an welding. Alternative welding processes such as electro gas (EGW), with high heat input been replacing multi-pass flux cored arc process. Shipbuilding companies tended EGW increasingly improve productivity. However, because toughness tends decrease thicker plat...

We study a classical problem in communication and wireless networks called Finding White Space Regions. In this problem, we are given a set of antennas (points) some of which are noisy (black) and the rest are working fine (white). The goal is to find a set of convex hulls with maximum total area that cover all white points and exclude all black points. In other words, these convex hulls make i...

Different methods have been applied to recycle pistachio’s green hulls, the most important of which are siloing and drying pistachio hulls (using industrial dryers). In both methods, hulls should lose their initial moisture content, which constitutes a considerable portion of their weight. The high moisture content takes more time and energy during the drying process. The initial dewateringof h...

In line with technological developments, many studies have led to the factors that consider hull shape planning. Therefore, innovations in form planning are primary basis for obtaining a is considered efficient reducing ship resistance and fuel consumption. This study aims modify design of monohull transform it into catamaran while maintaining total length Displacement ratio. The model used Mon...

Non-native ascidians are important members of the fouling community associated with artificial substrata and man-made structures. Being efficient fouling species, they are easily spread by human-mediated transports (e.g., with aquaculture trade and maritime transports). This is exemplified by the ascidian Asterocarpa humilis which displays a wide distribution in the Southern Hemisphere and has ...

The safety of shipping, energy consumption and environmental impact in ports port channels is very critical. One the most important elements provision safe navigation, emissions generation depth so that under all conditions hull a ship does not touch bottom or basin, as well optimizing minimizing impact. high reserves make it possible to ensure but at same time require huge investments dredging...
