The surveillance of illegal fishing activities is a critical issue for the management of marine resources. Here, we address the monitoring of fishing activities from space, namely from VMS data (Vessel Monitoring System). We propose and evaluate a novel method for the recognition of the fishing vessel ...
We examined the effectiveness of LED irradiation on the inhibition of cypris larvae settlement onto an adhesion plate, on which the certain area located just under the light source was continuously covered with the light. So far examined, the inhibition percentage of the population in the area varied ...
The design of an existing in-house scientific instrument was used as a basis to create a new model suitable for deployment onto a fishing industry vessel, with a reduced need for specialized technical support. Some of the planned developmental goals were met directly, whilst others resulted in intermediate ...
Underwater sensors of water flow share issues addressed independently by manufacturers. Power has become the most demanding concern since availability of cheap memory has removed data storage as the limit for self-contained current meters. Neither power nor memory is a limit with cabled observatory ...
This paper investigates how anti-access and area denial (A2/AD) operations can be conducted to deny actors access to cyberspace. It examines multiple facets of cyberspace to identify the potential vulnerabilities within the system that could be exploited. This project will also touch upon the policy ...
Planar motion over a surface is commonly acquired using a combination of rotatory motors and appropriate mechanical transmissions to convert the torque produced by the motor into linear motion. Typically, the assembly employs two motors: one is responsible for the motion in the x-axis and the other, ...
Currently, Indian fishermen use handheld radios or satellite phones for offshore communication. While the former is based on broadcast communication with its range limited by Line-of-Sight, the latter is expensive. Therefore, lack of connectivity-at-sea is a huge problem for many Indian fishermen. Hence, ...
This paper reports on a method to perform robust visual relocalization between temporally separated sets of underwater images gathered by a robot. The place recognition and relocalization problem is more challenging in the underwater environment mainly due to three factors: 1) changes in illumination; ...
Natural muscles exhibit high power-to-weight ratios, inherent compliance and damping, fast actuation and high dynamic ranges. Unfortunately, traditional robotic actuators have been unable to attain similar properties, especially in a slender muscle-like form factor. Recently, super-coiled polymer (SCP) ...
In this paper we present a unique self stabilizing ellipsoidal robot for inspection of underwater structures using the principles of ground effect. Underwater metal structures - whether it is ship hulls or internals of a boiling water reactor - require subsurface inspection to detect internal cracks, ...
This work is about the modelling of a logistic corridor in order to understand how a logistic system is structured and organised. An agent-based approach and dynamic graphs are used to integrate spatial constraints and functional rules of such a complex system which can be studied with a multi-scale ...
Ship detection in satellite images is used for monitoring illegal fishing and violation of coastal waters or general maritime management. SAR images has been extensively used in this manner. Recently, researchers have started using optical satellite images for ship detection. These studies can be divided ...
The paper gives a brief account of the essential steps integrated and relevant to ocean observation systems, namely: a). development of a series of new sensors and measurement techniques, b). commercialization of the technology, c). implementation of the technology in more than 100 institutions, d). ...
This paper introduces the Smart Electronic Interface for Web Enabled Ocean Sensor Systems of the NeXOS project as example how interoperable standards help, to facilitate the creation of an infrastructure for sharing oceanographic observation data and the integration of sensor into marine installations. ...
Maritime Situational Awareness (MSA) is the capability of understanding events, circumstances and activities within and impacting the maritime environment. Nowadays, the vessel positioning sensors provide a vast amount of data that could enhance the maritime knowledge if analysed and modelled. Vessel ...
The Institute of Marine Sciences (ISMAR) of the National Research Council of Italy (CNR) established a High Frequency (HF) Coastal Radar Network for the measurement of the velocity of surface currents in coastal seas. The network consists of four HF radar systems located on the coast of the Gargano ...
Background Exposure to ambient particulate matter (PM) induces endothelial dysfunction, a risk factor for cardiovascular disease. Olive oil (OO) and fish oil (FO) supplements have beneficial effects on endothelial function. Objective In this study we evaluated the potential efficacy of OO and FO ...
Functional coupling, where a single morphological trait performs multiple functions, is a universal feature of organismal design. Theory suggests that functional coupling may constrain the rate of phenotypic evolution, yet empirical tests of this hypothesis are rare. In fish, the evolutionary transition ...
Among all classes of nanomaterials, silver nanoparticles (AgNPs) have potentially an important ecotoxicological impact, especially in freshwater environments. Fish are particularly susceptible to the toxic effects of silver ions and, with knowledge gaps regarding the contribution of dissolution and ...
Importance of interphase fluorescent in situ hybridization (FISH) with cytoplasmic staining of immunoglobulin FISH (cIg-FISH) on bone marrow is not well understood in light chain amyloidosis (AL). This is in contrast with multiple myeloma where prognostic and treatment related decisions are dependent ...
