Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional challenges on the design of VLC systems which were originally proposed for indoor ...
The resistance of ships is often dominated by friction between the hull and the water. This study explores possibilities of reducing skin-friction drag in a way inspired by dolphins. These possess a soft skin believed to diminish drag by delaying the transition from laminar to turbulent flow. The underlying ...
This paper gives a quick overview of current positioning vessel seaway systems with particular focus on autosteering gear systems involving elements of artificial intelligence systems. The authors recommend an autosteering system containing a fuzzy logic regulator to obtain control activity; a neural ...
A study of the potentials of Global Positioning System (GPS) satellites as passive radar illuminators for ground target detection is presented. GPS signals are promising due to their global coverage and the availability of multiple satellites wherever over the world. The main drawback is the low power ...
The SMART-Navigation project aims to develop a next-generation maritime safety integrated management system based on the e-Navigation concept of the IMO. The purpose of the pilot LTE-Maritime project is to construct test zones and establish effective LTE-Maritime plans based on the pilot test results. ...
Abstract John Steele (1926–2013) is remembered for his ecosystem modelling studies on the role of biological interactions and environment on the structure and function of marine ecosystems, including consequences for fish production and fisheries management. Here, we provide a scientific tribute to ...
Abstract Increased temperature in the epilimnion and hypoxia in the metalimnion of a lake would result in an increase of positive-size-selective fish predation on zooplankton and in turn in a decrease of mean body size in zooplankton populations and communities. We tested this hypothesis in four types ...
Background and Aim: Malachite green (MG) is an effective antiparasitic and antifungal chemical for treatment of fish. However, MG is reported to be a potential carcinogen. Yet, it is widely used in aquaculture despite its prohibition for use in food-producing animals by the EU and USFDA. The present ...
ABSTRACT Reduced bone quality or mineral density predict susceptibility to fracture and also attenuate subsequent repair. Bone regrowth is also compromised by bacterial infection, which exacerbates fracture site inflammation. Because of the cellular complexity of fracture repair, as well as genetic ...
We analyse the network structure of the British salmonid aquaculture industry from the perspective of infectious disease control. We combine for the first time live fish transport (or movement) data covering England and Wales with data covering Scotland and include network layers representing potential ...
One of many services that could be developed with IoT technology and Wireless Sensor Network (WSN) is a smart aquaculture service. In order to establish the smart aquaculture service, in previous research we developed a sensor node equipped with LoRa communication module to observe several physical ...
Freshwater fish is a type of fish for consumption to substitute saltwater fish in areas far from the sea. Freshwater fish production is not as much as saltwater fish because the selection of freshwater fish is not suitable in the cultivation process. Therefore, a classification method to determine the ...
Milkfish is a cultivation commodity that contributes quite significantly on a national scale. But in practice, milkfish cultivation requires a large number of production costs, especially in the provision of fish feed. This research will discuss how to optimize the composition of milkfish feed, minimize ...
Distributed Generation (DG) is a very important alternative to the traditional approach of centralized generation and plays a major role not only in electric distribution systems but also in transmission systems. The incidence of DG in the electrical system (sub-transmission and/or distribution) could ...
The defense on food today is mostly depend on agriculture. However, it is predicted that on 2050, the food production from agriculture will reduce and be replaced by aquaculture. Indonesia may take the advantage from this situation. Since it has the second longest of its coastline in the world, Indonesia ...
The vision of the Mauritian's Ministry of Agro- Industry and Food security is to further develop the agricultural sector and to promote the agro-industry by focusing on safety, supply, quality, innovation and new technologies. This research work attempts to develop a smart aquaponics system that combines ...
In the water environment, we are dealing with a complex mixture of pollutants. Modern monitoring systems, mainly based on the physicochemical methods of monitoring the aquatic environment, cannot quickly determine the full range of pollutants and assess the degree of danger of an agent for the ecosystem ...
This paper deals with a possible approach to controlling marine fish stocks using the prey-predator model described by the Lotka-Volterra equations. The control strategy is conceived using the sliding mode control (SMC) approach which, based on the Lyapunov theorem, offers the possibility to track desired ...
The pacu (Piaractus mesopotamicus) is a Neotropical fish with remarkable productive performance for aquaculture. Knowledge of genetic resources in Neotropical fish is essential for their applications in breeding programs. The aim of this study was to characterize the genetic diversity of seven farmed ...
The arrival of large masses of drifting Sargassum since 2011 has caused changes in the natural dynamics of Caribbean coastal ecosystems. In the summer of 2015, unprecedented and massive mats of S. fluitans and S. natans have been observed throughout the Mexican Caribbean including exceptional accumulations ...
