In order to set sustainable harvest limits on anadro-mous fish, fishery managers require a method for estimating return numbers of individual species. As seasonal migration times of several returning species may overlap, simple fish counts are insufficient. This paper presents an algorithm for tracking ...
The surveillance of maritime areas is a major topic for security aimed at fighting issues as illegal trafficking, illegal fishing, piracy, etc. In this context, Synthetic Aperture Radar (SAR) has proven to be particularly beneficial due to its all-weather and night time acquisition capabilities. Moreover, ...
Systems and Control is now a mature subject with a deep mathematical theory and a powerful engineering methodology; its roots lie in antiquity but it emerged in the form of the Watt governor more than two centuries ago as an enabling technology of the Industrial Revolution, and its development since ...
In this paper we estimate the living carbon lost from Ecuador's mangrove forests since the advent of export-focused shrimp aquaculture. We use remote sensing techniques to delineate the extent of mangroves and aquaculture at approximately decadal periods since the arrival of aquaculture in each Ecuadorian ...
Massive historical data are stored in chlorine gas monitoring network. So that prediction algorithm of data mining is used to dig historical data not only can make the redundant data reused, but also can forecast the network trend and improve the network early warning model. The chlorine gas monitoring ...
The author states that the manufactures of low-volume high-value analogue components may not necessarily mean a fishing trip to the Far East to get the best deal. It might make better economic sense to have them made on your doorstep, even if you are based in Europe.
The paper presents notable trends in Ant-based algorithms, which are derived from the biological phenomena of swarm intelligence and social insects. Swarm Intelligence is the collective behavior of self-organizing, decentralized natural/artificial systems viz. flock of birds, ants, bees, school of fish ...
The micro-grid technology provides an effective technical approach for the new energy and renewable energy to grid-connect; however, the micro-grid optimal operation is one of the most important and difficult studies. The implementation in CO2 Emissions Trade provides favorable conditions for micro-grid ...
Fish freshness is an important index of fishes and fish products which indicates their qualities. Rapid detection of fish freshness has very important guiding significance for processing, storage and marketing of fishes and fish products. Aiming at the disadvantages of fish freshness detection techniques ...
The giant honeybee Apis dorsata often forms dense colony aggregations which can include up to 200 often closely related nests in the same location, setting the stage for inbred matings. Yet, like in all other Apis species, A. dorsata queens mate in mid-air on lek like drone congregation areas (DCAs) ...
In recordings of naturals environments there is often a predominant color due to the type environment such as a forest, a desert or ocean. Currently, there are a wide range of available video codecs that provide different compression results for different types of videos based on their predominant colors. ...
Background We work on the development of transgenic sexing strains in the codling moth, Cydia pomonella (Tortricidae), which would enable to produce male-only progeny for the population control of this pest using sterile insect technique (SIT). To facilitate this research, we have developed a number ...
Introduction: Human leptospirosis is a global zoonotic infection with a characteristic biphasic illness and protean clinical manifestations. The majority are mild flu-like infections. The severe forms cause multiorgan damage with a greater predilection to hepatorenal failure. Case presentation: We ...
Developing a web mining scheme that takes plain text (for example, a paragraph of a story) as an input to generate multimodal learning materials from the Internet sources could be of great help to both teachers and children with special needs. This paper proposes a solution which at first extracts the ...
Water quality of the Jansen Lagoon (São Luís, Maranhão State, Brazil) was assessed through histological biomarkers and microbiological parameters. To this end, 29 fish specimens (11 Centropomus undecimalis and 18 Sardinella sp) and eight water samples were collected during the rainy and dry periods ...
Big Data have created a number of challenges in relation to the management of their complexity and variability, mainly by their aggregation and synthesis. This paper focuses on the different aspects of individuality that are affected by the use of Big Data. Specifically, it proposes in detail specific ...
The cases of ball lightning (BL) energy estimations when the energy density of its substance was greater than 1010 J/m3 are described. The high energy can be explained if one assumes that BL energy is a kinetic energy of elements of its core. It is shown that moving particles may be kept inside a heterogeneous ...
A robot accepted by animals as conspecific is a very powerful tool in behavioral biology, particularly in studies of gregarious animals. In this paper we present the first results of acceptance of a robotic fish designed for experiments on collective animal behavior. The robot consists of two modules: ...
Argo is a global array of 3,000 free-drifting profiling floats that will measure the temperature, pressure and salinity of the upper 2000 m of the ocean. This will allow continuous monitoring of the climate state of the ocean, with all data being relayed and made publicly available within hours after ...
As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare. In this report, the 18S ...
