The article based on the fuzzy matter-element method to build index system, which including rural economic environment, logistics capability and logistics potential, the three elements and its subordinate 16 indicators, then make a comprehensive evaluation of logistics capability of rural areas in Hebei ...
The Pasquotank River Watershed is found in Northeast North Carolina beginning in the Great Dismal Swamp at the Virginia/North Carolina border and flows into the Albemarle Sound. The watershed provides a transition between spawning grounds and the waters of the Albemarle Sound. The sound serves as a ...
This paper presents a smart energy management strategy (SEMS) to optimise the economic operation of a micro-grid. As an important component of smart grids, the micro-grid acts as a bridge to bundle renewable generation, energy storage systems (ESSs) and electric vehicles (EVs) together. It can be operated ...
The independent component analysis with reference algorithm uses gradient method to optimize the cost function, this makes it easily fall into local optimal solution. To overcome the problem, this paper proposes a new independent component analysis with reference algorithm that has global convergence. ...
Presents the introductory editorial for this issue of the publication.
Advances in information and communication technologies are facilitating a shift from infrastructure business to service business. Service business engineering is still in its infant stage. Lessons learned from business model engineering on the scale of tens of millions of mobile users provide clues ...
The detection of ships at sea is a difficult task made more so by uncooperative ships, especially when using transponder-based ship detection systems. Synthetic aperture radar (SAR) imagery provides a means of observation independent of the ships cooperation, and over the years, a vast amount of research ...
Sentiment analysis functions by analyzing and extracting opinions from documents, websites, blogs, discussion forums and others to identify sentiment patterns on opinions expressed by consumers. It analyzes people's sentiment and identifies types of sentiment in comments expressed by consumers on certain ...
Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be ...
The jack mackerel population has been assessed directly by fisheries acoustics without consider the day-night fish school behavior. In this paper the day-night effect on spatial structure of Jack mackerel is analyzed from fisheries acoustics surveys. The diel behavior of fish schools was assessed by ...
Droughts have been recorded all across Canada and have had significant impacts on individuals and communities. With climate change, projections suggest an increasing risk of drought in Canada, particularly in the south and interior. However, there has been little research on the impacts of drought on ...
From 15 to October 24, 2013, the second hydroacoustic survey cruise T13-10-02P aboard the B/I Tohalli, made with emphasis on small pelagic fish in the Gulf of Guayaquil was ejecuted. The biomass estimated was Auxis thazard 121.976 t, Scomber japonicus 70.818 t, Decapterus macrosoma 23.894 t and Opisthonema ...
The austral sardine (Sprattus fuegensis) is the target fish resource of a small-scale fishery operating in the Patagonian waters of Chile (41°30'S-46°00'S). Purse seine boats composed the fleet and landings have fluctuated between 14,344 and 48,589 tons during the period between 2006 and 2014. The stock ...
The Brazilian sector of the Pelotas Basin (PB) covers an area of 210,000 km2, limited northwards by the Florianópolis High southwards by the boundary with Uruguay. The PB is economically and strategically important due to the presence of sub-surface mineral resources such as oil, natural and hydrate ...
In this work scientific echosounder were used hull mounted onboard R/V Marion Dufresne II to scrutinize the vertical distribution of micronekton according to water masses characteristics along transect which were discriminated with spatial remote sensing data. Acoustic data were collected continuously ...
Various marine lives are mainly cultured from fish farms. This study focused on the abalone among many marine lives to research on the underwater monitoring system which monitors its growth and development and the amount of sludge. The insufficient feeding in the farm causes growth inhibition of abalone ...
The Peruvian ""anchovy"" (Engraulis ringens) maintains the world's largest single species fishery in the world. Acoustic data from research cruises surveying the distribution area of this species provide meaningful information about its behavior and distribution as well as its abundance within years ...
Timing synchronization is essential in cases where multiple sensor nodes with ultrasonic sensors are deployed in the same place. This is because ultrasonic sensors should be powered at a precise timing so as to prevent ultrasonic interference. A harmful-birds scaring system utilizing a new timing-synchronization ...
With the fast motion and rapid population increase in the World, feeding of the population has become an important problem. In 1500s, the world population was less than 1 billion while it reached 2.5 billion in 1900 and 7 billion in 2015. In the last century, the world population increase has exploded ...
Human-induced changes to habitats can have deleterious effects on many species that occupy them. However, some species can adapt and even benefit from such modifications. Artificial reefs have long been used to provide habitat for invertebrate communities and promote local fish populations. With the ...
