We propose a nonparametric predictor and a supervised classification based on the regression function estimate of a spatial real variable using k-nearest neighbors method (k-NN). Under some assumptions, we establish almost complete or sure convergence of the proposed estimates which incorporate a spatial ...
The Automatic Identification System (AIS) was established as a cooperative system for maritime surveillance, collision avoidance and combating illegal fishery. However, violations of AIS regulations need to be identified by independent sensors. This paper investigates possibilities for joint evaluation ...
As an important fishery in China, the changes of marine hydrological elements have seriously affected the development of Zhoushan. The spatio-temporal pattern evolution of marine hydrological elements and the response of marine hydrological elements and El-Nino in Zhoushan sea area are analyzed in this ...
As the carrier of economic activities, land resource is an indispensable production factor of economic development. Economic growth leads to increased demand for land and changes in land utilization form. Therefore, changes in land use and land cover can reflect regional economic development situations ...
The Ministry of Agriculture, Forestry and Fisheries (MAFF) in Japan spends about 7 billion yen in commissioned project studies and competitive funds programs that are mainly targeted at maturing technology from a technology readiness level in the 3–6 range. The success rate of these programs, as measured ...
This study details the development of an ‘underwater glider with a density-difference-engine’ for the use of oceanographic survey, monitoring the marine environment, fisheries, ocean exploration, and marine sports/leisure activities. The underwater glider presented here is unique, in that it incorporates ...
Abstract Iodine, a dynamic nutrient present in thyroid hormones, is responsible for regulating thyroid function, supporting a healthy metabolism, and aiding growth and development. Iodine is also essential for brain development during specific time windows influencing neurogenesis, neuronal and glial ...
Background: Given a shortage of construction workers, it is important to develop strategies to avoid early retirement caused by cardiovascular diseases in Hong Kong. Objectives: (1) to describe the cardiovascular health of construction workers in Hong Kong, (2) to examine the demographic differences ...
ABSTRACT Background A detailed description of anthropometric and physiologic characteristics of persons in different diet groups is lacking. Objective We aimed to perform cross-sectional analyses of diet group with anthropometric and physiologic characteristics in a large cohort in the United Kingdom. Design The ...
Background Paraspeckles are subnuclear bodies assembled on a long non-coding RNA (lncRNA) NEAT1. Their enhanced formation in spinal neurons of sporadic amyotrophic lateral sclerosis (ALS) patients has been reported but underlying mechanisms are unknown. The majority of ALS cases are characterized by ...
For many years, the maximum swimming speeds of dolphins have been reported almost entirely through observations. The objective of this paper is to estimate the swimming speed of dolphins using a theoretical analysis and numerical method. The FLUENT software solver and User Defined Function (UDF) dynamic ...
ACCORDING TO THE International Union for the Conservation of Nature (IUCN) 67,222 species of animals, of which 5,674 are mammals, are on its ‘red list’ of endangered species — fish and birds are the most heavily hit. Of these, 1,337 (109 mammals) are already either extinct, possibly extinct or extinct ...
Malachite green (C23H25ClN2) is an illegal fungicide of aquatic products due to its potential carcinogenic, teratogenic, and mutagenic effects. It is typically challenging to detect C23H25ClN2 in fish with conventional techniques. The study reported a simple and rapid method for detecting C23H25ClN2 ...
Alternative routes of the Russian section of the Nord Stream 2 gas pipeline were studied using environmental criteria. The planned anthropogenic impact was assessed making use of a complex of biotic and abiotic parameters of marine ecosystems allocated in the zones of influence. On land the water protection ...
A seaport is a dynamic environment which plays a crucial role in the global economy. It includes various activities such as transportation, logistic, fishing, rescue operations and protection of the environment against its destructive impacts that make tremendous challenges. In this paper, we investigate ...
The transport of perishable goods like horticultural products and fish has been a major problem due to the lack of refrigeration in transit vehicles resulting in produce going bad thus losses and also leads to reckless over speeding which causes accidents. Those equipped with refrigeration facilities ...
Determination of injury rate on fish surface is one of the major cause for increasing quality of fish on the markets. Detecting injury fishes manually is hard work with low efficiently. An image processing method is usually considered to do this work as an online selecting method of injury area. The ...
Nowadays there is a growing interest to the natural evolutionary changes and especially those driven by environmental pollution and climatic variations. Climate change in combination with human activities largely influences the environment and especially aquatic ecosystems. We develop an approach for ...
In the natural world, many social species amplify their collective intelligence by forming real-time closed-loop systems. Referred to as Swarm Intelligence (SI), this phenomenon has been rigorously studied in schools of fish, flocks of birds, and swarms of bees. In recent years, technology has enabled ...
Many studies on mercury contamination in aquatic biota deal with the effect of consuming metal-contaminated organisms on human health. In this study, we examined the factors that cause mercury contamination in Podocnemis unifilis in the Xingu River Basin of Mato Grosso and Pará States, Brazil. We quantified ...
