Classification selects one out of finitelymany classes based on available input and is applied to many kinds of application areas, e.g., diagnosis, monitoring, scoring, and pattern recognition. Often, classification is accomplished by use of Bayesian Networks which operate on evidence provided by sources, ...
Tidal flat plays an import role in purifying pollutants discharged from land and in providing marine products such as oyster and many kinds of shellfishes. Oyster in tidal flat usually has rough structures, causing a strong depolarization in microwave backscattering. The signatures can be detected using ...
The Fisheries Technology and Hydroacoustics Laboratory (TECPESQ-Institute of Oceanography, University of Rio Grande-IO-FURG-Brazil) has traditionally dedicated its working group to fish stock assessments using hydroacoustics. This technique allows the remote detection of organisms throughout the transmission ...
Ship detection is nowadays quite an important issue in tasks related to sea traffic control, fishery management and ship search and rescue. Although it has traditionally been carried out by patrol ships or aircrafts, coverage and weather conditions can become a problem. Synthetic aperture radars can ...
The Lagoon of Venice (LV) is a shallow lagoon located in the Mediterranean region, NE Italy. It is connected to the Adriatic Sea by three inlets. The LV is the largest Italian lagoon with an area of 550 km2, and is characterized by the presence of a complex occurrence of salt marshes, tide flats and ...
Thyroid hormones (T3, T4) have marked effect on body metabolism and in controlling osmoregulation activity in fish. The aim of this study was to determine the effect of water salinity changes on thyroid hormones level and thyroid-stimulating hormone (TSH) of grass carp. For this purpose 120 grass carp ...
A 24-year-old man was diagnosed with klinefelter’s syndrome (KS) and his wife was found to have an inversion on chromosome 9-46, XX, inv (9) (p11q21)- because of infertility. Intracytoplasmic sperm injection (ICSI) was performed for fertilization after fluorescence in-situ hybridization (FISH) was used ...
Gossypium mustelinum ((AD)4) is one of five disomic species in Gossypium. Three 45S ribosomal DNA (rDNA) loci were detected in (AD)4 with 45S rDNA as probe, and three pairs of brighter signals were detected with genomic DNA (gDNA) of Gossypium D genome species as probes. The size and the location of ...
Background Clonorchiasis caused by ingesting improperly prepared fish ranks among the most important but still neglected food-borne parasitic diseases, especially in the People’s Republic of China (P.R. China). To promote the implementation of interventions efficiently, the demonstration of an epidemiological ...
Conservation efforts to increase duck production have led the United States Fish and Wildlife Service to restore grasslands with multi-species (3-5) mixtures of introduced cool season vegetation often termed dense nesting cover (DNC). The effectiveness of DNC to increase duck production has been variable, ...
We used antisense morpholino oligonucleotide technology to knockdown leptin-(A) gene expression in developing zebrafish embryos and measured its effects on metabolic rate and cardiovascular function. Using two indicators of metabolic rate, oxygen consumption was significantly lower in leptin morphants ...
This paper proposes an improved Artificial Fish Swarm Algorithm (AFSA) to deal with the two-dimensional non-guillotine cutting sock problem. The visual field enlarges gradually according to the iteration. A similar Bottom Left algorithm is used to map the cutting pattern to the actual layout. The simulation ...
Power allocation was a key technique that could significantly improve the performance of radio access networks. But in the centralized, collaborative, cloud-based and clean radio access network(C-RAN), there were few power allocation algorithms proposed in it. In this paper, we established an optimization ...
The present work relates to detection of the freshness of fish by using electronic nose composed of 8 metal oxide sensors. The advantages of the decision tree structure are applied to evaluate fish freshness by selecting both classification algorithm and extracted features in every node of the decision ...
Since the introduction of marine economy strategy, the interaction and economic correlation between marine economy and land industry are rising increasingly. The paper analyzes the functions performed by marine industry on industrial structure system and the spatial restraints of correlation between ...
This study presents a novel technique for the measurement of insertion depth of an epidural Tuohy needle in real-time. A wireless camera is used which transmits video images during insertion to a host computer. The computer contains the image processing algorithm to detect the visible needle in the ...
Fixed autonomous acoustic recording devices(autonomous recorders [ARs]) are defined as any electronic recording system that acquires and stores acoustic data internally (i.e., without a cable or radio link to transmit data to a receiving station), is deployed semi-permanently underwater (via a mooring, ...
The objective of this research is to determine the suitability of Worldview-2 high resolution multispectral data in classifying and mapping benthic habitats, specifically seagrass. Worldview-2 offers an increased number of spectral bands for high-resolution image, from the traditional 4bands to 8 bands. ...
One of the main species in the Caribbean cost of Yucatan-Mexico is the Mero (Epinephelus striatus), but the fisheries are beginning to go down and the principal reason could be the over-catch. The objective of this work is to study the aggregations of the Nassau Grouper, as well as the rest of the fish ...
It is necessary to refine the acoustic estimation method applied in the Gulf of California, especially regarding the acoustic energy allocation to the different species coexisting in the same area, in order to produce a more precise and reliable fishery independent biomass index for the sustainable ...
