Real Time Wireless Monitoring and Control of Water Systems Using Zigbee 802.15.4

In this paper we have shown how to monitor the water level of water systems such as water tanks, rivers, ground water table, and bore wells remotely. We have also shown that how to control the working of pump automatically and remotely. It can also be used to remotely monitor the flood areas wirelessly ...

Effect of source-drain metal shield in FET structure on drain leakage current

This study presents the effect of source-drain metal shield in FET structure on drain leakage current. The FET structure was fabricated on the wafer by using MIMOS's standard fabrication process. Aluminum (Al) was sputtered with thickness of 400 nm as metal shield layer at the source and drain area ...

Detecting abnormal fish trajectories using clustered and labeled data

We propose an approach for the analysis of fish trajectories in unconstrained underwater videos. Trajectories are classified into two classes: normal trajectories which contain the usual behavior of fish and abnormal trajectories which indicate the behaviors that are not as common as the normal class. ...

Classification of environmental microorganisms in microscopic images using shape features and support vector machines

Environmental Microorganisms (EMs) are currently recognised using molecular biology (DNA, RNA) or morphological methods. The first ones are very time-consuming and expensive. The second ones require a very experienced laboratory operator. To overcome these problems, we introduce an automatic classification ...

Marine observation framework using ICT for mariculture in Indonesia

According to The State of World Fisheries and Aquaculture 2012, a publication of the Food and Agriculture Organization of the United Nations, five Asian nations topped the world ranking of mariculture producers in 2010. In order, they were China, India, Vietnam, Indonesia, and Bangladesh. Asia's maricultural ...

Human use characterization and visualization in marine spatial planning efforts in the Northeast

Comprehensive ocean planning must account for the diversity of human uses that converge in coastal waters and their potential impacts on marine ecosystems. Ocean plans have been developed at the federal, regional, and state level to address these issues; however, the under-documentation of human activities ...

Hypoxic intrusions to Puget Sound from the ocean

Oceanic intrusions of dense, hypoxic water regularly occur at the entrance to Puget Sound, WA (USA), and may be significant to regional dissolved oxygen levels. Seabed observations at Admiralty Inlet from 2009 to 2013 show a strong correlation of low dissolved oxygen concentrations with high salinity, ...

Brushless DC motor control system based on submarine hybrid transmission technology

The energy and data hybrid transmission technology is one of the most important technologies in the field of submarine investigation and exploitation. It is urgent to study high-power and high-speed hybrid transmission technology. All kinds of submarine equipments, using electric motor to drive the ...

Mini-ROVs, going where no ROV has gone before

Mini-ROVs have been accepted as a mainstream tool and the demand for them has increased rapidly. This success may be attributed to excellent ease of use, the availability of advanced new capabilities and an attractive price/performance ratio.

[Front matter]

Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank ...

Strategies to Minimize Antibiotic Resistance

Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs) and various data such as pharmacokinetic (PK) and pharmacodynamic (PD) properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST), clinical ...

Antigen processing and presentation: Evolution from a bird's eye view☆

Most detailed knowledge of the MHC outside of mammals has come from studies of chickens, originally due to the economic importance of the poultry industry. We have used our discoveries about the chicken MHC to develop a framework for understanding the evolution of the MHC, based on the importance of ...

The effect of gamma irradiation on astaxanthin synthetase encoding gene in two mutant strains of Phaffia rhodozyma

Background and Objectives Astaxanthin, an orange-red carotenoid pigment, acts as a protective agent against oxidative damage to cells in vivo. The astaxanthin synthetase gene (crtS) size consists of 3995 bp. This gene has been suggested to catalyse β-carotene to astaxanthin in Phaffia rhodozyma. The ...

Effect of zinc oxide nanoparticles on viability of human spermatozoa

Background: The extensive use of different nanoparticles has raised great concerns about their occupational and biological safety. Objective: The aim of this study was to evaluate the cytotoxic effect of zinc oxide nanoparticles (ZnO NPs) on viability of spermatozoa. Materials and Methods: Semen samples ...

Decision support system for increasing sustainable productivity on fishery agroindustry supply chain

The objective of this research was to develop a decision support system (DSS) for increasing sustainable productivity on fishery agro industry supply chain management. The DSS is able to provide information and decision alternatives to all stakeholders related to catching business, added value, agro ...

Chasing fish: Tracking and control in a autonomous multi-vehicle real-world experiment

This paper describes scientific and engineering efforts towards remote sensing, tagging and continuous tracking of sunfish specimens (Mola mola, world largest bony fish) in the open sea. This ongoing experiment is done in the context of a collaboration between MBARI and Porto University and bridges ...

Development of the three-dimensional visualization method for the inner structure of small size fish using 25 MHz acoustic profile measurement

Visualization method using ultrasonic acoustic profile measurement was introduced and inner structures of small size fishes were examined. Detection of external and internal body surface were executed. Two kinds of fishes are chosen in this experiment and measured by using 25 MHz medical probe. Then ...

Development and sea trials of a new Camera-Based Assessment Survey System for reef fish stocks assessment

A new towed camera system, known as the Camera-Based Assessment Survey System (C-BASS), is being developed for reef fish stock assessments. This system has the capability of facilitating large-scale quantitative assessments and allows fisheries scientists to enumerate economically important reef fishes ...

SPLASSH (Student Programs Like Aquatic Science Sampling Headquarters) http://splassh.meteor.com a socially driven platform about water

Student Programs Like Aquatic Science Sampling Headquarters (SPLASSH) is a social network for investigating, sharing, and visualizing data involving water. SPLASSH is designed around the Meteor.js web framework, which builds upon Comet technology to push, or deliver content from the server to end-users ...

Specialized tools for biological assessment using split beam hydroacoustics

The science of fisheries acoustics and its applicability to resource management have evolved over the past several decades. The use of hydroacoustics for the assessment of fisheries resources is well established and split beam echosounders are now the standard instrument of scientific fisheries acoustics. ...
