The authors highlight that stationary condition monitoring systems for high-voltage equipment is an essential prerequisite of the Smart-Grid implementation in the industrial electric networks. Diagnostic systems commissioning is relevant for network and electric furnace transformers of iron and steel works. The system operation performance is deteriorated because of lack of the methods intended for...
SAR-based image thresholding can be used to detect and map open water body locations and extents. The selection of a reasonable and consistent thresholding approach can be challenging across many complex landcover types. Besides SAR acquisition characteristics, environmental factors (e.g., emergent vegetation and wind-induced roughening of the water) can cause water locally increased backscatter relative...
The quality of water resources has a direct impact on the daily life of mankind and the sustainable development of society. However, with the rapid development of national industrialization, the current industrial wastewater discharge and improper handling have become more and more serious, especially for the growing domestic water pollution today, it is an urgent need for an efficient water quality...
This paper describes expert systems for the aquatic ecosystem diagnostics including its dynamics in the changing climate and detection of stressful situations when anthropogenic processes are realized in the sea basin. Expert system is based on the monitoring data processing and simulation results that are delivered by series models describing basic ecological, hydrological, hydrochemical and geophysical...
Electrical and control design of water conveyance facilities associated with hydroelectric projects including associated penstocks, valves, and gates are described in this guide. Guidance to plan and prepare designs is included. Installation, peration, or maintenance guideline and methodologies are not included. Design of new facilities and rehabilitation or replacement of existing facilities is covered...
The underwater images not only offer an interesting sight, but also have a challenge to monitor marine species and underwater activities. Taking a beautiful underwater image requires extraordinary equipment and technique. Usually, there are distorted colors on the image caused by poor light and water quality. So it requires an image enhancement process to get a proper photo to display. This research...
We present the Autonomous Microbiological Alert Sensor (AMAS), an automatic and remotely-controlled microbiology sensor for field Total Coliform (TC) and Escherichia Coli (E. coli) quantification at remote or difficult-to-access sites. Deployed directly in the environment like a floating buoy, the AMAS is fully waterproof and is capable to perform up to seven independent microbiological determinations...
Water is the basic element for human survival and development, and access to safe drinking water has been an important national goal in rural areas of China. In loess plateau regions of China, however, due to the drought climate, scarce water resources, backward economy and simple technology, the problem of drinking water safety has been seriously endangered the health of the people, and hindered...
Water masses with contrasting optical properties may reside in coastal zones. The shape of such easily recognizable patches and plumes change in time depending on currents and dynamics of specific ingredients, (mostly nutrients and resuspended matter). Based on a long-term (1966–2013) hindcast of currents, water fluxes in the semi-enclosed sub-basins of the Baltic Sea were reconstructed. Taking into...
There inevitably exists trace level of water in the SF6 insulated equipment. Previous research has shown that the decomposition characteristics of SF6 has close relationship with the moisture content. In order to study the influence of moisture under low volume fraction on discharge and decomposition characteristics of SF6. An experimental and testing platform for SF6 gas-insulated electrical equipment...
Water filling of carbon nanotube bores in the 4-15 nm diameter range is experimentally evaluated by means of tracking proton transport through a carbon nanotube membrane. A membrane with empty bores is installed between to reservoirs, one containing a significant concentration of free protons. Water fills nanotube bores allowing for voltage-motivated transport of protons from a region of high concentration...
Water Distribution Networks (WDN) are the infrastructures responsible for delivering drinking water to consumers. The effective monitoring and control of these systems is of vital importance since malfunction may significantly affect the health, safety, security and/or economic well-being of people. The advancements in coupling WDN with the ICT infrastructure, combined with the more recent introduction...
A Non-dispersive Infrared (NDIR) sensor for carbon monoxide (CO) was used to investigate the effects of physical and chemical factors on the accuracy of the sensor. The sensor's measurement range was 0.05 – 200 ppm. It was found that the measurement error of the NDIR at 50 ppm of CO was the lowest. Moreover, the increase of concentrations of the interferential gases (CO2, NO, NO2) led to the decrease...
During the past decade, water needs have risen exponentially to an unprecedented scale in India. The demand for water supply is ever increasing and satisfying this requirement has been a major challenge for many countries around the world. Urbanization, climatic changes and wasteful usage has further depleted the resource. Water being one of the major requirements for human survival, conservation...
Coastal water quality conditions have great influences on the ecological environment of tropical coastal regions. Conventional in-situ measuring approach is time consuming and laborious. The growing remote sensing data and techniques have become more widely used in estimating water quality parameters based on the reflection and absorption characteristics. The reflected spectral signals from the water...
Water is a natural resource that is very important. All living beings consume water, such as plants, animals, and humans. When the water is contaminated by pollutants it will damage the environment. More than that, it would have an impact on human health. Before consumption, the water must be guaranteed without pollutants. Conductivity is one of water quality parameters. High water conductivity showed...
In response to the call from the China Railway Corporation of the technology standardization construction of railway water supply and drainage monitoring system in our country, guarantee the prop-up function of railway water supply and drainage automatic monitoring system for railway water supply and drainage, feedback on the current situation of water supply and drainage automatic monitoring system...
Continuous Positive Airway Pressure Support (CPAP) devices are commonly used in Home Care for treating patients with sleep breathing disorders. This paper presents a Clinical Decision Support (CDS) model for adult patients with Obstructive Sleep Apnea, advising manual titration of positive pressure support and Oxygen supply. The CDS collects data from wireless devices, namely Arterial Oxygen Saturation...
Main stream of river changes frequently, and major trough swings often, which bring great danger and bad effects to the flood prevention and protection work even the regular life and property of local people. We take the Niyang River as an example, do deep research on the reasons why the main course in Bayi town changes frequently and the influencing factors. It reveals main mechanism of action of...
We show how THz time-domain spectroscopy can be used for the remote detection of an evolving gas phase mixture containing D2O and HDO and to characterize the reaction kinetics of: H2O + D2O → 2HDO.
