Mobile wireless sensor networks applied to the survey of water infrastructures
(
IEEE
, 2010 , Conference Paper)
The paper reports our last advances in the realization of mobile wireless sensor networks (WSNs), able to reveal unknown tracks and leakages within underground pipelines used to distribute water. This WSN technology is ...
Joint optimal threshold-based relaying and ML detection in cooperative networks
(
IEEE
, 2012 , Article)
This paper proposes two detection schemes for cooperative networks comprising a source, a relay and a destination. The relay is assumed to operate in a half-duplex mode and it employs decode-and-forward (DF) relaying. The ...
Vibration suppression in metastructures using zigzag inserts optimized by genetic algorithms
(
Springer New York LLC
, 2017 , Conference Paper)
Metastructures are known to provide considerable vibration attenuation for mechanical systems. With the optimization of the internal geometry of metastructures, the suppression performance of the host structure increases. ...
Arabic handwriting recognition using sequential minimal optimization
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Due to the variability of writing styles and to other problems related to the nature of Arabic scripts, the recognition of Arabic handwriting is still awaiting accurate results. Segmentation of Arabic handwritten words ...
Characteristics-based model predictive control of selective catalytic reduction in diesel-powered vehicles
(
Elsevier Ltd
, 2016 , Article)
In heavy-duty diesel exhaust systems, selective catalytic reduction (SCR) is used to reduce NOx to nitrogen to meet environmental regulations. Diesel exhaust after-treatment involves a set of components that are best ...
Optimal utilization of geothermal heat from abandoned oil wells for power generation
(
Elsevier Ltd
, 2019 , Article)
Unlike other types of renewable energy, geothermal resources represent a stable energy source because they can be exploited regardless of meteorological conditions. In geothermal systems, heat is exchanged between the ...
A mathematical model for carbon fixation and nutrient removal by an algal photobioreactor
(
Elsevier Ltd
, 2016 , Article)
A comprehensive mathematical modeling method for Chlorella vulgaris (Cv) has been developed to assess the influence of nutrient concentration (total nitrogen TN= 28-207 and total phosphorus TP= 6-8mgL 1) and irradiation ...
Real-time cooperative data routing and scheduling in software defined vehicular networks
(
Elsevier B.V.
, 2022 , Article)
Links in vehicular networks are highly dynamic and generally exist only for a limited amount of time. Moreover, data packets are generally transmitted over multiple hops and have diverse latency requirements. The above ...
Koh-based modified solvay process for removing na ions from high salinity reject brine at high temperatures
(
MDPI
, 2021 , Article)
The traditional Solvay process and other modifications that are based on different types of alkaline material and waste promise to be effective in the reduction of reject brine salinity and the capture of CO2 . These ...
Magnesium recovery from desalination reject brine as pretreatment for membraneless electrolysis
(
Elsevier B.V.
, 2022 , Article)
Alkali-earth metals pose a significant challenge to water treatment technologies and electrochemical processes due to their propensity to precipitate as metal hydroxides, which can deposit on membranes and/or electrodes ...
