A Fitted Fuzzy-rough Method for Missing Data Imputation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Missing data imputation is a fundamental task for reducing uncertainty and vagueness in medical dataset. Fuzzyrough set has taken very important role to accurate representation original information. This paper proposes ...
The research on detection of crop diseases ranking based on transfer learning
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Crop diseases are a major global threat to food security. Because the lack of agriculture experts or necessary facilities, it is difficult to determine the type of disease, as well as the degree of disease in time, which ...
Digital heritage enrichment through artificial intelligence and semanticweb technologies
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Art and culture represent substantial ways to transfer the history of humans across civilizations and epochs. Preserving artwork and cultural objects is thus important and the focus of multiple institutions and governments ...
A Modified Layer of Protection Analysis for Cyber-Physical Systems Security
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Layer of Protection Analysis (LOPA) is the most commonly used approach for quantitative safety risk assessment in the process control industry to protect a Cyber- Physical System (CPS) from accidental hazards-causing ...
Pore-scale mechanisms associated with permeability impairment in porous media: A micromodel study
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Recently, researchers are attracted towards the gas production from hydrate bearing sediments considering its abundance in marine continental margins and persisting demand for alternate energy. Dissociation of hydrate into ...
Impact of fines type on gas flow using 3D micro-computed tomography
(
Society of Petroleum Engineers
, 2019 , Conference Paper)
Methane hydrates are promising unconventional energy source with natural reserves above 1,000 Trillion m3. Hydrates are found in saturated sandy sediments, where multi-phase flow of gas takes place through sediment's pores, ...
Hydrate surface area measurements during dissociation using dynamic 3d synchrotron computed tomography
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Availability of natural hydrates and ongoing rise in demand for energy, motivated researchers to consider hydrates as a potential energy source. Prior to gas production operations from hydrate-bearing sediments, hydrate ...
Pore networks to characterize formation damage due to fines at varied confinement and sand shape
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Carbon sequestration in geological formations is in demand for many applications, especially energy production from hydrates. During gas production in a sandy hydrate reservoir, two phase flow and changes in confinement ...
Grouping minimum REV of porosity and tortuosity based on descriptors of sand grains
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
In sandy reservoirs, selecting a representative elementary volume (REV) for the pore scale, is essential for predictive upscaling toward the reservoir scale. The porosity and tortuosity of a sand media are used for REV ...
Identifying the key performance challenges to achieve improved export performance for Qatari SMEs
(
Elsevier
, 2019 , Conference Paper)
Small and medium enterprises in Qatar, similar to their counterparts in other emerging countries, face many challenges by entering international markets. This study aims to identify and analyze the key performance challenges ...
