Border detection in digital images: An approach by fuzzy numbers
(2007-12-01)
The purpose of this paper is to introduce a new approach for edge detection in gray shaded images. The proposed approach is based on the fuzzy number theory. The idea is to deal with the uncertainties concerning the gray ...
Structural and optical properties o plasma-deposited a-C:H:Si:O:N films
(2021-01-01)
Thin a-C:H:Si:O:N films were deposited from plasmas fed hexamethyldisiloxane, oxygen and nitrogen, and characterized as a function of the partial pressure of oxygen in the feed, Rox. Deposition rates varied from 10 to 27 ...
Distribution Systems Resilience Improvement Utilizing Multiple Operational Resources
(2021-01-01)
This paper presents a strategy based on mixed-integer linear programing (MILP) model to improve the resilience in electric distribution systems (EDSs). The restoration process considers operational resources such as the ...
Cerebellar tomographic attenuation of healthy felines
(Univ Federal Rural Pernambuco, 2011-12-01)
The cerebellum is responsible for coordination and maintenance of the fine control of muscle contraction. In cases of a suspected cerebellar disorder, a computed tomography scan can be performed to identify structural ...
Shifting Sands in a CO2 Desert: Replacing Extracted CO2 with By-product CO2 for Use in Enhanced Oil Recovery
(Elsevier B.V., 2014-01-01)
Efforts to sequester or otherwise manage carbon dioxide emissions on a large scale will require an improved understanding of the geospatial characteristics of anthropogenic CO2 sources. Recent work by the authors using ...
