Well-Test Interpretation Model of Water-Injection Well in a Low-Permeability Reservoir and Its Application

open access: yesEnergies
For low-permeability reservoirs, water-flooding development is usually adopted, which leads to induced fractures near the wellbore, increasing reservoir heterogeneity, and making water-flooding development more complex.

Estimation of body weight from the base of gait and the area swept in one stride—forensic implications

open access: yesEgyptian Journal of Forensic Sciences, 2018
Background Forensic gait analysis is a new discipline in forensic sciences but gaining popularity worldwide. CCTV camera footages from the scene of a crime can reveal a great detail about the perpetrator, and gait is one of them.

Potential biomass and distribution of octopus in the eastern part of the Campeche Bank (Yucatán, Mexico)

open access: yesScientia Marina, 2020
The octopus fishery on the Campeche Bank (Yucatán, Mexico) is considered the third largest in the world. In Yucatán, two fleets target this resource: an artisanal fleet and a semi-industrial fleet. The artisanal fleet only catches Octopus maya, while the

Opportunities for and challenges to further reductions in the “specific power” rating of wind turbines installed in the United States [PDF]

open access: yes, 2021
A wind turbine’s “specific power” rating relates its capacity to the swept area of its rotor in terms of Watt per square meter. For a given generator capacity, specific power declines as rotor size increases.

Research on the integrated calculation method of current recovery and limited recovery in tight sandstone gas reservoirs

open access: yesFrontiers in Earth Science
Considering the differences in reserves and their utilization among gas reservoir area, utilization area and swept area, a reserves zoning producing model was established, and a method for integrating current recovery and limited recovery in gas ...

IMPLEMENTATION OF TRANSONIC AREA RULE AND SWEPT BACK DELTA WING DESIGN ON AN AIRCRAFT.

open access: yesGraduate Research in Engineering and Technology, 2022
The transonic area rule was first implemented in the 1950s. It is an important concept related to the drag on an aircraft or other body in transonic and supersonic flight which states that two airplanes with the same longitudinal cross-sectional area distribution have the same wave drag, independent of how the area is distributed laterally.
