    Abstract: The present invention provides a method of hydraulically fracturing a well penetrating an subterranean formation by optimizing the spacing of fractures along a wellbore to form a complex network of hydraulically connected fractures by identifying a deviated wellbore in a subterranean formation; introducing a series of fractures in the deviated wellbore, wherein the series of fractures comprising at least a first fracture, a second fracture, a third fracture and a fourth fracture each separated by a non-uniformed and an increased spacing distance such that the spacing distance from each adjacent fracture in the series of fractures is at an increased distance; and forming one or more complex fractures extending from the series of fractures to form a complex fracture network.

    Abstract: Diagnostic tool for eye disease detection using a smartphone. At least some of the example embodiments are methods including capturing, by way of a camera lens on a device, an image of an eye to create a raw specimen; processing the raw specimen to create a processes specimen; performing edge detection on the processed specimen to detect a boundary of a cornea; extracting a region of interest of the cornea; identifying a boundary of the region of interest using a boundary tracing technique to identify a second boundary; analyzing the second boundary of the region of interest, by measuring a slope of the second boundary; and classifying the region of interest as including an eye disease, based on the analyzing the second boundary.
