Abstract: The present disclosure relates to sustainable and green polylactic acid-based membranes embedded with self-assembled positively and negatively charged multiwalled carbon nanotube/graphene oxide nanohybrids for the removal of organic and inorganic nutrients from wastewater, and methods of synthesis of the same. A positively charged multi-walled carbon nanotube/graphene oxide (f-MWCNT/GO) nanohybrid-based mixed matrix membrane can comprise a self-assembled multi-walled carbon nanotube and graphene oxide (f-MWCNT/GO) nanohybrid, and a polylactic acid (PLA) membrane matrix. The f-MWCNT/GO nanohybrid is integrated into the PLA membrane matrix to form the positively charged mixed matrix membrane. A negatively charged multi-walled carbon nanotubes (f-GO/MWCNTs-COOH) nanohybrid-based mixed matrix membrane can comprise a positively charged Graphene Oxide and negatively charged multi-walled carbon nanotube-COOH (f-GO/MWCNTs-COOH) nanohybrid, and a polylactic acid (PLA) membrane matrix.

Abstract: A method for estimating a range of a moving target includes emitting, from a target, a first ultrasound signal T, wherein the first ultrasound signal T is generated based on a first differential Zadoff-Chu sequence x; receiving, at a receiver, a second ultrasound signal R, which corresponds to the first ultrasound signal T, wherein the second ultrasound signal R includes a second differential Zadoff-Chu sequence y; applying a maximum likelihood estimator to the first ultrasound signal T and the second ultrasound signal R to calculate an initial time of flight estimate taucorr; and calculating an initial range estimate dcorr of the target by multiplying the initial time of flight estimate taucorr with a speed of sound c. A differential Zadoff-Chu sequence is different from a Zadoff-Chu sequence.

Abstract: Improved methods and systems for hydrocarbon production, including operations involving ballooned hydraulic fractures and complex toe-to-heel flooding. The recovery of ballooned hydrocarbons via ballooned hydraulic fractures can include the use of an OZF (Optimized Modified Zipper Frac) that recovers hydrocarbons. OZF can be implemented as a fracturing technique with respect to organic shale reservoirs to maximize near-wellbore complexity and overall permeability and hydrocarbon recovery. Additionally, Complex toe-to-heel flooding (CTTHF) can be applied to horizontal wells. CTTHF uses one or more barriers and an injector hydraulic fracture, and facilitates the control of early water production.

Abstract: Applying shock waves using a plasma pulse generation system or other comparable systems, including an acoustic/pressure oscillatory system, would help to enhance the complexity of the far field hydraulic fracture during fracturing shale formation. It would also help in avoiding pre-mature screen out. The critical factor to maximize the desired results is to apply the shock waves at the correct time. By combining shock wave technology with the newly developed fracturing pressure data analysis, it is possible to achieve maximum results.

Abstract: In an example diagnostic fracture injection test (DFIT), or a “minifrac,” a fracturing fluid is pumped at a relatively constant rate and high pressure to achieve a fracture pressure of a subterranean formation. Sometime after achieving formation fracture pressure, the pump is shut off and the well is shut in, such that the pressure within the sealed portion of the well equilibrates with the pressure of the subterranean formation. As the pressure declines, the pressure of the injection fluid is monitored. This collected pressure data is then used to determine information regarding the permeability of the subterranean formation. In some implementations, a model for before closure analysis (BCA) can be used to estimate the permeability of a formation based on before closure pressure data (i.e., data collected before the fracture closure pressure is reached) based on a solution to the rigorous flow equation of fracturing fluid, which is leaking off into the formation during fracture closure.

Abstract: In one example embodiment, a mobile computing device provides assistance services for visitors at events which involve large crowds and long distances. The mobile computing device may be used to read a unique identifier for a visitor from an identification token for the visitor. The mobile computing device may then send visitor location data for the current location of the visitor to a remote command center. The mobile computing device may then receive leader location data from the remote command center. The leader location data may identify a last known location for a leader of a group of visitors that includes the visitor. After receiving the leader location data, the mobile computing device may compute directions from the current location of the visitor to the last known location of the leader, and the mobile computing device may display those directions on a map. Other embodiments are described and claimed.

Abstract: The invention provides methods for performing the appropriate manipulation of pressure-time data during a hydraulic fracturing treatment or test to determine the condition of the created fracture. The mode of growth, dilation, or intersection with one or more natural fractures may be determined accurately and quickly. The methods include the steps of acquiring fracturing data, assessing the fracturing index based on a moving reference point, and establishing the mode of fracture propagation using the fracturing index. The methods provide for the determination of the time of intersection of a hydraulic fractures with one or more natural fractures. The methods also provide for an early warning of sand-out possibility. The data analysis may be performed in real time during the progress of the treatment or test or in a playback mode after the completion of the treatment or test.
