International Classification:

G01V 1/30
G01V 1/28

Abstract:

Methods and devices use improved FWI techniques for seismic exploration of subsurface formations including salt bodies using a travel-time cost function. In calculating the travel-time cost function, time-shifts may be weighted using cross-correlation coefficients of respective time-shifted recorded data and synthetic data generated based on current velocity model. The improved methods enhance the resulting image while avoiding cycle-skipping and issues related to amplitude difference between synthetic and recorded data.

Abstract:

Discussed herein are methods of orienting one-dimensional and two-dimensional materials via the application of stationary and rotating magnetic fields. The oriented one-dimensional and two-dimensional materials may exhibit macroscopic properties, and may be employed in various measurement devices as well as thermal and electrical shielding applications or battery devices. A single 1D or 2D material may be suspended in another material such as dionized water, polymer(s), or other materials during the orientation, and the suspension may remain as a liquid or may be solidified or partially solidified to secure the oriented material(s) into place. The 1D and 2D materials that respond to the magnetic orientation may further cause other elements of the suspension to be oriented in a similar manner.

International Classification:

F15D 1/02
G10K 11/34
G10K 15/04

Abstract:

Disclosed is a system including a substrate having a first side and a second side and a layer of photoacoustic material disposed on the first side of the substrate. The layer of photoacoustic material is configured to generate a directional ultrasound wave in response to a laser beam impinging on the layer. A conduit may be coupled to the housing and have an opening adjacent to the layer of photoacoustic material; the directional ultrasound wave may be directed through fluid that is contained in the conduct to generate a liquid jet in a liquid.
