Displacement efficiency of faults and fractures

Journal of Structural Geology, 1987
Abstract Faults and fractures evolve kinematically as Somigliana dislocations. As a result, displacement gradients are always present, with displacements reducing to zero at fault/fracture tips. We present a graphical method for the comparison of displacement gradients from fractures of various magnitudes and types. Displacement efficiency of a fault/

Time and Memory Efficient Displacement Map Extraction

ACM SIGGRAPH 2021 Talks, 2021
Displacement maps are used to enhance the final rendered animation at most high-end studios including Blizzard Entertainment. However, commonly available products (Mudbox, Zbrush) that are used to sculpt high resolution models and extract displacements from low resolution counterparts are not conducive for quick iterative workflow that artists normally

Efficient skeleton-guided displaced subdivision surfaces

Multimedia Tools and Applications, 2017
Displacement mapping is a computer graphics technique that uses scalar offsets along normals on a base surface to represent and render a model with highly geometric details. The technique natively compresses the model and saves memory I/O. A subdivision surface is the ideal base surface, due to its good geometric properties, such as arbitrary topology,

Efficiency of displacement estimation techniques

Signal Processing: Image Communication, 1997
Abstract An analytical description of displacement estimation which allows an objective evaluation and comparison of various displacement estimation techniques is presented. For evaluation and comparison rate-distortion functions are calculated and by this the impact of the 2D motion model of the displacement estimator and the amplitude and spatial ...

30 % higher efficiency with 50 % less displacement

MTZ worldwide, 2010
How can one discover the full potentials of downsizing internal combustion engines? Mahle addressed this issue with a technology demonstrator, a 1.2-l three-cylinder spark-ignition engine, which the company presented to the public three years ago.

Displacement damage efficiency in sapphire

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992
Abstract The efficiency of point defect production in sapphire by a variety of ion beams has been estimated by monitoring the oxygen vacancy colour centre concentration. Results are presented for H, D, He, B, N, Ne, Ar and Kr bombardment at both room temperature and 77 K.

Displacement flows in eccentric annulus : methods to improve displacement efficiency

2022
This thesis presents a study of displacement flows in highly deviated and horizontal eccentric annuli with the objective of increasing the displacement efficiency. The motivation for studying these types of flows comes from primary cementing, where a sequence of fluids is pumped into the well to displace in-situ drilling mud and to provide a hydraulic ...

Optimization of Displacement Efficiency During Primary Cementing

Latin American and Caribbean Petroleum Engineering Conference, 1997
Abstract Different philosophies exist for how to design cementing jobs in order to achieve the best possible displacement. This is due to the fact that the process is complex and that it often is difficult to measure the degree of displacement in a well.

Efficient Multidriven Strand Displacement Reaction for Biosensing

Analytical Chemistry
A key challenge for achieving high-efficient DNA strand displacement reaction (SDR) with existing technologies is the inferior kinetic performance due to the alternately cumbersome conjunction and dissociation of dsDNA. In this work, a novel multidriven SDR collaborated by toehold initiator, strand towing, and click chemistry is engineered.

Effect of Interfacial Tension on Displacement Efficiency

Society of Petroleum Engineers Journal, 1966
Abstract Immiscible displacement tests were performed in a consolidated sandstone core over the interfacial tension range from less than 0.01 to 5 dynes/cm to better define how interfacial tension (IFT) reduction can lead to increased oil recovery.
