Bursting for enhanced ablation of materials
SPIE Proceedings, 2014A significant enhancement in the rate of material removal is demonstrated using a nanosecond-pulsed UV fiber laser in multi-pulsing burst mode, as compared to the case without bursting. Percussion drilling and scribing of thin-film and bulk material tests show that, in general, laser bursts with increased pulse count and reduced pulse spacing show ...

Material-Driven Resolution Enhancements
2021Chapter 4 introduced important methods to enhance the resolution limits of lithography by modifying components of the optical imaging system, especially the mask and the illumination. These optical resolution enhancements aim to improve the image or intensity distribution that exposes the photoresist.

Alkali ash material, a novel material for infrastructure enhancement
Engineering Structures, 2001Many studies have focused on the conversion of fly ash from coal burning operations to a useful material. However, out of 55 million tons of fly ash generated in the United States, only 27% is being reused or recycled. Alkali Ash Material (AAM) is a novel material, which is made by converting fly ash to a useful construction material, with several ...

Absorption by an Actively Enhanced Material
Active Control of Vibration and Noise, 1994Abstract Active control is used here to improve the natural acoustic performances of an absorbent material. The method consists of backing an absorbent material panel with an actuator so as to control the panel backward impedance, and hence to optimize the material properties.

Technologically enhanced naturally occurring radioactive materials
Clinical Toxicology, 2009Naturally occurring radioactive materials (NORM) are ubiquitous throughout the earth's crust. Human manipulation of NORM for economic ends, such as mining, ore processing, fossil fuel extraction, and commercial aviation, may lead to what is known as "technologically enhanced naturally occurring radioactive materials," often called TENORM. The existence

RFID enhances materials handling
Sensor Review, 1995Describes developments in radio frequency identification [RFID] techniques, using examples from existing applications in the motor industry, breweries and mail order companies. Looks at the miniaturization resulting from integrated circuit technology, the advantages of passive transponders and one of the latest versions of transponder, the Multipage [M/

GRADIENT ENHANCED DAMAGE FOR QUASI-BRITTLE MATERIALS
International Journal for Numerical Methods in Engineering, 1996Summary: Conventional continuum damage descriptions of material degeneration suffer from loss of well-posedness beyond a certain level of accumulated damage. As a consequence, numerical solutions are obtained which are unacceptable from a physical point of view.

Materialized View Tuning Mechanism and Usability Enhancement
2006The materialized view technology has been widely adopted in the data warehouse systems to improve query performance. Two key underlying techniques are materialized view incremental refresh and query rewrite. However, due to the potential complexity of the materialized view defining query and dependency on the materialized view change log, not all ...
