Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

A Subthreshold Symmetric SRAM Cell With High Read Stability

IEEE Transactions on Circuits and Systems II: Express Briefs, 2014
This brief introduces a differential eight-transistor static random access memory (SRAM) cell for subthreshold SRAM applications. The symmetric topology offers a smaller area overhead compared with other symmetric cells for the same stability in the read operation.

STT-RAM read stability in DRAM operating region

2015 15th Non-Volatile Memory Technology Symposium (NVMTS), 2015
Spin-transfer-torque RAM (STT-RAM) is the most promising candidate for replacing DRAM while gaining an additional function of non-volatility. The relationship between rapid increase of spin-inversion current and stability of read operation (read disturbance) in the DRAM-array operating time region of less than 10 ns (i.e., "fast" region) was examined ...

SRAM cell with better read and write stability with Minimum area

TENCON 2019 - 2019 IEEE Region 10 Conference (TENCON), 2019
This paper describes a novel SRAM architecture to improve read and write stability. Read stability is enhanced by increasing $\beta$ ratio to 4 and write stability is enhanced by storage node charging and discharging through two transistors. The proposed 8T SRAM architecture is compared with Conventional 6T, decoupled 8T SRAM cell and 10T SRAM cell ...

Word reading and reading comprehension: stability, overlap and independence

Reading and Writing, 2007
Longitudinal twin data were analyzed to investigate the etiology of the stability of genetic and environmental influences on word reading and reading comprehension, as well as the stability of those influences on their relationship. Participating twin pairs were initially tested at a mean age of 10.3 years, and retested approximately five years later ...

Etiology of the Stability of Reading Difficulties: The Longitudinal Twin Study of Reading Disabilities

Twin Research and Human Genetics, 2007
AbstractResults obtained from previous longitudinal studies of reading difficulties indicate that reading deficits are generally stable. However, little is known about the etiology of this stability. Thus, the primary objective of this first longitudinal twin study of reading difficulties is to provide an initial assessment of genetic and environmental

Prediction and Stability of Reading Problems in Middle Childhood

Journal of Learning Disabilities, 2013
The longitudinal prediction of reading problems from fourth grade to sixth grade was investigated with a sample of 173 students. Reading problems at the end of sixth grade were defined by significantly below average performance (≤ 15th percentile) on reading factors defining word reading, fluency, and reading comprehension.

Boosted sensing for enhanced read stability in STT-MRAMs

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
Read access in STT-MRAMs is well known to be highly sensitive to process variations. Such variations are responsible for read bit error rates that are worse than conventional CMOS memories (e.g., SRAM) by orders of magnitude, especially at low voltages.

Ocular Dominance Stability and Reading Skill: A Controversial Relationship

Optometry and Vision Science, 2011
ABSTRACT Purpose. Evidence is mixed concerning the relationship between stability of ocular dominance and reading deficits. Contrasting results may be due to the use of different tests of dominance, different samples of readers, and different scoring methods.
