Intermetallic phases and element distribution in carbon-free PM high-speed steels of the Fe-Co-Mo type

European Journal of Materials
In contrast to classical carbidic high-speed steels, carbon-free grades of the type Fe-Co-Mo(-W) obtain their strength by precipitation hardening through nm-size intermetallic µ phases; for example, (Fe,Co)7Mo6; coa­rser µ phases, in the low µm range ...

Effect of the change of firing temperature on microstructure and physical properties of clay bricks from Beruas (Malaysia) [PDF]

Science of Sintering, 2010
This study is focused on the behaviour of fired-clay brick from the area around Beruas (Malaysia) that is known for it brick industries. The firing temperatures were set from 800°C to 1250°C and soaking time was fixed for an hour.

Phase synchronization analysis by assessment of the phase difference gradient

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2009
Phase synchronization is an important phenomenon of nonlinear dynamics and has recently received much scientific attention. In this work a method for identifying phase synchronization epochs is described which focuses on estimating the gradient of segments of the generalized phase differences between phase slips in an experimental time series. In phase

Dense-Frequency Signal-Detection Based on the Primal–Dual Splitting Method

Entropy, 2022
Aiming to solve the problem of dense-frequency signals in the power system caused by the growing proportion of new energy, this paper proposes a dense-frequency signal-detection method based on the primal–dual splitting method.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Sequence Phase Analysis of Phased Rectifier

TELKOMNIKA Indonesian Journal of Electrical Engineering, 2013
At present, three-phase bridge type full controlled is the most widely applied in all kinds of rectifier circuit. To guarantee the normal work of the phase control circuit, it is the most important thing that should be according to the size of the triggering angle at the right moment to the thyristor trigger of the circuit on effective puls.

Phase Analysis of Quantum Oscillations in Graphite [PDF]

Physical Review Letters, 2004
The quantum de Haas van Alphen (dHvA) and Shubnikov de Haas (SdH) oscillations measured in graphite were decomposed by pass-band filtering onto contributions from three different groups of carriers. We develop the two-dimensional phase analysis method which allows to identify these carriers as (i) minority holes having two-dimensional (2D) parabolic ...
