In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Advanced Engineering Materials, EarlyView.Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Velocity-to-velocity human motion forecasting
Pattern Recognition, 2022Abstract Forecasting human motion from a sequence of human poses is an important problem in the fields of computer vision and robotics. Most previous approaches merely consider learning the temporal dynamics of body joints or joint angles, while neglect derivatives of body joints (i.e., pose velocities) which could reasonably reduce noise impact and ...

Pediatrics, 1973
The concept of velocity, or incremental, growth is difficult for some to grasp, perhaps because of a deeply embedded misconception that a baby starts to grow and does so steadily through the seven ages of man. But the rate or speed of growth is clearly not constant, nor are its inconstancies themselves constant in all individuals.

How can the health (or the robustness) of a complex information processing system be quantitatively scored? This question applies to both subjective and quantified assessments of health. Given that subjective assessments are routine, how can such assessments be quantified? This paper presents an approach, based on an analogy drawn between economies and

PDFs for velocity and velocity gradients in Burgers’ turbulence
Physics of Fluids, 1995We characterize the tails of the probability distribution functions for the solution of Burgers’ equation with Gaussian initial data and its derivatives ∂kv(x,t)/∂xk, k=0,1,2,... . The tails are ‘‘stretched exponentials’’ of the form P(θ)∝exp[−(Re)−ptqθr], where Re is the Reynolds number. The exponents p, q, and r depend on the initial spectrum as well

Science, 1927
In an article entitled as above and published on page 381 of SCIENCE for October 21, 1927, an error was made in the value of a constant in the last line of the article. This line should read V = 331.4 (1- 4.45 × 10 -3 /d n .53 ) meters/sec

The velocity of circulation of money is V in the identity of exchange $$ MV \equiv PT $$ which is due to Irving Fisher (1911). On the left-hand side, M is the stock of money capable of ready payment, i.e. currency and demand deposits, or, in modern parlance, M1; on the right, P is the price level and T stands for the volume of trade.

Velocity anticipation in the optimal velocity model
Journal of Shanghai University (English Edition), 2009In this paper, the velocity anticipation in the optimal velocity model (OVM) is investigated. The driver adjusts the velocity of his vehicle by the desired headway, which depends on both instantaneous headway and relative velocity. The effect of relative velocity is measured by a sensitivity function.
