Information Uncertainty and the Momentum Effect [PDF]

, 2008
I identify simple proxies for uncertainty and attempt to determine if the returns to a momentum strategy vary with these proxies. The proxies identified include the stock’s daily 6-month historical return volatility, the magnitude of alpha in a 6-month ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Firm characteristics that drive the momentum pattern in the UK stock market [PDF]

, 2013
Previous studies have estimated the company characteristics of previous winners and losers to explore the momentum effect. Using UK data, this study focuses on the characteristics of companies that actually generate the momentum pattern.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Note on post-Minkowskian expansion and Bondi coordinates

Nuclear Physics B
In this note, we transform the linear order (at order G) metric from a system of pointlike bodies source in the post-Minkowskian expansion to the Bondi coordinates.

Controllable Rotations of Spiraling Elliptic Beams in Anisotropic Linear Media

IEEE Photonics Journal, 2017
We study the rotation properties of spiraling elliptic beams in the anisotropy media. Based on the Collins formula, we obtain the exact analytical solution of the spiraling elliptic beams carrying the orbital angular momentum (OAM) to the paraxial wave ...

Is Momentum Really Momentum? : International Evidence [PDF]

, 2011
Novy-Marx (2010) finds that momentum is primarily driven by stock performance twelve to seven months prior to portfolio formation in the US market. We examine whether this finding holds in international stock markets.

Mass-Energy-Momentum: Only there because of Spacetime? [PDF]

, 2010
I describe how relativistic field theory generalises the paradigm property of material systems, the possession of mass, to the requirement that they have a mass-energy-momentum density tensor associated with them.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Colisão com o 'efeito estilingue'

Revista Brasileira de Ensino de Física
Abordamos teoricamente a colisão com o 'efeito estilingue' onde um corpo transfere momento linear e energia cinética para um segundo corpo de massa menor, fazendo com que a energia mecânica desse segundo corpo cresça de forma surpreendente. Mostramos que,
