The Influence Mechanism of Deformation on the Precipitation Behavior and Mechanical Properties of 7075 Aluminum Alloy During Hot Forming-Quenching Integrated Process

open access: yesMetals
The hot forming-quenching integrated process (HFQ®) organically combines the deformation and heat treatment, which can improve the forming performance of aluminum alloy while ensuring the final strength of formed parts.

Safe Neighborhood Computation for Hybrid System Verification

open access: yes, 2015
For the design and implementation of engineering systems, performing model-based analysis can disclose potential safety issues at an early stage. The analysis of hybrid system models is in general difficult due to the intrinsic complexity of hybrid ...

The discrete dynamics of small-scale spatial events: agent-based models of mobility in carnivals and street parades [PDF]

open access: yes, 2002
Small-scale spatial events are situations in which elements or objects vary in such away that temporal dynamics is intrinsic to their representation and explanation. Someof the clearest examples involve local movement from conventional traffic modelingto

Consumer attitudes and preference exploration towards fresh-cut salads using best–worst scaling and latent class analysis [PDF]

open access: yes, 2019
This research explored the preferences and buying habits of a sample of 620 consumers of fresh-cut, ready-to-eat salads. A best–worst scaling approach was used to measure the level of preference stated by individuals regarding 12 attributes for quality ...

Design of mine-used intrinsically safe line array X-ray receiving box

open access: yesGong-kuang zidonghua, 2021
The mine-used explosion-proof line array X-ray receiving box is not suitable for nondestructive testing of high-speed conveyor belts. And there are difficulties in processing the explosion-proof enclosure and heavy weight for nondestructive detection of ...

Bolt Detection Signal Analysis Method Based on ICEEMD

open access: yes, 2018
The construction quality of the bolt is directly related to the safety of the project, and as such, it must be tested. In this paper, the improved complete ensemble empirical mode decomposition (ICEEMD) method is introduced to the bolt detection signal ...

The renormalization of fluctuating branes, the Galileon and asymptotic safety

open access: yes, 2013
We consider the renormalization of d-dimensional hypersurfaces (branes) embedded in flat (d+1)-dimensional space. We parametrize the truncated effective action in terms of geometric invariants built from the extrinsic and intrinsic curvatures.

Applications of Phyllosilicates Mineral Powder as Anti-Wear Lubricating Materials in Lubricating Oil and Grease: A Review

open access: yesLubricants
Wear caused by friction is one of the main causes of most mechanical component failures. The application of powders as anti-wear lubricating materials has achieved great advances, which are of great significance in reducing friction and wear. This review
