Structure of turbulent velocity field in the discharge stream from a standard Rushton turbine impeller [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2017
The radial discharge jet from a standard Rushton turbine was investigated by the Laser Doppler Anemometry (LDA) method. Several distances from the impeller blades (in the radial direction) were chosen for the measurement of axial profiles: all three ...

Radial velocity data analysis with compressed sensing techniques [PDF]

open access: yes, 2016
We present a novel approach for analysing radial velocity data that combines two features: all the planets are searched at once and the algorithm is fast.

Static and Dynamic Behavior of Novel Y‐Shaped Sandwich Beams Subjected to Compressive Loadings: Integration of Supervised Learning and Experimentation

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, the mechanical response of Y‐shaped core sandwich beams under compressive loading is investigated, using deep feed‐forward neural networks (DFNNs) for predictive modeling. The DFNN model accurately captures stress–strain behavior, influenced by design parameters and loading rates.

Precise Radial Velocities [PDF]

open access: yesInternational Astronomical Union Colloquium, 1992
AbstractCurrent techniques for the detection of long-term, low-amplitude (<50 m s−1), radial velocity variations are briefly reviewed together with some of their most successful programs. In the era of 8- to 10-m telescopes we must strive for a precision of < 1ms−1.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Optimisasi Waktu Tempuh Pada Multi-AGV Menggunakan Particle Swarm Optimization

open access: yesJurnal Ilmiah Teknik Industri, 2016
An algorithm for velocity planning on a continuous-curvature path of a pair of automated guided vehicles (AGVs) that minimizing its travelling time is presented. A class of 3-degree Bezier curves is used as basic form of the path.

Search for DA White Dwarf Binary Candidates from LAMOST DR7

open access: yesUniverse, 2023
We obtained spectroscopy data for 761 Degenerate A (DA)white dwarfs (WDs) with multiple LAMOST observations. The radial velocity (RV) of each spectrum was calculated using the cross-correlation function method (CCF), and 60 DA WD binary candidates were ...
