External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

open access: yesAdvanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

open access: yesAdvanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Implicit Rating and Filtering [PDF]

open access: yes, 1998
Social filtering systems that use explicit ratings require a large number of ratings to remain viable. The effort involved for a user to rate a document may outweigh any benefit received, leading to a shortage of ratings.

Distributed State Estimation for Multi-Agent Systems With Random Transmission Delays

open access: yesIEEE Access
This paper investigates the distributed state estimation problem of a class of multi-agent systems with random transmission delay. The random transmission delay phenomenon is described by a random variable that obeys a Bernoulli distribution.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Optimal HP filtering for South Africa [PDF]

open access: yes
Among the various methods used to identify the business cycle from aggregate data, the Hodrick-Prescott filter has become an industry standard – it ‘identifies’ the business cycle by removing low-frequency information, thereby smoothing the data.

Filtering for jump-diffusion models by statistical modeling method

open access: yesНаучный вестник МГТУ ГА, 2016
This article develops new methods that reduce the optimal filtering problem for jump-diffusion models to the analysis problem for the special stochastic system with jumps, branching and terminating trajectories. Earlier appropriate methods and algorithms

Filtering Algorithm on Arbitrary-Step-Lag Out-of-Sequence Measurement Based on Selective Fusion [PDF]

open access: yesJisuanji gongcheng, 2018
In target tracking system,because the sensor has different preprocessing time and sampling rate,and the inherent random communication delay of the channel,the phenomenon of random arrival of the fusion center may appear in the sensor data,that is,the ...

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

open access: yesAdvanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

On Filtering in Markovian Term Structure Models (An Approximation Approach) [PDF]

open access: yes
We study a nonlinear filtering problem to estimate, on the basis of noisy observations of forward rates, the market price of interest rate risk as well as the parameters in a particular term structure model within the Heath-Jarrow-Morton family.
