Large‐Scale and Highly Reliable Hopfield Neural Networks Using Vertical NAND Flash Memory for the In‐Memory Associative Computing

Advanced Intelligent Systems, EarlyView.
Large‐scale Hopfield neural networks (HNNs) for associative computing are implemented using vertical NAND (VNAND) flash memory. The proposed VNAND HNN with the asynchronous update scenario achieve robust image restoration performance despite fabrication variations, while significantly reducing chip area (≈117× smaller than resistive random‐access ...

Integer Ambiguity Resolution Algorithm Based On Different Baseline Method

DEStech Transactions on Computer Science and Engineering, 2018
Carrier phase observation can greatly improve the accuracy of navigation and positioning, but the existence of ambiguity will seriously affect the accuracy of the results. This paper analyzes the advantages and disadvantages of LAMBDA algorithm for integer ambiguity resolution. The problem of constructing search domain leads to long search time.

ON THE REALISTIC STOCHASTIC MODEL OF GPS OBSERVABLES: IMPLEMENTATION AND PERFORMANCE [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
High-precision GPS positioning requires a realistic stochastic model of observables. A realistic GPS stochastic model of observables should take into account different variances for different observation types, correlations among different observables ...

A Review of GNSS Carrier Phase Ambiguity Resolution and Conceptual AI-Driven Approaches

Engineering Proceedings, 2023
Precise Point Positioning (PPP) with Integer Ambiguity Resolution (IAR) is an effective way of improving the overall performance of the PPP technique both in terms of convergence time and accuracy. Even though PPP-IAR has seen a tremendous development in

Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

Annals of Neurology, EarlyView.
Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

Detailed Investigation on Ambiguity Validation of Long-Distance RTK

Remote Sensing
Long-distance Real-Time Kinematic (RTK) positioning is crucial for applications in remote areas, such as maritime environments. Achieving 2–3 cm accuracy with RTK requires successful ambiguity resolution, which involves two main steps: identifying the ...

Improving integer ambiguity resolution for GLONASS precise orbit determination

Journal of Geodesy, 2016
The frequency division multiple access adopted in present GLONASS introduces inter-frequency bias (IFB) at the receiver-end both in code and phase observables, which makes GLONASS ambiguity resolution rather difficult or even not available, especially for long baselines up to several thousand kilometers.
