Research Hotspot Prediction and Regular Evolutionary Pattern Identification Based on NSFC Grants Using NMF and Semantic Retrieval [PDF]
IEEE Access, 2019 Analyzing the research hotspots and regular evolutionary patterns of R&D projects can help researchers find potential information. This paper considers the titles of the National Natural Science Foundation of China (NSFC) grants that have been awarded in the past 20 years as the research objects.

Algebrodynamics: Shear-Free Null Congruences and New Types of Electromagnetic Fields [PDF]
Axioms, 2023, 12, 1061, 2023 We briefly present our version of noncommutative analysis over matrix algebras, the algebra of biquaternions ($\mathbb B$) in particular. We demonstrate that any $\mathbb B$-differentiable function gives rise to a null shear-free congruence (NSFC) on the $\mathbb B$-vector space $\mathbb{C}\bf M$ and on its Minkowski subspace $\bf M$. Making use of the

Extensions of some matrix inequalities related to trace and partial traces [PDF]
Linear Algebra and its Applications 639 (2022) 205-224, 2020 We first present a determinant inequality related to partial traces for positive semidefinite block matrices. Our result extends a result of Lin [Czech. Math. J. 66 (2016)] and improves a result of Kuai [Linear Multilinear Algebra 66 (2018)]. Moreover, we provide a unified treatment of a result of Ando [ILAS Conference (2014)] and a recent result of Li,

IFAC-PapersOnLine, 2016 Abstract: This paper investigates a remote state estimation problem over a communication channel, which is of theoretical and practical significance in the study of cyber-physical systems (CPS). In consideration of both bandwidth limitation and estimation quality, an event-based schedule is proposed to decide whether to transmit the current ...

Magneto-Rayleigh-Taylor instability driven by a rotating magnetic field: Cylindrical liner configuration [PDF]
IEEE Trans. Plasma Sci., 2019, 2017 We propose using a directional time-varying (rotating) driving magnetic field to suppress magneto-Rayleigh-Taylor (MRT) instability in dynamic Z-pinches. A rotational drive magnetic field is equivalent to two magnetic-field components, {\Theta} and Z, that alternate in time, referred to as an alternate Theta-Z-pinch configuration.

IFAC-PapersOnLine, 2016 Abstract: This paper proposes a Morkov state transition model for an isolated intersection in urban traffic and formulates the traffic signal control problem as a Markov Decision Process(MDP). In order to reduce computational burden, a sensitivity-based policy iteration(PI) algorithm is introduced to solve the MDP. The proposed model is stage-varying

IFAC-PapersOnLine, 2015 Abstract As RNA-seq becomes the main application for gene expression profiling, many computational methods have been developed for analysis of differential expression (DE) genes in RNA-seq data. However, most existing algorithms prefer to call long genes as DE.

IFAC-PapersOnLine, 2016 Abstract This paper presents the real-time moving horizon estimation (MHE) for Moving Long Baseline (MLBL) positioning system. By establishing the linear positioning model, we formulate MLBL positioning problem in a linear, time-invariant, discrete-time system.

IFAC-PapersOnLine, 2015 Abstract Chemical processes usually work under different operating modes to meet the market demand and to achieve higher profits. This necessitates investigating related algorithms and alarm systems for multimodal chemical processes. Although some research effort has been made to monitor multimodal processes, little attention was paid to fault ...

IFAC-PapersOnLine, 2016 Abstract Since urban traffic congestion has been a serious problem for several decades, a traffic signal control algorithm based on the model focusing on the dynamic behavior of links is developed in this paper. In the optimization process, the difference between the input capacity and output capacity of a link is optimized to make full advantages of
