The research progress of empirical mode decomposition and mode mixing elimination
Dianzi Jishu Yingyong, 2019 The Empirical Mode Decomposition(EMD) algorithm proposed by Huang is a data driven adaptive analysis method for nonlinear time-varying signals. The signals can be decomposed into a few Intrinsic Mode Functions(IMFs) components with physical meaning ...

[Multilingualism and Mixed-Mode Communication
, 2023 Like other disciplines, the field of sociolinguistics is not a homogenous one. It rather comes in three “loosely connected waves” (Eckert 2012) with each wave applying specific sets of methods. How can we use methodological triangulation and combine these methods, both quantitative and qualitative in nature, to integrate the three waves of ...

Mixed-Mode Pandemic Modeling [PDF]
2019 Winter Simulation Conference (WSC), 2019 This paper describes a mixed mode approach to simulating a global pandemic. It describes the architectural and design decisions as well as the data sources, development tools and processes in each of the three simulation domains - System Dynamics (SD), Discrete Event Simulation (DES) and Agent-Based Modeling (ABM). The encompassing model uses a network

A Mixing Process Influenced by Wall Jet-Induced Shock Waves in Supersonic Flow
Applied Sciences, 2022 With the development of hypersonic air-breathing propulsion systems, such as the supersonic combustion ramjet (Scramjet) and rocket-based combined cycle (RBCC) engines, the mixing process of supersonic airstream with fuel in the engine combustor has been

Effects of mixing modes on nonresponse and measurement error in an economic panel survey
Journal for Labour Market Research, 2023 Numerous panel surveys around the world use multiple modes of data collection to recruit and interview respondents. Previous studies have shown that mixed-mode data collection can improve response rates, reduce nonresponse bias, and reduce survey costs ...

Tracking text in mixed-mode documents [PDF]
Proceedings of the ACM conference on Document processing systems - DOCPROCS '88, 1988 This paper describes a method for extracting arbitrarily oriented text in documents containing both text and graphics. The technique presented is inspired by the tracking algorithms frequently found in raster to vector conversion systems. By identifying text components in the document, reducing the resolution of the image by the size of the characters,
