This study aims to investigate the role of industrial Internet platform in facilitating digital transformation traditional manufacturing enterprises. While prior research has predominantly focused on enterprises, there is a noticeable dearth concerning enterprises lacking resources establish such platforms. To address this gap, we conduct an exploratory case and propose affordances upgrade model that elucidates business process these leveraging The findings can be summarized from two key...
Fractional order proportional-integral-derivative(FOPID) controllers have attracted increasing attentions recently due to their better control performance than the traditional integer-order proportional-integral-derivative (PID) controllers. However, there are only few studies concerning fractional of microgrids based on evolutionary algorithms. From perspective multi-objective optimization, this paper presents an effective FOPID frequency controller design method called MOEO-FOPID for...
As the penetration level of renewable distributed generations such as wind turbine generator and photovoltaic stations increases, load frequency control issue a multi-area interconnected power system becomes more challenging. This paper presents an adaptive model predictive method for with generation by considering some nonlinear features dead band governor rate constraint steam turbine. The dynamic characteristic this is formulated discrete-time state space firstly. Then, obtained...
ABSTRACT This article investigates the asymptotic stability of discrete‐time switching systems in which modulus all subsystem eigenvalues are greater than one. The study begins by constructing an energy function with practical physical meaning for each subsystem. Specifically, a standard linear discrete system is derived discretizing single‐degree‐of‐freedom vibratory model, its defined as sum model's kinetic and potential energies. An invertible transform then applied to convert general...
Based on the facts that there is no obvious improvement in injection conformance and significant water cut reduction production wells after polymer flooding S oilfield Bohai Bay, this study used cross-linked microspheres-polymer composite to research effect of chemical system composition, displacement speed, volume by physical simulation experiments, optimize parameters system. The results showed higher concentration microspheres at a total 1750 mg/L, more oil recovery enhancement; 1350−...
The rapid digital transformation and the imperative for sustainable practices have made it crucial Chinese manufacturing enterprises to adapt achieve green product innovation by effectively utilizing technologies. This study takes a resource-based perspective from strategic management develops chain mediation model examine how can through empowerment. A questionnaire survey was conducted with 229 managers, multiple employed test hypotheses. findings highlight that higher level of business...
In this paper, the inverse method of nonlinear systems with a nonlinearity is presented, and adaptive control algorithm type established. This also suitable for unstable (or) systems, achieves virtually asymptotically optimal may ensure closed-loop to be globally convergent stable by choosing weighted polynomials. The simulation results show that can overcome affection improve performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Human motion recognition based on inertial sensor is a new research direction in the field of pattern recognition. It carries out preprocessing, feature selection, and selection by placing sensors surface human body. Finally, it mainly classifies recognizes extracted features action. There are many kinds swing movements table tennis. Accurately identifying these movement modes great significance for analysis. With development artificial intelligence technology, has made breakthroughs recent...
To forecast some key parameters of produced liquid containing polymer, including the time polymer output, concentration, a concentration prediction method based on interwell connectivity methodology was established, its results were compared with those from numerical simulation software, and it has been used in case study. On basis water flooding model, production performance model considering viscosity, adsorption water-phase permeability reduction factor built. Compared traditional...
Abstract Objective The objective of this study was to develop a parenting assessment tool (PAT) for parents children aged 3 6 years assess attitudes and skills within the Chinese socio‐cultural context. Methods participants Focus group discussions were used gather information composing PAT test items. Factor analysis performed build refine factor structure PAT. Ten cities included in larger programme, Early Childhood Development Promotion Project carried out by Capital Institute Pediatrics...
Aiming at optimizing polymer flooding, we establish an optimal control model of which has objective function the net present value (NPV) involving effect injection. An improved Monte Carlo gradient approximation (MCGA) algorithm, based on idea ensemble-based optimization (EnOpt) scheme to solve problem strongly fluctuating perturbation gradients, is proposed by introducing covariance matrix vectors filter and smooth searching direction. A synthetic heterogeneous reservoir built test...
This study presents a novel fractional order grey model FGM ([Formula: see text],1) obtained by extending the (GM (1,1)). For this, we generalize whitenization first-order differential equation to using Caputo derivative of [Formula: text]. A real-world case study, scrutinize economic growth influence on environmental degradation in Turkey, is performed evaluate significance projected contrast current classical GM. We apply autoregressive distributed lags bounds testing co-integration...

Purpose We aimed to investigate risk factors for COVID-19 pneumonia in patients with hematological malignancies (HM) after Omicron infection. Methods Data from a registered multi-center, prospective, observational study (ChiCTR2300071830) during the latest BA.5.2 wave Chongqing, China was used analysis. Results A total of 475 HM enrolled this study. observed 15.8% (75/475) patients, median age 58 years (interquartile range [IQR], 48-69 years) and males accounting 61.3%. Risk associated...
Acute myeloid leukemia (AML) is characterized by abundant immature cells, relapse and refractory due to stem cells (LSCs). Bone marrow mesenchymal stem/ stromal (BMSCs) supported LSCs survival, meanwhile, chemotherapy improved connexin43 (CX43) expression. CX43, as the most intercellular gap junction, facilitated transmit mitochondria from BMSCs into AML. We hypothesized that increased transferred metabolic remodeling in sustain their stemness. Primary AML patients were isolated. CX43-BMSCs,...
