THE INFLUENCE MECHANISMS OF ILLEGITIMATE TASKS ON EMPLOYEES’ SILENCE BEHAVIORS AGAINST THE BACKDROP OF ARTIFICIAL INTELLIGENCE AND FUZZY ALGORITHMS

Employee silence can degrade the working environment and decrease employees’ motivation and commitment to an organization. As a result, it not only affects employees but also reduces the productivity of the organization. However, few studies have investigated the influencing mechanisms of employee silence empirically. This paper studies how illegitimate tasks affect employee silence based on artificial intelligence and fuzzy algorithms. We surveyed 325 employees in several medium-sized enterprises in Jiangsu and Anhui, China. According to the findings, emotional exhaustion partially mediates the relationship between illegitimate tasks and employees’ silence behaviors, and leadership humor can moderate the positive effect of illegitimate tasks on emotional exhaustion. Therefore, situating the mechanisms underlying employees’ silence behaviors in the context of artificial intelligence and fuzzy algorithm research helps researchers understand the relationship between illegitimate tasks and employees’ silence behaviors, thus improving related research on silence behaviors

Bestimmung der im Seegang zusätzlich erforderlichen Antriebsleistung von Schiffen

Bestimmung der im Seegang zusätzlich erforderlichen Antriebsleistung von Schiffen Die Ergebnisse dieser Arbeit zeigen am Beispiel eines Containerschiffs, daß eine recht genaue Bestimmung des Zusatzwiderstandes und des Mehrleistungsbedarfs eines Schiffes in regelmäßigen Wellen und im unregelmäßigen Seegang mit dem Programmsystem ZWBF6G durchgeführt werden kann. Es zeigte sich, daß bei mittleren Seegangszuständen und mäßigen Geschwindigkeiten die Widerstandserhöhung bereits in der Größenordnung des Glattwasserwiderstandes liegt. Unter Zugrundlegung eines Seegebietes mit bekannter Langzeitverteilung von Seegangs- und Winddaten sowie Kursverteilungen für das Schiff lassen sich dann Mittelwerte für die erreichbare Geschwindigkeit und den Leistungsbedarf über lange Zeiträume angeben

Beschreibung des Programmsystems BUEF6G

Beschreibung des Programmsystems BUEF6G 1955 wurde erstmalig von Korvin-Kroukovsky eine Methode zur Berechnung der gekoppelten Tauch- und Stampfschwingungen eines Schiffes in längslaufenden regelmäßigen Wellen vorgestellt. In den darauffolgenden Jahren wurde diese Streifentheorie schnell entwickelt und durchgängig hydrodynamisch auf eine potentialtheoretische Grundlage gestellt. Zur Zeit wird die Streifenmethode als zweckmäßigstes Verfahren zur Berechnung der Bewegung und Belastung von Schiffen im Seegang angesehen. Die bisherigen Streifenmethoden sind ausnahmslos durch die Voraussetzung des Schiffes als schlanker Körper sowie die Annahme kleiner Schwingungsamplituden charakterisiert. Mittlerweile existieren mehr als 20 verschiedene Versionen, die sich auf Grund des Näherungscharakters der Streifentheorie in der unterschiedlichen Erfassung des Geschwindigkeits-einflusses einschließlich der Erfüllung gewisser Symmetriebedingungen für die Dämpfungskopplungskoeffizienten, aber auch in der Bestimmung der Form der Spantquerschnitte, der Erfassung der Diffraktionswirkungen und der Einführung verbesserter Ansätze bei der Rolldämpfung unterscheiden. Das im folgenden beschriebene Programmsystern ist eine Fortentwicklung des vorgestellten Verfahrens zur Bestimmung der Übertragungsfunktionen der Bewegungen eines schlanken, symmetrischen Schiffes mit beliebigem Beladungs-zustand in regelmäßigen Wellen aus beliebigen Richtungen

A Patent Bibliometric Analysis of Carbon Capture, Utilization, and Storage (CCUS) Technology

Large amounts of CO2 from human socioeconomic activities threaten environmental sustainability. Moreover, uncontrolled resource use and lack of relevant technology exacerbate this issue. For this reason, carbon capture, utilization, and storage (CCUS) technology has gained worldwide attention. Many scholars have researched CCUS, but few have used CCUS patent bibliometric analysis from a unified perspective. This article aims to provide a conclusive analysis for CCUS researchers and policymakers, as well as summarize the innovation trends, technological distribution, and topic evolution. Based on 11,915 pieces of patent data from the Derwent Innovations Index, we used bibliometric analysis and data mining methods to conduct research on four dimensions: overall trend, geographical distribution, patentees, and patent content. The results of this article are as follows. CCUS has entered a rapid development stage since 2013. Patents are mainly distributed geographically in China, the US, and Japan, especially in heavy industries such as energy and electricity. Large enterprises hold patents with a relatively stable network of cooperators and attach great importance to international patent protection. A total of 12 topics were identified through clustering, and these topics gradually shifted from technicalities to commercialization, and from industrial production to all aspects of people’s daily lives

Tropospheric Second-Order Horizontal Gradient Modeling for GNSS PPP

The asymmetric delay has a considerable impact on Global Navigation Satellite Systems (GNSS) Positioning, Navigation and Timing (PNT) applications. In GNSS analyses, the impacts of the asymmetric delay are commonly compensated by using the classical methods with considering the north-south and east-west horizontal gradients. In this paper, we have initiatively proposed an extended method where the north-south and east-west horizontal gradients as well as the second-order horizontal gradients are included to better fit the asymmetric delay. The modeling accuracy of the extended method was evaluated at globally distributed 905 GNSS stations during 40 days in 2020. Significant performance of the extended method respect to the classical method was found, where the hydrostatic and wet modeling accuracy at 4° elevation angle was improved from 5.3 and 10.6 mm to 1.6 and 4.9 mm by 70% and 54%, respectively. The GNSS Precise Point Positioning (PPP) performance using the extended method was also validated at 107 Multi-GNSS Experiment (MGEX) stations. The superior performance on the coordinate repeatability and significant effectiveness on the coordinate and Zenith Total Delay (ZTD) estimations were also found, and the maximal vertical (U) coordinate and ZTD difference biases reached 8.6 and −4.5 mm. The extended method is therefore recommended to substitute the classical methods in the GNSS analyses, especially under severe atmospheric conditions

WTM: The Site-Wise Empirical Wuhan University Tropospheric Model

The tropospheric model is the key model in space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI). In this paper, we established the site-wise empirical Wuhan University Tropospheric Model (WTM) by using 10-year (2011–2020) monthly mean and 5-year (2016–2020) hourly ERA5 reanalysis data, where the Zenith Path Delay (ZPD), mapping function, and horizontal gradient as well as meteorological parameters are provided at 1583 specific space geodetic stations with additionally considering the diurnal and semi-diurnal variations. The mapping function and horizontal gradient from the WTM model were evaluated at 524 globally distributed GNSS stations during the year 2020 and compared with the latest grid-wise (1° × 1°) Global Pressure and Temperature 3 (GPT3) model. The significant improvements of the WTM model to the GPT3 model were found at the stations with terrain relief, and the maximal mapping function and horizontal gradient accuracy improvements reached 12.8 and 14.71 mm. The ZPD and mapping functions from the two models were also validated at 31 Multi-GNSS Experiment (MGEX) stations spanning the year 2020 by BeiDou Navigation Satellite System (BDS) Precise Point Positioning (PPP). The significant vertical coordinate and ZTD difference biases between the PPP schemes adopted by the two models were also found, and the largest biases reached −1.78 and 0.87 mm

Supercritical Fluid Microcellular Foaming of High-Hardness TPU via a Pressure-Quenching Process: Restricted Foam Expansion Controlled by Matrix Modulus and Thermal Degradation

High-hardness thermoplastic polyurethane (HD-TPU) presents a high matrix modulus, low-temperature durability, and remarkable abrasion resistance, and has been used in many advanced applications. However, the fabrication of microcellular HD-TPU foam is rarely reported in the literature. In this study, the foaming behavior of HD-TPU with a hardness of 75D was investigated via a pressure-quenching foaming process using CO2 as a blowing agent. Microcellular HD-TPU foam with a maximum expansion ratio of 3.9-fold, a cell size of 25.9 μm, and cell density of 7.8 × 108 cells/cm3 was prepared, where a high optimum foaming temperature of about 170 °C had to be applied with the aim of softening the polymer’s matrix modulus. However, the foaming behavior of HD-TPU deteriorated when the foaming temperature further increased to 180 °C, characterized by the presence of coalesced cells, microcracks, and a high foam density of 1.0 g/cm3 even though the crystal domains still existed within the matrix. The cell morphology evolution of HD-TPU foam was investigated by adjusting the saturation time, and an obvious degradation occurred during the high-temperature saturation process. A cell growth mechanism of HD-TPU foams in degradation environments was proposed to explain this phenomenon based on the gas escape through the defective matrix

Results show that there is different broadening of Au M X-ray owing to multiply ionized effect in the collision with heavy ions, the degree of ionization mainly depends on the distribution of the electronic states in the ions&#39; outer shell. The yield of X-ray is calculated and compared with BEA (binary encounter approximation) model, and the effect of ion charge state on the X-ray yield is also discussed.</span
