Generative AI (GAI) has emerged as a significant advancement in artificial intelligence, renowned for its language and image generation capabilities. This paper presents "AIGenerated Everything" (AIGX), a concept that extends GAI beyond mere content creation to real-time adaptation and control across diverse technological domains. In networking, AIGX collaborates closely with physical, data link, network, and application layers to enhance real-time network management that responds to various system and service settings as well as application and user requirements. Networks, in return, serve as crucial components in further AIGX capability optimization through the AIGX lifecycle, i.e., data collection, distributed pre-training, and rapid decision-making, thereby establishing a mutually enhancing interplay. Moreover, we offer an in-depth case study focused on power allocation to illustrate the interdependence between AIGX and networking systems. Through this exploration, the article analyzes the significant role of GAI for networking, clarifies the ways networks augment AIGX functionalities, and underscores the virtuous interactive cycle they form. This article paves the way for subsequent future research aimed at fully unlocking the potential of GAI and networks. © 2023, CC BY.

The development of non-noble metal oxide catalysts for oxygen evolution reaction (OER) under acidic conditions is critical to sustainable energy conversion and storage. However, achieving catalytic performance comparable to that of noble metals remains a significant challenge. Herein we leverage crystal field theory and the site occupancy preferences of magnetic ions to introduce magnetic sites in a half-selective manner into the conventional spinel-structured catalyst Co 3 O 4 , thereby realizing alternating atomic hybridization within the crystal lattice. Drawing on the long-range exchange interaction in a half-ordered crystal field, bisymmetry breaking occurs thanks to the synergistic effect of the double magnetic sites, triggering a controllable spin-state transition at the active site. Meanwhile effective metal-adsorbate bonding induced by enhanced spin-orbit coupling leads to fast charge transfer and low rate-determining barrier. As a result, the spin-electron state modulated Co 4 Fe 2 MnO x delivers an OER overpotential drastically reduced by 240 mV compared to the conventional Co 3 O 4 , while maintaining outstanding stability of over 300 h at a high current density of 200 mA cm −2 . This work provides a new insight into the design of high-performance non-noble metal oxide catalysts for acidic OER applications.

In this paper, using electrodeposition technology to load ultra-low Ru onto FeCo-MOF/NF prepared by hydrothermal method. The Ru–FeCo-MOF/NF exhibits a porous morphology with numerous voids. Energy dispersive spectroscopy (EDS) elemental mapping and X-ray photoelectron spectroscopy (XPS) results confirmed that ultra-low amount of Ru was successfully doped into Ru–FeCo-MOF/NF. Benefiting from ultra-low Ru doping, small charge-transfer resistance and best reaction kinetics, the Ru–FeCo-MOF/NF exhibits small overpotential of 98 mV toward hydrogen evolution reaction (HER) and 77.5 mV toward methanol oxidation reaction (MOR) at current density of 10 mA cm −2 in potassium hydroxide (1 M) with methanol (5 M) solution. Based on excellent MOR and HER activity, Ru–FeCo-MOF/NF as a bifunctional catalyst has important application prospects in the field of hydrogen production by electrolysis of water.

In this paper, mathematical models for three types of MHD propeller are built. And they are used to achieve the most efficient propeller with the given design constraints. Based on the design result and current status of practical magnet technology, we can infer that it is very difficult for these three types of MHD propeller to be used practically.

The cascaded H-bridges with carrier phase-shift SPWM can increase the equivalent switching frequency and improve the output voltage quality. When the cascaded H-bridges topology is applied to the line-frequency inverter power supply, the bulky magnetic components limit the power density of the power supply. This paper integrates the isolation transformers and filter inductors in the power supply, and develops an optimization design method of the transformer. Through integration and optimization design, the volume power density of the transformer is increased by 69.6%, and the weight power density is increased by 44.8%.

In this paper, a method for measuring electrical conductivity of the carbon fiber sleeve is introduced. Different from traditional method using the bar, the ring shaped specimen is adopted, where eddy current is induced and flows in the closed loop. An air-gapless reactor was designed, based on this, the reactor was given a sinusoidal excitation with a certain frequency and different amplitudes. By separating the joule loss from the measured total loss, the equivalent electrical conductivity along the circumferential direction can be computed according to the theoretical formula. The result is validated by a finite element model established in Ansoft/Maxwell 3D.

To improve energy storage performance of the multi-ring RCP flywheel comprised of inner hub, tungsten alloy ring and outer retainer, optimization design process for the radial thicknesses of components and interference fit assembly is demonstrated. Radial thicknesses of these components and magnitude of interference fit are set as design parameters to construct parametric analysis model. design of experiments (DOE) technique is adopted to generate design matrix for sensitive analysis. Subsequently, radial basis function (RBF) approximation is employed to search for the optimal design considering structural integrity requirement. Finally, a proper range of the magnitude of interference fit is obtained which can not only prevent neither slippage nor separation between the inner hub and tungsten alloy ring but also ensure the safety of structural strength. In addition, it is found that to ensure a high moment of inertia and energy density, a reasonable large radial thickness of tungsten alloy ring and a reasonable small radial thickness of outer retainer are required.

Modern electronic equipment has been moving towards large scale and increased complexity. Affected by such factors as complex working environments, the performance of a large number of structures in engineering is degraded or even destroyed. Therefore, structure shape estimation is of great significance. The complexity of the structure, however, makes it impossible for a single deformation evaluation algorithm to evaluate the structure comprehensively and accurately. In this paper, a modal-approximate curve (M-AC) method, using a small amount of strain data, is proposed for block shape estimation of structures. Three typical wind load experiments are carried out on the finite element model (FEM) of the vehicle-borne active phased array antenna, and the effectiveness of the algorithm is verified. Under the wind speed of 28 (m/s), the deformation of antenna front is 104.70 mm and the estimation accuracy of the M-AC method is 87.43%, which is 16.47% higher than that of the modal approach. The results indicate that the estimated displacement is consistent well with the simulation results of the finite element method.

With the development of electronic equipment integration technology, the air demand for cooling in cabin and electronic system is increasing continuously. The ram air outlet plays an important role in the airflow system. In this paper, the three-dimensional modeling of the door-type ram air outlet and the grille-type ram air outlet is carried out. Then, the flow characteristics and resistance characteristics of ram air outlet are analyzed based on structured grid technology. The results show that the flow rate of the door panel ram air outlet is greater than that of the grille-type ram air outlet in the same size, the discharge rate of the door panel outlet is 0.3kg/s more than that of the grille-type outlet under the design condition, and the skin surface temperature at the back of the door panel outlet is 13.5K lower than that of the grille outlet. Therefore, the door-type ram air outlet has better emission characteristics and flow characteristics, which is more suitable for the aircraft in this research. This study provides a technical reference for the design of the civil aircraft. © 2020 Institution of Engineering and technology. All rights reserved.
