Power amplifier (PA) models, such as the neural network (NN) models and multilayer NN have problems with high complexity. In this article, we first propose a novel behavior model for wideband PAs, using real-valued time-delay convolutional (RVTDCNN). The input data of is sorted arranged graph composed in-phase quadrature ( I/Q ) components envelope-dependent terms current past signals. Then, created predesigned filter layer to extract basis functions required PA forward or reverse modeling....
As a key enabler of emerging 6G applications, mobile edge computing (MEC) improves the system performance by coordinating computation resources between devices and edge. However, energy consumption carbon emission are boosted as device number increases. This paper constructs hierarchical network-assisted task offloading architecture for Green Internet Things (IoT). Then authors propose an energy-efficient scheduling based on traffic mapping with slack-space proportional pre-allocation...
Driven by the demands of diverse artificial intelligence (AI)-enabled application, Mobile Edge Computing (MEC) is considered one key technologies for 6G edge intelligence. In this paper, we consider a serial task model and design quality service (QoS)-aware offloading via communication-computation resource coordination multi-user MEC systems, which can mitigate I/O interference brought reuse among virtual machines. Then construct system utility measuring QoS based on application latency user...
The metaverse employs globally distributed computing and communication infrastructures to construct an immersive digital world. Its continuous synchronization hyperinteractivity create a dilemma involving tremendous volumes of sensory data scarce spectrum resources. Connected automated vehicle (CAV) networks integrate onboard sensing, communication, computation, storage capabilities enhance the metaverse.

The power amplifier (PA) behavior models based on deep neural networks (DNNs) have been widely used. However, it is challenging to balance the network depth, number of neurons, and combination input terms. Accordingly, how obtain a suitable DNN model becomes problem. This letter proposes method acquire corresponding optimal structure balancing multiple aspects for PA by decoupling relationship three factors mentioned above. algorithm first chooses combinations, then utilizes inputs select...
With the development of Internet Things (IoT), there are numerous real-time applications emerging for B5G. Driven by low-latency requirement, mobile edge computing has become an important technology enhancing user experience and reducing network costs. However, power single-processor CPU is limited, it difficult to meet requirements computation-intensive applications. Besides, performance limited cell interference. In this paper, we design a user-centric Cell-Free Heterogeneous Mobile Edge...
Abstract The temperature has an important effect on mechanical behaviors of composite Y‐frame cores sandwich structure. Therefore, the in‐plane compressive this structure should be thoroughly studied before it is used in engineering structures. tests for were carried out within ranged from −70°C to 200°C. load–deformation curves, deformation modes, and failure load at various temperatures compared discussed. results revealed that closely associated with testing temperature. cryogenic caused...

Manual optimization of parameters in analog integrated circuit (IC) design is a laborious and uncertain task, with no guarantee achieving good result. This paper presents an application the blended distribution estimation evolutionary algorithm for parameter dual-output voltage reference. To enhance convergence speed effectiveness automated IC design, such as references, out-of-range (OOR) function based on performance ranking are proposed. The proposed methodology demonstrated to...
Dynamic response research of steam generator loss coolant accident (SG LOCA) is essential for the reliability and safety consideration. According to differences LOCA loading phenomena, two types loads affect SG: rarefaction wave travels through primary fluid in U-tubes, SG shakes due reactor loop(RCL) motions transmitted by loop piping, former phenomena evaluation called analysis while latter shaking analysis. This paper place particular emphasis on At present, published literatures about...
As a semi-formal model, UML sequence diagram can be widely useful for modelling and analyzing functional behaviors of developing software system. However, reasoning about decomposition composition diagrams has not been addressed adequately. The traditional method is based on the ideas from global system to local components, components are recomposed into whole according communication assumptions or other mechanisms. In this paper, we propose an event-based formal semantics present new...
Climate system is complicated and highly nonlinear, a certain condition occurs over small region could potentially propagate through space to affect remote regions. However, diagnosing such relationships challenging due the non-linearity of climate itself. In this study, we analyzed relationship between Pacific Sea Surface Temperatures (SST) anomaly that indicates El Niño dynamics Amazon basin local precipitation. We overcame traditional difficulty establishing reliable with simple linear...
