Surrogate models are widely used in simulation-based engineering design and optimization to save the computing cost. The choice of sampling approach has a great impact on metamodel accuracy. This article presents robust error-pursuing sequential called cross-validation (CV)-Voronoi for global metamodeling. During process, CV-Voronoi uses Voronoi diagram partition space into set cells according existing points. error behavior each cell is estimated by leave-one-out (LOO) approach. Large...
In dealing with the expensive multiobjective optimization problem, some algorithms convert it into a number of single-objective subproblems for optimization. At each iteration, these conduct surrogate-assisted on one or multiple subproblems. However, may be unnecessary resolved. Operating such can cause server inefficiencies, especially in case To overcome this shortcoming, we propose an adaptive subproblem selection (ASS) strategy to identify most promising further modeling. better leverage...
The ultra-fine grain structure of Al–Zn–Mg–Cu alloy was prepared by equal channel angular pressing (ECAP) and post cold rolling (CR) combined deformation process. effect different on the microstructure, microhardness corrosion behavior ECAP were studied. results show that with increase deformation, dislocation density increased, second phases deformed obviously refined. Grain refinement mainly due to gradual transformation some subgrain boundaries low angle (LAGBs) alloys into high (HAGBs),...
This paper presents a compact-size, low-cost smart antenna with electronically switchable radiation patterns, and reconfigurable polarizations. can be dynamically switched to realize three different polarizations including two orthogonal linear one diagonally polarization. By closely placing several parasitic elements around the driven antenna, beam switching achieved in any of polarization states. In this design, square patch simple feeding network is used as element. The element composed...
A thin radar-infrared stealth-compatible structure with reflectivity below −10 dB in the whole radar X wave band and infrared emissivity less than 0.3 region of 8 μm–14 μm is reported. The designed consists metallic frequency selective surface (MFSS), resistive (RFSS), metal backing from top down, it only 2.1-mm thick. MFSS made up some divided low copper films, RFSS a capacitive array square patches. They are placed close together, working as an admittance sheet because mutual influence...

A main challenge for radar-aided millimeter wave (mmWave) vehicle-to-infrastructure (V2I) communication application, is that it requires mitigating the mutual interference between vehicular radar and operating at same frequency bands. This paper considers joint design of multiple-input multiple-output (MIMO) transmit waveform receive filter bank road side unit (RSU)-mounted in a spectrally crowded V2I environment. With criterion maximizing average signal-to-interference-plus-noise ratio...
Computer simulations have been increasingly used to study physical problems in various fields. To relieve computational budgets, the cheap-to-run metamodels, constructed from finite experiment points design space using of computer experiments (DOE), are employed replace costly simulation models. A key issue related DOE is designing sequential achieve an accurate metamodel with as few possible. This article investigates performance current Bayesian sampling approaches and proposes adaptive...

Comparative results on eight representative benchmark and an engineering application...
In order to scale standard Gaussian process (GP) regression large-scale datasets, aggregation models employ factorized training and then combine predictions from distributed experts. The state-of-the-art models, however, either provide inconsistent or require time-consuming process. We first prove the inconsistency of typical aggregations using disjoint random data partition, present a consistent yet efficient model for GP. proposed inherits advantages aggregations, e.g., closed-form...
