Before evaluating the quality of compliance between the observed and simulated behaviors, model verification is necessary. Model verification is the confirmation that the virtual prototype represents the system model within the specified limits of accuracy. With this realized and understood, the level of agreement of the observed and simulated behaviors is the essence of the model validation step. We conduct FIB-SEM tomography to image three different porous copper materials.

Data availability

Today, model-based development as a concept has been used to solve challenges across multiple industries. Model-based development was developed to solve this system of systems, multi-team, multi-organizational communication challenge. It was a paradigm where models become the central artifact, independent of the development process. It may be useful to break out the implementation and project testing section of the model-based design flow and illustrate the iterative process to build a credible model.

Microstructure feature importance and mathematical relationship of microstructural features and electrical behavior

By embracing cutting-edge technologies like computer-aided design (CAD) and 3D printing, engineers now have the ability to visualize, iterate, and perfect designs in a digital realm before bringing them to life. Any system can be modeled if you have sufficient data and understand how the data behaves and interacts within a system. With all the advantages that digital engineering offers it’s no surprise to see it being embraced across numerous industries. Expect to see increased MBSE job reqs, digital engineering lectures, seminar opportunities, and aspirations for adopting model-based approaches in the coming years.

Data sources and pre-processing

In CUDA, the data transfer bandwidth between the computer's main memory and GPU memory is much smaller than that of GPU memory. When processing small-scale data, the kernel program runs in a shorter time, while the inter-memory data transfer can take up a lot of time. 6, PSO-CPU-GPU asynchronous parallel SVR model has improved prediction accuracy for test samples as the scale of data increases. At large data sets, the PSO-CPU-GPU asynchronous parallel SVR model's computing time is significantly better than the PSO-SVR model's running time (see Fig. 7). The data transfer time between the computer's main memory and GPU memory takes up a large portion of the time.

However, for longer periods of missing data, linear interpolation may introduce significant errors due to the extended duration of absence. After the aforementioned processing, the data used in this study is highly reliable. To enhance the efficiency of data processing and facilitate fair comparison across different datasets, all experimental data in this paper was normalized and mapped to the [0,1] interval.

The current mode of operation jeopardizes the numerous application possibilities for thin-film electronics. Different applications require distinctive design strategies and know-how, leading to the need for an increased number of designers in these technologies. Moreover, the thin-film transistor (TFT) technology affordability of the fabless design groups and companies will be very crucial in the success towards the increasing application window. Explore Simulink, an environment for multidomain simulation and Model-Based Design for dynamic and embedded systems. Model-based systems engineering (MBSE) is a methodology that uses models to support the entire lifecycle of a system, from conception and design to verification and validation activities, through to decommissioning.

Model-Based Definition (MBD) empowers engineers to go beyond these limitations and embrace a digital realm where designs are visualized, iterated, and refined with unprecedented precision. Data modeling is the process of creating a visual representation of either a whole information system or parts of it to communicate connections between data points and structures. By enabling more efficient resource allocation, reducing waste and facilitating the design of more energy-efficient systems, MBSE can help aid sustainable development goals.

The presented work indicates that the microstructure can be reconstructed synthetically for an allocated conductivity with significant quality, especially utilizing the DDPM. Clearly for the synthetic generation of the materials microstructure it is shown that the DDPM is superior to the cGAN model. The inferiority of cGAN might originate from its architecture prone to unstable training and mode collapse17. Such generated reconstructed synthetic images can be further utilized for morphological analysis16,60,61. In particular we validate the model performance by comparing the evaluated relative density, specific perimeter, as well as shape index for the real and synthetic microstructures in relationship to the sinter temperature, see Fig. Further, we extract the R2 for the three descriptors individually, as well as the average of R2 for all three physical descriptors, see Table 3.

Design and Analysis of a Symmetric Overconstrained Compliant Tilt/Tip Stage Based on a Hybrid Transmission Ratio Model

These results demonstrate the viability of transistor technologies on flexible substrates for serving a broad range of applications beyond their traditional display and imager consumer products. The integration density is the highest for the flex IGZO implementations, which can be attributed to the best photolithography resolution and the available extra metallization layers used enabling over-the-cell routing. This TFT technology will, therefore, enable the highest density circuits for flexible IoT applications or for hybrid circuits combining Si CMOS and high-density IGZO electronics.

This requires four transistors and one extra power rail to realize an inverter. This is different from the original MOS devices in the 1970s, in which local doping profiles can yield enhancement and depletion devices. The used circuit topology at that time is also depicted in Supplementary Fig. 1, which is an interesting logic style imposing fewer transistors for complex gates, even compared with CMOS inverters, at the cost of static power consumption. A two-input NOR gate uses three transistors for the depletion-load nMOS logic style, six n-type IGZO transistors for the pseudo-CMOS implementation and four LTPS complementary transistors. This business model succeeds when design requests and modifications remain relatively simple and fall within the scope and expertise of current design and application teams.

Electrical relays built into ladder-like networks were one of the first discrete control devices to automate an entire manufacturing process. Based on the segmented image data utilizing the U-NET with the hybrid training we perform the curvature analysis. The shape index used for the analysis of the real and synthetically reconstructed image relates to the local curvature measurement. The analysis is performed by utilizing the shape_index module in the python’s scikit-image library. The parallelization of the kernel function matrix is calculated in a similar way to the matrix–vector multiplication operation. Matrix A consists of m sample vectors of 1 × k dimensions, matrix B is a transpose of matrix A, and the kernel function matrix is matrix C of m × m dimensions.

These metrics represent the aggregate performance of each model across the 30 independent trials. Additionally, we recorded the training and prediction times under the support of swarm intelligence algorithms. These temporal metrics reflect the average duration consumed by SVR and the combined CPU-GPU-SVR during each training and prediction process. Through these comprehensive assessments, our study thoroughly examines the performance and efficiency of the proposed model. The evaluation of the microstructure features, their physical analysis, as well as their correlation to the material property display crucial ingredients for accelerated material design.

Utilizing the MATLAB Executable (MEX) interface, we seamlessly integrated our custom CUDA implementation with the MATLAB environment. The paper employs a heterogeneous parallel computing architecture that leverages computational resources of both Central Processing Units (CPUs) and Graphics Processing Units (GPUs). This architecture offers efficient computation for large-scale datasets of environmental, meteorological, and pollutant emission data.

A modeling language is a common terminology for clearly communicating an abstract idea that the model captures. A few system-modeling languages exist, including general-purpose languages such as the Systems Modeling Language (SysML) and Unified Modeling Language (UML), as well as specialized languages such as Architecture Analysis Design Language (AADL). Although SysML and UML are not mathematically formal, a valid model requires that the modeling language's rules for entities and relationships be followed. SysML has strict syntax and rules for relationships and connections between elements, which helps to avoid ambiguity. If a model is well built, several types of standard SysML diagrams can be dynamically simulated, and at least one type of SysML diagram can be mathematically simulated. Three-tier architecture separates applications into three logical and physical computing tiers.

Compared to other air pollutants, PM2.5 and other respirable particles not only have a serious impact on the quality of the atmosphere but also pose a significant threat to human health2,3,4. Therefore, in the case of frequent haze pollution events, scientific and effective PM2.5 prediction and early warning are very necessary. It helps to adopt timely and effective response methods to reduce the impact of smog pollution5,6,7.
