Herein, we develop a methodology capable of understanding this relationship for differently processed porous materials. We utilize a multi-method machine learning approach incorporating tomographic image data acquisition, segmentation, microstructure feature extraction, feature importance analysis and synthetic microstructure reconstruction. Accurate and timely PM2.5 concentration prediction is crucial for air quality management and public health. High-quality forecasts provide a scientific basis for air quality alerts and guide healthy public travel. Addressing this critical issue, our study introduces an efficient PM2.5 prediction model. The model is based on a high-efficiency code that we developed specifically for the SVR algorithm using the CUDA, which has significantly improved the execution efficiency of the algorithm.

Support
Model based development asks for requirements to be in a database where each requirement is an object and a direct derivative of the overall product requirements. Requirements must flow down from the product level requirements to requirements for the individual systems, smaller sub-systems and components. They must also be detailed enough to satisfy the engineering methodology that the team will follow. It must be clear which particular requirements impact which components and in turn, which components are assigned to each requirements. This digital thread is critical in providing a good understanding and accounting for the interwoven relationships and interdependencies.
Model-Based Design: A Simplified Approach to Systems Development
Deep generative models exhibit the ability to create complex structures11,12. Various generative adversarial network (GAN)-based architectures have been developed in recent years targeting specific problems, e.g., X-ray image augmentation13, or molecular design11. Although GAN shows high potential for microstructure prediction14,15,16, there are challenges concerning the stable training and mode collapse, causing serious problems when certain descriptors need to be extracted from the image data17.
How MBD is Changing the Game
MBSE can also be implemented incrementally, so that it is easy to track and organize projects as they expand. It can be valuable across digital engineering and other engineering disciplines. Companies in the telecommunications sector use MBSE to design and manage complex network systems. This includes the development of infrastructure for emerging technologies like 5G, where MBSE helps in optimizing network layouts and ensuring reliable, high-speed communications.

We observed a 42% yield of the Flex IGZO 6502 in Pragmatic technology with an unoptimized design for yield. We did not focus on any design for manufacturing approach to increase the yield figure as it was out of scope for our research. The yield has been determined by characterizing 104 chips across three wafers. A more thorough analysis of yield figures in Pragmatic technology as a function of chip complexity has been studied recently11. Similarly, for LTPS, we have measured 100 samples over several GEN3.5 plates and achieved a yield of 89%. Both chips show the key advantages of the multi-project wafer concept for both wafer-based and plate-based technologies.

Among all the compared models, the standardized value of PSO-CPU-GPU-SVR exhibited the highest error stability. The absolute deviation of the predicted value from the actual value is small, meaning that PSO-CPU-GPU-SVR can effectively cope with mutation data. The 6502 processor was one of the first commercial microprocessors introduced in 1975 and integrated into many products of the 1980s, such as the Nintendo Entertainment Systems, the Commodore 64 and the Apple II (ref. 25). The original version, fabricated in an 8-µm nMOS-only technology, consists of 3,510 enhancement-mode transistors and 1,018 depletion-load pull-up transistors, adding up to 4,528 devices. The microprocessor had an 8-bit data bus and 16-bit address bus, operating at 1 MHz. Owing to the legendary nature of this processor and all its ground-breaking aspects in application and microprocessor research from that time onwards, we have selected this chip to use as a vehicle to demonstrate the foundry mode with TFTs.

Each input and output signal of the 6502 chip is accompanied by an inverting level shifter. This is essentially a resistor-load MOSFET (metal-oxide-semiconductor field-effect transistor) inverter with operational amplifier buffers, situated on both the DUT and FPGA sides. The supply voltage of the level shifters is equal to the VDD of the DUT but connected with a separate power supply to enable accurate extraction of the power consumption of the individual 6502 chip.

In the end, companies were not just designing what the final product will be. The number of teams that worked to bring a product to market also started to increase. For example, in automotive, the typical OEM started to have thousands of engineers across hundreds of Tier 1 and Tier 2 suppliers all working on a single vehicle. Developed the image analysis workflows and accelerated material platform under supervision of R.B. Further, we investigate the pore-copper interface evolution upon sintering using the Gaussian curvature G and mean curvature M47. Both curvatures classify the local surface geometries with their joint distributions48.
All these benefits lead to less time spent on design and more time spent on making actual products, which ultimately means more time making money. Likewise, inherent to 2D models is the potential for errors and misinterpretation during the translation process. MBD eliminates this risk by embedding all the necessary information directly into the 3D CAD model. The ability to seamlessly communicate design intent and product specifications plays a critical role in achieving customer satisfaction and reducing errors. These drawings have been used by Engineering, Manufacturing, and other users to communicate design form and fit information required to drive manufacturing processes. In today’s fast-paced manufacturing industry, the need for increased efficiency, accuracy, and innovation is more significant than ever before.
When σ → ∞, although the regression accuracy of the training samples is high, the generalization ability is poor, i.e., the prediction accuracy of the test samples is low. In this study, we chose the PSO algorithm over other swarm intelligence algorithms to accelerate the parameter optimization of SVR. Known for its simple structure and fewer parameters to adjust, the PSO algorithm is easy to understand and implement25.
This eliminates the need for separate documents or drawings, streamlining communication and ensuring consistency throughout the entire product lifecycle. Model-based definition offers a new way of thinking about and creating products. It enables seamless integration with cutting-edge technologies like computer-aided design (CAD) and 3D printing, making ideas come to life faster and more accurately. Gone are the days of relying solely on traditional 2D formats and passing papers from design to the shop floor, hoping for a seamless transition. However, even today, many companies continue to use 2D design because it is familiar, comfortable, and has a lower initial cost.
The LTPS chip has been outsourced by the foundry interface PanelSemi and was manufactured on a GEN3.5 plate. The IGZO technology has two extra routing layers available enabling over-the-cell routing, whereas LTPS has a limitation of one extra metal. More process information on the IGZO transistor is provided in a previous work9.
A comprehensive study is performed based on FEA model to validate the influence of a particular configuration on parasitic motion and decoupling effect. A prototype stage is 3D printed and experimentally tested, which confirmed the predictions of the analytical hybrid model. In addition, further analysis was conducted to examine the static mechanical characteristics and parasitic behavior of the stage.
