However, not every microstructure feature impacts the underlying material property equally. Detailed knowledge about the interplay of the feature with the property generates guidelines for the design of the microstructure within the processing step. Our work shows that the electrical conductivity is clearly more affected by the alteration of certain microstructural features.

TFT technologies

Unit tests are performed in a simulated environment, which provides several advantages to the project. There is no need for additional hardware to provide inputs to the model because every input is already incorporated into the model. When modular software is eventually loaded onto hardware during integration testing, the model can simply remain a simulation or it can be used as an actual software build that is loaded onto embedded hardware. Additionally, simulated unit testing is all the more valuable because it allows you to see the inner workings of software logic prior to integration testing.

Course Materials Include:

When the adjustments are complete and the results from MIL and SIL testing are equivalent, then the development process will move on to the next stage. The digital thread improves collaboration and communication as information moves back and forth as requirements change and new insights arise. In addition, engineers can also include other considerations as they come up including cost, reliability and maintenance.

Based on the segmented 3D data, utilizing the U-NET with the hybrid training approach, we perform the curvature analysis. The Avizo 3D curvature module extracts the Gaussian and mean curvature data from the pore-copper surface. The joint probability distribution plot and the mean values of the curvatures are done with the gaussian_kde module and the NumPy package in Python, respectively. A Segmented volume of interests (VOIs) with 10 × 10 × 10 μm3 for sample HPA, HPB and NPC, exemplary for 175 °C, with the copper (gray) and pore (red) phases.

Renowned instances encompass particle swarm optimization (PSO)15, ant colony optimization (ACO)16, immune algorithm (IA)17 and genetic algorithm (GA)18. The fusion of population intelligence and machine learning has been a focal point of recent research. For example, Feng et al.19 employed PSO to fine-tune support vector machines (SVM) for hydrological forecasting. Their approach demonstrated superior predictive accuracy when compared to conventional models such as artificial neural networks (ANN) and extreme learning machines (ELM). Bezdan et al.20 innovated a hybrid population intelligence approach by enhancing the fruit fly algorithm (FFA) with the search dynamics of the firefly algorithm (FA) and opposites-based learning (OBL).

For the investigation of the microstructure evolution upon temperature, six sinter temperatures with 175 °C, 200 °C, 225 °C, 250 °C, 350 °C, and 400 °C are selected, see Fig.1a. Each reconstructed 3D dataset comprises about 450 images with an image size of 1120 × 640 pixels2 which makes an automated analysis approach indispensable, see Methods for further details regarding the image acquisition. To further explore the optimal model for haze prediction and better characterize the model's fit, this study introduces the Mean Absolute Percentage Error (MAPE), Root Mean Square Error (RMSE), and Coefficient of Determination (R2). Based on these metrics, we performed a statistical analysis of the discrepancies between the predicted results of several models and the ideal values.

All data that support the findings of this study are available from the corresponding author upon reasonable request. Three copper pastes have been developed by Dycotec Materials Ltd and Intrinsiq Materials. They consist of micro- and nanoscale size copper, solvents, organic metal precursors, and organic binders. The size of nanoparticles and microparticles is about 150 nm and approximately within a micrometer, respectively. Two other differences are the viscosity and solid content of the copper pastes. At ambient conditions and with a shear rate of 50/s, leading to different viscosities of HPA, HPB, and NPC.

Flexible and large-area electronics rely on thin-film transistors (TFTs) to make displays1,2,3, large-area image sensors4,5,6, microprocessors7,8,9,10,11, wearable healthcare patches12,13,14,15, digital microfluidics16,17 and more. This increases the cost and complexity of manufacturing TFT-based flexible electronics, slowing down their integration into more mature applications and limiting the design complexity achievable by foundries. We have designed the iconic 6502 microprocessor in both technologies as a use case to demonstrate and expand the multi-project wafer approach. Enabling the foundry model for TFTs, as an analogy of silicon CMOS technologies, can accelerate the growth and development of applications and technologies based on these devices. Due to the complexity of the process-structure-property relationship for porous materials, a single mathematical formulation from the porosity and the material parameter dependence58 is not sufficient. The microstructure can be quantified by the physical descriptor or microstructure features.

Tortuosity measurements

HIL testing is the last step before systems integration and end-to-end testing with a human in the loop. The generated code is run against the plant model on a real-time system such as dSpace. The real-time system performs deterministic simulations in situations that mimic the real world, including the physical connections to the processor, inputs and outputs, communication protocols and more. The goal of HIL testing is to diagnose issues related to communications and interfaces before going into real world testing. If the results are different, the model, code, processor, communication protocol or system architecture would need to be reviewed and adapted. Hence, the presented MVLR model can produce a highly linearized correlation with an R2 of 0.986 for model Q.

Deep learning models are widely applied for their superior learning and fitting abilities in haze prediction. Yet, they are limited by optimization challenges, long training periods, high data quality needs, and a tendency towards overfitting. Furthermore, the complex internal structures and mechanisms of these models complicate the understanding of haze formation.

Nevertheless, the number of computation units within the GPU is much higher than the number of logical control units. So, under the CUDA architecture, a simple data computation model is first constructed to avoid complex instruction flow control. Then create a large-scale threaded computing model, where the CPU is responsible for complex logic processing and system scheduling, and the GPU is responsible for massively parallel computing. As the CPU and GPU have different storage spaces, CUDA provides different levels of memory to enable threads to run independently on the GPU device (see Fig. 2). During parallel program execution, CUDA threads may access data from multiple memory spaces. Each thread has private local memory (Local Memory) that exists only for the lifetime of that thread.
