A First Step Towards AI for MBSE: Generating A Part of SysML Models From Text Using AI

•

1 like•754 views

The document presents a first step towards using artificial intelligence to assist with model-based systems engineering (MBSE). It trains a named entity recognition model using 100 sentences to identify actors and use cases from text. This could help accelerate early MBSE adoption phases like creating model libraries. However, more work is needed to develop a coherent foundation and enhance the text-to-model tool. Combining AI and MBSE competencies may enable generating partial SysML models automatically from textual requirements or specifications.

This document provides an overview of transformers in computer vision. It discusses how transformers were originally developed for natural language processing using attention mechanisms instead of recurrent connections. Vision transformers apply this approach to images by treating patches as tokens and using self-attention. Early vision transformers achieved strong results on image classification tasks. Recent developments include Swin transformers which use shifted windows to incorporate positional information, and models that combine convolutional and transformer architectures. Transformers are also being applied to video understanding tasks. The document explores different transformer architectures and applications of vision transformers.

The objective of the Physical Architecture in defining the “real” concrete components that comprise the system. To start the Physical level based on the Logical level, Capella proposes transitions similar to those that we used when we went from the Operational Analysis to the System Analysis, then from the System Analysis to the Logical Architecture. Thus, it can be created as many Physical Functions as Logical Functions, by also keeping the Functional Exchanges and Functional Chains.

ASIC DESIGN FLOW

Purvi Medawala

This document outlines the typical ASIC design flow process. It begins with specification where the features and functionalities of the ASIC are defined. This is followed by RTL coding to develop the logic functionality in a hardware description language. Simulation and synthesis then convert the RTL into a gate-level netlist. Pre-layout timing analysis checks for timing issues. Then automatic place and route lays out the design on the chip. Back annotation adds layout parasitic information. Post-layout timing analysis checks for real timing violations. Logic verification confirms correct functionality. The final tapeout step sends the design for fabrication if all checks pass.

Classical force fields as physics-based neural networks

aimsnist

1. The document discusses classical interatomic potentials and machine-learning potentials for atomistic simulations. It presents a new physically-informed neural network (PINN) potential that combines the accuracy of neural networks with the transferability of physics-based potentials. 2. As an example, the document develops a PINN potential for aluminum that accurately reproduces density functional theory energies and various aluminum properties beyond the training data. 3. The PINN potential is shown to have better transferability and predictiveness compared to a purely mathematical neural network potential. This makes PINN potentials a promising next-generation approach for efficient and accurate atomistic simulations.

The document summarizes a research seminar presentation on using transformers for image recognition without convolutional biases. It discusses how a pure transformer architecture called Vision Transformer (ViT) can achieve state-of-the-art image classification performance when pretrained on large datasets. ViT works by splitting images into patches and treating the sequence of patch embeddings with a standard transformer. Experiments show ViT outperforms convolutional models in performance per computation and can learn spatial representations without explicit inductive biases. While limited to classification, ViT shows potential for vision tasks if pretrained self-supervision and model extensions are improved.

IJECEIAES

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

IJECEIAES

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

gerogepatton

As digital technology becomes more deeply embedded in power systems, protecting the communication networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3) represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities. Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network (CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to train and test our model. The results of our experiments show that our CNN-LSTM method is much better at finding smart grid intrusions than other deep learning algorithms used for classification. In addition, our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection accuracy rate of 99.50%.
