Industry 4.0 and AI Best Practices - Connected World

#artificialintelligence

Here's an attention-grabbing idea: Deploying cellular-enabled Industry 4.0 solutions can generate a 10-20x operational cost-savings ROI (return on investment) over the course of five years. This is according to a joint research study from ABI Research and Ericsson. The research also suggests Industry 4.0 solutions can generate up to 8.5% in operational cost savings, which, for a factory or industrial site, can equate to an operational cost savings of up to $600 per square meter per year. Industry 4.0, also known as the fourth industrial revolution, is the idea that connectivity, automation technologies, and digitization are creating the fourth major revolution in the business of manufacturing. Thanks to trends like leveraging the IoT (Internet of Things), including wireless networking and sensors to collect machine data and enable predictive maintenance, as well as 3D printing, robots and cobots on the factory floor, machine learning and AI (artificial intelligence), 5G, and digital twins, among other trends, the Industry 4.0 market is projected by MarketsandMarkets to reach almost $157 billion by 2024. A big part of Industry 4.0 is the use of AI technologies to enable smarter machines that can take on tasks like self-monitoring and diagnosis autonomously.


Deep Active Learning for Solvability Prediction in Power Systems

arXiv.org Machine Learning

Traditional methods for solvability region analysis can only have inner approximations with inconclusive conservatism. Machine learning methods have been proposed to approach the real region. In this letter, we propose a deep active learning framework for power system solvability prediction. Compared with the passive learning methods where the training is performed after all instances are labeled, the active learning selects most informative instances to be label and therefore significantly reduce the size of labeled dataset for training. In the active learning framework, the acquisition functions, which correspond to different sampling strategies, are defined in terms of the on-the-fly posterior probability from the classifier. The IEEE 39-bus system is employed to validate the proposed framework, where a two-dimensional case is illustrated to visualize the effectiveness of the sampling method followed by the full-dimensional numerical experiments.

PrintSyst launches pre-printing analysis tool powered by artificial intelligence

#artificialintelligence

PrintSyst.ai has launched its latest proprietary artificial intelligence (AI) engine which aims to improve the consistency and reliability of 3D printed parts. The 3DP AI-Perfecter is a pre-printing evaluation tool and has been designed to allow companies in the aerospace, defence and automotive industries to produce additively manufactured parts with greater repeatability and reduced labour, time and cost. It believes analysis of parts before the physical 3D printing to be crucial and a process that requires highly-skilled engineers to carry out, while also baring significant risks to a company's reputation should errors be made. PrintSyst has therefore spent the last couple of years focusing on artificial intelligence and leveraging the technology to create a platform that, the company claims, has enabled instant, automatic and accurate pre-printing part analysis that can save up to 99% of the preparation time and cost. "It is a scalable tool and using it is extremely user friendly and simple," commented Itamar Yona, PrintSyst's CEO. "We support multiple 3D printing technologies and our customers enjoy automatic AI-based printing recommendations.


Machine learning can replicate toolpaths in 3D printed fiber reinforced parts – IAM Network

#artificialintelligence

A research team from the NYU Tandon School of Engineering has published a study that uncovers vulnerabilities in the production of carbon fiber reinforced 3D printed parts. The vulnerability is not related to the strength of the parts, but rather in protecting their toolpaths and preventing counterfeit parts. The ability to 3D print carbon fiber reinforced polymers is creating numerous exciting applications across the aerospace and industrial sectors, among others. The materials are advantageous for many reasons, but their strength-to-weight ratios and durability are most notable. However, the process of 3D printing these materials, and specifically the extrusion-based process, can actually reveal the construction of the part and its design.


Reverse engineering of 3-D-printed parts by machine learning reveals security vulnerabilities

#artificialintelligence

Over the past 30 years, the use of glass and carbon-fiber reinforced composites in aerospace and other high-performance applications has soared along with the broad industrial adoption of composite materials. Key to the strength and versatility of these hybrid, layered materials in high-performance applications is the orientation of fibers in each layer. Recent innovations in additive manufacturing (3-D printing) have made it possible to finetune this factor, thanks to the ability to include within the CAD file discrete printer-head orientation instructions for each layer of the component being printed, thereby optimizing strength, flexibility, and durability for specific uses of the part. These 3-D-printing toolpaths (a series of coordinated locations a tool will follow) in CAD file instructions are therefore a valuable trade secret for the manufacturers. However, a team of researchers from NYU Tandon School of Engineering led by Nikhil Gupta, a professor in the Department of Mechanical and Aerospace Engineering showed that these toolpaths are also easy to reproduce--and therefore steal--with machine learning (ML) tools applied to the microstructures of the part obtained by a CT scan.


Graph Neural Networks for Leveraging Industrial Equipment Structure: An application to Remaining Useful Life Estimation

arXiv.org Machine Learning

Automated equipment health monitoring from streaming multisensor time-series data can be used to enable condition-based maintenance, avoid sudden catastrophic failures, and ensure high operational availability. We note that most complex machinery has a well-documented and readily accessible underlying structure capturing the inter-dependencies between sub-systems or modules. Deep learning models such as those based on recurrent neural networks (RNNs) or convolutional neural networks (CNNs) fail to explicitly leverage this potentially rich source of domain-knowledge into the learning procedure. In this work, we propose to capture the structure of a complex equipment in the form of a graph, and use graph neural networks (GNNs) to model multi-sensor time-series data. Using remaining useful life estimation as an application task, we evaluate the advantage of incorporating the graph structure via GNNs on the publicly available turbofan engine benchmark dataset. We observe that the proposed GNN-based RUL estimation model compares favorably to several strong baselines from literature such as those based on RNNs and CNNs. Additionally, we observe that the learned network is able to focus on the module (node) with impending failure through a simple attention mechanism, potentially paving the way for actionable diagnosis.


Avular designs custom drones from the ground up with 3D printing – IAM Network

#artificialintelligence

Source: AvularSince its founding six years ago, Eindhoven, Netherlands-based Avular has built aerial drones for industrial and agricultural clients. Business was good, but for the first several years, there was a frustrating limitation: "We started to get a lot of customers asking, 'Can I do this with a drone? Can I do that with a drone?'" said Albert Maas, co-founder and CEO of Avular. "We often had to say, 'I'm sorry, it's too complicated to take this very niche, dedicated system and build something else with it.'" Two years ago, Avular decided to flip that script.
