To automate the quality control of painted surfaces heating devices, an automatic defect detection and classification system was developed by combining deflectometry bright light-based illumination on image acquisition, deep learning models for non-defective (OK) defective (NOK) that fused dual-modal information at decision level, online network dispatching visualization. Three decision-making algorithms were tested implementation: a new model built trained from scratch transfer pre-trained...
Sheet metal forming tools, like stamping presses, play an ubiquitous role in the manufacture of several products. With increasing requirements quality and efficiency, ensuring maximum uptime these tools is fundamental to marketplace competitiveness. Using anomaly detection predictive maintenance techniques, it possible develop lower risk more intelligent approaches scheduling, however, industrial implementations methods remain scarce due difficulties obtaining acceptable results real-world...
The next generation of mobile broadband communication, 5G, is seen as a driver for the industrial Internet things (IIoT). expected 5G-increased performance spanning across different indicators, flexibility to tailor network needs specific use cases, and inherent security that offers guarantees both in terms data isolation have triggered emergence concept public integrated non-public (PNI-NPN) 5G networks. These networks might be flexible alternative well-known (albeit mostly proprietary)...
Predictive maintenance (PdM) plays a key role in the Industry since it allows optimization of schedule for proactive interventions and to take maximum advantage useful lifetime industrial assets. The reliability-centered (RCM) is based on equipment's reliability use different strategies optimize costs. With recently proposed data-driven methodology entitled generalized fault trees (GFT), possible assess equipment real-time, their actual condition. In this paper, we exploit GFT completely...
Isotherm following sensors, which are sometimes referred to as recession sensors for historical reasons, have been resurrected and modified quantify low density thermal protection system (TPS) material response. The modifications presented herein dramatically improved reliability, accuracy, data quality. Extensive research of TPS response on atmospheric entry vehicles the Department Defense was conducted in 1960s, requiring development sensor technology. only NASA Earth whose heavily...
The Mars Science Laboratory (MSL) mission is scheduled to enter the Martian atmosphere in August 2012. Aboard heatshield MSL Entry Descent and Landing Instrumentation (MEDLI) system that includes a series of embedded sensor plugs measure in-depth response thermal protection (TPS). general objectives MEDLI are assess TPS performance reconstruct aerothermal environment experienced during entry. Some specific objectives, such as measuring temperature, can be addressed with direct measurements....
A considerable part of enterprises’ total expenses is dedicated to maintenance interventions. Predictive (PdM) has appeared as a solution decrease these costs; however, the necessity end-to-end solutions in deploying predictive models and fact that are often difficult interpret by practitioners hinder adoption PdM approaches. In this work, we propose flexible architecture for recommend actions. The proposed based on containerized microservices intelligent edge devices together with hybrid...
Seeking a total automation of the existing industrial processes, manual product quality control systems have been gradually replaced by automated ones, to significantly improve efficiency and speed, ultimately, increase productivity. In this regard, an inspection system was developed in work detect classify defects on painted surfaces Bosch Thermotechnology water heaters. This comprised deflectometry-based image acquisition module, two light deep learning models built trained from scratch...
Abstract The Multi‐Objective Bike Routing Problem (MOBRP) addressed in this paper consists finding a set of good solutions that represents the trade‐off between cyclist preferences when choosing route. We propose new genetic approach to solve MOBRP (NGA‐MOBRP) with mutation operator. To test approach, we consider four conflicting criteria: safety, travel distance, time, and comfort. well‐known Nondominated Sorting Genetic Algorithm II (NSGA‐II) is also implemented context, its weaknesses are...
Abstract Integration of blockchain systems into industrial applications show promise in increasing security, trust, and transparency along the value-chain during product process tracking. However, current solutions suffer performance deficiencies, or often disregard legacy devices still operation. We propose a system built upon an IoT architecture that is secure, modular, easily scalable, deployable for fast certification manufacturing data, compatible with landscapes. First, proposed...
Chromium electrodeposition from hexavalent Cr (VI) aqueous solutions for thin films and coatings has been vastly used distinct purposes, due to the attractive appearance outstanding mechanical, wear corrosion properties of resulting coatings. Regardless, its toxicity led implementation European legislation rescript use, such as Norms Regulation on Registration, Evaluation, Authorisation, Restriction Chemicals (REACH) Certain Hazardous Substances (RoHS). Thus, a replacement VI must be found,...
With the increasing concern about sustainable means of transport, use bicycle is earning popularity. However, for cyclists, it may be a challenge to this mean transportation in an urban context, since there are plenty route choices available and each them represent different trade-off between multiple objectives, such as safety travel distance. These trade-offs depend on cyclist's experience preferences. Thus, while experienced cyclist choose shortest path source destination points, beginner...
In the evolvable manufacturing world we are moving towards systems made of small intelligent interacting units which make their own decisions independently from a centralized decision maker. System intelligence will be collective resulting large number individual decision, each one based on its local knowledge. our paper present Ubiquitous Production Systems and Enterprises (UPSE) whose foundations can found in two main scientific areas/disciplines, (1) Computing (2) Virtual Networked...
Ambient air carries hundreds of volatile compounds that can provide information about the toxicity and quality our immediate environment.
