The dimensional inspection is currently consolidated as an important tool in the
improvement of manufacturing processes. The demands of quality and the requirement of parts
with complex specifications propose new challenges, such as the incorporation of integration and
interoperability concepts in measurement operations. An important issue still unresolved in the
inspection process is the dynamic management of information that requires solutions that are at
the technological forefront and contextualized within the requirements of Industry 4.0. In this
perspective, the implementation of a closed-loop inspection supports the measurement
requirements for different manufacturing processes and enables the application for different
purposes. The feedback strategy proposed in this article proposes an alternative as a solution to
integrate the inspection results of a part within a digital manufacturing chain based on STEP-NC
(STandard for the Exchange of Product model data - Numerical Control). The mechanisms for
acquisition, processing, and analysis of information, and the control architecture that complement
the feedback strategy is exposed.

Small scale industries produce certain products depending on the type of industry they have established. If these small scale industries decide to become medium scale certain changes have to be incorporated in plant layout to meet certain requirements. Certain changes include change in layout design, introducing new machines and equipments in the industry in order to produce new component .To implement these changes in the company we have to get information regarding the new component the company would produce based on this information we have design new plant layout. The purpose of this project is to plan a suitable plant layout which could meet company requirement. To design a new plant layout we are using Delmia as the simulation software. DELMIA Production System Simulation allows the process planner to validate the manufacturing system dynamically. Product flow and operation time, as well as scheduled maintenance and random equipment failure events, are simulated to help the planner understand how they will impact the systemās capacity. Process planners can determine if changes to the system are needed to achieve the desired production demands.

It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
Ā
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
Ā
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
Ā
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CAD data requirements for inspection
To perform the inspection it is necessary to
obtain information from the model product in
addition to the project requirements. In the
proposed application scenario the part
design is developed based on features.
Feature-based part modeling technology is
the primary component in integrating the
processes associated with the product life
cycle of a part. The STEP standard mainly
uses this technology to provide a neutral,
interoperable format for the exchange of
product information.
Compensation strategy
The error compensation strategy uses the STEP
standard data model to integrate the manufacturing
and inspection processes. The measurement system
acquires data of the geometry of the part
manufactured in several points located in dierent
dimensional planes, with these values the control
system reconstructs the surface, analyzes and
processes the results to quantify the error, identify the
causes and generate the compensation. The expert
system in charge of processing a large part of the
information bases its operations on structured
knowledge within a set of rules aimed at maximizing the eciency of the process. The compensation
in the process is generated directly in the program sent to the control system of the machine tool,
which contains the execution routines to machine a new part. Inspection is repeated after
machining, this reduces the error in each closed-loop system interaction.
Closed-loop inspection
The control strategy within the closed-loop inspection seeks to compensate the input data
to the control system of the CNC with the results of a comparison between the design
nominal and the inspected part to meet the quality requirements of the project. The Figure
2 presents the control scheme for the integration model. The compensation system is in
charge of generating the orders sent to the CNC controller of the machine tool, adjusting
the code of the nominal part with the necessary changes to satisfy the requirements. The
CNC control system of the machine tool executes the numerical commands for machining
the part. The inspection system, in charge of acquiring data of the manufactured part,
plans, executes and analyzes the measurement results.
Conclusion
The dimensional and geometric inspection allows implementing strategies to perfect the
manufacturing processes using correctly the obtained information. The feedback strategy
proposed in the article avoids the loss of information produced by format changes between
systems because it uses a neutral data structure with homogenized syntax and semantics for diferent processes of the one-piece
manufacturing life cycle.Automated operations, optimization techniques, and expert systems for decision-making can be easily implemented.
