LMI based nonlinear Iterative Learning Control for uncertain discrete repetit...NAAR Journal
The problem encountered in this paper is to design a robust, feedback-based improved control system for the plant that involves systematic uncertainty. This paper proposes a fault estimation algorithm based on iterative learning control. This algorithm is constructed through an optimization function to prove the robustness and convergence of the algorithm. Through linear matrix inequality (LMI), the observer gain matrix and iterative learning parameter matrix in the algorithm are solved. The two comprehensive parameters in LMI represent the parameter selection in the two specifications to make selected adjustments in learning and control. A numerical example shows the improvement process and the effectiveness of these methods. Through LMI techniques, we have obtained satisfactory results and controller stability and robustness against fault-tolerant control. Lastly, the simulation results show the effectiveness and accuracy of the proposed algorithm.

Experimental Investigation and Analysis A Mechanical Properties of Hybrid Pol...IJRES Journal
The hybrids composite has emerged and have the potential reinforcement material for composites and thus gain attraction by many researchers. This is mainly due to their applicable benefits have they offer low density, low cost, renewable, biodegradability and environmentally harmless and also comparable mechanical properties with synthetic fiber composites. In the project natural fiber and glass hybrid composites were fabricated by using epoxy resin combination of hand lay-up method and cold press method. Specimen was cut from the fabricated laminate according to the ASTM standard for different experiments for tensile test, flexural text, and impact test. A significant improvement in tensile strength was indicated by the woven fiber glass hybrid composites. In this hybrid composite laminates banana-glass-banana (BGB) and glass-banana-glass (GBG) exhibit higher mechanical properties due to chemical treatment to natural fibers. So, the hybrid composite material shows the highest mechanical properties. This High performance hybrid composite material has extensive engineering applications such as transport industry, aeronautics, naval, automotive industries.
Economic pressures and competition have created a need for superior performance and multifunctional properties of materials. The ever-increasing demand for new product properties makes it challenging to achieve the required features when using traditional materials. Therefore, new material combinations (i.e. hybrid or composite materials) are intended to meet these challenges. Composites and hybrid materials are new material combinations which can provide added value for existing products or create novel multifunctional properties.
This thesis aimed at fabricating and modifying thin-film composites (TFC) by using various coating technologies. Moreover, the target was to tailor the permeability or to create anti-fouling performance. Inorganic, inorganic-organic and organic coating layers were made by atmospheric plasma deposition, sol-gel, atomic-layerdeposition (ALD) or polyvinyl alcohol (PVA) dispersion coating methods. Coatings were deposited using either roll-to-roll or batch process.
The scientifically novel contribution of this thesis is as follows. The thesis contributes to the development of novel TFC structures using various coating methods. The novel TFC structures provide new alternatives or improvements for the existing barrier materials in food packaging. In addition, the developed anti-fouling coatings tackle the critical challenge of membrane fouling and introduce new low-fouling TFC membranes for water treatment.
A Study on Mechanical Properties of E-Glass Polypropylene Epoxy and S-Glass P...ijtsrd
There are basic two phase of composite material, in which one is known as matrix material and another one is called reinforcing material. The reinforcing material is embedded over matrix material. The matrix material is continuous phase and reinforcing is discontinuous phase. The reinforcing phase is much harder than matrix phase. In composite material matrix phase removes the stresses between reinforcing phase and also protect from mechanical and environmental damage. The function of reinforcing material is to improve mechanical and thermal properties of composites. Composite are hybrid of two or more material such as reinforced polymer, metal or ceramics. The aim of the present work is to fabricate E-glass epoxy composite and S-glass epoxy composite with polypropylene as filler material. The fabricated laminates are then tested for mechanical properties with varying percentage of filler material. The results obtained for E-glass epoxy composite and S-glass epoxy composites are then compared. The composites with optimum results are recommended. Karthik A. S | Dr. S. V.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
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.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
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.
