This document reviews the effect of waste carpet fibers and palm oil fuel ash on self-compacting fiber reinforced concrete. It first provides background on palm oil fuel ash and waste carpet fibers, which are agricultural and industrial byproducts, respectively. It then summarizes several studies that have investigated using these materials in concrete. The studies found that palm oil fuel ash can replace cement in self-compacting concrete and improve strength and durability over time. Waste carpet fibers were shown to increase flexural and tensile strength when added to concrete. Combining waste carpet fibers and palm oil fuel ash in self-compacting concrete resulted in improved strength and durability characteristics while providing an environmentally-friendly use for these wastes.
Experimental study on young’s modulus of f.r.c with bottom ashIJARIIT
The experiment investigation has been conducted on hybrid fibre reinforced concrete (combine of hooked end
polyolefin & steel fiber) get the volume of aggregate fibre 0.6%, 1.1% and 1.3% were readied Workability conditions like
blending, compaction & curing conditions. To adding of uniformly dispersed fibre to concrete will give fitness to the structure
and improve its dynamic, static properties. The cylinder dimensions are 150mmX300mm.The experiment result shows that the
concrete strength of steel fibre with the addition of decrease to PCC. The Young’s Modulus of samples increases with the
amounts of steel fibers in the concrete mix. The form of concrete in which fibres are added is called as FRC. The addition extra
than one or two fibres in the concrete is Called as HFRC. Fibres can be used in tension members in the structures because the
structure will be strongest in compression and weakest in tension members. Here Steel fibre & polyolefin fibre are used as Hybrid
fibres in HFRC. A trial was directed out to ponder the impacts of steel fiber and polyolefin fibre in various extents in concrete.
Compressive strength tests were conducted to know the properties of hardened concrete. The experiment also aimed to study the
capacity of BA as a fine aggregate in concreting mix. Bottom ash is a scrap material available in industries like thermal power
plants. Fiber expansion supposedly enhanced an expansion in compressive quality and ductility respectively. The fine aggregate
is replaced by 15% of bottom ash. The Final Results of this experiment showing the percentage of hybrid fibres it the maximum
performance of the concrete. Adding of HF generally energy absorbing an increases value of strength. The Young’s modulus of
concrete is a very critical factor in the concrete to elastically deform. The whole laboratory experiments were conducted in Malla

Experimental Study on Composite Concrete RC Frame Structure using Sisal Fibreijtsrd
This project aims to compare the mechanical properties of Sisal fiber in the improvement of load carrying capacity of concrete structure in different layers. Beams and columns may be strengthened in flexure through the use of sisal fiber bonded to their tension zone using epoxy as a common adhesive. Due to several advantages of sisal fibre wrapping over conventional techniques used for structural repair and strengthening. In our project is study about load carrying capacity of an RCC frame wrapped with sisal fiber. An experimental study is to predict the maximum load carrying capacity, deflection of the composite RCC structure. Finally the results are compared with conventional framed structure, which is suitable for strength and rehabilitate the concrete structure. P. Vanmathi | A.

Effects of coconut fibers on the properties of concreteeSAT Journals
Abstract
The materials chosen for structural up gradation should not pollute the environment and endanger bioreserves. They should be accessible to the ordinary people and be low in monetary cost. Coconut fiber is an abundant, versatile, renewable, cheap, lignocellulosic fiber and more resistant to thermal conductivity. The aim of investigation is to study the possibilities to use the coconut fiber in addition to the other constituents of concrete and to study the strength properties. A literature survey was carried out, which indicates that the detailed investigation of coconut fiber concrete is necessary. In the present study the deformation properties of concrete beams with fibers under static loading condition and the behavior of structural components in terms of compressive strength for plain concrete(PC) and coconut fiber reinforced concrete(CFRC) has been studied.
The testing of various material constituents of concrete was carried out according to the Indian Standard specifications. To identify the effects on workability and mechanical strength properties due to the addition of these coconut fibres, workability tests such slump, vee – bee, compaction factor test, Flow table tests, and the mechanical strength tests on standard specimens such as compressive strength, split tensile strength, modulus of rupture were conducted on the different aspect ratio. The standard cubes, cylinders and beams for conventional concrete and coconut fiber reinforced concrete were prepared and tested under compression testing machine and flexure testing machine respectively. The suitability of CFRC as a structural material is studied, in comparison with conventional concrete.

Use of Fiber is one of the vital and emerging trends in Construction Technology. Fiber can be considered as an alternative in the use of an air entraining agent providing sufficient freeze thaw protection and moreover as a reinforcing material. Fiber reinforced materials are composite materials that typically consist of strong fibers embedded in resin matrix. It is a composite obtained by adding a single type or a blend of fibers to the conventional concrete mix. The fibers provide strength and stiffness to the composite and generally carry most of the applied loads. The matrix acts to bond and protect the fibers and to provide for transfer of stress from fiber to fiber through shear stresses. Fibers can be in form of steel fibers, glass fibers, natural fibers, synthetic fibers, etc. The mechanism by which fibres produce resistance to freezing and thawing is that fibres introduction reduces water absorption of the concrete increasing penetration resistance to de-icing salts. Reduced water absorption is a function of the fibres to reduce plastic shrinkage cracking, reducing the ability of water to permeate into the bleed in a concrete. So this research paper describes experimental studies on the use of coconut fibre as enhancement of concrete.

Comparative Study of Mechanical Properties of Self - Healing Concrete Using I...IJERA Editor
Cracks in concrete are the main reason for a decreased service life of concrete structures. It is therefore more
advisable and economical to restrict the development of early age small cracks the moment they appear, than to
repair them after they have developed to large cracks. A promising way is to pre-add healing agents (Methyl
methacrylate) to the concrete to heal early age cracks when they appear, i.e. the so-called self-healing approach.
By this approach, Methyl methacrylate was used as self – healing agent and its self-healing capability was
confirmed by UPV test. In that self – healing concrete, Industrial Waste Steel Scrap and Polyethylene fiber were
added to evaluate its mechanical properties. The experimental results shown that the self – healing concrete
can yield high compressive strength when Polyethylene fiber was added and also yield high tensile strength by
adding Industrial waste steel scrap. Also, it is found to be economical by adding steel scrap in self – healing
concrete instead of steel fiber.
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.
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.
