The document presents the results of an experimental study that tested reinforced concrete (RCC) beams strengthened with different materials to increase their flexural strength. 12 RCC beams were prepared and tested under flexure. Some beams were wrapped with waste PVC flex banners, some were wrapped with chicken mesh and flex banners, and some were wrapped with weld mesh and flex banners. The materials were bonded to the beams using different adhesives. It was found that beams wrapped with just flex banners saw a 6% increase in load capacity. Beams with chicken mesh and flex banners saw a 21% increase. Beams with weld mesh and flex banners saw the greatest increase of 147%. The study showed that commonly available waste materials can significantly

Experimental Behavior of RC Beams Strengthened by Externally Bonded CFRP with...IJERDJOURNAL
Abstract:- Carbon fiber-reinforced polymers (CFRP) laminates, or plates, offer very high-strength potential; however, handling of long pieces of these flexible plates can present challenges under field conditions. The development of methods for splicing CFRP plates will enhance the versatility and Practicality of using these materials in field applications. This paper studies the efficiency of CFRP lap splice in externally bonded CFRP flexural strengthened reinforced concrete beams. Seven half-scale beams with different conditions were tested in two-point bending until failure. Two groups were tested; the first one includes control specimens: the first without CFRP strengthening, the second strengthened with full length and without splice, and the third with cutoff at middle of the beam. All specimens in the second group having cut-off at the middle and with lap splice lengths equal 300, 450, 600, 900 mm. respectively on each side of the cut-off. The study illustrates the effect of confinement on the first crack load, failure load, mid-span deflection, and strain in both reinforcement and CFRP. The failure load was also predicted analytically by CEB-FIP (1993), adopting the traditional sectional analysis for strain compatibility. Instead of strain measuring, three accurate bond-slip models are used to provide accurate prediction for the contribution of CFRP in the flexural capacity of the strengthened beam since all strengthened beams are failed by interfacial debonding of CFRP.
Strengthening structures via external bonding of advanced fibre reinforced polymer (FRP)
composite is becoming very popular worldwide during the past decade because it provides a more
economical and technically superior alternative to the traditional techniques in many situations as it
offers high strength, low weight, corrosion resistance, high fatigue resistance, easy and rapid
installation and minimal change in structural geometry. Although many in-situ RC beams are
continuous in construction, there has been very limited research work in the area of FRP
strengthening of continuous beams. In the present study an experimental investigation is
carried out to study the behavior of continuous RC beams under static loading. The beams are
strengthened with externally bonded glass fibre reinforced polymer (GFRP) sheets. Different scheme
of strengthening have been employed. The program consists of fourteen continuous (two-span) beams
with overall dimensions equal to (150×200×2300) mm. The beams are grouped into two series
labeled S1 and S2 and each series have different percentage of steel reinforcement. One beam from
each series (S1 and S2) was not strengthened and was considered as a control beam, whereas all
other beams from both the series were strengthened in various patterns with externally bonded GFRP
sheets. The present study examines the responses of RC continuous beams, in terms of failure modes,
enhancement of load capacity and load deflection analysis. The results indicate that the flexural
strength of RC beams can be significantly increased by gluing GFRP sheets to the tension face. In
addition, the epoxy bonded sheets improved the cracking behaviour of the beams by delaying the
formation of visible cracks and reducing crack widths at higher load levels. The experimental results
were validated by using finite element method
Experimental Investigation of Axial Capacity and Energy Absorption of SFRC Co...IJMERJOURNAL
ABSTRACT: This paper presents the results of the experimental study on the axial compressive behavior of steel fiber reinforced concrete (SFRC) wrapped with fiber reinforced polymer (FRP). A total of 18 concrete cylinders were tested under axial compression. The effects of steel fiber parameters were investigated which includes fiber aspect ratio (AR) and fiber volume fraction (VF). The concrete cylinders were divided into groups of confined and unconfined ones. In accordance with previous study, it was found that, FRP confined cylinders showed greater axial stress than that of unconfined specimens. Although the presence of steel fiber increases the peak axial stresses for both confined and unconfined group of specimens, but no significant change of peak axial stress (and peak strain) has been observed in both confined and unconfined group due to increase of fiber volume ratio. But with the increase of fiber aspect ratio, the peak axial stresses of both unconfined and FRP-confined cylinders were found to slightly decrease. It was also observed that, concrete specimens reinforced with internal steel fiber absorbed much higher energy than that of unreinforced ones.

Glass fibre reinforced plastics (GFRP) based on resin recovered from recycling plastic waste has been shown to possess mechanical properties satisfying normative requirements. This paper investigates the flexural behavior of concrete beams reinforced with GFRP produced from resin recovered from recycled plastic wastes. A total of fifteen of beams of sizes 150 ×150 ×900mm and 100 × 100 × 500mm reinforced with GFRP made from recycled glass fibre reinforced polymer was tested. The flexural test results yielded lower ultimate load, lower stiffness and larger deflections at the same load when compared with the control steel reinforced beam. However, the ultimate flexural strength of beams, reinforced with GFRP from recycled resin was at least four times higher than that of the control unreinforced beam. This is in agreement, quantitatively and qualitatively, with the trend of these parameters in GFRP reinforced concrete based on virgin resins. The results therefore confirm the applicability for structural uses with the accompanying benefits of wealth creation, value addition and environmental sustainability.

Fiber-reinforced polymer (FRP) application is a very effective way to repair and strengthen structures that have
become structurally weak over their life span. FRP repair systems provide an economically viable alternative to traditional
repair systems and materials. In this study, an experimental investigation on the flexural behavior of RC T-beams
strengthened using glass fiber reinforced polymer (GFRP) sheets are carried out.
Reinforced concrete T beams externally bonded with GFRP sheets were tested to failure using a symmetrical two
point static loading system. Seven RC T-beams were casted for this experimental test. All of them were weak in flexure and
were having same reinforcement detailing. One beam was used as a control beam and six beams were strengthened using
different configurations of glass fiber reinforced polymer (GFRP) sheets. Experimental data on load, deflection and failure
modes of each of the beams were obtained. The effect of different amount and configuration of GFRP on ultimate load
carrying capacity and failure mode of the beams were investigated.
The experimental results show that externally bonded GFRP can increase the flexural capacity of the beam
significantly. In addition, the results indicated that the most effective configuration was the U-wrap GFRP.A series of
comparative studies on deflection between the present experimental data and results from finite element method and IS code
method were made. A future area of research are being outlined.

Shear Behavior of Steel I-Beams Strengthened With CFRP StripsINFOGAIN PUBLICATION
This paper studies the behavior of simply supported steel I-beams strengthened with carbon fiber reinforced polymers (CFRP) strips on the web as shear reinforcement. The experimental program contains seven simply supported steel beams. One of them was considered as a control beam and the other specimens were strengthened with different schemes; varying the position of CFRP strips to the web, its number of layers and its angle of orientation. The results show that applying CFRP strips on the web of the steel I-beams was an effective strengthening method for increasing the load bearing capacity and decreasing the deformations. Using two layers of diagonal CFRP strips on both sides of the web realized the highest increasing in the load capacity. Moreover, finite element analysis method has been utilized to analyze the tested specimens using ANSYS. A great convergence between the experimental results and the corresponding ones obtained from finite element simulation.

Behaviour of Glass Fiber Reinforced Polymer Composite in Flexure Shear Streng...ijtsrd
The corrosion of steel reinforcement in concrete reduces the life of structures, causes high repair costs and can endanger the structural integrity of the structure itself. Glass fibre reinforced polymer GFRP offers a number of advantages over steel especially when used in marine and other salt laden environments. GFRP reinforcing bars are gradually finding wider acceptance as a replacement for conventional steel reinforcement as it offers a number of advantages. Technical studies on a number of concrete structures, from five to eight years old and constructed with GFRP reinforcement, have shown that there is no degradation of the GFRP from the alkaline environment. Concrete is very strong in compression but it is extremely weak in tension. To resist the tensile stress, steel reinforcement is provided in concrete. Reinforcement corrosion and structural deterioration in reinforced concrete structures are common, and prompted many researchers to seek alternative materials and rehabilitation techniques. One such material that has been offered as an alternative to mild steel reinforcement is Glass Fibre Reinforced Polymer GFRP bars and flats. For the repair and strengthening of structural concrete members, strengthening with Glass Fibre Reinforced Polymer GFRP plates is an excellent option. The present work is to study the behavior of Shear resistance of the silica coated GFRP stirrups in the shear test zone. A series of studies were conducted using silica coated GFRP stirrups in shear zone. It is observed that beams with silica coated GFRP flats shear reinforcement have shown failure at higher loads than the theoretical failure loads. Further it is observed that GFRP flats as shear reinforcement exhibit fairly good ductility. Er.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. 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.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
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.
