This study investigated using graphene oxide (GO) to improve the mechanical properties of concrete. GO was added at concentrations of 1% and 2% by weight of cement to concrete mixes. Specimens of both concrete cubes and cylinders were cast and tested after 28, 56, and 90 days of curing. The concrete containing GO showed improved compressive and split tensile strengths compared to normal concrete without GO. The study demonstrated the feasibility of using GO to enhance the mechanical properties of concrete.
In this experimental study, the reinforcing effects of graphene oxide (GO) on portland cement paste are investigated. It is dis- covered that the introduction of 0.05% by weight GO sheets into the cement paste can increase the compressive strength and tensile strength Of the cement composite due to the reduction of the pore structure of the cement paste.The inclusion of the GO Sheets enhances the degree of hydration of the cement paste. However, the workability of the GO-cement composite becomes somewhat Reduced. The overall results indicate that GO reinforcing the engineering properties of portland cement.

As concrete is the most abundant material used in the world, it contains aggregate content of around 60 to 70 %. Since aggregate are being used rapidly there has been a scarcity in the avaibility of these materials. This research investigates the effect of partially replacing aggregates by burnt brick bats and lateritic fines in concrete respectively for M25 grade concrete. The incorporation is done for 5%, 10% and 15% of burnt brick bats for coarse aggregate and by talking 15% of lateritic fines as constant for fine aggregate by conducting compressive strength test which gave the optimum value of 15% for natural sand. The compressive strength, split tensile strength and flexural strength was conducted. The results showed density of of the concrete incorporating brick and laterite was lower compared to conventional concrete, the concrete with 5% burnt brick and 15% lateritic soil showed increased strength for 7 days compared to normal concrete but when 28 days test was conducted the strength was similar to conventional concrete. The split tensile and flexural strength of replaced concrete was found to be lower than the nominal concrete.
The Coupled Effect of Nano Silica and Superplasticizer on Concrete Fresh and ...IJMER
The The effect of individual and combined additions of both nano silica (NS) and
polycarboxylate-ether superplasticizer (SP) admixtures on concrete mixes were studied. Twenty concrete
mixes were prepared, keeping the water/cement ratio constant at w/c = 0.40, with different amounts of
SP admixture, and NS. the superplasticizer was studied in the range of (0 – 0.88)% (over cement weight),
nano silica additions were tested at (0 – 3.00)% range (over cement weight). Early, and late
compressive strengths, as well as results of fresh concrete (slump) test of formulations were evaluated by
means of design of experiments, in order to identify the primary factors and their interactions on the
measured properties. The most desirable NS and SP % were determined. The results showed that
regardless of the used NS percentage, the higher compressive strength results were reached at, or
around SP observed saturation dosage (0.66% by weight cement). The statistical approach applied here
enabled to develop relations, which could adequately describe the dependency of both the compressive
strength, and slump on the composition of NS, and SP concretes. These relations were presented as
contour plots, which from a practical point of view could serve as a basis for mix design
Due to increase in construction activities there is increase in demand for concrete, which leads to over use of natural resource. Hints, conservation of natural resource is necessary thing. Among the waste generated it is presumed that 10% to 15% of waste hazardous and increasing at the rate of 2% to5% per year resulting in environmental pollution and effect to living beings. These wastes can be utilized as alternative construction material, so that would be one of the consistent ways of disposal. This paper attempts to study the strength parameters such as compressive and tensile strength of paper sludge ash (15% and 20%) as partial replacement of cement, M-sand (50% and 60%) of partial replacement of fine aggregate for a design mix of M25.

Effect of Partial Replacement of Sand by Mild Steel Filings in Concreteijtsrd
Metals waste materials create serious environmental problems, mainly owing to the inconsistency of the waste streams. Mild steel filings are very small pieces of steel that look like a steel fiber. They are very often used in science demonstrations to show the direction of a magnetic field. The purpose of this project is to evaluate the possibility of using mild steel filings as one of the components of concrete mix. Five different percentage of mild steel filing were added to concrete mix to measure the variation which may be obtained in compression and tensile strength of concrete after 7 & 28 days. A number of standard cubes and cylinders were casted and tested in this study using 0% (control), 10%,15%, 20% and 25% of mild steel filing in concrete mix. Concrete cubes of size 150mm x150mm x 150mm and cylinders will be prepared and tested for compressive strength and tensile strength respectively after 7 and 28 days. A result data obtained has been analyzed and compared with a control specimen. Result data clearly shows percentage increase in 7 and 28 days compressive strength and flexural strength.

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.

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.

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.
