This study investigated the compressive strength of pervious concrete with varying substitutions of recycled coarse
aggregates. Testing found that pervious concrete with 30% recycled coarse aggregates had the highest compressive strength.
A probabilistic analysis using Monte Carlo simulation determined that the compressive strengths followed a normal
distribution. The analysis estimated the ranges of compressive strengths for different recycled aggregate substitutions to be
between 5.8-7.3 MPa at 5%, 8.2-10.5 MPa at 15%, 8.4-10.8 MPa at 25%, 11.5-14.8 MPa at 30%, 9.6-12.8 MPa at 35%, and 8.6-

Studies on reinforced hollow concrete block masonryeSAT Journals
Abstract Masonry may be defined as the assemblage of building units joined with the help of cementitious material or any accepted joining material to perform required function. It has its own reputation and performs multi-functions in load bearing structures such as- supporting loads, dividing spaces, thermal and acoustic insulation, weather and fire protection etc, but it has to be provided separately in framed structures. In present scenario, there is a great demand for construction of Multi-storied residential buildings in urban area because of needful requirements. Most of such buildings are constructed using RC-framed structure. On the other hand RC-framed structures are expensive and relatively difficult to construct because of the need for formwork. Masonry has a great benefit since it does not need form work. If moderate to High strength Engineered hollow concrete blocks are available, one can think of providing reinforcement through the core of such Hollow blocks. In this project an attempt has been made to obtain the load carrying capacity of Reinforced Hollow Concrete Block Masonry through experimental investigation by considering two different percentages of steels - for this totally four number of Reinforced hollow concrete block masonry prisms (RHCBM) using 12 mm diameter bar and six number of Reinforced hollow concrete block masonry prisms (RHCBM) using 8 mm diameter bar were casted and tested. Further, an attempt has been made to compare the experimental load carrying capacity with the conventional mechanics based approach used for analyzing short columns. There was a fairly good co-relation between the analysis and experiments. Key Words: Unreinforced Masonry, Reinforced Hollow Concrete Block Masonry.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
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.

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.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
