1) SCC is constructing a 15,000 seat stadium for Jamestown Community College with a deadline of August 26th, 2017 and a projected net income of $450,000.
2) Analysis of alternatives found expediting the pouring of the seat gallery supports (Task H) decreased the project duration and increased net income the most.
3) The recommendation is for SCC to expedite Task H, cutting the duration from 10 to 6 weeks and incurring the $22,000 charge, as it provided the best outcome with the highest probability of facing a strike or harsh winter during construction.
Beyond B2B Consumerization: How Instant Commerce™ in B2B Changes the Future o...SAP Ariba
So what’s the next big thing in B2B e-commerce? Participate in this session to learn how B2B e-commerce is going beyond consumerization to instant commerce. We will examine: what factors will lead to B2B sector consolidation; who benefits when demand chains meet supply chains; what is driving the new Era of Instant Commerce™; and which new business models will profit from this new era.
City Planning Retrospective of Joseph A. Colón.ppsxJoseph A. Colón
After meeting his then-future boss, Leslie T. Alley, at a Public Safety Improvements Community Forum in the French Quarter in March 2017, Joseph A. Colón had the privilege to be recruited into the City Planning Commission (CPC) of New Orleans in July 2017.
Quickly learning the responsibilities of the base work tasks, he was soon nominated to contribute to studies, special assignments, committees, and handle significant cases in town.
This retrospective will not only exhibit how Joseph promoted the health, safety, & welfare of the citizens of New Orleans, but how his time at the CPC changed him.

Case Description
The City of Toronto has progressed on so many fronts since the October 2019 municipal election
saw a liberal-minded mayor elected to office. The dark, backward days of former Mayor Bobby
Bored and his conservative, hawkish brother are a distant memory.
In addition to new public transit plans, the city moved quickly to initiate a project to replace its
professional baseball stadium. The current stadium, built in the late 1980s is outdated and
generally recognized as the worst professional stadium in North America.
The G&E Company is preparing a bid to build the new 74,000 seat Avignon Stadium (named
after a beautiful town in southern France). The construction must start June 1 2020, and be
completed in time for the start of the 2024 season. A penalty clause of $100,000 per day of delay
beyond April 20, 2024, is written into the contract.
Ben Keith, the president of the company, expressed optimism at obtaining the contract and
revealed that the company could net as much as $5 million on the project. He also said if they are
successful, the prospects for future projects are quite good since there is a projected renaissance
in building classic baseball parks with modern luxury boxes.

The baseball stadium is an outdoor structure with a retractable roof. The project begins with
clearing the site (activity 2). Once the site is clear, work can start simultaneously on the structure
itself and demolishing an adjacent building site (activity 3). This demolition is necessary to
create a construction stage for storing materials and equipment (activity 4).
The work on the stadium begins by driving 160 support pilings (activity
5). Next comes the pouring of the lower concrete bowl (activity 6). Once this is done and the
construction site has been set up, then the pouring of the main concourse (activity 7)), the
installation of the playing field (activity 8), and the construction of the upper steel bowl can
occur (activity 9).
Once the concourse and upper bowl are completed, work can start simultaneously on building

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

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.
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.
