This cover story, featured in the May 2017 issue of Hard Hat News, explains how PKF-Mark IIII took a break from traditional pile driving methods to rent two RTG Pile Driving Rigs from Equipment Corporation of America for its PA Turnpike/I-95 Interchange Project in Bucks County, Pa. The switch paid off.
This story, featured in GeoDrilling International, explains how a forward-thinking contractor broke with tradition to install bridge foundations on the PA Turnpike/I-95 Connector Project in Pennsylvania. PKF Mark III historically relied on a crane-suspended pile hammer. Its decision to rent RTG pile driving rigs from Equipment Corporation of America (ECA) is paying off with doubled productivity, reduced labor, increased safety, and cost-savings.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

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!

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.
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.

“Given his experience with th e previou s m ach in e (RG 19T) it on ly took h im a
cou ple of days to get acclim ated,” Keou gh recalls, adding th at ECA’s su pport
was key. “He felt com fortable having a ph on e n u m ber h e cou ld call an d get all

Th e RM 20 gave PKF th e ability to dou ble produ ction , bu t th e on u s wa s on its

rig’s h yper efficien cy, du bbed th is process “feedin g th e beast.”
It requ ired both ph ysica l an d m en tal effort for PKF’s crew. While th e piles ar -
rive on site marked with drivin g depth s, th ey do n ot always m atch the su pplied
borin gs. It requ ires th e team to ch oose an d m an age piles based on h ow th e
oth ers are goin g in to avoid waste.
PKF was accu stom ed to being able to revisit driven piles before splicin g be-
cau se the h am m er with leader dan gles overh ead an d can be reposition ed. Usin g
a track-m ou n ted m ach in e like th e RTG requ ired carefu l selection of pile sizes
an d im m ediate splicing in areas where driven piles were clu stered several rows
deep. PKF rose to th e ch allen ge a s eviden ced by th e crew’s produ ction rate of
u p to 20 piles in stalled per day.
Th e RM 20’s produ ctivity dazzled PKF regardless of wh eth er th e piles were
plu m b or battered. Th e RM 20 can effectively drive battered piles becau se of its
adju stable leader, wh ich can tilt backwards 45 degrees, an d forward an d side-
ways 18.5 degrees. Th e h igh tu rn in g poin t of th e m ast provides stability in even

ver on the jobsite proved essential.
“Th e RM 20 is perfect for th is project becau se you have h igh m obility in a con -
fin ed area,” explain s Sales Director North Am erica Dirk Him borg of Ram m tech -
n ik, Gm bH. “Th e rig h as th e option to be fitted with a h ydrau lically-driven m ast

The RM 20 can effectively drive battered piles because of its adjustable lead-
er, which can tilt backwards 45 degrees, and forward and sideways 18.5 degr

PKF-Mark had historically relied on a crane-suspended pile hammer. It’s decision
to rent pile driving rigs from ECA is paying off with doubled productivity, reduced
labor, increased safety, and cost-savings.

Th e added power of th e RM 20 with
HRS 5 facilitated com plian ce with an
a ggres s ive Pen n DOT s pecifica tion ,
wh ich requ ires 20 blows per inch to re-
fu sal on bedrock. PKF was pen etratin g
a silty s an d su rface, u nderlain by a
tougher layer of saprolite, which varied
in depth. PKF drove 14 x 89 H-piles to
dense bedrock at 12 to 80 feet, althou gh
35 feet was th e average. Piles were
capped with a h eavy-du ty steel tip for
added pen etration.

PKF was driving piles with ham m ers
and leads from 7 a.m . to 10 p.m . De-
spite its respect for local n oise ordi-

“Wh en we switch ed to th e RM 20
th ere were n o com plaints even thou gh
we were closer to th e neigh borh ood,” h e
recalls. “You can stan d 30-feet away

“There is a n oise percu s sion system

Keou gh says. “Th e on e th in g th at we

its heavy/ highway con stru ction proj-

New J ersey, and North ern Delaware —
will n ow provide th is work as su bcon -

on th e PA Tu rn pike/ I-95 In terchange

will inclu de RTG Pile Drivin g Rigs.
The RM 20 offered a level of confined space functionality and the ability to navigate chal-
lenging terrain, which would not have been possible with the traditional crane-suspended vi-
bratory hammer with leaders.
