This document provides an overview of dimension stone and its uses in construction applications dating back to 6000 BC. Key points discussed include:
- Dimension stone has been used extensively for foundations, bridges, aqueducts, and military fortifications.
- Notable examples of dimension stone construction include buildings at Machu Picchu and structures along the Apennine highway in Italy.
- Granite and other low porosity crystalline rocks are desirable for their durability, though they are harder to excavate.
- Methods like the Rock Quality Designation (RQD) and Rock Mass Rating (RMR) systems were introduced to evaluate rock quality based on measurements of rock cores.

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.

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.

Our project explains about the student management. This project mainly explains the various actions related to student details. This project shows some ease in adding, editing and deleting the student details. It also provides a less time consuming process for viewing, adding, editing and deleting the marks of the students.
3. Dimension Stone
• Quarried dimension
stone has been
used as a building
material dating to
6000 BC in Jericho
• Used extensively
for foundations,
bridges, aqueducts,
road surfacing, and
military
fortifications
4. One of the most common applications of dimension stone has been
construction of gravity retaining walls, usually in mountainous areas
with steep bedrock slopes.
Machu Picchu, in Peru
Apennine highway in Italy Tioga Pass near Yosemite
5. • Nimrod’s Castle
was built by
European
Crusaders in the
12th Century using
basalt blocks and
limestone
• Earthen mounds
were often built
over tels, or rubble
piles, from
previous cities or
citadels, to gain
elevation
advantage for
defense
6. • Low porosity
crystalline rock,
such as granite,
has always been
desirable because
of its superior
durability
• Massive rocks
tend to be less
intensely jointed
or weathered, but
also
• Harder to
excavate
7. • Cyclopean masonry rock retaining wall supporting a
highway in the Andes Mountains of Peru. Note tunnel
at middle right excavated in rock to convey river flow.
8. RQD
• Rock Quality Designation index, or RQD, was introduced by Don
Deere in 1963. It judges rock quality based solely on
measurements of recovered rock core (above left) in 10 foot
increments, based on percent recovery and percentage of the
pieces longer than 4 inches.
9. RQD
• RQD = Σ pieces > 4” long (100)
total length cored
• 100-90 Excellent
• 90-75 Good
• 75-50 Fair
• 50-25 Poor
• <25 Very poor
the reported RQD value varies along
the scan line of the recovered core
10. • The Rock Mass Rating (RMR) System, or Geomechanics
Classification, was introduced by Dick Bieniawski in
1972-73. It has been continually refined, base don case
studies of actual excavations.
11. • “Rock” is a subjective term. Karl Terzaghi
arbitrarily defined hard rock as any natural
material having qu > 4000 psi, which is same as
structural concrete.
12. • Even the hardest rocks are perturbed by
discontinuitities; such as these sheet joints,
which are essentially tensile fractures, which
form a never ending series of blocks.
