Dragline machine at dhudhichua project ,singrauliTauhid Mohammad
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining.
Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site.
During its forward movement, the blade cuts the ground and the loosened earth collected in the body of scraper. When the scraper is fully loaded, it is raised above ground d taken to the site of dumping. The earth from the scarper is than taken out by opening the bottom of it and the earth is laid in layer of required thickness.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.

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.
2. Dragline
The basic character of the machine is dragging the bucket
against the material to be dug.
A dragline is used to excavate the earth and load it into
hauling units such as trucks or tractor pulled wagons or to
deposit it into dams/ embankments or spoil banks near the pit
from which it is excavated.
Primarily, the function of a dragline are as that of a power
shovel but in some projects, a dragline has distinct advantages
compared with power shovel because of its long light boom.
3. Procedure of Dragline
Excavation is started by swinging the empty bucket to the
digging position, at the same time slacking off drag and hoist
cables.
Then the bucket is pulled towards the machine while digging
depth is regulated by means of the tension maintained in the
hoist cable.
When the bucket is filled, the operator takes in on the hoist
line while playing out the drag cable.
Hoisting, Swinging and Dumping of the loaded bucket follow
in that order, then the cycle is repeated.
4. Types of dragline and Particulars of
components
Crawler mounted dragline
Wheel mounted dragline
Truck mounted dragline
Particulars of components Range
Boom length 15m to 24m
Capacity in Kg 5400 to 2700
Boom angle in degree 20 to 45
Dumping radius in meter 12 to 26
Dumping height in meter 3 to 13
Maximum digging depth in
meter
12 to 6
Bucket quantity 0.38 m^3 to 3.25 m^3
5. Application of dragline
Bulk pit excavation.
Digging canal or a Ditch or near a pit.
Excavation in mines.
Road excavation.
Underwater excavation.
Useful in soft and medium hard soil.
6. Advantages of dragline
A dragline usually does not have to go into a pit or hole
for excavating the earth. It may operate on natural firm
ground.
When the excavated earth is to be deposited on nearby
banks or dams, then dragline is enough to dispose of
earth in one operation.
A dragline is excellent for excavating trenches without
shoring.
• Its output is lower than power shovel.
Disadvantages of dragline
