Shovel and dumper combination is a type of heavy equipment used in open cast mining operations. It is composed of two separate machines, a front-end loader (shovel) and a backhoe (dumper). The shovel is used to scoop ore, rock, or other materials out of the mine, while the dumper carries the load to a designated area for further processing. This combination of machines allows for faster and more efficient mining operations, as the shovel can quickly scoop up large quantities of material, while the dumper can move the load quickly and safely. The shovel and dumper combination is an indispensable asset for any open cast mine, allowing for fast, efficient, and safe extraction of materials.

Design optimization of excavator bucket using Finite Element MethodIjripublishers Ijri
An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations,
such as digging, ground leveling, carrying loads, dumping loads and straight traction. Normally backhoe excavators
are working under worst working conditions. Due to severe working conditions, excavator parts are subjected to
high loads and must work reliably under unpredictable working conditions. Thus, it is necessary for the designers to
provide not only an equipment of maximum reliability but also of minimum weight and cost, keeping design safe under
all loading conditions.

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.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.

4. Dragline Planning Process
1. It starts with Review of the recons of the previous strips considering the
below points.
• Dragline performance in the last strip – Prime, Rehandle, KPIs.
• Geological conditions – model variations with actual survey.
• Geological disturbances – faults, folds, intrusions, etc.
• Geotechnical structures – joint planes, highwall & lowwall stability,
failures, if any.
• Water management – low points, sump & pump locations.
• Drill and blast access.
• Coal access.
• Light vehicle access & cable access.
• Cable interactions.
• Dragline dig sequence.
• Spoil fit issues.
• Floor treatment – Ex. Floor blasting, Tuff push, etc
• Dragline entry and exit into the pit.
• Cast profiles.
5. Dragline Planning Process
2. Review the Geo-technical design parameters for highwall and lowwall for
angles and identify the potential areas of concerns. The general profile of
the dragline is as shown below.

6. Dragline Planning Process
2. Take the coal edge from the previous strip on floor of coal and offset it by 3m
and then normalise the line. If seam thick ness is more than 5m then reduce
the offset distance. As the seam thickness is 10m in this mine, so there is no
offset from the floor Coal edge. Hence normalise the coal edge line to get rid
of all the kinks in the line before projecting up to lowwall crest.

Project this line
Project this line with Lowwall batter angle to a certain RL initially, may be 100m
high from the current coal edge RL. Then create a triangle surface (call
LW_37Batter) with these two lines to generate the Lowwall batter profile,
which will be used later to create Lowwall Toe & Crest lines.

3. Project the highwall Toe to the current Topo with the highwall batter angle. The
highwall batter angle is recommended by the Geo-tech analysis with a minimum
factor of safety 1.2. In a highly faulted areas, it is recommended to have a softwall
batter of 45 degrees rather than a presplit wall with 65 or 70 degree batter. Do the
same for endwall.
4. As the dragline exposes to top of coal so create the highwall toe line on TOC
and also take the coal edge line of the previous strip on the lowwall side from the
actual survey. Create the contours of the top of coal within this polygon.

8. Dragline Planning Process
5. Offset the Coal edge line on TOC by 50m towards lowwall and create a triangle
using CE-TOC and offset line which will intersect with the lowwall batter profile
created earlier. The intersection of these two triangles will give you the lowwall toe
line.

6. To create the lowwall crest line, project the Highwall Toe line at 90 degrees
vertical to an height equal to maximum dig depth of the dragline which is 45m in
this case and offset it by 200m towards lowwall. Generate the triangle with these
two lines and create an intersection line between this triangle and lowwall batter
profile to give you the lowwall crest line.
10. Dragline Planning Process
7. Then the remaining portion of the design process is to create the spoil.
1. Offset the lowwall crest line by 10m towards lowwall (which is the lowwall berm width,
it is different for different mines as recommended by the geo-tech analysis) which is
the spoil toe line.
2. Project this line at Spoil batter angle (which is 37 degrees – natural angle of repose,
this is also given by Geo-tech) to the maximum dump height of the dragline which is
45m in this case which gives the spoil crest line.
3. Then offset this line by 10m towards lowwall to give you the flat top of spoil &
4. Project down at 37 degrees to the topo to complete the design.

Create the triangle file from the design and find out the prime and spoil volumes
for each block to do the spoil balance.
At this stage get the Geo-tech approval of the design before start working on
sections and 3d-dig for the sequence and schedule.

A = Prime = Topo – Design surface (find out for each block, this is in bcm)
B = Spoil = Design surface – Topo
(find out for each block, this is in lcm. Divide by swell to convert to bcm)
13. Spoil Balance
Fill the spoil balance sheet with Prime, Spoil room, Top of coal RLs, Seam dips,
Highwall, Lowwall batters, lowwall berm width, Spoil strike lengths, etc. Which
populates the spoil fit condition in each block. Then play with the Key, elevated
and double elevated bench elevations to make the spoil to fit. Sample sheet is
shown below.
Based on the bench
elevations decide the
sequence of digging and
ramp locations between the
benches. Think of the cable
and LV access all the time.
14. Range Diagrams
Based on the spoil balance sheet, cut the sections in each block for every 100m
to find out the approximate cast volumes, dozer push volumes, dragline prime
and rehandle volumes. As this is based on the 2D plane, it is difficult to predict
the rehandles in cases like rolling the bridges and crossing the central ramps,
etc.
15. Range Diagrams
Range diagrams can be done using different software like Vulcan, Minescape,
Drag sim, etc. A sample range diagram done using Minescape is shown below.
16. 3d-dig – Dig Pack & Schedule
1. Based on spoil balance and Range diagrams adjust the lowwall crest elevations for the
design and build the new spoil from this changed lowwall crest line.
2. Export the Pre dig DTM with Pre-strip removed, dragline design, Coal seam roof & floor
into DXF format and then import all of them into 3d-dig.
3. Create the approximate blast profile in 3d-dig from the sections and blast the material
with the historical swell factor of the area and then start digging using dragline with a
dig swell of 5%.
4. Follow the sequence discussed during the spoil balance step and finish the dig.
5. Export the volumes (lcm) from 3d-dig and convert them to bcm to make a schedule with
the given dragline KPIs. Supply the schedule to the medium term scheduler.

17. Wall Plan
1. Prepare a wall plan with all the information showing the plan, sections, volumes, check
list, dig sequence, faults, low spots, coal access and Sign-off. Make copies one for
machine, one for production and one for tech-services. Sample wall plan is given below.
18. Exporting the design into Titronics
1. Export the design into DXF under ACTIVE layer name.
2. Export the triangle file of the design into DXF with FINAL layer name.
3. Export other lines like block lines, text, chop line, misfires, sump location, etc into DXF
under STATIC layer name.
4. Create a long section line along highwall toe. The RL of this line should be at the lowest
RL of the design. Export this line into DXF with CENTRELINELONG layer name.
5. Create a cross section line in the centre of the design. The RL of the line should be
more than the maximum RL of the design, i.e. this line should be above the design
triangle. Export this line into DXF with CENTRELINECROSS layer name.
6. Open the Leica translator and open the ACTIVE dxf file first. Then overlay all other dxf
files on top of this. Don’t save it as dozer file, if you save it first as dozer file then all the
layers in Leica translator will be copied under one layer and if you create map file after
this then dragline doesn’t distinguish between the different layers. Hence, create a map
file first then create the dozer file.
7. When you create the map file the text becomes horizontal, which will be rectified by
editing the map file in notepad and replace the number besides “P” with the actual
angle read from the design software. The text in the map file will be saved in the last, so
edit for each text with correct text angle and then save.
8. Upload the file into IMS (Titronics) and check with the machine for both plan view and
section view.
19. Execution of the dig
1. Conduct the pre-dig meeting and discuss the plan with the operators to get
the inputs and sequence modifications.
2. Make pit tour on the first day of each crew start to explain the plan for the
week and any short term changes and sequence modifications and discuss
the alternate options to improve the performance.
3. Take lots of photos and create a diary to record all the events in the dig, which
will be useful for the next dig in the same location for better planning and
execution. Learn from the mistakes you made.
4. Involve the operators in the planning process for the next dig and plan for the
next dig while the current dig is under execution to make the plan more robust
and pool proof.
5. Communicate with the other team members about the progress and share the
experiences.
20. Things to monitor for dragline to follow
1. Do not rip into coal with dragline teeth.
2. Take assistance of dozer in cleaning the top of coal to minimise
the coal loss.
3. Do not over dig or under cut highwall outside the design limits.
4. Expose the coal edge and lowwall toe without forming the skew-
ramps at the base of the lowwall.
5. Always maintain the lowwall berm as per the design.
6. Follow the bench elevations as indicated in the dig pack.
7. Always maintain the LV access to dragline and away from it.
21. Reconciliation
1. After the dig is finished, prepare reconciliation sheet comparing the plan Vs
actuals listing
1. KPIs
2. Prime and Rehandle volumes.
3. Coal tonnes & losses.
4. Blasting data.
5. Geo-technical issues.
6. Water management issues.
7. Highwall and lowwall profiles.
8. Major delays.
2. Request drill and blast for the floor treatment, if required.
