To solve problems in robots and detect faults, various techniques can be used such as monitoring sensors, analyzing error logs, conducting regular maintenance, and implementing diagnostic algorithms.
Monitor sensors to detect any abnormal readings or malfunctions.
Analyze error logs generated by the robot to identify recurring issues or patterns.
Perform regular maintenance checks to ensure all components are functioning ...
The 3 basic elements of fire are fuel, heat, and oxygen.
Fuel: Any material that can burn, such as wood, paper, or gasoline.
Heat: The energy required to raise the temperature of the fuel to its ignition point.
Oxygen: The presence of oxygen in the air, which supports the combustion process.
Fire is a chemical reaction that produces heat, light, and flames.
Fire is a rapid oxidation process that releases energy in the form of heat and light.
It requires three elements to sustain: fuel, oxygen, and heat.
Fire can be classified into different types based on the fuel source, such as wood, gas, or electrical fires.
Examples of fire include a burning candle, a campfire, or a house fire.
Mass production involves producing large quantities of identical products, while batch production involves producing smaller quantities of customized products.
Mass production focuses on efficiency and high volume production.
Batch production allows for customization and flexibility.
Mass production typically uses assembly lines and standardized processes.
Batch production often requires more manual labor and specialized e...
I applied via Recruitment Consulltant and was interviewed in Mar 2023. There were 2 interview rounds.
There are two types of masts commonly used in the oil and gas industry: drilling masts and derrick masts.
Drilling masts are used for drilling operations and are typically taller and heavier than derrick masts.
Derrick masts are used for lifting and hoisting heavy equipment and materials during drilling and production processes.
Both types of masts are essential for the safe and efficient operation of oil and gas plants.
E...
Two types of substructure are box-on-box and high floor substructure.
Box-on-Box: number of boxes depends on required height for wellhead and Bop stack
High floor substructure: developed for higher Bop stacks and wellheads
Draw works are an essential component of oil and gas drilling rigs, responsible for hoisting and lowering the drill string and casing.
Draw works provide the mechanical power to raise and lower the drill string and casing.
They consist of a large drum or spool around which the drilling line is wound.
Draw works are typically powered by an electric or diesel engine, providing the necessary torque and speed for drilling ope
Slipping, cutting, and receiving are techniques used in wire rope operations in the oil and gas industry.
Slipping refers to the process of adjusting the length of a wire rope by removing or adding wire rope strands.
Cutting involves severing a wire rope to a desired length using specialized tools.
Receiving refers to the act of accepting or taking in a wire rope after it has been cut or slipped.
These techniques are commo...

Merge Sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.
Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
Find pairs of integers in a BST whose sum is equal to a given number.
Traverse the BST and store the values in a hash set.
For each node, check if (X - node.value) exists in the hash set.
If yes, add the pair (node.value, X - node.value) to the result.
Continue traversal until all nodes are processed.
Merge overlapping time intervals into mutually exclusive intervals.
Sort the intervals based on their start time.
Iterate through the intervals and merge overlapping intervals.
Output the mutually exclusive intervals.
Example: [(1,3), (2,6), (8,10), (15,18)] -> [(1,6), (8,10), (15,18)]
Different types of hashing and alternative for Linear Chaining
Different types of hashing include division, multiplication, and universal hashing
Alternative for Linear Chaining is Open Addressing
Open Addressing includes Linear Probing, Quadratic Probing, and Double Hashing
An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.
AVL tree is a binary search tree with additional balance factor for each node.
The balance factor is the difference between the heights of the left and right subtrees.
Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.
Rotations are performed ...
Find the minimum number of squares whose sum equals to a given number n.
Use dynamic programming to solve the problem efficiently.
Start with finding the square root of n and check if it is a perfect square.
If not, then try to find the minimum number of squares required for the remaining number.
Repeat the process until the remaining number becomes 0.
Return the minimum number of squares required for the given number n.
Insertion sort for a singly linked list.
Traverse the list and compare each node with the previous nodes
If the current node is smaller, swap it with the previous node
Repeat until the end of the list is reached
Time complexity is O(n^2)
