5G and AI/ML use cases are revolutionizing industries by enabling faster data processing and decision-making.

• 5G enabling real-time data transmission for AI/ML algorithms

• AI/ML optimizing network performance and resource allocation in 5G networks

• AI-powered predictive maintenance for 5G infrastructure

• AI-driven personalized content delivery over 5G networks

• AI/ML enhancing cybersecurity measures in 5G networks

Use XOR operation to swap two variables without using a temporary variable

• Use XOR operation to swap two variables without using a temporary variable

• Example: a = 5, b = 10. a = a XOR b, b = a XOR b, a = a XOR b. Now a = 10, b = 5

Matrix multiplication in CUDA involves parallelizing the computation across multiple threads on the GPU.

• Use CUDA kernels to launch parallel threads for matrix multiplication.

• Divide the matrices into blocks and load them into shared memory for faster access.

• Implement the matrix multiplication algorithm in CUDA C/C++.

• Ensure proper memory management and synchronization between threads.

Merge two sorted arrays into a single sorted array

• Create a new array to store the merged result

• Iterate through both arrays simultaneously and compare elements

• Add the smaller element to the new array and move to the next element in that array

• Continue until all elements from both arrays are merged

Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

• Transformers have two coils of wire, known as primary and secondary coils, which are magnetically coupled.

• When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.

• The ratio of the number of turns in the primary an...read more

To replace a blown 22 kv line fuse, safety measures include de-energizing the line, using proper PPE, and following proper procedures.

• De-energize the line before attempting to replace the fuse

• Use insulated tools to avoid electrical shock

• Wear appropriate PPE such as rubber gloves, safety glasses, and flame-resistant clothing

• Follow proper lockout/tagout procedures to ensure the line remains de-energized during the replac...read more
