Network topologies Definition: Network topologies define how nodes (processors/computers) are interconnected in parallel and distributed systems. The choice of topology affects performance, scalability, and cost. Key Metrics: Degree: Number of links per node. (Formula: deg = connections per node) Example: In a linear array, each node (except ends) has 2 links. Diameter: Longest shortest path between any two nodes. (Formula: diam = max distance) Example: Linear array with 8 nodes has diameter 7 (P₀ to P₇). Bisection Width: Minimum links to cut to split the network into two halves. (Formula: bw = min cuts) Example: Binary tree has bw=1 (cutting the root disconnects it).4 1. Linear Array Define : Nodes are connected one after another in a straight line. Each node (except the ends) connects to two neighbors one on the left and one on the right. Explanation : Simple to build and easy to understand, but not efficient for large networks. Long distance between farthest nodes makes comm...

Asymmetric-key algorithms are algorithms used in cryptography that use two different keys  a public key for encryption and a private key for decryption. These keys are mathematically related, but the private key cannot be easily derived from the public key. Types: RSA (Rivest–Shamir–Adleman): It uses large prime numbers to generate the key pair and supports both encryption and digital signatures DSA (Digital Signature Algorithm): DSA is primarily used for creating digital signatures, ensuring the authenticity. Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext  Types: Stream Cipher:  Stream Cipher Converts the plain text into cipher text by taking 1 byte of plain text at a time. Block cipher: Converts the plain text into cipher text by taking plain text's block at a time DES? DES stands for Data Encryption Standard . It is a symmetric-key algorithm used to enc...

Ai Mental Health & Cyber Safety Presentation

Module A - The Normalization Engine Linguistic Challenge: Roman Urdu lacks standardized orthography (e.g., "kesa" vs "kaisa"), creating orthographic "noise" that significantly degrades the accuracy of downstream AI models. Technical Role: Acts as a Sequence-to-Sequence (Seq2Seq) transliteration and lexical normalization layer to standardize inputs before analysis. Model: A specialized transformer architecture, specifically m2m100 fine-tuned on parallel corpora or UrduParaphraseBERT. Primary Dataset: Roman-Urdu-Parl (RUP). A large-scale parallel corpus of 6.37 million sentence pairs designed to support machine transliteration and word embedding training. Link: https://arxiv.org/abs/2503.21530 Outcome: Reduces orthographic noise by achieving up to 97.44% Char-BLEU accuracy for Roman-Urdu to Urdu conversion, ensuring Module B receives high-quality "clean" data for risk analysis. Module B - Risk Stratification (BERT) Heading: The "Safety ...
