Explain the following static channel allocations mechanisms: i) TDMA ii) FDMA

Static Channel Allocation: TDMA and FDMA Explained

Time Division Multiple Access (TDMA)

  • Divides time into slots.
  • Each slot assigned to a user.
  • Users transmit only during their assigned slot.
  • Improves efficiency compared to FDMA in some scenarios.
  • Prone to synchronization issues.
  • Vulnerable to burst errors.

Frequency Division Multiple Access (FDMA)

  • Divides the available bandwidth into frequency channels.
  • Each user assigned a separate channel.
  • Simultaneous transmission possible on different channels.
  • Simple implementation.
  • Less efficient use of bandwidth compared to TDMA in some cases.
  • Guard bands needed to prevent interference.

Discuss basics of the motion field of rigid objects with necessary equations.

Understanding Rigid Object Motion in Computer Vision Defining the Motion Field The motion field describes the apparent movement of pixels in an image sequence. It's a 2D vector field, where each vector represents the velocity of a corresponding pixel. For rigid objects, all points move coherently, unlike non-rigid objects with independent movements. Motion of a Rigid Object: Translation Pure translation involves only a change in position. Let `(x, y)` be the pixel coordinates and `(u, v)` be the displacement vector. Then, `u = t_x` and `v = t_y`, where `t_x` and `t_y` are the components of the translation vector. Motion of a Rigid Object: Rotation Pure rotation around a point (e.g., the object's center) is described using a rotation matrix. The rotation matrix R is a 2x2 matrix dependent on the rotation angle θ. The rotation equations are: `x' = x cosθ - y sinθ` and `y' = x sinθ + y cosθ`. `x', y'` are the rotated coordinates. Combi...

Explain different classes of attacks

Demystifying Cyber Attacks: A Classification for Enhanced Security Passive Attacks Eavesdropping on network traffic. Traffic analysis to infer communication patterns. Monitoring user activity without interaction. Active Attacks Modification of data in transit. Denial-of-service attacks flooding systems. Impersonation through forged packets. Man-in-the-middle attacks intercepting communication. Attacks Based on Target Web Application Attacks (SQL Injection, XSS). Network Attacks (ARP Spoofing, DDoS). Host-Based Attacks (Malware infections, privilege escalation). Data Attacks (Data breaches, data exfiltration). Attacks Based on Methodology Exploiting vulnerabilities in software/hardware. Social engineering (phishing, baiting). Brute-force attacks (password guessing). Insider threats (malicious employees). Attacks Based on Intent Data theft for financial gain or espionage. System disruption for vandalism or protest. Data manipulation to defraud or manipulate....

What is meant by “Scope” and “Rigor” of a project? Briefly discuss the factors that influence Rigor during agile project development.

Agile Development & UI/UX: Balancing Scope and Rigor What is Project Scope? Defines the project's boundaries. Includes features, functionalities, and deliverables. Outlines what will be created and what will not. Crucial for managing expectations and resources. What is Project Rigor? The level of precision, formality, and adherence to process. Impacts quality, consistency, and predictability. Higher rigor often means more documentation and testing. Lower rigor allows for greater flexibility and speed. Factors Influencing Rigor in Agile Development Team Expertise: Experienced teams might need less formal processes. Project Complexity: Complex projects demand higher rigor. Client Involvement: High client involvement may necessitate more defined processes. Regulatory Requirements: Compliance needs increase rigor. Risk Tolerance: Higher risk tolerance can lead to lower rigor. Time Constraints: Tight deadlines can impact the level of rigor. UI/UX Design Complexi...
