Key Competition Performance Metrics
CyberGuard RT-IDS
Problem Statement & Dual-Path Scoring
Signature-based IDS fails against novel zero-days, while pure machine learning generates unacceptable false-positive lockouts. CyberGuard solves this with a decoupled dual-path ML pipeline: a PyTorch Deep Autoencoder measures continuous reconstruction loss to score unknown anomalies, while a parallel XGBoost classifier categorizes 14 distinct attack classes (DoS, PortScans, Infiltration).
Guarded Containment & Durable Rollback
Automated responses mutate host firewall rules (Windows netsh or Linux iptables) only through cryptographically signed receipts stored in a SQLite WAL database. An asynchronous background reaper enforces strict Time-To-Live (TTL) expiration: rules automatically expire unless explicitly renewed, preventing permanent network partition errors.
Mecha-Bot Monorepo
Asynchronous Ingress & State Isolation
Engineered using Python 3.12, aiogram 3.x, and Asyncio, the platform resolves high concurrent load bottlenecks through a multi-tier pipeline. Incoming updates pass through custom rate-limiting middleware (token bucket algorithm), decoupling fast network ingress from database operations to sustain over 2,400 requests/minute without process freeze.
Academic Services & 582 Automated Tests
Powers Mechatronics departmental workflows: automated lecture schedule alerts, syllabus distribution, and Arabic full-text search with BM25 indexing. The monorepo enforces rigorous reliability with 582 unit and integration tests executed automatically via GitHub Actions CI across all pull requests.
ARIA NEXUS Edge AI
100% Offline Multi-Stage Voice Pipeline
Engineered for air-gapped robotics laboratories where cloud connectivity is prohibited or unstable. Uses Silero VAD for sub-50ms acoustic boundary detection, streaming directly to quantized Faster-Whisper INT8 speech recognition, local Qwen 2.5 7B reasoning via Ollama, and Kokoro neural TTS for natural Arabic/English speech synthesis.
Ministerial Distinction & Team Collaboration
Developed within Team Zenith (جامعة البصرة), Sajad directed the audio streaming buffers, thread-safe queue dispatching, and hardware monitoring telemetry. Demonstrated live before the Ministerial Judging Committee at NURAI 2026, earning a Ministerial "Good" Evaluation under Certificate #11143e3985089de9116ff664.
Player (Lyrune)
Low-Allocation PCM DSP & Parametric EQ
Engineered in Kotlin 2.0 and Jetpack Compose around direct, low-level PCM audio buffer manipulation. By extending AndroidX Media3 BaseAudioProcessor, Player eliminates platform wrapper lag, routing 16-bit / 32-bit float audio frames through Biquad parametric filters, stereo matrix crossfeed, and safe dynamics peak limiting without runtime garbage-collection pauses.
Lock-Free PCM Tap & 2048-Pt Hann FFT
To ensure visualizer integrity, an atomic ring-buffer PCM tap decouples real-time audio playback from the rendering pipeline. An off-UI-thread analyzer executes a 2048-point Hann-windowed Fast Fourier Transform, delivering 64 logarithmic frequency bands interpolated smoothly at 60–120 FPS in Jetpack Compose with zero audio dropouts.
Mechatronics Hardware Lab
8086 Register-Level Firmware & Interrupts
Direct academic implementation of 16-bit 8086 microprocessor assembly. Demonstrates explicit register operations (AX, BX, CX, DX, SI, DI), memory segmentation, stack frame allocation, and hardware interrupt service routines (INT 21h DOS syscalls, INT 10h video) governing low-level industrial process sequences.
LTspice SPICE Transient Modeling & Actuators
Numerical circuit simulations in LTspice XVII verifying power MOSFET switching transients, inductive flyback snubber damping, and op-amp signal conditioning. Interfaced with physical Arduino hardware rigs controlling HC-SR04 ultrasonic rangefinders and PWM servo actuators.
