Construction System and Composition

The construction system is defined by arches that generate a second direction, with wooden beams on the ceiling made wider to provide support. Arches are positioned perpendicular to the Qibla, utilizing semicircular arches to support the structure alongside Corinthian capitals. The materials consist of grey and red bricks. Key components include:

• Beam-Wooden Roof Board
• Roof evacuation channel
• Plaster false edges vault
• Semicircular arch
• Rectangular pillar
• Horseshoe codal arch
• Roll modillion

Decoration and Structural Logic

Decoration features vegetal, geometrical, and calligraphic motives. The section of the pillar becomes wider to make it higher; otherwise, the columns would collapse, which is the primary reason for... Continue reading "Islamic Architecture in Al-Andalus: Umayyad to Nasrid" »

Aircraft Identification Features

Learn to distinguish different aircraft models by their key visual characteristics:

• A330 vs B777: The B777 doesn’t have winglets, has three wheels per main landing gear strut, and the end of the fuselage is distinct.
• A320 vs B737: Standard Airbus/Boeing differences; B737s have a distinct engine shape (flattened bottom).
• B737 Series: Differences between -200, -300, -400, -500, -600, -700, -800, -900ER are primarily by size.
• B747: All have 4 engines. -200 and -300 do not have winglets, but the -300 has a larger upper deck hump. The -400 has winglets. The SP variant has no winglets and is shorter than others.
• B757: The -300 is significantly larger than the -200.
• B767: The -200 has no winglets. The -400 and -300 have

Common Characteristics of Machines

• Involve a kind of motion.
• Involve a kind of force.
• Make a job easier to do.
• Need some kind of input to make them work.
• Produce some kind of output.

Basic Types of Motion

• Rotary: Going round and round.
• Oscillating: Swinging backwards and forwards.
• Linear: In a straight line.
• Reciprocating: Backwards and forwards in a straight line.

A machine is a device that helps make work easier to perform.

Mechanical Advantage Defined

Mechanical Advantage: When a machine takes a small input force and increases the magnitude of the output force, a mechanical advantage has been produced.

Conservation of Energy Principle

Conservation of Energy: No machine can produce more work than the amount of work that is put into the machine.

The Six Simple

Common Cyberattacks and Threats

• Cyberattack: An attempt to damage or gain unauthorized access to systems — intento de dañar o acceder sin permiso
• Phishing: Fraudulent messages used to steal user credentials — mensajes falsos para robar datos
• Malware: Malicious software designed to harm systems — software que daña sistemas
• Ransomware: Malware that encrypts data and demands payment — programa que cifra datos y pide dinero

Advanced Attacker Techniques

• Lateral movement: Moving through a network to access other systems — moverse por la red para acceder a otros equipos
• Credential theft / harvesting: Stealing usernames and passwords — robo de usuarios y contraseñas
• Unauthorized access: Entering a system without permission — acceso sin permiso
• Social

Experiment 01: Network Traffic Analysis in ICS/SCADA

Tools

• Wireshark

Objectives

• Use Wireshark to capture and analyze network traffic to detect anomalies such as unauthorized commands or network scanning.

Deliverable

• A detailed report of traffic patterns and recommendations for mitigations.

Wireshark

Wireshark is a network protocol analyzer used to capture and inspect data packets in real time.

Installing Wireshark on Linux

1. Step 01: Update package lists: sudo apt update
2. Step 02: Install Wireshark: sudo apt install wireshark -y
3. Step 03: Allow non-root packet capture. When prompted, select to allow non-root users to capture packets. If not prompted, run:
   • sudo dpkg-reconfigure wireshark-common
   • sudo usermod -aG wireshark $USER
4. Step 04: Restart your session (log

Tubing and Hose Types

Rigid tubing: Stationary, straight runs.
Flexible hose: Used for movement and vibration.

Examples: Fuel, oil, hydraulic, oxygen, and instrument lines.

Tubing vs. Hose Measurement

Tubing: Measured by Outside Diameter (OD).
Hose: Measured by Inside Diameter (ID).

Size units: 1/16 inch increments.

• #6 = 6/16 = 3/8"
• #8 = 8/16 = 1/2"

Materials

Aluminum

• Low/medium pressure
• ~1000–1500 psi

Steel (CRES)

• High pressure
• 3000+ psi

Titanium

• Stronger and lighter

❌ Never use in oxygen systems due to combustion risk.

Fabricating Tubing

1. Cut
2. Deburr
3. Bend
4. Flare
5. Bead

Cutting Procedures

Use a tubing cutter.

• Tighten lightly
• Rotate
• Tighten gradually

❌ Warning: Too tight will deform the tube.

Deburring

Removes internal burrs to:

• Prevent flow restriction
• Prevent flare cracking
