- Hydrophobic > 90 degree

- Super-Hydrophobic > 150 degree 

- Oleophobic > 90 degree, oil in water

- Super-Oleophobic > 150 degree, oil in water

Ultrasonic Machining (USM)

• The hole oversize diameter is oversize than the drill hole diameter
•  A hole conicity of approximately 0.2° arises when drilling a 20-mm-diameter hole to a depth of 10 mm in graphite.

• Out of roundness, arises by lateral vibration and arise due to the out of perpendicularity of the tool face and the tool centerline and when the acoustic parts of the machine are misaligned
• Typical roundness errors are about 40 to 140 μm and 20 to 60 μm, respectively, for glass and graphite materials

• Smoother surfaces can also be obtained when the viscosity of the liquid carrier of the abrasive slurry is reduced

BACKDOOR Detection and Audit

 # 1. Check for suspicious processes

ps aux | grep -v ']$' | less

# 2. Check listening ports

sudo netstat -tunlp

# 3. Check for unauthorized SSH keys

cat ~/.ssh/authorized_keys

# 4. Check system logs

sudo journalctl -xe | grep -i "failed\|error\|backdoor"

# 5. Check for rootkits

sudo apt install rkhunter chkrootkit

sudo rkhunter --check

sudo chkrootkit
