Natanz nuclear facility. The attack was aimed at industrial SCADA controllers and was a stand-alone attack. It was not an attack that required access to the Internet. The attackers relied on local networks and USB drives to carry out the attack. It targeted Siemens controllers and underwent a complex process to make sure that it found the correct target. Once the target was found‚ malicious code was entered into the controller‚ which caused their centrifuges to become over-pressurised and break

低圧蒸気の需要が現状の供給量より上回る場合、高圧蒸気のラインから蒸気を低圧蒸 気のラインに流して需要を満たす。このとき、高圧蒸気のラインから低圧蒸気ライン に流す蒸気の量は低圧蒸気の圧力がある所定の値（設定値）になるように決める。 (b) 高圧蒸気の圧力が規定の上限値を超えそうになる場合は緊急避難に、高圧蒸気の圧力 を上限値以下に戻すように、高圧蒸気ラインから低圧蒸気ラインに蒸気を流す。 HSS ：High selector switch PC 高圧蒸気のライン 低圧蒸気のライン 図2.29 スチーム用役系のオーバライド制御 ：Pressure controller 鉄鋼の高炉制御について調査し、A4、1 枚程度にまとめよ。 必ず、出典（参考文献等）を記述すること。（参考：鉄鋼における制御、など） No.4 Process Control Homework Text p.51 [2] [3] [2] The process in Fig.2.28 heats and cracks the naphtha in heating oven.

AUTOMATIC TEMPERATURE CONTROLLED FAN H ere is a circuit through which the speed of a fan can be linearly controlled automatically‚ depending on the room temperature. The circuit is highly efficient as it uses thyristors for power control. Alternatively‚ the same circuit can be used for automatic temperature controlled AC power control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at

2.2 Definition of a Microcontroller Microcontroller‚ as the name suggests‚ are small controllers. They are like single chip computersthat are often embedded into other systems to function as processing/controlling unit. For example‚ the remote control you are using probably has microcontrollers inside that do decodingand other controlling functions. They are also used in automobiles‚ washing machines‚microwave ovens‚ toys ... etc‚ where automation is needed.The key features of microcontrollers include:
