Cold junction compensation (CJC) is a technique used to correct the measurement of temperature using a thermocouple. A thermocouple is a device that consists of two different conductors joined at one end, which generates a voltage in response to a temperature difference between the two conductors. The voltage generated by the thermocouple is known as the thermoelectric voltage or the Seebeck vol..

RTDs, or resistance temperature detectors, are temperature sensors that measure temperature by determining the resistance of a material as its temperature changes. RTDs are commonly made of materials such as copper, nickel, or platinum, which have a predictable change in resistance as their temperature changes. RTDs are widely used in a variety of applications, including industrial process contr..

The Seebeck effect is a phenomenon that occurs when there is a temperature difference between two ends of a conductor, and a voltage is generated along the conductor as a result. This voltage is called the thermoelectric voltage or the Seebeck voltage. The Seebeck effect is named after Thomas Johann Seebeck, who discovered it in 1821. Seebeck found that when a conductor made of a metallic alloy ..

Heap에 대해서 Haep memory 공격등을 학습하다 보면 Chunk라는 개념이 등장한다. 여기서 Chunk란 header와 data 영역으로 구성된다. - malloc()으로 할당 받는 영역과 header를 포함한 영역을 뜻한다. - header란 prev_size와 size를 뜻한다. - 32bit에서는 8byte의 배수, 64bit에선 16byte의 배수로 할당이 된다. - 64bit에서 malloc(1)을 하게되면 Data영역은 총 16만큼 할당이 된다는 의미다. prev_size - 이전 청크의 크기이다. - 위 그림에서 2번 청크를 기준으로 이전 청크는 1번 청크이며, 1번 청크의 플래그를 제외한 크기이다. - Data의 크기가 128비트 이상인 청크가 free될 때 다음 청크의 prev_..
