Introduction to Edge Computing

  INTRODUCTION TO EDGE COMPUTING ImageSource: https://devops.com/is-your-infrastructure-ready-for-edge-computing/   What is Edge Computing? Edge computing brings computation and data storage closer to the devices where it’s being gathered, rather than relying on a central location that can be thousands of miles away. This is done so that data, especially real-time data, does not suffer latency issues that can affect an application’s performance.    In addition, companies can save money by having the processing done locally, reducing the amount of data that needs to be processed in a centralized location. Edge computing was developed due to the exponential growth of IoT devices, which connect to the internet for either receiving information from the cloud or delivering data back to the cloud.      Why does Edge computing matter? Before edge computing, a smartphone scanning a person’s face for facial recognition would need to run the facial recognition a...

Introduction to Control Valves

  A control valve , also known as a Final Control Element , is a valve that controls fluid flow by changing the size of the flow passage in response to a controller signal. This allows for direct control of flow rate and, as a result, process variables like pressure, temperature, and liquid level.   The question here is why these control valves are needed? Process plants are made up of thousands of control loops that are all interconnected just to create a product that can be sold. Each of these control loops is aimed at keeping process variables like pressure, flow, etc within a specified operating range in order to ensure the end product's quality. Each of these loops creates disturbances that have a negative impact on the process variable, and connections with other loops in the network generate disturbances that have an effect on the process variable. Sensors and transmitters gather information about the process variable and its connection to some desired set point to redu...
