INTRODUCTION: In the pharmaceutical industry, the temperature control processes range from research to production scale. To obtain high-quality reaction products, temperature control systems must reliably control the process sequence in an external reactor. The environment inside a pharmacy and pharmaceutical storage areas must be optimal and constant to ensure the effectiveness of the medications within them. Temperature and relative humidity should be controlled, monitored and recorded, where relevant, to ensure compliance with requirements pertinent to the materials and products, and to provide a comfortable environment for the operator where necessary. ·       Maximum and minimum room temperatures and relative humidity should be appropriate. ·       Temperature conditions should be adjusted to suit the needs of the operators while wearing their protective clothing. ·       The o...

In automobiles, there are varied chances of faults in the engines due to the changing temperature, speed, etc., but detecting of such faults can be laborious and time consuming. So using a PLC instead can ease the process. A Programmable Logic Controller (PLC) is a digital computer used for automation of electromechanical processes. Unlike general purpose computers PLC is designed for multiple inputs and outputs arrangement, extended temperature ranges, immunity to electrical noise, and resistance t...

Musical instruments work by outputting an electrical, electronic or digital  audio signal  that ultimately is plugged into a  power amplifier   which drives a   loudspeaker , creating the sound heard by the performer and listener . They must include a  user interface  for controlling its sound, often by adjusting the  pitch ,  frequency , or duration of each  note . Evolving through the ages it is increasingly common in electronic musical instruments to separate user interface and sound-generating functions into a  music controller  ( input device ) and a  music synthesizer , respectively, with the two devices communicating through a musical performance description language such as  MIDI  or  Open Sound Control , microprocessors and microcontrollers. ·        Microprocessors play a significant role in musical instruments, they are used to modify volume, attack, decay, and use ...
