An ancient hydraulic telegraph being used by Aeneas to send a message. A hydraulic telegraph ( Greek : υδραυλικός τηλέγραφος ) refers to two different semaphore systems involving the use of water-based mechanisms as a telegraph .
Typical hydraulic load cell applications include tank, bin, and hopper weighing. [6] By example, a hydraulic load cell is immune to transient voltages (lightning) so these type of load cells might be a more effective device in outdoor environments. This technology is more expensive than other types of load cells.
Hydraulic fuses are in-line safety devices designed to automatically seal off a hydraulic line if pressure becomes too low, or safely vent fluid if pressure becomes too high. Auxiliary valves in complex hydraulic systems may have auxiliary valve blocks to handle various duties unseen to the operator, such as accumulator charging, cooling fan ...
A model of communication is a simplified presentation that aims to give a basic explanation of the process by highlighting its most fundamental characteristics and components. [16] [8] [17] For example, James Watson and Anne Hill see Lasswell's model as a mere questioning device and not as a full model of communication. [10]
Business communication is the act of information being exchanged between two-parties or more for the purpose, functions, goals, or commercial activities of an organization. [1] Communication in business can be internal which is employee-to-superior or peer-to-peer, overall it is organizational communication.
Poole's multiple sequence model is a communication theory approach developed by Marshall Scott Poole in 1983. [1] The model focuses on decision making processes in groups, and rejects other widely held communication theories in favor of less linear decision making processes.
A major part of this network will consist of interconnected pipes. This network creates a special class of problems in hydraulic design, with solution methods typically referred to as pipe network analysis. Water utilities generally make use of specialized software to automatically solve these problems.
A module with two input streams at the top, an AND output bucket in the middle, and an XOR output stream at the bottom.. Fluidics, or fluidic logic, is the use of a fluid to perform analog or digital operations similar to those performed with electronics.
