system

Examples of system in the following topics:

• Inconsistent and Dependent Systems in Two Variables

  • For linear equations in two variables, inconsistent systems have no solution, while dependent systems have infinitely many solutions.
  • An inconsistent system has no solution, and a dependent system has an infinite number of solutions.
  • Systems that are not independent are by definition dependent.
  • We can apply the substitution or elimination methods for solving systems of equations to identify dependent systems.
  • We can also apply methods for solving systems of equations to identify inconsistent systems.

• Introduction to Systems of Equations

  • A system of equations consists of two or more equations in two or more variables, and solutions must satisfy all equations in the system at the same time.
  • To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that will satisfy all equations in the system at the same time.
  • A solution to the system above is given by
  • An inconsistent system has no solution.
  • A dependent system has infinitely many solutions.

• Expert Systems

  • An expert system consists of both an inference engine and a knowledge base and has decision-making abilities.
  • An expert system has a unique structure, different from traditional computer programs.
  • Knowledge-based systems are systems based on the methods and techniques of artificial Intelligence.
  • Knowledge base systems (KBS) go beyond the decision support philosophy to incorporate expert system technology into the decision-making framework.
  • Break down expert systems to the inference engine, the knowledge base, and conversational

• Comparing the Somatic and Autonomic Nervous Systems

  • The peripheral nervous system (PNS, see ) is divided into the somatic nervous system and the autonomic nervous system.
  • The somatic nervous system controls all voluntary muscular systems within the body, and also mediates involuntary reflex arcs.
  • The autonomic nervous system (ANS) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness and controlling visceral functions.
  • It is classically divided into two subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS).
  • The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system.

• The Systems Viewpoint

  • Systems thinking is an approach to problem solving that considers the overall system instead of focusing on specific parts of a system.
  • Systems thinking is the process of understanding how people and situations influence one another within a closed system.
  • In business, management also involves systems thinking.
  • Systems generally contain the following aspects:
  • Practitioners of systems thinking believe that the component parts of a system can best be understood, and best analyzed, in the context of their relationships with other parts of a system .

• Comparison of Enthalpy to Internal Energy

  • A thermodynamic system can be any physical system with a well-defined volume in space.
  • The outer edge of the system is referred to as its boundary, which often separates the system from the surroundings.
  • Hence, -q means the system loses heat, while +q means a system gains heat.
  • Similarly, +w means work is done on the system, while -w means work is done by the system.
  • However, in open systems, the pressure of the system and the surroundings has stayed constant.

• Introduction to the Nervous System

  • The basic unit of the nervous system is the neuron.
  • The nervous system can be divided into two major parts—the central nervous system (CNS) and the peripheral nervous system (PNS).
  • The peripheral nervous system includes a large system of nerves that are linked to the brain and spinal cord.
  • The PNS can be further subdivided into the autonomic nervous system and the somatic nervous system.
  • The nervous system of the human body, including the brain and spinal cord (central nervous system) and all the nerves of the body (peripheral nervous system).

• Plant Tissues and Organ Systems

• The Continental System

• The Factory System
