Controllability and observability are dual aspects of the same problem. Roughly, the concept of controllability denotes the ability to move a system around in its entire configuration space using only certain admissible manipulations. The exact definition varies slightly within the framework or the type of models applied.
Nursing assessment is the gathering of information about a patient's physiological, psychological, sociological, and spiritual status by a licensed Registered Nurse. Nursing assessment is the first step in the nursing process. A section of the nursing assessment may be delegated to certified nurses aides.
Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals. The concept of observability was introduced by the Hungarian-American engineer Rudolf E. Kálmán for linear dynamic systems.
Controllability and observability are main issues in the analysis of a system before deciding the best control strategy to be applied, or whether it is even possible to control or stabilize the system. Controllability is related to the possibility of forcing the system into a particular state by using an appropriate control signal.
The original purpose of the model was to be an assessment used throughout the patient's care, but it has become the norm in UK nursing to use it only as a checklist on admission. It is often used to assess how a patient's life has changed due to illness or admission to hospital rather than as a way of planning for increased independence and ...
The observability and controllability of a system are mathematical duals (i.e., as controllability provides that an input is available that brings any initial state to any desired final state, observability provides that knowing an output trajectory provides enough information to predict the initial state of the system).
A nursing diagnosis may be part of the nursing process and is a clinical judgment about individual, family, or community experiences/responses to actual or potential health problems/life processes. Nursing diagnoses foster the nurse's independent practice (e.g., patient comfort or relief) compared to dependent interventions driven by physician ...
The nursing process is a modified scientific method which is a fundamental part of nursing practices in many countries around the world. [1] [2] [3] Nursing practise was first described as a four-stage nursing process by Ida Jean Orlando in 1958. [4] It should not be confused with nursing theories or health informatics. The diagnosis phase was ...
