The Nyquist plot for () = + + with s = jω.. In control theory and stability theory, the Nyquist stability criterion or Strecker–Nyquist stability criterion, independently discovered by the German electrical engineer Felix Strecker [] at Siemens in 1930 [1] [2] [3] and the Swedish-American electrical engineer Harry Nyquist at Bell Telephone Laboratories in 1932, [4] is a graphical technique ...
The following diagnostic systems and rating scales are used in psychiatry and clinical psychology.This list is by no means exhaustive or complete. For instance, in the category of depression, there are over two dozen depression rating scales that have been developed in the past eighty years.
Fig 1: Typical example of Nyquist frequency and rate. They are rarely equal, because that would require over-sampling by a factor of 2 (i.e. 4 times the bandwidth). In signal processing , the Nyquist rate , named after Harry Nyquist , is a value equal to twice the highest frequency ( bandwidth ) of a given function or signal.
Early uses of the term Nyquist frequency, such as those cited above, are all consistent with the definition presented in this article.Some later publications, including some respectable textbooks, call twice the signal bandwidth the Nyquist frequency; [6] [7] this is a distinctly minority usage, and the frequency at twice the signal bandwidth is otherwise commonly referred to as the Nyquist rate.
Some depression rating scales are completed by patients. The Beck Depression Inventory, for example, is a 21-question self-report inventory that covers symptoms such as irritability, fatigue, weight loss, lack of interest in sex, and feelings of guilt, hopelessness or fear of being punished. [11]
Multiple convenience and random samples, as well as research studies in both clinical and nonclinical sample [22] [1] [23] Internal consistency (Cronbach's alpha, split half, etc.) Good Cronbach's alpha reported at .88 for measuring depression [22] Inter-rater reliability: Good Kappas range from .64-.81 for depression. [24] Kappa for anxiety is ...
In the control system theory, the Routh–Hurwitz stability criterion is a mathematical test that is a necessary and sufficient condition for the stability of a linear time-invariant (LTI) dynamical system or control system. A stable system is one whose output signal is bounded; the position, velocity or energy do not increase to infinity as ...
Recent studies however, have found that dysthymic disorder and depressive personality disorder are not as comorbid as previously thought. It was found that almost two thirds of the test subjects with depressive personality disorder did not have dysthymic disorder, and 83% did not have early-onset dysthymia. [1]
