  1. Within a federal system the state or provincial governments share sovereignty with the central government and have final jurisdiction over a broad range of policy areas. Federal and unitary systems are ideal types, representing the endpoints of a continuum. Most countries fall somewhere in between the two extremes—states can be more or less ...

  2. Momentum space is the set of all momentum vectors p a physical system can have; the momentum vector of a particle corresponds to its motion, with units of [mass][length][time] −1. Mathematically, the duality between position and momentum is an example of Pontryagin duality.

  3. Oct 23, 2007 · Art should be defined only if there is a unitary concept of art that serves all of art’s various purposes – historical, conventional, aesthetic, appreciative, communicative, and so on. So, since there is no purpose-independent use of the concept of art, art should not be defined (Mag Uidhir and Magnus 2011; cf. Meskin 2008).

  4. Unitary freedom of square roots. If T is a non-negative operator on a finite-dimensional Hilbert space, then all square roots of T are related by unitary transformations. More precisely, if T = A*A = B*B, then there exists a unitary U such that A = UB. Indeed, take B = T 1 / 2 to be the unique non-negative square root of T.

  5. Next, we need to define the time domain for which we are going to perform the simulation and also the type of input function for which we want to observe the response. For out example we are going to simulate 20 s for a unitary step input (the step value is assigned at t = 0 s). t = 0:0.01:20; [ys,xs]=csim("step",t,sysMech);

  6. Necessary definition, being essential, indispensable, or requisite: a necessary part of the motor. See more.

  7. System approach is based on the generalization that everything is inter-related and inter-dependent. A system is composed of related and dependent element which, when in interaction, forms a unitary whole. A system is simply an assemblage or combination of things or parts forming a complex whole.
