Proposed method of Hurwitz-Radon Matrices (MHR) is applied in curve modeling via different coefficients: polynomial, sinusoidal, cosinusoidal, tangent, cotangent, logarithmic, exponential, arcsin, arccos, arctan, arcctg or power. where the branches of the arctan function must be taken appropriately.
Preliminary hearings and arraignments both occur before your trial, but have different purposes. The preliminary hearing is where the judge decides if there is enough evidence mounted against you for you to stand trial. The arraignment is where you can file your plea of guilty, not guilty, or no contest.
Arraignment: Essentially identical to District Court arraignment. If a plea agreement has been worked out, the defendant enters the guilty plea and allocutes (tells the judge what he did). Many courts skips this phase of the case.
