Hidden Symmetries of M Theory [PDF]
, 1998 A worldvolume action for membrane is considered to study the target space local symmetries. We introduce a set of generators of canonical transformations to exhibit the target space symmetries such as the general coordinate transformation and the gauge ...

The Minkowski metric in non-inertial observer radar coordinates
, 2004 We give a closed expression for the Minkowski (1+1)-dimensional metric in the radar coordinates of an arbitrary non-inertial observer O in terms of O's proper acceleration.

Integral Control of Port-Hamiltonian Systems: Nonpassive Outputs Without Coordinate Transformation [PDF]
IEEE Transactions on Automatic Control, 2017 In this paper we present a method for the addition of integral action to nonpassive outputs of a class of port-Hamiltonian (pH) systems. The proposed integral controller is a dynamic extension, constructed from the open-loop system, such that the closed ...

Linear spin wave theory for single-Q incommensurate magnetic structures [PDF]
, 2015 Linear spin wave theory provides the leading term in the calculation of the excitation spectra of long-range ordered magnetic systems as a function of $1/\sqrt{S}$. This term is acquired using the Holstein-Primakoff approximation of the spin operator and

A general transformation formula for conformal fields
, 1994 An explicit transformation formula for chiral conformal fields under arbitrary holomorphic coordinate transformations is established. As an application I calculate the transformation law of the general quasiprimary field at level 4.Comment: 8 pages ...

Solving Einstein's Equations With Dual Coordinate Frames [PDF]
, 2006 A method is introduced for solving Einstein's equations using two distinct coordinate systems. The coordinate basis vectors associated with one system are used to project out components of the metric and other fields, in analogy with the way fields are ...

IEEE Access, 2022 This paper proposes hybrid mode control for an asymmetric dual three-phase synchronous motor (ADTP-SM) with separated neutral points in a single-phase open-fault situation. The fault-tolerant control is classified into the maximum torque mode and minimum

Transformation procedures in 3D terrestrial coordinate systems [PDF]
Acta Montanistica Slovaca, 2001 Transformation procedures belong to the main tasks of surveyor working in a field of geodesy, for example in satellite geodesy or astronomical geodesy.
