Low Dimensional Hamiltonian Systems
The theory of differential forms began with a discovery of Poincaré who found conservation laws of a new type for Hamiltonian systems—The Integral Invariants. Even in the absence of non-trivial integrals of motion, there exist invariant differential forms: a symplectic two-form, or a contact one-form for geodesic flows. Some invariant forms can be naturally considered as “forms on the quotient....
متن کاملDynamical Systems and Differential Forms . Low Dimensional Hamiltonian Systems
Theory of differential forms started from the discovery by H.Poincare' who found new type conservation laws for Hamiltonian systems-" The Integral Invariants ". Even if there are no nontrivial ordinary integrals of motion, there exist various invariant differential forms (f.e. symplectic 2-form is invariant for all hamiltonian systems and also one-form is invariant for geodesic flows). Restrict...
متن کاملLow-complexity synchronization algorithms for orthogonally modulated IR-UWB systems
Timing synchronization is a major issue for any communication system since it is essential to ensure its stable operation and reliable performance. In this paper, we compare two low-complexity synchronization algorithms for impulse radio ultra-wideband (IR-UWB) system, employing orthogonal pulse shape modulation (PSM). The two widely adopted modulation schemes for IR-UWB systems are binary puls...
متن کامل3-Dimensional conformal radiotherapy versus intensity modulated radiotherapy for localized prostate cancer: Dosimetric and radiobiologic analysis
Background: To analyze the dosimetric and radio biologic advantages between intensity modulated radiotherapy (IMRT) and 3 dimensional conformal radiotherapy (3DCRT) and selection of optimal photon energy for IMRT treatments. Material and methods: 24 patients with localized prostate carcinoma were planned for 3DCRT and IMRT techniques. Radiation dose of 54 Gy with 2 Gy/fraction, was planned to ...
متن کاملHot electrons in low-dimensional phonon systems
A simple bulk model of electron-phonon coupling in metals has been partially successful in explaining experiments on metal films that actually involve surfaceor other low-dimensional phonons. However, by an exact application of this standard model to a semi-infinite substrate with a free surface, making use of the actual vibrational modes of the substrate, we show that such agreement is fortuit...
