The Modular Distributed Manipulator System (MDMS) is a macroscopic actuator array which can manipulate objects in the plane. The piecewise-constant dynamics of manipulation on the MDMS are developed based on an exact discrete representation of the system. The resulting dynamics are inverted enabling the calculation of an open-loop vector eld which provides arbitrary uniform object dynamics. The...

This study is situated in an educational context where secondary Latinx English learners’ enrollment has dramatically increased. However, many face limited access to quality education and lack the skills be college career-ready. To tackle this problem, Language Development–Content-Based Teaching Learning (ELD–CBTL) model designed implemented help shift teachers’ knowledge, beliefs, attitudes, p...

We construct left invariant special Kähler structures on the cotangent bundle of a flat pseudo-Riemannian Lie group. introduce twisted cartesian product two algebras according to linear representations by infinitesimal transformations. also exhibit double extension process algebra which allows us get all simply connected groups with bi-invariant symplectic connections. All constructed performin...

In addition to optimal conditions, invariant laws of Lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 GeV/c. By normalizing the differential cross-section to unity, the magnitudes of helicity amplitudes and the angle between them are dete...

This paper deals with Multiple Input Multiple Output systems for active control of acoustic signals. These systems are used when the acoustic eld is complex and therefore a number of sensors are necessary to estimate the sound eld and a number of sources to create the cancelling eld. A steepest descent iterative algorithm is applied to minimise the p-norm of a vector composed by the output sign...

This paper investigates the evolution of the state vector of a charged quantum particle in a harmonic oscillator driven by a time-dependent electric eld. The external eld randomly oscillates and its amplitude is small, but it acts long enough so that we can solve the problem in the asymptotic framework corresponding to a eld amplitude which tends to zero and a eld duration which tends to innnit...
