Chemical and kinematical evolution in nearby dwarf spheroidal galaxies
… and evolution of dSphs is the study of their kinematical properties. These low-mass galaxies are believed to be the smallest cosmological structures containing dark matter. By measuring radial velocities in the remote dSph Leo I I showed that the resulting velocity dispersion profile is …

The Kinematical Parameters of Minor Mergers and their Observational Traces
… we derived in cosmological simulations the kinematical properties of dark matter halos that are minor merging and their abundance in space and time. We found that minor merger were most likely at a time 7Gyrs ago and happened typically once for a Milky Way sized halo. Their pericenter …

A Kinematical Investigation of Some External Wind Tunnel Force Measurement Systems
<p>A discussion on the fundamental concepts associated with wind tunnel forces measurement systems (balances) is presented. Detailed static analyses are performed on the six component pyramidal, six component floating beam, and three component strain gaged strut balances. These static analyses lead …

Worldsheet methods for perturbative quantum field theory
… the ambitwistor amplitude gives the expected kinematical prefactor; matching this amplitude to the field theory expectation in a particular kinematical regime; solving the one loop scattering equations in this kinematical regime; a conjecture for the IR behaviour of the one-loop ambitwistor …

Distribution of baryonic and dark matter in spiral and irregular nearby galaxies
… the inner regions of galaxies, by connecting the kinematical data from the optical observations to the photometry data available in the literature. After summarizing the global properties of the luminous and DM of galaxies, I present the instruments based on the FabryPerot interferomter used to …

Measurement of inclusive Lambda / Antilambda hyperon polarisation in proton nucleus collisions at 920 GeV proton beam energy
… of approximately 2900 Lambdas was obtained in a kinematical region of transverse momentum p_t in [0.2,2.2] GeV/c and Feynman variable x_F in [-0.19,0.03] and roughly 1350 Antilambdas were found in the range of p_t in [0.12,1.64] GeV/c and x_F in [-0.13,0.01]. These samples were analysed for …

Modelo biomecânico de corpo inteiro com coordenadas naturais para análise de movimento humano
… system and joint angles calculated by a custom kinematical model. A multibody system model, based on redundant natural coordinates, was developed, containing 21 segments and 252 generalized coordinates. Anatomical joints were modeled through ball-and-socket, Cardan, hinge and contact surface …

Variational Principles in Finite Elasticity With Applications
… principles for elastic bodies subject to kinematical constraints such as incompressibility are formulated. The same approach can be used to obtain variational principles for infinitesimal deformations superposed on a known finite elastic deformation of an elastic body.

Structure Solution Using Precession Electron Diffraction and Diffraction Tomography
… consistent with the intensities becoming “more kinematical” in nature. The technique of automated diffraction tomography is developed. Transformations are derived which map the positions of diffraction maxima into three-dimensional reciprocal space following an automated peak detection process. …

Studies in the theory of solids
… model parameters are known ~ priori, both the kinematical and dynamical intensities are specified exactly without appeal to any empirical procedures. Comparison of the kinematical and averaged-dynamical intensities reveals systematic discrepancies between the two on the order of 10-100% for …

Hadronic matter: from vacuum to extreme temperature in the presence of magnetic fields
