ColSalle

description: El Colegio De La Salle de Bogotá busca constantemente estar a la vanguardia frente a los cambios educativos en el mundo y en Colombia mediante la innovación en estrategias pedagógicas y tecnológicas. Parte fundamental de su Proyecto Educativo Institucional es la implementación del bilingüismo, que desde el 2015 se ha ido consolidando en una Política de Educación Bilingüe. Si bien varios aspectos se contemplan allí, no se han establecido lineamientos para la enseñanza del proceso lectoescritor en inglés en etapa preescolar. Abordar esta problemática nos permite apoyar el quehacer docente, fortalecer el aprendizaje del idioma entreestudiantes y alcanzar los objetivos de Lenguas Extranjeras alineados a las políticas públicas del Ministerio deEducación Nacional y a los estándares del Marco Común Europeo.

On exotic sphere fibrations, topological phases, and edge states in physical systems

description: We suggest that exotic sphere fibrations can be mapped to band topologies in condensed matter systems. These fibrations can correspond to geometric phases of two double bands or state vector bases with second Chern numbers m+n and -n respectively. They can be related to topological insulators, magneto-electric effects, and photonic crystals with special edge states. We also consider time-reversal symmetry breaking perturbations of topological insulator, and heterostructures of topological insulators with normal insulators and with superconductors. We consider periodic TI/NI/TI/NI' heterostuctures, and periodic TI/SC/TI/SC' heterostuctures. They also give rise to models of Weyl semimetals which have thermal and electrical transports.

Superconductivity and Crystal Structure of the Palladium-Iron-Arsenides Ca10(Fe1-xPdxAs)10Pd3As8

description: The palladium-iron-arsenides Ca10(Fe1-xPdxAs)10(Pd3As8) were synthesized by solid state methods and characterized by X-ray powder and single crystal diffraction. The triclinic crystal structure (space group P-1) is isotypic to the homologue platinum 1038 type superconductors with alternating FeAs4/4- and Pd3As8-layers, each separated by layers of calcium atoms. Iron is tetrahedral and palladium is planar coordinated by four arsenic atoms. As2-dimers (dAs-As = 250 pm) are present in the Pd3As8-layer. Even though each layer itself has a fourfold rotational symmetry, the shifted layer stacking causes the triclinic space group. Resistivity measurements of La-doped samples show the onset of superconductivity at 17 K and zero resistivity below 10 K. The magnetic shielding fraction is about 20 % at 3.5 K. 57Fe-Mössbauer spectra exhibit one absorption line and show no hint to magnetic ordering. The electronic structure is very similar to the known iron-arsenides with cylinder-like Fermi surfaces and partial nesting between hole- and electron-like sheets. Our results show that superconductivity in the palladium-iron-compounds is present but complicated by too high substitution of iron by palladium in the active FeAs-layers. Since the electronic preconditions are satisfied, we expect higher critical temperatures in Pd1038-compounds with lower or even without Pd-doping in the FeAs-layer.

description: Strenuous physical activity in extreme environments is an important part of the activities of military personnel. The average infantry combat load for an infantry on the loaded tasks. Subjects performed an outdoor 4.8-km run and four maximal treadmill tests wearing the loads listed above. Subjects' pulmonary function was tested with load prior to each treadmill session. Peak values of heart rate, VO2, exercise ventilation, and respiratory exchange ratio were measured at the end of each maximal treadmill test. Significant decreases were found in pulmonary function measures (FEV1, FVC and MVV) with increasing load. Most peak responses during treadmill exercise, VO2peak, HRpeak, and VEpeak, decreased with increasing load. However, RERpeak did not decrease, which was unexpected. More research is needed to explain the lack of decrease in RERpeak. The ratio of VEpeak to MVV remained constant with increasing load, suggesting that the decreased performance with load was due to a limitation in breathing capacity. There was not a strong correlation between body mass or lean body mass and performance on the loaded treadmill tasks. The only exception to this was that males showed significant correlation between body mass and performance on the 30-kg trial. More research needs to be done with a group of subjects of more uniform fitness level to determine if loaded treadmill tests show a more significant correlation with body mass. Also, this study confirmed that an unloaded distance run is strongly related to unloaded uphill treadmill performance, but is more poorly related as load is increased on the treadmill test, suggesting that traditional unloaded run tests are not an effective means of evaluating aerobic perfom1ance for military field operations.

description: Within the framework of a constrained Minimal Supersymmetric Standard Model (cMSSM) augmented by an MSSM singlet-pair sector to account for the non-zero neutrino masses by inverse seesaw mechanism, the lightest supersymmetric particle (LSP) can be a mixed sneutrino with mass as small as 50 GeV, satisfying all existing constraints, thus qualifying as a light dark matter candidate. We study the possibility of the lightest neutral Higgs boson in this model decaying invisibly into a pair of sneutrino LSPs, thereby giving rise to novel missing energy signatures at the LHC. We perform a two-parameter global analysis of the LHC Higgs data available till date to determine the optimal invisible Higgs branching fraction in this scenario, and obtain a $2σ(1σ)$ upper limit of 0.23 (0.12). A detailed cut-based analysis is carried out thereafter, demonstrating the viability of our proposed signal vis-a-vis backgrounds at the LHC.

description: We show that the dynamics of a driven quantum system weakly coupled to the environment can exhibit two distinct regimes. While the relaxation basis is usually determined by the system+drive Hamiltonian (system-governed dynamics), we find that under certain conditions it is determined by specific features of the environment, such as, the form of the coupling operator (environment-governed dynamics). We provide an effective coupling parameter describing the transition between the two regimes and discuss how to observe the transition in a superconducting charge pump.

After the frequency analysis of the light curves, we confirmed the fundamental frequency of $f = 5.28677\ cd^{-1}$, together with 8 harmonics of the fundamental frequency, 7 of which are newly detected. No additional frequencies were detected. The O-C diagram, produced with the 21 newly determined times of maximum light combined with those provided in the literature, helps to obtain a new ephemeris formula of the times of maximum light with the pulsation period of $0.189150355 \pm 0.000000003\ days$.

description: We use multi-epoch near-infrared observations from the VISTA survey of the Magellanic Cloud system (VMC) to measure the proper motion of stars of the LMC, in one tile of 1.5 deg^2 centred at (alpha, delta) = (05:59:23.136, -66:20:28.68) and including the South Ecliptic Pole, with respect to their 2MASS position over a time baseline of ~10 years and from VMC observations only, spanning a time range of ~1 year. Stars of different ages are selected from the (J-Ks) vs. Ks diagram and their average coordinate displacement is computed from the difference between Ks band observations for stars as faint as Ks=19 mag. Proper motions are derived by averaging up to seven 2MASS-VMC combinations in the first case and from the slope of the best fit line among the seven VMC epochs in the second case. Separate proper motion values are obtained for variable stars in the field. The proper motion of ~40,000 LMC stars in the tile, with respect to ~8000 background galaxies, obtained from VMC data alone, is mu_alpha cos(delta) = +2.20+/-0.06 (stat) +/-0.29 (sys) and mu_delta = +1.70+/-0.06 (stat) +/-0.30 (sys) mas/yr. This value agrees with recent ground-based determinations in a nearby field but is larger than studies with the HST; the cause of this discrepancy may be due to additional systematic errors in the data. The LMC proper motion is also clearly distinct from the proper motion derived for stars of the Milky Way. The relative proper motion between the foreground stars and the LMC stars is ~5 mas/yr. Furthermore, we measure a decrease of the proper motion with increasing logarithm of stellar age for LMC stars. This study, based on just one VMC tile, shows the potential of the 2MASS-VMC and VMC-VMC combinations for a comprehensive investigation of the proper motion across the Magellanic system. (Abridged)

Theoretical investigation of acceleration of a turbojet engine

description: The failure of turbojet aircraft propulsion units to accelerate rapidly to high thrust operation when emergencies arise in slow speed flight has restricted their use in aircraft applications, and has also concentrated considerable attention upon their acceleration characteristics in an effort to produce better results. This thesis presents a method of computing the acceleration of a particular turbojet by making use of complete performance curves of the component parts of the turbojet.

The method presented here does not permit computation of the acceleration for a particular operating condition as determined by those variables usually considered independent; namely, (1) Flight conditions of velocity, density, pressure, and temperature, (2) Engine rotor speed (3) Fuel rate of flow, and (4) Tail cone area ratio. Computation using these four independent variables was originally attempted in preparation of this thesis. However, extreme complication in the computations dictated that turbine inlet temperature and air mass rate of flow, which are normally dependent variables, should be considered independent. Fuel rate of flow and tail cone area ratio are therefore considered dependent. Therefore, in order to match a particular operating condition it is necessary to make a family of computations for various turbine inlet temperatures (constant for each set) over a range of assumed air mass flows.

Computations have been performed for the Westinghouse X19B axial flow turbojet to illustrate application of the method and to show qualitative and quantitative effects of variation of tail area ratio, at two different turbine inlet temperatures.

description: A lattice gauge theory framework for simulations on graphic processing units (GPUs) using NVIDIA's CUDA is presented. The code comprises template classes that take care of an optimal data pattern to ensure coalesced reading from device memory to achieve maximum performance. In this work we concentrate on applications for lattice gauge fixing in 3+1 dimensional SU(3) lattice gauge field theories. We employ the overrelaxation, stochastic relaxation and simulated annealing algorithms which are perfectly suited to be accelerated by highly parallel architectures like GPUs. The applications support the Coulomb, Landau and maximally Abelian gauges. Moreover, we explore the evolution of the numerical accuracy of the SU(3) valued degrees of freedom over the runtime of the algorithms in single (SP) and double precision (DP). Therefrom we draw conclusions on the reliability of SP and DP simulations and suggest a mixed precision scheme that performs the critical parts of the algorithm in full DP while retaining 80-90% of the SP performance. Finally, multi-GPUs are adopted to overcome the memory constraint of single GPUs. A communicator class which hides the MPI data exchange at the boundaries of the lattice domains, via the low bandwidth PCI-Bus, effectively behind calculations in the inner part of the domain is presented. Linear scaling using 16 NVIDIA Tesla C2070 devices and a maximum performance of 3.5 Teraflops on lattices of size down to 64^3 x 256 is demonstrated.

description: We present a first-principles derivation of the Markovian semi-group master equation without invoking the rotating wave approximation (RWA). Instead we use a time coarse-graining approach which leaves us with a free timescale parameter, which we can optimize. Comparing this approach to the standard RWA-based Markovian master equation, we find that significantly better agreement is possible using the coarse-graining approach, for a three-level model coupled to a bath of oscillators, whose exact dynamics we can solve for at zero temperature. The model has the important feature that the RWA has a non-trivial effect on the dynamics of the populations. We show that the two different master equations can exhibit strong qualitative differences for the population of the energy eigenstates even for such a simple model. The RWA-based master equation misses an important feature which the coarse-graining based scheme does not. By optimizing the coarse-graining timescale the latter scheme can be made to approach the exact solution much more closely than the RWA-based master equation.

description: We present our photometric studies of the newly discovered optical transient, OT J012059.6+325545, which underwent a large outburst between 2010 November and 2011 January. The amplitude of the outburst was about 8 mag. We performed simultaneous multi-color photometry by using g', Rc, and i'-band filters from the early stage of the outburst. The time resolved photometry during the early stage revealed periodic variations with double-peaked profiles, which are referred to as early superhumps, with amplitudes of about 0.08 mag. After the rapid fading from the main outburst, we found rebrightening phenomena, which occurred at least nine times. The large amplitude of the outburst, early superhumps, and rebrightening phenomena are typical features of WZ Sge-type dwarf novae. We detected color variations within the early superhump modulations making this only the second system, after V445 And, for which this has been established. We carried out numerical calculations of the accretion disk to explain both of the modulations and the color variations of the early superhump. This modeling of the disk height supports the idea that height variations within the outer disk can produce the early superhump modulations, though we cannot rule out that temperature asymmetries may also play a role.

Actuation, propagation, and detection of transverse magnetoelastic waves in ferromagnets
Creators: name: Kamra, Akashdeep
name: Bauer, Gerrit E. W.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We study propagation of ultrasonic waves through a ferromagnetic medium with special attention to the boundary conditions at the interface with an ultrasonic actuator. In analogy to charge and spin transport in conductors, we formulate the energy transport through the system as a scattering problem. We find that the magneto-elastic coupling leads to a non-vanishing magnetic (elastic) energy accompanying the acoustic (spin) waves with a resonantly enhanced effect around the dispersion relation anti-crossing point. We demonstrate the physics of excitation of magnetization dynamics via acoustic waves injection around the ferromagnetic resonance frequency.

Vortex formation and shedding from a two-dimensional, thin, flat plate parallel to the free stream
Creators: name: Bauer, Andrew Burkhard
Publisher: name: California Institute of Technology
Year: 1959
Subjects: Aeronautics

description: Vortex formation and shedding from the trailing edge of a two-dimensional, thin, flat plate parallel to the free stream is studied experimentally for the case of incompressible flow.  Consideration of the classical boundary layer theory, the Karman vortex-street theory, the formation of the vortex centers, and some annihilation of vorticity in the free shear layers leads to an estimate of Strouhal number.  This estimate is in reasonable agreement with experiment.  The flow phenomena of a splitter plate mounted aft of the main plate and of a NACA 0012 airfoil are also observed experimentally and are found to be in essential agreement with applicable portions of the theory.

A critical study of spin-up drag loads on aircraft landing gears
Creators: name: Brown, John R.
Publisher: name: California Institute of Technology
Year: 1949
Subjects: Aeronautics

description: This report attempts to analyze in detail the spin-up drag loads imposed upon an aircraft main landing gear.  Other factors in the landing gear problem are ignored except insofar as they affect this one type of loading.  As an instrument for study, one model of aircraft was chosen for which extensive flight test and drop test data were available.

The main parameters which enter into the spin-up drag load are the landing weight of the aircraft, the rate of descent at contact, the ground speed, the time interval from initial contact to attainment of maximum vertical load, and the coefficient of friction between the tire and the runway surface.  Minor parameters which may affect the drag load are the tire pressure, moment of inertia of the rolling stock, oleo pressure, and quantity of oil in the hydraulic shock absorber.

The results of this study indicate that the maximum gear drag load is primarily a function of the time required to reach maximum vertical load, and that further study of this parameter, using drop test data for several types of aircraft, might well lead to some valuable empirical information essential to landing gear design.  The value of the coefficient of friction was seen to vary widely in test landings but a maximum value of 0.55 appears to be satisfactory for limit design calculations.

description: Plywood and other laminated panels are used as substitutes for solid wood in various applications. There is a special interest for the densified wood veneers to produce such composites. In this chapter selected properties of densified veneers made of two fast-growing species are presented along with a new lay-up veneer structure of plywood to produce value-added panels for indoor applications. Based on the findings of this study the densification process enhanced the veneer surface quality and gloss, giving also a pleasant darker colour to the veneers and the plywood made of them. The new plywood structure with alternate layers of densified and non-densified veneers was proved to be an efficient solution to obtain panels with improved properties.

description: We construct an algorithm to determine all stationary axi-symmetric solutions of 3-dimensional Einstein gravity with a minimally coupled self-interacting scalar field. We holographically renormalize the theory and evaluate then the on-shell action as well as the stress tensor and scalar one-point functions. We study thermodynamics, derive two universal formulas for the entropy and prove that global AdS provides a lower bound for the mass of certain solitons. Several examples are given in detail, including the first instance of locally asymptotically flat hairy black holes and novel asymptotically AdS solutions with non-Brown-Henneaux behavior.
