Nonlinear dynamics in superlattices driven by high frequency ac-fields

We investigate the dynamical processes taking place in nanodevices driven by high-frequency electromagnetic fields. We want to elucidate the role of different mechanisms that could lead to loss of quantum coherence. Our results show how the dephasing effects of disorder that destroy after some periods coherent oscillations, such as Rabi oscillations, can be overestimated if we do not consider the electron-electron interactions that can reduce dramatically the decoherence effects of the structural imperfections. Experimental conditions for the observation of the predicted effects are discussed.Comment: REVTEX (8 pages) and 4 figures (Postscript

Course Development: Advanced Audio Content Creation

The goal of this portfolio is to develop BRDC 391 Special Topics: Advanced Audio Content Creation into a permanent course that serves as an extension of BRDC 227 and supports advanced learning in audio production. The College of Journalism and Mass Communications has expressed a need for an advanced audio offering as interest in audio production has surged with the popularity of podcasting and audiobook production. The course centers around concept creation, hardware and software use, writing, vocal performance, and editing to create professional-level audio productions. This portfolio documents the development of Advanced Audio Content Creation and the student learning achieved in the course in Spring 2022 to help make the case for giving the course a permanent course number and a regular rotation in the curriculum as an elective

AUTOMATED METHOD OF NOISE REMOVAL FROM MULTICHANNEL AUDIO

An automated system and method are disclosed for the removal of background noise from audio signals. The system takes input of multiple recordings of the same event and gives an output of a single audio stream. This audio stream emphasizes the common components of the inputs and attenuates components that are not perceived in all the recordings. The method removes constant background noise and shorter impulse noises effectively through , audio preprocessing, noise detection and attenuation, and final signal synthesis. Any video or audio editing software could use this method to create clearer audio signals with less background noise

METHOD FOR IMPLEMENTING AUTOMATED FUSION OF MULTIPLE AUDIOVISUAL RECORDINGS

A system and method for implementing automated fusion of multiple recordings of an event by using video processing is disclosed. The application determines the best camera angle from the available recordings for viewing important parts of the event and allows the user to automatically generate a fused version from the several recordings. The method includes video synchronization, tracking and clustering tracked objects in the video, followed by optimum video feed inference. The method greatly reduces time and eliminates manual effort, as processes such as identifying the best quality among different versions available, sequencing various clips correctly, and fusing them seamlessly are all automated

Le tourisme en Haïti : analyse de la structure d'hébergement

La première élection démocratique en Haïti, avait redonné confiance aux Haïtiens en leur potentiel de développement. Aujourd'hui, l'enthousiasme du peuple s'est refroidi. Les Nations Unies, par l'intermédiaire de consultants internationaux, travaillent à reconstruire une industrie touristique rentable et originale en Haïti. Sur la scène internationale, l'industrie touristique haïtienne souffre d'une image négative. Pourtant, la majorité des intervenants de l'industrie touristique croient que le tourisme sera l'activité qui contribuera le plus à la création d'emplois en Haïti d'ici les deux prochaines décennies. L'objectif principal de ce mémoire consiste à poser un diagnostic éclairé sur l'état de la structure d'hébergement dans les six zones touristiques d'Haïti et à faire des recommandations dans l'esprit des divers plans de développement de la Secrétairerie d'état au tourisme. Ainsi, le premier objectif spécifique est d'analyser la structure d'hébergement pour l'ensemble du pays. Le second objectif spécifique est d'analyser la vision de développement touristique envisagée par les autorités. Le troisième objectif spécifique est d'analyser la structure d'hébergement d'une région en particulier, en l'occurrence Jacmel/Marigot. Finalement, le quatrième objectif spécifique est de dresser un inventaire des attraits touristiques de cette région

Multiphoton Quantum Optics and Quantum State Engineering

We present a review of theoretical and experimental aspects of multiphoton quantum optics. Multiphoton processes occur and are important for many aspects of matter-radiation interactions that include the efficient ionization of atoms and molecules, and, more generally, atomic transition mechanisms; system-environment couplings and dissipative quantum dynamics; laser physics, optical parametric processes, and interferometry. A single review cannot account for all aspects of such an enormously vast subject. Here we choose to concentrate our attention on parametric processes in nonlinear media, with special emphasis on the engineering of nonclassical states of photons and atoms. We present a detailed analysis of the methods and techniques for the production of genuinely quantum multiphoton processes in nonlinear media, and the corresponding models of multiphoton effective interactions. We review existing proposals for the classification, engineering, and manipulation of nonclassical states, including Fock states, macroscopic superposition states, and multiphoton generalized coherent states. We introduce and discuss the structure of canonical multiphoton quantum optics and the associated one- and two-mode canonical multiphoton squeezed states. This framework provides a consistent multiphoton generalization of two-photon quantum optics and a consistent Hamiltonian description of multiphoton processes associated to higher-order nonlinearities. Finally, we discuss very recent advances that by combining linear and nonlinear optical devices allow to realize multiphoton entangled states of the electromnagnetic field, that are relevant for applications to efficient quantum computation, quantum teleportation, and related problems in quantum communication and information.Comment: 198 pages, 36 eps figure

Calidad de sentencias de primera y segunda instancia sobre delitos contra la vida, el cuerpo y la salud - homicidio culposo, en el expediente N° 00194-2010-0- 0206JR-PE-01, del distrito judicial de Ancash – Huari, 2017.

La investigación tuvo como objetivo general, determinar la calidad de las sentencias de primera y segunda instancia sobre, Homicidio Culposo según los parámetros normativos, doctrinarios y jurisprudenciales pertinentes, en el expediente N° 00194-2010-0206JR-PE-01 del Distrito Judicial de Ancash 2017. Es de tipo, cuantitativo cualitativo, nivel exploratorio descriptivo, y diseño no experimental, retrospectivo y transversal. La recolección de datos se realizó, de un expediente seleccionado mediante muestreo por conveniencia, utilizando las técnicas de la observación, y el análisis de contenido, y una lista de cotejo, validado mediante juicio de expertos.
