Executable Model Development from Architectural Description with Application to the Time Sensitive Target Problem

As the Department of Defense (DoD) moves to a capabilities-based approach for requirements definition and systems development, it has become necessary to conceptualize and evaluate our needs at the System of Systems (SoS) level. Desired capabilities are often achievable only through seamless integration of many different systems. As the classical systems engineering approaches are not suited to effectively handle the complexity of SoS level concepts, an architectures-driven approach has emerged as a way of defining and evaluating these new concepts. While the use of architectures for documenting and tracking interfaces and interoperability concerns is generally understood, architectural analysis and the use of executable models for evaluation of architectures remain an open area of research. With this purpose in mind, this thesis will apply architectural-based analysis to the proposed Time Sensitive Effect Operation (TSEO2012) scenario. This scenario will become the baseline for architectural analysis, and an excursion to this baseline will add a Weapon Born Battle Damage Assessment (WBBDA) capability. By creating an executable model, the two architectural concepts can be compared against each other. The addition of a WBBDA capability to the TSEO architecture improves the efficiency of the time sensitive target operations by shortening the decision cycle for target re-strike. While this effort was successful in obtaining an executable model directly from the architecture description, it highlighted the importance of having sufficient and correct information contained in the architecture products

Strategic Asset Allocation in a Continuous-Time VAR Model

This note derives an approximate solution to a continuous-time intertemporal portfolio and consumption choice problem. The problem is the continuous-time equivalent of the discrete-time problem studied by Campbell and Viceira (1999), in which the expected excess return on a risky asset follows an AR(1)process, while the riskless interest rate is constant. The note also shows how to obtain continuous-time parameters that are consistent with discrete-time econometric estimates. The continuous-time solution is numerically close to that of Campbell and Viceira and has the property that conservative long-term investors have a large positive intertemporal hedging demand for stocks.

Development of a novel equine influenza virus live-attenuated vaccine

H3N8 equine influenza virus (EIV) is an important and significant respiratory pathogen of horses. EIV is enzootic in Europe and North America, mainly due to the suboptimal efficacy of current vaccines. We describe, for the first time, the generation of a temperature sensitive (ts) H3N8 EIV live-attenuated influenza vaccine (LAIV) using reverse-genetics approaches. Our EIV LAIV was attenuated (att) in vivo and able to induce, upon a single intranasal administration, protection against H3N8 EIV wild-type (WT) challenge in both a mouse model and the natural host, the horse. Notably, since our EIV LAIV was generated using reverse genetics, the vaccine can be easily updated against drifting or emerging strains of EIV using the safety backbone of our EIV LAIV as master donor virus (MDV). These results demonstrate the feasibility of implementing a novel EIV LAIV approach for the prevention and control of currently circulating H3N8 EIVs in horse populations

MEMORIAS | electronic literature + live coding performance

Memorias is a web-based artistic project by Jessica Rodríguez developed through the Estuary platform —an online platform to host live coding languages. It is based in six autobiographical writings connected to the way she “hears”, “writes”, “watches”, “reads”, “sees” and “listens” to the word. Through these texts, six code works were designed and programmed, hybridizing natural and computing languages by parsing three existing live coding languages: Tidal Cycles, Punctual, and CineCer0. Together, Memorias’ languages collide different materialities as well as visual and sonic approaches, going from voices in English, Spanish, Cello and Paetzold samples, audio and visual synthesis, and pre-recorded video clips. This project explores how speech and literature — in its written form— can be used as interfaces that allow the performer to communicate both, with the computer and the audience. Additionally, speech —in its sonic form— is moved through space and time, expanding the possibilities of spoken literature by producing unlimited variations of the “original” autobiographical writings. Within the space/time of the piece, the audience can experience different ways, textures and logics to approach visual and sound through the use of language as a memory trigger. For this conference, Memorias is be presented as an online collaborative performance by andamio.in, including Jessica Rodríguez, Rolando Rodríguez, Alejandro Brianza, and Luis M. Zirate.

Procesamiento intraoracional de pronombres personales en ninos con trastorno especifico del lenguaje

62 p.Los niños con trastorno específico del lenguaje (TEL) suelen presentar dificultades a nivel de la morfosintaxis. Entre otros aspectos, manifiestan problemas en el procesamiento de los pronombres. El presente estudio está dirigido a estudiar este aspecto en niños con TEL a través de la aplicación del Test de Referencia Pronominal Sintáctica. Estudios previos sobre este tema en el habla inglesa utilizando esta misma prueba indican que los niños con TEL presentan un desempeño inferior en el procesamiento de los pronombres personales que sus controles. El propósito de este estudio fue conocer el rendimiento de los niños con TEL de lengua española en el procesamiento de pronombres personales. Los resultados obtenidos sugieren que los niños con TEL de habla española también presentan un rendimiento inferior en el procesamiento intraoracional de pronombres personales, lo que se podría relacionar con un déficit representacional para las relaciones de dependencia sintáctica
