Analysis of the start to the first hurdle in 110m hurdles at the IAAF World Athletics Championships Beijing 2015
The purpose of this study was to use observational analysis to evaluate the relationships between variables
measured at the start of the men’s 110 hurdles event and race performance itself. Data were obtained for
competitors in 2015 IAAF World Athletics Ch
ampionships, in Beijing, China. The athletes’ start was quantified
by reaction time and time to the first hurdle; their action over the first hurdle was quantified by the take
-
off
distance (i.e., the distance from the last step to the first hurdle), the la
nding distance, and the total distance
in the air over the first hurdle. Regression analyses revealed that the combination of one measure of the start
(either reaction time or time to the first hurdle) and the measure of propulsion over the first hurdle (d
istance
in air over the first hurdle) predicted performance (SEE = 0.23 s in the heats, SEE = 0.16 s in the semi
-
finals,
SEE = 0.09 s in the finals). In addition, looking at performances in the finals, where all athletes with available
data used a seven
-
st
ep approach to the first hurdle, inclusion of stride length data improved the prediction
somewhat (SEE = 0.07 s). The results demonstrate that a combination of a fast start, rapid acceleration, and
strong drive over the first hurdle quantifiably explains a
nd contributes to performance in the men’s 110 m hurdles at the highest level

Servidor web multiplataforma con implementación CGI
El objetivo que perseguimos en este trabajo fue el desarrollo de un servidor Web multiplataforma basado en el protocolo HTTP 1.0 con implementación de la interfaz CGI, utilizando como lenguaje de programación JAVA. Los métodos que implementa son GET, HEAD, POST, PUT, DELETE .También dotamos al servidor con la capacidad de entender y responder a peticiones de clientes que utilicen protocolo HTTP 0.9 (GET) y HTTP 1.1 (GET, HEAD, POST, PUT, DELETE, OPTIONS, TRACE).
Desarrollamos también un administrador del servidor que permitiera, a la persona que lo administrara, decidir dónde se encontrarÃan los recursos que podrÃan ser accedidos a través del servidor y si éstos serÃan de libre acceso o de acceso restringido; todo esto a través de una interfaz gráfica.
Y como complemento, decidimos construir un cliente web que permitiera subir (upload) y bajar (download) archivos en un servidor y otros métodos que navegadores comerciales no implementaban.Eje: Sistemas operativosRed de Universidades con Carreras en Informática (RedUNCI
MetodologÃa para el modelado y el análisis de flujos IP multimedia: Medidas de calidad
El presente trabajo propone una metodologÃa para el modelado y el análisis de flujos IP multimedia que se transportan mediante tecnologÃas WiFi. Dicha metodologÃa tiene como objetivo la obtención de modelos de tráfico multimedia de manera experimental y generación de tráfico en entornos controlados de laboratorio para una aproximada reconstrucción de los escenarios reales. Además, se propone la adaptación de todo el proceso a otros tipos de tráfico y la automatización de los mismos. En primer lugar, para la realización del trabajo se describen algunas de las herramientas más utilizadas, y otras más recientes, que permiten la captura de datos, la gestión y generación de tráfico, asà como el procesado de la información. También se describen una serie de aplicaciones reales escogidas en el presente trabajo, que generan los flujos IP con requerimientos temporales entre los extremos de la comunicación (voz, vÃdeo y streaming). Por otro lado, dicha metodologÃa se pone a prueba para la construcción de modelos de flujos IP de voz y vÃdeo, obteniendo resultados que permiten generar el mismo tráfico sin la necesidad de la aplicación. También, se utiliza para modelar las caracterÃsticas del escenario. Como ejemplo se realiza el modelado de un buffer en un punto de acceso WiFi. En él se determinan algunas de sus caracterÃsticas técnicas y funcionales más relevantes. Con dichos flujos se realizan medidas de calidad en cuanto a pérdidas en entornos 802.11, en diferentes escenarios inhalámbricos reales. Estas medidas se comparan con los valores teóricos del protocolo de acceso al medio utilizado por dicho estándar CSMA/CA (Carrier Sense Multiple Access Collision Avoidance) para analizar el comportamiento real y encontrar las posibles diferencias. Al final se plantean las conclusiones obtenidas y algunas de las lÃneas futuras de investigación que se relacionan con los fenómenos observados

Water and Flamingo Feces Bacterial Communities from High- Altitude Andean Lakes under Selective Antibiotic Pressure Studied by PCR-DGGE Analyses
High-altitude Andean lakes are exposed to extreme environmental factors like high salinity, ultraviolet radiation, heavy metals, among others. As it was previously shown, these lakes are not only the habitat of a high diversity of bacteria with multiple resistances; they also support an enormous population of flamingos, which migrate among these wetlands, and they could play a role as disseminators and/or reservoirs of pathogenic bacteria
Proposal of an ISO/IEEE11073 platform for healthcare telemonitoring: plug-and-play solution with new use cases
Proceeding of: 29th Annual International Conference of IEEE Engineering in Medicine and Biology Society, (EMBS 2007), Lyon, France, 23-26th august 2007.Remote patient monitoring in e-Health is everyday closer to be a mature technology / service. However, there is still a lack of development in areas such as standardization of the sensor’s communication interface, integration into Electronic Healthcare Record systems or incorporation in ambient-intelligent scenarios. This work identifies a set of use cases involved in the personal monitoring scenario and highlights the related features and functionalities, as well as the integration and implementation difficulties found when these are to be implemented in a system based on the ISO/IEEE11073 (X73) standard. It is part of a cooperative research effort devoted to the development of an end-to-end standards-based telemonitoring solution. Standardization committees are working towards adapting the X73 standard to this emerging personal health devices market and use case identification is essential to direct these revisions.This research work has been partially supported by projects TSI2005-07068-C02-01 and TSI2004-04940-C02-01 from Ministerio de Educación y Ciencia (Spanish Government), and a personal grant to both M.Galarraga and M.

The neovolcanic axis is a barrier to gene flow among Aedes aegypti populations in Mexico that differ in vector competence for Dengue 2 virus.
The Neovolcanic axis (NVA) traverses Mexico at the 19th parallel and is considered to be a geographic barrier to many species. We have demonstrated that the intersection of the NVA with the coast in Veracruz state is a barrier to gene flow in Ae. aegypti. This was unexpected because the intersection of the NVA with the Pacific Coast is not a barrier to gene flow. Further studies to identify the actual mechanism(s) that is(are) contributing to the lack of gene flow will provide important information on the trafficking potential of Ae. aegypti, which will be of great value to Ae. aegypti control programs. There are significant differences in vector competence for dengue virus between mosquitoes north and south of the NVA, but the epidemiological significance of these finding remains to be determined. Future studies will determine if, for example, the genes that condition midgut infection and vector competence of Ae. aegypti populations provide biomarkers for risk of dengue transmission. Such biomarkers could be of great value to control programs in resource limited environments by allowing targeting of vector control efforts to areas at most risk for epidemic dengue and dengue hemorrhagic fever
INTEGRATION OF DYNAMIC INFORMATION ON ENERGY PARAMETERS IN HBIM MODELS
The conservation of cultural heritage can be affected by different changes in temperature and humidity within architectural spaces, so energy performance and interior microclimate of historic buildings require adaptation to new maintenance and prevention studies. The search for these new investigations brings cultural heritage closer to new digital technologies such as Historic Building Information Modelling (HBIM). In this work, a new interdisciplinary methodology is developed between energy operators and BIM operators, so that a new framework is created to monitor energy parameters through intelligent sensors that measure temperature and humidity in the fully interoperable and semantically enriched 3D model itself. The study's commitment involves solving the interoperability workflow between sensors and the BIM platform, taking advantage of this new interconnectivity. For the study, a methodology applied to the Church of the Sacred Heart of Jesus in Seville was carried out, where from a survey through a georeferenced terrestrial laser scanner with topographic equipment, it is modelled from the point cloud, incorporating the sensors in the HBIM Project. In the workflow, it has been shown that the integration of microclimate data inside churches can be managed directly in the environment of an HBIM-based model and transfer a reverse flow in the process
