Sometimes wireless sensors could be placed randomly without predetermined coordinates, so systems to self-locate in an area should studied. This paper shows two approaches developed by us where find their position using WLAN technology. The scenario is indoor environment that contains walls, interferences, multipath effect, humidity and temperature variations, etc., both are based on the Received Signal Strength Indicator (RSSI). first approach uses a training session Neuronal Networks...

Autonomous driving is undergoing huge developments nowadays. It expected that its implementation will bring many benefits. cars must deal with tasks at different levels. Although some of them are currently solved, and perception systems provide quite an accurate complete description the environment, high-level decisions hard to obtain in challenging scenarios. Moreover, they comply safety, reliability predictability requirements, road user acceptance, comfort specifications. This paper...

We present a method of modeling the basin attraction as three-dimensional function describing two-dimensional manifold on which dynamics system evolves from experimental time series data. Our is based density data set and uses numerical optimization tools. also show how to obtain analytic curves that describe both contours boundary basin. applied problem regaining balance after perturbation quiet vertical stance using an elite athlete. goes beyond statistical description data, providing...

With the growing demand of Intelligent Transportation Systems (ITS) for safer and more efficient transportation, research on development such vehicular communication systems have increased considerably in last years. The use wireless networks environments has grown exponentially. However, it is highly important to analyze radio propagation prior deployment a sensor network complex scenarios. In this work, wave characterization ISM 2.4 GHz 5 Wireless Sensor Networks (WSNs) deployed taking...

It is throughout childhood and adolescence that many behavior patterns which are going to have a powerful influence on health during adult life established. This study aimed at analysing the physical activity has of adolescents determining relationship thereof with blood pressure (BP) body composition.The research was conducted from November 2002 February 2003, using Modifiable Physical Activity Questionnaire for Adolescents, measures degree activity. The anthropometric variables were also...

Las fases de la carrera 100 m lisos se han identificado en funcion variables cuantitativas escasas ocasiones (Mackala, 2007; Saito, Nagahara, Ae & Matsuo, 2008). El objetivo principal este estudio fue proponer una herramienta calculo para identificar fase aceleracion velocidad instantanea (m·s-1) y comparar esta con inicial calculada a partir del tiempo apoyo (s) fuerza reaccion vertical maxima (N). Se analizaron las carreras completas cinco atletas varones elite nacional (25±5,76 anos)....

El concreto u hormigón es uno de los materiales más versátiles usados en la construcción. En actualidad, se usa extensivamente industria, ya que puede ser moldeado formas casi arbitrarias a través moldes rígidos denominados encofrados. La manera disponen distintos elementos para formar el encofrado y las restricciones asociadas, genera retos computacionales interesantes impactan directamente industria este artículo propone implementación un modelo encofrados muros rectilíneos usando...

The purpose of this study was to assess the increase Latino parents’ confidence in advocating and supporting their child’s schooling. intervention implemented six public independent school districts Southwest United States. data examined through matched pre- post-surveys (n = 45). Findings are consistent describing a successful program post-gains preparing families aid children becoming academically successful.

An analysis of the strut‐to‐fuselage and main‐landing‐gear‐to‐fuselage joint is realized in order to evaluate zones with a high probability failure. The whole section analyzed using finite element method estimate static resistance behavior, therefore it becomes necessary create numerical model section, measure mechanical properties C‐Ep composite material, calculate loads applied onto section. digitized photogrammetry. Mechanical characterization achieved instrumented standardized tensile...

With the growing demand of Intelligent Transportation Systems (ITS) for safer and more efficient transportation, research development such vehicular communication systems have increased considerably in last years. The use wireless networks has been extended an exponential environments. However, it is highly important to conduct previous radio propagation analysis when deploying a sensor network complex scenarios. In this work, wave characterization ISM 2.4GHz Wireless Sensor Networks (WSN)...
