Proyecto 3d + Realidad aumentada - Virgilio, Victor; Padilla, Julia; Jimenez, Salustino; Martin, Mario
In recent years augmented reality has evolved from an emerging technology to be one of
the trends in interactive design more attractive today. Artists, designers and a lot of people
with little programming experience can create their applications using various tools like
Processing, Blender, Arduino, Flash and many others. (Mullen, 2012) This technology is
already in many areas such as the reconstruction of the historical, the training of operators
of industrial processes, marketing, interior design, museum guides and of course academia.
(Rogo25, 2011) In this paper, augmented reality played an important role in the field of 3D
animation at the Technological University of the Usumacinta and achievement...

Prototipo itinerante de un sistema fotovoltaico para casa habitación, aislada de la red - Chávez, Rufino; García, Rufino; Olivo, Marco; Rodríguez, Juan
When we think of solar energy, are two manifestations of light and heat, are easily
recognized. Both play a vital role in the life of our planet. The sunlight makes possible the
process of photosynthesis, without which the plant and animal kingdoms disappear, climate
controlled heat and evaporates the waters of the sea, which, free from salt content, are
returned to the earth as rain. Humans, animals and plants owe their existence to this simple
mechanism purification. Solar radiation can be converted directly into electrical energy.
This phenomenon is called the photovoltaic effect. A mid-nineteenth century (1839)
French physicist Becquerel discovered the photovoltaic effect (PV). Several physicists...

Propuesta de una guía de validación para la determinación de sólidos suspendidos totales en aguas residuales - Uribe, Melina; Uribe, Sheila; Acosta, Jorge
The validation of analytical methods is of great importance for testing laboratories
wastewater want to ensure the quality and reliability of its results. In this paper we conducted
a validation guide for the determination of Total Suspended Solids (TSS) in wastewater. This
will set the parameters for limit of quantification, linearity, working range, recovery, bias
and precision (repeatability). As a result of the work is concluded, this guide will enable
testing laboratories develop each of the parameters to assess and meet the acceptance criteria
in determining TSS. It also serves as a source of information for other testing laboratories
(clinical, food, microbiological research centers, etc.) who wish...

Anaerobic digestion is a process proposed for treatment of urban wastewater effluent, in this
last, products like biogas and compost are obtained. Compost has been used in the biofertilizer
production. The integration of anaerobic digestion and composting treatments allow
giving to the wastes an energetic valorization and also using the nutrients for raise the
amount of them in the compost produced. Two bio-reactors with a volume of 200 L each one
was made. Physicochemical characteristics of the effluent were determined either into inflow
and outflow. A decrease in parameters such as COD and solids were analyzed. The gas
analysis showed an important amount of methane in the...
Perspectiva del uso de energía eléctrica mediante redes neuronales - Rojas, José; Luna, Ricardo
Demand for electricity in industrial, commercial and residential sectors represents a current
problem to predict ahead of time electricity consumption in these sectors in order to avoid
penalties imposed by the respective companies supplying electricity, plans to develop a
system perspective electricity demand for intelligent buildings using artificial neural
networks (ANN) that allows us a prediction of power consumption ahead of time, and
therefore better management of energy in buildings. The variables used as inputs to the
neural prediction model were: temperature and humidity, as well as power consumption and
time. The algorithm used for perspective was Levenberg-Marquardt. The model validation
was performed by comparing the results with...

Obtención empírica y no empírica de un conjunto específico de heurísticas sobre experiencia de usuario para sistemas de información - López, José; Hernández, Jorge; Rangel, Nelson; Rodríguez, Mario; Butron, Martha; Jasso, Omar
The set of ten heuristics proposed by J. Nielsen is oriented to measure the user experience
(UX) in general. However, when dealing with the particular case of an information system
(IS), these heuristics cannot identify all the bad situations, or problems, related with the
UX. This paper proposes the inclusion of three heuristics (identity, accessibility, y
attractivity) to those proposed by J. Nielsen, in order to identify better the problems about
by the UX in IS. The new set of heuristics was tested over a case of study composed by 54
ISs, 141 users of them, and a questionnaire applied to the users. Based on Usability
