No full textArt and public space: a review from the Tijuana border
No full textArt in public space shows the complex relationshipbetween different profiles of artists, and between artistsand passer-by spectators, in terms of appropriation andsymbolization of cities, traversing issues such as identity,memory, and meanings through aesthetic representation. The purpose of this paper is to distinguish the different logics,discourses, and intentions behind artistic interventions inthe public space. To do this, it covers artistic actions, bothcontemporary art and street art, and also artivism, in the bordercity of Tijuana, Mexico, and analyzes the disputes over theoccupation of urban space through art, as well as the positionsin the face of social asymmetries of the city as a border city withthe United States. This journey is carried out historiographicallythrough the selection of images that account for the variousartistic manifestations analyzed. In addition to this, this workaims to provide a record as an archive, by selecting photographsof artistic pieces that have disappeared due to their public-urbannature.
Effects of default under the mexican National Code of Civil and Family Proceedings. Comparative analysis
No full textIn civil proceedings, a series of procedural burdens are imposed on the parties involved in the procedural legal relationship, so that each of them has the power to act and exercise the procedural rights that they possess. Thus, the defendant must file the answer to the claim within the term granted for such purpose in the summons to the trial. Now, the failure of the defendant to file an answer within the terms of the law generates the figure of default or contumacy which, in turn, produces a series of consequences of a procedural nature that are addressed in this work through the comparative study of different procedural codes of various federal states, the federal legislation, and the text of the recently published National Code, and the text of the recently published National Code of Civil and Family Procedures to identify the effects, as well as the similarities and differences between them, in addition to a doctrinal analysis of this legal figure that goes from the general to the particular, which, as a whole, allows to sustain the need to modify the normative text, even before its application
Applied multicriteria methodology under Pythagorean fuzzy environment with FMEA to appraise new product development process.
No full textNew Product Development Process (NPDP) is an important process in the industry, since it helps the global companies to get the expected sales and revenues, because of the launch of new products into the market. Moreover, NPDP is a complex process while requires the involvement of multiple functional areas, where people must be synchronized to execute the project activities, during this long process, different risks appear and can affect the project results, delaying the project launch introducing new products with unexpected defects for customers, reason why the global companies are continuously looking for NPDP improvements, trying to enhance the NPDP risk assessment.
This thesis presents the use of Pythagorean fuzzy sets, Dimensional Analysis, Failure Mode and Effect Analysis, and Value Stream Mapping (PFDA-FMEA-VSM), method that have the main objective to disperse the uncertainty during the NPDP risk assessment.
Concluding this investigation, it is demonstrated that PFDA-FMEA-VSM is enhancing NPDP making possible to get a strongest NPDP appraisal, while allows to have a clear view of the real risks thru all the NPDP process steps, helping the project stakeholders to take best decisions for the business. The conclusion is as well supported by results published at different pear reviewed scientific journals
Metodología de teleoperación robótica con realidad aumentada para generación de trayectorias de reparación en un ambiente con microgravedad y oclusión visual.
No full textLas misiones robóticas teleoperadas en órbita son comunes para reparar o mejorar estaciones de investigación, comunicación u observación en el espacio. En las misiones de teleoperación, las regiones de interés o componentes a ser atendidos pueden quedar ocluidos por la luz o por un obstáculo físico, lo que dificulta la maniobra teleoperada, y compromete el éxito y la seguridad de la misión. En ocasiones puede ocurrir una colisión no deseada debido a los puntos ciegos generados por la oclusión. En el presente documento se muestra una metodología de teleoperación con presencia directa y Realidad Aumentada (AR por sus siglas en inglés) que le permite a un robot remoto realizar una trayectoria en órbita a pesar de la presencia de áreas visualmente ocluidas, debido a que le permite al operador en el ambiente local obtener una perspectiva libre de oclusión visual en un entorno 3D (tridimensional) modelado dinámicamente. Además, para que el efector final del robot espacial reproduzca con precisión el movimiento natural de la mano de un operador humano, se utiliza un dispositivo de presencia de mano directa para mapear directamente los movimientos relativos de la mano del usuario a los movimientos relativos del efector final (EF) del robot. El sistema se valida en un entorno AR con entidades virtuales y físicas para realizar una reparación de un panel solar de un satélite objetivo en un área ocluida visualmente para el sistema de visión del robot. Los resultados experimentales muestran que debido a que el entorno virtual se puede manipular en tiempo real para obtener una perspectiva sin oclusión visual, el operador humano puede generar una trayectoria en el ambiente remoto sin comprometer la integridad del robot, a pesar de que el EF del robot y el sistema de visión no tienen la propiedad de observar directamente el área de interés. Actualmente, en el estado del arte no se ha reportado una solución generalizada para ejecutar una tarea en un área visualmente ocluida. Sin embargo, con la metodología propuesta, se comparó el sistema de presencia directa contra un joystick y un sistema MMK (Mouse-Monitor-Keyboard por sus siglas en inglés) en una tarea de teleoperación con un área visualmente ocluida y se reportó una mejora en el desempeño del 25% con respecto al MMK y 15% con respecto al joystick, en cuanto al tiempo promedio que toma a una persona alcanzar una región de interés
Estimación de frecuencia cardiaca por medio de la señal de voz.
No full textEl propósito de este trabajo es establecer un método para estimar la frecuencia cardiaca (FC) a través del habla humana pronunciando las vocales A, E, I, O, U, implementando el análisis de la señal de voz. Este se presenta como un método no invasivo para monitorear la actividad cardiaca con el propósito de detectar alteraciones relacionadas con una elevación o descenso de la frecuencia cardíaca de un individuo que pueden poner en riesgo su salud. Se realizaron experimentos para establecer la correlación de la estimación de la frecuencia cardiaca en dos condiciones de estado, uno pasivo donde se evalúa al sujeto en condiciones normales y una activa en el cual el sujeto realiza un breve ejercicio aplicado con el fin de incrementar la frecuencia cardiaca; se recolectaron datos de 30 sujetos de los cuales se tomaron 15 hombres y 15 mujeres. Se registraron 900 muestras de frecuencias cardiacas patrón obtenidas por medio del electrocardiograma de los sujetos de estudio utilizando un algoritmo en LabVIEW, y de igual manera se analizaron 900 muestras de señales de voz que fueron procesadas en un algoritmo desarrollado en MATLAB con la finalidad de determinar la correlación entre la señal de voz y la frecuencia cardiaca patrón. La señal de voz fue procesada a través de la transformada Wavelet continúa generando un escalograma que posteriormente sería analizado a lo largo del tiempo por medio de la transformada discreta de Fourier
Masculinity and public policies: the organization of an agenda in Mexico.
No full textThe main purpose of this communication is to identify, to describe the process of building a public policy agenda that involves men in the construction of equality with women, and to recognize the perception of those who participated in it. It conceived the process as an organization with its own dynamics. A descriptive research about ethnographic approach involved recovery of documentary information of the process, interviews with participants in the construction of the agenda and a workshop. Results are presented in a timeline involved papers to prepare work meetings; profiles of potential participants were identified, the work to be developed was outlined and the respective call for in-person and virtual meetings was issued. Participants in the work meetings discussed contents of the agenda and political impact, the requirements to continue the process and the formation of specialized working groups. Elements such as uncertainty, the breaking of agreements and their fixed, the (mis)knowledge of what public policy among others, intervened in the process. As a conclusion, the lessons that emerge from this process are noted
