Ruiz, Iván | 2019-06-29

Several technologies in electronics and informatics have been merged into medicine field. It is commonly called telemedicine. Specifically, this work proposes to scenario and an environment which a specific protocol of physical rehabilitation process can be executed and applied to a patient by a healthcare specialist who are geographically distant one another. In this sense, a Service Oriented Architecture (SOA) was designed and analyzed, trying to ensure the right communication process. Colored Petri Nets was used as a formal modelling tool. Finally, a brief mathematical approach is shown aiming to validate the architecture specifications.

Analysis of harmonic distortion generated by PWM motor drives
...
Sousa Santos, Vladimir | 2017

This paper evaluates the harmonic distortion generated by PWM motor drives in an electrical industrial system of a wheat flour mill company. For this, a comparative study between two industrial circuits connected at the same point of common coupling with similar characteristics of load and transformers is presented. The difference is that one circuit has PWM motor drives and the other does not have them. In the study, a practical method based on the statistical characterization of the total harmonic distortion of voltage (THDV) and current (THDI), individual voltage distortion (IVD), individual current distortion (ICD) and K-Factor is applied. As result, it was observed that PWM motor drives generated harmonics voltage mainly of fifth and seventh order with values that exceed limits established by standards in both circuits. In the work is also demonstrated that in the analysis of harmonics is necessary to consider various parameters and not only one.

Application of a central design composed of surface of response for the determination of the flatness in the steel sheets of a Colombian steel
...
Parody, Alexander | 2018

In this paper the results of research are shown in which the response surface was applied with central composite design for estimating the values of flatness as shown and accepted by the quality department and production company of the Caribbean region, taking into account factors such as voltage control in the winding sheet and the coefficient of friction. Initially, a first-order model was proposed to estimate the variance of the error and consider a quantitative model that takes into account the effects of combination. The method of steepest descent is used to sequentially move the descent path, i.e., in the direction of the minimum response decrement, until a new interval near optimal experimentation. Subsequently, a model of higher order was developed using a central composite design with center points and stars, taking into account control other variables additional response flatness, such as the roughness and hardness of the sheets in a range of flexible and acceptable tolerances for the company through a canonical model, and that will be the focus of future research.

Parody, Alexander | 2018

The inherent need to optimize production processes allows the generation of new knowledge that allows companies to achieve new horizons in terms of efficient management of productive resources, this study allowed to achieve a new advance in the efficiency of the pre-painting process, where the search focused on the maximization of the hardness of the paint on the metallic surface and the minimization of the percentage of solids in the paint, and by means of the application of a D-Optimo experimental design based on restrictions, it was determined that the Process variables: Monomer, Interlacer and Resin have a statistically significant relationship both with the hardness of the paint layer and with the percentage of solids in the paint. The optimum hardness values achieved are above the restriction imposed by the company to maintain the Knoop hardness value above 25, in the same way it was possible to achieve that the percentage of the solids found is below 30%, This being the minimum value desired by the leaders of the process.

Applying computer simulation modelling to minimizing appointment lead-time in elderly outpatient clinics: a case study
...
Ortiz Barrios, Miguel Angel | 2017

Appointment lead-time is a pivotal parameter in elderly outpatient clinics. In this regard, delayed medical care may represent complications in the elderly population and the development of more severe diseases. However, healthcare managers are not skilled in methods effectively reducing waiting times. Therefore, this paper presents the computer simulation modelling to tackle this problem. In this regard, the real-world system was initially simulated and then, three improvement scenarios were designed and validated operationally and financially. The results evidenced that Scenario 2 was the best choice since it provided a low investment per reduced day and a significant reduction (47.1%) regarding the probability of waiting for more than 8 days per appointment. With this proposal, the quality of medical care in elderly population can be meaningfully increased and decisionmaking process can be effectively supported

Architecture of an object-oriented modeling framework for human occupation
...
Balaguera, M. I. | 2018

The limitations of the actual theoretical structure of occupational science are discussed emphasizing on its implications when dealing with the stability and sustainability of social systems. By using a literature review focused on the time evolution and disciplinary distribution of the scientific production about human occupation, it is verified the insufficient production leading to the development of models that facilitate quantitative reasoning to support decision making. As an alternative, the architecture of an object-oriented framework is proposed. The framework is presented by using an UML (Unified Modeling Language) class diagram of a generic occupational system, including the class model of each system’s component: attributes and behaviors. Finally, guidelines are given for the use of the models produced with the framework in simulating diverse occupation systems scenarios.

Average reachability of continuous-time Markov jump linear systems and linear Markovian state observers
...
Narvaez Alfredo, Roa Rafael | 2018

Stability of state estimators for Markov jump linear systems featuring time-varying and correlated noise processes are studied in this paper. Three conditions for stability are presented, starting with a more general one requiring positiveness of the covariance of the error estimate, and is applicable to a class of filters that contains the well known linear minimum mean square estimators. It is then derived a more strict condition based on the plant parameters only, which may be interpreted as requiring that the state additive noise pervades every system dynamics. Finally, we consider a structural notion linked with the reachability gramian and we show it is a sufficient condition for the previous ones to be fulfilled, thus linking the filter stability with the structure of the plant, and present a simple rank test. Illustrative examples are included.

Por su parte Julia Elena Fortún plantea que «A pesar de ser una fiesta de carácter religioso dedicada a la Virgen del Socavón, a evocación de la Candelaria, cuya fiesta calendario es el dos de febrero, toda la festividad de la cual son los diablos los principales personajes, se la realiza indefectiblemente para carnaval.», en líneas posteriores complementa diciendo «es el espectáculo más grandioso del folklore boliviano. Todo un pueblo exteriorizando su fe mística en la perfección asombrosa de sus bailes, con cientos de bailarines diablos saltando uniformemente y sin descanso a través de las calles de la ciudad.». En otros casos, también se dice que esta fiesta “nació precisamente para honrar a la milagrosa Virgen de la Candelaria”. Son conocidos también los adjetivos que definen a esta festividad como a la “fastuosa entrada del carnaval”, desfile folklórico, procesión religiosa folklórica “el gran antruejo de los Andes”, etc.

Jacamanijoy - Jacanamijoy, Carlos | 2013

“En el tiempo primigenio toda la tierra estuvo a oscuras. Ya estaba poblado de todos los seres incluyendo el hombre. Pero este carecía de inteligencia y erraba a tientas buscando alimentos; realizando esta tarea los hombres, se tropezaron con el bejuco del yagé, lo partieron justo por la mitad y le dieron a probar a las mujeres y ellas quedaron extasiadas y tuvieron la menstruación. Cuando ellos lo probaron vieron extasiados cómo el pedazo que les sobró empezó a crecer y a trepar hacia el cielo. Poco a poco las sombras tomaron contornos y las siluetas empezaron a dar pequeños destellos y vieron que el yagé penetraba una flor inmensa que al ser fecundada se transformó en el Sol. De allí bajaron los hijos del sol, cada uno tocando una melodía distinta con sus flautas y tambores y cada melodía se transformó en un color distinto. Cuando llegaron a la tierra se dispersaron y cada uno depositó la luz y el color en cada ser y cuando el mundo estuvo totalmente iluminado toda la sinfonía de colores y música hizo brotar el entendimiento entre todos los hombres, creándose así la inteligencia y el lenguaje”.

Quiroz Malca, Haydée | 2013

El carnaval es tal vez una de las fiestas populares de mayor difusión en México; a pesar de que el carnaval se festeja en casi la totalidad de los estados de la República, la mayor parte de las veces, se desconoce el sentido de la repetición de las acciones y ritos que se generan durante su desarrollo. Aunque existe una larga discusión relacionada con el origen del carnaval, se identifica a la Edad Media como la etapa a la que solemos recurrir como el antecedente más inmediato en la historia. Esta costumbre arraigada, obviamente en España, llega a América durante la época colonial donde se mezcla con las viejas tradiciones prehispánicas, tomando características propias en cada grupo étnico y más adelante, en las ciudades y comunidades mestizas.

Sierra Domínguez, Julio | 2013

La historia cultural de nuestros pueblos tiene renglones que expresan el trayecto del carnaval en sus distintos matices. En ese trayecto se involucran elementos culturales populares generados para enriquecer el contexto del carnaval; sin embargo, ese mismo contexto ha sufrido contaminaciones que amenazan su esencia. Por tanto, vale la pena seguir pensando el carnaval; es la única manera de saber qué es lo que realmente hacemos, qué hemos logrado y en qué nos hemos equivocado. De esta manera, nace una crítica objetiva digna de consideración y respeto con derroteros cercanos al querer de los pueblos, sin que ello sea contrario al fundamento de identidad y pertenencia cultural de esos mismos pueblos.
