This work presents the kinematic and dynamic modeling of a humanwheelchair system where it is considered that its mass center is not located at the wheels’ axis center of the wheelchair. Furthermore, it is presents a new motion controller for human-wheelchair system that is capable of performing positioning and path-following tasks. The proposed controller has the advantage of simultaneously performing the approximation of the robot to the proposed path by the shortest route and limiting its velocity. This controller design is based on two cascaded subsystems: a kinematic controller with command saturation, and a dynamic controller that compensates the dynamics of the robot. © Springer International Publishing Switzerland 2015.

Subía Arellano A.F.
;
Calvo Rodríguez M.M.
This qualitative work aimed to understand the social construction of violence in adolescents victims of trafficking for criminal purposes. Four life histories were made, which were analyzed through the dialectical hermeneutic method. The results show three main categories related to social history, family history and personal history. Adolescents have been participants in a violent social and family context, child labor, family violence, socioeconomic precariousness and gender violence, so that the social construction of violence is a determining factor in vulnerability to trafficking. © 2017, Universidad del Zulia.

The research develops an industrial software application called FAPS System for the planning and scheduling manufacturing. It contains three modules used for planning and programming of resources, process management and Andon module focused on the use of lean manufacturing techniques for the notification, emission and display of contingencies presented during the production in real time. A case study is described in Ecuadorian footwear companies for the execution of experimental prototype efficiency tests. Through the unified modeling language diagrams, the requirements and functionalities of the software developed based on private and free technologies are defined. The planning module has a scheduling algorithm of days based on weighted standards that allows to estimate the delivery date of a production order, reprogram it and compare the planned quantity with respect to the capacity used. The Andon module is an Android application that consumes the information managed in the planning and process modules, thereby monitoring in real time the state of the plant and the production progress. The experimental results show that the system is adaptable to multiproduct orders and the scheduling allows to increase 6% the utilization percentage of the production processes.

Ecuador, a privileged Latin American country recognized for its abundant natural resources and its rich cultural heritage, located in the four natural regions: Coast, Sierra, Oriente and the Insular Region. In this sense, according to the Ministry of the Environment, eleven territories met the requirements to achieve the denomination of National Parks; Llanganates was incorporated in 1996. The objective of this work was the landscape analysis by surveying the natural, anthropic and cultural elements of the Llanganates National Park; the applied methodology was based on a multidisciplinary model, through exploratory, descriptive and explanatory research, the qualitative approach linked to the assessment of landscape components. In addition, the intangible resources constituted by rich legends that emerged with the Spanish conquest, such as the capture and murder in Cajamarca of the Inca Atahualpa, transferred to Quito, and later buried according to expert historians and anthropologists, in the Hacienda Malqui Machay, Sigchos, province from Cotopaxi, a place rich in ruins and multiple Inca vestiges. It is also related that Rumiñahui, half brother and general of the Inca, moved the treasures and hid them in Llanganates, which aroused curiosity and expectation. Finally, the results obtained in the survey of the Biophysical, visual and anthropic components in addition to the cultural legacy are important to expose the great landscape values of the study site. In conclusion, the knowledge and enhancement of iconic places opened a broader perception of the mythical Llanganates National Park. © The author; licensee Universidad de la Costa - CUC.

Differential tolerance to increasing heterospecific pollen deposition in two sympatric species of Burmeistera (Campanulaceae: Lobelioideae)

Premise of research. Heterospecific pollen deposition on stigmas can impact plant reproduction by decreasing seed set or inducing fruit abortion. Pollinating bats often carry pollen from many species on their fur, and thus bat-pollinated flowers may exhibit tolerance to heterospecific pollen deposition, but to our knowledge this has never been studied. We investigated the relative impact of increasing heterospecific pollen deposition on female reproduction of two sympatric species of Burmeistera that experience pollen transfer between them by their shared bat pollinators. Methodology. We simulated heterospecific pollen deposition by applying pollen mixtures that differed in the ratio of heterospecific to conspecific flowers used to make them (3∶1; 2∶2, and 1∶3) and measured female reproduction by quantifying fruit abortion, seed number, and seed mass. Pivotal results. For Burmeistera borjensis, applying a higher relative amount of heterospecific pollen led to decreased seed production and lighter seed mass, whereas no significant effect of increasing heterospecific pollen was detected in Burmeistera ceratocarpa. Burmeistera borjensis aborted more fruits than B. ceratocarpa (44.1% vs. 18.8%); however, in both species the probability of fruit abortion was not affected by pollination treatment. Conclusions. We detected asymmetric impacts on female reproduction between this pair of sympatric Burmeistera: while increasing heterospecific pollen deposition decreased seed production and seed mass for B. borjensis, it had no detectable effect on B. ceratocarpa. Prior work shows that in nature B. borjensis receives much lower amounts of heterospecific pollen than B. ceratocarpa, and thus results suggest that B. ceratocarpa may have stronger gametic or postzygotic isolating barriers to be able to tolerate heterospecific pollen deposition. Future work should explore how different isolation mechanisms contribute to the asymmetric effects on female reproduction that we report here and whether tolerance to heterospecific pollen deposition is a common response among bat-pollinated plants and other plant taxa relying on low-fidelity pollinators. © 2019 by The University of Chicago.

Corporate veil in the execution of the labor obligationsthe [El velo societario en la ejecución de obligaciones laborales]
(2021)
Holguin E.P.H.
;
Lascano A.M.P.
The doctrine of the lifting of the corporate veil was created precisely to prevent abuses in the use of legal status, and consti-tutes a way that allows creditors to penetrate the patrimony of the partner or shareholder. The objective of this research is: To establish a reflective, critical and legal analysis of the legislation applicable to the lifting of the corporate veil for the execution of work-related sentences in Ecuador. The methodology that was applied was Historical-Legal-descriptive, because it allowed the historical monitoring of the subject of study and through the application of the analytical method. An important fin-ding of this work has been the analysis of cases, where the rights of workers, despite being recognized under a court ruling, cannot be fully enforced, due to having preceded fraudulent maneuvers by members of the legal entity that have simulated legal acts, to hide the assets of the companies and leave the workers unprotected. As a conclusion of the breaking of the hermeticism of the legal entity, it seeks to protect the rights of creditors, with the application of procedural actions regulated by law, and to link unpaid obligations to the assets of natural persons behind the corporate facade. © 2021, University of Cienfuegos, Carlos Rafael Rodriguez.

Surveillance Routing of COVID-19 Infection Spread Using an Intelligent Infectious Diseases Algorithm
(2020)
Guevara Maldonado, César Byron
;
Penas M.S.
In this study, the Intelligent Infectious Diseases Algorithm (IIDA) has been developed to locate the sources of infection and survival rate of coronavirus disease 2019 (COVID-19), in order to propose health care routes for population affected by COVID-19. The main goal of this computational algorithm is to reduce the spread of the virus and decrease the number of infected people. To do so, health care routes are generated according to the priority of certain population groups. The algorithm was applied to New York state data. Based on infection rates and reported deaths, hot spots were determined by applying the kernel density estimation (KDE) to the groups that have been previously obtained using a clustering algorithm together with the elbow method. For each cluster, the survival rate - the key information to prioritize medical care - was determined using the proportional hazards model. Finally, ant colony optimization (ACO) and the traveling salesman problem (TSP) optimization algorithms were applied to identify the optimal route to the closest hospital. The results obtained efficiently covered the points with the highest concentration of COVID-19 cases. In this way, its spread can be prevented and health resources optimized. © 2013 IEEE.

Santos M.
Citizen security is one of the main objectives of any government worldwide. Security entities make multiple efforts to apply the latest technologies in order to prevent any type of criminal offence. The analysis of a database of the National Police of Ecuador has allowed us generating patrol routes to prevent and reduce the crime rate in the city of Quito, Ecuador. The K-means clustering has been used to determine the points of greatest crime concentration and then linear regression is applied for the prediction of crimes within subgroups of data. Those way-points will allow to generate and optimize police patrol routes. The results obtained in the prediction of crimes is greater than 80%. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

Dynamics of a Unicycle-Type Wheeled Mobile Manipulator Robot
(2020)
Varela Aldas, José
;
Chicaiza, F.A.
;
Andaluz V.H.
Mathematical modeling is widely used in robotics to display behaviors and design control algorithms; the dynamic model of a robot describes the movements considering the action of internal and external forces of the system. This paper presents the dynamics of a unicycle mobile manipulator robot using the Euler-Lagrange proposal and conditioning the model to obtain the output velocities in the robot from the desired velocities. Additionally, the dynamic model is complemented by the identification of parameters using experimental data obtained from the AKASHA robot. The results present the signals applied in the identification, the values of the dynamic constants are found and the validation data which indicate a correct performance of the proposal are graphically shown. © 2020, Springer Nature Switzerland AG.
