Resumen: Los procesos y la gestión de recursos son importantes discusiones actuales relacionadas con la toma de decisiones en el campo industrial. Este hecho motiva a las empresas a buscar modelos de gestión para mejorar sus procesos y servicios de forma continua. Con el fin de lograr este propósito, enfoques tales como la gestión de procesos de negocio (BPM) y el Costeo Basado en el Tiempo invertido por Actividad (TDABC) se utilizan como bases para el diseño de modelos. Este artículo describe el proc...

Resumen: The use of online social networks has expanded massively, they represent the way of communication of different types of users. However, the usability considerations in social networks when older people use them, have not been taken into account appropriately. Therefore, there are solutions focused on creating specific social networks for this target, but they do not consider special usability needs oriented to older people. This paper proposes a usability model for supporting the creation and...

Resumen: This paper presents preliminary results on evaluating the NeuroSky Mindwave headset for upper body motion intention classification. An artificial neural network (ANN) is trained by using a data set built for two different feature extraction methods, one based on the wavelet transform (WT) and another based on the use of spectrograms. Since there are five different types of brain waves,(α, β, γ, Δ, θ) some data aggregation procedures are proposed to reduce the dimensionality of the data s...

Resumen: Páramo soils store high amounts of organic carbon. However, the effects of climate change and changes in land cover and use (LC/LU) in this high-elevation tropical ecosystem may cause a decrease in their carbon storage capacity. Therefore, better understanding of the factors influencing the Páramo soils' carbon storage and export is urgently needed. To fill this knowledge gap, we investigated the differences in dissolved organic carbon (DOC) content in the soil water of four LC/LU types (tu...

Resumen: This article presents a hydrometeorological dataset from a network of paired instrumented catchments, obtained by participatory monitoring through a partnership of academic and non-governmental institutions. The network consists of 28 headwater catchments (<20 km^2) covering three major biomes in 9 locations of the tropical Andes. The data consist of precipitation event records at 0.254 mm resolution or finer, water level and streamflow time series at 5 min intervals, data aggregations at hou...

Resumen: Intelligent User Interfaces (IUI) facilitate human-machine interaction, through which the user makes use of a general system in a more efficient way. These interfaces are helpful for different types of users, specifically for people with disabilities, seniors, among others. These interfaces belong to a type of intelligent systems that are capable of self-adapt to users with different health problems, this is possible through the determination of behavior characteristics that distinguishes eac...

Resumen: The aim of Ambient Assisted Living (AAL) is to help people (e.g., elderly, children) to have an independent and monitored life with the use and assistance of technology. For this population, specific technologies have been developed; many of those technologies (i.e., hardware, software) use sensors and embedded systems. Although there are many studies that address AAL approaches, no systematic literature reviews have been presented that cover hardware and software working together and take in...

Resumen: In the XXI century, electronic commerce is considered as an alternative to reduce costs, increase the productivity, among other benefits, all of them perceived through the digitization of billing. Although there is a large amount of literature on this field, such literature is not focused on electronic invoicing platforms with notification delivery. Thus, the present systematic literature review has been performed, it is based on a reliable, auditable and rigorous methodology in order to know...

Resumen: This paper presents a stochastic scenario-based approach to finding an efficient plan for the electrical power distribution systems. In this paper the stochasticity for the distribution system expansion planning (DSEP) problem refers to the loads and wind speed behavior. The proposed DSEP model consist the expansion and/or construction of new substations, installation of new primary feeders and/or reinforcement the existing, installation of wind-distributed generation based, reconfiguration o...

Resumen: This research presents a simple mapping methodology for gait biomechanics of a human being into joint angles of a 10 degrees of freedom (DOF) biped robot. The joint angles are mapped by considering the zero moment point (ZMP) criterion. The walking control of the robot is performed by an optimal state feedback controller. The walking trajectories are planned in the sagittal plane, and they are generated in compliance with the ZMP of the robot - keeping the robot within the support polygon - b...

Resumen: A primitive relay channel (PRC) has one source (S) communicating a message to one destination (D) with the help of a relay (R). The link between R and D is considered to be noiseless, of finite capacity, and parallel to the link between S and (R,D). Prior work has established, for any fixed number of channel uses, the minimal R-D link rate needed so that the overall S-D message rate equals the zero-error single-input multiple output outer bound (Problem 1). The zero-error relaying scheme was ...

Resumen: Recently, Unmanned Aerial Vehicles (UAVs) have become a cheap alternative to sense pollution values in a certain area due to their flexibility and ability to carry small sensing units. In a previous work, we proposed a solution, called Pollution-driven UAV Control (PdUC), to allow UAVs to autonomously trace pollutant sources, and monitor air quality in the surrounding area. However, despite operational, we found that the proposed solution consumed excessive time, especially when considering t...
