This study presents key features to develop an efficient tele-rehabilitation platform to support the recovery process in patients after hip replacement surgery. The tool is designed on the concepts of therapeutic education and serious games, in order to enhance the self-rehabilitation. Also, the system is built on a modular architecture to ensure its scalability and adaptation to other physical therapeutic programs. The assessment module integrated in the platform and implemented in dynamic time warping allows for a fair discrimination of the quality of the exercises performed by the users, especially when the motion acquisition is not affected by occlusion. An important contribution of this work is to propose a method that can assess both the range of motion and the compensation movements that may be involved in each exercise.

The present work describes different methods or techniques of computer vision, used to estimate the level of fermentation of the cocoa bean. The description of several methods is performed, such as, vectorial quantification, K - means, fuzzy grouping and average displacement. Based on these methods, the training and classification phase of the images has been executed. A simulation platform is used to codify and execute the different methods, obtaining results with a level of certainty of approximately 75%. The images used in this research have been obtained directly during the process of fermentation of cocoa and the reference pattern for the level of fermentation has been developed with information provided by experts in sensory profiles, tasters of cocoa.

This paper presents the implementation of a facial-identity and -expression recognition mechanism that confirms or negates physical and/or computational actuations in an intelligent built-environment. Said mechanism is built via Google Brain’s TensorFlow (as regards facial identity recognition) and Google Cloud Platform’s Cloud Vision API (as regards facial gesture recognition); and it is integrated into the ongoing development of an intelligent built-environment framework, viz., Design-to-Robotic-Production & -Operation (D2RP&O), conceived at Delft University of Technology (TUD). The present work builds on the inherited technological ecosystem and technical functionality of the Design-to-Robotic-Operation (D2RO) component of said framework; and its implementation is validated via two scenarios (physical and computational). In the first scenario—and building on an inherited adaptive mechanism—if building-skin components perceive a rise in interior temperature levels, natural ventilation is promoted by increasing degrees of aperture. This measure is presently confirmed or negated by a corresponding facial expression on the part of the user in response to said reaction, which serves as an intuitive override / feedback mechanism to the intelligent building-skin mechanism’s decision-making process. In the second scenario—and building on another inherited mechanism—if an accidental fall is detected and the user remains consciously or unconsciously collapsed, a series of automated emergency notifications (e.g., SMS, email, etc.) are sent to family and/or care-takers by particular mechanisms in the intelligent built-environment. The precision of this measure and its execution are presently confirmed by (a) identity detection of the victim, and (b) recognition of a reflexive facial gesture of pain and/or displeasure. The work presented in this paper promotes a considered relationship between the architecture of the built-environment and the Information and Communication Technologies (ICTs) embedded and/or deployed.

Under a preamble of parallel robot platforms with a fixed base and a classic 6 DOF Stewart Gough Platform analysis, specifically on its application for flight simulators, this article contains the design and positioning simulation of a spatial disorientation simulator with the use of a modified Stewart Gough Platform, limited to 4 DOF which will restrict the ability of the upper platform for making linear x, y movements but will maintain its capability of taking any orientation and will also improve the entire system by adding a controlled and not restricted yaw rotation for recreating the accelerations produced in an aircraft during the flight in order to get the disorientation effect experienced by the pilots with physical illusions. Obtaining benefits in both, military and private training processes.

Electric vehicles are shifting the paradigm of electrical distribution networks operation. Thus, the operation of electrical distribution networks is becoming more complex and challenging for ensuring quality, security and reliability. In this paper, the plug-in electric vehicles charging coordination on electrical distribution networks is to carried out. The plug-in electric vehicles batteries equations are modeled and embedded into a charging coordination mixed-integer second-order cone programming model. The proposed mathematical model is formulated to minimize the total operational costs of the electrical distribution networks by determining an optimal charging coordination for the plug-in electric vehicles batteries. Results of a case study based on the 136-node test system show the effectiveness of the proposed approach.

To meet the academic objectives for courses related with Control Systems, it is important to have access to real educational platforms that help to extend the theory to a hands-on experience. This paper introduces the implementation of an experimental testbed used to control the orientation of a multirotor in an interactive fashion. The testbed is implemented based on the configuration of a quadcopter by restricting its ability to fly, but allowing it to rotate around its three main axes. The orientation model of a quadcopter is also presented focusing on the experimental estimation of the thrust and drag coefficients. A PID-based attitude controller is designed and discretized in order to implement it in an embedded system. Simulation results and initial experimental tests are included showing the response of the multi-rotor experimental testbed and the performance of the controller.

In this paper, we present a system for counting people on public transport. The system consists of a single camera, and it process videos obtained from the camcorder to perform an algorithm to identify and to count people using Artificial Neural Networks (ANNs). The system is implemented by Cpp language based on OpenCV. People counting is an important factor to guarantee safe road trips as transport vehicles must not exceed an established number of passengers. This research is aimed to create a technological tool that helps to comply with the Transit Law in Ecuador. We describe different processing blocks dedicated to the detection, segmentation, direction estimation, counting, and evaluation of images to present its results during the standard travel of a bus.

Chronic foot pain is a disease that progresses with age and has a high prevalence. Therapeutic procedures include the utilization of orthoses or insoles that are placed inside the footwear. Design of personalized insoles is a process that includes several stages. An important stage is the acquisition and analysis of footprint images. Their segmentation enables quantification of the footprint shape by estimating several indices that allow classification and diagnosis of foot morphology abnormalities. A segmentation method for footprint images using Level-Set algorithms is reported. Two area based Level-Set segmentation algorithms were applied. The first is the Chan-Vese algorithm using a global minimizer. The second is the Lankton algorithm that implements the Chan-Vese energy function using a localized minimizer and the Sparse Field Method for reducing the computational cost. Algorithms tested are accurate for segmenting the footprint images, providing an average Dice coefficient higher than 0.93. The Lankton algorithm is robust with respect to spatial variation in intensities within the footprint shape. It is also fast as the average time for segmenting one image is only 6.4 seconds.

This research is part of the development of a web platform, that allows home support in the recovery of a patient after a partial or total hip replacement operation known as arthroplasty. Currently, there is no support system for the patient to remotely perform the exercises for recovery. The application aims to reduce recovery costs as well as to provide access to health at a low cost. Therefore, it is important to have a web system accessible to all users. To achieve this parameter, and to determine if it provides information accessible to all, regardless of the physical capabilities of the users, the accessibility guidelines were applied in accordance with the Web Content Accessibility Guide (WCAG) 2.0 and Website Accessibility Evaluation Methodology 1.0. This study presents an evaluation of the website’s accessibility using automatic tools and an analysis to improve the accessibility of the platform providing elderly patients with an accessible and inclusive website. The preliminary results of our research show that the telerehabilitation platform requires improvements to comply with certain levels of web accessibility.
