As a result of the COVID-19 pandemic, the learning and evaluation processes have been moved to an online modality to keep social distance and reduce the spreading of the virus. The strategies implemented for assessment and proctoring in this online remote teaching and assessment emergency are no exception when proctoring test-takers. This problem i...

En la presente obra se describe la realización de un ejercicio de validación de resultados de una prueba psicológica aplicada a maestros y alumnos en estado de aislamiento por la pandemia por COVID-19 en el estado de Coahuila, México. El objetivo de este trabajo es aplicar técnicas de machine learning para validar un instrumento que mide las emocio...

This paper presents a hybrid grasshopper optimization algorithm using a novel decoder and local search to solve instances of the open vehicle routing problem with capacity and distance constraints. The algorithm’s decoder first defines the number of vehicles to be used and then it partitions the clients, assigning them to the available routes. The...

This paper presents a biased random-key genetic algorithm designed to solve the open vehicle routing problem with capacity and distance constraints. Consider a depot from which vehicles depart to deliver goods demanded by clients. Every client is served by one vehicle that is part of a homogeneous fleet. The vehicles initiate their routes at the de...

Report about the result of our BRKGA algorithm for the open vehcile routing problem

Frequently, people with dementia exhibit abnormal behaviors that may cause self-injury or burden their caregivers. Some audible manifestations of these problematic behaviors are of vocal nature (e.g., shouting, mumbling, or cursing), others are environmental sounds (e.g., tapping or slamming). The timely detection of these behaviors could enact non...

Residences for geriatric patients are usually understaffed, with each caregiver being in charge of several residents. A caregiver must assess the well being of residents and report to the medical staff if there is something unusual with a resident. Deviations from the routine will trigger an alarm, and automatic tools can help in making timely deci...

Visualization enables analytic reasoning supported by an interactive visual graphical interface designed to easily interpret and assess large amounts of data. In the health care domain, visualization might help in the decision-making process and could provide a clearer understanding of patient data. In this paper, two visualization tools are propos...

Geriatric residences are companies dedicated to provide care to older adults. Usually, the number of residents surpasses the number of caregivers producing that the caregivers are not fully aware about the state of the residents. We propose the design of a visualization tool with the purpose of depict useful and relevant information to caregivers a...

In federated query processing, different datasets can be queried simultaneously. Each dataset has different privacy policies attached, but, which privacy policy will govern the usage of the query result? In this work we propose a mechanism, based on semantic web technologies, to compose privacy policies. The originality of our approach is that our...

As the number of older adults increases, and with it the demand for dedicated care, geriatric residences face a shortage of caregivers, who themselves experience work overload, stress, and burden. We conducted a long-term field study in three geriatric residences to understand the work conditions of caregivers with the aim of developing technologie...

The automatic detection of behavioral changes in older adults living in geriatric centers is relevant for physicians and caregivers. These changes could indicate an incipient symptom of a disease or a steep decline in the health of the person. Abnormal pattern discovery has been studied in the context of an array of (wearable) sensors (i.e. acceler...

People suffering from dementia exhibit abnormal behaviors that can put them at risk or burden their relatives and caregivers. Many of these behaviors have acoustic manifestations, such as shouting, mumbling, cursing or making repetitive tapping. In this paper we propose an approach for detecting disruptive behavior manifested through audio. The sol...

Pervasive healthcare aims for a decentralized, preventive, and assistive approach to healthcare. Recognizing their merits, many authors have proposed systems based on this approach; some include theoretical proposals and architectural designs, while others have implemented real working systems. Most systems are tested in controlled laboratory condi...

La población mundial envejece y los adultos mayores requieren de cuidado especializado que es difícil de garantizar sin utilizar ayudas tecnológicas. Por esta razón se realizó un estudio de campo para conocer las necesidades dentro de residencias geriátricas, los métodos y procedimientos para el cuidado de adultos mayores en tres diferentes institu...
