There is a possibility that vast amounts of undersea resources are buried beneath Japanese territorial sea. In order to find these undersea resources, a detailed topography including specific objects and events of seabed should be carefully surveyed. One of effective methods for this is to use seabed visualization technologies, which are applied to an autonomous underwater vehicle (AUV). Therefore,...
Childhood asthma has effectively doubled since 1980 and currently affects about 8% of the U.S. childhood population. Efficiently analyzing quality of air data, which would ultimately improve the information available to parents with children suffering from asthma, is crucial to reduce the likelihood of a serious attack. In order to accomplish this task, the use of low-cost, wearable, environmental...
In monocular vision systems, lack of knowledge about metric distances caused by the inherent scale ambiguity can be a strong limitation for some applications. We offer a method for fusing inertial measurements with monocular odometry or tracking to estimate metric distances in inertial-monocular systems and to increase the rate of pose estimates. As we performed the fusion in a loosely-coupled manner,...
Vision is a potent source of information, not just for humans, but for robots as well. Processing visual information is a computationally expensive task, one that is often difficult to accomplish in real-time on embedded hardware. In the broad field of visual research exists egomotion estimation, the process of determining self-motion from optical flow. Here we show a technological adaptation and...
Acelerated development of new technologies of information and communication many processes have been optimized. Also, the integration of automation in the electric sector has caused a notable impact generating advanced mechanisms for the generation, transmission and distribution of electrical energy. In this sense, the systems of control and monitoring of electricity consumption represent an important...
In this work, the principal aim is establishing networks parameters of wireless sensor. These devices can transmit variables to monitoring the quality of tourist beaches in the Colombian Caribbean. We propose a methodology to choose the network elements and its technologies. We analysis data based on coverage and implement the prototype. We show that the maximum distance between nodes is 33 m at mesh...
Urbanization is accelerating worldwide, giving rise to serious traffic problems. Traffic wave, known as stop-and go traffic or phantom intersection, is one of the most significant traffic oscillation patterns studied in Traffic Engineering. Usually these studies are numerical experiments that investigate specific places, such as a crossroad or a highway section, and their findings cannot, therefore,...
We conducted a study to investigate how learning styles related to the introductory Computer Science I course: the learning styles of the student population that took the course; course completion rates as they related to learning styles; relationship between the final grade in the course and learning styles; and the correlation between project and assignment completion rates and learning styles....
In the decommissioning of the nuclear power plant, especially, for decontamination by radioactive substances caused by 2011 Fukushima nuclear power plant accident has affected the reconstruction after the earthquake, the dose evaluation and validation of the decontamination effect is very important. In order to prepare a novel passive-type dosimeter system which can applied to radiation dose monitoring...
This paper presents the use of a new concept: Internet of Things (IoT), applied to the fermentation process of Cocoa at the Piura's mountain range. A prototype was designed and built with sensors that record the variables of temperature, oxygen and carbon dioxide during the process and send this information to the Internet. Finally a system has been developed that receives this information, visualizes...
Camera-enabled sensors deployed for visual monitoring will cover a region of the target field, providing information for many innovative applications based on wireless sensing. Actually, some areas of the monitored field may have more relevance than others, according to the characteristics of the applications, which may indicate that such areas need better coverage to avoid blind spots and achieve...
The tonic postural system guarantees the stability of the human body in upright stance and during locomotion. It is considered as a complex organization which involves several internal systems and has multiple sources of information. In this paper, we provide a review of techniques and materials for human stability assessment. The primary tools to record and evaluate human sways in static posture...
Anticipating human intention by observing one’s actions has many applications. For instance, picking up a cellphone, then a charger (actions) implies that one wants to charge the cellphone (intention) (Fig. 1). By anticipating the intention, an intelligent system can guide the user to the closest power outlet. We propose an on-wrist motion triggered sensing system for anticipating daily intentions,...
We present a virtual system for strengthening of lower limbs focused on children with cerebral palsy, in the implementation we use sensors that allow to obtain the angular velocity and rotation of direction of the bicycle, for the design of the virtual environment we use the Labview software, in which two scenarios of different difficulty are created to visualize in virtual form the trajectory that...
This article presents the design of a telecommunications network that allows the monitoring of mud, earth, rock and debris flows produced by slope overflows in the main arterial roads of the city of Cuenca, Province of Azuay. This network is integrated in a system of monitoring of the SIS ECU 911 of the City of Cuenca. The system has been conceived as a set of devices such as wireless modules and...
A Smart Wheelchair (SW) is an electric powered wheelchair, equipped with sensors and computational capabilities, with the general aim of both enhancing independence and improving perceived quality of life of the impaired people using it. SWs belong to the class of semi-autonomous mobile robots, designed to carry the user from one location to another of his/her choice. For such systems, the localization...
This paper presents new approaches for construction of knowledge-oriented control systems. The AND/OR-graph model is improved for control rules visualization and interactive processing. The knowledge-oriented system for the dispatcher that regulates the safe operation with electrical equipment made it possible to increase the reliability of decisions taken by the dispatcher by 12%.
This article presents a system for determining the position and orientation of unmanned aerial vehicles. The system has two hardware layers coupled in both directions. One layer stabilizes the vehicle while the other determines lateral displacements. The two-directional coupling between layers allows the system to minimize estimation errors. The proposed implementation is evaluated on real hardware...
The use of smart devices has become an integrated part of our everyday life. Communication is now possible any place and any time. The distraction caused by these devices, however, can lead to potentially dangerous situations. To mitigate these situations, various researchers have proposed and developed solutions to analyze the environment and to alert the user if a situation is evaluated dangerous...
We investigate whether socio-psychological aspects — such as empathy and grouping (swarming) — implemented in caribou agents improves the efficiency of the simulated evolution (via genetic programming) of their escaping behavior or the effectiveness of such a behavior in the wolf-caribou predator prey pursuit problem (WCP). The latter comprises a team of inferior caribou agents attempting to escape...
