The proposed methodology shows that eco-efficient building projects comply with environmental and sustainable strategies for the expansion of height with floors. Previous technical characteristics and parameters are considered, and these are divided into three main areas: water, energy, and inputs, in addition to a secondary area: housing density. The evaluation that was carried out showed that the water consumption parameter is the most expensive to manage for any construction company and tends to be very irregular in its percentage of compliance, since it depends on the customs of the inhabitants. The energy parameter is considered a complex aspect, since the use of private transport is expected to decrease. However, due to the customs and structures of cities, this is di...

The sEMG signals were obtained from the hand through a Myo bracelet with surface sensors. Myo surface sensors are able to detect the electromyographic signals generated by the muscles. The integration of the system was performed in Matlab's Simulink platform to process, identify, validate and control the robot through the electromyographic signals. The hand gestures analysis was performed using a temporal approximation that allowed the extraction of characteristics of the signals. It was determined that the parameters Electromyographic Integrated, Mean Absolute Value, Quadratic Mean and Variance have direct correlation with the type of Hand movement. In order to classify the first movements like spread fingers, wave right, wave left, elder and voor, we used 6 neural networks, which allow to activate 3 degrees of freedom of the robot. For the integration and verification of t...

This device allows the analysis of the involuntary movements of pronosupination generated in the upper limbs using electromyographic signals produced by the muscles of the forearm and an algorithm based on artificial neural networks. To materialize the device, fast prototyping like 3D printing and the V model-based mechatronics methodology were considered. As a result of this investigation, a mechatronics device in the shape of an exoskeleton controlled by an embedded system which analyses, processes electromyographic signals and using neural networks allows tremor and involuntary movements classification produced by each patient.

The operation of the solar catamaran “INER 1” electric propulsion (PV) is a renewable and sustainable model for passenger shipping in the Galapagos Islands. In this regard, the detailed study of the relationship between the variability of solar radiation, the abrupt change of tides due to changes in wind speed and direction, and the increase in tourists, according to dry and wet seasons, cause high energy consumption. The boats must absorb energy from the electrical grid of the islands; this energy is from renewable (solar and wind) and, mostly, of fossil origin so identifying the source of the energy absorbed by the boats is essential. The aim of this study was to select the most influential attributes in the operation of the solar catamaran “INER 1” in the Galapagos Islands....

For this reason, the human-robot communication interface plays a very important role when introducing these mechanisms in the indicated areas. The largest number of jobs related to robot control propose the use of interfaces to map robot actions using a joystick or a haptic device. However, the use of these elements requires training of the personnel working with the robots. For the teleoperation of robots, natural interfaces have been proposed that allow generating commands from bioelectrical signals of the human body. The signals, which have greater acceptance in the development of this type of applications are surface electromyographic signals (sEMG). Additionally, due to the use of surface electrodes, the acquisition of sEMG signals does...
