We present the design of a magnetic encoder to measure angular position. The proposed encoder includes two Hall sensors in quadrature in a fixed platform. In addition, and over the sensors, there are two permanent magnets in a shaft. The relative motion between the fixed and the movable components generate a voltage variation in the sensors, which serve to generate the approximation of the angular position. We detail the acquisition process and the linearization method, because we consider that these are the most important contributions of this work. Lastly, we show the application of the encoder in the position control of a direct current motor to show the performance of the encoder estimating fast and slow angular position changes.

This paper shows a mobile robot whose purpose is to provide comfort and meet various needs that may arise in family homes. This mobile has different sensors that allow monitoring the house remotely, since it has a direct connection between the user and the robot through a graphical interface connected to a wireless network, which shows all the readings of the sensors among other things. The sensory system sends orders to the different actuators that perform the order programmed by the user

A methodological strategy is proposed for the teaching of Linear Algebra in engineering programs focused on plausible reasoning. These concepts were developed by [1] and [2], through the formulation and adaptation of interesting problems, whose design admitted a didactic model and a methodological procedure for the generation of conjectures through the mediation of technology and geometric visualization as key factors in the construction of the main concepts of the discipline by the students. The difficulties in the teaching and learning of Linear Algebra have been studied since last century, in particular since the nineties. The LACSG (Linear Algebra Curriculum Study Group) in the USA is a reference point. On the other hand, Anna Sierpinska and Jean-Luc Dorier lead another group in Canada and Europe. Both groups coincide that one of the greatest problems in the teaching and learning of Linear Algebra is the formal approach of the classes that are traditionally taught. The starting point of this study is the great difficulties students experience when assimilating definitions, theorems and demonstrations, which are elusive for the future engineers.

The objective of this project is based on the design and manufacture of a mechanism for a didactic product, awakening the interest of those who have affinity to horses and their skills. It is intended for people between 20 and 50 years old. Ergonomic, functional, use, aesthetic, structural and mechanical aspects were taken into account. In addition, the mechanisms were verified through the Working Model and SolidWorks software, with their corresponding static and kinematic calculations of the mechanism. The purpose of the project was to design a toy in the shape of a racecourse where there were two horses in competition, these displacements being generated by a crank movement exercised by the user, which was determined by kinematic calculations with the use of polar coordinates, finally we developed a prototype in scale 1-1 where we observed the speed of movement, the trajectory and the time it takes to carry out the activity. We conclude that for the development of competitiveness it is necessary to use a train of gears, which allowed the reduction of speed and the linear movement of the horse

Linked Open Data has been an initiative aimed at offering principles for the interconnection of data through machine-readable structures and knowledge representation schemes. At present, there are platforms that allow consuming LOD resources, being CKAN one of the most relevant on a large community made up of governmental organizations, NGOs, among others. However, the resources consumption lacks minimum criteria to determine their validity such as level of trust, quality, linkage and usability of the data; aspects that require a previous systematic analysis on the set of published data. To support this process of analysis and determination of the mentioned criteria, this paper has as purpose to present a method that allows analyzing the dataset current state obtained from the different instances published in CKAN, with the aim of evaluating the levels of trust that can offer from their sources. Finally, it presents results, conclusions and future work from the use of the tool for the dataset consumption belonging to certain instances ascribed to the CKAN platform.

It is given that in Bogotá public transport system moves approximately 29.18% of the population, it is essential to ensure that the features of the service provision are the most appropriate for its users; for example, the support bars inside the vehicle are not at an adequate height according to the physical characteristics of the users, generating risks within the vehicles. Due to this failure has not been resolved in its entirety by the service provider is important to implement a method that allows adequate grip to the fasteners, considering this, the project aims to develop a system of grip and support that reduces the risks of physical damage to the user during his trip. This system will allow users who are in the orthostatic position (standing) to anchor themselves in a simple way of the elements incorporated in the vehicle. The development process was carried out using a combination of the Ulrich and Schnarch methodologies

Radio frequency signal generators (RF) are instruments used to test reception equipment and RF components like filters, amplifiers, attenuators, among others. On the other hand, they reinforce the teaching-learning processes and they are widely used in research in the telecommunications field. This document provides the first stage of a low-cost signal generator design by using RaspBerry Pi 3, with the documentary exploration about this kind of applications. After that, a recognition of the RaspBerry Pi 3 is done at hardware and software level. Finally, an application of an FM signal generator with RaspBerry in a frequency of 101.3 MHz is evaluated, which does not require any additional hardware. This signal was captured using a spectrum analyzer, which determined good quality of the modulated signal in terms of power, bandwidth and SNR (Signal Noise Ratio). However, there are some unwanted harmonic components
