Fusion of sensing mechanisms inside mobile devices (e.g.: GPS, accelerometers) have driven the growth of context-aware mobile applications. Currently, there are building approaches for this kind of applications, but these do not have the flexibility, for example, to derive applications combining different location sensing mechanisms. In this paper, we present a first proposal of a taxonomy of factors that could be considered by context-aware mobile application building approaches, in order to provide variability in the kinds of derived applications. The aim is to generate a discussion that can contribute to the unification of aspects that should be addressed by these building approaches. To complement the taxonomy, we present the analysis of an interview that was conducted with regard to developers who use (or could use) these building approaches. We hope this will enrich the discussion in relation to this kind of approaches.

The Farmbot Cartesian robot is an open source project so that updating modifications are possible for both hardware and software in order to enhance involved processes framed by orchard and nursery environments. Currently on Farmbot project there are no relevant contributions about joint synchronicity, closed-loop motion control and kinematics formal model as a matter of improving trajectory planning without jerks and cumulative error. Taking into account, then, mechanical structural features, stepper motor angular acceleration, velocity and resolution, as well as motion transmission system in this work the kinematics, the relation between velocity motion joints and the robot end-effector velocity based on Jacobiano and cubic Spline interpolator are modelled to meet a better PTP (point to point) trajectory planning. In order to validate what is proposed a 3D virtual environment for the robot is designed (through Matlab/Simulink) that does possible display motion paths generated by equations obtained in previous steps. Finally, simulations are performed and the results showed and discussed.

This document presents the design and implementation of a platform that detects the ON/OFF state of any electronic device and show this information through an Internet web site despite the absence of any Internet network. The device state is defined through a current sensor, the information is saved with date in a backup memory, and then, a Short Message Service (SMS) message containing the ON/OFF state is sent to a massive message platform on the Internet. After that, the information is collected in a custom web platform where the user can access through the Internet and see the electrical status of the device. Additionally, the platform works even when there is not AC power supply.

This paper presents a thorough evaluation of a single-channel electromyography (EMG) signal acquisition board based on Arduino technology to characterize the swing phase of normal gait. A total register of 231 EMG signals corresponding to 11 lower limb muscles (7 right and 4 left) of 21 subjects was generated. For each record, the subject made a coordinated paused walk based on a sequence of audible tones to indicate each step. The maximum amplitude (MA) defined as the maximum value of the amplitude of the rectified and smoothed EMG signal corresponding to each of the swing sub-phases (initial, mid and terminal) were compared for the left and right limbs. The MA between swing sub-phases were also examined. Results show that the amplitudes obtained in each swing sub-phase of the gait records are coherent with the normal swing phase. These findings allow to recommend the use of the EMG acquisition prototype for studies addressed to the detection of motion intention.

This work proposes an algorithm to measure the variation of joint angles of the extremities of Peruvian Paso Horses through the use of inertial sensors to obtain an estimation of their characteristic movements known as "pisos". These angles will be measured in the frontal and sagittal planes, and a complementary filter will be used to reduce the SNR and thus the percentage of error. Finally, an algorithm computes the corvejón" angle, as well as the "Término", "Agudez" and "Acción" angles. These are shown in an angle-versus-time plot for zootechnicians to analyze and draw conclusions regarding the performance of these animals.

In this work an extraction method is proposed to obtain the electric and physical parameters of Ultra-Thin Body and Buried Oxide (UTBB) Fully Depleted SOI MOSFET with short channel length (below 100 nm). In order to check the accuracy of the extraction method, model is built using a TCAD with these parameters. We found that the simulation shows a very good agreement with the experimental curves. However, an improvement of the mobility model and a better definition of the extension of the model used in the TCAD is needed to get a perfect matching between the experimental and the simulated curves.

This paper presents the design of a control strategy for the tracking control problem of a three-axis cartesian-robot based on optimal preview control, where the current and future desired position of the robot are used to calculate the control signal which allows accurate tracking of the desired trajectory. In order to give robustness to external disturbances, an observer capable to estimate any state vector for linear systems with unknown inputs is designed. The effectiveness of the proposed control strategy is verified by simulation for linear and nonlinear trajectories, where preview control improves the tracking accuracy. Likewise, the effectiveness of the unknown input observer is verified by applying a disturbance as an additional input to the system.

Currently, the city of Cerro de Pasco is officially in emergency due to the high level of contamination of its natural resources caused by the open pit mine that exists in the middle of the city and something more dangerous, air pollution by waste toxic substances that pile up inside and around the city. In this sense, this research proposes and develops the detection of the percentage of lead sulfide and zinc oxide, scattered in the city, using the digital processing of multispectral satellite images. As a result of this mineral detection, it is obtained that more than a quarter of the area of the city, it contains minerals scattered in urban areas.

The latent global problems present in the teaching to children with disabilities can be seen on the construction of plenty of prototypes used in this area. On this work, it is presented a multi-sensorial system to help the teaching-stimulation processes with the children suffering from brain paralysis, which was developed with the therapists. For this, an embedded system is presented; this is formed by three main stages: in the first one there are the therapist, the family and the mobile application, on the second one there are the master devices with their feedback system, and on the third one there are the three slave gadgets and the child for the basic colors and/or geometric shape selection. For the validation tests, three therapy sessions were carried out. The stimulation is auditory, visual, and motor; each one with 19 requests about different topics that can be colors, shapes, and the combination of both. Due to the system is Wi-Fi, the tests are carried out in two different environments.
