Technological advance has demanded creation of electronic control devices called Software. In this context the technological industry has generated exaggerated income at the expense of users who don’t know which are their true requirements and, thus, cannot choose freely what they need to perform tasks of daily life, relapsing in unnecessary expenses and “investments” and generating benefits for certain sectors. This essay aims at providing a global opinion on what is called Software and knowing their different forms to perform and make related decisions with freedom. All this because it’s necessary to have user role awareness and, in this way, help improve user's’ current situation as individuals in constant relationship to other subjects.

The most used rehabilitation methods for people with amputation is the prosthesis. A transtibial prosthesis is an artificial limb that replaces a leg missing below the knee. To achieve the proper fit between the prosthesis and the person, the alignment of the prosthesis is performed, this will allow the amputee subject to have stability, comfort, adequate distribution of forces and moments, ipsi and contralateral equality, among others. Static alignment tends to be subjective, it is performed in an observational manner by experts in the field. The present investigation shows a proposal to perform the static alignment in an objective way, based on the distribution of pressure on the plantar surface and the location of the Pressure Center COP). With the use of machine learning systems, such as the vector support machine (SVM), and the named biomechanical variables, a computational tool was generated that shows if there is alignment of the prosthesis. A yield close to 100% was obtained with the proposed model. It is verified that with the use of technological resources in the area of rehabilitation of amputees can perform objectively the static alignment of transtibial prostheses.

In the city of Tunja there are no sources of information and exact indicators that establish the amount of tires used and discarded in clandestine dumps, house yards and storage centers, which generate negative impact on the environment and the health of the inhabitants, evidencing the need to generate a logistic solution. An investigation of quantitative approach of type applied as a case study is presented. The CVRP method was used, which consists of the design of a set of routes of lower cost, where each client is visited only once by a single vehicle and all routes begin and end at a center of gravity; as results, the characterization and design of a logistic model was achieved, which integrated the location of collection point, demand, collection routes, capacities, as a solid and updated tool that would generate environmental alternatives for the city.

Objective: perform a literature review on the behavior of harmonics a cause of LED lighting. Method: raise an in-depth research on Bibliographic Indexes (IB) and Bibliographic Bases with Selection Committee (BBCS) on Harmonics in LED lighting. The following article presents the electric behavior of LED illumination focused on harmonic distortion, analyzing topics such as harmonic generation, harmonics standards, harmonic solving, among others; each topic mentioned is accompanied by its respective citation to guarantee the copyright and give the reader a dynamic movement between what is stated in this work and the works cited. Results: a thorough investigation was carried out in detail, focusing on the harmonics in LED lighting, analyzing its current state and consequences with respect to other conventional luminaires and the energy system.

This article explains the way to supervise the rotational grazing fieldu using image processing. The system facilitate the job development because rotation decisión is only for farmer with his experience define if it is ready or not for cut, and reduce times to define places without go over the fields. Image segmentation and it’s treatment avoid determine an strategy to automate and select fields sistematically.

This research was developed to compensate for the low supply of sensors that handle the TCPIP communication protocol, and its high cost in the market, therefore, the need to make a new proposal for a lower cost industrial sensor is identified. The project was developed on an FPGA contained in a development card that has an Ethernet port and an embedded processor installed in it, communication is established to transmit the data taken by an ultrasonic sensor and send them with the TCPIP protocol

This paper presents the analysis and implementation of both logical and physical topology of the superintendency of ports and transport, which describes the basic concepts used, the methodology used and the results obtained, which concludes with an analysis of the network implemented in order to verify the effectiveness of the project in the state. For the implementation of this project has the technical and management support company Techlan solution Ltda Similarly the Universidad Distrital as a center of knowledge and development for the proper execution of the project in question.
