This work describes the way in which serious games are used in virtual reality for fine motor rehabilitation in an upper limb, as a possible rehabilitation tool for patients who have suffered a cerebrovascular accident. A glove equipped with flexible sensors was built, which allows to move a virtual hand on the computer. A virtual environment was implemented in Unity 3D where the patient is registered, and where his rehabilitation is stimulated through four games under the supervision of the therapist. The four implemented games allow developing the spherical, cylindrical and pincer grasp, as well as the global mobility of the fingers. The system was tested with 12 users. It is expected that the project developed can become an additional tool for the therapist to schedule various rehabilitation sessions for the patient. [ABSTRACT FROM AUTHOR]

What is the role of communication media in the industry and fashion culture in a country like Ecuador? It is necessary to start by understanding the fashion system and how it has been disseminated through its own languages and symbolisms, in order to understand the impact it has generated on local cultural codes. Communication has played a special role in food imagination, consumption and business that does not respect local meanings. In fact, you have never played a leading role in the visibility of those who are "ajenos", completing the concept of the national and how we define local fashion. Fashion communication formats are in a disruptive moment that puts a traditional system to the test while making it increasingly necessary to see fashion beyond brands, media and characters. The need to analyze communication formats and their contents in the cultural impact of the development of this industry, which has had environmental, economic and social interference in Ecuador, is not negotiable.

Due the worldwide growing food demand, efforts toward to resource optimization in crops, are required. With this purpose, the use of technology is a big chance to deal these challenges, with the aim of automatizing agricultural processes. Within the tasks in agriculture, by example wedding, supply fertilizers or fungicides, the mobile robots have a potential use to assist these tasks. Then, from this work, velocity control of a differential mobile platform is developed, in order to perform precision agriculture tasks. Specifically, mathematical modelling, design of state feedback control and the integration to the robot hardware, through Hardware in the loop (HIL) simulations, validation test are performed by using ROS environment, embedded devices and mathematical simulations, at previous stage to real test. Showing a full integration of the proposed system to test and prove mobile robots. [ABSTRACT FROM AUTHOR]

This paper presents an algorithm oriented to improve the security conditions of electric power systems. The proposed algorithm performs a semi-exhaustive search of the possible configuration of the system substation with the objective of minimizing overloads presented in single contingencies (N-1 criterion). Topological modifications are made by changing the state of switches in substations. Results are presented for the IEEE 118 bus test system showing the effectiveness of the proposed algorithm.

It is presented a system to detect pulses by using a piezoelectric sensor. Basic proofs were made using commercial piezoelectric ceramics and others obtained in our laboratory. Very good results were obtained. The system allows detecting the pulses, which are generated by the piezoelectric material when a mechanical stress is applied. A data acquisition program was developed for the signal records, analysis and comparison of the results. [ABSTRACT FROM AUTHOR]

This paper presents a lineal optimization model to solve the hydrothermal coordination problem. The main contribution of this work is the inclusion of the network constraints to the hydrothermal coordination problem and its solution using an interior point method. The proposed model allows working with a system that can be completely hydraulic, thermal or mixed. Results are presented on the IEEE 14 bus test system. [ABSTRACT FROM AUTHOR]
