WORKSHOPS
WORKSHOP 1:Â WEARABLE TECHNOLOGY FOR MONITORING PHYSICAL ACTIVITY: HOW TO USE IT EFFECTIVELY
The use of portable fitness devices (wearable technology) for sports, medical and wellness applications has grown considerably in the last decade. The increase in demand for these devices by the average consumer has resulted in a highly competitive market. Energy consumption, distance travelled, step counting, sleep monitoring, and heart rate are some of the measures provided by such devices through smartphone applications, which aim to promote physical activity in the people. However, most of these devices have been criticized due to their lack of accuracy, precision and reliability, which has caused some of them to disappear from the market. The objective of this workshop is to introduce the participant to the fascinating world of wearable devices. For this, we will use inertial sensors (accelerometers and gyroscopes) with different characteristics. The workshop will include the following topics:
• Introduction to the applications and specifications of wearable devices
• Calibration and interpretation of inertial data (accelerometers and gyroscopes)
• Acquisition of data and basic tools
• Classification of physical activities
• Integration and synchronization of inertial data with video tools
To take full advantage of this workshop, trainees must have basic knowledge of Matlab®.

WORKSHOP 3:Â ELABORATION OF STATE-OF-THE-ART REVIEWS
The review of the scientific literature is one of the first phases in every research project, as this will allow us to know in depth our field of study, develop a theoretical framework and establish the appropriate hypotheses on which to focus our research. Systematic literature searches are usually developed with two objectives: (1) as the first phase of more complex research in order to know in depth a certain field of study, to develop a theoretical framework and to establish the appropriate assumptions to focus the investigation; and (2) as a methodology to be used in an empirical study when the objective is to analyze the publications to establish the state of the art in a certain subject (bibliometric study). In this context, as part of the workshop, we will present a five-phase scheme that will allow attendees to acquire basic skills for the development of a state of the art on the research subject of their interest. At the same time, general guidelines will be offered for the writing of bibliographic review articles.

Application of virtual models in the homologation of industrial products
This conference will summarize some of the knowledge developed at Instituto Universitario de InvestigaciĂłn del AutomĂłvil Francisco Aparicio Izquierdo (INSIA) in the Polytechnic University of Madrid, applied to the homologation of products through virtual models. The homologation through virtual models is included among the test possibilities admitted in the Regulation 2007/46 /EC for motor vehicle homologation and its annexed trailers, systems, components and independent technical units (Framework Regulation). In this regulation, the homologation is admitted through virtual tests, in line with some other regulatory acts as Regulations 58, 66, 93 and 107 of United Nations, dedicated to safety conditions of large vehicles (passenger or merchandise). The virtual homologation of these vehicles and other safety components, such as the parachutes (emergency brakes) of the elevators, has different characteristics concerning those on the physical tests. In virtual trials, there is no change in the results, unless the procedure incorporates it. In the virtual tests, it would not be possible to verify the conformity of the production, or if possible, it would be difficult to attain the same results in a physical test for a product manufactured years after the virtual homologation. Therefore, in this talk, we will intend to share the reflections on the characteristics that a virtual essay oriented to the homologation of a product (especially road vehicles) must have, and how the parameters’ variation can be modelled to get a statistical outcome that allows obtaining the range of results in which a certain probability of success can be found.

Solar-assisted heat pumps: technological trends and feasibility in Ecuador
The scarcity of fossil resources and climate change are driving the development of more environmentally friendly renewable technological alternatives for both electricity and thermal energy generation. Among these solutions are the heat pumps that are used in the generation of thermal energy in various applications such as preparation of sanitary hot water, heating of pool water and food drying. Although this technology is mainly used in isolation using ambient air as the main source of heat, in recent years solar-assisted heat pumps have been developed that have proven great energy efficiency. This solar assistance can be based on solar thermal technologies, photovoltaic solar technologies or even both of them. In this context, the conference will address the new technological trends of these systems and analyze the feasibility of their use in Ecuador.

Integration of capacity and production planning in the two-stage process industry
In industrial sectors with high capital intensity, immobilized productive resources degrade over time, leading to an increase in unit production costs or a loss of capacity. In this context, companies need to constantly monitor the conditions of their productive assets and plan maintenance activities to recover their performance and remain competitive. In addition, the replacement of productive assets at the end of their lifespan must be carefully planned to avoid shortages of products to customers due to large periods of unavailability, being, in turn, a perfect opportunity to adjust the production capacity. Thus, in favour of an improvement in the competitive position of these companies, there is a need to simultaneously plan capacity, production and maintenance decisions taking into account the associated costs, periods of inactivity, as well as the optimization of the new production capacity. However, traditionally these problems have been addressed separately both in the scientific community and in practice. In this talk, the potential benefits obtained associated with a real case of a two-stage process industry through the use of mathematical programming will be illustrated.

Optimal planning for deployment of heterogeneous wireless networks in applications of electric networks and smart cities
In the framework and concept of intelligent electrical networks, certain stages are determined so that a smart grid can be considered; therefore, the advanced measurement infrastructure (AMI) destined to transport information in a bidirectional way between the electric meter and the electricity companies, requires the deployment of a communications network with a reduced cost from the use of a heterogeneous wireless network that through multi-jump allows the connectivity of smart meters, concentrators, base stations, and electrical companies. Starting from this premise, the study of the massive deployment of sensors is no longer of sole importance for the AMI but the same problem is transferred to the field and concept of smart cities that require the deployment of several sensors with wireless communication to provide different services to citizens to improve their quality of life. Thus, the real design criteria of a wireless sensor network must contemplate multiple variables and from an optimization model, the proximity to a lower-cost solution can be achieved while guaranteeing the efficiency and reliability of the communications network destined to certain services.

Energetic behavior of electric vehicles with batteries and hybrid with fuel cells under experimental driving cycles
This talk will discuss the energetic behavior of two types of electric vehicle configurations. The first refers to a hybrid powertrain with a fuel cell that corresponds to an extended-range electric vehicle. This system includes two energy storage sources: a lead-acid battery pack with a capacity of 5.04 kWh, and a hydrogen bottle stored in metal hydrides with a 200 W power polymer membrane fuel cell. The second powertrain configuration refers to a pure electric vehicle powered by batteries. In the latter case, we have chosen lithium-iron-phosphate batteries with a capacity of 324 kWh. To obtain the results, experimental measurements of driving cycles with their corresponding height profiles have been used. The performance of the vehicles has been raised and a simulation model has been developed with a software tool for each type of drive train configuration. In this way, energy and fuel consumption data have been obtained through each driving cycle. The final part of the conference will show the results from two points of view. The hybrid fuel cell configuration is suggested as an energy solution to a specific mobility application, while the pure electrical configuration is more focused on sustainable mobility in the urban environment.
