V International Conference on Science, Technology and Innovation for Society (CITIS 2018-2019)

The V International Conference on Science, Technology and Innovation for Society, CITIS 2018-2019, held from February 6 to 8, 2019 and organized by Universidad Politécnica Salesiana, offered the national and international academic community a unified communication platform, aimed at cover the theoretical and practical problems with greatest impact on modern society through an engineering perpective.

In this edition, dedicated to the 25 years of life of La Salesiana, the thematic axes were related to the application of science, technological development and innovation in five fundamental pillars of our society: Industry, Mobility, Environmental Sustainability , Information and Telecommunications.

The scientific committee consisted of 48 researchers from ten countries: Spain, United Kingdom, Italy, Belgium, Mexico, Venezuela, Colombia, Brazil, United States, and Ecuador.

Almost one hundred contributions were received, of which 39 were approved as formal research papers and 15 in poster format. These contributions were presented orally to the entire academic community that met at the conference, who from the Aula Magna, the Auditorium and the Multipurpose Room respectfully fulfilled the responsibility of representing the entire Society in the review, acceptance and validation of the new knowledge that was presented in each presentation by the researchers.

In parallel to the technical sessions, the conference had presentation spaces for scientific posters and five workshops on avant-garde themes that captivated the attention of our teachers and students. Also, in the framework of the event a total of eight Keynote Conferences were given on current topics such as knowledge management at the University-Ecosystem, the challenges and opportunities of Industry 4.0, the advances of basic and applied research in mechatronics for the study of new generation robots, optimization in engineering with multi-objective techniques, the development of advanced networks in Latin America and the universe, air pollution due to vehicular traffic, radon and the risks that this radioactive gas represents for human health, among others.

But CITIS was not only science and research, as the workshops, keynote conferences and technical sessions were complemented by artistic, cultural and recreational activities. It is worth highlighting among them: the Guayaquil cultural afternoon, the photographic exhibition with augmented reality animation “France in motion” and the exhibition of the Robotics Club of the UPS Sede Guayaquil with mechatronic prototypes developed by our students that have been multi-awarded in national and International events.

WORKSHOPS

WORKSHOP 1: SETTING OF PID CONTROLLERS THROUGH MULTI-OBJECTIVE TECHNIQUES

It is possible to consider the task of setting PID-type controllers as an optimization problem. Typically, this is done by carrying out the optimization of a performance index (also known as a cost function or design objective). However, it could happen that the optimal solution found does not satisfy the exchange of benefits of all the control requirements. This workshop addresses this optimization problem from a multi-objective approach, where a set of Pareto-optimal solutions are calculated. The foregoing provides the engineer with alternatives for the selection of the solution most suited to their needs, following a process of multi-criteria analysis of the exchange of benefits between conflicting objectives.

Objectives: The participant will understand the design process through multi-objective optimization as a holistic design technique for engineering, where the definition of the multi-objective problem, the multi-objective optimization phase and decision making converge. This technique will be used for the adjustment of PID type controllers.
Required skills: management and programming of Matlab (elementary).

Required knowledge: Optimization (elementary), PID controllers (elementary).

In the workshop, contents of the book: G. Reynoso Meza, et al. “Controller Tuning with Evolutionary Multiobjective Optimization.” (2017). Intelligent Systems, Control and Automation series. Editorial Springer, will be covered.

Also will be covered referential content from the book (in edition): G. Reynoso Meza. “A gentle introduction to engineering design with multiobjective optimization.”

WORKSHOP 2: CLOUD COMPUTING AND DATACENTERS

The participants in this workshop will get a panoramic view of the data centers, that is, the technological infrastructure that supports cloud computing. Cloud computing is defined as a model that offers on-demand computing services, such as:

SaaS (Software as a service), model that provides software applications for end users via the Internet: e-mail, office automation, storage, etc.
PaaS (Platform as a service), a model that provides platforms for the development of software via the Internet as programming languages and libraries.
IaaS (Infrastructure as a service), a model that provides the physical infrastructure that in turn allows PaaS and SaaS to be supported, such as servers, networks and computer laboratories via the internet, supported in Data Centers.

Finally, the IEEE Cloud Computing initiative is addressed, as well as industry trends in data centers and the main industry standards. At present, ICT graduates find employment in data centers and network operations centers in telecommunications suppliers.

WORKSHOP 3: SUSTAINABLE MOBILITY: ENERGY AND ENVIRONMENTAL EVALUATION OF VEHICLES

There is currently a great concern about the differences between fuel consumption and actual emissions shown by vehicles and those reported by manufacturers. These differences generate important errors in emissions inventories and in the formulation of public policies for the control of vehicle emissions.
This workshop will illustrate how energy and environmental performance of vehicles is evaluated for regulatory purposes. Subsequently, the existing tools to estimate the energy consumption and emissions of vehicles under particular conditions of a region of interest will be shown. Finally, these tools will be used to estimate the number of batteries required in electric vehicles.

WORKSHOP 4: CONCEPTUALIZATION AND DESIGN OF MECHATRONIC PRODUCTS

What makes new technological products to have better benefits, to be more competitive, and still continue to be attractive and effective in the market? New products are generally planned from the concept, and parametric and functional specifications are then defined according to the behavior and maturity of the target market niche as well as its segmentation. These problems are usually addressed at a managerial and industrial engineering level, but today they may be also aproached from the mechatronic engineering perspective. In this context, this workshop will address the essential aspects that influence the definition, generation and selection of the concept as a basis for new competitive products, particularly from the closed loop mechatronic design paradigm. This paradigm seeks to establish the causality of each and every one of the design and functionality elements that define and prioritize prototype features, and how they evolve towards a competitive product in the market. We will deepen in technical aspects of functional definition of the product, as well as the techniques of concept, modeling, design, sensors, actuators (and their control), protocol tests, project management, up to the product cycle. We present several case studies, and organized in teams, we will develop design proposals for a mechatronic product, in a hypothetical but realistic environment.

WORKSHOP 5: OPTIMIZATION OF CONVERTER TOPOLOGIES WITH SILICON CARBIDE DEVICES FOR ELECTRIC TRACTION SYSTEMS

The proposed workshop comprise the study and analysis of different topologies of three-phase converters used in electric traction systems. The first part contemplates a complete revision of the topologies of converters with VSI voltage source, CSI current and with impedance networks (Z, Qzsi). All these topologies are contemplated for their implementation in electric traction systems. The second part of the workshop deals with the use of silicon carbide (SiC) devices in the topologies named above. The use of SiC devices allows to work with higher switching frequency, greater operating temperature range and reduced power losses, which means an increase in the inverter system efficiency. The main objective in this second topic is to show the advantages and disadvantages of using this technology in this type of converters and how it is possible to get an optimization in size, weight and efficiency. This has undoubtedly generated expectation among manufacturers and research groups dedicated to electric traction. Within the whole subject, different modulation techniques used in the present are analyzed, and also specific control topics used for these topologies of inverters and electric motors are discussed.

KEYNOTE SPEAKERS

Dr. Vicente Parra Vega – Research Center for Advanced Studies (Cinvestav), México

“Basic and Applied Research in Mechatronics for the Study of New Generation Robots”

For decades, the technology of manipulative robots has materialized, first as a proof concept in research laboratories and later in the manufacturing industry and high added value services. Its growth has determined the industrial robotics sector to become an important indicator of economic development of nations. However, it was in this last decade when a new class of robots broke into the international market, particularly in emerging industries. What made this possible? What kind of knowledge and technology enabled such a technological revolution? In this brief talk, we discuss some fundamentals and essential aspects of robotics, and the benefit of addressing their problems from the mechatronics. In particular, some problems of basic and applied research of emerging robots (which, unlike industrial robots, do not comply with ISOs) that are already on the market, will be deepened. We will briefly discuss recent problems and results of concurrent engineering research and mechatronics, which have contributed substantially to the advent of this generation of robots. Finally, some open problems that transcend the state of art and define the future of this technology are pointed out.

“An introduction to engineering optimization with multi-objective techniques”

Many of the engineering problems are modeled as an optimization problem, typically by mean of a performance index (cost function or objective). However, it may happen that the optimal solution to be found does not satisfy the engineer / designer in charge.
Then,what to do then when an “optimal” solution is not enough? This talk addresses this problem from a multi-objective approach, where a set of Pareto-optimal solutions are calculated. The above means that given two (or more) conflicting design objectives, a set of optimal solutions is calculated, with different degree of compromise between the design objectives. This strategy provides the designer with alternatives for the selection of the solution that best suits their needs, following a multi-criteria analysis process. A general perspective of the design process will be provided through multi-objective optimization, presenting it as a holistic design technique, where the definition of the problem, the optimization phase and decision making converge.

“Air pollution near roads: an experimental and numerical simulation study using CFD”

Seeking to advance the understanding of the dispersion of pollutants near vehicular roads, the conference will address the results of an experimental study that measured vehicular traffic, relevant meteorological parameters and the concentration of particulate matter (TSP, PM10 and PM2.5), simultaneously, in different spots of two unpaved roads, located on flat terrain in a region without any relevant additional source of contaminants. With these data an air quality model to simulate the dispersion of particulate material and gaseous pollutants emitted was implemented through a commercial software of computational fluid dynamics (CFD). The results of this research can be used to determine the size of areas impacted by vehicular roads, identify mitigation measures, adapt and improve the accuracy of emission factors.

“Advanced Networks in Latin America and the worlds”

This talk offers a panoramic view of advanced networks or what we know as Internet 2 both on the ground and on the interplanetary internet. On the one hand, Internet 2 is interconnected worldwide under the name of academic networks, whose requirements are a speed and a backbone infrastructure of high-performance switches and routers, and on the other hand, interplanetary Internet is developed as part of the colonization of Mars and other planets. Today, all commercial internet provider companies use IPV4 tunnelled with IPV6 or directly implementations with IPV6, and in fact IPV6 was developed in the advanced network environment, as well as a variety of protocols and services that are subsequently implemented in the commercial Internet. Advanced networks should be strategic for every country, Germany for example and start with the construction of your Internet 3.

“Industry 4.0: Challenges and Opportunities”

Since the first industrial revolution, technological advances have generated the pronounced growth of industrial productivity to reach the automated industry in the 1970s. In recent decades, advances in mobile communication and information technology have placed us in the middle of a fourth wave of technological advance, which has led to the digital transformation of the industry: the Connected Industry, or also called Industry 4.0, where sensors, machines and information systems can be connected throughout the entire value chain to achieve an intelligent industry focused on the product and the customer. However, the mere connection is not enough. Digitization of the industry is only an enabler of other analytical and reasoning processes that lead to an integrated, efficient and flexible industry to produce high quality goods at reduced costs. In this sense, the Industry 4.0 paradigm proposes challenges on how to apply and implement such processes along the value chain. Similarly, the development of Industry 4.0 offers opportunities to achieve sustainable manufacturing in different areas of the production process: in business models, networks of value creation, in the model of the organization, in human resources, as well as in the processes and products. Thus, there are challenges and opportunities that must be understood in each context, which allows even small and medium-sized industries to begin to move the path towards Industry 4.0.

“Internet of things: A look to its research, innovation and development”

Every year the growth of the Internet of Things (IoT) exceeds the forecasts established by regulators and device manufacturers. During last year, IoT has gone from being a futuristic vision, sometimes with a certain degree of exaggeration, to a reality that is growing. This increase will generate changes in traditional businesses and, consequently, reduction of human intervention. IoT is the idea that everything can be connected anywhere and at any time. The concept can be applied to all sectors that involve the daily life of human beings, such as: personal care, housing, transportation, health, agriculture, e-government, education, automotive industry, e-commerce, business, among others. This talk presents a summary on research, innovation and development of existing IoT projects, their main challenges and obstacles.
