A survey of Genetic Improvement of Software Systems
Genetic improvement uses computational search to improve existing software with respect to a user-defined objective function, while retaining some existing behavior, usually captured by testing. Work on genetic improvement has already resulted in several awards. This includes work on automated program repair. GI has been used, for instance, to automate the process of software specialization, optimize program efficiency, and to minimize memory and energy consumption. GI has also been used to transplant functionality from one software to another in an automated way. I will give an overview of the genetic improvement area and present key components of a GI framework.

Stability of Converter-Based Power Systems
The development of renewable energy is fundamentally changing the power grid. While the percentage of electricity produced from renewable sources often receives most public and political attention, the underlying physical transformation of the grid is more profound and creates many technological challenges as well as opportunities for electrical engineers. With converter-based generation from wind and solar replacing conventional power plants, the grid is increasingly dominated by converters. Since the best renewable resources are usually at remove locations, new transmission infrastructures are also required to support large wind and solar projects, and HVDC transmission is often preferred because of its ability to work over long distance and to enhance, or black-start the local grid. This combination of converter-based generation and transmission, coupled with converter-based loads such as electronics, motor drives, and electric vehicles, is creating a future grid that is very different from conventional power systems.
This talk gives an overview of the growing applications of converters in power systems, discusses the fundamental differences between converters and machines, and presents a frequency-domain method for stability study of converter-based power systems.

Set-based approaches for diagnosis and fault-tolerant control
This session reviews the use of set-based methods in fault diagnosis (FD) and tolerant control (FTC). Set-based methods use a deterministic unknown-but-bounded description of noise and parametric uncertainty.
These methods aims to check the consistency between observed and predicted behaviour by using simple sets to approximate the exact set of possible behaviors (in parameter or state space). When an inconsistency is detected between the measured and predicted behaviour obtained using a faultless model of the systems, a fault can be indicated. Otherwise, nothing can be stated. The same principle can be used to identify interval models for fault detection and to develop methods for fault tolerance evaluation. Finally, some real applications will be used to illustrate the usefulness and performance of set- methods for FDI and FTC.

Energy storage in decarbonized power systems: role, technologies and trends
Energy storage is considered by many as the Holy Grail of future decarbonized systems, characterized by nearly 100% share of modern renewables, much more distributed and less controllable. This keynote speech first discusses the main reasons why massive amounts of energy storage capacity will be needed beyond this decade. Then, a brief overview is provided of those technologies which are most promising to fill the existing gap in stationary applications, with special attention to pumped storage and batteries. Finally, the main applications in power systems, from generators to prosumers are illustrated, and some prospective data regarding future deployments of energy storage assets are provided.

In search of emotional traces: detection of depression through social media
Every day the Internet witnesses a great amount of people activity in many different social media networks. They allow us to share –personal– information very easily, and with it, they offer us innumerable new opportunities for business intelligence, personalization, and health monitoring.
This talk aims to resume some of the work we have developed in the previous two years towards the detection of social media users suffering from depression. Particularly, it presents three machine learning methods based on the analysis of emotions, which are supported on idea that depressed and non-depressed users must show different emotion distributions and trends in their posts. The talk will conclude with a brief overview of our ongoing work in this task, considering the application of deep learning techniques and the development of cross-language solutions.

Vision and Challenges of CENACE Faced with the Pandemic
On August 28, 2014, the agreement to create the National Center for Energy Control (CENACE) was published, as a decentralized public body of the Federal Public Administration, sectorized to the Ministry of Energy, with its own legal personality and assets, residing in Mexico City.
The tasks assigned to CENACE were “to exercise the Operational Control of the National Electric System; the operation of the Wholesale Electricity Market and guarantee open and non-unduly discriminatory access to the National Transmission Network and the General Distribution Networks, and propose the expansion and modernization of the National Transmission Network and the elements of the General Distribution Networks that correspond to the Wholesale Electricity Market. The challenge is enormous given that electricity is the engine of economic and social development of any country, and it is the function of CENACE to execute the control in an effective and efficient way, but in a transparent and impartial way for all the actors of the National Electric System. Hence the importance of the vision that CENACE has and must have, and the challenges it must face.
inthis talk, a general overview is presented about the challenges CENACE faces every day, in its daily function, in harmonizing the different types of electric power generation technologies to satisfy the country’s demand for electric power, with adequate margins of safety and reliability, sustainability, sufficiency, quality and economy. This requires and implies many fronts to fulfill its basic tasks, among which we can mention, the application of technological developments, interaction and feedback to technology developers, strategies and synergies that must be done with participants in the electricity sector, as well as the interaction with research centers and the academic sector, both national and international.
