 Join us on the 6th of June, at 14:00, in room I-105 of FEUP, for the presentation of “Digital Culture and Cultural User experience”.

 Abstract:

The immense interest in academia and the cultural industry has been to augment users’ participation during their interaction with cultural artefacts by making them an actor in their own cultural experience. Cultural User eXperience (CUX) has gained momentum in recent years, and a factor that affects CUX is the cultural background and profile of the individual user. Users have their own cultural characteristics and preferences, they learn and interact differently with a particular artefact, and finally, they obtain a unique cultural experience.

CUX is an essential consideration that should be acknowledged and implemented when initiating the Cultural Heritage (CH) domain. It is beyond the usability of a cultural product or system. It includes both pragmatic and hedonic user factors that could influence a user’s positive experience when interacting with the system or product, leading to the effectiveness of CH activities. The diversity of visitors to cultural spaces is one of their unique attributes and is becoming a significant challenge for these venues to meet their visitors’ needs. How can they address the variety of interests and needs of all their visitors? Therefore, it is necessary to know visitors’ expectations when visiting cultural spaces.

The cultural tourists of today (at least in developed countries) travel more than the tourists of the past, and it is possible that the tourists of tomorrow will travel even more often, increasing the level of cultural user experience. Therefore, travelling, which was considered a ”luxury good” in the past, is an integral part of people’s lives nowadays. Also, tourists do not leave their previous experiences, motivations, preconceptions, and attitudes behind when they travel, the same way they leave their coats in the cloakroom upon entering a museum. Furthermore, the effects of a journey are not limited to the time spent at the destination. Tourists connect information and construct meaning before travelling to a place and continue to do so months or even years after their journey.

It is indisputable that cultural tourism destinations require detailed categorization of their visitors and their underlying motivations since not every person is motivated by the exact reasons for learning, experimenting, or self-exploring. Because of this assumption that cultural tourists are not alike, most of the literature in cultural tourism follows a clustering approach, emphasizing determining the typology of the cultural tourists.

Amongst the abundance of tools available for interaction design, user typologies have been claimed to be “the most effective and fundamental”. By creating a concrete image of the user, designers gain insight into the elements a User Interface (UI) should have and how the user is likely to respond to those elements.

Furthermore, during the past years, cultural interactive experiences are produced in an increased pace to bring back the lost fiction, as well as the functional and ritual nature of the cultural objects. To date, there are various technologies available in cultural environments to support cultural exhibitions directly or indirectly (augmented reality, digital storytelling, serious games, linked open data, context awareness), and every technology used makes an impact on the exhibition or the visitors.

CreativityTalks | Prof. Damián Keller will present us “Creativity in post-2020 music practices”

Given the current concentration of technological resources by a few financial conglomerates and the ongoing attempts to eliminate free-sharing from the internet, music once again provides a stage for social experiments that may have long-lasting effects. Damián Keller expands on the idea that we should apply different strategies to post-2020 music-making from the ones we adopted during the twentieth century. He focus on four emerging and complementary trends in an attempt to identify their creative specificities: telematic art, networked music performance, technologies for music notation and representation, and ubiquitous music. He acknowledges the transitory character of some of these labels and stress the difficulties of defining practices that are strongly tied to technological innovations. Rather than claiming the precedence, the intellectual ownership or the territorial hegemony of any of these terms, he proposes a conceptual map that highlights their applicability to various creative targets.

“Creativity in post-2020 music practices” will be presented by Prof. Damián Keller, on the 19th of May, at 18:00, online on: https://youtu.be/1mfRD8JncvY

The session will be moderated by Prof. Gilberto Bernardes, DEI’s Assistant Professor and Coordinator of the Interactive Music and Sound Design area of the Master in Multimedia.

DEI Talks | “Task scheduling algorithms for fog architectures” by Prof. Celestino Lopes de Barros

Celestino Lopes de Barros is Professor at the Faculty of Science and Technology (FCT) of the University of Cape Verde (Uni-CV) since 2005. Graduated in Informatics in 2006 by the Instituto Superior de Educação, he obtained a Master’s degree in Electronic and Engineering and Telecommunications from the University of Aveiro in 2010. Holds the Certificate in Advanced Studies and has a PhD in Science and Technology from UaB and UTAD since 2021. His areas of interest are Cloud computing and its paradigms. Author of several papers focusing on ‘Job Scheduling in Fog Paradigm’.

Join us on the 11th of May, at 14:30, in room I-105 FEUP, for the presentation of “Task scheduling algorithms for fog architectures”

Abstract:

According to the author’s knowledge task scheduling in fog paradigm is highly complex and in the literature there are still few studies on it. In the cloud architecture, it is widely studied and in many researches, it is approached from the perspective of service providers. Trying to bring innovative contributions in these areas, we propose a solution to the context-aware task-scheduling problem for fog paradigm. In our proposal, different context parameters are normalized through Min Max normalization, requisition priorities are defined through the application of the Multiple Linear Regression (MLR) technique and scheduling is performed using Multi-Objective Non-Linear Programming optimization (MONLIP) technique.

DEI Talks | Fluent API: A software engineering technique with type theoretical implications by Yossi Gil

Joseph (Yossi) Gil is an Associate Professor at the Faculty of Computer Science of the Technion, Israel Institute of Technology. His publications were in diverse areas including distributed systems, image processing,  algorithms, PRAMs and parallel computing, databases, concepts of object oriented programming, numerical algorithms, … His B.Sc. (in physics summa cum laude), M.Sc. (computer science, summa cum laude) and Ph.D. were awarded by the Hebrew University in Jerusalem. Theoretical computer science, especially lower bounds and algorithms were his academic nursery, but he is also very keen on programming in various programming languages. His current research interest is in type systems and applications of machine learning to software engineering and numerical algorithms.

Join us on the 27th of April, at 14:30, in room B016 FEUP, for the presentation of “Fluent API: A software engineering technique with type theoretical implications”.

Abstract:

 A chain of method calls in an OO language, such as a.b().c(d).e(f,g).h().i()… is what the industry calls fluent API. In such a chain, the return value of all but the last invocation, is the receiver of the next invocation. The technique is advertised and used as a powerful software engineering tool. The technique is also used to embed domain specific languages (DSLs), such as SQL, in a host general programming language, such as Java. In this talk, I will present the technique, and the fundamental theoretical questions: How should one design the classes and methods so that fluent API works the way it is supposed to? What is required from the type system of the host programming language to admit certain chains, and forbid others?

The presentation will survey a series of publications showing deep correspondence between type systems and the theory of automata: finite state automata, pushdown automata, etc.

DEI Talks | JUMPING FINITE AUTOMATA by Prof. Alexander Meduna

Prof. Alexander Meduna (born 1957 in Olomouc, Czech Republic ) is a theoretical computer scientist and expert on compiler design, formal languages and automata. He is a professor of Computer Science at the Brno University of Technology. Formerly, he taught theoretical computer science at various European and American universities, including the University of Missouri, where he spent a decade teaching advanced topics of formal language theory. He wrote over ninety papers related to theoretical computer science.

Join us on the 7th April, at 14:30, in room I-105 of FEUP, for the presentation of JUMPING FINITE AUTOMATA

Abstract:

This talk proposes a new investigation area in automata theory — jumping finite automata. These automata work like classical finite automata except that they read input words discontinuously — that is, after reading a symbol, they can jump over some symbols within the words and continue their computation from there. The talk gives several results concerning jumping finite automata in terms of commonly investigated areas of automata theory, such as closure properties. Most importantly, it achieves several results that demonstrate differences between jumping finite automata and classical finite automata. In its conclusion, the talk  formulates several open problems and suggests future investigation areas.

His latest book is Handbook of Mathematical Models for Languages and Computation

Talk | “Interactive Music Analysis using the DFT and Pitch-Class Distributions extracted from MIDI files” by Fabian C. Moss

Fabien C. Moss is a Research Fellow in Cultural Analytics at University of Amsterdam (UvA). Working with large symbolic datasets of musical scores and harmonic annotations, he is primarily interested in Computational Music Analysis, Music Theory, Music Cognition, and their mutual relationship. His research is inherently interdisciplinary and aims to bridge the humanities and the sciences by drawing on methods and concepts from the Musicology and Music Theory, Mathematics, Music Information Retrieval, Data Science and Machine Learning, Music Psychology and Cognition, and the Digital Humanities.

Join us on the 4th of April, at 14:30, in room B015 of FEUP, for the presentation of “Interactive Music Analysis using the DFT and Pitch-Class Distributions extracted from MIDI files

By the author:

“The discrete Fourier transform (DFT) is a cornerstone of digital signal processing and commonly used to extract periodicities in time-continuous signals.

In recent years, however, mathematical music theorists have begun to explore DFT’s potential when applied not to the time but to the pitch-class domain, where the periodicities are given by equal divisions of the octave [1-3]. Earlier this year, we introduced wavescapes [4], a visualization method of hierarchical pitch-class relations in pieces of music.

Building on this work, we are currently developing midiVERTO [5], an interactive web app to analyze MIDI files using the DFT, that allows users to create wavescapes and inspect the dynamics of pitch-class distributions at several hierarchical levels. In my presentation, I will briefly introduce the underlying theoretical work followed by a tutorial on how to use the app for music analysis.

CreativityTalks | Prof. António Sampaio da Nóvoa will be our next guest

There are many “futurisms” that suggest an education without schools, based on the immense possibilities of technologies and artificial intelligence. These “futurisms” gained strength with the pandemic and the different forms of isolation to which we have been subjected. But education does not take place in “confinement”, it always requires a relationship, an encounter, working together. This is not the time to announce the “death of school”, but rather to invent it anew.

“Inventing the School anew” will be the topic of the 6th Creativity Talk, presented by Professor *António Sampaio da Nóvoa, on March 17, at 18:00, at the FEUP’s Anfiteatro Nobre (B032).

The session will be moderated by Amélia Lopes, Full Professor and President of the Scientific Council of the Faculty of Psychology and Education Sciences of the University of Porto.

The participation in the lecture requires a (free) registration at Eventbrite (places available to the capacity of the room by order of registration).
