DEI TALKS | “Architectures for building Extraordinary Software” with Joseph Yoder, Graziela Simone Tonin, Neil Harrison and Filipe Correia

Posted on

When building complex systems, it can be all too easy to primarily focus on features and overlook software qualities, specifically those related to the architecture. Pressure to adapt to and shape the market requires organizations to add new features, accommodate new interactions, and have new teams work on adapting the software. Some believe that by simply following Agile practices—starting as fast as possible, keeping code clean, and having lots of tests—a good architecture will magically emerge. While an architecture will emerge, if there is not enough attention paid to the architecture and the code, technical debt, and design problems will creep in until it becomes muddy, making it hard to deliver new features quickly and reliably. Sometimes a straightforward software architecture that starts out small when communication is easy can support guided, incremental architectural changes and can gradually evolve with its environment, remaining fit for its purposes. Other times it is not so simple: the initial software architecture can be poorly suited for supporting required changes, or the accumulation of suboptimal architectural decisions (also known as architectural technical debt) can be too severe. It is essential to have a sustainable architecture that can evolve through the project life-cycle. Sustainable architecture requires ongoing attention, especially when there are evolving priorities, a lot of technical risks, and many dependencies. This will be a roundtable spirited discussion by invited panelists and participants discussing architectural considerations for designing systems, specifically on architectures for building excellent software.

“Architectures for building Extraordinary Software” will be presented February 7, 15:00-16:15, in room B033 and will be moderated by Carlos Duarte (DEI).

Abstract:
“Across all sectors of our society, efficiency is an increasingly paramount concern for a sustainable world. While the significance of efficiency spans all levels, it is at a large scale where the impacts of efficient practices are most prominently noticed. Industrial activities are an example of how efficiency traduces in visible results. It doesn’t require extensive reasoning to recognize that everyday increasingly affordable goods we consume are a direct outcome of these efficiency demands. The market is demanding new services and business models that center the end user in the product design. In the near future, consumers will be able to customize a product on-line, place a production order, and see it delivered, all in the same day. This remarkable possibility arises from of a combination of efficiency and flexibility within the production processes. Several names have been used to describe the same fundamental paradigm in both academic and industrial contexts: Factories of the Future, Smart Manufacturing and Industry 4.0, all remounting to the same technological advent. This concept has far-reaching implications, extending its influence across multiple technological domains, presenting a wealth of research opportunities and driving the need for innovative technologies. This thesis delves into two technological domains related with this new paradigm and tackles one key problem in either domain. Within the Cyber-Physical Production Systems (CPPS) domain, it addresses the problem of establishing a unified network of industrial assets where software and its connections to other assets are clearly discernible and recognized. On the Reconfigurable Manufacturing Systems (RMS) domain, it addresses the fast pace at which the production lines will have to reconfigure, in particular, how software will have to reconfigure in parallel with the production lines and the ease with which new software can be developed and deployed to meet emerging challenges. A solution to both problems emerges from the field of Component-Based Software Engineering (CBSE), where this thesis drew inspiration to develop an innovative Smart Component with enhanced software reconfiguration and deployment capabilities. The proposed system exploits using Linux, a general-purpose operating system, as the component runtime environment (RTE). A combination of shared memory for efficient component communication and parallel and reconfigurable computing properties for enhanced throughput allows the proposed system to meet established application performance standards while maintaining a high degree of flexibility and reusability. The Smart Component’s flexibility is demonstrated through the implementation of two component models. The IEC 61499 component model, designed to model event-driven distributed applications for industrial system monitoring and control, and the Smart Object Self-Description (SOSD), developed by the author to describe software components, their interconnections, and their associations with industrial assets. The IEC 61499 implementation was directly compared to existing RTEs, outperforming them in real-world use cases and equaling the performance of one RTE in a literature benchmark. Additional benchmarks to assess the Smart Component’s reconfiguration performance and simplified software component development method were proposed in this thesis. The effectiveness of the SOSD implementation was validated through its application in a real-world use case, furnishing other CPPS nodes with context regarding the origin of the collected data and the software components responsible for its processing. By using Linux as the RTE, a software layer traditionally dedicated to manage components was deemed unnecessary, due to the system’s ability to execute applications conforming to relevant performance standards, while showing superior software flexibility, and even outperforming existing RTEs which employ the traditional approach. Many runtime environments for software components exist, but few allow the deployment of components built in more than one programming language, and none – to the best of the author’s knowledge – allow the development of components in any language – provided that language is at least able to read and write to files. The simplicity of developing regular software program for Linux and converting it into a software component is a promising feature that should benefit the development of industrial control and monitoring applications by bringing along the benefits of multiple high-level programming languages.”

DEI TALKS | “Analyzing and Modeling Intelligent Systems Users’ Behavior in Digital Society” by Prof. Humberto Marques-Neto

Posted on

“Information systems are ever-increasingly intelligent and present in the daily lives of people and companies, facilitating and modifying the performance of various activities. In addition to handling each system’s intrinsic data, data from its users’ interactions can contribute to identifying, modeling, and analyzing people’s behavior patterns. The data analysis from the usage of web systems and mobile applications and, in particular, from online social networks such as Twitter, Facebook, WhatsApp, Instagram, and TikTok (obviously respecting the privacy of users) can contribute to the understanding of some dynamics and specific behaviors of human beings.

In this talk, I will present how our research group has done the characterization, analysis, and modeling of the behavior of users of intelligent information systems, more specifically, users of online social networks and information systems that make information available in open data portals, to induce the development of new software that use machine learning and artificial intelligent algorithms. The information systems user behavior, together with patterns of social interaction and human mobility in urban centers, in addition to subsidizing decisions and policies of government agencies and institutions responsible for urban planning, could foster and even target software developers interested in creating innovative software with the potential to improve people’s lives in a digital and connected society.”

“Analyzing and Modeling Intelligent Systems Users’ Behavior in Digital Society” will be presented January 25, at 14:00, room B006, moderated by Prof. Gil Gonçalves (DEI).

The thesis was co-supervised by Doutor Nuno Lau, Associate Professor at the University of Aveiro.

Abstract:
“This thesis studies the balance problem in game development, notably in two-player games. Specifically, we aim to study the viability of Artificial Intelligence (AI) as an assisting tool to fix game properties. We split our research into two paths: Power Balance, where the aim is to adjust game strategies, so they become effective as winning tools; Difficulty Balance, where the objective is to adjust game attributes on the fly so that weaker players or players at a disadvantage can compete with stronger players or players in advantage. Both domains require tuning the game, but they mainly differ in the timing and in their aim, one deals with the imbalance in game design, while the other deals with inequality in player skills. For Power Balance, our methodology was to define a full meta-game balance ecosystem based on the Pokémon video game franchise and develop an AI competition where the multiple associated tasks (battling, team prediction and assembly, and meta-game balance) are present and can be tested in a common ground. To balance the meta-game, we follow an adversarial model where team builders aim to narrow the use of optimal Pokémon while balancer agents aim to incentive the maximum of Pokémon as possible to be selected by team builders. This results in agents being able to play, build effective teams, and being able to tune the Pokémon roster over time. We discuss how our models can be extended to other video game domains. For Difficulty Balance, we propose a Multiplayer Dynamic Difficulty Adjustment framework where a Game Master (GM) agent is trained and embedded into a game, depending on the game state it will deploy handicap mechanisms. The training regime follows a specific pipeline. To generalize advantage situations, parameterized perturbations on the actions of a reference player are used to emulate several degrees of playing skill, and the advantage for each player is used to draw curves which are evaluated as a reward for the GM. This results in the GM being able to optimize game design criteria and create opportunities for the player behind to recover. We show there are suited AI tools for each task, and it is reasonable to think of power balance and difficulty as separate problems, where both can be automatically assisted and eased. Both further augment our overall comprehension of the automated game balance field.”
