This thesis contributes to the International Economics by considering how the openness of an economy and the linkages with other countries matter for the local economic growth. The first strength and the fil rouge of this study is the use of the economic complexity as a measure to identify the strategic sectors that generate larger spillovers and benefits to the economy. Secondly, the use of...

Blockchains are a new type of state machine replication that have raised interesting challenges. A replicated state machine (RSM) is a well-established approach to building fault-tolerant systems. Because each replica needs to execute the same set of instructions to transition through the same state changes, adding more replicas does not translate directly to an increase in performance. On top...

Recent trends in industry show increasing adoption of Development and Operations (DevOps) practices. Reasons for increasing DevOps adoption are the focus on the creation of cross-functional teams, and the ability to release high-quality software at a fast pace. Alongside the adoption of DevOps, performance testing continues to evolve to meet the growing demands of the modern enterprise and its...

These last decades have witnessed an explosion of data collection and diffusion in all fields of human society. In many scientific fields researchers are becoming aware of a big data problem and of the need to manage it properly, combining the tools offered by statistics, computer, data science and informatics. This is particularly true for geo-located data, which can be collected in a...

The field of scientific computing is associated with the modeling of complex physical phenomena. The resulting numerical models are often described by differential equations, which, in many cases, can be related to non-convex minimization problems. Thus, after discretization, the solution of large-scale non-convex optimization problem is required. Various iterative solution strategies can be...

Digitalization is all around us, even more so in pandemic times where substantial part of our lives has been moved online. One of the key enablers of digitalization are the Application Programming Interfaces (APIs) which enable the communication and exchange of data between different systems. They abstract from the implementation details of the underlying systems and allow for the monetization...

Stochastic Optimization Problems take uncertainty into account. For this reason they are in general more realistic than deterministic ones, meanwhile, more difficult to solve. The challenge is both on modelling and computation aspects: exact methods usually work only for small instances, besides, there are several problems with no closed-form expression or hard- to-compute objective functions....

Deep neural networks learn representations of data to facilitate problem-solving in their respective domains. However, they struggle to acquire a structured representation based on more symbolic entities, which are commonly understood as core abstractions central to human capacity for generalization. This dissertation studies this issue for visual reasoning tasks. Inspired by how humans solve...

The immune system has a critical role in diseases of primary importance such as infections and cancer. Hence, it represents a target for novel therapeutic strategies. However, the immune system relies on a complex network of cell-to-cell interactions which remains largely unknown, or difficult to be interpreted. The combination of experimental data with computational methods is of paramount...

Tourism and culture are strongly intertwined. People can experience culture before, during and after their journey, both in the offline and in the online world. Arguably, the internet is among the main sources of inspiration and information retrieval for tourists, who navigate social media and websites to know more about the destination, its products and services. Following the developments in...
