Healthcare analytics has attracted increasing research interests as electronic health records (EHR) and medical image data have skyrocketed over the past decade [1]. EHR and lab reports contain rich text, visual, and time series information such as a patient’s medical and diagno…

The wireless industry is growing very fast in the last decade with the main aim of high-speed, low-latency, and reliable communication. Localization, being a primary and essential component of wireless communication, needs to be efficient enough to match modern requirements. Wit…
O presente Relatório Final de Estágio − desenvolvido no âmbito das unidades curriculares de Práticas do Ensino Supervisionada que incorpora em si o Mestrado em Ensino do 1.º Ciclo do Ensino Básico e de Português e História e Geografia de Portugal no 2.º Ciclo do Ensino Básico − …
In today's world, people visit many attractive places. On such an occasion, It is of utmost importance to be accompanied by a tour guide, who is known to explain about the cultural and historical importance of places. Due to the advancements in technology, smartphones today have…
Existem inúmeras minas desativadas que apresentam um elevado valor patrimonial e histórico. Contudo a maioria destas minas acaba por não ser documentadas com o devido cuidado, existindo o risco de deterioração do património com o passar do tempo, pelo que se torna necessária a e…
Bathymetric mapping is an important tool for reservoir management, typically completed before reservoir construction. Historically, bathymetric maps were produced by interpolating between points measured at a relatively large spacing throughout a reservoir, typically on the orde…
While scientists continue to test the boundaries and the ethical limitations of artificial intelligence (A.I.), they create an omnipresent trend of distrust and, more importantly, fear. From 1921 to 2014, A.I. functioned as an undeniable threat in film, literature, and televisio…
In many applications in robotics, there exist teams of robots operating in dynamic environments requiring the design of complex communication and control schemes. The problem is made easier if one assumes the presence of an oracle that has instantaneous access to states of all e…
A reduced control-centric model of a particular behaviour associated with maritime helicopter rotor systems, known as Blade Sailing Phenomenon (BSP), is developed. BSP is a transient aeroelastic phenomenon described by the large undesired flapping motion of the helicopter rotor …
The design and development of embedded hard real-time (RT) systems is one of the most complex software development practices, because of the criticality and timeliness required for these systems. One critical aspect of RT systems is the production of outputs before the specified…
Robots are becoming more and more prevalent today and one of the challenges for robots is navigating around dynamic environments. Dynamic environments are those where a robot has no a priori information and the environmental conditions can change at any time. This can apply to a…
This research studies the passive dynamics of an under-actuated trotting quadruped. The goal of this project is to perform three-dimensional (3D) dynamic simulations of a trotting quadruped robot to find proper leg configurations and stiffness range, in order to achieve stable t…
The Internet provides a free means of communication for a host of applications ranging from email, web surfing, to live audio and video streaming; eliminating the need for dedicated communication lines and thus reducing costs. The objective of this research is to exploit the Int…
This thesis presents a systematic approach to fuzzy-logic modeling and control of complex systems. In the proposed methodology, the fuzzy model of the system and control rules are obtained from input-output data with no need of a priori information. The proposed fuzzy modeling m…
Behavior-based robot control is a relatively new, but accepted, concept for building autonomous robots. Several different kinds of proof-of-concept robots using the so-called subsumption architecture have been demonstrated. These robots have been shown to solve some fairly diffi…
This thesis investigates the development of an animatronic robot with the objective of showing how modern animatronic models created as special effects have roots in models created during the scientific and mechanical revolution of the 17th and 18th centuries. It is noted that a…
Modular approaches are widely used methods in AI and engineering. This approach reduces the difficulty of solving a complex problem by subdividing the problem into several smaller parts, i.e. modules, and tackle each independently. In this dissertation, we show how modular appro…
This thesis describes the use of a Real-Time Evolutionary Algorithm (RTEA) to optimise an Artificial Neural Network (ANN) on-line (in this context “on-line” means while it is in use). Traditionally, Evolutionary Algorithms (Genetic Algorithms, Evolutionary Strategies and Evoluti…
Multiple robot manipulators cooperating in a common manipulation task can accomplish complex tasks that a single manipulator would be unable to complete. To achieve physical cooperation with multiple manipulators working on a common object, interaction forces need to be controll…
