Using Deep Learning to Identify Cyclists' Risk Factors in London | PresentationLuís Rita
The aim of this project was to use object detection and image segmentation models to extract cyclists’ road risk factors from GSV images of London. This involved compiling road safety indicators and risk factors; analysing a GSV dataset, before using two state-of-the-art tools, YOLOv5 and PSPNet101, to detect objects and segment images, respectively, and further analysing their results; determining the limitations of YOLOv5, PSPNet101 and suggesting ways of making cyclists’ safety assessment more accurate.
Machine Learning for Building a Food Recommendation SystemLuís Rita
Many factors influence individual’s health, such as physical exercise, sleep, nutrition, heredity and pollution. Being nutrition one of the biggest modifiable factors in our lives, small changes can have a big impact. With the exponential increase in the number of available food options, it is not possible to take them all into account anymore. The only way to consider user taste preferences, maximize the number of healthy compounds and minimize the unhealthy ones in food, is using (3D) recommendation systems.
The goal of this project was to use the largest publicly available collection of recipe data (Recipe1M+) to build a recommendation system for ingredients and recipes. Train, evaluate and test a model able to predict cuisines from sets of ingredients. Estimate the probability of negative recipe-drug interactions based on the predicted cuisine. Finally, to build a web application as a step forward in building a 3D recommendation system.
A vectorial representation for every ingredient and recipe was generated using Word2Vec. An SVC model was trained to return recipes’ cuisines from their set of ingredients. South Asian, East Asian and North American cuisines were predicted with more than 73% accuracy. African, Southern European and Middle East cuisines contain the highest number of cancer-beating molecules. Finally, it was developed a web application able to predict the ingredients from an image, suggest new combinations and retrieve the cuisine the recipe belongs, along with a score for the expected number of negative interactions with antineoplastic drugs (github.com/warcraft12321/HyperFoods).

INSaFLU | Innovation and Entrepreneurship ReportLuís Rita
Along with my master thesis Community Finding with Applications on Phylogenetic Networks, in which a set of visualization and analysis tools were developed, I was enrolled in an internship in Instituto Nacional de Saúde Doutor Ricardo Jorge. Some of the tools implemented during the thesis will be soon introduced in INSaFLU, a web application developed in this institution. Below, the app and the developed modules are detailed.
BIG Smart Cities is one of the biggest entrepreneurship competitions organized in Portugal. This year, it counted with more than 200 projects from all over the world.
Smarty is the name of the project I decided to submit. Mine was the winner in the category of "5G University Challenge".
Besides having received mentoring from Vodafone, Ericsson and Municipality of Cascais, it was given me the opportunity to have an internship in one of the 2 first companies. Plus, a monetary award to accelerate the project.

App: https://play.google.com/store/apps/details?id=appinventor.ai_luis20dr.Smarty2&hl=pt
A remote controlled car and the respective app were developed under the supervision of Prof. Luís Sousa, from Instituto Superior Técnico (University of Lisbon).
[App]
Using MIT App Inventor 2, we developed an Android app that is able to control many features of a RC car, using a Bluetooth connection. Specifically, the angular velocity of the back wheels, the rotation angle of a front servo, a horn, music, light and GPS components.
[Car]
All parts of the RC car were modelled using the CAD software SolidWorks. The complete model was divided in several components (which were meant to be 3D printed separately): wheels, chassis, L-shape axles, connecting bar and the body of the car.

Community Finding with Applications on Phylogenetic Networks [Thesis]Luís Rita
With the advent of high-throughput sequencing methods, new ways of visualizing and analyzing increasingly amounts of data are needed. Although some software already exist, they do not scale well or require advanced skills to be useful in phylogenetics.
The aim of this thesis was to implement three community finding algorithms – Louvain, Infomap and Layered Label Propagation (LLP); to benchmark them using two synthetic networks – Girvan-Newman (GN) and Lancichinetti-Fortunato-Radicchi (LFR); to test them in real networks, particularly, in one derived from a Staphylococcus aureus MLST dataset; to compare visualization frameworks – Cytoscape.js and D3.js, and, finally, to make it all available online (mscthesis.herokuapp.com).
Louvain, Infomap and LLP were implemented in JavaScript. Unless otherwise stated, next conclusions are valid for GN and LFR. In terms of speed, Louvain outperformed all others. Considering accuracy, in networks with well-defined communities, Louvain was the most accurate. For higher mixing, LLP was the best. Contrarily to weakly mixed, it is advantageous to increase the resolution parameter in highly mixed GN. In LFR, higher resolution decreases the accuracy of detection, independently of the mixing parameter. The increase of the average node degree enhanced partitioning accuracy and suggested detection by chance was minimized. It is computationally more intensive to generate GN with higher mixing or average degree, using the algorithm developed in the thesis or the LFR implementation. In S. aureus network, Louvain was the fastest and the most accurate in detecting the clusters of seven groups of strains directly evolved from the common ancestor.

1st Project - Health Systems.
Day after day, health is becoming an increasingly hot issue in our daily life. Particularly, ageing can be thought as one of the primary causes for such an increasing demand and expense in health services. Therefore, it’s not surprising a larger fraction of the countries’ domestic gross product is being allocated to improve care, provided by health authorities, as well as public services, guaranteeing a pleasurable and safe coexistence among people.
One way of achieving such goals, without excessive expenditure, is using decision support models. In one hand, it’s true that forecasting [Request 3], linear programming [Request 4] or a mere construction of a decision tree [Request 2] entails some costs. But, at the end, countries or health services that better apply these mathematical techniques are achieving better results with the same or lower costs.

The Role of Internet-of-Things (IoT) in HealthcareLuís Rita
1st Project - Health Systems.
As a result of ageing population, increasing demand and evolving technology on healthcare systems, the progress in the Internet of Things (IoT) has a key role in suppressing all these needs, in particular, redesigning modern health care with promising technological, economic and social prospects. This paper attempts to comprehensively review the current research and development on the impact of IoT in Healthcare. Relying on a comprehensive literature review, this paper analyses the architecture of an IoT-based systems, focusing on the main components and their value to the overall system. In addition, a perspective on electronic health records and on privacy and security issues are overviewed, along with the review of clinical cases of IoT-based systems. Given IoT clear acceptability and affordability among youngers and elders, combined to a broad range of devices and machine learning techniques, it’s expected these devices will facilitate in many ways health providers’ job, as long as other topics like data protection keep side-by-side.

Homework X - Biomaterials Science.
An extracorporeal artificial organ is a man-made device that is integrated into a human — interfacing with living tissue — to replace a natural organ, for the purpose of duplicating or augmenting a specific function or a group of related functions so the patient may return to a normal life as soon as possible. The replaced function doesn't necessarily have to be related to life support, but it often is.

Mechanisms in Aqueous Solution for Corrosion of Metal AlloyLuís Rita
Homework VI - Biomaterials Science.
Corrosion is a natural process which can be found, not only in metals, but also in ceramics and polymers (instead of corrosion, it is usually called “degradation”). 2 main concerns around this topic include economic and security issues. In fact, big accidents related to corrosion are present in the world’s history... Some involved crashed bridges and sunk ships. Processes to avoid events like this should be carefully chosen, accordingly to our monetary resources, as well as considering the severity of a hypothetical situation where the material can fail (e.g. - if there are any lives at risk).
