The JPEG standardization committee (ISO/IEC JTC1 SC29/WG1) has developed a new part of "JPEG Systems". This Part 4 standardizes some mechanisms for adding privacy and security to standard JPEG images. The DMAG (Distributed Multimedia Applications Group) of the Computer Architecture Department of the UPC has contributed to the specification of this new standard. Most JPEG standards are complemented with "Reference Software", which implements most of the features of the standard in order to demonstrate its feasibility and give hints on how to implement it. The objective of this project is to produce a first draft version of a partial implementation of Reference Software for the new JPEG Privacy and Security (JPEG P&S) specification. Since JPEG P&S is based on the concept of the JPEG Universal Metadata Box Format (JUMBF), specified in the new part 5 of JPEG Systems, it might be necessary to also implement some elements of JUMBF. The results of this work could be contributed to the JPEG standardization committee for its approval.

Companies and scientists working in areas such as finance or genomics are generating enormously large datasets (in the order of petabytes) commonly referred as Big Data. How to efficiently and effectively process such large amounts of data is an open research problem. Since communication is involved in Big Data processing at many levels, at the NaNoNetworking Center in Catalunya (N3Cat) we are currently investigating the potential role of wireless communications in the Big Data scenario. The main focus of the project is to evaluate the impact of applying wireless communications and networking methods to processors and data centers oriented to the management of Big Data. OBJECTIVES =========== N3Cat is looking for students wanting to work in the area of wireless communications for Big Data. To this end, the candidate will work on one of the following areas: - Traffic analysis of Big Data frameworks and applications, as well as in smaller manycore systems. - Channel characterization in Big Data environments: indoor, within the racks of a data center, within the package of CPU, within a chip. - Design of wireless communication protocols for computing systems from the processor level to the data center level.

Machine Learning (ML) has taken the world by storm and has become a fundamental pillar of engineering. As a result, the last decade has witnessed an explosive growth in the use of deep neural networks (DNNs) in pursuit of exploiting the advantages of ML in virtually every aspect of our lives: computer vision, natural language processing, medicine or economics are just a few examples. However, NOT all DNNs fit to all problems: convolutional NNs are good for computer vision, recurrent NNs are good for temporal analysis, and so on. In this context, the main focus of N3Cat and BNN-UPC is to explore the possibilities of the new and less explored variant called Graph Neural Networks (GNNs), whose aim is to learn and model graph-structured data. This has huge implications in fields such as quantum chemistry, computer networks, or social networks among others. OBJECTIVES =========== N3Cat and BNN-UPC are looking for students wanting to work in the area of Graph Neural Networks studying their uses, processing architectures, and algorithms. To this end, the candidate will work on ONE of the following areas: - Investigating the state of the art on this area, surveying the different works done in terms of applications, processing frameworks, algorithms, benchmarks, datasets. This can be taken from a hardware or software perspective. - Helping to build a testbed formed by a cluster of GPUs that will be running pyTorch or Tensorflow. We will instrument the testbed to measure the computation workload and communication flows between GPUs. - Analyzing the communication workload of running a GNN either in the testbed or by means of architectural simulations. - Developing means of accelerating GNN processing in software (e.g., improving scheduling of the message passing) or hardware (e.g. designing a domain-specific architecture).

In multiple information technology scenarios, it is of interest to be able to specify who is allowed to perform a given action, and under which circumstances. XACML is a way to represent this type of rules in an XML file: it defines policies applying to specified resources which are evaluated against requests. There are multiple implementations of XACML, but none is available as an open-source C or C++ native library: they are only available in JAVA or Python, thus adding overhead when attempting to use XACML from a C/C++ project. This project aims at implementing XACML in C or C++ (C++ is advised). As the entire XACML specification is likely a too large target, the project will focus on what is specified as the core. The student will use the specification as starting point for the implementation, and the use of the existing libraries' source code as a guideline is strongly encouraged and advised. Experience in C++ is required (or C if the student so prefers). This project will have a very important software engineering aspect, and will require to be carefully tested. A decision can be taken to further restrict the scope of the project: e.g. functions such as add time to a date can be skipped, as long as it is clear that the project architecture could support it, and implementing it would be only a time issue. Through this project, the student will be able to show skills, and gain experience, in software engineering and test driven development alongside proving the ability to work autonomously.

Mesh networking with LoRa nodes Meshtastic (https://www.meshtastic.org/) is an open source project which builds a mesh network between LoRa nodes. The LoRa nodes are coupled via Bluetooth to an Android application which implements a messaging service. Text messages are spread over the LoRa network to the other Meshtastic nodes. This is a good place to start reading: https://meshtastic.letstalkthis.com/ We have a couple of TTGO ESP32 LoRa nodes (e.g. http://www.lilygo.cn/prod_view.aspx?TypeId=50003&Id=1271&FId=t3:50003:3) on which Meshtastic can be flashed. Code and further information can be found here: https://github.com/meshtastic/Meshtastic-device More advanced topics: https://github.com/meshtastic/Meshtastic-device/blob/master/docs/software/mesh-alg.md Depending on the scope of the project, the initial work could focus getting familiar with microcontrolers and install and deploy a testbed of a few Meshtastic nodes. Some evaluations and an assessment could be carried out. More advanced work could look at the design of the mesh protocol in Meshtastic, analyze design parameters and propose and evaluate changes/alternative options. If there is a strong interest in the topic, the project could be connected to the work on LoRa mesh networking by Roger Pueyo, member of our research group (https://futur.upc.edu/RogerPueyoCentelles), . https://www.sciencedirect.com/science/article/abs/pii/S0167739X20306063 Note: We have also a gateway connect to The Things Network https://www.thethingsnetwork.org/

The aim of the project is to study the properties of quantum particles in an external field reproducing a fractal structure. A possible realization is an ultracold quantum gas confined to two dimensions with a superimposed external field, which will create the fractal geometry. As a model for the fractal, we will consider Sierpi¿ski carpet. The main properties of interest in the ground state energy and the density profile. Such properties are to be calculated as a function of the recursion number and a possible existence of a simple scaling law has to be verified.

Web tracking technologies are extensively used to collect large amounts of personal information (PI), including the things we search, the sites we visit, the people we contact, or the products we buy. Although it is commonly believed that this data is mainly used for targeted advertising, some recent works revealed that it is exploited for many other purposes, such price discrimination, financial credibility, insurance coverage, government surveillance, background scanning or identity theft. The main objective of this project is to apply network traffic monitoring and analysis technologies to uncover the particular methods used to track Internet users and collect PI. This project will be useful for both Internet users and the research community, and will produce open source tools, real data sets, and publications revealing most privacy attempting practices. Some preliminary results of our work in this area were recently published in Proceedings of the IEEE (IF: 9.237) and featured in a Wall Street Journal article.

Machine Learning with TinyML TinyML aims to do machine learning on microcontrolers. Microcontrolers are sometimes the only choice when the power supply is limited, e.g. in for battery-operated applications. Application examples are "wildlife" observation, such as: https://mybirdbuddy.com/ https://opencollar.io/ Arduino Uno and Mega boards are well known for all kinds of hobbyist microcontroler projects, but there is another kind of more powerful 32 bit microcontrolers and develpment boards, which are able to run machine learning applications. To get the first information on this topic have a look at TensorFlow Lite for Microcontrollers: https://www.tensorflow.org/lite/microcontrollers We have a couple of the mentioned boards like the Arduino Nano 33 BLE Sense, STM32F746 Discovery kit and Espressif ESP32 microcontrolers which can be used for this project. The project will in a first phase explore with practically example applications the topic and do some reading to get a basic understanding of the background. Then the second phase can be shaped accroding to the interest: The project could either develop and deploy a specific applications of interest or focus on analyzing and experimenting a specific step of the machine learning (ML) pipeline which starts at data acquisition and building a machine learning model until doing the deployment and evaluating the application. Other ideas can be suggested, also the integrating an ML-component running on a microcontroler into a distributed application can be discussed. You can find several TinyML examples in Tensorflow, medium or towardsdatascience webs, which people have already tried with code in github repositories e.g. https://codelabs.developers.google.com/codelabs/ai-magicwand/#0 https://www.digikey.es/en/maker/projects/intro-to-tinyml-part-1-training-a-model-for-arduino-in-tensorflow/8f1fc8c0b83d417ab521c48864d2a8ec https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7

The identification of the applications behind the network traffic (i.e. traffic classification) is crucial for ISPs and network operators to better manage and control their networks. However, the increasing use of encryption and web-based applications makes this identification very challenging. This problem is exacerbated with the widespread deployment of content distribution networks (e.g. Akamai) and cloud-based services (e.g. Amazon AWS). The goal of this project is to develop a traffic monitoring tool to accurately identify web services from HTTPS traffic, including Google, YouTube, Facebook, Twitter among others. The tool will combine the information from IP addresses and DNS, with novel classification methods inspired on the Google PageRank algorithm to identify encrypted traffic, even if served from Akamai, AWS or Google infrastructures. This project will be carried out in collaboration with the tech-based company Talaia Networks (https://www.talaia.io), which develops cloud-based network monitoring solutions.

One of the unusual effects observed in non-linear optics is a self-focusing leading to creation of stable propagating wave in a shape of a soliton. A similar state, known as a bright soliton, can be created in ultracold atomic gases in a tight waveguide for attractive interaction between bosons. Such states are commonly described within the mean-field theory in terms of a one-dimensional non-linear Gross-Pitaevskii equation. This equation permits an explicit solution for the bright soliton which is applicable when the interactions between particles are weak. For arbitrary interaction strength there is an exact solution by McGuire describing a one-dimensional system with a contact interaction. Nevertheless, a full description of the soliton as a three-dimensional object confined to a waveguide is still missing. This project aims at providing a full three-dimensional description of a bright soliton in a waveguide by means of Variational and Diffusion Monte Carlo methods.

In a recent experiment (https://arxiv.org/abs/2002.10475) with ultracold dysprosium atoms, it was possible to realize a dipolar gas in one-dimensional geometry at low temperature. The goal of the project is to provide realistic simulation of such a system. To do so, quantum Monte Carlo code has to be developed.
