Description:
During the paper manufacturing process, some paper break events can occur. If a break happens, the entire process is stopped, any found problem is fixed and the production is resumed. Resuming the process can take more than an hour, which represents a severe cost for the factory. Even a 5% reduction in the break events will yield a significant cost saving.
The objective of this thesis is the development of suitable techniques to predict such breaks in advance (early prediction) and identify the potential cause(s) to prevent the break. To build such a prediction model, the applicant will use data collected from a network of sensors deployed to monitor a real manufacturing plant.

Description:
Drilling is a complex process that consists in boring a hole (that can be several thousands of meters long) in order to create a well for oil (or gas) production. A sticking occurs when the drillstring cannot be neither rotated nor moved along the axis of the wellbore. A pipe is considered stuck if it cannot be freed from the hole without damaging the pipe, and without exceeding the drilling rig's maximum allowed hook load. This phenomenon can be due to pressure-related issues (if the pressure in the annulus exceeds that in the formation being drilled, the drillstring is pulled against the wall of the borehole and held against it) or to mechanical blocking (e.g., due to incomplete removal of the cuttings, or partial collapse of the borehole). Stuck-pipe phenomena can have disastrous effects on drilling performance, with outcomes that may range from time delays (note that a day of drilling can cost millions of euros) to loss of expensive machinery. This thesis aims at the development (using machine learning techniques) of a data-based prediction model that can be used to anticipate the occurrence of the mentioned events. A large dataset of oil&gas wells can be used to train and validate the model.
This work is part of an ongoing collaboration with Eni's Drilling & Completion Risk Analysis Department.

Description:
Discrete event systems (DES) are characterized by a discrete set of states, and state changes are driven by the occurrence of (asynchronous) discrete events. This is a very general class of models, which is often encountered in automated manufacturing, communication and transportation networks, control applications, etc.
In timed DES the transitions between activities are further endowed with time bounds in order to represent the duration of activities. A timed control task involves reaching specific states (while avoiding others) within prescribed time limits.
The design of a controller for timed DES is a complex and challenging task that requires the development of suitable tools for reachability analysis, path optimization, and control policy design. This thesis aims at the development of a Matlab library of such tools for time Petri nets and its testing on some timed DES control benchmarks.

The thesis will focus on generating chatbots out of a website equipped with simple, bot-specific HTML annotations. The approach is part of what we call conversational web browsing, i.e., a dialog-based, natural language interaction with websites. The goal is to enable users to use content and functionality accessible through visual UIs by “talking to websites” instead of by operating the graphical UI using keyboard and mouse. The project is held in collaboration with associations for visually impaired and low-vision people.

Description:
Chatbots for data exploration support conversations that let the user progressively discover and interactively retrieve data from known data sources. Given the multiple advantages that the literature recognizes to the conversational paradigm for data access, and its current diffusion through different applications, there is now much emphasis on methodologies for chatbot design. A diffused opinion is that domain experts, with their special knowledge and understanding of a specific field, are critical in the development of chatbots; but it also emerges that engaging them in chatbot development is difficult due to their lack of technical competencies. Starting from a conceptual model for the rapid generation of chatbots, the thesis project will focus on the definition of interactive, visual paradigms for the End-User Development (EUD) of chatbots for data exploration.

This project aims to extend the current capabilities of frameworks for chatbot development in the domain of data exploration. Nowadays, chatbot applications are growing in a larger number of sectors and activities. However, it is still unclear how to capitalize on technologies for data access and exploration. The creation of the knowledge base with which the conversational agent will interact and its integration with the dialog system are still considered obstacles. This project aims to understand whether it is possible to extend the capabilities of current technologies to simplify the management of the chatbot knowledge base and fasten the development of chatbots for data exploration through model-based techniques for the automatic generation of the dialog system.

Description:
Social media are a relevant source of information for decision-makers but their extraction and processing can be challenging. In fact, although data is extracted according to specific keywords through a crawler, a huge amount of irrelevant information is present in the resulting data set. These data have to be manually analyzed by human operators, for instance, Crowd workers, for annotating them with needed metadata. In this scenario, filtering out all irrelevant elements is necessary to make the approach feasible. This thesis aims at providing the user a methodology for supporting the definition of a pipeline able to eliminate irrelevant information according to the goal for the analysis to be performed on the data. Given a set of available components for the pipeline, each one is evaluated in terms of its efficiency (precision and recall, execution time, execution cost), and the best combination of components is selected according to the user’s quality requirements.

Description:
Modern applications are composed of several components (microservices, functions, monoliths) that cooperate together for reaching the overall application goal. They can be hosted in different locations in a cloud environment or in the owner facilities, as well as in edge or IoT devices. Most of the existing infrastructures don’t provide information about the energy consumption at the application component level, and even less information about the emissions generated by the application execution. Thus, some models to derive this information are needed if we want to envision a real sustainable application future. The aim of this thesis is to explore the current state of the art and the existing tools for deriving energy consumption of single-component applications and their emissions and to propose a method to extend these tools by enabling the derivation of the overall energy consumption of an application and sustainability impact.

Description:
Sustainability and Energy Efficiency are a driver for the improvement of our society and a necessity for a better future. While Data Centers are getting greener, this is not the case for other computing locations like fog and edge computing, composed of small and inefficient data centers. Considering applications as composed of several microservices interconnected in a workflow and exchanging data, the research question is how it is possible to adaptively deploy each component in a different location by considering the trade-off between QoS and Energy Efficiency. This thesis aims at providing an algorithm for deploying multi-component applications in a heterogeneous dynamic fog environment while minimizing emissions and respecting QoS constraints.

Description:
Sustainability and Energy Efficiency are a driver for the improvement of our society and a necessity for a better future. While Data Centers are getting greener, applications hosted by them are keeping requiring more and more resources. This thesis aims at providing a methodology to design sustainable applications using existing modeling tools and enriching them with additional features and to implement the translation from a sustainable workflow model into an executable workflow using microservice-based applications and an orchestrator. The goal is to provide applications sensitive to their current energy consumption and emissions able to adapt by enacting modifications in their workflow by: i) defining optional and mandatory tasks, ii) defining alternative execution modalities (sustainable or performance-oriented) for the same task, iii) defining rules to activate different versions of the workflow based on the application monitoring data.

Description:
A Fog Environment sees computational resources spread in different locations with heterogeneous capabilities and characteristics. Data is most of the time collected at the edge of the network and moved to the cloud to be stored and analysed. With additional computing power at the edge, computation is moving more and more nearer the data, but some constraints have to be considered. This thesis will investigate the synergy between application deployment and data availability by providing a methodology for adaptively deploying applications in a fog environment while considering resource availability, data location, data quality requirements, and QoS requirements. The methodology aims at reducing the amount of data traveling from the edge to the cloud by proposing an adaptive monitoring system (AMS). The AMS employs Machine Learning techniques to detect correlations between monitoring data and build models to reconstruct missing data directly in the cloud. This thesis will explore different deployments of the AMS components to identify their outcome on the QoS of the monitoring data collection and on the Data Quality of the applications using the data. The goal is to provide a methodology to automatically tuning a monitoring data collection system according to the context of usage of the data.
