RESEARCH TOPIC
Multivariate Analysis in Research and Industrial Environments
In the metrological field, the sensor can be identified as the component in direct
contact with the quantity to be measured. As a result of this contact, it can vary one
of its properties, such as electrical resistance or length. This variation can directly
provide the measurement of interest, can be indicated via a common display,
or can be recorded to carry out checks at a later time. Sensors can be classified
according to several factors, including the principle of operation, the application of
interest, the measured quantity, and the output quantity. They can produce large
amounts of data that can reveal hidden links between the data. Visualization is
often used to investigate these properties. The main objective of Antonio's research
is therefore to intuitively and innovatively analyze, visualize, and propose the user
data from different types of sensors. One of the projects he is involved in is the
creation of a system for ground-based, near-real-time recording and display of data
from Fiber Bragg Gratings (FBG) sensors mounted on a model aircraft while it is in
flight. This type of optical sensor can measure temperatures, strains, pressure, and
other quantities. For this reason, interest in it is constantly increasing, especially for
monitoring activities concerning structures in general, human health, environmental
conditions, and more. This project, therefore, aims to further study this sensor in an
unconventional way by recurring to a flying test bench.

RESEARCH TOPIC
Open-Source Framework for Evaluating Database Replication Performance
Database replication duplicates data from a primary database to one or more replica databases. This process
enhances data availability as well as system fault tolerance and reliability. Typically, database replication occurs in
real-time as data is created, updated, or deleted in the primary database. Despite its significance, current approaches
lack a defined paradigm and specific tools for evaluating the performance of database replication. In previous work,
Han focused on assessing the benefits of Read Free Replication (RFR), a feature designed to expedite replication
throughput between MyRocks primary and replica databases.
Building on these findings, Han is leveraging his expertise in software
engineering and database systems to create an open-source framework.
This work enables a more nuanced and customizable measurement of
database replication performance across a variety of database systems.
The research makes three main contributions: 1) a pluggable design that
can accommodate any database system; 2) more customizable workload
definitions compared to existing state-of-the-art (SOTA) approaches; and 3)
a novel paradigm in measuring database replication.
