Title: EmTDLab innovative systematic search for the next-gen radiation shielding materials
Abstract: In the context of the 'New Space' era, space radiation emerges as the predominant constraint for spacecraft operations. This is primarily due to the considerable human health and electronics risks associated with exposure to the space radiation environment. The radiation environment in the Solar System is a complex mixture of particles of solar and galactic origin with a broad range of energies. The three most relevant sources are Galactic Cosmic Rays (GCRs), Solar Particle Events (SPEs) and secondary radiation generated from the interaction of the incoming external radiation with any material (e.g., the spacecraft hull). Current radiation shielding solutions are inefficient from an economic and technical point of view. However, as the research community deepen his knowledge in physics and chemistry, it paves the way for integrating computational intelligence within material science. Moreover, the emergence of advanced computational architectures, coupled with systems and methodologies tailored to harness this power, strengthens the case for computational materials science, also known as materials informatics.
EmTDLab is the sole company researching and designing a computational system for the systematic discovery of novel ionizing radiation shielding materials. The core challenge in materials science lies in identifying materials with optimal properties. Historically, we've been restricted to experimental discovery, bound by the constraints and costs of a trial-and-error method. When it comes to shielding materials against particle radiation, only a limited number of materials have been explored and crafted for electronics component and humans’ protection and shielding in manned spacecraft. Until recently, the development andoptimization of both single and multilayer material configurations have been largely empirical, incrementally optimised over decades. However, the advent of the computational materials science revolution is reshaping our approach. Systematic searches and optimization strategies set the stage for devising materials based on their desired properties. Specifically, EmTDLab employs systematic computational searches through evolutionary algorithms. Beginning with atomic elements, these are iteratively paired with other elements to create material compounds. The material design will lead to a given material composition (single layer shield) or a set of compositions (multi-layer) that takes the primary incoming radiation beam of a specific exposure as an input, and that provides the radiation shielding efficiency of the specific configuration under study. The identified optimal simulated candidate materials can subsequently be synthesized and large-scale manufactured. Applying such a systematic material search techniques to discover new radiation shielding materials has never been undertaken.

Title: Social Bots Detection: Social network analysis approach
Abstract: With the growth of social networking websites, social media has become a major platform for marketing, such as social business, political manipulation, influence and brand management, etc. However, social media marketing is very different from traditional marketing. Social media marketing needs to face many users and repeat the same process frequently. It is therefore a very human power-consuming task. This situation is the reason why Robotic Process Automation and Social-bots is now very popular on many social networking websites. However, there are many negative effects when applying social-bots for social marketing. For example, it may affect political and election results, spread misinformation and fake news speedily, lower the trust of social networking websites and cause cyberbullying, etc. Therefore, in addition to those social networking websites, more and more researchers are devoting to proposing efficient ways to detect social-bots. In this talk, I will introduce Social-bots and the approach to detect social-bots.

Title: Social Economics Analytics: Leveraging Socio-economic Data for the Nation Wellbeing
Abstract: The Sustainable Development Goals (SDGs), also known as the Global Goals, were adopted by the United Nations in 2015 as a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity. The aim of research to achieve the SDG covers the creativity, know-how, technology and financial resources from all of society, which is necessary to achieve the SDGs in every context. The availability of the vast amount of socio-economics data that covers various aspects and profiles is a valuable treasure that contributes to knowledge and decision-making. Socio-economic analytics is an effort to combine research and development of big data analytics in fields involving the well-being of the people and the country to improve society with high impact. The data-intensive technology such as AI and machine learning allows people to get solutions according to personal needs, profiles and activities. It utilizes various related data sources such as economic, social, health, education, and transportation data by exploring essential knowledge that will help those responsible for making decisions, enacting policies and planning initiatives that can improve living standards and incomes and reduce the cost of living for the people. The ultimate goal of achieving the 'No Poverty'' SDG is to improve the living standards for the nation's income groups towards zero poverty. The government initiatives in handling socio-economics problems could be identifying the targeted group based on certain specific indicators, developing appropriate Multidimensional Poverty Index (MPI) indicators, and setting up initiatives for financial literacy among household income classes.
The socio-economics analytics use cases employing well-known and advance Machine Learning algorithms for predictive model development are presented. The model uses datasets related to household income, expenditure, and poverty obtained from several sources at the national level. (1) Households Financial Burden Risk Prediction Model (determiningn the factors that contribute to the risk of the financial burden of a household, patterns of households with financial burden from different income groups, and states.). (2) Gendering Analytics (determining gender-based factors contributing to households' financial risk or non-risk and finding patterns of households with financial risk). (3)Multidimensional Poverty Indicators (MPI) based on machine learning (identifying the appropriate indicators and dimensions that will provide data-driven MPI measurement employing feature fusion and ensemble learning). (4) Clustered-based Multidimensional Poverty Indicators (MPI) to identify the appropriate indicators and dimensions for data-driven MPI measurement. (5) Households Spending Behaviour Model for Income Class (finding factors that affect the spending patterns among the household to develop a household overspending model using machine learning. (6) Model of Risk to Retain and Potential to Exit from the low-income group of households. The use cases are based on the three preliminaries: source of data, data preparation and labeling baselines, and machine learning algorithms used for predictive model development. The standard processes in predictive model development employed are data preprocessing and preparation, model development, model evaluation and deployment. Finally, we present the challenges and way forward for socio-economics analytics towards the ensemble algorithms for decision analytics.

Title: Swarm Intelligence for Shape Reconstruction in the Context of the European Project PDE-GIR: Recent Advances and Future Trends
Abstract: Shape reconstruction plays a crucial role in various domains, including computer graphics and animation, computer vision, and image processing. It involves the capture or recovery of the shape and appearance of real-world objects from diverse inputs, which can be geometric (such as a cloud of scanned data points), visual (a single image or a collection from multiple viewpoints), or a combination of both. However, this process is widely recognized as challenging and computationally expensive.
Addressing this challenge is a key objective of the MSCA European project PDE-GIR. This project aims to explore innovative methods, particularly leveraging partial differential equations (PDE), either independently or in conjunction with other techniques, to tackle complex instances. A promising avenue being explored involves the integration of PDE with artificial intelligence (AI) methods, which have gained significant attention in recent years due to remarkable developments in the field of AI, including deep learning, generative AI, real-time object detection, biometric recognition, and more, which are reshaping the current landscape of today’s digital world in ways that were unimaginable just a few years ago.
One of the most remarkable AI approaches is swarm intelligence, a groundbreaking computing technology with applications spanning academic and industrial fields. Swarm intelligence systems consist of simple agents that interact locally with each other or their environment, exhibiting basic behavioral patterns and operating autonomously in a decentralized and self-organized manner. Despite the simplicity of individual agents, their local interactions give rise to a collective intelligence, enabling the swarm to perform sophisticated tasks and develop complex behavioral patterns unattainable to the individual agents.
This presentation will explore some of the most recent advances achieved in the PDE-GIR project, concluded at the end of October 2023, focusing on the application of swarm intelligence methods to shape reconstruction. The discussion will encompass diverse academic, professional, and industrial domains, including computer-assisted design and manufacturing, computer animation, computer vision, medical imaging, and swarm robotics. Additionally, the presentation will touch upon future trends and potential avenues for further research in this exciting field.
