This research effort starts by developing a descriptive model that is capable of capturing the inherent non-lane-based traffic behavior characteristics of bicycles. In that regard, the research team extends the Fadhloun-Rakha bicycle-following longitudinal motion model through complementing it with a lateral motion strategy;thus allowing for overtaking maneuvers and lateral bicycle movements. For the most part, the following strategy of the FR model remains valid for modeling the longitudinal motion of bicycles except for the activation conditions of the collision avoidance strategy, which are modified in order to allow for overtaking when possible. The proposed methodology is innovative in that it makes use of the intersection of certain pre-defined regions around the bicycles to decide on the feasibility of angular motion along with its direction and magnitude. The resulting model is the first point-mass dynamics-based model for the description of the longitudinal and lateral behavior of bicycles in both constrained and unconstrained conditions. In fact, by having the FR bicycle-following model as the governing module of longitudinal behavior and a dynamic lateral module, the proposed model is found to be both robust and able to model bicyclist behavior variability. Furthermore, it is the only existing model that is sensitive to the bicyclist physical characteristics and the bicycle and roadway surface conditions given that the used longitudinal logic was previously validated against experimental cycling data. Next, this study describes a new framework for the collection of naturalistic cycling data. In that process, a new naturalistic cycling dataset is collected for the purpose of validating the developed bicycle lateral motion model. Given that the collection of naturalistic cycling data is not achievable in the traditional vehicle approach, machine learning and computer vision techniques were used to construct the naturalistic dataset from existing video feeds

The Italian foundation for Security and Rights in Cyberspace (SERICS) is in charge of managing the current, broad range, research in a variety of computer security domains, ranging from strictly computer related aspects, such as OS and Virtualization security, to the development of new cryptographic techniques, up to tackling human, social and legal problems related to computer security and privacy. The SERICS project is founded by the Italian National Recovery and Resilience Plan (NRRP), which in turn receives funding from the EU - NextGenerationEU programme. The SERICS foundation is managing the STRIDE project, to tackle the aforementioned research challenges. In the context of the STRIDE projects, a cascade call was made to tackle specific aspects of the overall reseach challenges. The two-years AQuSDIT project, winner of the aforementioned cascade call, aims to tackle the current open problems in the digital identity realm, with a particular focus on resistance to quantum computer-based attacks, and ledger-based technologies for identification and supply chain tracking. In this context, the research activities at Politecnico di Milano focus on the design of post quantum cryptosystems, and their secure and efficient realization as hardware components, either in the form of full accelerators, or support to existing computing infrastructures. In the following, we will present an overview of the research activities of the 2-year AQuSDIT project, together with an outlook on the first research results which have been obtained by the group of participants from Politecnico di Milano.

Efficient processing architectures for irregular data patterns require vector element addressing with flexible indices. Therefore, state-of-the-art SIMD vector extensions implement gather and scatter instructions for indexed addressing of data in memory. In vertical vector processors, different data is processed sequentially in parallel lanes and can be exchanged via chaining. This paper proposes an extension of such chaining mechanisms in a vertical vector processor architecture (V2PRO) to flexibly chain not only data but also address offsets between vector lanes. The indirect addressing enables vector access patterns with irregular strides for both register file and memory. The extension has a low hardware overhead of +4.8 % lookup tables and +1.8% registers on a Xilinx Ultrascale+ FPGA. A runtime evaluation for two applications from computer vision, namely Deformable Convolutions and point cloud encoding with PointPillars, demonstrates speedups of at least an order of magnitude with the proposed extension.
