To Share or Not to Share: On Location Privacy in IoT Sensor Data
(2022)7TH ACM/IEEE CONFERENCE ON INTERNET-OF-THINGS DESIGN AND IMPLEMENTATION (IOTDI 2022)Data sharing is crucial for building large datasets which in return are essential for developing and training accurate models in many contexts including smart cities, agriculture, and medical applications. However, shared data may leak private information, such as personal identifiers or location. Past research provides evidence that solely removing these identifiers through pseudonymization is not enough to ensure data privacy protection, ...Conference Paper -
DoCile: Taming Denial-of-Capability Attacks in Inter-Domain Communications
(2022)2022 IEEE/ACM 30TH INTERNATIONAL SYMPOSIUM ON QUALITY OF SERVICE (IWQOS)In recent years, much progress has been made in the field of Internet bandwidth reservation systems. While early designs were neither secure nor scalable, newer proposals promise attack resilience and Internet-wide scalability by using cryptographic access tokens (capabilities) that represent permissions to send at a guaranteed rate. Once a capability-based bandwidth reservation is established, the corresponding traffic is protected from ...Conference Paper -
Active learning for system reliability analysis using PC-Kriging, subset simulation and sensitivity analysis
(2022)Structural reliability analysis aims at assessing the safety of structures which often operate under uncertain conditions. Approximation-, simulation- or surrogate-based methods are used in this context to estimate the failure probability. Surrogate-based methods are the least computationally intensive and consist in building a cheaper proxy of the original limit-state function, which is calibrated using a limited set of samples known as ...Conference Paper -
Multi-Criteria Decision Making in Digital Participation: A framework to evaluate participation in urban design processes
(2022)Co-creating the Future: Inclusion in and through DesignData-driven urban design processes consist of iterative actions of many stakeholders, which require digital participatory approaches for collecting data from a high number of participants to make informed decisions. It is important to evaluate such processes to justify the necessary costs and efforts while continuously improving digital participation. Nevertheless, such evaluation remains a challenge due to the involvement of different ...Conference Paper -
Introducing latent variables in polynomial chaos expansions to surrogate stochastic simulators
(2022)Stochastic simulators are computational models that produce different results when evaluated repeatedly with the same input parameters. In this respect, the model response conditional on the input is a random variable, and thus it is necessary to run the model many times to fully characterize the associated response. Due to the large number of necessary model runs, performing uncertainty quantification or optimization of a costly stochastic ...Conference Paper -
The effective width of cross‐laminated timber rib panels in fire
(2022)The composite structure of cross‐laminated timber rib panels consists of cross‐laminated timber (CLT) plates connected to glued‐laminated timber (glulam) ribs. Full composite action is provided by a rigid connection between the composite components by means of screw‐press gluing. For ribbed cross‐sections, the assumption that the cross‐section remains plane is incorrect. The simple beam theory according to Euler‐Bernoulli is not applicable ...Conference Paper -
Robust Control Design for Flexible Guidance of the Aerodynamic Descent of Reusable Launchers
(2023)Rocket reusability is a key-factor for a sustainable and cost-effective future of space missions. Despite successes in this technology, some of the open problems remain an impediment to further development. For example, the descent phase presents important challenges from a guidance and control perspective, because, due to model and environment uncertainty, the optimal re-entry trajectory is often unknown a priori. As a result, the ...Conference Paper -

(2022)RILEM Bookseries ~ Third RILEM International Conference on Concrete and Digital FabricationWhile digital fabrication technologies with concrete have focused primarily on process development and compressive strength in terms of performance, more recently studies evaluating the durability performance of 3D printed cementitious materials have started to appear. To date, however, no field performance assessments have been published regarding 3D printed cementitious materials. In this study, we present the condition of bespoke 3D ...Conference Paper -
Modeling of In-chip Current-Temperature Distribution of SiC Power MOSFETs during Fast Switching Events
(2022)PROCEEDINGS OF THE 19TH INTERNATIONAL SYMPOSIUM ON POWER SEMICONDUCTOR DEVICES AND ICSThis paper presents a modeling approach that allows the prediction of both current and temperature distribution within a SiC MOSFET die during a fast switching event in Spice circuit simulations. It is based on an equivalent model developed including the 3-D gate layout parasitics and a 3-D R-C network for the thermal die model. The gate layout parasitics are modeled by an analytical R-L model extracted from a 3-D layout geometry, so that ...Conference Paper -
Understanding RowHammer Under Reduced Wordline Voltage: An Experimental Study Using Real DRAM Devices
(2022)2022 52ND ANNUAL IEEE/IFIP INTERNATIONAL CONFERENCE ON DEPENDABLE SYSTEMS AND NETWORKS (DSN 2022)RowHammer is a circuit-level DRAM vulnerability, where repeatedly activating and precharging a DRAM row, and thus alternating the voltage of a row's wordline between low and high voltage levels, can cause bit flips in physically nearby rows. Recent DRAM chips are more vulnerable to RowHammer: with technology node scaling, the minimum number of activate-p recharge cycles to induce a RowHammer bit flip reduces and the RowHammer bit error ...Conference Paper -
