Inter-operator reliability of the total decomposition score (TDS) method for estimating the post-mortem interval (PMI) in outdoor cases

In the estimation of the Post-Mortem Interval (PMI), semi-quantitative methods have been proposed to overcome the challenges associated with determining the time of death. Among these, the Total Decomposition Score (TDS) method, developed by Gelderman et al., offers a systematic and semi-quantitative approach for estimating PMI. The aim of this study was to evaluate the reliability of the TDS by assessing its interoperator variability and comparing the results obtained with known reference da...

LES Modelling of Spark-Ignition Cycle-to-Cycle Variability on a Highly Downsized DISI Engine

The paper reports an activity aiming at characterizing cycle-to-cycle variability (CCV) of the spark-ignition (SI) process in a high performance engine. The numerical simulation of spark-ignition and of early flame kernel evolution are major challenges, mainly due to the time scales of the spark discharge process and to the reduced spatial scales of flame kernel. Typical mesh resolutions are insufficient to resolve the process and a dedicated treatment has to be provided at a subgrid level if...

CFD Simulation of Combustion in an Optically Accessible Hydrogen Engine: Comparison between Lean and Diluted Stoichiometric Operations

The reduction of CO2 emissions from anthropogenic activities is pushing the green energy transition, prompting the search for alternative and more environmental-friendly solutions compared to traditional technologies based on fossil fuels. One of the most affected sectors is transportation, which is undergoing a significant change to increase sustainability. To achieve this goal, development of hybrid and electric propulsion systems has taken hold over the past decade, but electrification is ...
