A Study of Rocket Exhaust Particles [PDF]

open access: yes, 1996
The exhaust -plumes generated by rocket motors are of significant military importance for missile detection, recognition and communication due to their electromagnetic emission and propagation properties. The plume is a high temperature, high velocity

Characterization of Particle Number Setups for Measuring Brake Particle Emissions and Comparison with Exhaust Setups

open access: yesAtmosphere, 2023
The stringency of vehicle exhaust emissions regulations resulted in a significant decrease in exhaust particulate matter (PM) emissions over the years. Non-exhaust particles (i.e., from brakes and tyres) account for almost half or more of road transport ...

Identification and quantification of particulate tracers of exhaust and non-exhaust vehicle emissions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
In order to identify and quantify key species associated with non-exhaust emissions and exhaust vehicular emissions, a large comprehensive dataset of particulate species has been obtained thanks to simultaneous near-road and urban background measurements

Environmental Analysis of Petrol, Diesel and Electric Passenger Cars in a Belgian Urban Setting

open access: yesEnergies, 2016
The combustion of fossil fuels in the transport sector leads to an aggravation of the air quality along city roads and highways. Urban air quality is a serious problem nowadays as the number of vehicles increases on a yearly basis.

Research progress on the influencing factors of polycyclic aromatic hydrocarbons and derivatives from vehicle exhaust and non-exhaust emissions

open access: yes工程科学学报, 2023
Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic organic compounds from vehicle emissions. Many PAHs are carcinogenic, teratogenic, mutagenic, and immunotoxic, causing a negative impact on human health and severe damage to the environment and

Non-Exhaustive, Overlapping Clustering

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
Traditional clustering algorithms, such as K-Means, output a clustering that is disjoint and exhaustive, i.e., every single data point is assigned to exactly one cluster. However, in many real-world datasets, clusters can overlap and there are often outliers that do not belong to any cluster.
