Estimation of Combustion Parameters from Engine Vibrations Based on Discrete Wavelet Transform and Gradient Boosting

open access: yesSensors, 2022
An optimal control of the combustion process of an engine ensures lower emissions and fuel consumption plus high efficiencies. Combustion parameters such as the peak firing pressure (PFP) and the crank angle (CA) corresponding to 50% of mass fraction ...

Acute dermal toxicity study of new, used and laboratory aged aircraft engine oils

open access: yesToxicology Reports, 2019
There is little data available on toxicity levels of used aircraft engine oils relative to their unused (new) versions. This study was conducted to determine if new engine oils and their used versions have the potential to induce dermal irritation ...

Reaction Force Analysis for Obstacle-Aided Locomotion of Snake Robot Using Piecewise Helixes

open access: yesIEEE Access, 2023
Snake robots can use numerous joints to move in various manners. One of them is the obstacle-aided locomotion, a method in which a robot moves by pushing obstacles.

A Digital-Model-Based Approach for Defining HIRF Immunity Design Requirements of Commercial Aircraft Engine Control Systems

open access: yesIEEE Access
Commercial aircraft engine control systems must be immune to high-intensity radiated field (HIRF) effects to operate reliably and function stably under electromagnetic (EM) disturbances. However, there is a lack of effective methods to clearly define the

Systems engineering to systems biology

open access: yesMolecular Systems Biology, 2008
Mol Syst Biol. 4: 185 The ‘bottom‐up’ approach to systems biology entails quantitatively studying complex biological processes by analyzing their molecular components. A converse system biology approach is to infer properties of biological systems in a ‘top‐down’ fashion, using a variety of network reverse engineering methods, data‐driven modeling and

Circular systems engineering

open access: yesSoftware and Systems Modeling
The perception of the value and propriety of modern engineered systems is changing. In addition to their functional and extra-functional properties, nowadays' systems are also evaluated by their sustainability properties. The next generation of systems will be characterized by an overall elevated sustainability -- including their post-life, driven by ...

Engineering the Lymphatic System [PDF]

open access: yesCardiovascular Engineering and Technology, 2011
The recent advances in our understanding of lymphatic physiology and the role of the lymphatics in actively regulating fluid balance, lipid transport, and immune cell trafficking has been furthered in part through innovations in imaging, tissue engineering, quantitative biology, biomechanics, and computational modeling.
