The Prediction of Spark-Ignition Engine Performance and Emissions Based on the SVR Algorithm
Processes, 2022 Engine development needs to reduce costs and time. As the current main development methods, 1D simulation has the limitations of low accuracy, and 3D simulation is a long, time-consuming task. Therefore, this study aims to verify the applicability of the

Skeena: Efficient and Consistent Cross-Engine Transactions [PDF]
Proceedings of the 2022 International Conference on Management of
Data, 2021 Database systems are becoming increasingly multi-engine. In particular, a main-memory database engine may coexist with a traditional storage-centric engine in a system to support various applications. It is desirable to allow applications to access data in both engines using cross-engine transactions.

Wear Resistance of Spark Ignition Engine Piston Rings in Hydrogen-Containing Environments
Energies, 2021 We describe the external and internal hydrogen interaction on contacting surfaces in the “cylinder–piston rings” friction coupling. Under the influence of high temperatures and pressure, the oil in the combustion chamber at a temperature up to 1473 K ...

Design of spark ignition engine speed control using bat algorithm
International Journal of Electrical and Computer Engineering (IJECE), 2021 The most common problem in spark ignition engine is how to increase the speed performance. Commonly researchers used traditional mathematical approaches for designing speed controller of spark ignition engine. However, this solution may not be sufficient.

Social Engineering in Cybersecurity: A Domain Ontology and Knowledge Graph Application Examples [PDF]
Cybersecurity 4, 31 (2021), 2021 Social engineering has posed a serious threat to cyberspace security. To protect against social engineering attacks, a fundamental work is to know what constitutes social engineering. This paper first develops a domain ontology of social engineering in cybersecurity and conducts ontology evaluation by its knowledge graph application.

The Risk-Taking Software Engineer: A Framed Portrait [PDF]
, 2023 Background: Risk-taking is prevalent in a host of activities performed by software engineers on a daily basis, yet there is scant research on it. Aims and Method: We study if software engineers' risk-taking is affected by framing effects and by software engineers' personality.
