The four-stroke reduction engine [PDF]

open access: yesProceedings of the 1986 ACM conference on LISP and functional programming - LFP '86, 1986
© 1986 ACM. Functional languages are widely claimed to be amenable to concurrent execution by multiple processors. This paper presents an algorithm for the parallel graph reduction of a functional program. The algorithm supports transparent management of parallel tasks vlth no explicit communication between processors.

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Characteristics of the Limit Cycle of a Reciprocating Quantum Heat Engine [PDF]

open access: yes, 2004
When a reciprocating heat engine is started it eventually settles to a stable mode of operation. The approach of a first principle quantum heat engine toward this stable limit cycle is studied.

Comparative Assessment and Parametric Optimisation of Large Marine Two-Stroke Engines with Exhaust Gas Recirculation and Alternative Turbocharging Systems

open access: yesJournal of Marine Science and Engineering, 2022
Although the exhaust gas recirculation (EGR) technology has been proven effective to decrease the marine engine’s nitrogen oxides (NOx) emissions, it is associated with a considerable fuel consumption increase and challenges to the engine–turbocharger ...
