Impact of Permanent Magnet Field on Inductance Variation of a PMLSM [PDF]

open access: yes, 2007
Analytical models of Surface Mounted Permanent Magnet Linear Synchronous Motors are generally presented with constant inductances. However, the impact of powerful rare-earth PMs in the saturation phenomena cannot be neglected anymore.

An Experimental Comparison between an Ironless and a Traditional Permanent Magnet Linear Generator for Wave Energy Conversion

open access: yesEnergies, 2022
Permanent Magnet Linear Generators (PMLGs) are currently being studied for sea wave energy harvesting. Typically, a PMLG consists of an iron-made armature and a moving translator. The permanent magnets adoption produces parasitic effects, such as cogging

The linear abstract machine

open access: yesTheoretical Computer Science, 1988
Linear logic [\textit{J.-Y. Girard}, ibid. 50, 1-102 (1987; Zbl 0625.03037)] provides a refinement of functional programming and suggests a new implementation technique, with the following features: - a synthesis of strict and lazy evaluation, - a clean semantics of side effects, - no garbage collector.

Synchronized product of linear bounded machines [PDF]

open access: yes, 1999
This paper introduces a class of graphs associated to linear bounded machines. It is shown that this class is closed, up to observational equivalence, under synchronized product. The first-order theory of these graphs is investegated and shown to be undecidable. The latter result extends to any logic in which the existence of sinks may be stated.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Computation of Optimal Current References for Flux-weakening of Multi-Phase Synchronous Machines [PDF]

open access: yes, 2012
Multi-phase synchronous machines are more and more used in specific applications where high power density, low bus voltage, wide speed range and fault-tolerant capabilities are required. Due to the high number of degrees of freedom, multi-phase machines
