Semantic Modeling in Materials Science and Engineering With Platform MaterialDigital Core Ontology 3.0

open access: yesAdvanced Engineering Materials, EarlyView.
The community‐driven Platform MaterialDigital Core Ontology (PMDco) 3.0 is introduced as a Basic Formal Ontology‐aligned semantic backbone for the processing–structure–properties paradigm in Materials Science and Engineering. Modular engineering, automated releases, and validation workflows are highlighted and key semantic patterns for materials ...

Finite element assisted method of estimating equivalent circuit parameters for a superconducting synchronous generator with a coreless rotor

open access: yes, 2008
The paper outlines methods developed to obtain circuit parameters of a superconducting synchronous generator with a coreless rotor. The need for full 3D finite element modelling is emphasised and appropriate techniques devised to estimate relevant ...

Position-sensorless control of permanent-magnet-assisted synchronous reluctance motor [PDF]

open access: yes, 2003
The sensorless control of permanent-magnet-assisted synchronous reluctance (PMASR) motors is investigated, in order to conjugate the advantages of the sensorless control with full exploitation of the allowed operating area, for a given inverter.

Reverse-Link Performance of Synchronous DS-CDMA Systems in Dispersive Rician Multipath Fading Channels

open access: yes, 2003
The reverse-link performance of synchronous DS-CDMA is investigated in Rician multipath fading environments. The numerical results show that the performance benefits of synchronous transmission depend on the specular path’s power as well as on the ...

Triple Synchronous Colorectal Cancer: An Extremely Rare Case Underscoring the Need for Careful Perioperative Evaluation

open access: yesGastrointestinal Disorders
Synchronous colorectal cancer (SCRC) is characterized by the simultaneous occurrence of two or more primary colorectal malignancies, diagnosed either preoperatively, intraoperatively, or within six months postoperatively.

Synchronous Ipsilateral Pleomorphic Adenomas of Parotid and Submandibular Glands: An Unusual Finding

open access: yesCase Reports in Otolaryngology, 2020
A rare case of synchronous ipsilateral pleomorphic adenomas (PA) of the left parotid and submandibular glands is reported. Simultaneous multiple PA in major salivary glands are a very rare entity, and merely few cases of ipsilateral synchronous PA ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Battle flags hanging in Ohio History Center plaza

open access: yes, 1970
Photograph of Ohio's Battle Flag collection hanging in the plaza of the Ohio History Center in Columbus, Ohio, ca. 1970. The flags were displayed on the Center’s plaza level from the time the building opened in 1970 through the late 1980s, when they were

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Alternative designs of high-temperature superconducting synchronous generators

open access: yes, 2010
This paper discusses the different possible designs of both cored and coreless superconducting synchronous generators using high-temperature superconducting (HTS) tapes, with particular reference to demonstrators built at the University of Southampton ...
