Comparative analysis and improved design of LLC inverters for induction heating

open access: yesIET Power Electronics, 2023
This work presents a comparative analysis and design procedure of a converter based on an LLC resonant inverter used for induction heating applications depending on the transistor technology used and the selected operating frequency. A major objective of

Fundamental aspects of processing multi-metallic components using additive manufacturing technologies

open access: yesEuropean Journal of Materials, 2022
Additive Manufacturing (AM) has triggered development of advanced materials and supply chain strategies. Almost all newly launched metallurgical processing routes had initial technical limitations arising from the fact that their process-property ...

The Missing Piece in the CASEL Model: The Impact of Social–Emotional Learning on Online Literature Teaching and Learning

open access: yesEducation Sciences, 2023
The use of social–emotional learning (SEL) practices in online literature teaching has not yet been sufficiently researched. This study addresses this lacuna by identifying SEL practices mentioned by lecturers and preservice teachers (PSTs) as they ...

Gut Microbiota Dysbiosis in BK Polyomavirus-Infected Renal Transplant Recipients: A Case-Control Study

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
BackgroundBK polyomavirus infection results in renal allograft dysfunction, and it is important to find methods of prediction and treatment. As a regulator of host immunity, changes in the gut microbiota are associated with a variety of infections ...

Inductive-Inductive Definitions [PDF]

open access: yes, 2010
We present a principle for introducing new types in type theory which generalises strictly positive indexed inductive data types. In this new principle a set A is defined inductively simultaneously with an A-indexed set B, which is also defined inductively.

Quotient Inductive-Inductive Types [PDF]

open access: yes, 2018
Higher inductive types (HITs) in Homotopy Type Theory (HoTT) allow the definition of datatypes which have constructors for equalities over the defined type. HITs generalise quotient types and allow to define types which are not sets in the sense of HoTT (i.e.

Signatures and Induction Principles for Higher Inductive-Inductive Types

open access: yesLogical Methods in Computer Science, 2020
Higher inductive-inductive types (HIITs) generalize inductive types of dependent type theories in two ways. On the one hand they allow the simultaneous definition of multiple sorts that can be indexed over each other. On the other hand they support equality constructors, thus generalizing higher inductive types of homotopy type theory.

Enhanced asymmetrical modulation for half‐bridge series resonant inverters in induction heating applications

open access: yesIET Power Electronics, 2023
This paper presents a method that improves the reliability of half‐bridge (HB) series resonant inverters (SRI) for high‐frequency induction heating applications. Many industrial processes, like induction heat treatments, are very repetitive.
