An Inductor-Less, Discontinuous Current Source Gate Driver for SiC Devices

open access: yesIEEE Access, 2019
EMI has remained a limiting factor in driving the SiC MOSFETs to its maximum potential and achieving a trade-off between EMI and switching losses is a major challenge for the designers.

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Fisher–Kolmogorov–Petrovskii–Piscounov Equation with Delay

open access: yesМоделирование и анализ информационных систем, 2015
We considered the problem of density wave propagation in a logistic equation with delay and diffusion (Fisher–Kolmogorov equation with delay). It was constructed a Ginzburg–Landau equation in order to study the qualitative behavior of the solution near ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Vedic algorithm for cubic computation and VLSI implementation

open access: yesEngineering Science and Technology, an International Journal, 2017
Algorithm of cubic computation and its VLSI implementation is described in this paper through ‘Vedic mathematics’ formulae. An N-bit cubic implementation circuit was structured into two cubic subgroups (bit length = N2 or lesser), multiplier and adder ...
