Multivariate Tests for Comparing Lifetimes of Parallel Systems

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Life testing of engineering systems with dependent components requires robust multivariate methods. Parametric approaches depend on restrictive assumptions, limiting their use in complex or unknown lifetime distribution settings. This study evaluates nonparametric methods for comparing parallel system lifetimes under minimal sample ...

Optimal Accelerated Life Testing Design Under Constrained Resources Using Double Deep Q‐Learning

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Accelerated life tests (ALTs) are essential tools for estimating product reliability under high‐stress conditions, allowing failure data to be collected in reduced timeframes. However, planning effective ALT configurations is a complex task that requires selecting stress levels, test durations, and unit allocations while accounting for limited

From Microstructure to Macroscopic Performance: A Comprehensive Study on Low‐K Oxide‐Doped BNT–LST–NN Ceramics for Energy Storage

Rare Metals, EarlyView.
ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Platform competition and strategic trade‐offs for complementors: Heterogeneous reactions to the entry of a new platform

Strategic Management Journal, EarlyView.
Abstract Research Summary We study how the entry of a rival platform affects the strategies of the incumbent's complementors. The latter face a trade‐off: While the entry threatens their benefits from indirect network effects, it also allows them to escape intense within‐platform competition.

Wind Energy Potential Assessment for Nooriabad Sindh Pakistan

International Journal of Economic and Environment Geology, 2020
Wind speeds recorded at regular intervals of time for a particular wind site correspond to intermittent source of energy. Reliable estimate of wind potential for the site requires fitting of the recorded data to a continuous distribution

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Study on Electrical Properties of Silicone Rubber Insulation for Cable Accessories Under Mechanical Stretching

High Voltage, EarlyView.
ABSTRACT Silicone rubber (SR) is extensively used as insulation for cable accessories, directly affecting their design and operation. The distinctive feature of cable accessory insulation, operating under mechanical stretching, has not received sufficient attention in relevant standards and research.

Thermal Conductive Network Construction and Enhanced Thermal Conductivity in Mica Tape Composites for Large Generators by Pre‐Placed h‐BN@PDA‐Modified Mica Paper

High Voltage, EarlyView.
ABSTRACT The lower thermal conductivity (TC) of mica tape hinders the evolution of large generators towards higher voltage and capacity. To enhance the TC of the mica tape, with the help of the three‐dimensional (3D) multi‐layer framework of the mica paper, a 3D polydopamine‐coated boron nitride (h‐BN@PDA) TC network was constructed by pre‐placing h‐BN@

Dielectric Response of Large Band Gap Cyclic Olefines With Symmetric and Asymmetric Pendant Polar Groups

High Voltage, EarlyView.
ABSTRACT The dielectric response of two typical polyoxafluoronorbornene with asymmetric and symmetric pendant polar groups is investigated to better understand the impact of the polymer structure on dielectric properties. Based on the Dissado–Hill modelling of broadband dielectric response, the contribution of the bicyclic backbone and fluorinated ...
