Period Spaces for Hodge Structures in Equal Characteristic [PDF]

open access: yes, 2011
We develop the analog in equal positive characteristic of Fontaine's theory for crystalline Galois representations of a p-adic field. In particular we describe the analog of Fontaine's functor which assigns to a crystalline Galois representation an ...

Review on reliability assessment of energy storage systems

open access: yesIET Smart Grid, Volume 7, Issue 6, Page 695-715, December 2024.
As renewable energy, characterised by its intermittent nature, increasingly penetrates the conventional power grid, the role of energy storage system (ESS) in maintaining energy balance becomes paramount. The authors examine a variety of ESS technologies, highlighting their critical function in ensuring a stable and reliable energy supply.

Reliability–flexibility integrated optimal sizing of second‐life battery energy storage systems in distribution networks

open access: yesIET Renewable Power Generation, Volume 18, Issue 13, Page 2177-2193, 5 October 2024.
A reliability‐flexibility integrated optimal sizing method for second‐life batteries (SLBs), comprising an upper level that determines the sizing of SLBs and a lower level that ensures optimal operation of the distribution network, is proposed. Abstract Second‐life batteries (SLBs), which are batteries retired from electric vehicles (EVs), can be used ...

Dynamic Fuzzy Reliability Analysis of Multistate Systems Based on Universal Generating Function

open access: yesMathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
Considering the fuzziness of load, strength, operational states, and state probability, reliability models of multistate systems are developed based on universal generating function (UGF). The fuzzy UGF of load and the fuzzy UGF of strength are proposed in this paper, which are used to derive the fuzzy component UGF and the fuzzy system UGF.

Profiloplasty and facial contouring with injectables: A holistic, practical, and user‐friendly approach

open access: yesJournal of Cosmetic Dermatology, Volume 23, Issue 10, Page 3158-3172, October 2024.
Abstract Background Expansion of the aesthetic treatment armamentarium with novel injectable products has greatly improved our ability to reshape and enhance the facial profile. However, full‐face “profiloplasty” with injectables remain a nascent concept and is insufficiently considered in daily practice. While techniques have been widely published for

Dynamic Importance Analysis of Components with Known Failure Contribution of Complex Systems

open access: yesMathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
Importance analysis deals with the investigation of influence of individual system component on system operation. This paper mainly focuses on dynamic important analysis of components in a multistate system. Assuming that failure probabilities of system components are independent, a new time integral‐based importance measure approach (TIIM) is proposed
