Dynamic Bayesian Network for Continuous Health Index Estimation and Condition Assessment of Power Transformers

High Voltage, EarlyView.
ABSTRACT To address the limitations of traditional transformer health index (HI), such as high dependence on data integrity and inability to assist in diagnosing latent faults, this study proposes an HI prediction method based on dynamic Bayesian network (DBN).

Design flood estimation of cascade reservoirs based on vine-copula flood regional composition

Journal of Hydrology: Regional Studies
Study region: The study region is the Yalong River basin, the largest tributary of the Jinsha River in China. Study focus: The most likely flood regional composition (MLFRC) method has been widely used to estimate the design flood of cascade reservoirs ...

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions

Transactions of the Philological Society, EarlyView.
Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

Stochastic Frontier Models With Correlated Error Components [PDF]

In the productivity modelling literature, the disturbances U (representing technical inefficiency) and V (representing noise) of the composite error W=V-U of the stochastic frontier model are assumed to be independent random variables.

Neutral Forms of Be as Default Forms: The Utility of Underspecification and Blocking in a Welsh Morphosyntactic Phenomenon

Transactions of the Philological Society, EarlyView.
Abstract In Welsh, in certain tenses, unique forms of the verb for ‘be’ are used in positive clauses. These specialised forms of ‘be’ are incompatible with positive main‐clause declarative complementizers, despite their apparent featural compatibility. For most speakers, they are also blocked from if‐clauses; although, I report on data regarding their ...

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Effect of male age at the time of irradiation on the sexual performance of sterile Ceratitis capitata males: insights from remating female offspring

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an effective strategy for controlling insect pests, such as the Mediterranean fruit fly (Ceratitis capitata, Wiedemann). The effectiveness of the SIT depends on the ability of the sterile males to mate and their capacity to induce sterility in wild females.

Modeling Multivariate Distributions with Continuous Margins Using the copula R Package

Journal of Statistical Software, 2010
The copula-based modeling of multivariate distributions with continuous margins is presented as a succession of rank-based tests: a multivariate test of randomness followed by a test of mutual independence and a series of goodness-of-fit tests.

Self-Selection and Subjective Well-Being: Copula Models with an Application to Public and Private Sector Work [PDF]

We discuss a new approach to specifying and estimating ordered probit models with endogenous switching, or with binary endogenous regressor, based on copula functions. These models provide a framework of analysis for self-selection in economic well-being

Unravelling Evolutionary Dynamics of Female Sexual Cannibalism and Male Reproductive Strategies in Spiders

Integrative Zoology, EarlyView.
Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...
