Very long transients in globally coupled maps [PDF]

open access: yes, 1999
Very long transients are found in the partially ordered phase of type II of globally coupled logistic maps. The transients always lead the system in this phase to a state with a few synchronous clusters.

Transient pseudohypoaldosteronism

open access: yesSrpski arhiv za celokupno lekarstvo, 2011
Introduction. Infants with urinary tract malformations (UTM) presenting with urinary tract infection (UTI) are prone to develop transient type 1 pseudohypoaldosteronism (THPA1). Objective. Report on patient series with characteristics of THPA1, UTM and/or UTI and suggestions for the diagnosis and therapy. Methods.

Understanding Epileptiform After-Discharges as Rhythmic Oscillatory Transients [PDF]

open access: yes, 2017
Electro-cortical activity in patients with epilepsy may show abnormal rhythmic transients in response to stimulation. Even when using the same stimulation parameters in the same patient, wide variability in the duration of transient response has been ...

A period distribution of X-ray binaries observed in the central region of M31 with Chandra and HST

open access: yes, 2012
Almost all Galactic black hole binaries with low mass donor stars are transient X-ray sources; we expect most of the X-ray transients observed in external galaxies to be black hole binaries also.

Transients in Input and Output Signals in DC–DC Converters Working in Maximum Power Point Tracking Systems

open access: yesEnergies, 2023
Designing a maximum power point tracking system (MPPT) can raise many questions when it comes to choosing the best converter and algorithm for the job. The number of possible solutions can be overwhelming, especially when it comes to MPPT algorithms. New

Further Improvements in Topological Transformer Model Covering Core Saturation

open access: yesIEEE Access, 2022
This paper is devoted to improvements of the low-frequency topological model of a three-legged stacked-core transformer. It is shown that $B-H$ hysteresis loops employed in the transformer model and $\Psi -i$ curves measured at transformer terminals ...

Simulation of surface deformation control during selective laser melting of AlSi10Mg powder using an external magnetic field

open access: yesAIP Advances, 2019
Selective laser melting (SLM) produces complex physical behaviors. After laser melting, the molten pool condenses with an uneven surface, which influences the next powder spreading process and affects the quality of the final product.

Impeller Optimized Design of the Centrifugal Pump: A Numerical and Experimental Investigation

open access: yesEnergies, 2018
Combined numerical simulation with experiment, blade wrap angle, and blade exit angle are varied to investigate the optimized design of the impeller of centrifugal pump. Blade wrap angles are 122°, 126°, and 130°. Blade exit angles are 24°

IMPROVING THE DYNAMIC CHARACTERISTICS OF ELECTRIC DISCHARGE INSTALLATIONS, WHICH ARE SIGNIFICANTLY DISTANT FROM THE SPARK-EROSION LOAD

open access: yesТехнічна електродинаміка, 2022
The paper identifies the features of the influence of the characteristics of different connecting conductors on the dynamic characteristics of electric discharge installations (EDIs), which are distant significantly (several meters) from the spark ...

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.
