Continuous bunch-by-bunch spectroscopic investigation of the microbunching instability [PDF]

Physical Review Accelerators and Beams, 2018
Electron accelerators and synchrotrons can be operated to provide short emission pulses due to longitudinally compressed or sub-structured electron bunches. Above a threshold current, the high charge density leads to the micro-bunching instability and the formation of sub-structures on the bunch shape.

Bounds and Bunching: Distributions of Air Pollutants Produced by New Automobiles

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015
Euro norms set limits on per-kilometer emissions of air pollutants produced by new cars. Satisfying these limits is always costly, the existing models generally assume that cars are produced as to just satisfy the norms.

Identifying Spatial–Temporal Characteristics and Significant Factors of Bus Bunching Based on an eGA and DT Model

Applied Sciences, 2022
Bus bunching is a common phenomenon caused by irregular bus headway, which increases the passenger waiting time, makes the passenger capacity uneven, and severely reduces the reliability of bus service.

Excitation and suppression of asymmetric modes in a coaxial relativistic klystron amplifier with cascaded single-gap bunching cavities

AIP Advances, 2022
The excitation and suppression of asymmetric modes in a coaxial relativistic klystron amplifier (RKA) with cascaded single-gap bunching cavities are analyzed in this paper.

SAR Image Generation of Ocean Surface Using Time-Divided Velocity Bunching Model [PDF]

Journal of the Korean Institute of Electromagnetic Engineering and Science, 2019
An efficient synthetic aperture radar (SAR) image formulation based on the velocity-bunching model is proposed for a large SAR image integration time. A time-varying ocean surface is generated based on the semi-empirical spectrum proposed by Fung and Lee.

Modeling bus bunching and anti-bunching control accounting for signal control and passenger swapping behavior

, 2021
The conventional bus propagation process has two main shortcomings: one is bus bunching, the other is extra energy consumption by idling at signalized intersection and unexpected speed variation along the route. To overcome these problems simultaneously,

Tax Bunching, Income Shifting and Self-employment [PDF]

, 2012
This paper proposes a dynamic extension to Saez (2010) bunching formula that allows us to distinguish bunching based on real responses and income shifting.

Bunching: una revisión

El Trimestre Económico, 2023
La progresividad del sistema fiscal descansa en el impuesto sobre la renta de las personas físicas en la mayoría de los países avanzados. Sin embargo, esta estructura genera cambios en el comportamiento de los contribuyentes.
