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

open access: yesApplied 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

open access: yesAIP 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]

open access: yesJournal 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.

Is the Nectar Sugar Content the Key to Improving Onion and Bunching Onion Seed Yield?

open access: yesHorticulturae, 2023
Bunching onion as well as onion show great variability in seed yield among cultivars. Understanding the role of floral rewards and attractants to pollinator species is crucial to improving crop seed yield.

Bunching and antibunching in four wave mixing NV center in diamond

open access: yesAIP Advances, 2018
The determination of classical and quantum states through photon bunching and anti-bunching like phenomena may have potential applications in quantum information processing and long-distance quantum communications. We report the photon bunching and multi

Klystron bunching with sustained electron acceleration in agriculture [PDF]

open access: yesE3S Web of Conferences, 2020
This article discusses klystron bunching with post-acceleration, when bunchers are placed in front of the accelerating tube, and the electronic seals previously formed during the acceleration are ungrouped.

The Effects of Repulsive and Attractive Interactions on Step Bunching Formed on Stepped Surfaces

open access: yesCumhuriyet Science Journal, 2018
A surface which consists concentric circular monoatomic steps in twodimensions and below its roughening temperature is discussed. Repulsive andattractive interactions between steps on the surface are considered.

Regulatory Employment Thresholds and Firm Size Distortions: Evidence from Ecuador

open access: yesEconomies
This study examines whether size-contingent employment regulations are associated with distortions in firm size distribution and whether such patterns are more consistent with productivity-based selection or with broader constraints on firm scaling ...

Risk factors affecting dairy cattle protective grouping behavior, commonly known as bunching, against Stomoxys calcitrans (L.) on California dairies.

open access: yesPLoS ONE, 2019
Bunching is the term used to describe the protective aggregating behavior of cattle against the painful bites of stable flies (Stomoxys calcitrans), where cattle gather in a group with their heads to the center of the group and their tails to the outside
