Experimental and simulation‐based investigations on throttle’s head loss coefficients of a surge tank

open access: yesEnergy Science & Engineering, 2020
For the different types of throttled surge tanks used in hydropower systems, it is important to comprehensively know the throttle's head loss characteristics for exact surge analysis and transient control.

Skew throttling

open access: yes, 2019
Zero forcing is a process that colors the vertices of a graph blue by starting with some vertices blue and applying a color change rule. Throttling minimizes the sum of the number of initial blue vertices and the time to color the graph. In this paper, we study throttling for skew zero forcing.

Human vs. Computer Slot Car Racing using an Event and Frame-Based DAVIS Vision Sensor [PDF]

open access: yes, 2015
This paper describes an open-source implementation of an event-based dynamic and active pixel vision sensor (DAVIS) for racing human vs. computer on a slot car track. The DAVIS is mounted in "eye-of-god" view.

Effect of cone throttle valve pressure on cavitation noise

open access: yesJurnal Engineering, 2020
The hydraulic cone throttle valve is prone to cavitation and cavitation noise. To address this problem, the authors studied the influence of cone throttle valve pressure and flow rate on cavitation noise.

A method for numerical simulation of mode transition process of compression system of variable cycle engine based on throttle valve model

open access: yesXibei Gongye Daxue Xuebao, 2022
In order to study the aerodynamic characteristics of the compression system of a variable-cycle engine during its mode transition, a low-order model was established based on the throttle valve theory to describe the throttle characteristics of the mode ...

Drive-style emission testing on the latest two Honda hybrid technologies [PDF]

open access: yes, 2009
Introduction Hybrid technology is seen by many as a potential solution to reduce vehicle emissions in cities. However type approval tests of hybrid vehicles measure emission levels comparable to those of conventional cars in the same market segment.

Integrated flight controller for light aircraft [PDF]

open access: yes, 1972
Controller-throttle engages spoiler/dive brake system when throttle setting is below a fixed power setting and gradually increases effect of spoiler/dive brake as throttle is moved toward idle position; since action is automatically reversible, a sudden ...
