First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

An Exploration of Canoeing Action as Therapy for Spinally Injured People

open access: yesAdvances in Electrical and Electronic Engineering, 2004
This paper outlines the design and building of a kayak machine, for use by person with spinal injury. We designed an eddy current brake to apply varying known torques on the system, which determine the power required by the user to run the machine.

Power spectral density and the brain

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Time series from M/EEG (magneto/electroencephalography) and ECoG (electrocorticography) recordings are common sources of information about brain function. The power spectral density (PSD) preserves much of this information, up to second order. In the current decade, a burst of brain diagnostics using the slope of log(PSD) has appeared.

Brake Anti-slide Detection and Protection for Metro Vehicles

open access: yes机车电传动, 2015
Based on the weakness analysis of the traditional wheel-slip detect methods such as speed difference and decelerationcriterion, proposals were given for the reference speed calculation and over sensitive caused by deceleration-criterion. At the same time,

Directional and gradient patterning from sub‐microliter colloidal droplet evaporation on inclined and stretched soft substrates

open access: yesDroplet, EarlyView.
Instead of suppressing the ubiquitous “coffee‐ring” effect, we harness it by integrating stretching, inclination, and rotation of soft substrates. This sequential control allows manipulation of global pattern symmetry and local morphology. By incorporating substrate inclination and rotation of stretched soft substrates, we create diverse patterns that ...

Research on Current Source Inverter Application in AC-DC Locomotive Braking Mode

open access: yes机车电传动, 2016
AC-DC electric locomotive generally used feedback-resistor braking mode, which took energy from traction power network to ensure the cooling fan working, resulting in great resources waste and environmental pollution.

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Study of Brake Shoes Parameters on Brake Squeal Propensity Based on Complex Eigenvalue Method

open access: yes机车电传动, 2015
A finite element model of a pad-wheel brake device was established using ABAQUS to predict the brake squeal noise. The influence of friction coefficient between the friction body and the tread, Young’s modulus of the friction body and the back plate on ...

Daily Ovarian Hormone Exposure and Loss of Control Eating in Adolescent Girls: A Stage 2 Registered Report

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective This Stage 2 Registered Report examined (1) the main effects and interaction of within‐person daily associations between ovarian hormones (i.e., estrogen, progesterone) and loss of control eating (LOCE), and (2) the within‐person mediating roles of food‐related reward anticipation and response inhibition. Methods Adolescent girls (n =
