Pointer Meter Reading Recognition by Joint Detection and Segmentation

open access: yesApplied Sciences
To handle the task of pointer meter reading recognition, in this paper, we propose a deep network model that can accurately detect the pointer meter dial and segment the pointer as well as the reference points from the located meter dial.

AUTONOMOUS DIAL-A-RIDE TRANSIT INTRODUCTORY OVERVIEW

open access: yes, 1995
This paper introduces a modernized version of many-to-few dial-a-ride called autonomous dial-a-ride transit (ADART), which employs fully-automated order-entry and routing-and-scheduling systems that reside exclusively on board the vehicle.

Comparison of CO2 Vertical Profiles in the Lower Troposphere between 1.6 µm Differential Absorption Lidar and Aircraft Measurements Over Tsukuba

open access: yesSensors, 2018
A 1.6 μm differential absorption Lidar (DIAL) system for measurement of vertical CO2 mixing ratio profiles has been developed. A comparison of CO2 vertical profiles measured by the DIAL system and an aircraft in situ sensor in January 2014 over the ...

First airborne water vapor lidar measurements in the tropical upper troposphere and mid-latitudes lower stratosphere: accuracy evaluation and intercomparisons with other instruments [PDF]

open access: yesAtmospheric Chemistry and Physics, 2008
In the tropics, deep convection is the major source of uncertainty in water vapor transport to the upper troposphere and into the stratosphere. Although accurate measurements in this region would be of first order importance to better understand the ...

Improvement of CO2-DIAL Signal-to-Noise Ratio Using Lifting Wavelet Transform

open access: yesSensors, 2018
Atmospheric CO2 plays an important role in controlling climate change and its effect on the carbon cycle. However, detailed information on the dynamics of CO2 vertical mixing remains lacking, which hinders the accurate understanding of certain key ...
