FDTD analysis of direct optical integration between SiNx waveguides and Ge/SiGe multiple quantum wells on graded buffer for low-voltage optical modulators around the O-band wavelength

Results in Optics
We focus on investigating the possibility to achieve a direct butt coupling integration of SiNx passive waveguides with germanium/silicon–germanium (Ge/SiGe) multiple quantum wells (MQWs) on a thick graded buffer platform using 3D finite-difference time ...

Modelling the impact of traffic incidents on travel time reliability [PDF]

, 2016
Traffic incidents are recognised as one of the key sources of non-recurrent congestion that often leads to reduction in travel time reliability (TTR), a key metric of roadway performance.

Feel the Time. Time Perception as a Function of Interoceptive Processing

Frontiers in Human Neuroscience, 2018
The nature of time is rooted in our body. Constellations of impulses arising from the flesh constantly create our interoceptive perception and, in turn, the unfolding of these perceptions defines human awareness of time.

Examining the Impact of Adverse Weather on Travel Time Reliability of Urban Corridors in Shanghai

Journal of Advanced Transportation, 2020
Travel time reliability (TTR) is widely used to evaluate transportation system performance. Adverse weather condition is an important factor for affecting TTR, which can cause traffic congestions and crashes. Considering the traffic characteristics under

Evaluating the Environmental Impact: A Multisensor Remote Sensing Approach for Spatial and Temporal Analysis

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study quantifies the potential environmental impacts of the Karakoram highway (KKH) construction, which links the northern region of Pakistan with Western China. The upgrade of the KKH was carried out under the China-Pakistan Economic Corridor (CPEC)

Memory Organization for a Cubic Frame Buffer

, 1986
A special memory organization of a cubic voxel-based frame buffer is presented. The memory of voxels is divided into n modules of voxels each. The k-th module groups together all the principal diagonal planes within the cubic frame buffer, that their ...

GLMI: An Efficient Spatiotemporal Index Leveraging Geohash and Piecewise Linear Models for Optimized Query Performance

Algorithms
Spatiotemporal big data contain information in multiple dimensions such as space and time. Spatiotemporal data have the characteristics of large volume, intricate spatiotemporal relationship, and uneven spatiotemporal distribution. Index structure is one

Associations of the perceived and objective neighborhood environment with physical activity and sedentary time in New Zealand adolescents

International Journal of Behavioral Nutrition and Physical Activity, 2017
Background There is accumulating evidence supporting the association between neighborhood built environments and adults’ physical activity (PA) and sedentary time (ST); however, few studies have investigated these associations in adolescents.
