A road toward zero-spacing photonic waveguides and circuits
Europhysics Letters, 2023 Like their electronic counterparts, photonic integrated circuits face the challenge of further integration and miniaturization. One of the fundamental limitations comes from waveguide spacing, which leads to serious crosstalk between the neighboring ...

Considering Overhead Costs in Road and Landing Spacing Models
Journal of Forest Engineering, 1992 Existing road and landing spacing models assume that spacing affects only the costs of road construction and skidding. However, costs that are independent of production and fixed on the basis of time will vary with spacing when specified on a "per-unit ...

The road to the Deep Space Network
IEEE Spectrum, 1993The evolution of the National Aeronautical and Space Administration's (NASA's) Deep Space Network is recounted. The launching of the US Pioneer program, following the orbiting of Sputnik by the USSR in 1957, and the communication system established for it are examined.

Road surface distress detection in disparity space
2017 International Conference on Image and Vision Computing New Zealand (IVCNZ), 2017Automatic identification of potholes on roads is needed to avoid traffic accidents or to ensure better driving comfort. This paper presents a strategy which focuses on the detection of major distress present on a road surface using stereo vision. The proposed strategy performs road-plane modelling directly in the image-disparity space, without back ...

Safe spacing of unsignalized intersections on arterial roads
2009 IEEE/INFORMS International Conference on Service Operations, Logistics and Informatics, 2009It is well known that limited safety distance and excessive intersections are the main reasons of the increasing traffic accidents on arterial roads. Based on the highway functional classification and intersection control types, the intersection spacing mode is divided firstly to make sure the arterial road access spacing and intersection corner ...

Brazil: Origins - the road to space
2010In 1957, the International Geophysical Year, two students from the Technical Institute of Aeronautics (ITA) in Sao Jose dos Campos, in the Brazilian province of Sao Paulo, wrote a letter to the US Naval Research Laboratory. Fernando de Mendonca and Julio Alberto de Morais Coutinho wanted to install a device to monitor the signals from the Vanguard ...

A Review Of Road‐Gully Spacing Methods
Water and Environment Journal, 1996ABSTRACT Methods of spacing gullies on surface‐water drainage schemes have changed significantly during the last thirty years as the understanding of the hydrology and hydraulics of the subject has advanced. Rules of thumb which take no account of road geometry or inlet efficiency have been replaced by more rigorous methods, the most advanced of which ...
