德国的道路上，每两分钟就会发生一起由于野生动物引发的交通事故。仅2015年，就给德国的保险行业造成了超过6亿欧元的损失。为了解决这一难题，乌尔姆应用科技大学、海尔布隆应用科学大学以及工业合作伙伴共同创建了“SALUS”。通过雷达、光学相机、红外传感器和神经网络的组合，打造出了一个能够区分行人、汽车、自行车骑行者、摩托车骑行者、鹿、狐狸和野猪等物体的机器学习系统。该系统能够向汽车司机和其它道路使用者...
Dynamic Routing and Spectrum Assignment in Flexible Optical Path Networks
Dynamic Routing Flexible Optical Path Network Spectrum Assignment
2015/5/15
We propose dynamic routing and spectrum assignment algorithms for bitrate-flexible lightpaths in OFDM-based optical networks. The novel algorithms enable dynamic spectrum assignment with more efficien...
Spectral Reflectance Characteristics of Different Snow and Snow-Covered Land Surface Objects and Mixed Spectrum Fitting
Snow Snow-covered land surface object Spectral characteristics Spectral fitting
2012/4/17
The field spectroradiometer was used to measure spectra of different snow and snow-covered land surface objects in Beijing area. The result showed that for a pure snow spectrum, the snow reflectance p...
Gain spectrum of an optical parametric amplifier with a temporally-incoherent pump
Gain spectrum optical parametric amplifier temporally-incoherent pump
2015/6/10
We report on the performance of a fiber optical parametric amplifier pumped with a temporally-incoherent pump. Parametric gain coefficients seven times higher than that of a coherently pumped amplifie...
On the Spectrum-Efficiency of Bandwidth-Variable Optical OFDM Transport Networks
Spectrum-Efficiency Bandwidth-Variable Optical OFDM Transport Networks
2015/6/10
We investigated the high spectrum efficiency property of the bandwidth-variable optical OFDM (BV-OOFDM) transport networks. In contrast to mixed-line-rate (MLR) networks, BV-OOFDM enables flexible all...
Characterization of a Mode-Locked Quantum-Dash Fabry-Perot Laser Based on Measurement of the Complex Optical Spectrum
Mode-Locked Quantum-Dash Fabry-Perot Laser Complex Optical Spectrum
2015/7/17
By measuring the complex optical spectrum using a half-rate, sinusoidal modulation method, a mode locked quantum-dash Fabry-Perot laser is characterized for free-running operation and actively mode-lo...
1 Tb/s Optical Path Aggregation with Spectrum-Sliced Elastic Optical Path Network SLICE
Optical Path Aggregation Spectrum-Sliced Elastic Optical Path Network SLICE
2015/7/16
We demonstrate highly spectrally-efficient path aggregation directly in the optical domain. Multiple hundred-gigabit class flows are aggregated into a seamless 1 Tb/s optical path and transmitted in s...
