We present an electro-absorption modulated laser with 6dBm modulated power leading to record power budget NRZ transmissions at 1.55μm: 37dB at 10Gb/s over 50km and 30dB at 28Gb/s over 10km with a pre-amplified photodiode.
A variety of motion planning algorithms has been developed over the past decades. For robotics, the transformation of the problem from the robot Cartesian space (workspace) to the configuration space (C-space) has been crucial — converting the problem of collision-checking between 3D objects to simpler, point-like, tests in the high-dimensional C-space. However, the C-space map-making is both computationally...
Integration of wind power generation into the grid makes important impacts on power system planning and operation due to variable nature of the wind power. This paper proposes a probabilistic approach to assess the security of a power system with high wind penetration within operational context. The principal advantage of the proposed probabilistic security assessment approach is that, when compared...
The failure rate in one of Hydro-Quebec's power plants is about three times higher than in the rest of the fleet. Over the years a total of 10 failures occurred for the six units of this plant. Spare bars were put in after every failure and the units returned to service. Apart from a few incidents, the failures were almost exclusively on bottom bars. Failed bars were retrieved and cross-section slices...
In 2002, we reported a CCD image sensor with 260x312 pixels capable of capturing 103 consecutive images at 1,000,000 frames per second (1Mfps). We named the sensor "ISIS-V2", for In-situ Storage Image Sensor Version 2.103 memory elements are attached to every pixel; generated image signals were instantly and continuously stored in the in-situ storage without being read out of the sensor...
This paper discusses the behavior of wind energy systems in grid fault events and existing strategies for these systems to ride through the faults. Various issues of wind power conversion systems with different generators in case of grid faults are described. Finally, existing enhancement methods of fault ride through capabilities to meet the main grid codes for each type of wind turbines are shown...
