Two books offer complementary insights into how artificial intelligence is shaping society.

The participation of citizens in a democratic government is often influenced by the media, particularly new communication technologies. The differences between mass media and new media are pertinent to understanding how each works to shape our opinions and perceptions. Students need to understand the role of both traditional mass media outlets and new media in shaping public participation in ou...

Pulse shaping technology is present to mitigate pulse narrowing and SBS effects in high energy/power ns fiber lasers and to balance SPM and gain narrowing in high energy/power fs fiber lasers. © 2010 Optical Society of America OCIS codes: 140,3510; 140,3500; 140,4050.

This paper describes new efficient Vector Quantization (VQ) techniques that enable low complexity implementations of VQbased Noise Feedback Coding (NFC). These methods offer mathematical equivalence to higher complexity methods. Furthermore, the paper presents efficient codec structures for general noise shaping as used in BroadVoice®16 – a new SCTE® (Society of Cable Telecommunications Enginee...

We investigate optical transmission systems using optical arbitrary waveform generation and measurement supporting any modulation format and scalable to >Tb/s. Experiments include 1.2 Tb/s packet generation and 3 b/s/Hz spectral efficiency and dispersion pre-compensated transmission. ©2010 Optical Society of America OCIS codes: (320.5540) Pulse Shaping; (060.1660) Coherent Communications; (320....

We describe the precise shaping and mode-resolved amplitude and phase characterization of optical arbitrary waveforms by using a 20 GHz optical frequency comb and integrated 64 20 GHz channel arrayed waveguide grating pair. Complex waveforms with large variations in phase and amplitude between adjacent modes were generated and characterized. © 2007 Optical Society of America OCIS codes: 320.710...
