The direct space-to-time (DST) pulse shaping apparatus is investigated both theoretically and experimentally. The discussion shows how the operation of the DST pulse shaper may be understood in terms of the femtosecond response of a generalized spectrometer. A complete discussion of the advantages and tradeoffs of utilizing this pulse-shaping configuration is given, including the direct scaling...

In this article, enhancement of THz radiation was studied using pulse shaping thchnique. Over 40% enhance was demonstrated by positive chirped optical pulses. This could be attributed to the pump-dump process in excitation.

In this chapter we offer a framework for thinking about the design of technology. Our approach draws on critical perspectives from both social theory and science and technology studies (STS). We understand design to be the process of consciously shaping an artifact to adapt it to specific goals and environments. Our framework conceptualizes design as a process whereby technical and social consi...

Imitation Learning (IL) is a popular approach for teaching behavior policies to agents by demonstrating the desired target policy. While the approach has lead to many successes, IL often requires a large set of demonstrations to achieve robust learning, which can be expensive for the teacher. In this paper, we consider a novel approach to improve the learning efficiency of IL by providing a sha...

This study explores the extent to which subjective norm beliefs of online learners shape perceptions of ease-of-use and usefulness for the use of course delivery systems. Subjective norm beliefs represent the influence that instructors, mentors, and peers have on students to use the course delivery system. The results show that instructor and mentor influences are significant contributors to st...
