This paper examines four methods by which ground motions can be selected for dynamic seismic response analyses of engineered systems when the underlying seismic hazard is quantified via ground motion simulation rather than empirical ground motion prediction equations. Even with simulation-based seismic hazard, a ground motion selection process is still required in order to extract a small numbe...

In this work Laser wireless video communication system using intensity modualtion direct detection IM/DD over a 1 km range between transmitter and receiver is experimentally investigated and demonstrated. Beam expander and beam collimeter were implemented to collimete laser beam at the transmitter and focus this beam at the receiver respectively. The results show that IM/DD communication sysate...

services companies attempt to promote their delivered services to customers and achieve a stable competitive advantage. for achieving this goal, marketing and hr scholars jointly propose application of internal marketing (im) principles and instruments. although im is a 30 years old concept in management, but it's measurement and application method have faced with different structural and ...

A simple equilibrium restriction identifies time-varying components of expected returns. Using data from the Fama and French threeand fivefactor models and momentum, we use this restriction to predict factor returns out of sample. We derive a policy for timing exposures to these components and find the modified portfolio generates returns with higher out-of-sample Sharpe ratios than the underly...

Maximum likelihood sequence estimation (MLSE) has been proposed in earlier literature to combat the effects of nonlinear dispersion in intensity modulation/direct detection (IM/DD) optical channels. In this paper, we develop a theory of the bit error rate (BER) of MLSE-based IM/DD receivers operating in the presence of nonlinear dispersion and amplified spontaneous emission (ASE) noise. We focu...

We report a high performance phase modulation direct detection microwave photonic link employing a photonic chip as a frequency discriminator. The photonic chip consists of five optical ring resonators (ORRs) which are fully programmable using thermo-optical tuning. In this discriminator a drop-port response of an ORR is cascaded with a through response of another ORR to yield a linear phase mo...
