A Time Difference Method for Measurement of Phase Shift between Distributed Feedback Laser Diode (DFB-LD) Output Wavelength and Intensity
A time difference method to conveniently measure the phase shift between output wavelength and intensity of distributed feedback laser diodes (DFB-LDs) was proposed. This approach takes advantage of asymmetric absorption positions at the same wavelength during wavelength increase and decrease tuning processes in the intensity-time curve by current modulation. For its practical implementation, a...
متن کاملDigital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
متن کاملRelationship between Shift Work and Job Satisfaction among Nurses: a Cross-sectional Study
Background and Objectives: Shift working has the potential to negatively influence the quality of work life among nurses. The purpose of this study was to investigate the outbreak of shift work-related disorders and the relationship between shift work and job satisfaction in nurses of Ilam University’s subsidiary hospitals, in order to identify potential strategies for decreasing risk of health...
متن کاملThe relationship between shift work and metabolic syndrome: a prospective cohort study
Background: Metabolic syndromes have been identified as a major risk factor for people with cardiovascular disease. Metabolic syndromes are defined as a range of conditions including waist-fat, abdominal obesity, high blood pressure, diabetes, high triglycerides, and HDL. Considering the importance of controlling metabolic syndrome, the research study subject with the mentioned aim is so import...
متن کاملAnalytical and Experimental Comparisons Between the Frequency-Modulated-Frequency-Shift Measurement and the Pulsed-Wave-Time-Shift Measurement Doppler Systems
In previous publications, a new echo-ranging Doppler system based on transmission of repetitive coherent frequency-modulated ͑FM͒ sinusoids in two different implementations was presented. One of these implementations, the frequency-modulated–frequency-shift measurement ͑FM–fsm͒ Doppler system is, in this paper, compared with its pulsed-wave counterpart, the pulsed-wave– time-shift measurement ͑PW–ts...
