In-use, fuel-based motor vehicle emission factors were determined using measurements made in a highway tunnel in Pittsburgh, Pennsylvania. Concentrations Of PM2.5 mass, CO, CO2, and NO, were measured continuously. Filter-based measurements included PM2.5 m ...
This thesis presents the coherence properties of polaritons in semiconductor microcavities. Semiconductor microcavities are microstructures in which the exciton ground state of a semiconductor quantum well is coupled to a photonic mode of a microresonator. ...
Air pollution is an important aspect for transportation, particularly car emission in urban area. The objective of this paper is to evaluate the global emission of a transport network based on probe car and traffic sensor data. This paper used the microsim ...
Air pollution is becoming a more and more important aspect for transportation, particularly car emission in urban area. The objective of this paper is to evaluate the global emission of a transport network based on probe car and sensor data. Probe vehicles ...
Light emission during the collision of ions and cluster ions on a metal surface covered by rare gas matrices of variable thickness is reported. The light intensity as a function of distance from the metal surface follows the classical image dipole theory. ...
We present in this paper an analysis of the electromagnetic emission associated with power line communications (PLC) systems. Using coupling factors obtained experimentally for different typical indoor configurations, we calculate radiated fields associate ...
We have performed a study of excitation power-dependent spectra of GaN/AlGaN single quantum wells (QWs). First, the experimental "blueshift" of the emission energy, due to screening of internal piezoelectric fields, was compared with the model calculations ...
The influence of hydrostatic pressure on the emission and absorption spectra measured for various types of InGaN structures (epilayers, quantum wells, and quantum dots) is studied. While the known pressure coefficients of the GaN and InN band gaps are abou ...
The ion-pair state emission spectra of I2 isolated in Ne, Ar, and Kr matrixes at 300-700 nm and vacuum UV spectra at 50,000-60,000 cm-1 are presented. Spectroscopic anal. of the UV and visible emission bands of the lowest-lying ion-pair state D'(2g) in Ne ...
Near-field optical spectroscopy is used to investigate the effects of disorder in the optical processes in semiconductor quantum wires. We observe photoluminescence emissions from extended, delocalized excitons at low temperatures (5 K) and low excitation ...
