Usage-Driven Unified Model for User Profile and Data Source Profile Extraction
… queries as support of analysis to extract a profile model. The objective is to characterize the user and the data source that interact in a system to allow different types of comparison (user-to-user, sourceto- source, user-to-source). According to the study we conducted on the work done on …

Particle Class Balance for Apportioning Aerosol Mass
… in a short analysis time. To exploit CCSEM as a source apportionment receptor modeling technique, it is important to define the membership of each particle in a well defined particle class. Various clustering methods were examined to obtain possible members of homogeneous particle classes. An …

Microwave Interferometric Measurements of Electron Density in Laser-Generated Plasma Channels
… resulted in a $\delta$-function excitation source, allowing the subsequent plasma decay to be explored without further excitation of the gas and without deconvolving the excitation source profile from the electron density decay data. The temporal resolution of the interferometer has been …

Design of organic Rankine cycles for conversion of waste heat in a polygeneration plant
… cycles for the conversion of low grade heat sources, where steam cycles are known to be less efficient and more expensive. This work examines organic Rankine cycles for use in a polygeneration plant that converts coal feedstock into hydrocarbon products and electricity. Since a Fischer …

Mass, Composition, Source Identification and Impact Assessment for Fine and Coarse Atmospheric Particles in the Desert Southwest
… laboratory, and analyzed to provide a chemical source profile for each soil type yielding insights into unique source signatures. Observations within the chemical speciation data and subsequent modeling analysis show a strong impact from local sources at the Cowtown site where mass …

Characterization, Speciation, and Source Apportionment of Particles inside and from the Exhaust of Public Transit Buses Fueled With Alternative Fuels
… compositions. Factor analysis suggested possible sources of indoor particle levels in public transit bus as motor vehicles, outdoor soil and secondary particle formation. The conclusion is that SEM methodology is a valuable tool for studying the distribution of particulates.</p><p>A part of this …

Rotation generation and transport in tokamak plasmas
… is transported via diffusive and convective profiles, and, using assumptions about the diffusive and convective terms, it can generate the profiles of the residual stress or source as a function of space and time. Several resultant source profile calculations are shown for SSEP sweeps, …

Applying Time-Valued Knowledge for Public Health Outbreak Response
… this opportunity be missed, substantially more resource-intensive, complex, and societally intrusive interventions may be required to achieve an acceptable outcome. These disparities place a differential on the value of a given unit of knowledge across the time-domains of an epidemic. Within this …

Generation, Characterisation and Potential Health Effects of Tyre Wear Particles
… has developed a comprehensive, multi-element source profile comprising over 70 tyres, the largest sample size of pristine tyre rubber representative of the UK market to date. This profile gives a snapshot of the elemental composition of tyres available on the UK market and has been provided …

Temporally Correlated Dirichlet Processes in Pollution Receptor Modeling
… pollution is understanding pollution sources. Various methods have been used and developed to understand pollution sources and the amount of pollution those sources emit. Multivariate receptor modeling seeks to estimate pollution source profiles and pollution emissions from …
