Bacteria attenuation modeling and source identification in Kranji Catchment and Reservoir
… run-off near the reservoir was the bacterial source of greatest concern. The relatively high concentrations coupled with short travel time, which diminishes opportunity for attenuation, resulted in high concentrations reaching the reservoir. Residential areas were found to contribute high …

Machine Learning Driven Source Identification, State Estimation and Sensor Optimization in Water Systems
… driven frameworks to tackle three problems: i) Source Identification (SI) of contaminants in sewer systems, ii) State Estimation (SE) of water quality parameters in water distribution systems, and iii) Sensor Placement Optimization (SPO) in both systems. Traditional methods proposed to address …

Rumor source identification, contagion processes, and dynamics of social network formation and evolution
… such flows. We examine the problem of rumor source identification in line graphs. As the size of the infected region grows arbitrarily large, we show that unlike the single source case, where the likelihood function concentrates near the midpoint of the infected region, the support of the …

Source identification of trichloroacetic acid with preparative capillary gas chromatography and accelerator mass spectrometry
A method for radiocarbon source identification of environmental chemicals present in soil at ppb levels using trichloroacetic acid (TCA) as an exemplary compound was developed in the present thesis. A powerful approach to differentiate between biogenic and anthropogenic sources of environmental …

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 …

Development of a Novel Methodology for the Identification of VOC Emission Sources in Indoor Environments based on the Material Emission Signatures and Air Samples measured by PTR-MS
… the research field of indoor air quality is the identification of indoor Volatile Organic Compound (VOC) emission sources to clearly pinpoint the sources of concern in a field condition. This study represents the first attempt in developing a new technique to find the sources that may be …

Enabling malware remediation in expanding home networks
… of the IP traceback problem as the residential source identification problem. As the IoT grows, the problem worsens: IoT devices are less capable of self-remediation and expected to soon outnumber traditional devices, thus imposing a significant cost on customers to triangulate and remediate an …

The Effects of Memory Retrieval Conflict on the Construction of a Deception
… cortical activation patterns were stronger for source identification and working memory than they were for the act of deception.</p>

Instrumentation in the Works of Witold Lutoslawski
… Chain 3 (1986), with an emphasis on the identification of instrumentational idiosyncrasies and the relationship of timbre, texture, and structural concerns. A biographical synopsis is included as well as a brief discussion of the background of the use of chance procedures and the …

Simulations for the International X-ray Observatory
… theory and observation. A distribution of point sources and various instrumental effects are also included. The simulator is complemented by a source identification method. The IXO selection function is mapped over a varying surface brightness parameter space. Simulated IXO surveys are used to …

Automated isotope identification and quantification using artificial neural networks
Current radioisotope identification devices struggle to identify and quantify isotopes in low-resolution gamma-ray spectra in a wide range of realistic conditions. Trained gamma-ray spectroscopists typically rely on intuition when identifying isotopes in spectra. A trained gamma-ray spectroscopist …

Acoustic Characterization and Preliminary Noise Control of Pneumatic Percussion Tools
… for the acoustic characterization and noise source identification of these percussion tools. The methodology is applied to a representative pneumatic tool and the characterization results are described in detail. A mechanical analysis was performed on a chipping hammer finding mode shapes and …

LORE Approach for Phased Array Measurements and Noise Control of Landing Gears
… creating a fairing around the major noise sources. The purpose of these devices is to reduce wake interactions and to hide components from the flow, thus, reducing the noise emission. The design of these fairings was focused on the major noise sources identified in a 777 main landing gear. …

Application of Multivariate Statistical Methodology to Model Factors Influencing Fate and Transport of Fecal Pollution in Surface Waters
… of fecal pollution is necessary to identify sources and effectively design and implement Best Management Practices (BMPs) to protect and restore surface water quality. Sinking Creek is listed on the State of Tennessee’s 303D list as impaired due to pathogen contamination. The need to address …

Optimisation of galaxy identification methods on large interferometric surveys
… fully automated three-dimensional (3D) source finding and parametrization tools. A fraction of the percentage difference in the performance of these automated tools corresponds to a significant number of galaxies being detected or undetected. Failure or success to resolve satellites …
