Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The 4onse project studies non-conventional monitoring systems fully based on open technologies (hardware, standard protocols, software and data) for the management of resources and natural hazards in developing countries. After the design of hydro-meteorological stations and software for the collection, management and distribution of data, the study involves the installation of 30 stations in the Deduroya Oya river basin in Sri Lanka. The system will be analysed to fully understand the real cost of ownership, data quality and applicability in real situations. If properly validated, these systems can provide an alternative solution, effective and sustainable for the protection of property ...


Qgis Approach To Extract Fluvial Terraces For Archaeological Purposes Using Remote Sensing Data, Lia Duarte, Alberto Gomes, Ana Cláudia Teodoro, Sérgio Monteiro-Rodrigues Jul 2018

Qgis Approach To Extract Fluvial Terraces For Archaeological Purposes Using Remote Sensing Data, Lia Duarte, Alberto Gomes, Ana Cláudia Teodoro, Sérgio Monteiro-Rodrigues

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Fluvial terraces, normally defining flattened surfaces are significant geomorphic features that explains the presence of rivers at high altitudes and constitute the remains of the old river along the valley. In Iberia, many of these terraces preserve Paleolithic artifacts and document the presence of the first human communities. Nowadays, the increasing use of Free and Open Source Software (FOSS) provides the opportunity to analyze and test different approaches to study these geomorphological features. According to the literature, several algorithms from open source GIS software have been used, such as Geographic Resources Analysis Support System (GRASS) GIS. In the recent versions ...


Semantic Markup For Geographic Web Maps In Html, Malte Reißig Jan 2018

Semantic Markup For Geographic Web Maps In Html, Malte Reißig

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

In the recent years more and more geographical web maps have been developed and published on the Open Web Platform. Technically this has turned all variants of these maps into documents of the Hypertext Markup Language (HTML) making them appear to us naturally as graph-like and semi-structured data. In this dispute with geographical web maps and HTML we draw on the notion of so called “map mashups”. Requiring an alternative model and definition of what such a map is, our research allows us to build and refine supportive technology which helps us in analyzing and interpreting information map makers code ...

A Landscape Index Of Ecological Integrity To Inform Landscape Conservation, Kevin Mcgarigal, Brad Compton, Ethan Plunkett, Bill Deluca, Joanna Grand, Eduard Ene, Scott D. Jackson Jan 2018

A Landscape Index Of Ecological Integrity To Inform Landscape Conservation, Kevin Mcgarigal, Brad Compton, Ethan Plunkett, Bill Deluca, Joanna Grand, Eduard Ene, Scott D. Jackson

Environmental Conservation Faculty Publication Series

Context: Conservation planning is increasingly using "coarse filters" based on the idea of conserving "nature's stage". One such approach is based on ecosystems and the concept of ecological integrity, although myriad ways exist to measure ecological integrity.

Objectives: To describe our ecosystem-based index of ecological integrity (IEI) and its derivative index of ecological impact (ecoIpmact), and illustrate their applications for conservation assessment and planning in the northeastern United States.

Methods: We characterized the biophysical setting of the landscape at the 30 m cell resolution using a parsimonious suite of settings variables. Based on these settings variables and mapped ecosystems ...


Three-Dimensional Variations Of The Slab Geometry Correlate With Earthquake Distributions At The Cascadia Subduction System, Haiying Gao Jan 2018

Three-Dimensional Variations Of The Slab Geometry Correlate With Earthquake Distributions At The Cascadia Subduction System, Haiying Gao

Geosciences Department Faculty Publication Series

Significant along-strike variations of seismicity are observed at subduction zones, which are strongly influenced by physical properties of the plate interface and rheology of the crust and mantle lithosphere. However, the role of the oceanic side of the plate boundary on seismicity is poorly understood due to the lack of offshore instrumentations. Here tomographic results of the Cascadia subduction system, resolved with full-wave ambient noise simulation and inversion by integrating dense offshore and onshore seismic datasets, show significant variations of the oceanic lithosphere along strike and down dip from spreading centers to subduction. In central Cascadia, where seismicity is sparse ...


Persistent Radical Anion Polymers Based On Naphthalenediimide And A Vinylene Spacer, Sashi Debnath, Connor J. Boyle, Dongming Zhou, Bryan M. Wong, Kevin R. Kittilstved, Dhandapani Venkataraman Jan 2018

Persistent Radical Anion Polymers Based On Naphthalenediimide And A Vinylene Spacer, Sashi Debnath, Connor J. Boyle, Dongming Zhou, Bryan M. Wong, Kevin R. Kittilstved, Dhandapani Venkataraman

Chemistry Department Faculty Publication Series

Persistent n-doped conjugated polymers were achieved by doping the electron accepting PDNDIV and PFNDIVpolymers with ionic (TBACN) or neutral (TDAE) dopants. The great electron affinities, as indicated by the low LUMO levels of PDNDIV (−4.09 eV) and PFNDIV (−4.27 eV), facilitated the chemical reduction from either TBACN or TDAE. The low-lying LUMOs of the neutral polymers PDNDIV and PFNDIV were achieved by incorporation of vinylene spacers between the electron poor NDI units to increase the conjugation length without the use of an electron donor, and this was lowered further by an electron-withdrawing fluorinated N-substituent on the NDI ...


Modeling Non-Stationary Urban Growth: The Sprawl Model And The Ecological Impacts Of Development, Kevin Mcgarigal, Ethan Plunkett, Lisabeth L. Willey, Brad Compton, Bill Deluca, Joanna Grand Jan 2018

Modeling Non-Stationary Urban Growth: The Sprawl Model And The Ecological Impacts Of Development, Kevin Mcgarigal, Ethan Plunkett, Lisabeth L. Willey, Brad Compton, Bill Deluca, Joanna Grand

Environmental Conservation Faculty Publication Series

Urban development is a principal driver of landscape change affecting the integrity of ecological systems and the capacity of the landscape to support species. We developed an urban growth model (SPRAWL), evaluated it with hindcasting, and used it to simulate urban growth across the northeastern United States between 2010 and 2080 under four alternative scenarios. In the model, urban growth is constrained by demand for new development for each time step at the subregional scale. Demand is subsequently allocated to local application panes (5 km on a side within 15 km window) using a unique landscape context matching algorithm, such ...


Data For "Interplay Between Ion Transport, Applied Bias And Degradation Under Illumination In Hybrid Perovskite P-I-N Devices", Emily C. Smith, Christie L.C. Ellis, Hamza Javaid, Lawrence A. Renna, Yao Liu, Thomas P. Russell, Monojit Bag, Dhandapani Venkataraman Jan 2018

Data For "Interplay Between Ion Transport, Applied Bias And Degradation Under Illumination In Hybrid Perovskite P-I-N Devices", Emily C. Smith, Christie L.C. Ellis, Hamza Javaid, Lawrence A. Renna, Yao Liu, Thomas P. Russell, Monojit Bag, Dhandapani Venkataraman

Data and Datasets

We studied ion transport in hybrid organic inorganic perovskite p-i-n devices as a function of applied bias under device operating conditions. Using electrochemical impedance spectroscopy (EIS) and equivalent circuit modeling, we elucidated various resistive and capacitive elements in the device. We show that ion migration is predictably influenced by a low applied forward bias, characterized by an increased capacitance at the hole transporting (HTM) and electron transporting material (ETM) interfaces, as well as through the bulk. However, unlike observations in n-i-p devices, we found that there is a capacitive discharge leading to ion redistribution in the bulk at high forward ...


Polymeric Peptide Mimics For Protein Delivery, Coralie Backlund Jan 2018

Polymeric Peptide Mimics For Protein Delivery, Coralie Backlund

Doctoral Dissertations

The plasma membrane is a major obstacle in the development and use of biomacromolecules for intracellular applications. Consequently, proteins with intracellular targets represent an enormous, yet under studied avenue for therapeutics. Extended research has aimed at facilitating intracellular delivery of exogenous proteins using protein transduction domains (PTDs), which allow transport of bioactive molecules into cells. Synthetic polymers, inspired by PTDs, provide a well-controlled platform to vary molecular architecture for structure activity relationship studies. Specifically, this thesis focuses on the use of ring-opening metathesis, a facile and efficient polymerization technique, through which we can vary structural parameters to optimize delivery of ...


Gas-Surface Interactions: Reactive And Non-Reactive Scattering, Azar Farjamnia Jan 2018

Gas-Surface Interactions: Reactive And Non-Reactive Scattering, Azar Farjamnia

Doctoral Dissertations

The adsorption and dissociation of small molecules on metal surfaces are key steps in many industrial reactions. A detailed understanding of the dynamics of these reactions provides us with the ability to control the outcome and efficacy of the reactions. The molecule-metal interactions will lead to reorientation, energy redistribution, or bond dissociation in the molecule. The process is strongly depending upon the initial conditions, i. e. the incident energy and vibrational state of the molecule, and the surface temperature. We use a fully quantum approach to compute the dissociative sticking probability of the molecules at zero overage, on the surface ...


Synthesis Of Novel Zwitterionic Polymers: From Functional Surfactants To Therapeutics, Matthew Skinner Jan 2018

Synthesis Of Novel Zwitterionic Polymers: From Functional Surfactants To Therapeutics, Matthew Skinner

Doctoral Dissertations

This dissertation describes the synthesis, characterization, and investigation of novel zwitterionic polymers containing phosphorylcholine (PC), sulfobetaine (SB), and functional choline phosphate (CP) zwitterions for use as surfactants, self-assembled nanomaterials, and therapeutics. Facile, reproducible, and modular chemistries were utilized for incorporating zwitterions into a range of polymer backbones, and strategies were developed for overcoming difficult challenges encountered in zwitterionic polymer synthesis, especially related to the varying solubility of zwitterions, hydrophobic polymers, and functional comonomers. Synthetic strategies utilized in this work give access to well-defined materials with narrow molecular weight distributions, tunable compositions and architectures, and versatile chemical functionality.

Chapter 2 describes ...


Evolving Black Holes In Inflation, Ruth Gregory, David Kastor, Jennie Traschen Jan 2018

Evolving Black Holes In Inflation, Ruth Gregory, David Kastor, Jennie Traschen

Physics Department Faculty Publication Series

We present an analytic, perturbative solution to the Einstein equations with a scalar field that describes dynamical black holes in a slow-roll inflationary cosmology. We show that the metric evolves quasi-statically through a sequence of Schwarzschild–de Sitter like metrics with time dependent cosmological constant and mass parameters, such that the cosmological constant is instantaneously equal to the value of the scalar potential. The areas of the black hole and cosmological horizons each increase in time as the effective cosmological constant decreases, and the fractional area increase is proportional to the fractional change of the cosmological constant, times a geometrical ...


Invasive Species Risk Assessments Need More Consistent Spatial Abundance Data, Bethany A. Bradley, Jenica M. Allen, Mitchell W. O'Neill, Rebekah D. Wallace, Charles T. Bargeron, Julie A. Richburg, Kristina Stinson Jan 2018

Invasive Species Risk Assessments Need More Consistent Spatial Abundance Data, Bethany A. Bradley, Jenica M. Allen, Mitchell W. O'Neill, Rebekah D. Wallace, Charles T. Bargeron, Julie A. Richburg, Kristina Stinson

Environmental Conservation Faculty Publication Series

Spatial abundance information is a critical component of invasive plant risk assessment. While spatial occurrence data provide important information about potential establishment, abundance data are necessary to understand invasive species’ populations, which ultimately drive environmental and economic impacts. In recent years, the collective efforts of numerous management agencies and public participants have created unprecedented spatial archives of invasive plant occurrence, but consistent information about abundance remains rare. Here, we develop guidelines for the collection and reporting of abundance information that can add value to existing data collection efforts and inform spatial ecology research. In order to identify the most common ...


Responses Of Non-Native Earthworms To Experimental Eradication Of Garlic Mustard And Implications For Native Vegetation, Kristina A. Stinson, S. D. Frey, M. R. Jackson, E. Coates-Connor, M. Anthony, K. Martinez Jan 2018

Responses Of Non-Native Earthworms To Experimental Eradication Of Garlic Mustard And Implications For Native Vegetation, Kristina A. Stinson, S. D. Frey, M. R. Jackson, E. Coates-Connor, M. Anthony, K. Martinez

Environmental Conservation Faculty Publication Series

Recent studies in invasion biology suggest that positive feedback among two or more introduced organisms facilitate establishment within a new range and drive changes in native plant communities. Here, we experimentally tested for relationships between native plants and two non‐native organisms invading forest habitats in North America: garlic mustard (Alliaria petiolata, Brassicaceae) and earthworms. In two forested sites, we compared understory vegetation and earthworm biomass in plots where garlic mustard was removed for three years, plots without garlic mustard invasion, and plots invaded by garlic mustard that was not removed. Earthworm biomass was highest in the plots with garlic ...


Using Latent Variable Models To Improve Causal Estimation, Huseyin Oktay Jan 2018

Using Latent Variable Models To Improve Causal Estimation, Huseyin Oktay

Doctoral Dissertations

Estimating the causal effect of a treatment from data has been a key goal for a large number of studies in many domains. Traditionally, researchers use carefully designed randomized experiments for causal inference. However, such experiments can not only be costly in terms of time and money but also infeasible for some causal questions. To overcome these challenges, causal estimation methods from observational data have been developed by researchers from diverse disciplines and increasingly studies using such methods account for a large share in empirical work. Such growing interest has also brought together two arguably separate fields: machine learning and ...


Supporting Scientific Analytics Under Data Uncertainty And Query Uncertainty, Liping Peng Jan 2018

Supporting Scientific Analytics Under Data Uncertainty And Query Uncertainty, Liping Peng

Doctoral Dissertations

Data management is becoming increasingly important in many applications, in particular, in large scientific databases where (1) data can be naturally modeled by continuous random variables, and (2) queries can involve complex predicates and/or be difficult for users to express explicitly. My thesis work aims to provide efficient support to both the "data uncertainty" and the "query uncertainty".

When data is uncertain, an important class of queries requires query answers to be returned if their existence probabilities pass a threshold. I start with optimizing such threshold query processing for continuous uncertain data in the relational model by (i) expediting ...


Emergent Phenomena In Quantum Critical Systems, Kun Chen Jan 2018

Emergent Phenomena In Quantum Critical Systems, Kun Chen

Doctoral Dissertations

A quantum critical point (QCP) is a point in the phase diagram of quantum matter where a continuous phase transition takes place at zero temperature. Low-dimensional quantum critical systems are strongly correlated, therefore hosting nontrivial emergent phenomena. In this thesis, we first address two decades-old problems on quantum critical dynamics. We then reveal two novel emergent phenomena of quantum critical impurity problems. In the first part of the thesis, we address the linear response dynamics of the $(2+1)$-dimensional $O(2)$ quantum critical universality class, which can be realized in the ultracold bosonic system near the superfluid (SF) to ...


On The Performance Of Adaptive Bitrate Streaming And Parallel Cloud Applications, Cong Wang Jan 2018

On The Performance Of Adaptive Bitrate Streaming And Parallel Cloud Applications, Cong Wang

Doctoral Dissertations

As shown in recent studies, video streaming is by far the biggest category of backbone Internet traffic in the US. As a measure to reduce the cost of highly over-provisioned physical infrastructures while remaining the quality of video services, many streaming service providers started to use cloud services, where physical resources can be dynamically allocated based on current demand.

In this dissertation, we seek to evaluate and improve the performance for both Adaptive Bitrate (ABR) video streaming and cloud applications. First, we present a set of measurement studies for ABR streaming applications. Using the data from the application, network, and ...


Eccentricity Modulation Of Precessional Variation In The Earth’S Climate Response To Astronomical Forcing: A Solution To The 41-Kyr Mystery, Rajarshi Roychowdhury Jan 2018

Eccentricity Modulation Of Precessional Variation In The Earth’S Climate Response To Astronomical Forcing: A Solution To The 41-Kyr Mystery, Rajarshi Roychowdhury

Doctoral Dissertations

The 41,000-year variability of Earth’s glacial cycles during the late Pliocene-early Pleistocene is usually attributed to variations in Earth’s obliquity (axial tilt). However, a satisfactory explanation for the lack of precessional variation in marine d18O records, a proxy for ocean temperature and ice-volume, remains contested. Here, a physically based climate model is used to show that the climatic effect of precession is muted in global isotope records due to two different mechanisms, with each dominating as a function of eccentricity. At low eccentricities (e0.019), the time-integrated summer insolation and number of positive degree-days impacting ...


The Molecular Basis Of Caspase-9 Inactivation By Pka And C-Abl Kinases, Banyuhay Paningbatan Serrano Jan 2018

The Molecular Basis Of Caspase-9 Inactivation By Pka And C-Abl Kinases, Banyuhay Paningbatan Serrano

Doctoral Dissertations

Caspases are the cysteine proteases that facilitate the fundamental pathway of programmed cell death or apoptosis. The activation and function of these powerful enzymes are tightly regulated to ensure the faithful execution of apoptosis and prevent untimely cell death. Many deadly human diseases such as cancer, neurodegeneration and autoimmune disorders have been associated with defective activation and faulty regulation of caspases. As such, caspases are considered as attractive drug targets, which when properly controlled, can lead to effective therapeutics for apoptosis-related diseases. Thus, comprehensive investigations of the structure, function and regulation of caspases are necessary to understand the complex mechanisms ...


Vibrated Squares As Equilibrium And Active Matter, Lee Askew Walsh Jan 2018

Vibrated Squares As Equilibrium And Active Matter, Lee Askew Walsh

Doctoral Dissertations

We study the effects of particle shape and self-propulsion on the collective behaviors of a two-dimensional granular fluid, using an experimental system of hard square grains. We energize the system by vibration, which, depending on particle shape, induces either isotropic diffusion or persistent self-propulsion in the particles. We use specially designed grains as a model system to study (i) the equilibrium packing of hard squares in two dimensions, (ii) the dynamics of athermal self-propelled particles, and (iii) the melting kinetics of an unconfined granular crystallite.

The first study concerns the phase diagram of a two-dimensional fluid of hard squares, which ...


3' End Additions By T7 Rna Polymerase Are Rna Self-Templated, Distributive And Diverse In Character––Rna-Seq Analyses, Yasaman Gholamalipour, Aruni K. Mudiyanselage, Craig T. Martin Jan 2018

3' End Additions By T7 Rna Polymerase Are Rna Self-Templated, Distributive And Diverse In Character––Rna-Seq Analyses, Yasaman Gholamalipour, Aruni K. Mudiyanselage, Craig T. Martin

Chemistry Department Faculty Publication Series

Synthetic RNA is widely used in basic science, nanotechnology and therapeutics research. The vast majority of this RNA is synthesized in vitro by T7 RNA polymerase or one of its close family members. However, the desired RNA is generally contaminated with products longer and shorter than the DNA-encoded product. To better understand these undesired byproducts and the processes that generate them, we analyze in vitro transcription reactions using RNA-Seq as a tool. The results unambiguously confirm that product RNA rebinds to the polymerase and self-primes (in cis) generation of a hairpin duplex, a process that favorably competes with promoter driven ...


Mapping Sandbars In The Connecticut River Watershed Through Aerial Images For Floodplain Conservation, Bogumila Backiel Jan 2018

Mapping Sandbars In The Connecticut River Watershed Through Aerial Images For Floodplain Conservation, Bogumila Backiel

Masters Theses

Active geomorphic features of rivers like sandbars provide habitat for endangered and threatened riparian plant and animal species. However, human development has altered flow and sediment regimes, thus impairing formation of sandbars and islands. Large scale mapping of the fluvial geomorphology in river ecosystems like the Connecticut River is are necessary to understand the dynamics of these features and preserve habitat. Orthophotographs from 2012 from United States Department of Agriculture's Farm Service Agency (FSA), National Agriculture Imagery Program (NAIP) were used to develop a model in ArcGIS Pro to identify fluvial geomorphic features in the Connecticut River and 12 ...


Designing Sustainable Landscapes: Biomass Settings Variable, Kevin Mcgarigal, Brad Compton, Ethan Plunkett, Bill Deluca, Joanna Grand Jan 2018

Designing Sustainable Landscapes: Biomass Settings Variable, Kevin Mcgarigal, Brad Compton, Ethan Plunkett, Bill Deluca, Joanna Grand

Data and Datasets

Vegetation biomass is an effective descriptor of the net primary productivity of an ecosystem. As such, it is a fundamental component of the ecosystem's trophic dynamics. In addition, vegetation biomass is an effective proxy for the successional development (or seral stage) of vegetation following a disturbance. Biomass is one of several ecological settings variables that collectively characterize the biophysical setting of each 30 m cell at a given point in time (McGarigal et al 2017). Specifically, biomass measures the estimated above-ground live biomass (Mg/ha) of undeveloped forested (including forested wetlands) cells in 2010 based primarily on a spectral ...


Vitamin D Status Is Not Associated With Risk Of Early Menopause, Alexandra C. Purdue-Smith, Brian W. Whitcomb, Joann E. Manson, Susan E. Hankinson, Lisa M. Troy, Bernard A. Rosner, Elizabeth R. Bertone-Johnson Jan 2018

Vitamin D Status Is Not Associated With Risk Of Early Menopause, Alexandra C. Purdue-Smith, Brian W. Whitcomb, Joann E. Manson, Susan E. Hankinson, Lisa M. Troy, Bernard A. Rosner, Elizabeth R. Bertone-Johnson

Biostatistics and Epidemiology Faculty Publications Series

Background: Early natural menopause, the cessation of ovarian function before age 45 y, is positively associated with cardiovascular disease and other conditions. Dietary vitamin D intake has been inversely associated with early menopause; however, no previous studies have evaluated risk with regard to plasma 25-hydroxyvitamin D [25(OH)D] concentrations.

Objective: We prospectively evaluated associations of total and free 25(OH)D and vitamin D–binding protein (VDBP) concentrations and the risk of early menopause in a case-control study nested within the Nurses’ Health Study II (NHS2). We also considered associations of 25(OH)D and VDBP with anti-Müllerian hormone ...


The Importance Of Friends And Family To Recreational Gambling, At-Risk Gambling, And Problem Gambling, Alissa Mazar, Robert J. Williams, Edward J. Stanek Iii, Martha Zorn, Rachel A. Volberg Jan 2018

The Importance Of Friends And Family To Recreational Gambling, At-Risk Gambling, And Problem Gambling, Alissa Mazar, Robert J. Williams, Edward J. Stanek Iii, Martha Zorn, Rachel A. Volberg

Biostatistics and Epidemiology Faculty Publications Series

Background

The variables correlated with problem gambling are routinely assessed and fairly well established. However, problem gamblers were all ‘at-risk’ and ‘recreational’ gamblers at some point. Thus, it is instructive from a prevention perspective to also understand the variables which discriminate between recreational gambling and at-risk gambling and whether they are similar or different to the ones correlated with problem gambling. This is the purpose of the present study.

Method

Between September 2013 to May 2014, a representative sample of 9,523 Massachusetts adults was administered a comprehensive survey of their past year gambling behavior and problem gambling symptomatology. Based ...
