Maturity Model For Customer-Centric Approach In Enterprise: The Case Of E-Commerce And Online Retail Industry, Soheil Zarrin

Dissertations and Theses

The network technologies are changing the dynamics of the interaction between customer and provider. Customers demand closer relationships and higher investment between partners, as well as cooperation between companies to build supporting technologies for their unique needs. Customer-centricity is defined as interaction with the customer through various touchpoints and aggregating these relations to create a position for the customer. Each Customer has a different need and expectation from the provider or seller, and companies need to be flexible enough to fulfill their needs. One of the reasons organizations invest less in customer experience is that they believe they are already …

Environmental Decision Support Systems As A Service: Demonstration On Ce-Qual-W2 Model, Yoav Bornstein, Ben Dayan, Amir Cahn, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

An environmental decision support system (EDSS) can be used as an important tool for the rehabilitation and preservation of ecosystems. Nonetheless, high assimilation costs (both money and time) are one of the main reasons these tools are not widely adopted in practice. This work presents a low-cost paradigm of “EDSS as a Service.” This paradigm is demonstrated for developing a water quality EDSS as a service that utilizes the well-known CE-QUAL-W2 model as a kernel for deriving optimized decisions. The paradigm is leveraging new open-source technologies in software development (e.g., Docker, Kubernetes, and Helm) with cloud computing to significantly reduce …

Secondary Motions Above A Staggered Multi-Scale Rough Wall, Bianca Viggiano, Juliaan Bossuyt, N. Ali, Johan Meyers, Raul Bayoan Cal

Mechanical and Materials Engineering Faculty Publications and Presentations

Wind tunnel experiments were performed to investigate turbulent flow over an array of heterogeneous roughness elements using stereoscopic particle image velocimetry. Nine streamwise planes, covering one periodic cell of a multi-scale roughness element that is arranged in a staggered pattern, are combined to quantify mean flow features and Reynolds stresses. Dispersive stresses, arising from spatial variations in the temporally averaged mean velocity, are also presented. The results highlight that the roughness elements create a large deficit pathway along the surfaces. Outer scaling of the time-averaged streamwise velocity presents features which are nearly independent of the roughness element type, with parameters …

Site-Specific Site Response Analysis And Cascadia Subduction Zone Ground Motions Evaluation For A Site Near Portland, Brian Ackerman

Civil and Environmental Engineering Master's Project Reports

Site-specific ground motions, site-specific site response analysis, and development of site-specific acceleration ground spectra at the ground surface was developed per ASCE 7-10 for the Kirkland Renaissance Boardwalk, a site in Vancouver, Washington.

Synthetic broadband ground motions developed specifically for Cascadia Subduction Zone (CSZ) megathrust earthquake were used for site-response analysis. The results of site-specific site response analyses using the strong motions were compared with the results from the 5 motions considered for the ASCE 7-10 procedure. The effect of motion duration and other ground motion intensity measures on the results of the site-specific site response analysis was investigated.

Measuring Volatile Emissions From Moss Gametophytes: A Review Of Methodologies And New Applications, Danlyn L. Brennan, Leslie M. Kollar, Scott Kiel, Timea Deakova, Aurélie Laguerre, Stuart F. Mcdaniel, Sarah Eppley, Elliott T. Gall, Todd Rosenstiel

Center for Life in Extreme Environments Publications

Mosses inhabit nearly all terrestrial ecosystems and engage in important interactions with nitrogen-fixing microbes, sperm-dispersing arthropods, and other plants. It is hypothesized that these interactions could be mediated by biogenic volatile organic compounds (BVOCs). Moss BVOCs may play fundamental roles in influencing local ecologies, such as biosphere–atmosphere–hydrosphere communications, physiological and evolutionary dynamics, plant–microbe interactions, and gametophyte stress physiology. Further progress in quantifying the composition, magnitude, and variability of moss BVOC emissions, and their response to environmental drivers and metabolic requirements, is limited by methodological and analytical challenges. We review several sampling techniques with various analytical approaches and describe best practices …

Extreme Winds Alter Influence Of Fuels And Topography On Megafire Burn Severity In Seasonal Temperate Rainforests Under Record Fuel Aridity, Cody Evers, Andres Holz, Sebastian Upton Busby, Max Nielsen-Pincus

Environmental Science and Management Faculty Publications and Presentations

Nearly 0.8 million hectares of land were burned in the North American Pacific Northwest (PNW) over two weeks under record-breaking fuel aridity and winds during the extraordinary 2020 fire season, representing a rare example of megafires in forests west of the Cascade Mountains. We quantified the relative influence of weather, vegetation, and topography on patterns of high burn severity (>75% tree mortality) among five synchronous megafires in the western Cascade Mountains. Despite the conventional wisdom in climate-limited fire regimes that regional drivers (e.g., extreme aridity, and synoptic winds) overwhelm local controls on vegetation mortality patterns (e.g., vegetation structure and …

Effects Of Electrode Negative Pulsing Ratio In Direct Energy Deposition Via Variable-Polarity Cold Metal Transfer Process On The Deposition Behavior And Microstructural Characteristics, Tae Hyun Lee, Cheolhee Kim, Minjung Kang

Mechanical and Materials Engineering Faculty Publications and Presentations

Interest in research on the application of variable-polarity cold metal transfer mode in wire-based direct energy deposition has been growing; particularly popular are investigations into the respective influences of polarity, amplitude of the arc current, and polarity variation sequence on the quality of the final product manufactured via additive manufacturing. The application of the electrode-negative phase is more capable of yielding relatively large droplets and increasing the weight of the deposited material. However, the proportions of the electrode positive phase are typically larger than those of the electrode-negative phase because it maintains arc stability and droplet transfer. This discrepancy has …

Embedded Librarian Shines A Light On "Grey Literature" For Informing Organizational Change, Tiffany Coulson

Online Northwest

As the use of “grey literature” becomes more accepted as a legitimate means of informing the implementation of timely research, librarians may become information resources much needed by grant writers, researchers, policy makers and innovative non-profits. Accessibility and timing are at issue for many change makers in a time where innovation and action are needed ahead of the constraints of academic research. This session will introduce ways in which organizational assessments may be quickly translated into real-time research which informs action. Real-world experiences in libraries and non-profits, accessible methodologies and resources for finding and citing non-traditional research will be presented.

An Aggregation-Based Nonlinear Multigrid Solver For Two-Phase Flow And Transport In Porous Media, Chak Shing Lee, Francois Hamon, Nicola Castelletto, Panayot S. Vassilevski, Joshua A. White

Mathematics and Statistics Faculty Publications and Presentations

A nonlinear multigrid solver for two-phase flow and transport in a mixed fractional-flow velocity-pressure-saturation formulation is proposed. The solver, which is under the framework of the full approximation scheme (FAS), extends our previous work on nonlinear multigrid for heterogeneous diffusion problems. The coarse spaces in the multigrid hierarchy are constructed by first aggregating degrees of freedom, and then solving some local flow problems. The mixed formulation and the choice of coarse spaces allow us to assemble the coarse problems without visiting finer levels during the solving phase, which is crucial for the scalability of multigrid methods. Specifically, a …

Design And Evaluation Of A Prototype Low-Damage Beam-Column Connection For Mass Timber Moment Frames, Samuel D. Richmann

Civil and Environmental Engineering Master's Project Reports

A moment-resisting, beam-column connection for mass timber moment frames was developed, designed and tested. The design was intended to limit damage to the timber members by creation of a ductile failure mechanism in steel U-shaped flexural plates (UFPs). Using design equations developed by previous research on UFPs by Baird, et al. (2014) as well as accepted design practices from the NDS and AISC, the components were sized to eliminate failure in the timber. The connection was tested using a quasi-static lateral displacement method following the procedure outlined in section K2.4b of AISC 341-16. A vertical load was placed on the …

University Honors Theses

This paper examines the relationship of narrative to computer games from a design perspective. Over the past three decades, the academic discourse on narratives games has evolved considerably while producing a wealth of serious scholarship. However, the process of narrative game design continues to be an underdeveloped area of study. In this thesis, I review influential scholarship on narrative games and the broader topic of interactive digital narrative (IDN) and attempt to analyze its potential application to the process of design. I examine some of the major works on IDN, explore historical and ongoing debates related to narrativity within games, …

Illustrating Ensemble Predictability Across Scales Associated With The 13–15 February 2019 Atmospheric River Event, Chad W. Hecht, Allison C. Michaelis, Andrew C. Martin, Jason M. Cordeira, Forest Cannon, F. Martin Ralph

Geography Faculty Publications and Presentations

The “Valentine’s Day” atmospheric river (AR) event that affected a majority of California during 13–15 February 2019 ranked as an AR3 (Ralph et al. 2019) along most of the California coast and reached AR4 intensity in Southern California. The strong onshore flow and dynamically favorable characteristics of the Valentine’s Day AR produced both an intense and long-duration precipitation event resulting in widespread hydrometeorological impacts across California. Palomar Observatory in northern San Diego County observed >10 in. (>254 mm) of precipitation in 24 h, the highest 24-h accumulation since record keeping began in 1943 (Hatchet et al. 2020
