Policy Changes Impact In Deforestation Of The Brazilian Amazon, Iara Silva Jaques

Master's Projects and Capstones

Since discovered and inhabited, the Brazilian Amazon has been explored and impacted negatively by human activities. The conversion of forest to pastureland and farmland, as well as mining activities, road opening, wood and ore extraction and fire are historically the main causes of environmental damages and forest loss in the region. This project overviewed the latest changes in environmental policy and practices towards environmental protection conducted by the Brazilian president Jair Bolsonaro, since he took office in 2019, and analyzed the progress of deforestation in the recent years under the new federal administration. Geographic Information System analysis were used to …

Integrated Resource Plan For Portland General Electric (Pge), Mary Biswal, Alejandro Castelan

Master's Projects and Capstones

An integrated resource plan (IRP) for Portland General Electric (PGE) is developed in this master’s project. The IRP is based on capacity expansion modeling for zero-carbon emission scenarios. PGE is a public electric utility based in Oregon and serves around 887,000 customers across a territory of 4,000 sq. miles. The utility’s resource mix is currently heavily dependent on natural gas making up almost 50% of its capacity. While the state renewable portfolio standards (RPS) require Oregon power utilities to derive 50% of their generation from renewable sources by 2040, PGE plans to move rapidly into a clean energy mix by …

An Integrated Resource Plan For Arizona Public Service Electric (Aps), Irene Boghdadi, Randy Chiu

Master's Projects and Capstones

Our Masters Capstone Project is an Integrated Resource Plan (IRP) for Arizona’s largest electric utility, Arizona Public Service Electric (APS).

An IRP is developed by utilities to identify the optimal combination of demand- and supply-side resources needed to reliably meet forecasted demand for energy and capacity, including a planning reserve margin, over a future period.

In addition to APS’s obligation to serve the growing load in Arizona while minimizing costs, it is required by the state to adhere to the Renewable Energy Standard (RES) policy of 15 percent retail sales from renewable energy resources by 2025.

The analysis described in …

How Facets Of Work Illuminate Sociotechnical Challenges Of Industry 5.0, Steven Alter

Business Analytics and Information Systems

This conceptual contribution explains how the idea of “facets of work” can refocus traditional sociotechnical concerns to increase their relevance in increasingly automated and digitalized workplaces far removed from situations studied by early sociotechnical researchers. A background section summarizes how the sociotechnical approach seems pervasive but possibly outdated in some ways. It explains how the idea of “facets of work” emerged from attempting to bring richer, more evocative ide-as to systems analysis and design. Focusing on facets of work during initial discussions of requirements could provide guidance without jumping prematurely to precision and notation needed for producing technical artifacts. Tables …

Applying Facets Of Work As A Source Of Knowledge And Insight For Requirements Determination, Steven Alter

Business Analytics and Information Systems

This conceptual contribution explains how the idea of “facets of work” can bring more knowledge and richer, more evocative ideas to the development of system requirements in organizational settings. Focusing on facets of work potentially provides useful guidance without requiring unnecessary details, precision, and notation. A background section summarizes how the current research emerged from partial overlaps between separate research efforts. Table 1 identifies 18 facets of work. Five other tables look at a subset of the facets to illustrate concepts associated with specific facets, common success factors and tradeoffs, sub-facets and other topics. Use of the same subset of …
