Precise Energy Efficient Scheduling Of Mixed-Criticality Tasks & Sustainable Mixed-Criticality Scheduling, Sai Sruti

Masters Theses

"In this thesis, the imprecise mixed-criticality model (IMC) is extended to precise scheduling of tasks, and integrated with the dynamic voltage and frequency scaling (DVFS) technique to enable energy minimization. The challenge in precise scheduling of MC systems is to simultaneously guarantee the timing correctness for all tasks, hi and lo, under both pessimistic and optimistic (less pessimistic) assumptions. To the best of knowledge this is the first work to address the integration of DVFS energy conserving techniques with precise scheduling of lo-tasks of the MC model.

In this thesis, the utilization based schedulability tests and sufficient conditions for such …

Planning Cities, Economically Or Communally: A Comparative Study Of Amsterdam And San Francisco, Raina Dawn Whittekiend

Master's Theses

Globalization has spun “community” off its axis. What once defined community is no longer the current state of the community. Increased economic transactions have led to the instability of communities that once depended on one another at the local level. These communities are now dependent on systems that do not know nor understand their actors. This lack of relationship between development and subject is witnessed and highly scrutinized in developing countries all over the world and has been intensely researched in academic literature. This thesis intends to better understand why in modernized global cities these same processes of development and …

Arts-Based Education For Enchanting, Embodied And Embedded Sustainability, Hans Dieleman

Artizein: Arts and Teaching Journal

This article sketches two contrasting ideal-typical narratives of sustainability, a disenchanting and an enchanting one, and argues that current thinking in sustainability is mainly situated in the narrative of disenchantment. This narrative is based on various obsolete philosophical assumptions, and hampers the transformation process, as it distances the population from being part of this. It then sketches the narrative of enchanting sustainability and shows how this has the capacity to engage, intrigue and motivate people to be involved. It is rooted in an arts-based approach of connecting aesthetics, associative thinking, reflective practice, emotion-based working, aspiration and intentionality. The article moves …

A Framework For Incorporating The Impact Of Water Quality On Water Supply Stress: An Example From Louisiana, David M. Borrok, Jian Chen, Hisham Eldardiry, Emad Habib

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Water of poor quality can directly impact the budget of water available for key user groups. Despite this importance, methods for quantifying the impact of water quality on water availability remain elusive. Here, we develop a new framework for incorporating the impact of water quality on water supply by modifying the Water Supply Stress Index (WaSSI). We demonstrate the usefulness of the framework by investigating the impact of high salinity waters on the availability of irrigation water for agriculture in Louisiana. The WaSSI was deconstructed into sectoral components such that the total available water supply could be reduced for a …

Sustainability For Whom? Place-Makers Of Detroit, Dominica, Ecuador, And Mexico, Emma Gaalaas Mullaney

Sponsored Events -- List

Drawing from more than a decade of work with farmers in rural and urban areas across the Americas, Professor Gaalaas Mullaney highlights some key findings about how small-scale farmers have a big influence on the conservation of cultural and ecological richness in their region. In each of these diverse places, innovative farmers work at the margins of dominant political and economic institutions with only occasional recognition of the value that they produce. What can these farmers teach us about how to cultivate place-based sustainability? How is sustainability related to social and economic justice?

Reconciling The Challenge Of Aphanic Species Within Marine Conservation, Kerri L. Bolow

HCNSO Student Capstones

Aphanic species are those within a taxonomic complex that may not be readily distinguishable from other sympatric species. The existence of these species is becoming apparent at an increasing rate through the use of technological tools like molecular genetic analyses. A lack of clarity on the definitions of terms used to describe similar species, how these species are identified, and how prevalent they are can confound identification, description, and management of these organisms. This review collects and defines the terms used to describe these hidden species and suggests the use of the term aphanic for situations where additional information (and …
