Foundational Concepts in Simulation-Based Resilience Analysis and Design

Resilience is a topic of increasing interest–with ever-present calls from policymakers to increase the resilience of complex systems and infrastructure. However, resilience as a concept can be confusing, because of a lack of a common unified definition and frame of reference. Sometimes it can appear as if resilience analysis is merely duplicating other, more mature fields such as safety, reliability, or risk, while other times it seems as if resilience is providing an “alternative” view with limited rigor. To better understand the resilience concept (and its relation to the broader field of risk management), this paper will present the perspective of simulation-based resilience analysis and design, including some of the foundational precepts and resultant concepts defining the resilience concept. It will further present the motivation for using simulation to understand resilience and highlight some ongoing work and research challenges in this area. From this frame of reference, one can better understand the field of resilience, including how different aspects and definitions of resilience relate to each other, and how resilience relates to broader design considerations and practices.

David Blackwell’s Forty Years in the Idaho Desert, The Foundation for 21st Century Geothermal Research

Dr. David Blackwell has had a profound influence on geo-thermal exploration and R&D in Idaho. Forty years have elapsed since the first Southern Methodist University (SMU) temperature logging truck rolled onto the high desert in Southern Idaho, yet even after so much time has elapsed, most recent and ongoing geothermal R&D can trace its roots to the foundational temperature studies led by Dr. Blackwell. We believe that the best way to honor any scientist is to see their work carried forward by others. As this paper demonstrates, it has been an easy task to find a host of Idaho researchers and students eager to contribute to this tribute paper. We organize this paper by ongoing or recent projects that continue to benefit left to Idaho by Dr. David Blackwell.

A streamlined build system foundation for developing HPC software

BLT bundles custom CMake macros, unit testing frameworks for C++ and Fortran, and a set of smoke tests for common HPC dependencies. The combination of these three provides a foundation for quickly bootstrapping a CMale-based system for developing HPC softward.

The HEP Software Foundation Community

The HEP Software Foundation was founded in 2014 to tackle common problems of software development and sustainability for high-energy physics. In this paper we outline the motivation for the founding of the organisation and give a brief history of its development. We describe how the organisation functions today and what challenges remain to be faced in the future.

An Agenda for Multimodal Foundation Models for Earth Observation

Archives of remote sensing (RS) data are increasing swiftly as new sensing modalities with enhanced spatiotemporal resolution become operational. While promising new breakthroughs, the sheer volume of RS archives stretches the limits of human analysts and existing AI tools, as most models are: i) limited to single data modalities; ii) task-specific; iii) heavily reliant on labeled data. The emerging Foundation Models (FMs) have the potential to address these limitations. Trained on vast unlabeled datasets through self-supervised learning, FMs enable generic feature extraction that facilitate specialization to a wide variety of downstream tasks. This paper describes a vision towards an FM for multimodal Earth Observation data (FM4EO), discussing key building blocks and open challenges. We put particular emphasis on multimodal reasoning, a topic underexplored in EO. Our ultimate goal is a practical path toward FM4EO with capacity to unlock breakthroughs in few-shot learning scenarios, multimodal geographic knowledge integration, synthesis, and hypothesis generation.

CRITICAL FUNCTION ASSURANCE: Understanding Critical Function and Critical Function Delivery is Foundational for Meaningful ICS Security Improvement and Policy Efforts

Modern life is enabled by a complex and interdependent web of critical functions, including energy, communications, transportation, food, and water. Automation has significantly reduced or replaced human interactions in the delivery of these functions, resulting in a web of goods and services that are made available 24/7 only through unique and intentional deployments of microprocessors, software, and firmware technologies. The prospect of cyber-enabled sabotage of these processes disrupts traditional risk determination models. Critical Function Assurance (CFA) is a foundational approach to identifying, prioritizing, and mitigating the risk that is inherent in the delivery of critical functions that depend on digital technology. It provides rapid focus to what matters most and illuminates elements and areas of risk that otherwise are often overlooked. This focus enables effective application of available security resources and optimizes security strategy and policy efforts. This paper introduces CFA to decision makers and risk executives (including CEOs, COOs, CFOs, and CISOs) whose organizations support and deliver the critical functions that underpin national defense, societal health and safety, and a vibrant economy.

Powering the Blue Economy: Foundational Research and Development

With increased use of the oceans for transportation, extraction of food, fibre, and minerals, recreation and tourism, and other blue economy industries, there is a need for additional power at sea. In the face of climate change, the increased power must come from renewable sources; often marine energy is the most energy-dense power source available. But we have little experience with adapting wave and tidal devices from large scale grid power to the specialized and small devices needed to power blue economy applications, nor the engineering solutions to support codesign of emerging marine industries. As directed by the U.S. Department of Energy (DOE), two DOE national laboratories have developed foundational research and development projects to replace conventional power or batteries at sea (ocean observation platforms), emerging industry power needs (offshore aquaculture operations), as well as examining common challenges for using marine power (efficient power systems, minimizing interference, optimizing materials and manufacturing).
