At present, an energy transition consistent with achieving the goals set out by the Paris climate agreement is not occurring, primarily due to lock-in dynamics at the societal and energy business complex level. To contribute to discussions on how to unlock a major system transformation, we introduce here a new framework that characterises the energy business as a system and traces its metabolism. Drawing analogies with biology and using metabolic maps, we present a systems analysis...

Microprocessors are traditionally designed to provide best overall performance across a wide range of applications and operating environments. Several groups have proposed hardware techniques that save energy by downsizing hardware resources that are underutilized by the current application phase. Others have proposed a different energy-saving approach: dividing the processor into domains and dynamically changing the clock frequency and voltage within each domain during phases when the full...

System of Systems (SoS) development is a complex process that depends on the cooperation of various independent Systems. SoS acquisition and development differs from that typical for a single System; it has been shown to follow a wave paradigm known as the Wave Model. Agent based models (ABMs) consist of a set of abstracted entities referred to as agents, and a framework using simplified rules for simulating agent decisions and interactions. Agents have their own goals and are capable of...

In this project, ATC-NY is developing methods for evaluating anomalous behavior concurrently with reacting to it. Anomalous events that are not so suspicious as to cause an immediate alarm are continually reexamined in the light of later events, with the goal of eventually understanding whether they are benign or malign. As time goes on, the IDS should become familiar with common attacks, even while it continually adapts to small changes in normal behavior. By focusing on the long-term problem...

A major issue in modeling and computation is how to handle high dimensional problems. We can divide these high dimensional problems into two classes: Moderately high dimensional problems or very high dimensional problems. In the former class, we have problems such as the Boltzmann equation, whose dimensionality is high but they are still amendable to grid-based methods. In the latter class we have problems such as exploration of the configuration space of a large molecule. These problems often...

This paper proposes a new approach to multi-agent systems leveraging from recent advances in networking and reinforcement learning to scale up teamwork based on joint intentions. In this approach, teamwork is subsumed by the coordination of learning agents. The intuition behind this approach is that successful coordination at the global level generates opportunities for teamwork interactions at the local level and vice versa. This unique approach scales up model-based teamwork theory with an...

The segmentation of a text into sentences is a necessary prerequisite for many natural language processing tasks, including part-of-speech tagging and sentence alignment. This is a non-trivial task, however, since end-of-sentence punctuation marks are ambiguous. A period, for example, can denote a decimal point, an abbreviation, the end of a sentence, or even an abbreviation at the end of a sentence. To disambiguate punctuation marks most systems use brittle, special-purpose regular expression...

This paper is about an approach to the flexible utilization of old plans called adaptive planning. An adaptive planner can take advantage of the details associated with specific plans, while still maintaining the flexibility of a planner that works from general plans. Key elements in the theory of adaptive planning are its treatment of background knowledge and the introduction of a notion of planning by situation matching. This paper will discuss a theory of adaptive planning as it applies to...

Unstructured methods for region discretization have become common in computational fluid dynamics (CFD) analysis because of certain benefits they have over structured meshes (where the discretization of the domain reflects some type of consistent geometrical regularity). Unstructured meshes are powerful tools for efficiently defining complex geometries and also lend themselves to analysis techniques such as adaptive mesh refinement (AMR) where the properties of the mesh adapt to the properties...

Extant literature has addressed empirical insurgent networks inadequately, insufficiently accounting for insurgent warfare's unique characteristics. Specifically, existing structural studies of insurgencies—those seeking to understand emergent social system patterns—have failed to capture the overlapping nature of competing, information-sharing networks in such contexts. This study focuses on the ways by which insurgent and authority social networks co-evolve in insurgent warfare. It...

The recently-proposed theory of distilled sensing establishes that adaptivity in sampling can dramatically improve the performance of sparse recovery in noisy settings. In particular, it is now known that adaptive point sampling enables the detection and/or support recovery of sparse signals that are otherwise too weak to be recovered using any method based on non-adaptive point sampling. In this paper the theory of distilled sensing is extended to highly-undersampled regimes, as in compressive...
