The DIS architecture defines a time and space coherent representation of a virtual battlefield environment, measured in of the human perception and behaviors of warfighters interacting in free play. It provides a structure by which independently developed system may interact with each other in a well managed and validated combat simulation environment during all phases of the development process. A fundamental objective of the DIS architecture is to provide a blueprint to guide development of a general purpose system meeting the need of a wide range of users. The architecture must therefore support the broadest possible range of user needs. At the same time, the architecture and the associated standards must provide sufficient design definition to achieve the goal of transparent interoperability of a very wide range of simulators, simulations, and actual equipment operating on instrumented ranges.

Improvements and advances in the development of computer architecture now provide innovative technology for the recasting of traditional sequential solutions into high-performance, low-cost, parallel system to increase system performance. Research conducted in development of specialized computer architecture for the algorithmic execution of an avionics system, guidance and control problem in real time is described. A comprehensive treatment of both the hardware and software structures of a customized computer which performs real-time computation of guidance commands with updated estimates of target motion and time-to-go is presented. An optimal, real-time allocation algorithm was developed which maps the algorithmic tasks onto the processing elements. This allocation is based on the critical path analysis. The final stage is the design and development of the hardware structures suitable for the efficient execution of the allocated task graph. The processing element is designed for rapid execution of the allocated tasks. Fault tolerance is a key feature of the overall architecture. Parallel numerical integration techniques, tasks definitions, and allocation algorithms are discussed. The parallel implementation is analytically verified and the experimental results are presented. The design of the data-driven computer architecture, customized for the execution of the particular algorithm, is discussed.

Charge transport within Coulomb blockade regime in two-dimensional nanoparticle arrays exhibits nonlinear I-V characteristics, where the level of nonlinearity strongly associates with the array's architecture. Here, we use different mathematical approaches to quantify collective behavior in the charge transport inside the sample and its relationship to the structural characteristics of the assembly and the presence of charge disorder. In particular, we simulate single-electron tunneling conduction in several assemblies with controlled variation of the structural components (branching, extended linear segments) that influence the local communication among the conducting paths between the electrodes. Furthermore, by applying the fractal analysis of time series of the number of tunnelings and the technique of algebraic topology, we unravel the temporal correlations and structure of the phase-space manifolds corresponding to the cooperative fluctuations of charge. By tracking the I-V curves in different assemblies together with the indicators of collective dynamics and topology of manifolds in the state space, we show that the increased I-V nonlinearity is fully consistent with the enhanced aggregate fluctuations and topological complexity of the participating states. The architecture that combines local branching and global topological disorder enables the creation of large drainage basins of nano-rivers leading to stronger cooperation effects. Also, by determining shifts in the topology and collective transport features, we explore the impact of the size of electrodes and local charge disorder. The results are relevant for designing the nanoparticle devices with improved conduction; they also highlight the significance of topological descriptions for a broader understanding of the nature of fluctuations at the nanoscale.

While the standard AI algorithms we all know (and love?) look good on paper, we often run up against barriers when we put them into practice. Usually, these barriers occur when NP-Hard problems clash with limitations on memory and processing cycles. Add in the necessity to allow for the simple, expandable creation and management of behaviors, and the scope of the problem expands significantly. This lecture will show three different tricks for helping AI solve difficult problems while staying manageable. Dino Dini will show how co-routines can help mitigate the "polling problem" in AI behavior. Luke Dicken will show how complex behavior planning can be done off-line and spliced at run-time as necessary. Dave Mark will show his "infinite axis" utility system that allows for the simple design and processing of modular reasoners. All three sections will give concrete takeaways that can be applied to a variety of AI applications.

Architecture is about creating a place through physical design of buildings situated in space and in time. There is a dominant trend in the literature focusing on the relational aspects of space as well as of time. In that sense, Space and time are only relational attributes and not ontological categories in themselves. This essay argues, in line with Kant, that space and time are a priori notions, fundamental to a holistic understanding of situating buildings in spatio-temporal fields. The notion of place, as conceptualized by Aristotle, becomes an encompassing and meaningful totality. -- wagihyoussef.tumblr.com/
