Coping with the Bounds: a Neo-Clausewitzean Primer / Thomas J
About the CCRP The Command and Control Research Program (CCRP) has the mission of improving DoD’s understanding of the national security implications of the Information Age. Focusing upon improving both the state of the art and the state of the practice of command and control, the CCRP helps DoD take full advantage of the opportunities afforded by emerging technologies. The CCRP pursues a broad program of research and analysis in information superiority, information operations, command and control theory, and associated operational concepts that enable us to leverage shared awareness to improve the effectiveness and efficiency of assigned missions. An important aspect of the CCRP program is its ability to serve as a bridge between the operational, technical, analytical, and educational communities. The CCRP provides leadership for the command and control research community by: • articulating critical research issues; • working to strengthen command and control research infrastructure; • sponsoring a series of workshops and symposia; • serving as a clearing house for command and control related research funding; and • disseminating outreach initiatives that include the CCRP Publication Series. This is a continuation in the series of publications produced by the Center for Advanced Concepts and Technology (ACT), which was created as a “skunk works” with funding provided by the CCRP under the auspices of the Assistant Secretary of Defense (NII). This program has demonstrated the importance of having a research program focused on the national security implications of the Information Age. It develops the theoretical foundations to provide DoD with information superiority and highlights the importance of active outreach and dissemination initiatives designed to acquaint senior military personnel and civilians with these emerging issues. -

DfX-Symposium 2021 Synthetic Data Generation for Deep Learning Models Christoph Petroll 1 , 2 , Martin Denk 2 , Jens Holtmannspötter 1 ,2, Kristin Paetzold 3 , Philipp Höfer 2 1 The Bundeswehr Research Institute for Materials, Fuels and Lubricants (WIWeB) 2 Universität der Bundeswehr München (UniBwM) 3 Technische Universität Dresden * Korrespondierender Autor: Christoph Petroll Institutsweg 1 85435 Erding Germany Telephone: 08122/9590 3313 Mail: [email protected] Abstract The design freedom and functional integration of additive manufacturing is increasingly being implemented in existing products. One of the biggest challenges are competing optimization goals and functions. This leads to multidisciplinary optimization problems which needs to be solved in parallel. To solve this problem, the authors require a synthetic data set to train a deep learning metamodel. The research presented shows how to create a data set with the right quality and quantity. It is discussed what are the requirements for solving an MDO problem with a metamodel taking into account functional and production-specific boundary conditions. A data set of generic designs is then generated and validated. The generation of the generic design proposals is accompanied by a specific product development example of a drone combustion engine. Keywords Multidisciplinary Optimization Problem, Synthetic Data, Deep Learning © 2021 die Autoren | DOI: https://doi.org/10.35199/dfx2021.11 1. Introduction and Idea of This Research Due to its great design freedom, additive manufacturing (AM) shows a high potential of functional integration and part consolidation [1]-[3]. For this purpose, functions and optimization goals that are usually fulfilled by individual components must be considered in parallel. -

Kuijper (TNO Defence, Security and Safety) University of Twente Cluster: Human Media Interaction (HMI) Department of Electrical Engineering, Mathematics and Computer Science (EEMCS) Abstract Currently, during the creation of a simulator that uses Virtual Reality, 3D content creation is by far the most time consuming step, of which a large part is done by hand. This is no different for the creation of virtual urban environments. In order to speed up this process, city generation systems are used. At re-lion, an overall design was specified in order to implement such a system, of which the first step is to automatically create realistic city boundaries. Within the scope of a research project for the University of Twente, an algorithm is proposed for this first step. This algorithm makes use of two-dimensional Perlin noise to fill a grid with random values. After applying a transformation function, to ensure a minimum amount of clustering, and a threshold mech- anism to the grid, the hull of the resulting shape is converted to a vector representation. -
CMSC 425: Lecture 14 Procedural Generation: Perlin Noise
CMSC 425 Dave Mount CMSC 425: Lecture 14 Procedural Generation: Perlin Noise Reading: The material on Perlin Noise based in part by the notes Perlin Noise, by Hugo Elias. (The link to his materials seems to have been lost.) This is not exactly the same as Perlin noise, but the principles are the same. Procedural Generation: Big game companies can hire armies of artists to create the immense content that make up the game's virtual world. If you are designing a game without such extensive resources, an attractive alternative for certain natural phenomena (such as terrains, trees, and atmospheric effects) is through the use of procedural generation. With the aid of a random number generator, a high quality procedural generation system can produce remarkably realistic models. Examples of such systems include terragen (see Fig. 1(a)) and speedtree (see Fig. 1(b)). terragen speedtree (a) (b) Fig. 1: (a) A terrain generated by terragen and (b) a scene with trees generated by speedtree. Before discussing methods for generating such interesting structures, we need to begin with a background, which is interesting in its own right. The question is how to construct random noise that has nice structural properties. In the 1980's, Ken Perlin came up with a powerful and general method for doing this (for which he won an Academy Award!). The technique is now widely referred to as Perlin Noise (see Fig. 2(a)). A terrain resulting from applying this is shown in Fig. 2(b). (The terragen software uses randomized methods like Perlin noise as a starting point for generating a terrain and then employs additional operations such as simulated erosion, to achieve heightened realism.) Perlin Noise: Natural phenomena derive their richness from random variations. -
State of the Art in Procedural Noise Functions
EUROGRAPHICS 2010 / Helwig Hauser and Erik Reinhard STAR – State of The Art Report State of the Art in Procedural Noise Functions A. Lagae1,2 S. Lefebvre2,3 R. Cook4 T. DeRose4 G. Drettakis2 D.S.

Zwicker8 1Katholieke Universiteit Leuven 2REVES/INRIA Sophia-Antipolis 3ALICE/INRIA Nancy Grand-Est / Loria 4Pixar Animation Studios 5Purdue University 6Weta Digital 7New York University 8University of Bern Abstract Procedural noise functions are widely used in Computer Graphics, from off-line rendering in movie production to interactive video games. The ability to add complex and intricate details at low memory and authoring cost is one of its main attractions. This state-of-the-art report is motivated by the inherent importance of noise in graphics, the widespread use of noise in industry, and the fact that many recent research developments justify the need for an up-to-date survey. Our goal is to provide both a valuable entry point into the field of procedural noise functions, as well as a comprehensive view of the field to the informed reader. In this report, we cover procedural noise functions in all their aspects. We outline recent advances in research on this topic, discussing and comparing recent and well established methods. We first formally define procedural noise functions based on stochastic processes and then classify and review existing procedural noise functions. We discuss how procedural noise functions are used for modeling and how they are applied on surfaces. We then introduce analysis tools and apply them to evaluate and compare the major approaches to noise generation. -
Tile-Based Method for Procedural Content Generation
Tile-based Method for Procedural Content Generation Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By David Maung Graduate Program in Computer Science and Engineering The Ohio State University 2016 Dissertation Committee: Roger Crawfis, Advisor; Srinivasan Parthasarathy; Kannan Srinivasan; Ken Supowit Copyright by David Maung 2016 Abstract Procedural content generation for video games (PCGG) is a growing field due to its benefits of reducing development costs and adding replayability. While there are many different approaches to PCGG, I developed a body of research around tile-based approaches. Tiles are versatile and can be used for materials, 2D game content, or 3D game content. They may be seamless such that a game player cannot perceive that game content was created with tiles. Tile-based approaches allow localized content and semantics while being able to generate infinite worlds. Using techniques such as aperiodic tiling and spatially varying tiling, we can guarantee these infinite worlds are rich playable experiences. My research into tile-based PCGG has led to results in four areas: 1) development of a tile-based framework for PCGG, 2) development of tile-based bandwidth limited noise, 3) development of a complete tile-based game, and 4) application of formal languages to generation and evaluation models in PCGG. ii Vita 2009................................................................B.S.
