Claytronics - a Synthetic Reality D.Abhishekh, B.Ramakantha Reddy, Y.Vijaya Kumar, A.Basi Reddy
International Journal of Scientific & Engineering Research, Volume 4, Issue 3, March‐2013 ISSN 2229‐5518 Claytronics - A Synthetic Reality D.Abhishekh, B.Ramakantha Reddy, Y.Vijaya Kumar, A.Basi Reddy, Abstract— "Claytronics" is an emerging field of electronics concerning reconfigurable nanoscale robots ('claytronic atoms', or catoms) designed to form much larger scale machines or mechanisms. Also known as "programmable matter", the catoms will be sub-millimeter computers that will eventually have the ability to move around, communicate with each others, change color, and electrostatically connect to other catoms to form different shapes. Claytronics technology is currently being researched by Professor Seth Goldstein and Professor Todd C. Mowry at Carnegie Mellon University, which is where the term was coined. According to Carnegie Mellon's Synthetic Reality Project personnel, claytronics are described as "An ensemble of material that contains sufficient local computation, actuation, storage, energy, sensing, and communication" which can be programmed to form interesting dynamic shapes and configurations. Index Terms— programmable matter, nanoscale robots, catoms, atoms, electrostatically, LED, LATCH —————————— —————————— 1 INTRODUCTION magine the concept of "programmable matter" -- micro- or which are ringed by several electromagnets are able to move I nano-scale devices which can combine to form the shapes of around each other to form a variety of shapes.

Considerations and Simulations About Pulse Detonation Engine
MATEC Web of Conferences 290, 04009 (2019) https://doi.org/10.1051/matecconf /2019290 04009 MSE 2019 Considerations and simulations about Pulse Detonation Engine Vasile Prisacariu1,*, Constantin Rotaru1, and Mihai Leonida Niculescu2 1Henri Coandă Air Force Academy, Aviation Department, Brașov, Romania 2INCAS, Aerodynamic Department, București, Romania Abstract. PDE propulsion can work from a subsonic regime to hypersonic regimes; this type of engine can have higher thermodynamic efficiency compared to other turbojet or turbofan engines due to the removal of rotating construction elements (compressors and turbines) that can reduce the mass and total cost of propulsion system. The PDE experimental researches focused on both the geometric configuration and the thermo- gas-dynamic flow aspects to prevent uncontrolled self-ignition. This article presents a series of numerical simulations on the functioning of PDE with hydrogen at supersonic regimens.

However, this concept of running the propulsion systems involves difficulties both in rapidly achieving the fuel mixture at high speeds and in initiating and sustaining detonation in a controlled manner. PDE differs from conventional propulsion systems in two main aspects: it generates an intermittent pulse and produces high pressure increase in the combustion chamber, which also represents a major advantage of a PDE, see Figure 1. -

Study and Numerical Simulation of Unconventional Engine Technology
STUDY AND NUMERICAL SIMULATION OF UNCONVENTIONAL ENGINE TECHNOLOGY by ANJALI SHEKHAR B.E Aeronautical Engineering VTU, Karnataka, 2013 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science, Aerospace Engineering, College of Engineering and Applied Science, University of Cincinnati, Ohio 2018 Thesis Committee: Chair: Ephraim Gutmark, Ph.D. Member: Shaaban Abdallah, Ph.D. Member: Mark Turner, Sc.D. An Abstract of Study and Numerical Simulation of Unconventional Engine Technology by Anjali Shekhar Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Aerospace Engineering University of Cincinnati December 2018 The aim of this thesis is to understand the working of two unconventional aircraft propul- sion systems and to setup a two-dimensional transient simulation to analyze its operational mechanism. The air traffic has nearly increased by about 40% in past three decades and calls for alternative propulsion techniques to replace or support the current traditional propulsion methodology. In the light of current demand, the thesis draws motivation from renewed inter- est in two non-conventional propulsion techniques designed in the past and had not been given due importance due to various flaws/drawbacks associated. The thesis emphasizes on the work- ing of Von Ohains thermal compression engine and pulsejet combustors. Computational Fluid Dynamics is used in current study as it offers very high flexibility and can be modified easily to incorporate the required changes. Thermal Compression engine is a design suggested by Von Ohain in 1948. The engine works on the principle of pressure rise caused inside the engine which completely depends on the temperature of working fluid and independent of rotations per minute. -
Pairbot: a Novel Model for Autonomous Mobile Robot Systems
Pairbot:ANOVEL MODEL FOR AUTONOMOUS MOBILE ROBOT SYSTEMS CONSISTING OF PAIRED ROBOTS APREPRINT Yonghwan Kim Yoshiaki Katayama Koichi Wada Department of Computer Science Department of Computer Science Department of Applied Informatics Nagoya Institute of Technology Nagoya Institute of Technology Hosei University Aichi, Japan Aichi, Japan Tokyo, Japan [email protected] [email protected] [email protected] October 1, 2020 ABSTRACT Programmable matter consists of many self-organizing computational entities which are autonomous and cooperative with one another to achieve a goal and it has been widely studied in various fields, e.g., robotics or mobile agents, theoretically and practically. In the field of computer science, programmable matter can be theoretically modeled as a distributed system consisting of simple and small robots equipped with limited capabilities, e.g., no memory and/or no geometrical coordination. A lot of theoretical research is studied based on such theoretical models, to clarify the relation between the solvability of various problems and the considered models. We newly propose a computational model named Pairbot model where two autonomous mobile robots operate as a pair on a grid plane. In Pairbot model, every robot has the one robot as its unique partner, called buddy, each other. We call the paired two robots pairbot. Two robots in one pairbot can recognize each other, and repeatedly change their geometrical relationships, long and short, to achieve the goal. In this paper, as a first step to show the feasibility and effectiveness of the proposed Pairbot model, we introduce two simple problems, the marching problem and the object coating problem, and propose two algorithms to solve these two problems, respectively. -
