Humankind on the Verge of Becoming a Spacefaring Civilization [chapter]

Giancarlo Genta
2013 Science and Fiction  
In the novel they are called replicators: a term introduced by Drexler 2 [18] for artificial self-replicating systems based on conventional large-scale technology and automation.  ...  As already stated, nothing is known about possible planets in the Gliese 250 system.  ...

A rigorous periodization of 'big' history

Robert Aunger
2007 Technological forecasting & social change  
Recent theory suggests that step-wise changes in the work accomplished by a system can be explained using steady-state non-equilibrium thermodynamics.  ...  Second, eras can also be defined within Earth history by differences in the scaling of energy flow improvement per NESST.  ...  Acknowledgements The author thanks Gillian Bentley, Eric Chaisson, David Christian, Val Curtis, Timothy Earle, Thomas Reydon, Peter Richerson, Miguel Rubio-Godoy, and Fred Spier for their comments on earlier  ...

Near-Term Self-replicating Probes – A Concept Design [article]

Olivia Borgue, Andreas M. Hein
2020 arXiv   pre-print
In this paper, we propose a concept for a partially self-replicating probe for space exploration based on current and near-term technologies, with a focus on small spacecraft.  ...  We conclude that small-scale, partially self-replicating probes are feasible near-term. Their benefits would play out in exploration missions requiring roughly more than a dozen of probes.  ...  Undeveloped AI systems constrain the scale of a self-replicating probe to a small-scale harvesting/manufacturing system manageable from Earth (Section 4.1).  ...

Location based placement of whole distributed systems

David Spence, Jon Crowcroft, Steven Hand, Tim Harris
2005 Proceedings of the 2005 ACM conference on Emerging network experiment and technology - CoNEXT'05  
To address these requirements we introduce and evaluate Xeno-Search, a new distributed service for selecting the machines to host components of multi-node distributed systems and which is uniquely able  ...  The XenoServer platform provides a distributed computing platform open to all and presents three major new challenges for resource discovery: Firstly, network location is key for effectively provisioning  ...  Acknowledgments We are grateful to the States of Jersey Education Department for funding the work of David Spence.  ...

A Thousand Earths: A Very Large Aperture, Ultralight Space Telescope Array for Atmospheric Biosignature Surveys

Dániel Apai, Tom D. Milster, Dae Wook Kim, Alex Bixel, Glenn Schneider, Ronguang Liang, Jonathan Arenberg
2019 Astronomical Journal  
An outstanding, multi-disciplinary goal of modern science is the study of the diversity of potentially Earth-like planets and the search for life in them.  ...  MODE lenses can be cost-effectively replicated through molding.  ...  Here we will briefly review three challenges that must be overcome to enable the replication of large-scale MODE lenses. First, diamond-turning and molding machines must be scaled up significantly.  ...

Advanced automation for space missions

1981 Microprocessing and Microprogramming  
(4) a self-replicating, growing lunar factory.  ...  Four candidate applications missions were considered. (1) An intelligent Earth-sensing information system, (2) an autonomous space exploration system, (3) an automated space manufacturing facility, and  ...  Control of a large-scale space manufacturing or replicating system demands a distributed, hierarchial, dynamic, machine-intelligent information system.  ...

The entropy principle, and the influence of sociological pressures on SETI

V. Bozhilov, Duncan H. Forgan
2010 International Journal of Astrobiology  
We begin with the premise that the law of entropy could prove to be fundamental for the evolution of intelligent life and the advent of technological civilization.  ...  A numerical test for a proposed significance of the law of entropy within the evolution of intelligent species is performed and results are compared with a neutral test hypothesis.  ...  Planetary systems are then generated for these stars, and life is allowed to evolve on these planets according to some hypothesis of origin.  ...

Artificial Digitality (A Musical Journey to the Future)

Kuldeep Gohel
2019 Journal of Computers  
The author uses music, mathematics, and the emerging machine learning field to create a musical story.  ...  The author's constant effort to achieve a system that can replicate his style of music production has finally led him to a neural network and a mathematical system that clones his musical passion.  ...  He considers machine learning as a tool to replicate his brain and generate a body in the computer that he can share his soul with.  ...

Percolation clusters of organics in interstellar ice grains as the incubators of life [article]

Saibal Mitra
2019 arXiv   pre-print
I show that on time scales of ≳ 10^6 years, these processes lead to the formation of large percolation clusters of organic molecules.  ...  I argue that models for abiogenesis are more likely to work when considered inside such micro-environments.  ...  Acknowledgment I thank Glennys Farrar for pointing out the source of the CRs needed in the proposed scenario.  ...

Piotr Skowron, Krzysztof Rzadca
2013 2013 International Conference on High Performance Computing & Simulation (HPCS)

A Distributed Multilevel Force-directed Algorithm [article]

Alessio Arleo, Walter Didimo, Giuseppe Liotta, Fabrizio Montecchiani
2016 arXiv   pre-print
The wide availability of powerful and inexpensive cloud computing services naturally motivates the study of distributed graph layout algorithms, able to scale to very large graphs.  ...  We present the first multilevel force-directed algorithm based on a distributed vertex-centric paradigm, and its implementation on Giraph, a popular platform for distributed graph algorithms.  ...  The state of a vertex can receive one of the following values: sun, planet, moon, or unassigned. We shall call sun, planet, moon, or unassigned, a vertex with the corresponding value for its state.  ...
