Antarctica has to be one of the most mysterious places on Earth. Just what secrets does it hold? Maybe you can figure it out…. I will go into more detail in the blog, but here is a quick run down. Buzz Aldrin, the famous astronaut who walked on the moon, went to Antarctica and had to be emergency medically evacuated out of there. Now this part is controversial. Then the tweet was erased, and that become the conspiracy theory, some claiming it was a fraud and never happened. You guys can decide on this one, but after you hear all the other weird things going on in Antarctica, you might wonder, could this possibly be true? One of the strangest stories in recent times though, with Antarctica, is with what many think is the Ark of Gabriel. First we should start with how they found it, and the crazy events that occurred when they tried to remove it. Underneath the Masjid al-Haram mosque, the holiest place in Islam, they found what looked like the legendary weapon, that is known as the Ark of Gabriel. When they tried to remove it, in September ofthere was a huge lightning, or plasma emission, that reportedly injured Mystery in Antarctica. There Mystery in Antarctica a second attempt to remove the Ark 13 days later, which resulted in a much larger plasma emission, this time killing between to people, depending on the news source.

  • Evolving Behaviour Trees for Supervisory Control of Robot Swarms
    Evolving Behaviour Trees for Supervisory Control of Robot Swarms Elliott Hogg1y, Sabine Hauert1, David Harvey, Arthur Richards1 1Bristol Robotics Laboratory, University of Bristol, UK. E-mail: [email protected], [email protected] Abstract: Supervisory control of swarms is essential to their deployment in real world scenarios to both monitor their operation and provide guidance. We explore mechanisms by which humans might provide supervisory control to swarms and improve their performance. Rather than have humans guess the correct form of supervisory control, we use artificial evolution to learn effective human-readable strategies to help human operators understanding and performance when con- trolling swarms. These strategies can be thoroughly tested and can provide knowledge to be used in the future in a variety of scenarios. Behaviour trees are applied to represent human readable decision strategies which are produced through evolution. We investigate a simulated set of scenarios where a swarm of robots have to explore varying environments and reach sets of objectives. Effective supervisory control strategies are evolved to explore each environment using different local swarm behaviours. The evolved behaviour trees are animated alongside swarm simulations to enable clear under- standing of the supervisory strategies. We conclude by identifying the strengths in accelerated testing and the benefits of this approach for scenario exploration and training of human operators.

  • The Reception and Commemoration of William Speirs Bruce Are, I Suggest, Part
    The University of Edinburgh School of Geosciences Institute of Geography A SCOT OF THE ANTARCTIC: THE RECEPTION AND COMMEMORATION OF WILLIAM SPEIRS BRUCE M.Sc. by Research in Geography Innes M. Keighren 12 September 2003 Declaration of originality I hereby declare that this dissertation has been composed by me and is based on my own work. 12 September 2003 ii Abstract 2002–2004 marks the centenary of the Scottish National Antarctic Expedition. Led by the Scots naturalist and oceanographer William Speirs Bruce (1867–1921), the Expedition, a two-year exploration of the Weddell Sea, was an exercise in scientific accumulation, rather than territorial acquisition. Distinct in its focus from that of other expeditions undertaken during the ‘Heroic Age’ of polar exploration, the Scottish National Antarctic Expedition, and Bruce in particular, were subject to a distinct press interpretation. From an examination of contemporary newspaper reports, this thesis traces the popular reception of Bruce—revealing how geographies of reporting and of reading engendered locally particular understandings of him. Inspired, too, by recent work in the history of science outlining the constitutive significance of place, this study considers the influence of certain important spaces—venues of collection, analysis, and display—on the conception, communication, and reception of Bruce’s polar knowledge. Finally, from the perspective afforded by the centenary of his Scottish National Antarctic Expedition, this paper illustrates how space and place have conspired, also, to direct Bruce’s ‘commemorative trajectory’—to define the ways in which, and by whom, Bruce has been remembered since his death. iii Acknowledgements For their advice, assistance, and encouragement during the research and writing of this thesis I should like to thank Michael Bolik (University of Dundee); Margaret Deacon (Southampton Oceanography Centre); Graham Durant (Hunterian Museum); Narve Fulsås (University of Tromsø); Stanley K.

Swarm Intelligence relies upon stigmergic principles in order to solve complex problems using only simple agents. Swarm Intelligence has been receiving increasing attention over the last 10 years as a result of the acknowledgement of the success of social insect systems in solving complex problems without the need for central control or global information. In swarm- based problem solving, a solution emerges as a result of the collective action of the members of the swarm, often using principles of communication known as stigmergy. The individual behaviours of swarm members do not indicate the nature of the emergent collective behaviour and the solution process is generally very robust to the loss of individual swarm members. This report describes the general principles for swarm-based problem solving, the way in which stigmergy is employed, and presents a number of high level algorithms that have proven utility in solving hard optimization and control problems. Useful tools for the modelling and investigation of swarm-based systems are then briefly described.

  • Swarm Intelligence Among Humans the Case of Alcoholics
    Swarm Intelligence among Humans The Case of Alcoholics Andrew Schumann1 and Vadim Fris2 1Department of Cognitivistics, University of Information Technology and Management in Rzeszow, Sucharskiego 2, 35-225, Rzeszow, Poland 2Private Health Unitary Enterprise “Iscelenie”, Kazinca 120, 220000 Minsk, Belarus Keywords: Swarm Intelligence, Swarm Computing, Alcoholic, Illocutionary. Abstract: There are many forms of swarm behaviour, such as swarming of insects, flocking of birds, herding of quadrupeds, and schooling of fish. Sometimes people behave unconsciously and this behaviour of them has the same patterns as behaviour of swarms. For instance, pedestrians behave as herding or flocking, aircraft boarding passengers behave as ant colony, people in escape panic behave as flocking, etc. In this paper we propose a swarm model of people with an addictive behaviour. In particular, we consider small groups of alcohol-dependent people drinking together as swarms with a form of intelligence. In order to formalize this intelligence, we appeal to modal logics K and its modification K'. The logic K is used to formalize preference relation in the case of lateral inhibition in distributing people to drink jointly and the logic K' is used to formalize preference relation in the case of lateral activation in distributing people to drink jointly. 1 INTRODUCTION mammals, too, e.g. among naked mole-rats (Heterocephalus glaber sp.).

  • Science & Fiction-Febr, 2020 1 Off-Shore Fly Or Die
    Science & Fiction-Febr, 2020 Off-Shore Fly or Die Holograms for Desert Locust Swarms Dr. Ugur Sevilmis Eastern Mediterranean Agricultural Research Institute, Adana, Turkey [email protected] Abstract A random walk search was conducted on academic papers to find a method for ecological combat of desert locust. Relatedness of papers and concepts were mainly analysed with the core idea of “Fighting Rooster” vs “Desert Locust “ interspecies competition. It was interesting to find a better preator than fighting roosters for locust swarms in the sea. Usage of a technology is required in this theoric approach to modify collective behavior of desert locusts which looks like the achilles heel of swarms. Keywords: Invasion, migration, predation, interspecies competition, süper-organism, swarm intelligence, collective intelligence, multi-species communities Conclusions A locust swarm is a highly adaptive süper-organism using collective behavior and collective intelligence. Complex interactions exists within its interiror and environmental relations coming from genetic evolution of this species. It is hard to totally change its capacity of foraging on herbage due to its high adaptation capacity. The best method to prevent it is to keep them away from terestial ecosystems and keep them off-shore to spend their fats. Just one day will be adequate to destroy a whole swarm; when the night comes. During night time when all individual visual sensors are shut down, the süper-organsim will be fragmented. Under dark and no landing condition, they will spend their energy. Dead bodies of locusts will be the landing zone for the rest of the huge swarm. But predator fishes will be vey happy to hunt 40 and 80 million locusts per square kilometer (a total of around 50 to 100 billion locusts per swarm, representing 100,000 to 200,000 tons of flesh).

  • An Equation of State for Insect Swarms Michael Sinhuber1,3,4, Kasper Van Der Vaart1,4, Yenchia Feng1, Andrew M
    www.nature.com/scientificreports OPEN An equation of state for insect swarms Michael Sinhuber1,3,4, Kasper van der Vaart1,4, Yenchia Feng1, Andrew M. Reynolds2 & Nicholas T. Ouellette1* Collective behaviour in focks, crowds, and swarms occurs throughout the biological world. Animal groups are generally assumed to be evolutionarily adapted to robustly achieve particular functions, so there is widespread interest in exploiting collective behaviour for bio-inspired engineering. However, this requires understanding the precise properties and function of groups, which remains a challenge. Here, we demonstrate that collective groups can be described in a thermodynamic framework. We defne an appropriate set of state variables and extract an equation of state for laboratory midge swarms. We then drive swarms through “thermodynamic” cycles via external stimuli, and show that our equation of state holds throughout. Our fndings demonstrate a new way of precisely quantifying the nature of collective groups and provide a cornerstone for potential future engineering design. Organisms on every size scale, from single-celled1 to highly complex2, regularly come together in groups. In many cases, such aggregations are collective, in that the group as a whole displays properties and functionality distinct from those of its individual members or simply their linear sum3,4. It is generally assumed that since evolution has led so many diferent kinds of animals to behave collectively, the performance of collective groups at whatever task they seek to achieve ought to be well beyond the capabilities of a single individual5, while also being robust to uncertain natural environments 6,7 and operating without the need for top-down control 8.
