The physical mechanism of aerial dispersal of spiders, “ballooning behavior,” is still unclear because of the lack of serious scientific observations and experiments. Therefore, as a first step in clarifying the phenomenon, we studied the ballooning behavior of relatively large spiders (heavier than 5 mg) in nature. Additional wind tunnel tests to identify ballooning silks were implemented in the laboratory. From our observation, it seems obvious that spiders actively evaluate the condition of the ...

Experiments were performed on a flat-plate airfoil and an Eppler E338 airfoil at very low flight Reynolds numbers (3000 ≤ Re ≤ 50,000), in which dielectric barrier discharge plasma actuators were employed at the airfoil leading edges to effect flow control. The actuators were driven in a high-frequency (kilohertz) steady mode and a pulsed mode in which pulse frequency and duty cycle were varied in a systematic fashion. Optimum reduced frequencies for generating poststall lift were approximately between ...

14 examples prove the potency of the evolution strategy. The exemplary compilation starts with the drag-minimization of a wing-like construction in a wind tunnel and ends with the creation of an extraordinary magic square on a computer. Prerequisite for a successful evolutionary optimization is the validity of strong (or at least piecemeal strong) causality for the quality function. The problem solution fails without any inherent order of the quality function. Euler's extension of Fermat's last theorem ...

Biological Evolution has done development work on animated matter for more than three billion years. The method used in this process is the equivalent of an astute optimization procedure which is proverable by the theory of Evolution Strategy.

Preston's method of measuring skin friction, which makes use of a Pitot tube resting on the surface, depends upon the assumption of a region of flow similarity, adjacent to the wall, common to fully developed turbulent pipe flow and the turbulent boundary layer. Experiments performed elsewhere have cast considerable doubt on the validity of this assumption, and the present investigation was undertaken to establish whether or not it is justified. Experiments were carried out in a short length of ...

A desert-living spider sparassid (Cebrennus rechenbergi Jäger, 2014) and several lycosid spiders (Evippomma rechenbergi Bayer, Foelix & Alderweireldt 2017, Allocosa senex (Mello-Leitão, 1945), Geolycosa missouriensis (Banks, 1895)) were studied with respect to their burrow construction. These spiders face the problem of how to transport dry sand and how to achieve a stable vertical tube. Cebrunnus rechenbergi and A. senex have long bristles on their palps and chelicerae which form a carrying basket (psammophore). ...

A key challenge in electrical discharge machining (EDM) is to find a suitable combination out of numerous process parameters. Any changes concerning the electrode materials or geometries require newly optimized technologies. These technologies are to be developed from a considerable number of experiments which must be carried out by an experienced operator. This paper presents a new method of finding the optimal set of parameters. Here, the performance of the evolution strategy (ES), a stochastic, ...

Spiders utilize their fine silk fibers for their aerial dispersal, known as ballooning. With this method, spiders can disperse hundreds of kilometers, reaching as high as 4.5 km. However, the passive dynamics of a ballooning model (a highly flexible filament and a spider body at the end of it) are not well understood. Here, we introduce a bead–spring model that takes into account the anisotropic drag of a fiber to investigate the passive dynamics by the various non-uniform flows: (i) a shear flow, ( ...

Passive flight in living things, such as in maple or dandelion seeds, is one of the most primitive methods of aerial dispersal. This mechanism is robust and efficient, as it utilizes the present wind conditions. Passive flight is used not only by plant seeds but also by some animals. Spiders use fine, flexible silk filaments to fly, a behavior known as ballooning. This capability is distinct from that of other winged insects, as some ballooning spiders can travel hundreds of kilometers, reaching ...
