One of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. As a result, the tool would be worn and its life time would be reduced. Therefore, in long time machining, it is essential to change inserts and tools, continiously. A milling tool with self rotary cutting inserts was designed and manufactured that enables i...

Starting from a minimal physical model of self-propelled hard rods on a substrate in two dimensions, we derive a modified Smoluchowski equation for the system. Self-propulsion enhances longitudinal diffusion and modifies the mean-field excluded volume interaction. From the Smoluchowski equation we obtain hydrodynamic equations for rod concentration, polarization and nematic order parameter. New...

Denote by C the elliptic curve y = x(x − 1)(x− s) over the function field Q(s). It degenerates only over the points s = 0, 1,∞ of P and so defines a fiber bundle over C \ {0, 1} with fibers being elliptic curves. Let Fs denote the fiber over the point s. The maps ι : (x, y, s) 7→ (1 − x, iy, 1 − s) and τ : (x, y, s) 7→ (x̄, ȳ, s̄) are topological automorphisms of C. Note ι = −1, τ = 1. The fundam...

The goal of this article is to examine the effectiveness of “forloop” and “while-loop” statements on SCMPDS by insert sort. In this article, first of all, we present an approach to compute the execution result of “for-loop” program by “loop-invariant”, based on Hoare’s axioms for program verification. Secondly, we extend the fundamental properties of the finite sequence and complex instructions...

Self-propelled particles can exhibit surprising non-equilibrium behaviors, and how they interact with obstacles or boundaries remains an important open problem. Here we show that chemically propelled micro-rods can be captured, with little change in their speed, into close orbits around solid spheres resting on or near a horizontal plane. We show that this interaction between sphere and particl...

Fluid convection and mixing induced by bubble-propelled tubular microengines are characterized using passive microsphere tracers. Enhanced transport of the passive tracers by bubble-propelled micromotors, indicated by their mean squared displacement (MSD), is dramatically larger than that observed in the presence of catalytic nanowires and Janus particle motors. Bubble generation is shown to pl...

Efficient swimming of biologically carangiform robotic fish has been investigated by using a novel experimental method. The laboratory robotic fish model, which follows an exact replica of Saithe, is self-propelled on a servo towing system. The forward towing speed is determined by the fluid force acting on the robotic fish, as the fish undulates its body in the water. The importance of the sel...
