DEPENDENCE OF ELECTROSTATIC POTENTIAL ON THE TRANSPORTATION SPEED DURING AIR CHARGING

The wide use of pneumatic method of loading and portage of granular explosives (ВВ) at the conduct of mountain works specifies on the necessity of researches of defects concomitant to this method: namely an origin of electrification in a charge hose. Electric potential and charge are the basic parameters of the energy distinguished at a digit, the amount of warmth of thatgoes to the warming-up of VV. In the total, knowing the minimum temperatures of selfignition of a erodredges, it is possible to control the size ofelectric charge and exceeding of that conduces to the unplanned explosion.

Effect of the chute oscillations frequency on the speed of inertial-conveyor transportation of concrete mix

The paper represents the major advantages of use of the author’s technology of concrete mix feeding to the point of placement in a building site environment. The working procedure of the experimental research of the effect of frequency work regimes of involved in this case inertia conveyors with the working body in the form of a chute on the transportation speed of ready-mix concrete on the dense aggregate is described and proved. The results of this research are given, particularly, it is shown how an optimal frequency of chute oscillations depends on the angle of its slope and technological properties of transported mix.

Dilation of Time Dilation

The study addresses the issue of the so-called time dilation in the sense of the origin of its creation and the physical existence.Based on the work of Lorentz, who the lack of displacement of interference fringes in the Michelson interferometer explained wrongly with, shortening one arm of the interferometer, I propose the construction of the light pulse clock, in which to measure the rate of the passage of time is used constancy speed of light in vacuum.Light clock, the construction of which is described in the paper, stationary in relation to the ether, will measure constant time intervals. The same clock transported, will slow down the pace of his walk as a function of transportation speed v and that is a novelty, will slow depending on its orientation relative to the direction of motion. Light clock transported transversely with respect to the stationary clock will slow gamma times, transported lengthwise will slow gamma to the second power.Basing on the obtained dependences I maintain that time dilation defined in the theory of relativity (SR) as the slowing of the lapse of time, does not physically exist and identification the varying pace of walk clock with the pace of lapse of time I consider a fundamental error resulting from the postulates of this theory.

Behavioral diversity assisting obstacle navigation during group transportation in ant

Cooperative transportation behavior in ants has attracted attention from a wide range of researchers, from behavioral biologists to roboticists. Ants can accomplish complex tasks as a group whereas individual ants are not intelligent (in the context of thisstudy’s tasks). In this study, group transportation and obstacle navigation in Formica japonica, an ant species exhibiting ‘uncoordinated transportation’ (primitive group transportation), are observed using two differently conditioned colonies. Analysesfocus on the effect of group size on two key quantities: transportation speed and obstacle navigation period. Additionally, this study examines how these relationships differ between colonies. The tendencies in transportation speed differ between colonies whereas the obstacle navigation period is consistently reduced irrespective of the colony. To explain this seemingly inconsistent result in transportation speed, we focus on behavioral diversity in ‘directivity’, defined as the tendency of individual ants totransport a food item toward their own preferential direction. Directivity is not always toward the nest, but rather is distributed around it. The diversity of the first colony is less than that of the second colony. Based on the above results, a mechanical model is constructed. Using the translational and rotational motion equations of a rigid rod, the model mimics a food item being pulled by single or multiple ants. The directions of pulling forces exerted by individual ants are assumed to be distributed around the direction pointing toward the nest. The simulation results suggest that, as diversity in directivity increases, so does the success rate in more complicated obstacle navigation. In contrast, depending on group size, the speed of group transportation increases in the case of lower diversity while it is almost constant in the case of higher diversity. Transportation speed and obstacle navigation success rate are in a trade-off relationship.

Discussion on the Transportation Speed of the Horizontally Vibrating Conveyor

The vibration of the horizontally vibrating conveyor (HVC) is excited by a vibration generator with four shafts which have eccentric quality. HVC makes the lump material to go forward by friction between the materiel and conveying trough. In this paper, a method based on the discreteness of time is adopted, and the influences factors of the transportation speed of HVC are discussed.
