This paper studies the way humans perceive vibrations induced by a running vehicle, starting from Stevens’ Power Law. The measurable physical magnitude was the acceleration transmitted to the hand-arm system. The ...

The acoustical parameters, dimensional determination and construction of sonic generator is described in the paper. The generator’s dimensional determination and construction show that the nozzle slot, the axial resonator ...

The importance of ultrasound frequency radiated by the sonic generator in the evolution of water quality parameters and its variation according to the pressure level of input air are described in the paper. Also, ...

The cycle of operation of hydraulic excavators has a series of steps in which large masses are accelerated and then braked. The presence of additional masses on the excavators improves stability but reduces energy efficiency. ...

The paper presents a study on the impact of chemical pollution of the soil, from residual bauxite lake, from "Mineri", in the areal of Tulcea. Soil samples were taken from the lake, and from the immediate area of the ...

The experimental research was made on superficial layers laid-down through electrical sparking on the steel carbon OLC 45 probes, the used electrode being made from a corrosion resistant material (Copper). The probes ...

Worldwide, the series of attacks "with bomb" are the most common, accounting for over 80% of terrorist attacks. The many constructive solutions of Improvised Explosive Devices (I.E.D), would require for defusing sequence ...

In the consumer’s theory, a crucial problem is to determine the substitution effect and the revenue effect in the case of one good price’s modifing. There exists two theories due to John Richard Hicks and Eugen Slutsky ...

In this study, we used a comparative research on the selected countries in setting the local market to identify solutions for Market Regulation Subsystem. We initially identified the system of market regulating and ...
