3D reconstruction based on laser light projection is a well-known method that generally provides accurate results. However, when this method is used for inspection in uncontrolled environments, it is greatly affected by vibrations. This paper presents a structured-light sensor based on two laser stripes that provides a 3D reconstruction without vibrations. Using more than one laser stripe provi...

CVETANOVIC, B. and D. ZLATKOVIC, 2013. Evaluation of whole-body vibration risk in agricultural tractor drivers. Bulg. J. Agric. Sci., 19: 1155-1160 During their work, agricultural tractor drivers are exposed to various negative influences, among which vibrations are especially harmful. It is about vibrations generated in engine while the tractor is working, which are then transmitted to the dri...

Vibration tests are commonly used to design or qualify products such as electronics, auto parts, and consumer goods, and ensure they can withstand transportation and normal use or occasional vibration shocks. Many vibration tests specify random, sine, or classic shock vibration profiles. These produce vibrations from mathematically parameterized models and result in very predictive and consiste...

The motorcycle riders are subjected to extreme vibrations due to the vibrations of its engine, improper structural design of the motorcycle and the bad road conditions. The literature review reveals that the vibrations are most hazardous to the health if it exceeds the limit. The experiments were conducted to measure the magnitude of the vibrations acting on the rider during motorcycle riding u...

Mechanical vibrations of different products generate usually noise and additionally tactile information. In most cases, these auditory and tactile information are non-stationary signals. In the present study, a pilot psychophysical experiment was conducted to investigate the influence of non-stationary vibrations on the quality of non-stationary product sounds. In this experiment, non-stationar...

Jednym z państw-sygnatariuszy Europejskiej Karty Samorządu Lokalnego jest Republika Malty, w której samorząd terytorialny wprowadzono na mocy ustawy dnia 30 czerwca 1993 roku o radach lokalnych. W raporcie pokontrolnym Komitetu Monitorującego podniesiono, że maltański narusza postanowienia Karty, ponieważ jednostki samorządowe nie są pełni niezależne finansowo. Komitet postulował także przekaza...

When sliding our fingertip against a textured surface, complex vibrations are produced in the skin. It is increasingly recognised that the neural transduction and processing of these vibrations plays an important role in the dynamic tactile perception of textures. The aim of the present study was to develop a novel means to tag the cortical activity related to the processing of these vibrations...

Thickness-shear vibrations of a plate is one of the most widely used functioning modes of quartz crystal resonators. For an analysis of vibrations, the Mindlin and Lee plate theories based on the displacement expansion of the thickness coordinate have been used as the linear theories. However, due to lacking of available method and complexity of the problem, the nonlinear thickness-shear vibrat...

Asymptotic behaviour of eigenvalues and eigenfunctions of a stiff problem is described in the case of the fourth-order ordinary differential operator. Considering the stiffness coefficient that depends on a small parameter ε and vanishes as ε → 0 on a subinterval, we prove the existence of low and high frequency resonance vibrations. The low frequency vibrations admit the power series expansion...
