We present experimental Lagrangian statistics of finite sized, neutrally bouyant, particles transported in an isotropic turbulent flow. The particle's diameter is varied over turbulent inertial scales. Finite size effects are shown not to be trivially related to velocity intermittency. The global shape of the particle's acceleration probability density functions is not found to depend significa...

A Digital Microfluidic Biochip (DMFB) offers a promising platform for medical diagnostics, DNA sequencing, Polymerase Chain Reaction (PCR), and drug discovery and development. Conventional Drug discovery procedures require timely and costly manned experiments with a high degree of human errors with no guarantee of success. On the other hand, DMFB can be a great solution for miniaturization, int...

e-mail: [email protected] Abstract. We computed the energy spectra of the incident (on an air shower array) ultrahighenergy (E > 4⋅10 eV) cosmic rays (CRs) that were accelerated in nearby Seyfert nuclei at redshifts z≤ 0.0092 and in BL Lac objects. These were identified as possible CR sources in our previous works. For our calculations, we took the distribution of these sources over the sky...

In this study, a method for detecting the railway surface defects called “squats” using ABA (Axle Box Acceleration) measurement of trains was proposed. prototype design, implementation, and field tests were conducted to derive verify results. The test performed proven precision system, measured data signal-processed Matlab program. algorithm used determine position squats developed based on wav...

Automated design tools help to capture the benefits of customization in embedded system design while not exceeding design budgets. Such design tools must understand and exploit the hierarchical structure of design spaces, because systems of any significant complexity typically consist of components (subsystems). In order to reduce the design cost for such systems, designers develop the best com...

Electron acceleration mechanism at high Mach number collisionless shocks propagating in a weakly magnetized medium is investigated by a self-consistent two-dimensional particle-in-cell simulation. Simulation results show that strong electrostatic waves are excited via the electron-ion electrostatic two-stream instability at the leading edge of the shock transition region as in the case of earli...

A way of describing lateral acceleration for fatigue assessments is discussed. The purpose of the model is to parameterise the different sources of the fatigue load, such as the operating environment and the influence of the driver. The measured lateral acceleration is modelled with an approximative curvature, and the average speed explaining centripetal acceleration in the curve. The differenc...

The paper presents an application of digital filtering in data processing of acceleration records from earthquakes. Butterworth, Chebyshev, and Bessel filters with different orders are considered to eliminate the frequency noise. A dataset under investigation includes accelerograms from three stations, located in Turkey (Dinar, Izmit, Kusadasi), all working with an analogue type of seismograph ...
