An acoustic plate-valve resonator is developed and optimized to maximize absorption by enhancing the Helmholtz resonance with coincident structural vibrations of plate-valve. The current research initially examines concept experimentally a 3D printed valve. Then use analytical numerical modeling, analysis performed, which allows eigenmodes eigenfrequencies be determined. When properties are mod...

We present a new method of fractal-based texture analysis, using the multiscale fractional Brownian motion texture model, and a new parameter, intermittency. The intermittency parameter p describes a degree of presence of the textural information: a low value of p implies a very lacunar texture. The multi-scale fractional Brownian motion model allows to construct multiregime textures in the fre...

This paper proposes a location sensing model based on passive RFID systems. The proposed model is useful for identifying the location of moving nodes relative to existing anchor nodes, i.e. nodes with known coordinates, which has applications in logistics, yard and warehouse management. The study explores algorithms for estimating location coordinates. These algorithms are much simpler to imple...

We introduce a technique that limits absorption effects in fluorescence imaging and does not require extensive imaging processing, thus allowing for video rate imaging. The absorption minimization is achieved using spatial frequency domain imaging at a single high spatial frequency with standard three-phase demodulation. At a spatial frequency f ¼ 0.5 mm−1, we demonstrated in both in-vitro phan...
