This paper proposes a method for phase difference measurement based on the principle of progressive phase shift (PPS). A phase difference measurement system based on PPS and implemented in the FPGA chip is proposed and tested. In the realized system, a fu... see more

Electromagnetic (EM) simulation of dual-polarized antennas is necessary for precise initial alignments, calibration and performance predictions of multi-function phased array radar systems. To achieve the required flexibility and scalability, a novel Fini... see more

When the receivers of GPS, GLONASS, COMPASS and other such systems are equipped with multiple antennas, they can give attitude information. Based on the difference carrier phase equations established in local level frame (LLF), a new algorithm is presente... see more

A new method of measuring of the phase difference of electromagnetic signals by a photopolarimetric method is offered in this work. The advantage of an offered method before the known ones of phase measuring is shown. The potential error of method is abou... see more

Rayleigh wave detection is a recently developed method for shallow seismic exploration. Current Rayleigh wave data processing and interpretation methods can only provide the transverse average wave velocity of rock-soil bodies under the geophone array ran... see more

Many different high-precision systems for determining the ratio error and phase displacement of current transformers have been developed by leading specialists in the world. The latest research solutions with the use of the latest measurement tools, insta... see more

This research attempted to measure chicken intramuscular fat content using improved ultrasound B-mode images and image segmentation. Adapted B-mode imaging is proposed to increase the positioning accuracy of B-mode images with the objective to correct the... see more

Double-differenced GPS carrier phase measurements are commonly used in GPS precise positioning applications and processed with algorithms based on the least-squares (LS) principle. In order to apply the LS principle, one needs to define properly both the ... see more

Nausea and vomiting may occur in patients receiving chemotherapy, a condition referred to as chemotherapy-induced nausea and vomiting. The provision of combined dexamethasone and ondansetron or granisetron is the therapeutic management of acute phase naus... see more
