Osteoporosis is defined by a decrease in bone mass and a deterioration in bone microstructure. It is a major public health issue and a significant economic burden for both individuals and society. Thus, monitoring bone mass and structure is necessary to p... see more

This work presents the implementation of a hardware and software package used to conduct a physical experiment via the web to create remotely a practical work laboratory. For this reason, we chose to put online a model of experiment concerning the backsca... see more

In this study we investigated depth distributions of elements in the multilayer structures of TiO2_2/SiO2_2/Si before and after ion irradiation. The samples were implanted with Ne+^+, Ar+^+, Kr+^+ and Xe+^+ ions. For each implantation the multilayer struc... see more

This paper presents the results of an experimental study of three samples containing various elements in the near-surface layers. The depth profiles of all the elements of different atomic masses from hydrogen to silver were investigated by... see more

The three dimensional internal structure and distribution of trace elements of zircon are clarified from the observation of backscattered electron and cathodoluminescence images of zircon plus electron microprobe quantitative determinations of U, Y and Hf... see more

The present studies aimed to investigate the effects of energy dependence of parameters characterizing multiply backscattering of gamma photons. The numbers of multiply backscattered events are found to be increasing with thickness of copper target, and s... see more

Backscatter mosaics based on a multi-frequency multibeam echosounder survey in the continental shelf setting of the North Sea were compared. The uncalibrated backscatter data were recorded with frequencies of 200, 400 and 600 kHz. The results showed that ... see more

Three experiments were conducted in the Belgian part of the North Sea to investigate short-term variation in seafloor backscatter strength (BS) obtained with multibeam echosounders (MBES). Measurements were acquired on predominantly gravelly (offshore) an... see more

This work studies the performance of two methods for providing power to an ultra-low power, ambient backscatter tag, omitting the need for any battery. RF energy harvesting from a dedicated source and energy harvesting from ambient light using a single ph... see more
