Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …

Validation of a new method for ultrasonic structural health monitoring using advanced signal analysis. This paper presents the results of research on a new method for the monitoring of structural health using ultrasound. Conventional ultrasonic methods use the damping of the first arrival of the echo …

This article discusses the revival of the interferometric positioning experiment with GPS signals that aims at measuring the three-dimensional vector between two stations. Such an experiment was carried out in the late seventies, the early days of the GPS system, almost simultaneously by two competing …

Software-Defined Receivers (SDR) are radio receivers that contain as few hardware components as possible. In such a receiver, the signal processing block then starts as close as possible after the antenna, and is carried out with scripts running on a general-purpose processor contrary to traditional …

The exploitation of the metagenome for novel biocatalysts by functional screening is determined by the ability to express the respective genes in a surrogate host. The probability of recovering a certain gene thereby depends on its abundance in the environmental DNA used for library construction, the …

The author re-examines the the Bosnian-Serb attack on Srebrenica. His analysis focusses on the initial stage before the fall of the enclave. He tries to introduce a different perspective on the way key decision-makers of UNPROFOR in Srebrenica (Karremans), Sarajevo (Smith, Nicolai) and Zagreb (Janvier), …
