This paper is devoted to the current status of novel fully active 3D (three-dimensional) fine-grained scintillator detector SuperFGD as a main part near off-axis upgrade program for T2K experiment. The following important components related such electronics and mechanics, wavelength shifting (WLS) fibers, light emitting diode (LED) calibration system are also discussed here well detector’s futu...

We have designed a novel working strategy to optimize a unique chromatographic method consisting of diode array detection for the analysis of the most representative phenolic compounds from different food sources. The simultaneous inclusion of standard phenolic compounds, phenolic compounds isolated from food sources and representative real extracts as an ultimate test in analysis has allowed t...

This paper describes a neutron monitor which consists of a spherical neutron moderator, 12′′ in diameter, with a thermal neutron detector which detects delayed β-radiation from silver activation. The thermal neutron detector is based on four silicon diodes at the centre of the moderator, two of which are covered by silver foils, 250 μm thick, and two by tin foils, 360 μm thick. The latter two d...

In this thesis some multivariate spectroscopic methods for the analysis of solutions are proposed. Spectroscopy and multivariate data analysis form a powerful combination for obtaining both quantitative and qualitative information and it is shown how spectroscopic techniques in combination with chemometric data evaluation can be used to obtain rapid, simple and efficient analytical methods. The...

Magnetic field sensors based on organic thin-film materials have attracted considerable interest in recent years as they can be manufactured at very low cost and on flexible substrates. However, the technological relevance of such magnetoresistive sensors is limited owing to their narrow magnetic field ranges (∼30 mT) and the continuous calibration required to compensate temperature fluctuation...

1 Two New Six-Port Re ectometers Covering Very Large Bandwidths Jan Hesselbarth, Frank Wiedmann, and Bernard Huyart, Member, IEEE Abstract|This paper presents two new structures for sixport re ectometers with very large operating bandwidths of more than three decades, using a combination of lumped re ectors and transmission lines. Circuits working over a range of 2 MHz to 1 300 MHz and 2 MHz to...

Caffeine is a natural substance present in leaves and seeds of many plants. The aim of this study is to evaluate the caffeine level in the carbonated drinks from the Romanian market. For this survey were taken 30 samples of different carbonated drinks. The caffeine was determined and quantified using a HPLC with diode array detector at 206 nm. The caffeine retention time was at 17.785 minutes. ...

This work presents an energy-efficient diode-based CMOS temperature sensor. It is based on the capacitively-biased diode (CBD) working principle and can operate with a 1-V supply voltage. Instead of using separate CBD front-end ADC, new architecture proposed in which directly embedded into 1st stage 1-bit 2nd-order switched-capacitor Σ-ADC, thereby improving both energy efficiency accuracy. The...
