Most of the sample holders currently used in macromolecular crystallography offer limited storage density and poor initial crystal-positioning precision upon mounting on a goniometer. This has now become a limiting factor at high-throughput beamlines, where data collection can be performed in a matter of seconds. Furthermore, this lack of precision limits the potential benefits emerging from au...

The voltage source used for testing electrical equipment has to achieve special requirements, which are noted in the international standards. Still today the test voltages for routineand type tests of utilities for the power engineering are generated by motor-generator sets. Attempting to replace the m.-g. sets with static frequency converters, two major problems occur in implementing this tech...

One of the main objectives of the smart grid initiative is to enable bulk power transmission over long distance, with reduced transmission losses. Besides the traditional high-voltage alternating current (HVAC) transmission, with the advancement in power electronics, high-voltage direct current (HVDC) transmission is increasingly becoming important. One of the main factors impacting the transmi...

A simple circuit technique to realize differential voltage-to-frequency converter suitable for telemetry is presented. The realization method employs second-generation current conveyors in connection with Set-Reset latch to generate the oscillating output signal whose frequency is proportional to the difference between two input voltages. The converter gain can be easily adjusted through the va...

Nuclear reactors are an essential source of neutrinos. In this proceeding, I review the past and current status research on neutrino oscillations using reactor also present a promising idea for positron tagging that will potentially be game-changer in field.

In order to compare the impact of passive (like network restructuring) or active (like on-load-tap-changer) grid management measures a novel tool was developed, which performs specific load flow benchmarks tests using synthetic daily load and infeed profiles. In this paper first preliminary results of the analysis of a real urban medium voltage distribution grid with 122 substations using this ...

Bitcoin, the latest Internet phenomenon branded as a game-changer. It is a revolution in financial system and money creation mechanics which currently holds the market of almost 13 billion USD. At the same time, its inner working is presented as hard to understand but perfectly trustworthy and safe. This trust is what gives Bitcoin value, however due to its mystical creator and recent headlines...

The most common cause of power transformer failures is mechanical defect brought about by excessive vibration, which is formed by the combination of multiples of a frequency of 120 Hz. In this paper, the types of mechanical exciting forces applied to the power transformer were classified, and the mechanical damage mechanism of the power transformer was identified using the vibration transfer ro...

Since the inception of dental hygiene in 1913, we have witnessed the tremendous evolution of the profession. Within the past couple two decades a significant game changer has been technology. The ability to expand access to education through technology has resulted in an increasing number of dental hygienists seeking advanced degrees and gaining new skills and certifications. The evidence shows...

Modern frequency power converters generate a wide spectrum of harmonic components. Large converter systems can also generate noncharacteristic harmonics and interharmonics. Standard tools of harmonic analysis based on the Fourier transform assume that only harmonics are present and the periodicity intervals are fixed, while periodicity intervals in the presence of interharmonics are variable an...
