Operational Analysis Of Improved Γ-Z-Source Inverter With Clamping Diode And Its Comparative Evaluation, Zeeshan Aleem, Moin Hanif Jan 2017

Operational Analysis Of Improved Γ-Z-Source Inverter With Clamping Diode And Its Comparative Evaluation, Zeeshan Aleem, Moin Hanif

Articles

Due to a substantial shortage of conventional energy sources, the utilization of renewable energy is gaining attention. Power converters form interfaces to provide power from renewable energy sources to end user systems. Impedance-source inverters (ZSIs) have become a research hotspot and are widely used to overcome the drawbacks of conventional voltage-source inverters and current-source inverters such as two-stage power conversion and less immunity to electromagnetic interference noises. This paper presents various transformer-based ZSIs mainly classified as trans-ZSIs, improved trans-ZSIs, inductor-capacitor-capacitor transformer ZSI, TZSIs, and their comparisons with a new family of ZSIs called Γ-Z-source inverters (ΓZSI). Full operational analysis of …


A Fast Linear Electro-Optical Effect In A Non-Chiral Bent-Core Liquid Crystal, Yuri Panarin, S.P. Sreenilayam, J.K. Vij, A. Lehmann, C. Tschierske Jan 2017

A Fast Linear Electro-Optical Effect In A Non-Chiral Bent-Core Liquid Crystal, Yuri Panarin, S.P. Sreenilayam, J.K. Vij, A. Lehmann, C. Tschierske

Articles

We report the observation of an electro-optical effect for a linear rotation of the optical axis as function of the electric field in an achiral tilted bent-core liquid crystalline compound, in which 4-cyanoresorcinol bisbenzoate core is symmetrically terminated by long linear alkyl chains (n =16) on both ends. The linear electro-optic effect observed in this material is similar to the deformed helical ferroelectric liquid crystal (DHFLC) effect reported previously in a FLC material except that dimensions of the helical pitch differ by two orders of magnitude. In the chiral systems, the helical pitch usually lies on the scale of sub-optical …


The Application Of Digital Accelerometers For Wired And Non-Wired Mechanomyography, Niall Campbell, Thomas Egan, Catherine Deegan Jan 2017

The Application Of Digital Accelerometers For Wired And Non-Wired Mechanomyography, Niall Campbell, Thomas Egan, Catherine Deegan

Conference papers

The objective of this paper is to consider the use of digital accelerometers for Mechanomyographic applications. The digital outputs of the accelerometer require the consideration of additional interfacing hardware for any commercial data acquisition systems being considered. The Arduino open-source platform is shown to meet this requirement. This platform also provides access to set the data registers on the accelerometer to output data at the resolution, speed and format required. Results show that digital accelerometers provide an accurate representation of the MMG signal. The second objective of this work was to extend this digital platform to design a wireless MMG …
