Comparison of Two Alternative Silicon-On-Glass Microfabrication Processes for MEMS Inertial Sensors
Torunbalci, M. M.; Tatar, E.; Alper, S. E.; Akın, Tayfun (2011-09-07)
This paper presents experimental comparison of a modified silicon-on-glass (M-SOG) process to a previously-reported classical SOG (C-SOG) process based on the use of SOI wafers, yielding a stress free < 111 > silicon structural layer with desired structure thickness. The basic difference between these processes is the sequence of the step at which the silicon microstructures are defined by DRIE, making M-SOG more robust against critical dimension (CD) variations. Overall, M-SOG provides a simple, high yield...

Fruit juice industry waste utilization includes several options that one of them extraction of bioactive compounds exhibiting antioxidant effect. In this study, ultrasound assisted extraction was applied to dried apple, sour cherry and grape pomaces by using ethanol, 50% aqueous ethanol and water solvents. For antioxidant capacity estimation of the extracts, DPPH•, ABTS•+, CUPRAC and FRAP assays were applied. The highest total phenolic contents were obtained for sour cherry and grape pomace 50% aqueous eth...
Comparison of Two Methods for Purification of Enterocin B, a Bacteriocin Produced by Enterococcus faecium W3
Dundar, Halil; ATAKAY, MEHMET; Celikbicak, Omuer; SALİH, BEKİR; Bozoglu, Faruk (Informa UK Limited, 2015-11-17)
This study aimed to compare two different approaches for the purification of enterocin B from Enterococcus faecium strain W3 based on the observation that the bacteriocin was found both in cell associated form and in culture supernatant. The first approach employed ammonium sulfate precipitation, cation-exchange chromatography, and sequential reverse-phase high-performance liquid chromatography. The latter approach exploited a pH-mediated cell adsorption-desorption method to extract cell-bound bacteriocin, ...
Comparison of partial directed coherence and dynamic bayesian network approach for brain effective connectivity modeling using fMRI
Öğe, Oğuzhan Can; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2019)
Two of the approaches attempting to model brain effective connectivity are compared. These methods are Partial Directed Coherence (PDC) and Dynamic Bayesian Network (DBN). PDC is based on linear and deterministic signal modelling. It is derived from the Granger Causality approach and underpinned by the Multivariate Auto Regressive (MVAR) model. On the other hand, DBN is based on probabilistic signal modelling, which gives DBN the ability of detecting nonlinear interactions between signals unlike all the oth...
Comparison of Two-Level and Three-Level NPC Inverter Topologies for a PMSM Drive for Electric Vehicle Applications
Madan, Alican; Bostancı, Emine (2019-01-01)
Multidimensional comparison of two-level and three-level DC/AC converters for a 120 kW permanent magnet synchronous machine (PMSM) drive is carried out in this study. Comparison of two topologies with Sinusoidal Pulse Width Modulation (SPWM) and Space Vector Pulse Width Modulation (SVPWM) by means of output current THD, conduction and switching losses, thermal stresses on semiconductors and switching frequency limitation are investigated at various operating points. Electro-thermal simulation of both topolo...
