Quartz bleaching by oxalic acid: Relationship between rejection rate of impurities and color response
(Baski, 2019)
Quartz beneficiation has been applied to meet market requirements by physical and/or chemical methods. Chemical beneficiation has long been investigated by inorganic (e.g. sulfuric acid) and organic (e.g. oxalic acid) ...
Broadband UHF directional coupler with high directivity
(Institute of Electrical and Electronics Engineers Inc., 2019)
A novel microstrip directional coupler operating at UHF band from 1 to 3 GHz is presented. The coupler was designed using 3D electromagnetic simulations. FR4-type dielectric substrate has been used due to its low cost. The ...
Random Test Generation from Regular Expressions for Graphical User Interface (GUI) Testing
(Institute of Electrical and Electronics Engineers Inc., 2019)
Generation of test sequences, that is, (user) inputs - expected (system) outputs, is an important task of testing of graphical user interfaces (GUI). This work proposes an approach to randomly generate test sequences that ...
Towards Uniform Modeling and Holistic Testing of Hardware and Software
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper introduces an approach to uniform modeling and testing of hardware and software systems and their faults. As an example, for hardware under consideration, designs at a behavioral level will be used, implemented ...
Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
(Elsevier Sci Ltd, 2013)
In this study, porous beta-Si3N4 ceramics containing limited amount of Sm2O3 and CaO as sintering aids were produced by addition of potato starch (10 and 20 vol.%) and partial sintering. Two different Si3N4 powders, alpha- ...
Morphology effect on electrochemical properties of doped (W and Mo) 622NMC, 111NMC, and 226NMC cathode materials
(Pergamon-Elsevier Science Ltd, 2020)
An investigation was carried out on layered Li(NixMnyCo1-x-y)O-2 (NMC) cathode active materials for Li-ion batteries to determine the effect of morphology on their electrochemical performances. The NMC active materials ...
Long-term and extreme wave climate of the Black Sea
(World Scientific Publ Co Pte Ltd, 2005)
In order to find out the wave climate affecting the whole Black Sea and the Turkish coasts on other seas, a comprehensive research project, called NATO TU-WAVES Project, was carried out during 1994-2001 with a generous ...
Utilizing Infrared technologies as a non-destructive evaluation for maintenance of concrete structures
(Crc Press-Taylor & Francis Group, 2015)
The aging of road infrastructure is becoming a serious problem worldwide. Although the number of aged structures is increasing rapidly, inspection and maintenance for them cannot catch up with the speed due to the limited ...
Large magnetocaloric effects in magnetic intermetallics: First-principles and Monte Carlo studies
(E D P Sciences, 2015)
We have performed ab initio electronic structure calculations and Monte Carlo simulations of frustrated ferroic materials where complex magnetic configurations and chemical disorder lead to rich phase diagrams. With lowering ...
Fuzzy PID Type STR based on SVR for Nonlinear Systems
(Ieee, 2017)
In this study, generalized self-tuning regulator (STR) based on support vector regression (SVR) which was previously introduced [1] is deployed to control a continuously stirred tank reactor (CSTR) system. The parameters ...
