TiO2 nanotube coating on stainless steel 304 for biomedical applications
(
Elsevier Ltd
, 2015 , Article)
The present study describes the anodic growth of TiO2 nanotube thin layer on stainless steel 304 in ethylene glycol/water/ammonium fluoride electrolyte. In this regard, pure titanium was coated on stainless steel 304 ...
Stable and effective super-hydrophilic polysulfone nanofiber mats for oil/water separation
(
Elsevier Ltd
, 2015 , Article)
Hydrophobicity of polysulfone is the main constraint facing wide application in the most important field; water treatment, although this polymer shows promising characteristics to be used in different separation technologies. ...
Spiderweb Honeycombs
(
Elsevier Ltd
, 2015 , Article)
Small and large deformation in-plane elastic response of a new class of hierarchical fractal-like honeycombs inspired by the topology of the “spiderweb” were investigated through analytical modeling, detailed numerical ...
Electroencephalography simulation hardware for realistic seizure, preseizure and normal mode signal generation
(
American Scientific Publishers
, 2015 , Article)
Unlike the ECG and EKG simulators which are very commonly used for these applications, there is a big need for seizure related EEG simulator. Having a hardware system that can be used instead of a real patient to generate ...
Removal of disinfection by-product precursors by coagulation and an innovative suspended ion exchange process
(
Elsevier Ltd
, 2015 , Article)
This investigation aimed to compare the disinfection by-product formation potentials (DBPFPs) of three UK surface waters (1 upland reservoir and 2 lowland rivers) with differing characteristics treated by (a) a full scale ...
Mitigation of railway-induced vibration by using subgrade stiffening
(
Elsevier Ltd
, 2015 , Article)
Railway-induced ground vibration is often associated with sites with soft ground. Stiffening of the subgrade beneath the railway track is one particular measure that has potential to reduce the vibration level at such ...
Intention recognition in manufacturing applications
(
Elsevier Ltd
, 2015 , Article)
In this article, we present a novel approach to intention recognition, based on the recognition and representation of state information in a cooperative human-robot environment. States are represented by a combination of ...
Optimal design of hybrid renewable energy systems in buildings with low to high renewable energy ratio
(
Elsevier Ltd
, 2015 , Article)
We develop a simulation-based meta-heuristic approach that determines the optimal size of a hybrid renewable energy system for residential buildings. This multi-objective optimization problem requires the advancement of a ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
Common-mode voltage and vibration mitigation of a five-phase three-level NPC inverter-fed induction motor drive system
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Common-mode (CM) voltage is one of the main reasons for the flow of bearing currents in induction motors (IM) that ultimately leads to the bearing failure and causes severe vibrations. For three-phase IM drives, many works ...
