Assessment of surgeon's stress level and alertness using EEG during laparoscopic simple nephrectomy
(IEEE, 2013)Laparoscopic simple nephrectomy (LSN) is an accepted treatment modality for nonfunctioning kidneys. Besides decreased postoperative morbidity, LSN is an advantage with decreased analgesic requirements and convalescence. ... -
Self-organizing maps for brain tractography in MRI
(IEEE, 2013)Brain white matter fibers can be mapped synthesizing the diffusion tensors obtained from diffusion weighted magnetic resonance images. An important drawback in the determination of the fiber paths for tractography purposes ... -
A new method for fabrication of nanohydroxyapatite and TCP from the sea snail cerithium vulgatum
(Hindawi Publishing Corporation, 2014)Biphasic bioceramic nanopowders of hydroxyapatite (HA) and ß-tricalcium phosphate (TCP) were prepared from shells of the sea snail Cerithium vulgatum (Bruguière, 1792) using a novel chemical method. Calcination of the ... -
White Matter Changes in Thalamic Stroke
(IEEE, 2014)Stroke as one the most significant health problems can be diagnosed by clinical symptoms and medical imaging modalities. Stroke patients mostly suffer from white matter changes, so the detection of any change in the white ... -
Improvement of design of a surgical interface using an eye tracking device (48, 2014)
(BIOMED CENTRAL LTD, 2014)… -
Göz Hareketleri Takibi ile Elit Sporcularda Bakış Karakteristikleri Analizi: Pilot Çalışma
(IEEE, 2014)Eye movements are essential for natural vision. Eye tracking technology is being used in research in many disciplines to examine the differences in the visual attention of experts and novices. Eye tracking research in ... -
Nano calcium phosphate powder production through chemical agitation from atlantic deer cowrie shells (Cypraea cervus Linnaeus)
(2014)The process is a simple chemical method and aims to produce nano-structured calcium phosphate powders from natural sources, for biomedical applications. For this purpose, Atlantic Deer Cowrie (ADC) shells (Cypraea cervus ... -
Preparation and evaluation of cerium oxide-bovine hydroxyapatite composites for biomedical engineering applications
(Elsevier, 2014)The fabrication and characterization of bovine hydroxyapatite (BHA) and cerium oxide (CeO2) composites are presented. CeO2 (at varying concentrations 1, 5 and 10 wt.%) were added to calcinated BHA powder. The resulting ... -
Nanostructured biomaterials with antimicrobial properties
(2014)The present review is intended to bring together the main advances in the field of nanostructured biomaterials with antimicrobial properties. It is generally accepted that the discovery of antibiotics was of great importance ... -
Extraction of Multiple Sclerosis Lesions in MR Images Based on Active Contours
(IEEE, 2015)In this study, a semi automatic segmentation of multiple sclerosis lesions in magnetic resonance (MR) images based on active contours is done. Based on the seed area selection by the user, the parametric active contours ... -
Bioceramic production from giant purple barnacle (Megabalanus tintinnabulum)
(Trans Tech Publications Ltd, 2015)In this study the structural and chemical properties of barnacle shell based bioceramic materials (i.e. hydroxyapatite, whitlockite, monetite and other phases) were produced by using mechano-chemical (hot-plate) conversion ... -
Design and Implementation of Brain Computer Interface Based on Wireless EEG Measurements: A Pilot Study
(IEEE, 2015)Brain computer interface (BCI), is a direct communication pathway between brain signals and an external device which often serves to support cognitive and emotional motor functions. The implementation and design of a human ... -
Magnetic Core Shell Structures: From 0D to 1D Assembling
(BENTHAM SCIENCE PUBL LTD, 2015)Material research and development studies are focused on different techniques of bringing out nanomaterials with desired characteristics and properties. From the point of view of materials development, nowadays scientists ... -

(IEEE, 2015)Diffusion tensor imaging (DTI) techniques allow the detection of changes in the microstructure of the human brain. The detection and follow-up of the underlying pathology and disruption of tissues is of vital importance. ... -
Silkfibroin-Ca-P composite bone replacement material for guided bone growth
(International Committee on Composite Materials, 2015)Mineralized natural protein based materials are investigated as novel materials to be used in tissue engineering and as bone replacement materials. Silk fibroin fiber based foams and films are used as mineralized composites ... -
Determining Phase Duration of Scanning EMG Signals
(IEEE, 2015)There are more than one motor unit activities recorded simultaneously during scanning EMG recordings. It is not possible to determine the phase duration correctly by inspecting only one sweep. The other motor unit activities, ... -
Investigation of the Effect of Fiber Diameter Variability via Recording from Tendon via of Single Fiber Electromyography
(IEEE, 2015)In this preliminary study, two muscle fibers which one of them had a constant fiber diameter and the other had a variable fiber diameter were created by using an EMG simulator. Single Muscle Fiber Action Potentials (SMFAPs) ...
