Cognitive functions and especially attention is very important function over whole life in humankinds. This makes attention is keystone for researchers not only cognitive health but also marketing, stage-gate process and education. In this work Mesulam's cancellation tests have been used. We examined attention levels of participants based on sex differences and identified effect on experiments. As...
In this study, we describe design principles and report the preliminary performance of a realized digital patient bed scale. Four of these scales are placed under each castor of a patient bed. Then, the patient weight is displayed on a digital weight indicator mounted on a separate controller board which communicates with each four channels of independent weight sensors via Bluetooth means.
Multi drug resistant strains of Staphylococcus aureus (S. aureus), which is a type of gram-positive bacteria that can cause infection, especially in the skin and many parts of the body. Over the years, strains of S. aureus have become resistant to existing antibiotics. This has led to the research and development of different treatment modalities to treat infections caused by multi drug resistant...
Parkinson's disease is a neurodegenerative disorder that affect human life quite negatively with motor, cognitive and psychiatric way. Recent electrophysiological experiments have shown that Basal Ganglia, spaced in the midbrain, can lead to Parkinsonism. Beta frequency oscillations and irregular burstings are most important symptoms of Parkinson's disease. They appear in Globus Pallidus and Subtalamus...
TÜBÍTAK UME Medical Metrology Laboratory has been doing researches to develop measurement infrastructure of high level medical systems at nationwide except for radiology studies. In this context, the laboratory has been developing national phantoms for testing and quality control of ultrasonic imaging systems and has been operating to establish measurement studies and reference standards over these...
Elektromyography (EMG) signals are the electrical signals that are emerged by muscular contraction. In this study, a wireless EMG device was designed and implemented. The EMG signals are collected by surface electrodes, processed with filters and amplifiers and sent to the computer via wireless module. The EMG signals are obtained and amplified by an instrumentation and an inverting amplifier. Then,...
In this study, vibrational resonance phenomena is investigated in excitable neuron population. Synapses where complex electrochemical events take place in is modelled dynamically, not statically by contrast with early studies. Effect of short-term synaptic depression which is a prominent feature of dynamic synapses on vibrational resonance is studied. The results of numerical simulations that silencing...
This The most commonly used method of permanent tattoo removing is lasers. Since lasers varying with different wavelengths have monochromatic (single wavelength) characteristics, only one type of laser can not affect all the tattoo colors. In order to overcome this disadvantage, more than one type of laser is used in multicolor (with more than one color) tattoos. The colors that are most difficult...
This project is the general design of the “Glove” system, which translates the sign language used by disabled people into a daily language. With this system, people with disabilities will be able to communicate comfortably even if people who disabled people talks do not know the sign language in daily life. This provides disabled people that handle their everyday tasks more easily. Before the general...
Ultrasound imaging and Fine Needle Aspiration Biopsy, which used for diagnosis of thyroid cancer, don't ensure sufficient sensitivity and specificity. Due to this fact, many patients undergo unnecessary thyroid removal. In this study, it is aimed to find new features based on non-invasive Computerized Tomography. 52 nodular goiter patients who underwent thyroid removal surgery with suspicion of cancer...
