It is known that accuracy of time estimation depends on time perception and it is affected by various internal and external factors. However, it is a field that there is a few research on exploration of neurophysiological basis of this relations. These limited number of studies are found to be designed based on basic and static stimuli. On the other hand, time percpetion in real life stiuaion requires...
Thermoresponsive hydrogels have great potential in biomedical applications such as drug delivery systems and tissue engineering. Synthesis of hydrogels from renewable resources attracts attention day by day. In this study special type of thermoresponsive hydrogels were synthesized. These hydrogels are cross-linked hydrophilic polymers containing some biocompatible moieties which are derived from plant...
The number of wind energy plants in energy production is rapidly increasing in many countries of the world. In recent years, as an alternative energy source, it has been observed that wind energy installations have been established in various regions of our country. Wind turbines are sometimes discussed with the concern that the electromagnetic fields around them can cause health problems. In this...
To extend the concept of the memristive systems to capacitive systems, memcapacitive systems have been described in 2009. Memcapacitors which are a subset of memcapacitive systems are flux-dependent nonlinear circuit elements with memory. Materials with memcapacitive properties has already been reported in literature. The elusive memcapacitor show promise for new type of applications because of their...
Left ventricular assist devices (LVADs) have become one of the most effective treatment modalities for end-stage congestive heart failure, particularly where heart treatment becomes a limited option due to donor shortages. The development of local (national) technologies, therefore, emerges as a medical, technical, scientific, humanitarian and economic necessity. The mathematical models used for concept...
Toxicity tests are required to detect the possible effects of pollutants on organisms. This study investigates the effect of Chemical Oxygen Demand (COD), suspended solid (SS) and pH parameters on toxicity of textile industry wastewaters except for the color parameter, effect of which is well known. Fish bioassay taking place in legal regulation of Turkey was used as toxicity test. At the end of the...
In the modern world, cancer has increasingly become a health problem. It has been listed as the first three disease among the ‘cause-known deaths’ in our country. Malignant Melanoma, one of the skin cancer types, is the cause of 75% of all skin cancer related deaths even though it is 4% of all skin cancer cases. The examination of the diseases are diagnosed through visual inspections by the dermatologists...
The Travelling Salesman Problem is defined as returning to the starting point after visiting all the points with the least cost. In this study, a real-world application that calculates the route of the Travelling Salesman Problem using the current traffic intensity information from Google Maps is prepared. Different methods such as Exhaustive Search, Heuristic A-Star Search, BitMask Dynamic Programming,...
In this work, a new method for discrimination between normal and heart murmurs sound is presented. Statistical parameters, such as standard deviation (SD), are extracted from two datasets of heartbeats. Several classification technics, such as Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Naïve Bayes (NB), discriminative analysis, and classification tree, are used. Simulation results obtained...
With the development of new applications, the number of users in telecommunication networks is increasing considerably. Cognitive radio (CR) is a promising solution to manage radio resources by opening up the underutilized parts of the licensed spectrum for secondary reuse. A proper radio resource management (RSM) policy should be implemented to improve overall network performance with paying regard...
Diabet is one of the metabolic trouble which is generally occurs genetic and environmental components. It happens increasing of blood level. In this study, diabet illness has been diagnosed with its features by classification with support vector machines (SVM) and artificial neural networks (multi layer perceptron). The method used for diagnosis is aritificial neural networks multi layer perceptron...
Electroencephalography (EEG), as the most common tool for epileptic seizure classification, contains useful information about different physiological states of the brain. Seizure related features in EEG signals can be better identified when localized in time-frequency basis projections. In this work, a novel method for epileptic seizure classification based on wavelet packets (WPs) is presented in...
The main purpose of this study is to overcome the difficulties experienced by the mothers during the sleeping period of the babies and to put the babies to sleep in a comfortable and peaceful way as if the babies were in the mother's lap. In this direction, the motion that the mother made while sleeping her baby on the lap was modeled, and a cradle designed to repeat mother movements based on this...
A mathematical model of cell-autonomous mammalian circadian clock is integrated into an adaptive control scheme. We analyze circadian clock rhythms with time delayed biophysically meaning parameter sets to generate self-oscillation behavior of a SCN neuron (Suprachiasmatic Nucleus Neuron). We demonstrate how an adaptive control scheme is utilized to stabilize of time varying mRNA and protein expression...
Today Biosafety cabins are signed in various ways with the aim of preventing authorized personnel from being exposed to hazardous biological materials during laboratory work. In this work, our goal is to protect the authorized personnel from the possible infections and to provide a realistic work comfort. For this purpose, we design a remote control unit, which is simulates wrist movements simultaneously...
Telemedicine has started to be beneficial to patients in remote regions. It is very important to monitor the ECG signals of these patients with heart disorders. Developments in information technology have started to provide important contribution to the clinical decision support systems for early detection and diagnosis. This study aimed to be part of clinical decision support systems and used easily...
Echo cancellation has always in the preprocessing steps before the signals are converted to feature vectors and pattern classification. This is always the correct flow of speech identification. Therefore, in order to get the best cleaned signal, the usage of adaptive echo cancellation removed the echo and also the noise which deteriorates the signals and final results during classification process...
The brain is one of the most complex and integrated organ in the human body which directs our muscle movements, our breathing and internal temperature, furthermore every imaginative sight, perception, and diagram are derived by the brain. The brain's neurons are effected by internal and external stimulations. Those stimulations might have positive and negative influence on brain activity and structure...
