Fuzzy Logic Control System with Helicopter Takeoff and Landing

ALLAHVERDİ, Novruz | HACIMURTAZAOĞLU, Murat

In this study, fuzzy expert system is designed for the provision of helicopter takeoffs and landings by fuzzy logic. For this purpose, a model helicopter and the test platform have been created that helicopter movements can be tested. The vertical motion control on the axis defined by the fuzzy logic control system is provided for the helicopter with the generated test platform with four degrees of freedom. Fuzzy logic controller was designed with Arduino 2560 control board and Visual Studio 2010 C Sharp program for controlling helicopter model and analysis of motion control was made.

Deep Belief Networks Based Brain Activity Classification Using EEG from Slow Cortical Potentials in Stroke

ALLAHVERDİ, Novruz | ALTAN, Gökhan | KUTLU, Yakup

An electroencephalogram (EEG) is an electrical activity which is recorded from the scalp over the sensorimotor cortex during vigilance or sleeping conditions of subjects. It can be used to detect potential problems associated with brain disorders. The aim of this study is assessing the clinical usefulness of EEG which is recorded from slow cortical potentials (SCP) training in stroke patients using Deep belief network (DBN) which has a greedy layer wise training using Restricted Boltzmann Machines based unsupervised weight and bias evaluation and neural network based supervised training. EEGs ...Daha fazlası

A New Approach to Early Diagnosis of Congestive Heart Failure Disease by Using Hilbert-Huang Transform

ALLAHVERDİ, Novruz | KUTLU, Yakup | ALTAN, Gökhan |

Congestive heart failure (CHF) is a degree of cardiac disease occurring as a result of the heart's inability to pump enough blood for the human body. In recent studies, coronary artery disease (CAD) is accepted as the most important cause of CHF. This study focuses on the diagnosis of both the CHF and the CAD. The Hilbert-Huang transform (HHT), which is effective on non-linear and non-stationary signals, is used to extract the features from R-R intervals obtained from the raw electrocardiogram ddata. The statistical features are extracted from instinct mode functions that are obtained applying ...Daha fazlası

A Multistage Deep Belief Networks Application on Arrhythmia Classification

ALLAHVERDİ, Novruz | ALTAN, Gökhan | KUTLU, Yakup

An electrocardiogram (ECG) is a biomedical signal type that determines the normality and abnormality of heart beats using the electrical activity of the heart and has a great importance for cardiac disorders. The computer-aided analysis of biomedical signals has become a fabulous utilization method over the last years. This study introduces a multistage deep learning classification model for automatic arrhythmia classification. The proposed model includes a multi-stage classification system that uses ECG waveforms and the Second Order Difference Plot (SODP) features using a Deep Belief Network ...Daha fazlası

A Study of Sound Transmission Loss for Building Materials Using Simulative and Experimental Approaches

MENDİ, Engin

The sound insulation models that we use in this study are based on theoretical computations and their aim is to reduce time, labor and cost consumption during the calculation of “Sound Transmission Loss (R)” of a particular material experimentally. In this study, for 11 different materials, we compare the performance of various simulation models with the experimental results that are already available in the literature. The experiments were carried out with Bastian, Akuzoft, Insul and dBKAisla model. The analyses were conducted in the standards of ISO 12354, ISO 10140 and ISO 717 in 1/3 octave ...Daha fazlası

Diagnosis of Coronary Artery Disease Using Deep Belief Networks

ALLAHVERDİ, Novruz | KUTLU, Yakup | ALTAN, Gökhan

In this study, a decision-support system is presented to aid cardiologists during the diagnosis and to create a base for a new diagnosis system which separates two classes (CAD and no-CAD patients) using an electrocardiogram (ECG). 24 hour filtered ECG signals from PhysioNet were used. 15 second short-term ECG segments were extracted from 24 hour ECG signals to increase the number of samples and to provide a convenient transformation in a short period of time. The Hilbert-Huang Transform, which is effective on non-linear and nonstationary signals, was used to extract the features from short-te ...Daha fazlası

Effective 3D Surface Modeling for Geographic Information Systems

MENDİ, Engin | ALPARSLAN, Mesut | YÜKSEK, Kemal

Abstract. In this work, we propose a dynamic, flexible and interactive urban digital terrain platform with spatial data and query processing capabilities of geographic information systems, multimedia database functionality and graphical modeling infrastructure. A new data element, called Geo-Node, which stores image, spatial data and 3-D CAD objects is developed using an efficient data structure. The system effectively handles data transfer of Geo-Nodes between main memory and secondary storage with an optimized directional replacement policy (DRP) based buffer management scheme. Polyhedron st ...Daha fazlası
