Mikroskobik sistemlerde var olan odaklama derinliği sebebiyle kan hücreleri bulunan numuneler tamamıyla odaklı görüntülenememektedir. Bu durum yapay zeka ve görüntü işleme algoritmalarının performans kaybına sebep olabilmektedir. Bunu çözmek için odaklama derinliğinin artırılması yaklaşımları kullanılmakta ve numunenin optimum odaklı görüntüsü elde...

Depth of focus (DOF) is defined as the axial range in which the specimen stage moves without losing focus while the imaging apparatus remains stable. It may not be possible to capture an image that includes the entire specimen in focus due to the narrow DOF in microscopic systems. Extended depth of focus (EDOF) is used to overcome this limitation i...

During microscopic examination process, experts firstly determine the most appropriate focusing point by precisely moving the microscope stage in the Z axis. This manual focusing process may cause variability in results depending on hand-eye coordination and individual experience. Therefore, the development of automatic focusing offers superior qua...

Mikroskobik sistemlerde var olan odaklama derinliğinden dolayı numunenin tüm alanının odaklandığı görüntü elde etmek imkânsız olabilmektedir. Bu durum, mikroskobik sistemlerde görüntü işleme ve yapay zekâ algoritmaları kullanılarak gerçekleştirilen sınıflandırma, bölütleme, hizalama (registration), panoramik birleştirme (stitching) gibi uygulamalar...

To reduce potential threats to public health and economic losses, water distribution systems, which are critical parts of industrial control systems, require accurate and effective anomaly detection. The successful incorporation of machine learning models into anomaly detection procedures has been made possible by recent developments in computer sc...

Mikroskobik sistemlerde doku veya hücre numunelerinde nükleer morfoloji veya biyolojik belirteçler gibi bölümleri görselleştirmek için hematoksilen ve eozin (Hematoxylin and eosin - H&E) histolojik boyamalar, immünohistokimyasal (immunohistovhemical - IHC) ve immünofloresan (immunofluorescence - IF) boyama yaklaşımları geliştirilmiştir. H&E veya IH...

Electrocardiogram (ECG) signal which is composition of multiple segments such as P-wave, QRS complex and T-wave plays a crucial role in evaluating human heart cardiac diagnosis. For an analysis of cardiac diagnosis, it is required that clinicians scan the ECG signal for R-peaks (the highest peak of the QRS complex) detection, which relies on their...

There has been a significant increase in the use of more than one drug, especially in recent years. Concomitant use of medications by a patient can lead to drug-drug interactions, which are defined as drug-to-drug reactions. In order to prevent adverse situations, it is necessary to predict the interactions that may occur between drugs. The pre...

Electrocardiogram (ECG) signal, which is composite of multiple segments such as P-wave, QRS complex and T-wave, plays a crucial role in the treatment of cardiovascular disease. For an analysis of cardiac diagnosis, it is required that clinicians scan the ECG signal for QRS complex or R-peaks (the highest peak of the QRS complex) detection, which re...

Shape From Focus (SFF), which does not require any additional hardware in the 3D shape creation process, is one of the most preferred strategies. The SFF strategy uses a series of 2D images with different focusing on the process of creating 3D shapes of objects and consists of three basic steps: (1) Obtaining a 2D image series with different fo...

Background and objective: The size, shape, and position of the pancreas are affected by the patient characteristics such as age, sex, adiposity. Owing to more complex anatomical structures (size, shape, and position) of the pancreas, specialists have some difficulties in the analysis of pancreatic diseases (diabetes, pancreatic cancer, pancreatitis...

Elektronik Sağlık Kayıtları(Electronic Health Record-EHR) kronik hastaların takibinde ve uzaktan tedavisinde önemli rol oynamaktadır. EHR kronik hastaların biyolojik işaretlerinden ve fizyolojik parametrelerinden oluşmaktadır. EHR doktorlara kronik hastaların uzun süreli sağlık işaretlerini inceleyebilme ve bu işaretlerden daha somut çıkarımlarda b...

Nowadays, developments in the medicine continue fastly. Technological devices developed on the basic of these developments are usually complex and its use isn't easy. In our studies, considering this situation, a wireless system which is used easyly by older adults is improved. Thanks to this system, patient's blood oxygen saturation, blood glucose...

Because of the increase in the number of people, medical problems increase and chronic diseases become more common. Medical data transfer between remote patients and health center can be provided by using information technology and telemedicine. In this study a system based web services is improved to monitor chronic patient with telemedicine. The...

Skaler denetim icin urun modeli LG-SV022IG5A-4 olan degisken frekans...

This study is conducted to improve the performance of Linear Permanent Magnet Synchronous Motor by using Scalar Control Method. To do this, open and closed loop control methods are used. The study is modeled with MATLAB / SIMULINK. Firstly, the Simulink model has been developed by using equations dq axis system of the motor. Then, a scalar control...

The devices such as mouse, keyboard used for controlling of computer have various limitations. The users must make physical contact with the devices and have a restricted away because of connection with wire to control computer by using these devices. Traditional communication devices for computer-person can't provide user wireless computer control...
