Turkish Sign Language Animation with Motion Capture

SÖYLEV, Arda | MENDİ, Engin

In this paper, using motion capture, we study on Turkish Sign Language Animation. A markerless system, Microsoft Kinect sensor and a professional optical system are compared. Besides, we use the motion capture data in two different approaches; data driven and real time. To animate the sign language, we merge the motion capture output with a cartoon character. In the first approach, which is data-driven, motion capture data is recorded, processed and converted to a character animation off-line. This data is stored in a database and it can be used in mobile devices or any other necessary ways. R ...Daha fazlası

Kümeleme Analizi: Bir İhracat Sofistikasyonu Uygulaması

CURA, Fatih | CANITEZ, Murat | GÜNDÜZ, Mehmet Akif

Uluslararası ticarete dair istatistikler genellikle ürünlere ve ülkeler arasındaki ticaret miktarlarına göre sınıflandırılmaktadır. İhracat sofistikasyonu ise ülkelerin ihracat büyüklüklerinin ne kadar sermaye yoğun ürün bileşimine sahip olduğunu gösteren yeni bir ölçüm yöntemidir. İhracatçı ekonomilerin gelir düzeylerine, araştırma geliştirme harcamalarına ve birim ihracat fiyatlarına dayalı bir gelişmişlik endeksi olarak da ifade edilebilecek ihracat sofistikasyonu sayesinde, ülkeler ihracatlarında sofistike olmaları bakımından nitelendirilebilmektedir. Bu çalışmada ülkelerin her GTİP fasıll ...Daha fazlası

Z-boson production in p-Pb collisions at √sNN = 8.16 TeV and Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Measurement of Z-boson production in p-Pb collisions at √ sNN = 8.16 TeV and Pb-Pb collisions at √ sNN = 5.02 TeV is reported. It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity −4 < ηµ < −2.5 and transverse momentum p µ T > 20 GeV/c in the laboratory frame. The invariant yield and nuclear modification factor are measured for opposite-sign dimuons with invariant mass 60 < mµµ < 120 GeV/c 2 and rapidity 2.5 < yµµ cms < 4. They are presented as a function of rapidity and, for the Pb-Pb collisions, of centrality as well. The results are compared with t ...Daha fazlası

The impact of imiquimod on radiation-induced lung injury: Results of an experimental study Imiquimod attenuates radiation lung injury

ÇALIK, Mustafa | ÇALIK, Saniye Göknil | YAVAŞ, Güler | ÇELİK, Zeliha Esin | YAVAŞ, Çağdaş | SARGON, Mustafa Fevzi | ESME, Hıdır

Aim: Radiation-induced lung injury (RILI) is a major dose-limiting factor during thoracic irradiation. Imiquimod (Imq) is a heterocyclic amine that has been shown to be effective in diseases related to inflammation and fibrosis. In this study, we aimed to evaluate the impact of Imiquimod on RILI. Material and Method: The study included 60 adult female Wistar-Albino rats (250-300 g). Rats were divided into 6 groups: Group (G) 1: control, G2: radiotherapy (RT) only, G3 and G4: 5 and 10 mg/kg Imq, G5 and G6 RT: plus 5 and 10 mg/kg Imq groups respectively.

Real-Time Resistor Color Code Recognition using Image Processing in Mobile Devices

DEMİR, Muhammed Fatih | ÇANKIRLI, Ayşenur | KARABATAK, Begüm | YAVARIABDI, Amir | MENDİ, Engin | KUSETOĞULLARI, Hüseyin

This paper proposes a real-time video analysis algorithm to read the resistance value of a resistor using a color recognition technique. To achieve this, firstly, a nonlinear filtering is applied to input video frame to smooth intensity variations and remove impulse noises. After that, a photometric invariants technique is employed to transfer the video frame from RGB color space to Hue-Saturation-Value (HSV) color space, which decreases sensitivity of the proposed method to illumination changes. Next, a region of interest is defined to automatically detect resistor's colors and then an Euclid ...Daha fazlası

Vagal schwannoma of the posterior mediastinum with cervical extension Vagal schwannoma with cervical extension

ESME, Hıdır | ÇALIK, Mustafa | ÇALIK, Saniye Göknil

A 35-year-old male was admitted to our Emergency Department with chest pain and hoarseness lasting for a month. A well-defined 58x36x34 mm mass located in the left posterior mediastinum with cervical extension was found on radiological imaging. It was completely excised with transversal cervicotomy and left-sided video-assisted thoracoscopic surgery. Schwannomas originating from the intrathoracic vagus nerve are extremely rare. Due to its rarity, similarity with other mediastinal lesions and unusual localization, diagnosis can be missed easily in busy and crowded Emergency Department. Here, th ...Daha fazlası

Penetrating Lung Injury Caused by a Close-range Blank Cartridge: Case Report

ÇALIK, Saniye Göknil | ÇALIK, Mustafa | ŞAHSIVAR, Mehmet Orkun | DAĞLI, Mustafa | ESME, Hıdır

A 17-year-old male was brought to the emergency department with chest injury by a gunshot from a blank cartridge (BC). No bullet or fragment was seen in the radiological examination. The patient underwent left thoracotomy for hemopneumothorax. Chest injuries due to BCs have rarely been reported in the literature. The word ``blank{''} gives people a false sense of safety. Although BC ammunition does not contain any bullets or parts coming out of the barrel, it can lead to serious injury or even death, especially at contact or close-range.
