Article Can Computers Read a Text With Stress?(Ahmet Yesevi Univ, 2013) Uslu, I. Baran; Demir, Nurettin; Ilk, H. Gokhan; Yilmaz, A. Egemen; Department of Electrical & Electronics EngineeringToday prosodic elements such as stress, intonation and melody can be examined through computer-assisted techniques. The identification and analysis of acoustic qualities provide significant clues as to the suprasegmental aspects of speech. In this study a system was designed to enable speech synthesis using a Turkish text. This synthesizer was used to analyze the melodic sructures of selected sentences. Any speech synthesized by a computer needs to be equipped with a melodic model so that it will sound natural to the ear. Within the context of this study a melodic model was also suggested, and the elements of this model were analyzed and discussed in terms of the rules of linguistics.Article Citation - WoS: 5On Some Fixed Point Results in Extended Strong b-spaces(int Center Scientific Research & Studies, 2018) Alqahtani, Badr; Karapinar, Erdal; Khojasteh, FarshidIn this paper, we propose a notion of a strong extended b-metric space and investigate the existence and uniqueness of a fixed point of certain operators.Article Citation - WoS: 4An Eye-Controlled Wearable Communication and Control System for Als Patients: Smarteyes(Yildiz Technical Univ, 2017) Sumer, Emre; Uslu, I. Baran; Turker, MustafaALS (Amyotrophic Lateral Sclerosis) is a progressive neurodegenerative disease that involves the malfunctioning of motor neurons. The ability of the brain to initiate and control muscle movement is lost subsequent to death of motor neurons. People with ALS present the greatest challenge regarding communication issues. Besides, caring for a loved one with ALS is not an easy task. In this study, we developed an eye-controlled wearable system called "SmartEyes" which improves the life qualities of ALS patients and their caregivers by offering two important skills. The first skill is communicating through predefined voice messages generated by a computer and the second one is controlling several peripherals located in the patient's environment. The developed system is novel in that; the patients can easily vocalize their needs and requests with a few sequential eye movements. Moreover, they can control several household items including desk lamp, rolling curtain, television and air conditioner in the same way. The preliminary experiments showed that the performance of the system is satisfactory. The accuracy of the system commands based on pupil gaze direction was tested on several users and about an accuracy of 89% was achieved. It is believed that the developed system has attracted the patients' and their caregivers' interest very much and this is the main motivation in improving our system.Article Citation - WoS: 9Citation - Scopus: 12Some Integral Type Common Fixed Point Theorems Satisfying Φ-Contractive Conditions(Belgian Mathematical Soc Triomphe, 2014) Chauhan, Sunny; Karapinar, ErdalIn this manuscript, we obtain some common fixed point results of two pairs having the common limit range property in the setting of integral type contraction in the framework of symmetric (semi-metric) spaces. Moreover, we extend our results from two pairs of self-mappings to four finite families of self mappings to get common fixed points. Our results improve and extend a host of previously known results. Further, we establish some illustrative examples to show the validity of the main results.Article Citation - WoS: 1Remarks on Coupled Fixed Point Theorems in Partially Ordered Metric Spaces(int Center Scientific Research & Studies, 2012) Karapinar, ErdalIn this manuscript, we prove new coupled fixed point theorems extending some recent results in the literature on this topic. We also present applications of these new results through a number of examples.Article Citation - WoS: 3Citation - Scopus: 3How Do Implant Threads and Diameters Affect the All-On Success? a 3d Finite Element Analysis Study(IOS Press BV, 2022) Zor,Z.F.; Klllnç,Y.; Erkmen,E.; Kurt,A.; Kilinc, YelizBACKGROUND: The effect of different thread designs and diameters on the all-on-four concept is unclear. OBJECTIVE: The aim of the study was to clarify the differences in stress distribution of dental implants with various thread designs and diameters based on the all-on-four concept with three dimensional (3D) finite element analysis (FEA). METHODS: A 3D model of a totally edentulous mandible was used to perform the FEA. Four different models (M1, M2, M3, and M4) including 3.5 and 4.3 mm diameter dental implants with active and passive threaded designs were generated. The dental implants were positioned according to the all-on-four concept. The Von Mises stresses on dental implants and maximum and minimum principal stresses (Pmax and Pmin) on bony structures were calculated under vertical, oblique and horizontal loads. RESULTS: For Von Mises stresses, the highest stress values were detected on the distal implants for all models. Distal implants had also the highest stress values for vertical loading. The Von Mises stresses were found to be concentrated around the implant's neck. In all models the highest Pmax and Pmin stresses occurred in the bone surrounding the distal implant. It was noted that the active threaded implants showed the highest Pmax and Pmin stress values. CONCLUSION: The implant thread design and diameter might have a strong influence on the stress values in the all-on-four concept. © 2022 - IOS Press.

The samples were collected from the products of the different cleaning circuits of the operating plant. The concentrations of twelve potentially hazardous trace elements, including As, Cd, Co, Cr, Hg, Mn, Ni, Pb, Se, Th and U in those samples were determined. Compared with the average concentration of the trace elements in Turkish coals, the run-of-mine coal fed to the existing plant appears to contain higher concentrations of Cd, Hg, Mn, Th and V. However, the concentrations of As, Cd, Cr, Mn, Se, Th, U and V of the run-of-mine coal are above the world averages. Cd, Cr, Hg, Mn, Pb and Th concentrations of run-of-mine coal were easily removed at commercial coal preparation plant refuse in the range of 51.8% to 77.4 %, while only a small reduction was achieved for U and V as they were concentrated in clean coals. The present study reveals that conventional coal preparation technologies could significantly reduce hazardous air pollutants concentrations in coal.Article Citation - WoS: 5Citation - Scopus: 5Automorphisms of the mapping class group of a nonorientable surface(Springer, 2017) Atalan, Ferihe; Szepietowski, BlazejLet S be a nonorientable surface of genus g >= 5 with n >= 0 punctures, and Mod(S) its mapping class group. We define the complexity of S to be the maximum rank of a free abelian subgroup of Mod(S). Suppose that S-1 and S-2 are two such surfaces of the same complexity. We prove that every isomorphism Mod(S-1) -> Mod(S-2) is induced by a diffeomorphism S-1 -> S-2. This is an analogue of Ivanov's theorem on automorphisms of the mapping class groups of an orientable surface, and also an extension and improvement of the first author's previous result.Article The Early Turkestani Émigré Struggle and Turkestanism: Nation - Imagining in Emigration:1925-1940(2016) Karasar, Hasan AliErken dönem muhaceretteki Türkistanlıların mücadeleleri vatan dışında \"Milli Kimlik Tasavvuru\" oluşturma gayretlerinin önemli bir örneğidir. Bu makalede ülkeleri Bolşevikler tarafından ele geçirildikten sonra vatanlarını terk eden Türkistanlı milliyetçi liderlerin karşılaştıkları fikirsel sorunların bir kısmı ele alınmaktadır. Özellikle de muhaceret liderleri ve Türkçü düşünürlerden Zeki Velidî Togan, Mustafa Çokayoğlu, Osman Hoca ve Nihal Atsız'ın kimlik merkezli tartışmalarına değinilmektedir. Bu çalışmada siyasa yapımı, propaganda taktikleri, dergi neşriyatı ile medya kullanımı ve sivil toplum örgütlenmesi yolları ile muhaceretteki Türkistanlıların Ruslara karşı birleştirilmelerine çalışılmasına öncelik verilmiştir. Muhaceretteki liderlerin vatandan izole ancak vatandaki problemleri yanlarına alarak başlattıkları bu mücadelenin de ana öğelerinden biri kimlik siyaseti olmuştur.Article Citation - WoS: 6Removal of Hazardous Air Pollutants Based on Commercial Coal Preparation Plant Data(oficyna Wydawnicza Politechniki Wroclawskiej, 2013) Ozbayoglu,G.This paper investigates the concentration, distribution, and rejection of hazardous air pollutants, specifically identified by the US Clean Air Act Amendments of 1990, based on commercial coal preparation plant data obtained on-site.
