A Multistage Deep Learning Algorithm for Detecting Arrhythmia

ALLAHVERDİ, Novruz | KUTLU, Yakup | ALTAN, Gökhan

Deep Belief Networks (DBN) is a deep learning algorithm that has both greedy layer-wise unsupervised and supervised training. Arrhythmia is a cardiac irregularity caused by a problem of the heart. In this study, a multi-stage DBN classification is proposed for achieving the efficiency of the DBN on arrhythmia disorders. Heartbeats from the MITBIH Arrhythmia database are classified into five groups which are recommended by AAMI. The Wavelet packet decomposition, higher order statistics, morphology and Discrete Fourier transform techniques were utilized to extract features. The classification pe ...Daha fazlası

Hallucinative Perception In Architecture And Effects Of Holographic Platform On Design Process

SEVİM, Halil | DEMİRKAN, Özlem

The hologram is a hallucinative image that produced virtually in yellow spot (macula lutea) and embedded in the physical environment with the help of photons. The hardware that creates hallucinative image is a portable head mounted holographic platform computer. The holographic platform computer senses the physical environment with the help of integrated cameras, sensors and lenses on it. The computer processes the information of the physical environment and integrates the information of the virtual environment into the physical environment and presents a holographic image to the user. In this ...Daha fazlası

Biogas Potential Of Ereğli City

TUNÇEZ, Fatma Didem

Turkey's growth and development goals mean that its energy need will increase rapidly in proportion to its growth. Meeting the increasing energy need from fossil fuels such as coal, oil and natural gas causes the depletion of natural resources. Another problem is that the increase in energy demand is increasingly met with imports. The solution of this problem is to diversify the energy supply with renewable energy sources. Biogas is one of the renewable energy sources. Biogas potential of Ereğli District was revealed in this study.

The Visualization Of Third Space Through Marcus Hartel’s Street Shoots In NYC

DEMİRKAN, Özlem | SEVİM, Halil

Henry Lefebvre builds the production of space on three moments. These are perceived, conceived and experienced spaces. These three moments conceptually correspond to space practice, space representation, and representational spaces. Edward Soja develops his concept of thirdspace on Lefebvre’s three moments. Third space is the intersection and even combination of perceived and conceived space. The intersection and combination is lived and experienced space. He defines trialectics of being and trialectics of spatiality by setting out a voyage through Lefebvre’s works. He addresses to Foucault’s ...Daha fazlası

A Novel Immobilization Matrix For The Biosensing Of Phenol: Self Assembled Monolayers Of Calixarenes

TAŞÇI, Filiz | SAYIN, Serkan | AĞ SELECİ, Didem | DEMİR, Bilal | AZAK, Hacer | YILDIZ, Hüseyin Bekir | ODACI DEMİRKOL, Dilek | TİMUR, Suna

Aim: The development of calixarene based phenol biosensor. Methods: This study describes the application of a calixarene derivative, 5,17-diamino-25,27-bis(3-thiol-1-oxypropane)-26,28-dihydroxycalix[4]arene (HS-Calix-NH2) which has both amino and thiol functionalities, in the practical surface modifications for biomolecule binding. The structure of HS-Calix-NH2 allows easy inter-action with Au surface and one-step biomolecule immo-bilization. Self-assembled monolayers (SAMs) of p-amino-functionalized mercaptoalkylcalixarene (HS-Calix-NH2) were formed onto the Au electrode. Then, Laccase (Lac) ...Daha fazlası

The Function Analysis and its Application to Determination of Fuzzy Subsets for Model Helicopter Fuzzy Control

ALLAHVERDİ, Novruz | HACIMURTAZAOĞLU, Murat

In this study, an analysis of the function that determines the sub-clusters of the fuzzy controller for model helicopter control is performed. For this purpose, a model helicopter and a test platform were established in which the results of the function analysis can be seen and the application results will be examined. Arduino control card is used for model control. Analysis results are analyzed on computer using c # program. The computer connection with the model is carried out via the Usb port. Input parameters for control are obtained from the sensors on the model. The output values are cal ...Daha fazlası

Using Group Reading Instruction As An Alternative To Explicit Grammar Instruction To Teach English Grammar

ALTINBAŞ, Mehmet Emre

Throughout the history of English Language Teaching, teaching grammar has been one of the most important concepts. Different approaches, methods and techniques have been put forward regarding different ways of teaching grammar. Discovery learning and integrating grammar teaching with reading are among these ways through which English grammar can be taught. This study was conducted to test the effectiveness of a group reading instruction technique as an alternative to the traditional application of explicit teaching at a private university in Turkey. The study was carried out as an experimental ...Daha fazlası

Observation of Hot Tearing in Sr-B Modified A356 Alloy

ULUDAĞ, Muhammet | ÇETİN, Remzi | DIŞPINAR, Derya.

In this work, T-shaped mould design was used to generate hot spot and the effect of Sr and B on the hot tearing susceptibility of A356 was investigated. The die temperature was kept at 250°C and the pouring was carried out at 740°C. The amonut of Sr and B additions were 30 and 10 ppm, respectively. One of the most important defects that may exist in cast aluminium is the presence of bifilms. Bifilms can form by the surface turbulence of liquid metal. During such an action, two unbonded surfaces of oxides fold over each other which act as a crack. Therefore, this defect cause many problems in t ...Daha fazlası

Kırsal kalkınmada elektronik ticaretin rolü üzerine teorik bir inceleme

TUNCER, İlhamş | GÜNDÜZ, Mehmet Akif

Kırsal alanların geri kalmışlığı gelişmiş ve gelişmekte olan ülkelerin en önemli sorunu haline gelmiştir. Birçok ülke ve sivil toplum kuruluşu kırsal kalkınma bağlamında birçok önemli politikalar uygulamış ve proje üretmiştir. Üretim temelinde önemli derece mali kaynak sunmuştur. Ancak göz ardı edilen en büyük eksiklik kırsal alanda üretilen ürünlerin nasıl pazarlanıp satılacağıdır. Dünyada önemli ölçüde gelişen e-ticaret kırsal kalkınmada yaşanan pazarlama ve satış eksikliğinin en büyük tamamlayıcı faktörü olabilmesidir. Ayrıca, e-ticaret kırsal kesimdeki tüketici için de alım gücüne katkı sa ...Daha fazlası
