Effect of internal derangements and degenerative bone changes on the minimum thickness of the roof of the glenoid fossa in temporomandibular joint

Hatice Cansu KIŞ

Objectives: The aim of this study is to investigate the effect of internal derangements and degenerative bone changes on the minimum thickness of the roof of the glenoid fossa (RGF). Methods: MRI and cone beam CT records of temporomandibular joints (TMJ) of 68 patients were evaluated retrospectively in this study. The joints were divided into three groups according to TMJ disc status which had been diagnosed in MRI: normal disc status, anterior disc displacement with reduction, and anterior disc displacement without reduction. Cone beam CT was used to evaluate the degenerative bone changes of ...Daha fazlası

The evaluation of the mandibular bone structure changes related to lactation with fractal analysis

Hatice Cansu KIŞ

Objectives Lactation-induced bone loss of lumbar spine, hip, femur and distal radius are well documented in the literature. The aim of this article is to investigate whether lactation afects the trabecular and cortical bone structure of human mandible. Methods 120 dental panoramic radiographs (DPR) of the lactating women who were breastfeeding for 3–6 months (study group) and 120 DPRs of the nulliparous women (control group) were evaluated. Regions of interest (ROI) were chosen from the geometric center of ramus, the geometric center of angulus and the cortical bone. ROIs were examined with fr ...Daha fazlası

Kaotik haberleşme sistemleri için yeni bir uyarlanır kör kanal denkleştirici

Ali ÖZEN

Bu bildiride, kaotik haberleşme sistemleri için bulanık mantık üzerine kurulan yeni bir kör kanal denkleştirici önerilmektedir. Klasik haberleşme sistemleri için ters süzgeçleme kriterleri (Inverse Filtering Criteria, IFC) tabanlı algoritma, süper üstel algoritma (Super Exponential Algorithm, SEA) ve sabit genlik algoritması (Constant Modulus Algorithm, CMA) en popüler üç kör kanal denkleştirme algoritmasıdır. Ancak bu algoritmalar, kaotik haberleşme sistemleri için istenen başarım değerlerinde yeterli olmamakta ve geliştirilmeleri gerekmektedir. Bu çalışmada, kaotik haberleşme sistemleri için ...Daha fazlası

QAM signaling over kappa - mu shadowed fading channels

Mehmet BİLİM

In this study, average symbol error rate (ASER) expressions for rectangular quadrature amplitude modulation (RQAM) and cross quadrature amplitude modulation (XQAM) over κ−μ shadowed fading are proposed by considering two different system models. In the first system model, a single-input– single-output (SISO) scheme is considered while a multiple-input–multiple-output (MIMO) with single transmit antenna selection and maximal ratio combining (TAS/MRC) is investigated as a second system model. First, the exact, approximate and asymptotic ASER expressions of RQAM and XQAM for a SISO system model a ...Daha fazlası

Analysis of analytical capacity forFisher–SnedecorFfading channels withdifferent transmission schemes

Mehmet BİLİM

This Letter presents capacity analysis of Fisher–SnedecorFfadingchannels under different transmission strategies. To this end, novelanalytical expressions are proposed for optimal rate adaptation withconstant transmit power, channel inversion with afixed rate and trun-cated channel inversion withfixed rate schemes in this Letter. Then,analytical results are illustrated for different fading and shadowingparameter values.

2 Stages-region-based p300 speller in brain-computer ınterface

Zeki ORALHAN

Brain–computer interface (BCI) applications present communication model without using peripheral nerves and neuromuscular systems. The P300 waves are used in BCI applications. Signal classification accuracy is a significant parameter for P300 BCI application. In this study, our goal is to investigate P300 speller structure for higher classification accuracy. There are a lot studies about P300 speller variations of stimulus model. This models mostly includes about row–column-based visual or audio stimuli model P300 spellers. But there is not enough study about region-based P300 spellers. This s ...Daha fazlası

Project staff scheduling with theory of coalition

Oğuzhan Ahmet ARIK | Erkan KÖSE

Project scheduling has been still one of the hottest topics in the management area. The goal of traditional project management is to complete the project at the earliest possible time in accordance with the available resources without violating priority relations of the activities involved. Unlike traditional project management, this study deals with the possibility of a coalition among the staf available to accomplish tasks of the project. The tasks can be fulflled by more than one staf members. Staf’s coalition shortens the completion time of the tasks. A natural problem that arises in this ...Daha fazlası

Locating unmanned aircraft systems for multiple missions under different weather conditions

Erkan KÖSE

Motivated by the increasing civilian use of Unmanned Aerial Vehicles (UAVs), this paper considers the simultaneous location and routing of UAVs for multiple missions and diferent weather conditions. We include modeling and computational experience inspired by requirements for air surveillance by the Turkish government’s public agencies. We model these demands in multiple mission areas and consider the impact of diferent weather conditions on the ability to employ UAVs from diferent geographic locations. We formulate the problem as a two-stage stochastic integer linear program with recourse and ...Daha fazlası

İki aşamalı tedarik zinciri koordinasyonunun bulanık talep altında analizi

Gülçin CANBULUT

Çalışmada; bir tedarikçi ve bir perakendeciden oluşan iki aşamalı bir tedarik zinciri yapısı talep değişkeninin bulanık parametre olması durumunda incelenmiştir. Tedarik zinciri üyelerinin her birinin farklı hedefleri bulunmakta ve kendi performanslarını optimum yapmayı istemektedirler. Bu sebeple tedarik zinciri üyeleri arasındaki koordinasyonun sağlanması gerekmektedir. Bu koordinasyona göre tedarik zincirleri; merkezi ve merkezkaç tedarik zincirleri olarak değerlendirilmektedir. Çalışmada merkezi ve merkezkaç tedarik zinciri modelleri için talep parametresinin bulanık değişken olması şartıy ...Daha fazlası
