Conference Object Agile Methods Adoption in Large Software Development Projects(Ieee, 2016) Mishra, Alok[No Abstract Available]Conference Object Citation - WoS: 1Gender Prediction by Using Local Binary Pattern and K Nearest Neighbor and Discriminant Analysis Classifications(Ieee, 2016) Camalan, Seda; Çamalan, Seda; Sengul, Gokhan; Şengül, Gökhan; Çamalan, Seda; Şengül, Gökhan; Information Systems Engineering; Computer Engineering; Information Systems Engineering; Computer EngineeringIn this study, gender prediction is investigated for the face images. To extract the features of the images, Local Binary Pattern (LBP) is used with its different parameters. To classify the images male or female, K-Nearest Neighbors (KNN) and Discriminant Analysis (DA) methods are used. Their performances according to the LBP parameters are compared. Also classification methods' parameters are changed and the comparison results are shown. These methods are applied on FERET database with 530 female and 731 male images. To have better performance, the face parts of the images are cropped then feature extraction and classification methods applied on the face part of the images.Conference Object Citation - WoS: 1Lip Shape Based Emotion Identification(Ieee, 2016) Gul, Nuray; Tora, HakanEmotion recognition systems have an important role to play in the human-computer interactive applications (HCI). These systems are using facial features of face images and they are verifying or identifying the emotions. In this study, emotion identification algorithms are improved by using just mouth region features of a face. Region of interest (mouth region) is detected by Viola-Jones algorithms from video frames which are including different emotional face expressions. Outer boundaries of lip shapes are extracted by manually and calculated the scalar Fourier Descriptors (FDs) of the boundaries. Classification and recognition of the emotions is presented according to scalar FDs of lip contours. Test results are obtained as 93.9 % accuracy rate for scalar FDs.Conference Object Design, Analysis and Manufacturing of Dielectric Rod Added Conical Rom Antennas(Ieee, 2016) Avcioglu, Esra; Özaslan, Alper; Caliskan, FatmaIn this study, ANSYS HFSS (High Frequency Structural Simulator) software had been used. By using this software, dielectric rod added conical horn antennas with various shapes and dimensions had been designed and analyzed. 5 (five) distinct antennas designed and their gains and return losses had been observed to evaluate the effects of the changes. From the results of these comparisons, the proper antenna type was selected and it was manufactured.Conference Object Naturalness Analysis of the Speech Synthesized by a Tts Card(Ieee, 2016) Tora, Hakan; Uslu, BaranIt is known that the performance of a developed text-to-speech (TTS) synthesis system is assessed by subjective tests. These assessments are usually based on the intelligibility and naturalness of the synthesized speech. In this study, an investigation on relating these subjective test results, thus the naturalness of the synthesized speech, to which acoustic features is accomplished. Consequently the features which will increase the performance while synthesizing the speech are determined. Our work is focused especially on the pitch frequency and energy parameters.Conference Object Citation - WoS: 1Method Proposal for Distinction of Microscope Objectives on Hemocytometer Images(Ieee, 2016) Ozkan, Akin; Isgor, S. Belgin; Sengul, GokhanHemocytometer is a special glass plate apparatus used for cell counting that has straight lines (counting chamber) in certain size. Leveraging this special lam and microscope, a cell concentration on an available cell suspension can be estimated. The automation process of hemocytometer images will assist several research disciplines to improve consistency of results and to reduce human labor. Different objective measurements can be utilized to analyze a cell sample on microscope. These differences affect the detail of image content. Basically, while the objective value is getting increased, image scale and detail level taken from image will increase, yet visible area becomes narrower. Due to this variation, different self-cell counting approaches should be developed for images taken with different objective values. In this paper, using the hemocytometer images gathered from a microscope, a novel approach is introduced for which can estimate objective values of a microscope with machine learning methods automatically. For this purpose, a frequency-based visual feature is proposed which embraces hemocytometer structure well. As a result of the conducted tests, %100 distinction accuracy is achieved with the proposed method.Conference Object Uhf Propagation Measurements in Heavy Industry(Ieee, 2016) Tutuncu, Seyma; Kara, AliEstimating in-factory radio signal propagation characteristics accurately provides robust communication link configuration in these areas. In line with this purpose, this work here provides propagation path loss measurement results carried out in three heavy industrial environments at 315, 434, 870 ve 915 MHz frequency bands.Conference Object Systematic Mapping for Big Data Stream Processing Frameworks(Ieee, 2016) Alayyoub, Mohammed; Yazici, Ali; Karakaya, ZiyaThere has been lots of discussions about the choice of a stream processing framework (SPF) for Big Data. Each of the SPFs has different cutting edge technologies in their steps of processing the data in motion that gives them a better advantage over the others. Even though, the cutting edge technologies used in each stream processing framework might better them, it is still hard to say which framework bests the rest under different scenarios and conditions. in this study, we aim to show trends and differences about several SPFs for Big Data by using the Systematic Mapping (SM) approach. To achieve our objectives, we raise 6 research questions (RQs), in which 91 studies that conducted between 2010 and 2015 were evaluated. We present the trends by classifying the research on SPFs with respect to the proposed RQs which can help researchers to obtain an overview of the field.Conference Object Citation - Scopus: 5A Model Driven Approach To Web-Based Traffic Simulation(Ieee, 2016) Cetinkaya, Deniz; Software EngineeringAs the world population increases the number of vehicles in the traffic increases as well, and so the traffic becomes more complex. Problems in the urban traffic such as traffic congestion, car accidents, parking difficulties, etc. have a large impact on people's lives as well as the environment. Therefore, researchers, policy makers, decision takers and planners use expert tools to find the best solutions for traffic and transportation problems. Traffic modeling and simulation has been used for analyzing, designing, planning and managing urban traffic for many years. Various techniques have been proposed and many tools have been developed by researchers to assist the modeling and simulation activities in the traffic domain for more than half a century. However, improving the existing methods and developing new tools for traffic simulation are gaining importance due to the emerging technologies. Web-based modeling and simulation has been popular in the last decade, and has a great promise in terms of collaborative and distributed simulations. Model driven approaches are employed in the simulation field for a long time and have provided rapid development solutions. In this paper, a model driven Web-based traffic simulation framework is proposed and a prototype implementation is presented.Conference Object A Distributed Smart Pev Charging Algorithm Based on Forecasted Mobility Energy Demand(Ieee, 2016) Kisacikoglu, Mithat C.; Erden, Faith; Erdogan, NuhThis study proposes a new distributed control strategy for the grid integration of plug-in electric vehicles. The proposed strategy consists of two stages: (i) an offline process to determine an aggregated reference charge power level based on mobility estimation and base load profile, and (ii) a real-time operation based on the distributed control approach. The control algorithm manages PEV charge load profiles in order to flatten the residential distribution transformer loading while ensuring the desired state of the charge (SOC) level. The proposed algorithm is tested on real distribution transformer loading data, and compared with heuristic charging scenarios. The numerical results are presented to demonstrate the impact of the proposed algorithm.
