Application of cellular neural network (CNN) to the prediction of missing air pollutant data
No full textBayat, Cuma (Arel Author)For air-quality assessments in most major urban centers, air pollutants are monitored using continuous samplers. Sometimes data are not collected due to equipment failure or during equipment calibration. In this paper, we predict daily air pollutant concentrations (PM(10) and SO(2)) from the Yenibosna and Umraniye air pollution measurement stations in Istanbul for times at which pollution data was not recorded. We predicted these pollutant concentrations using the CNN model with meteorological parameters, estimating missing daily pollutant concentrations for two data sets from 2002 to 2003. These data sets had 50 and 20% of data missing. The results of the CNN model predictions are compared with the results of a multi-variate linear regression (LR). Results show that the correlation between predicted and observed data was higher for all pollutants using the CNN model (0.54-0.87). The CNN model predicted SO(2) concentrations better than PM(10) concentrations. Another interesting result is that winter concentrations of all pollutants were predicted better than summer concentrations. Experiments showed that accurate predictions of missing air pollutant concentrations are possible using the new approach contained in the CNN model. We therefore proposed a new approach to model air-pollution monitoring problem using CNN. (C) 2011 Elsevier B.V. All rights reserved
Assessment of particulate matter in the urban atmosphere: size distribution, metal composition and source characterization using principal component analysis
No full text#nofulltext# --- Bayat, Cuma (Arel Author)In this study, the size distribution of airborne particles and related heavy metals Co, Cd, Sn, Cu, Ni, Cr, Pb and V in two urban areas in Istanbul: Yenibosna and Goztepe, were examined. The different inhalable particles were collected by using a cascade impactor in eight size fractions (9 µm) for six months at each station. Samples were collected on glass fiber filters and filters were extracted and analyzed using ICP-MS. Log-normal distributions showed that the particles collected at the Yenibosna site have a smaller size compared to the Goztepe samples and the size distribution of PM was represented the best by the tri-modal. The average total particle concentrations and standard deviations were obtained as 67.7 ± 17.0 µg m-3 and 82.1 ± 21.2 µg m-3, at the Yenibosna and Göztepe sites, respectively. The higher metal rate in fine and medium coarse PM showed that the anthropogenic sources were the most significant pollutant source. Principal component analysis identified five components for PM namely traffic, road dust, coal and fuel oil combustion, and industrial
A new approach to prediction of SO2 and PM10 concentrations in Istanbul, Turkey: Cellular Neural Network (CNN)
No full textBayat, Cuma (Arel Author)This article describes the application of a cellular neural network (CNN) to model air pollutants. In this study, forthcoming daily and hourly values of particulate matter (PM10) and sulphur dioxide (SO2) were predicted. These air pollutant concentrations were measured at four different locations (Yenibosna, Sarachane, Umraniye and Kadikoy) in Istanbul between 2002 and 2003. Eight different meteorological parameters (temperature, wind speed and direction, humidity, pressure, sunshine, cloudiness, rainfall) recorded at Florya and Goztepe meteorological stations were used to model inputs. First, the results of CNN prediction and statistical persistence method (PER) were compared. Then, CNN and PER outputs were correlated with real time values by using statistical performance indices. The indices of agreement (d) for daily mean concentrations were found using CNN and PER prediction models: 0.71-0.80 and 0.71-0.78 for PM10, and 0.81-0.84 and 0.77-0.82 for SO2 in all air quality measurement stations, respectively. From these values, CNN prediction model are concluded to be more accurate than PER, which is used for comparison. In hourly prediction of mean concentrations with CNN, d value is found as 0.78 and 0.92 for PM10 and SO2, respectively. Thus, it was concluded that CNN-based approaches could be promising for air pollutant prediction

The novel "Tyll" by Daniel Kehlmann in the context of postmodern fiction
No full textAvusturyalı-Alman yazar Daniel Kehlmann'ın 2017 yılında yayınlan en son eseri Tyll'in incelendiği bu çalışmada metne bağlı inceleme yöntemi olmak üzere çoğulcu araştırma metoduyla postmodern söylem özelliklerinin analizi amaçlanmakadır. Tyll, Otuz Yıl Savaşı ve Barok dönemden bir hikâyedir. Aynı zamanda eserin başkarakteri olan Tyll, eserde bütün öykülerde yer alan bir figürdür. Fakat eser ünlü hokkabaz hakkında yazılmış bir eser değildir. Kehlmann efsanevi Orta Çağ figürü ünlü hokkabaz Till ya da Thyl Eulenspiegel'i Otuz Yıl Savaşının Almanya'sına yerleştirerek Avrupanın siyasi ve entelektüel topoğrafyasını kararlı bir şekilde şekillendiren bir döneme hareket etmektedir. Bunu yaparken de Barok dönemi bir kahraman için tipik olan Tyll'e benzersiz nitelikler eklemekte ve sanatsal olarak iç içe geçmiş bir dünya canlandırmaktadır. İlk olarak bu çalışmada tez başlığında yer alan Tyll eseri ve yazarı Daniel Kehlmann ile igili bugüne kadar yapılan lisansüstü çalışmalar ile ülkemiz akademisyenlerinin makale ve bildirileri hakkında bilgiler verilmektedir. Daha sonra analizin yürütülmesi için gerekli olan teorik temeller aktarılmakta ve bu çalışma ile ilişkileri sunulmaktadır. Sunulan teoriler daha fazla içeriğe sahip olsalar da, kaynakların kendilerine atıfta bulunularak yalnızca analiz için yararlı olan yönler vurgulanmaktadır. Bu teorik bilgilere yardımcı olması adına Kehlmann'ın konuyla ilgili yaptığı açıklamalar da kullanılmaktadır. Postmodern edebiyat özelliklerine göre incelediğimiz çalışmada yazar Kehlmann ve eseri Tyll hakkında detaylı bir bilgi verildikten sonra çalışma, hangi satırların "üstkurmaca", "metinlerarasılık", "eklektiktizm", "kitsch", "çoğulculuk", "yeni çağ", postmodern gerilim/gizem" ve "postmodern kimlik" özelliklerini yansıttığı göstererek devam etmektedir. Daha sonra Tyll'den alıntılar kullanılarak yapılan tespitler ve analizler, teorik çerçevede ele alınan tezlere dayanarak yorumlanmaktadır. Sadece ilgili bölümler ele alındığından eserin bazı bölümleri analize dâhil edilmemiştir. Son olarak, analizi yapılan postmodern söylem özelliklerinin ve esere yansımasının genel bir değerlendirmesini ve bununla ilgili çıkarımları içeren "Sonuç" bölümü sunulmaktadır.In this study, where Austrian-German writer Daniel Kehlmann's latest work Tyll, which was published in 2017, is analyzed, is aimed to examine postmodern discourse features through textual analysis. Tyll is a story from the Thirty Years War and Baroque era. Tyll is a figure in all stories in the novel, but it is not a novel written about the famous juggler. Kehlmann bring the legendary, famous Medieval figure famous juggler Till or Thyl Eulenspiegel to Germany's Thirty Years War, which is a period that decisively shapes the political and intellectual topography of Europe. In doing so, he adds unique qualities to Tyll, typical of a Barock hero, and portrays an artistically intertwined world. Firstly, information about the novel Tyll and its autor Daniel Kehlmann, and post-graduate studies and articles of Turkey academicians are given. Then, the theoretical foundations required for conducting the analysis are introduced and their relations with this study are presented. Although the theories presented have more content, reference is made to the resources themselves, emphasized only those aspects that are useful for analysis. To help with this theoretical information, Kehlmann's explanations on these topics are also used. The study we examined according to the postmodern literary features, after gived detailed information about the author Kehlmann and his work Tyll, continues by showing, which lines reflect "metafiction", "intertextuality", "eclecticism", "kitsch", "pluralism", "new age", postmodern tension / mystery " and "postmodern identity". Then, the determinations and analyzes using quotes from Tyll are interpreted based on the theses dealt with in the theoretical framework. Some parts of the novel are not included in the analysis since only the relevant sections is handled with. Finally, the "Conclusion" section, which includes a general evaluation of the analyzed postmodern discourse features and its reflection on the work, is presented
Perencanaan Penataan Kawasan Wisata Kampung Batik Bayat Di Desa Jarum Kabupaten Klaten
No full textJarum Village is a village in Bayat sub-district, Klaten district which has the largest potential characteristics of hand-written batik industry craftsmen in Solo Raya, production is spread across other districts such as Yogjakarta and Surakarta. The progress of this needle village is that it has become a tourist village and received a National Level award. Starting from the 1960s, the production of written batik industry experienced a golden age. However, in the 1970s there was a crisis of decline because many batik craftsmen migrated abroad to look for other jobs to fulfill their lives. The batik industry in Bayat was maintained and re-sustained from the initiative proposed by several youths in the 1980s, having moved from its original location from Paseban and Beluk Villages to Jarum Village. In the present or 2024, based on the author's research, the physical condition of the needle tourist village does not yet reflect that it is a tourist village. From the review above, the author is planning to organize the tourist area of the Batik Bayat village in the needle village of Klaten Regency to become an icon of an educational tourism village. Regional planning aims to maintain, preserve and make it easy for tourists to get to know and discover batik crafts. To respond to this, the author conducted research in the form of evaluating existing designs and redesigning the arrangement of the Bayat batik village area. The design methods used are literature research, surveys, interviews, and data analysis carried out using descriptive methods. The research results show that the existing conditions do not meet 3A as a tourist village. Apart from that, the author analyzed the 3A components to achieve success in tourist areas by planning the arrangement of the Bayat batik village area. By planning the arrangement of the village area, it helps local residents develop their potential and improve the community's economy. It is hoped that this can be a recommended attraction for tourists visiting Klaten Regency. Thus, Klaten Regency has the advantage of innovative hand-drawn batik village tourism, education and recreation

No full textNEW OPPORTUNITIES FOR TURKEY WITHIN THE GLOBAL CLIMATE CHANGE REGIME
No full text8th International Scientific Conference on Modern Management of Mine Producing, Geology and Environmental Protection -- JUN 16-20, 2008 -- Sofia, BULGARIAOver the last couple of decades, climate change has emerged to be one of the most complex challenges of the 21(st) century. As a result of the international cooperation achieved over the years, a global climate change regime has been established governed by climate politics. Over the last 50 years, the impacts of climate change have reached measurable dimensions. The fact that the average temperature of the earth's surface that is closer to the atmosphere has risen by 0.6 degrees C over the 20(th) century as well as 10-15% decrease in the glacier dimensions between 1950-2000 have given impetus to scientific research and international cooperation. This paper, after highlighting the major outcomes of the most recent international conference on climate change; the Bali Conference held in December, in Bali, Indonesia; attempts to evaluate Turkey's position within the global climate change regime. Accordingly, first, the critical time period until the end of 2009, emanating from the Bali Action Plan, has been underlined. The importance of conducting negotiations within this time period has been emphasized as a precondition for Turkey to become an active part of the global climate change regime in the post-2012 period with those terms which she can afford to deliver as well as an important complement of her sustainable development policies. In this respect, some alternatives have been proposed with the aim of holding some light on these critical negotiations
