Economic assessment of Balçova-Narlıdere Geothermal District Heating Systems

Thesis (Master)--Izmir Institute of Technology, Mechanical Engineering, Izmir, 2003Includes bibliographical references (leaves: 122-125)Text in English; Abstract: Turkish and Englishxvi, 179 leavesDevelopment of a geothermal district heating system covers full range of activities from the determination of geothermal reservoir to the delivery of geothermal energy successfully. Economic assessments are come true in the early stages of geothermal developments. The goal of this thesis is to realize a detailed economic assessment for Balçova-Narlıdere Geothermal District Heating System (GDHS) which is one of the largest district heating systems in Turkey with its current heating capacity of 50 MWth. Tasks in geothermal district heating investments are looked over at the beginning to make a correct economic evaluation and make future development in this geothermal field easy under the discipline of project management. Internal rate of return method which is commonly used financial tool to find the profitability of investments is applied to this investment. The economic analysis begin with the calculation of end of 2002 values of capital investment costs, revenues and operating costs since the existence of past cash flows. Future operating costs are determined according to the yearly expenditures realized in 2002. Future revenues are determined in accordance with the capacity of current heating system and energy utilization prices valid in 2002-2003 heating season. If the sustainability of a resource is considered in the design, the prospective geothermal district heating system could be operated in a long period. However, long-term period projects contain economic uncertainties for the future cash flows. The overall life of Balçova-Narlıdere GDHS is considered as 20 years after year 2001 and uncertainties are considered in this study. Calculations are realized according to various scenarios in which operating costs are constant throughout 20 years. To determine these scenarios, operating costs in 2002 which reflects the current expenditures are either decreased or increased by some percentages. In addition, 60 different pricing plans have been taken into consideration in these scenarios to demonstrate the effects of energy utilization prices on the profitability of investment. The continuity of current price policy for Balçova-Narlıdere GDHS is discussed and energy utilization prices per 100 m2 are suggested for these scenarios. On the other hand, taxes paid to government in Balçova-Narlıdere GDHS investment are investigated to show the benefits of geothermal investments from the viewpoint of government. Because of the development in production of some equipment like heat exchangers, pipes and changing in marketing strategy, the costs of these equipment are reduced. At the end, internal rate of return method is repeated for the current cost of the investment. The energy utilization prices for 13 different scenarios are found for this situation and results are compared with the prices determined to meet the real cost of the investment

New soluble methylendioxy-phenoxy-substituted zinc phthalocyanine derivatives : synthesis, photophysical and photochemical studies

The syntheses of new three phthalonitriles (1, 2 and 3), together with photophysical and photochemical properties of the resulting peripherally and non-peripherally tetrakis- and octakis 3,4-(methylendioxy)-phenoxy-substituted zinc phthalocyanines (4, 5 and 6) are described for the first time. Complexes 4, 5 and 6 have been synthesized and characterized by elemental analysis, IR, 1H NMR spectroscopy, electronic spectroscopy and mass spectra. Complexes 4, 5 and 6 have good solubility in organic solvents such as CHCl3, DCM, DMSO, DMF, THF and toluene and are mainly not aggregated (except for complex 6 in DMSO) within a wide concentration range. General trends are described for singlet oxygen, photodegradation, fluorescence quantum yields, triplet quantum yields and triplet life times of these complexes in DMSO and toluene. Complex 4 has higher singlet oxygen quantum yields, fluorescence quantum yields, triplet quantum yields and triplet life times than complexes 5 and 6. The effect of the solvents on the photophysical and photochemical parameters of the zinc(II) phthalocyanines (4, 5 and 6) are also reported

21. YÜZYILDA DEMOKRASİ VE EKONOMİK BÜYÜME İLİŞKİSİ: BİR LİTERATÜR İNCELEMESİ

Demokrasi ve ekonomik performans arasındaki ilişkiler sosyal bilimciler özellikle de ekonomistleri son birkaç yüzyıldır ilgilendiren konulardandır. Ancak son dönemlerde özellikle Orta Doğu’da yaşanan demokratikleşme hareketleri, demokrasi ile ekonomik büyüme arasındaki ilişkinin yeniden gündeme gelmesine neden olmuştur. Bu çalışma ile demokrasi ile gelişme-büyüme arasındaki ilişkiyi inceleyen farklı görüşleri sunarak, iki kavram arasındaki ilişkinin daha belirgin hale getirilmesine katkı sağlamak ve özellikle ampirik çalışmalar ışığında 21. yüzyılda bu ilişkinin nasıl olduğunu (varlığı/yokluğu, yönü, derecesi) irdelemek amaçlanmıştır. Yapılan kuramsal ve ampirik değerlendirmede, genel anlamıyla ekonomik büyüme açısından demokratik kurumların daha elverişli (olumlu) olduğu söylenebilir. Bu sonuç, demokrasi ile ekonomik büyüme arasında pozitif ilişki olduğunu ifade eden Bağdaşma Yaklaşımını desteklemektedir. Türkiye’de demokrasi-ekonomik büyüme ilişkisini araştıran az sayıda çalışma incelendiğinde, uluslararası literatürdeki her üç görüşe uygun sonuçların elde edildiği görülmüştür

Scene text dataset in Turkish

25th Signal Processing and Communications Applications Conference, SIU 2017; Antalya; Turkey; 15 May 2017 through 18 May 2017Manzara metni tespit etme ve tanıma gerçek dünya imgelerinden anlamlı içerik çıkarmada ve bu imgelerden olu-şan büyük veri kümelerinde aranan metni bulup getirmede büyük kolaylık sağladığından araştırmacılardan artan bir ilgi görmektedir. Buna rağmen, bu alanda yaygın olarak kullanılan imge kümelerinin büyük kısmı İngilizce metinler içerdiklerinden yapılan çalışmalar tek dil ile kısıtlı kalmıştır. Buradan yola çıkarak, geliştirilen manzara metni tespit etme ve tanıma teknolojilerinin Türkçe metinlere uygulanması, performanslarının analiz edilmesi ve Türkçe’ye özgün algoritmaların geliştirilmesi amacıyla literatürde ilk kez bir Türkçe manzara metni veri kümesi oluşturulmuştur. Bu bildiride, kısaca STRIT (Scene Text Recognition In Turkish) olarak adlandırılan veri kümesinin içeriği anlatılmaktadır. Buna ek olarak, Türkçe manzara tespiti ve tanınması için iki taban çizgisi yöntemi denenmekte ve ön sonuçlar takdim edilmektedir.Scene text localization and recognition keeps attracting an increasing interest from researchers due to its valuable advantage in extracting content from real world images and in image retrieval via text search. Nevertheless, due to the fact that the majority of the image datasets that are commonly used in this field is comprised of text in English, the related studies have mostly been limited to a single language. On that account, in order to apply the technologies developed for scene text detection and recognition to Turkish scene text, analyze their performances and to develop Turkish language specific algorithms, a Turkish scene text database is collected for the first time in the literature. In this paper, the contents of this database, shortly called STRIT (Scene Text Recognition In Turkish), are detailed. Additionally, two baseline methods are tested to detect and recognize scene text in Turkish and the preliminary results are presented.TUBITAK (BIDEB-114C025

What Makes Consumers Recall Banner Ads in Mobile Applications

The uses of mobile advertisements are increasing their popularity across the world. Companies can gather information about the mobile users based on their locations, lifestyle, and preferences via GPS, cookies and browsing history and embed highly personalized banner ads in mobile applications. However, in the literature there is hardly any work on the effectiveness of these highly personalized in-app banner ads. The aim of the study is to reveal which factors affect the effectiveness of in-app banner ads. An experimental study was designed and 209 subjects participated. The results of Ordinal Logistic Regression indicated that prior brand attitude and attitude towards application have a positive effect, while brand engagement with self-concept has a negative effect on the recall of in-app banner ads. Moreover, in-app banner ads are recalled more when they are located in landscape applications and positioned at the top part of the screen. This research provides some implications for future studies and practitioners

Consequences of influencer-created content on influencers’ authenticity in the beauty and personal care industry

One challenge in creating a personal brand is convincing consumers that it is authentic. Brands perceived to be inauthentic will have difficulty engaging with consumers; thus, the brand may not be long-lasting. This is also important for influencers, as they are a type of personal brand. Therefore, it is essential to consider the authenticity that is necessary for influencers when creating their brands. This study adapts the dimensions of advertising content value, and it examines the direct and indirect effects on influencer authenticity and followers’ trust, attitudes, and purchase intentions. The study reached out to 445 social media users interested in beauty and personal care products. The results indicate that the perceived entertainment and perceived informativeness of the influencer’s post content have a significant positive effect on influencer authenticity. Moreover, the results also show that influencer authenticity plays an important role in trust in and attitude toward branded posts. Finally, trust in and attitude toward branded posts lead to purchase intention.</p
