Book Part Citation - Scopus: 1Online Urban Information Systems(IGI Global, 2008) Yigitcanlar, Tan; Saygin, ÖmürCountless factors affect the inner workings of a city, so in an attempt to gain an understanding of place and making sound decisions, planners need to utilize decision support systems (DSS) or planning support systems (PSS). PSS were originally developed as DSS in academia for experimental purposes, but like many other technologies, they became one of the most innovative technologies in parallel to rapid developments in software engineering as well as developments and advances in networks and hardware. Particularly, in the last decade, the awareness of PSS have been dramatically heightened with the increasing demand for a better, more reliable and furthermore a transparent decision-making process (Klosterman, Siebert, Hoque, Kim, & Parveen, 2003). Urban planning as an act has quite different perspective from the PSS point of view. The unique nature of planning requires that spatial dimension must be considered within the context of PSS. Additionally, the rapid changes in socio-economic structure cannot be easily monitored or controlled without an effective PSS. © 2025 Elsevier B.V., All rights reserved.Book Part Information and Communication Technology for E-Regions(IGI Global, 2008) Velibeyoǧlu, Koray; Yigitcanlar, TanInformation and communication technologies (ICTs) are essential components of the knowledge economy, and have an immense complementary role in innovation, education, knowledge creation, and relations with government, civil society, and business within city regions. The ability to create, distribute, and exploit knowledge has become a major source of competitive advantage, wealth creation, and improvements in the new regional policies. Growing impact of ICTs on the economy and society, rapid application of recent scientific advances in new products and processes, shifting to more knowledge-intensive industry and services, and rising skill requirements have become crucial concepts for urban and regional competitiveness. Therefore, harnessing ICTs for knowledge-based urban development (KBUD) has a significant impact on urban and regional growth (Yigitcanlar, 2005). In this sense, e-region is a novel concept utilizing ICTs for regional development. Since the Helsinki European Council announced Turkey as a candidate for European Union (EU) membership in 1999, the candidacy has accelerated the speed of regional policy enhancements and adoption of the European regional policy standards. These enhancements and adoption include the generation of a new regional spatial division, NUTS-II statistical regions; a new legislation on the establishment of regional development agencies (RDAs); and new orientations in the field of high education, science, and technology within the framework of the EU’s Lisbon Strategy and the Bologna Process. The European standards posed an ambitious new agenda in the development and application of contemporary regional policy in Turkey (Bilen, 2005). In this sense, novel regional policies in Turkey necessarily endeavor to include information society objectives through efficient use of new technologies such as ICTs. Such a development seeks to be based on tangible assets of the region (Friedmann, 2006) as well as the best practices deriving from grounding initiatives on urban and local levels. These assets provide the foundation of an e-region that harnesses regional development in an information society context. With successful implementations, the Marmara region’s local governments in Turkey are setting the benchmark for the country in the implementation of spatial information systems and e-governance, and moving toward an e-region. Therefore, this article aims to shed light on organizational and regional realities of recent practices of ICT applications and their supply instruments based on evidence from selected local government organizations in the Marmara region. This article also exemplifies challenges and opportunities of the region in moving toward an e-region and provides a concise review of different ICT applications and strategies in a broader urban and regional context. The article is organized in three parts. The following section scrutinizes the e-region framework and the role of ICTs in regional development. Then, Marmara’s opportunities and challenges in moving toward an e-region are discussed in the context of ICT applications and their supply instruments based on public-sector projects, policies, and initiatives. Subsequently, the last section discusses conclusions and prospective research. © 2025 Elsevier B.V., All rights reserved.Book Part Citation - Scopus: 1Strengthening the Knowledge-Base of Cities Through ICT Strategies(IGI Global, 2008) Yigitcanlar, Tan; Velibeyoǧlu, KorayThe chapter sets out to explain the KBD processes and challenges and opportunities in information acceptance and use in urban policy making.

The controller is developed under the assumption that the user and environmental input forces arc unmeasurable. Lyapunov-based stability analysis is used to prove that the proposed controller yields asymptotic tracking results and ensures the coordination of the master and slave systems while satisfying a sub-task objective. Numerical simulation results are presented to illustrate the effectiveness of the proposed controller.Book Part Factors Affecting the Learning Process of Professionals in Architectural Design Firms(CRC Press, 2009) Ozturk-Barlak,G.B.; Arditi,D.; Gunaydin,H.M.; Kale,S.; Yitmen,I.Learning is considered to be a sophisticated process and a source of competitiveꀊadvantage. Learning is essential in project-based environments. The one-of-a-kind structure of the operations of architectural design firms triggers special learning needs and requires a continuous learning activity. Learning is considered to improve an architectural design firm’s efficiency by recognizing the role of individuals in enhancing the firm’s objectives. However, theoretical research on individual professionals’ learning process in the architectural design is rather uncommon. The process of individual learning is composed of (1) data acquisition (2) assessment of the acquired information and (3) implementation of the knowledge gained in a group setting. Ten factors were identified to assess the effectiveness of the learning processes of professionals. This study is the first study in the field of architecture that presents a conceptual model about the factors that affect the effectiveness of the learning process of professionals. © 2010 Taylor and Francis Group, London, UK.Article Citation - Scopus: 2Film-Formation Property of Vinylidene Chloride-Methyl Methacrylate Copolymer Latex. Ii. Effect of Latex Storage Temperature(2002) Cai,W.D.; Ramesh,N.; Tihminlioglu,F.; Danner,R.P.; Duda,J.L.; Dhaan,A.Changes in the minimum film-formation temperature (MFFT) of 91:9 wt% vinylidene chloride (VDC)-methyl methacrylate (MMA) latex prepared by the seeded batch process during storage at 5, 20, and 40°C were investigated. MFFT of the latex rose the fastest at 20°C. Infrared absorption of fresh and stored latexes and wide-angle X-ray diffraction of powder polymers obtained by lyophilization of fresh and stored latexes indicated a much greater increase in polymer crystallinity during latex storage at 20°C than at 5 and 40°C. Observed increases in MFFT during latex storage correlated with increases in polymer crystallinity. Infrared absorption of polymer stored at 5-60°C in the dry state, such as lyophilized polymer and coating film, indicated that a polymer crystallinity increase was greater during storage at higher temperatures. These results showed that crystallization behavior of 91:9 wt% VDC-MMA copolymer latex differed from that of VDC-MMA copolymer in the dry state.Article Citation - Scopus: 33Modified Wheat Starches Used as Stabilizers in Set-Style Yogurt(2001) ÓZKAN,M.; YemenicioǦLU,A.; ÇITAK,B.; CemeroǦLU,B.Yogurt was formulated with gelatin; native wheat starch (NWS); and modified wheat starches (MWS) (acetylated cross-linked, hydroxypropylated, or hydroxypropylated cross-linked). Yogurt samples were evaluated for chemical (fat, total solids, pH, titratable acidity); microbiological (yeasts/molds and lactic acid bacteria); and physical (rheological, textural, color, syneresis) properties during 60 days of refrigerated storage. Yogurt formulated with NWS exhibited a significantly greater storage modulus (G') and firmness compared with yogurts prepared with MWS. Minimal syneresis was measured in all yogurt samples. The titratable acidity of yogurt samples increased and pH decreased during storage. Yeasts/molds were not detected while lactic acid bacteria counts decreased ∼ 1 log CFU/g by day 60 in all yogurt samples. This study showed that the characteristics of yogurt formulated with NWS and gelatin were similar, so NWS may be used as an alternative stabilizer. The MWS stabilized yogurts were stable but had different consistencies than gelatin- and NWS-stabilized yogurts.Article Citation - Scopus: 60Distribution of Elements in Honeys and Effect of a Thermoelectric Power Plant on the Element Contents(1998) Üren,A.; Şerifoglu,A.; Sarikahya,Y.Lead, cadmium, iron, copper, zinc, manganese, calcium, magnesium and potassium contents of Turkish honeys were investigated. Most of the elements were more abundant in honeydew honeys than in flower honeys. But calcium content of honeydew honeys was smaller than in flower honeys. Considerable temporal fluctuation of elements was observed in honeydew honeys produced in the same area and from the same hives during autumn 1992, 1993 and 1994. Element contents of Turkish honeys showed high coefficients of variation, and the coefficients of variation decreased with increasing amounts of total minerals in honeys. The thermoelectric power plant which was 15-18 km away from the hives did not cause any pollution in honeys. Turkish honeys did not show any contamination of lead, cadmium, iron or zinc, and amounts of these elements were found well below the permitted limits.Article Citation - Scopus: 2Mısır, Etrüsk, Roma: Piranesi ve Bir On Sekizinci Yüzyıl Tartışması(Orta Doğu Teknik Üniversitesi, 2008) Ek, Fatma İpek; Şengel, DenizOne crucial debate that resonated in eighteenth-century Europe concerned the origins of European architecture whose effects continue to inform present-day notions of the same. Numerous important eighteenth-century works were produced in the context of emergence of the discipline of architectural history. In this architectural, historical, and archaeological framework, Venetian architect and scholar Giovanni Battista Piranesi (1720- 1778) played an important role by his visual and literary works as well as original approach to history. Piranesi developed a history of architecture that was not based on the East/West division and the separation of continents. In opposition to writers like Winckelmann who rooted the origin of Roman architecture in the Greek, he claimed that Roman architecture derived from the Etruscan which found its roots in Egypt. Discussion of roots depended on the eighteenth century on aesthetical theory interpreting Grecian architecture as ‘beautiful’ and Roman -thus Egyptian- as ‘sublime’. It was in this lively intellectual environment that Piranesi searched the origins of Roman -and thus the whole Europeanarchitecture. His works were, however, misinterpreted as being Orientalist by contemporary scholars following Said.
