Application of Object Based Image Classification Using Orthophotos: A Case Study of the Van-Erci? Earthquake
Asl? Sabuncu, Filiz Sunar
Dogal Afetler ve Cevre Dergisi , 2017, DOI: 10.21324/dacd.271091
Abstract: Earthquakes are the most destructive natural disasters, causing massive loss of life, infrastructure damages and serious financial losses. Earthquake-induced building damage detection is a very important step after earthquakes since such buildings pose a risk for cities. The recent advances in digital photogrammetry/remote sensing technology and satellite sensor/camera systems have inspired to emerge new and different research areas and applications. With the development of digital camera technology since 1950's, it has become possible to produce orthophotos with high spatial resolution and positional accuracy. These orthophotos are used successfully in the extraction of the details and the thematic classification. Depending on the high spatial image resolutions, the use of object-based approach has gained importance and has become widespread rather than the traditional pixel-based approach in the thematic classification. The town of Erci? in Van province, situated in the eastern part of Turkey, was selected for the study. In this region, an earthquake with moment magnitude (Mw) of 7.2 was occurred at 10:41 UTC (13:41 local time) on October 23th, 2011. In this study, the orthophotos produced from the aerial photographs taken one day after the earthquake by the General Command of Mapping for the purpose of damage detection. In the post-earthquake ortophotos, 2 different types of sites were selected as the study areas. As an initial step, segmentation process was carried out by selecting the most suitable parameters for the classification of both homogenous and heterogeneous areas. In the segmentation phase, the multi-resolution algorithm was utilized. After doing different trials, the most suitable shape factor and compactness values were considered. In the next step, two different classification approaches, namely “supervised” and “unsupervised”, used within the object based image classification were applied and their classification accuracies were compared.
Scientific data on selenium status in Turkey  [PDF]

Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.52011
Abstract:

This review provides a summary of the available scientific data on selenium status in Turkey. The first reports regarding selenium status in Turkey appeared in the 1990s. Since then, much attention has been paid to selenium content in soil, cereal crops and a variety of other foodstuffs including corn, garlic, mushrooms, fresh and canned fish, meat and meat products, milk and dairy products, spice and condiment plants and honey. Previous reports by Foster and Summer (1997), Aras et al. (2001) and H?ncal (2007) reported daily selenium intake in Turkey to be 30 μg/day, 20-53 μg/day and 30-40 μg/day, respectively. However, these reports are based on limited local data and cannot be generalized for the entire country. As a result, there is still a need for further research in all seven regions and 81 provinces of the country to measure selenium content of soil, food, water and animal feed in order to determine the average daily selenium intake of animals and humans in Turkey.

Klasik Sosyolojinin arkiyat Kaynaklar : Marx ve Weber’in Kar la t rmal Bir ncelemesi (Orientalist Sources of Classical Sociology: A Comparative Analysis of Marx and Weber)
Lütfi Sunar
?nsan & Toplum Dergisi , 2011, DOI: http://dx.doi.org/10.12658/human.society.1.2.m0041
Abstract: Sociology emerged as a comparative science, which basically tries to find out the differences between societies. Hence, it is important to make comparisons with Oriental societies that may serve as a historical model and situate the forms of modern society with regard to them. In this process, sociology has provided new explanations for European societies through working on the information gathered by orientalists. Therefore, the development and transformation of orientalism have also led to the transformation of sociology. This transformation can clearly be seen through a comparative examination of the approaches, analysis, and sources of Marx and Weber, who supposed to represent opposite poles in sociology. In the mid-19th century while orientalism was at the developmental stage, Marx made broad generalization with limited analysis. When oriental studies became specialized and diverse in the early 20th century, Weber made more extensive comparisons supported by detailed analysis. Despite the epistemological and political differences between Marx and Weber, they were of the same mind in their interpretations of modern society through Oriental societies and their unquestioning use of orientalist sources.
WEBER’S ECONOMIC SOCIOLOGY: ECONOMIC WELTANSCHAUUNG AS A KEY TO UNDERSTAND THE CIVILISATION - WEBER’IN IKTISAT SOSYOLOJISI: UYGARLI I ANLAMANIN ANAHTARI OLARAK IKTISADI ZIHNIYET

Abstract: Weber has an important place in the making of sociology an empirical science. He is also known as the founder of many sub-fields of sociology, including economic sociology. Weber’s sociology aims to explain modernity around rationalization by positioning it in a historical developmental context. To explain modernity Weber had a broad sociological base in his later studies although he had a narrower historical perspective in his earlier studies. In this context his economic sociology has an expanding vision to construct the development of modernity. As a result of a double break in 1904 and 1909, his scope trans- formed toward a world-historical level with his studies on the economic ethics of world religions. He tried to explain the development of modernity with the development of the capitalist spirit, which means rationalization of the world. In this way, he wanted to reach a universal outlook of modernity. So, one may state that at the heart of Weber’s economic sociology lies an analysis of economic mentality. As a result, his economic sociology may be explained as the master key to enable understanding of Weber’s social theory. zet ktisat sosyolojisi de dahil sosyolojinin pek ok alt al ma alan n n kurucusu olarak zikredilen Weber’in sosyolojinin ampirik bir bilim olmas nda nemli bir yeri vard r.

Eurasian Journal of Physics and Chemistry Education , 2011,
Abstract: Being citizens of the near future, students will have to make decisions requiring an understanding of theinteraction of science and technology and its interface with society. Science-Technology-Society (STS)education has been identified with meeting this goal, but putting theory into practice has always been difficult.Since pre-service science teachers will be the implementers of new reform movements regarding STS issuesduring their professions, their views on STS issues are crucial. This study aims to explore Turkish pre-servicescience teachers’ views (n = 78) on STS issues. Data were collected through an adopted version of “Views onScience–Technology–Society (VOSTS)” instrument. Analysis of data revealed that definition of science is notvery explicit among pre-service science teachers whereas most of the participants viewed technology as theapplication of science. Majority of the pre-service teachers agreed that the scientific knowledge is tentative butthey failed to differentiate between hypotheses, laws, and theories.

TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i1.667
Abstract: Shadows are elegant to create a realistic scene in virtual environments variety type of shadow techniques encourage us to prepare an overview on all base shadow techniques. Non real-time and real-time techniques are big subdivision of shadow generation. In non real-time techniques ray tracing, ray casting and radiosity are well known and are described deeply. Radiosity is implemented to create very realistic shadow on non real-time scene. Although traditional radiosity algorithm is difficult to implement, we have proposed a simple one. The proposed pseudo code is easier to understand and implement. Ray tracing is used to prevent of collision of movement objects. Projection shadow, shadow volume and shadow mapping are used to create real-time shadow in virtual environments. We have used projection shadow for some objects are static and have shadow on flat surface. Shadow volume is used to create accurate shadow with sharp outline. Shadow mapping that is the base of most recently techniques is reconstructed. The reconstruct algorithm gives some new idea to propose another algorithm based on shadow mapping.
SHADOW MAPPING OR SHADOW VOLUME?
Hoshang Kolivand,Mohd Shahrizal Sunar
International Journal of New Computer Architectures and their Applications , 2011,
Abstract: In this paper two techniques of shadow generation are described. Volume shadow is geometric base but shadow mapping is image base. Silhouette detection is a most expensive step to create volume shadow. Two algorithms to recognize silhouette are introduced. Stencil buffer and Z- buffer are two other tools for creating shadow by volume shadow technique. Both algorithms are implemented in virtual environment with moveable light source. Triangular method and the Visible-non visible method are introduced. The recent traditional silhouette detection and implementation techniques used in volume shadow algorithm are improved. With introduce flowchart of both algorithms, the last volume shadow algorithm using stencil buffer is rewritten. A very simple algorithm to create volume shadow is proposed. The last shadow mapping algorithm is rewritten. These techniques are poised to bring realism into commercial games. It may be use in virtual reality applications.
