Today, preserving architectural heritage is imposed as an obligation, regardless of the type of heritage. Heritage values are irreplaceable and priceless category of the remains of the human activities during the past, at the same time they are a category that seeks for a well prepared preservation program. Regarding a cultural heritage preservation program developed in Bosnia and Herzegovina, it is obvious that much more must be done to preserve all traces of history as well as to manage and understand the heritage in a broader context. The aim of this paper is to emphasize the importance of including different types of properties and urban areas, such as small scale towns, into heritage preservation and development programs. Settlement and heritage assets are subject to change in the future, but contemporary changes could be used as a driver for the development of a wide area and as a key resource for future development. In order to recognize and distinguish the geographical setting of the Bosna River valley as a whole comprised of serial properties, two case studies, namely Tesanj and Vranduk towns settled along the Bosna River are described, focusing on the values as well as development challenges associated with small scale towns in Bosnia and Herzegovina. Relationship between the natural and built heritage of the selected sites acknowledged by its uniqueness, authenticity and integrity could be accomplished through a HUL (Historic Urban Landscape) approach. In this paper, all necessary steps of an integrated management plan are briefly described for the proposed serial of properties, recognizing serial of properties as the only possible sustainable category for the heritage sites along the Bosna River.

In recent decades, according to Intergovernmental Panel on Climate Change reports, the impact of climate change on hydro-meteorological events has increased substantially. This point is obvious in many rainfall-runoff time series as a negative or positive trend. In this paper, first of all such trend possibilities are searched graphically according to Şen's 1:1 (45°) straight-line method, which has been proposed instead of the classical methods including Mann-Kendall, Spearman's rho and linear regression approaches. Additionally, these trends are quantified by using frequency-intensity-duration (FID) curves, instead of intensity-duration-frequency (IDF) curves obtained from a set of single storm rainfall records. The FID curves provide practical, easy and clear representation of rainfall intensity variation through fitted exponential curves with coefficient of determination that is almost equal to 1 (R2≈1). FID curves are drawn on semilogarithmic paper with rainfall intensity estimations from the convenient Gamma probability distribution functions (PDFs) or cumulative distribution functions (CDFs). In this study 46-year rainfall records are used from Florya station, which is located in Istanbul, Turkey. The comparisons generally indicated that a negative trend is valid at this station, and accordingly, representative FID curves are obtained on ordinary and semilogarithmic papers for this station. © 2016 The Chartered Institution of Water and Environmental Management (CIWEM) and John Wiley & Sons Ltd.

May 2013 saw Istanbul witness a massive public demonstration. The incident began on 28 May when a small group of environmental activists tried to save Gezi Park, one of the most iconic green spaces in the Taksim district of central Istanbul. The park dates back to the 1940s and is well-known as public promenade. The modest demonstration was triggered by a government decision to reconstruct a former Ottoman Artillery Barracks. Within a few days, it developed into a violent uprising on an unprecedented scale lasting almost an entire month. Crowds not only gathered in Istanbul but also in many other Turkish cities such as the capital, Ankara. International media broadcast the protests live from Taksim Square turning the Gezi Park protest into an international phenomenon. Today the Park has become a reference point in Turkish politics where almost every issue is linked to the 'spirit of Gezi'. It made a modest protest over an inner city promenade into a vivid symbol of political opposition. This paper will analyse historically the Taksim Square project and the ideological conflicts it evoked in Turkish society. © 2014 Vilnius Gediminas Technical University (VGTU) Press Technika.

Solar irradiation calculations depend on atmospheric variations and sunshine duration record interval. Generally, it is calculated by using the classical Angström-Prescott equation, which provides a linear relationship between the solar irradiation and sunshine duration. Also few 2nd and 3rd degree solar radiation and sunshine duration models are proposed by different authors. Natural events do not have temporal and spatial independent structures. In this paper, three solar irradiation models are used for solar radiation examination in three of the southern cities, Adana, Antakya and Silifke in Turkey. One of these models are proposed in this work as dependency model and this is compared with the Angström-Prescott model and fuzzy logic ANFIS model. The comparison illustrates that dependency model is superior over other approaches. © 2014 Elsevier Ltd. Source

In this study, a computer-aided detection (CAD) system was developed for the detection of lung nodules in computed tomography images. The CAD system consists of four phases, including two-dimensional and three-dimensional preprocessing phases. In the feature extraction phase, four different groups of features are extracted from volume of interests: morphological features, statistical and histogram features, statistical and histogram features of outer surface, and texture features of outer surface. The support vector machine algorithm is optimized using particle swarm optimization for classification. The CAD system provides 97.37% sensitivity, 86.38% selectivity, 88.97% accuracy and 2.7 false positive per scan using three groups of classification features. After the inclusion of outer surface texture features, classification results of the CAD system reaches 98.03% sensitivity, 87.71% selectivity, 90.12% accuracy and 2.45 false positive per scan. Experimental results demonstrate that outer surface texture features of nodule candidates are useful to increase sensitivity and decrease the number of false positives in the detection of lung nodules in computed tomography images.
