    Statistical analysis of fundamental seismotectonic parameters for future Earthquake occurrences in tunceli province of Turkey

    Öztürk, S.

    An evaluation based on Gutenberg-Richter b-value, fractal dimension Dc-value, completeness magnitude Mc-value, annual probability and recurrence time of earthquakes is carried out for Tunceli province of Turkey. Earthquake catalog covers the years between 21 September 1970 and 30 December 2016, and contains 5462 earthquakes with magnitude equal to and greater than 1.1. Magnitude completeness is estimated as 2.8 and b-value is found as b=0.98+/-0.01. This b-value is smaller than average value of b=1.0 given for Gutenberg-Richter relation. So, this low b-value may be an indicator of stress to build up over time at the beginning of 2017. Dc-value is obtained as 1.63+/-0.04 with 95% confidence limits. This high Dc-value indicates that seismicity in Tunceli and vicinity is more clustered at larger scales or in smaller areas. Annual probability of the earthquakes between 4.5 and 5.5 magnitude levels exhibits a value between 1 and 10. Recurrence time of the earthquakes has a value between 10 and 30 years for magnitude levels between 5.5 and 6.0, and a value between 30 and 100 years for magnitude levels between 6.0 and 6.5. Consequently, this part of Turkey may have an earthquake potential for the possibility of intense earthquake occurrences in the next future.

    Determination of the dynamic characteristics of the faculty building of engineering and natural science with hvsr method and fsr method

    Beker, Y.; Sayıl, N.

    Seismic response characteristics of structures can be estimated by spectral ratios of microtremors measured on structures and their foundation ground surface. The microtremor horizontal-to-vertical-spectral-ratio (HVSR) technique has received great attention from all over the world with its simplicity together with quick information about dynamic characteristics of ground and structures. The HVSR of microtremors gives a good estimation of natural building frequency. In this study, Nakamura (H/V) method and Floor Spectral Ratio Method (FSR) has been applied to microtremor records taken with three component broad band velocity seismometers in seven different locations inside the building (ground floor; east and west side for second, fourth and sixth floor) and one at outside with the aim of determining the dynamic characteristics of Faculty building of Engineering and Natural Science at Gumushane University, in NE Turkey. The average predominant frequency, period and amplification values for the Faculty building are calculated. The ratio of amplitude spectrum of the upper floors to amplitude spectrum of the ground floor for both of horizontal components (East-West, North-South) is determined using FSR Method. The vibration frequency and period is around 4.0 Hz and 0.332 s, respectively. Also, the damping ratio and vulnerability were calculated to the Faculty building.

    K-Ar dating for determining the age of mineralization as alteration product: A case study of antimony mineralization vein type in granitic rocks of Gümüşhane area, Turkey

    Vural, A.

    Is it feasible to use K-Ar dating method in determination of the age of mineralization by utilizing alteration minerals? The purpose of this study was to examine the utility of the K-Ar dating method to accurately determine the age of mineralization. In ideal circumstances, dating of alteration products, such as illite and serisite minerals, gives the age of alteration event, which is indirectly associated with mineralization. In the study site, referred to as Avliyana, antimony mineralization (Gümüşhane, Turkey), stibnite (antimony) mineralizations of hydrothermal vein type were observed in granitic young intrusive rocks and the host rocks. In the study area, alteration was observed in the form of a small amount of weak silicification, argillitization (sericitization and illitization), hematitization, limonitization close to the mineralization and of epidotization and chloritization far from the mineralization. In order to determine the limits of the age of antimony mineralizations of the area, the K-Ar method was used to date illite and serisite minerals, which are alteration products related to mineralization. Two samples containing sericite and illite were collected from Avliyana antimonite mineralization. The alteration origin of these minerals was confirmed by supporting petrographic, XRD and scanning electron microscope studies. These samples were analysed for K-Ar dating.

    Bayram, Bulent; Avsar, Ozgur; Seker, Dursun Zafer; Kayi, Abdullah; Erdogan, Mustafa; Eker, Oktay; Janpaule, Inese; Reis, Hatice Catal

    Coastline changes are increasing rapidly due to both natural and human effects. The expansion of touristic, industrial and culture fishing establishments through coastal areas has brought about uncontrolled and unplanned urbanization. In this study, the coastline in Karasu district of Turkey has been extracted by using Unmanned Aerial Vehicle (UAV) images. For this purpose; 7 cm ground sample distance (GSD) UAV images taken in 2013 by Gatewing-X100 by 40% side and 70% forward overlap was used as post images. Produced ortho images were used as the base map for extraction of the coastline. An object-oriented approach has been applied to capture the shoreline from these ortho images. In the presented study, the eCognition object-oriented fuzzy image processing software has been used. This commercial software has the ability to develop custom tools for image classification in addition to its standard object feature tools. Customized arithmetic features have been used to achieve more accurate shoreline segmentation results. Three main object classes have been created as sea, shoreline buffer and land to extract shoreline. The segmentation results were converted into dxf vector data format. The results were compared with manual digitizing of 55 blind readers. An algorithm has been developed by using Matlab to analyze the differences between object-oriented classification and manual digitizing results. Results were evaluated according to students' gender, age, spent time, used software and courses taken. The root mean square error (RMSE) was calculated as 7.15 m.

    An Effective Database Watermarking Method Based On Histogram of Pairs

    Sahin, Yasin; Ulutas, Guzin; Imamoglu, Mustafa Bilgehan

    Protecting database integrity has become a matter of increasing importance nowadays as accessing information is getting easier. Therefore, database watermarking approach to protect the integrity become an active research area. Most of the existing relational database watermarking techniques embed a generated watermark in the database. Zero watermarking is employed in the proposed technique by storing the watermark generated from the database in another medium independent from the database. In order to make the method robust to column replacement attacks, cell values are split into overlapping pairs and column number is added to pairs. The histogram of pairs is used as the watermark because any change in either a cell value or column replacement would affect the histogram. Experimental results indicate robustness to column replacement attack as well as improved processing time compared to other works reported in the literature.
