    Consumer Reports (CR) and J.D. Power and Associates (JDP) are two widely-known agencies that gather data on automobile quality and prepare reports on the data gathered that are related to various aspects of automobiles for different models for each manufacturer. This research has two overarching goals: The first is to determine if there are any clear differences in reliability, between the Japanese and U.S. auto-makers. The second is to determine if there is consistency between JDP and CR in the reliability ratings of vehicles. In order to attain these goals, this dissertation starts with the evaluation of these two major sources in terms of the kind of information they present, the way they collect their data, and what they measure. The result of the analysis provides a perspective on the magnitude and value of the information provided by these sources. The first overarching goal of this research is to obtain comparable quantitative information about automobile reliability manufactured by the U.S. Big Three and their Japanese counterparts. The manufacturers surveyed include US-based companies, such as Ford Motors, GM, and Chrysler, and Japanese-based companies, such as Toyota and Honda. An approach to develop a realistic comparison of data related to a given metric for any given automobile type from the two reports is presented. Then the results from the analyses of the actual data for three American manufacturers and two Japanese manufacturers are shown. Finally, regression analysis was used to determine whether the reliability data of American and Japanese manufacturers showed statistically significant trends and gaps. The results of the regression analysis conclude the dissertation --Abstract, page iii

    Copyright © Congress of Balkan Geophysical Society, BGS 2019. All rights reserved.Izmir Gulf is an actively growing shallow marine basin controlled by active faults trending NE, NW, N-S and E- W in the West Anatolian Extensional Province. The bay is topographically divided into an E-W-trending inner bay and a NW-trending outer bay. In the bathymetric maps was the gulf according to the shoreline into three regions divided. These regions are:the eastern (inner) part, the central part (outer part) and the western part Geologicaly is the the inner bay of Izmir an asymmetric graben structure containing upper cretaceous-Palaeocene basement, an older succession of lower to upper Miocene basin fill, overlain with angular unconformity by a younger Plio-Quaternary basin fill. The older succession contain a thick, folded and coal-bearing continental volcano-sedimentary sequence. The younger succession includes the upper Pliocene-Pleistocene Görece formation and Holocene to recent alluvial fan, fan delta to shallow marine deposits.This shallowe marine deposites will be investigated today systematicaly using modern shallowe marine geophysical instruments. This investigations reveals everyday more features of the sea bottom related bathymetry (topographie,), structures on the sea bottom (geothermal site, naturell gas site, gas seeps site, mud volcanouse site, pockmark-pockmark field site and man made object site (wreck site) in the regions of Izmir bay

All Rights Reserved.The Mediterranean Sea is a remnant of the Tethyan ocean basin, which is being consumed as Africa subducted beneath Anatolia. The Isparta Angle (IA) in Beydağları complex, the convex intersection of the Hellenic and Cyprion arcs, is widely recognized as an important tectonic feature and that results in the complex structure passing a particular problem fort he monitoring of seismicity either in the region or over paths that traverse the territory. The geometricaly anomalous Isparta Angle (IA) developed over these contractional features and should be considered within the context of the adjacent subduction systems: The hellenic arc to the West and the Cyprus arc to the east. The Hellenic arc is characterized by a relatively steep, retraiting subduction, wheras the Cyprus arc appear to invalue a more shallowe subduction and anticlockwise rotation of Anatolien block (Turkey) is the cause of extension and deformation in the crust from eastern mediterranean undermarine deep sea structures. They are Antalya Basin,Finike Basin, Rodos Basin and South of them Anaximander Mountain, Piri Reis Mountain, Sırrı Erinç Plateu. The aim of this paper is to discuss the geological location and seismic profiles of Antalya and Finike Basins

    A text linguistic model for intercultural comparisons in academic texts

    No full text
    This article aims to emphasize the importance of intercultural text linguistic comparisons for the production of academic texts. Therefore, a case study has been presented for an intercultural comparison of academic texts. In relation with this aim, a text linguistic model has been submitted for text analysis. An important result of this study is that intercultural comparisons do not only show the cultural differences between languages, but also contribute to the reception and production of academic texts in the native and in foreign language

    Anaximander mountains and deep sea mud volcanoes south of Turkey

    No full text
    Initial stages of continental collision in the eastern Mediterranean Sea dominate the tectonic interaction between Africa and Eurasia, represented by the westward extrusion of the Anatolian microplate. The plate boundary is well defined through the Hellenic Arc to the west and through the Cyprus Arc to the east. The offshore Anaximander Mountains are an important link between the Hellenic and Cyprus arcs. They were formed by southeastward rifting from Turkey in post-Miocene time. Gravity data have shown that the eastern part of the Anaximander Mountains is different from the western part; multibeam mapping seems to confirm that the eastern Anaximander Mountains have affinity with the Florence Rise structure (western Cyprus Arc). Faulting along and across the latter feature is characterized in the seismic data by anastomosing faults and pop-up flower structures. It is likely that progressive adjustment to incipient collision developed into a broad zone of NW-SE transpressive wrenching extending towards south Turkey. In contrast, the western mountains are more directly related to the opening of the Rhodes Basin and the Finike Basin, as transtension may have dominated in southwest Turkey since the Pliocene (A.E. Aksu et al.,2009). The connection with onshore Turkey is still unclear, but could be related to the Fethiye-Burdur Fault Zone that defines the western boundary of the complex Isparta Angle. The Anaximander Mountains and the Isparta Angle form together a tectonic accommodation zone between the active deformation in southwestern Turkey and the Aegean region and the tectonically quieter Cyprus region. (T. A.C. Zitter, 2003) In the last years are in this area on tausends of kilometers sonar; side scan sonar; multibeam and multichannel seismic track lines new bathymetric data collected (Lykousis et al., 2009; A. E. Aksu et al.,2009). Detailed multibeam, sedimentological, and geophysical surveys provide ample new data to confirm that the Anaximander Mountains (Eastern Mediterranean) are an important area for active mud volcanism and gas hydrate formation. Very detailed morphology maps have been made of the known targeted mud volcanoes (Amsterdam, Kazan and Kula), especially the Amsterdam "crater" and the related mud breccia flows. New mud volcanoes identified on the basis of multibeam backscatter intensity were sampled, documented as active and named "Athina" and "Thessaloniki". Gas hydrates were sampled also in Thessaloniki mud volcano, the shallowest (1264 m) among all the active Mediterranean sites, at the boundary of the gas hydrate stability zone. Biostratigraphical analyses of mud breccia clasts indicated that the source of the subsurface sedimentary sequences consists of Late Cretaceous limestones, Paleocene siliciclastic rocks, Eocene biogenic limestones and Miocene mudstones. Rough estimations of the total capacity of the Anaximander mud volcanoes in methane gas are 2.56-6.40 km3. (Lykoisis et al. 2009)
