An example of secondary fault activity along the North Anatolian Fault on the NE Marmara Sea Shelf, NW Turkey

Seismic data on the NE Marmara Sea Shelf indicate that a NNE-SSW-oriented buried basin and ridge system exist on the sub-marine extension of the Paleozoic Rocks delimited by the northern segment of the North Anatolian Fault (NS-NAF), while seismic and multi-beam bathymetric data imply that four NW-SE-oriented strike-slip faults also exist on the shelf area. Seismic data indicate that NW-SE-oriented strike-slip faults are the youngest structures that dissect the basin-ridge system. One of the NW-SE-oriented faults (F1) is aligned with a rupture of the North Anatolian Fault (NAF) cutting the northern slope of the Cinarcik Basin. This observation indicates that these faults have similar characteristics with the NS-NAF along the Marmara Sea. Therefore, they may have a secondary relation to the NAF since the principle deformation zone of the NAF follows the Marmara Trough in that region. The seismic energy recorded on these secondary faults is much less than that on the NAF in the Marmara Sea. These faults may, however, produce a large earthquake in the long term

Imaging of subsurface lineaments in the southwestern part of the Thrace Basin from gravity data

Linear anomalies, as an indicator of the structural features of some geological bodies, are very important for the interpretation of gravity and magnetic data. In this study, an image processing technique known as the Hough transform (HT) algorithm is described for determining invisible boundaries and extensions in gravity anomaly maps. The Hough function implements the Hough transform used to extract straight lines or circles within two-dimensional potential field images. It is defined as image and Hough space. In the Hough domain, this function transforms each nonzero point in the parameter domain to a sinusoid. In the image space, each point in the Hough space is transformed to a straight line or circle. Lineaments are depicted from these straight lines which are transformed in the image domain. An application of the Hough transform to the Bouguer anomaly map of the southwestern part of the Thrace Basin, NW Turkey, shows the effectiveness of the proposed approach. Based on geological data and gravity data, the structural features in the southwestern part of the Thrace Basin are investigated by applying the proposed approach and the Blakely and Simpson method. Lineaments identified by these approaches are generally in good accordance with previously-mapped surface faults

Dünyada kalite kontrol ve toplam kalite kontrol uygulamaları (Bölüm I)

A quality phenomenon has quite an old history. Quality control methods had been developed to be able to reach to the targets and aims related with quality. It is possible to design, develop and produce quality products and at the same time to set up an production system which meets the requirements and enables to produce products and services economically by using quality control methods. Quality control which was described in the past as the classification of good and bad is now appeared to be total quality management with a more exclusive meaning. Total quality management covers not only the production stages, but also all the stages that the product follows from the production to the customer. It is the common target of all the countries to reach the high quality level. However, the path that the countries follow to reach this target might differ due to the differences in some conditions like social, cultural, political and economical conditions etc.Kalite kavramının tarihi çok eskilere dayanmaktadır. Kaliteyle ilgili hedef ve amaçlara ulaşabilmek için kalite kontrol yöntemleri geliştirilmiştir. Kalite kontrol yöntemleri sayesinde kaliteli ürünü geliştirmek, tasarımını yapmak, üretmek ve aynı zamanda da ürün veya hizmetleri ekonomik bir yoldan üreten ve gereksinimlere yanıt veren bir üretim sistemini kurmaya yardımcı olmak mümkündür. Önceleri iyi-kötü tasnifi şeklinde tanımlanan kalite kontrol, günümüzde daha geniş bir anlam içeren toplam kalite yönetimi olarak karşımıza çıkmaktadır. Toplam kalite yönetimi sadece üretim basamaklarını değil, ürünün üretimden müşteriye ulaşıncaya kadar ki tüm basamakları kapsamaktadır. Yüksek kaliteye ulaşabilmek, tüm ülkelerin ortak hedefidir. Ancak ülkelerin bu hedefe ulaşmak için izledikleri yollar, sosyal, kültürel, siyasi, ekonomik vb. koşullarına bağlı olarak farklılıklar gösterebilmektedir
