“…The second workshop aimed to develop some features of the German (AzB) method by adapting it to ECAC Doc 29 (3rd Edition). In the discussions, it was accepted that aircraft noise is more specific than other industrial, train and road noises (Licitra, 2012).…”

“…National database such as ICAO ANP was developed to fulfill the requirements of ECAC Doc 29 and accompany Azb 2008. Here, one of the important requirements of the methodology was that it can be used under Directive 2002/30/EC, another was that the CNOSSOS-EU method should also be harmonized with the ICAO methods, as European Union Aviation Safety Agency (EASA) will use the CNOSSOS-EU methodology for regulatory impact assessment in Europe (Licitra, 2012).…”

Purpose In this context, this study aims to obtain information about the noise levels emitted to the environment by modeling the noise map of Dalaman Airport and correlating these noise values according to the Environmental Noise Directive (END) and World Health Organization (WHO) limits. Design/methodology/approach Dalaman Airport Aeronautical Information Publication and 2022 flight data from the airport were analyzed. The noise levels exposed to schools and health institutions were determined using the Cnossos–Eu calculation method. Findings Maximum noise levels were obtained as Lden 92.29 dB(A), Lday 85.24 dB(A), Levening 89.00 dB(A) and Lnight 85.23 dB(A) according to the noise indicators. Limit values recommended by the END and WHO according to noise indicator types and measurement results were correlated and evaluated. Originality/value In the noise modeling of Dalaman Airport, there has previously been no evaluation of the noise limits recommended according to END or WHO in the literature.

“…Gürültü etkilerini ölçmek ve görselleştirmek için genişletilmiş bir konumsal veri tabanına ve hesaplama, sorgulama, renklendirme yeteneğine sahip yöntemlere ihtiyaç duyulmaktadır (Licitra, 2012). Özel olarak geliştirilen simülasyon modellerinde gürültü seviyeleri hesaplanmakta ve bu gürültü seviyelerine dayalı gürültü etkilerini ölçmek ve görselleştirmek için Coğrafi Bilgi Sistemleri (CBS) kullanılmaktadır.…”

Bu araştırmanın amacı, Aliağa limanlar bölgesinde yer alan bir limanda, operasyon sırasında meydana gelen gürültünün şiddet seviyelerinin hesaplanması ve buna bağlı gürültü yoğunluk haritalarının oluşturulmasıdır. Bu kapsamda, gürültü yoğunluk haritasının oluşturulması için, liman idari sınırları içerisinde yer alan tüm birimlerde gerçekleştirilen operasyonlardaki gürültü ölçümlerini yapabilmek amacıyla 8 ayrı ölçüm istasyonu belirlenmiştir. Gürültü seviyelerine ait veriler, kalibrasyonu yapılmış SL-814 marka gürültü seviyesi ölçüm cihazı ile elde edilmiştir. Veriler, 10.06.2019 tarihinde liman içerisinde belirlenen ölçüm istasyonlarında günde 3 defa (10:00-12:00/13:00-15:00/15:00-17:00) ölçüm yapılarak elde edilmiştir. Ölçüm sonucu bulunan gürültü değerleri ile istasyonların koordinatları ARCGIS 10.4.1 Desktop yazılımına girilerek yoğunluk haritaları oluşturulmuştur. Sonuç olarak, en yüksek gürültü değerleri operasyon yoğunluğuna bağlı olarak Rıhtım A ve CFS bölgelerinde öğle vakitlerinde (13:00-15:00) ölçülmüştür. Bu araştırmada elde edilen sonuçların sonraki çalışmalarda daha uzun bir periyot kapsamında yapılacak ölçümler ile genişletilerek bölgede gürültü düzeylerine yönelik haritaların oluşturulması ve bölgedeki diğer tesislerde de benzer ölçümlerin yapılarak gürültü düzeylerinin karşılaştırılması önerilmektedir.

“…Typical diameter of the railway wheels is slightly less than 1000 mm, for instance, standard International Union of Railways (UIC) wheel has 920 mm. 21 Also, most of the railway systems in different countries have designed worn profiles for the wheels crown, which are intended to maintain the same geometry as the wheel wears models. 22 In this study, we investigated a standard UIC wheel in Iranian railway system and the obtained results can be extended for most similar wheels.…”

In the railway systems, induced contact between wheels and rails creates maximum shear stress around the contact surfaces. These shear stresses vary with the wheel's rolling and can initiate and extend subsurface cracks in the wheel and rail. The most common subsurface cracks in the rail systems have elliptical forms. Sliding and tearing modes of the fracture can be observed due to different components of the shear stresses around the contact area. Compressive normal stress has no considerable effects on in-plane and out-of-plane shear modes for subsurface cracks. In this research, by proper modeling of the wheel and rail, the effects of dimensions, position, and depth of the subsurface cracks on the stress intensity factors of the sliding (K II ) and tearing (K III ) modes have been investigated. Also, variations of the K II and K III values versus wheel rolling angles and frictions have been considered. The validity and accuracy of the cracked model created by sub-modeling technique have been verified by half-space modeling and weight function method.
