Many historical landmarks and cultural heritage are being constantly destroyed through natural events human actions. It is important to conduct corrosion analysis two three-dimension documentation studies restore transfer these the new generations. particularly record, keep heritages digitally take precautions against potential due wars, disasters climatic factors that continue present. In this...

Various nondestructive evaluation (NDE) techniques have been studied to locate steel rebars or dowel, and to detect invisible damage such as voids and cracks inside concrete and debonding between rebars and concrete caused by corrosions and earthquakes. In this study, the authors developed 3-dimensional (3D) electromagnetic (EM) imaging technology to detect such damage and to identify exact loc...

In process industries, the measurement of void fraction is considerably important for sustainable operations. The erroneous calculation of void fraction is inevitably be the cause of many industrial accidents such as loss of coolant accidents in reactor operations, sweet corrosions in sub-sea oil and gas pipelines and an in-efficient process control of chemical plants. Keeping in view the impor...

Ultrasonic guided waves inspection using Lamb waves is suitable for damage detection in metallic structures. This paper will present experimental results obtained using guided Lamb waves to detect flaws in aluminum specimens with design features applicable to space applications. Two aluminum panels were fabricated from a variable-thickness aluminum top plate, with two bolted I-beams edge stiffe...

Geleneksel Ortadoğu siyaset üslubunun yüzlerce yıl kabul gören ayırıcı yönü, halkın mustarip bulunduğu bir konu hakkında gerek bireysel gerekse çoğul biçimde şikâyetlerini yönetim katına ulaştırabilmesi olmuştur. Böylece, yandan padişah ve çevresindekiler yakınmalarını göz önünde bulundurabilmişler, diğer da halk gerektiğinde küçük pusula kaleme alarak yetkililere teslim etmek suretiyle derdini...

Testing the structural integrity of pipelines is a crucial maintenance task in oil and gas industry. This could be compromised by corrosions that occur pipeline wall. They cause catastrophic accidents are very hard to detect due presence insulation cladding around pipeline. corrosion manifests as reduction pipe wall thickness, which can detected quantified using Pulsed Eddy Current (PEC) state-...

The occurrence and densities of opportunistic pathogens (OPs), the microbial community structure, and their associations with sediment elements from eight water storage tanks in Ohio, West Virginia, and Texas were investigated. The elemental composition of sediments was measured through X-ray fluorescence (XRF) spectra. The occurrence and densities of OPs and amoeba hosts (i.e., Legionella spp....

Abstract Corrosion has been concerned as a serious safety issue for metallic facilities. Visual inspection carried out by an engineer is expensive, subjective and time-consuming. Micro Aerial Vehicles (MAVs) equipped with detection algorithms have the potential to perform safer much more efficient visual tasks than engineers. Towards corrosion algorithms, convolution neural networks (CNNs) enab...

Liquefied hydrogen storage vessels (LHSVs) are vulnerable to surface-crack initiation, propagation, and fracture on their surfaces because they under high-pressure, low-temperature conditions. Defects can also occur in the coatings of containers used prevent permeation, these lead surface defects such as pitting corrosions. Together, increase probability liquid leaks cause serious accidents. Th...

moisture and air pollutions intensify metallic and nonmetallic surface corrosions. corroded surfaces exposed to rain washing cause pollution transportation in water and soil environment, especially in industrial areas. investigation of storm runoff quality in pars special economic energy zone (pseez) has shown heavy metals in storm basins of gas refineries and petrochemical industries.in this p...
