Abstract:
Integrated navigation using multiple Global Navigation Satellite Systems (GNSS) is beneficial to increase the number of observable satellites, alleviate the effects of systematic errors and improve the accuracy of positioning, navigation and timing (PNT). When multiple constellations and multiple frequency measurements are employed, the functional and stochastic models as well as the estimation principle for PNT may be different. Therefore, the commonly used definition of “dilution of precision (DOP)” based on the least squares (LS) estimation and unified functional and stochastic models will

Abstract BACKGROUND Glioma often recurs and the imaging evaluation whether the tumor has returned after glioma treatment is still challenging. PET/CT is one of the most important techniques to assess the post-treatment of glioma. However, differentiating tumor recurrence (TuR) from treatment effects (TrE) remains difficult. In this study, we aim to retrospectively compare the diagnostic performance of three PET tracers 13N-NH3, 18F-DOPA, and 18F-FDG on PET/CT in differentiating between TuR and TrE in post-treatment glioma patients.

Dopaminergic neurons from the SNpc project into a large subcortical structure known as the striatum, and positron emission tomography (PET) studies have demonstrated the dysfunction of the dopaminergic system in the striatum of patients with PD.

Birçok kemik sarkomu yoğun FDG tutulumu gösterirken bazı kemik sarkomları (genellikle düşük grade’li olanlar) düşük düzeyli FDG tutulumu gösterir ve tümörün agresifliği ile FDG tutulumu arasında genellikle pozitif korelasyon vardır.

Abstract The worldwide fleet of ships is ageing, with many vessels being over 15 years old. For such vessels, corrosion is an on-going concern. Thus, to guarantee structural integrity, facilitate maintenance decisions economically, and even extend the structural life, it is essential to investigate the ultimate strength of such aged and corroded ship structures based on a comprehensive understanding of the corrosion mechanisms. This work has developed numerical models simulating steel plate corrosion degradation and presents a series of novel finite element (FE) modelling to assess the influen

Abstract:
Pitting corrosion has been one of main corrosion type of immersed ship hulls, which can bring heavy damage and even accidents to in-service ships, particularly to aged ships. To investigate the effects of pits on the ultimate compressive strength of mild steel plates, a series of non-linear FEM analysis on plates with partial depth corrosion pits are undertaken in the paper, changing the size, intensity and location of pits and the slenderness of plates. It is shown that the eccentricity induced by single side distributed pits has considerable degrading effects on the ultimate compressive capa

Abstract:
Structural components of ships are subjected to corrosion, especially when exposed to sea environment. It is, therefore, essential to seek rational standards for the structural integrity of aging structures without economic penalties with respect to the repair and maintenance costs incurred over the life cycle of the structure. To make proper decisions about costs and safety, knowledge about the effect of corrosion and other degradation phenomena on the strength is of crucial importance. The main objective of the present study is to investigate the strength of pitted stiffened plates under bia

Abstract:
Corrosion pits with a conical shape are typically observed in hold frames in way of cargo holds of bulk carriers which carry coal and iron ore. The ratio of the diameter to the depth of the typical corrosion pits is in the range between 8–1 and 10–1 and its diameter might become up to 50mm. The evaluation of residual strength of members with large uneven pitting corrosion is difficult compared with that of members with general corrosion. Therefore, it is of crucial importance to develop a method for the evaluation of residual strength of pitted members. The purpose of the present study is to i

Abstract:
Abstract Most organic shale operators and capital providers believe that refracs cannot compete economically with new wells. If production from actual refracs and infill well protection is considered, the combined NPV10 is higher than that of a new well in several of the areas studied (Barba et al 2022 and 2023). The two components of the uplift are reviewed here in greater detail than previous refrac economic analyses. For this evaluation, we looked at the Eagle Ford, Haynesville, and the Midland Basin Wolfcamp age organic shales. In the first iterations of the studies, the actual declines of
