Uncertainty and sensitivity analysis methods are introduced, concerning the quality of spatial data as well as that of output information from Global Positioning System (GPS) and Geographic Information System (GIS) integrated applications for transportation. In the methods, an error model and an error propagation method form a basis for formulating characterization and propagation of uncertaint...
Over the past few decades, earthquake engineering research mainly focused on the effects of strong seismic shaking. After the 1999 earthquakes in Turkey and Taiwan, and thanks to numerous cases where fault rupture caused substantial damage to structures, the importance of faulting-induced deformation has re-emerged. This paper, along with its companion (Part II), exploits parametric results of ...
The use of enzymes coupled with supercritical fluid (SF)-based analytical techniques, such as supercritical fluid extraction (SFE), provides a safer environment platform for the analytical chemist and reduces the use of organic solvents. Incorporation of such techniques not only reduces the use of solvent in analytical laboratories, but it can also lead to overall method simplification and time...
The design of underground spaces is mainly carried out using empirical, analytical, and numerical methods. The convergence confinement method (CCM) is an analytical technique that is widely utilized in analyzing the stability of underground spaces. However, the main challenge in the stability analysis is the selection of an accurate constitutive model for rock mass, and particularly, its post-f...
The use of rapid and ultra-rapid analytical methods in the pharmaceutical domain is mandatory in the drug discovery, drug development, and quality control steps. Liquid chromatography (LC) and capillary electrophoresis (CE) are therefore particularly studied in the Laboratory of Pharmaceutical Analytical Chemistry (LCAP) to perform fast and ultra-fast analyses of drugs present in different matr...

This review describes a comprehensive investigation focusing on syntheses of analytical reagents, followed by their utilization in development of analytical methods, and leading to practical applications for rational use of medicaments centering on abused drugs. Many kinds of analytical reagents for fluorescence and chemiluminescence detections have been synthesized with the intention of improv...
BACKGROUND Dynamic contrast-enhanced MRI (DCE-MRI) biomarkers have proven utility in tumors in evaluating microvascular perfusion and permeability, but it is unclear whether measurements made in different centers are comparable due to methodological differences. PURPOSE To evaluate how commonly utilized analytical methods for DCE-MRI biomarkers affect both the absolute parameter values and re...
With the introduction of capillary electrophoresis (CE), a new generation of electrophoretic techniques has seen the light of day. The scientiRc literature today describes a large number of applications of this powerful analytical technique in the analysis of nucleic acids. For nucleic acids, as for most other analytes, CE offers signiRcant advantages over many of the conventional electrophoret...
The available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. In the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. These non-uniform ...
