Influence of sensor density on seismic damage assessment: A case study for istanbul
(Seismological Society of America, 2022-08)The strong ground motions (GMs) recorded by strong motion networks are significant to increase the accuracy of seismic damage assessment. However, the influence of sensor density on seismic damage assessment remains ... -
Influence of Sporasarcina pasteurii cells on rheological properties of cement paste
(Elsevier, 2019-11-20)Nowadays with the developments in the concrete materials technology, researches started to focus on highly flowable mixes with improved rheological properties. These highly flowable mixes generally require use of viscosity ... -
Interaction of a pile with layered-soil under vertical excitations: field experiments versus numerical simulations
(Springer International Publishing, 2017-09)Data recorded during a field test involving an instrumented drilled shaft under vertical excitations are examined in order to (1) extract the soil–pile system’s dynamic impedance, and (2) to evaluate the small-strain shear ... -
An investigation of the effects of surface topography on the seismic structural demands for a region of istanbul
(CRC Press, 2019)In this study, we provide preliminary results from an ongoing study—funded by The Scientific and Technological Research Council of Turkey, TUBITAK—investigating the effects of site-specific surface topography and soil ... -
Investigation of the extent of field data required for reliable calibration and validation of large scale traffic simulation models: A case study
(IEEE, 2020-09-20)Availability, accuracy and relevance of field data are essential for developing a reliable simulation model. Large scale simulation models in particular require data from many sources and in great detail. Considering the ... -
Local site conditions and seismic risk assessment of historic buildings
(2013)The objectives of the Istanbul Seismic Risk Mitigation and Emergency Preparedness Project are to improve Istanbul’s preparedness for a potential earthquake. Within this framework “Risk Assessment of Cultural Heritage ... -
Mapping the scientific research of the life cycle assessment in the construction industry: A scientometric analysis
(Elsevier, 2021-10-15)The interest toward the life cycle assessment studies in the construction industry has been increasing in the last decades. However, there is no existing study that focuses on mapping the scientific research of the LCAs ... -
Micro-a-fluidics ELISA for rapid CD4 cell count at the point-of-care
(Nature, 2014-01-22)HIV has become one of the most devastating pathogens in human history. Despite fast progress in HIV-related basic research, antiretroviral therapy (ART) remains the most effective method to save AIDS patients' lives. ... -
Microchip ELISA coupled with cell phone to detect ovarian cancer HE4 biomarker in urine
(Springer Science+Business Media, 2014)Ovarian cancer is a leading cause of death from gynecologic cancers in the USA, and early diagnosis can potentially increase 5-year survival rate. Detection of biomarkers derived from hyperplasia of epithelial tissue by ... -
Microzonation with respect to ground shaking intensity
(CRC Press, 2019)Seismic microzonation is conducted to assess the seismic hazard on the ground surface with respect to ground shaking intensity. A probabilistic seismic hazard study is conducted to define earthquake characteristics on the ... -
Mixed method review for integrating building information modeling and life-cycle assessments
(Elsevier, 2020-04-15)Previous studies have suggested that building information modeling (BIM) and life-cycle assessments (LCAs) could be integrated to quantify and alleviate the environmental effects of buildings while simplifying and optimizing ... -
Multi-criteria decision-making model for risk management in modular construction projects
(Taylor & Francis, 2024)The modular sector needs a precise guide to determine the most efficient risk management approaches. The main research objective of this study is to develop a multi-criteria decision-making model to find the most efficient ... -
A new embankment construction method through the analysis of possible failure mechanisms in soft soils
(International Society for Soil Mechanics and Geotechnical Engineering, 2019)A new method to analyze the failure behavior of embankments on soft soils is proposed in this paper. The proposed method is based on the evaluation of stability considerations applied on a possible mechanism which can be ... -
Nonlinear dynamic behavior of the basins with 2D bedrock
(Elsevier, 2018-04)Resonance due to impedance contrast, focusing due to subsurface topography, conversion of the body waves to surface waves and subsurface topography are among the factors influencing the amplification specification of the ... -
Numerical analysis of segmental tunnel linings - Use of the beam-spring and solid-interface methods
(Techno-Press (테크노프레스), 2022-04-16)The effect of segmental joints is one of main importance for the segmental lining design when tunnels are excavated by a mechanized process. In this paper, segmental tunnel linings are analyzed by two numerical methods, ... -
Numerical modeling of the offshore wind turbine monopile foundation under environmental loading
(CRC Press, 2019)Prediction of dynamic performance of an offshore wind turbine requires consideration of many different design parameters. Beside the superstructure, foundation also plays an important role both functionally and financially ... -
Observations from geotechnical arrays in Istanbul
(Springer, 2015-04-16)Few small earthquakes with local magnitude slightly larger than ML = 4 were recorded by geotechnical downhole arrays that have been recently deployed in the west side of Istanbul. Same events were also recorded by Istanbul ... -
