Deep learning techniques for liver and liver tumor segmentation: A review
( Elsevier , 2022 , Article)Liver and liver tumor segmentation from 3D volumetric images has been an active research area in the medical image processing domain for the last few decades. The existence of other organs such as the heart, spleen, stomach, ... -
Defect based deterioration model for sewer pipelines using bayesian belief networks
( Canadian Science Publishing , 2017 , Article)A defect based deterioration model to determine the condition ratings in a probabilistic manner for sewer pipelines is presented in this paper. Bayesian belief network (BBN) is used to develop a static model using probabilities ... -
Defect based risk assessment model for prioritizing inspection of sewer pipelines
( American Society of Civil Engineers (ASCE) , 2018 , Conference Paper)In presence of financial constraints and dire need for inspecting deteriorated sewer pipelines, inspection prioritization tools are required. This paper presents a defect based risk assessment model for prioritizing ... -
Defect-based ArcGIS tool for prioritizing inspection of sewer pipelines
( American Society of Civil Engineers (ASCE) , 2018 , Article)This paper presents a defect-based model for assessing risk of failure for sewer pipelines. The proposed model deploys a Sugeno fuzzy inference system to create a risk index from which inspection and replacement activities ... -
Defect-Based Condition Assessment Model for Sewer Pipelines Using Fuzzy Hierarchical Evidential Reasoning
( American Society of Civil Engineers (ASCE) , 2021 , Article)Assessing the condition of sewer pipelines is essential for addressing associated problems as a result of deterioration to maintain functionality and avoid additional social costs. This paper presents the development of a ... -
Defensive or competitive Autonomous Vehicles: Which one interacts safely and efficiently with pedestrians?
( Elsevier , 2022 , Article)The emergence of Autonomous Vehicles (AVs) could provoke unexpected challenges in urban traffic environments. One such crucial challenge is the conflicts between pedestrians and AVs, particularly on unsignalized mid-block ... -
Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones
( Elsevier , 2022 , Article)Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and can provide information ... -
Demonstrating the Worth of Recycled Aggregates - A Case Study from Qatar
( American Society of Civil Engineers (ASCE) , 2016 , Conference Paper)Recycled aggregates are widely used in unbound applications in many countries. However, in some areas the materials available may not meet all the requirements of the local specifications. This is the case in Qatar, where ... -
Design and Implementation of a Smart Insole System to Measure Plantar Pressure and Temperature
( MDPI , 2022 , Article)An intelligent insole system may monitor the individual's foot pressure and temperature in real-time from the comfort of their home, which can help capture foot problems in their earliest stages. Constant monitoring for ... -
Design and Performance Evaluation of a Novel Spiral Head-Stem Trunnion for Hip Implants Using Finite Element Analysis
( MDPI , 2023 , Article)With an expectation of an increased number of revision surgeries and patients receiving orthopedic implants in the coming years, the focus of joint replacement research needs to be on improving the mechanical properties ... -
Determination of stiffness modulus and poisson's ratio of lightly stabilized granular materials from indirect diametral tensile testing
( ASTM International , 2016 , Article)Lightly cementitiously stabilized granular materials are generally characterised by their tensile properties that are required for the analysis and design of a pavement structure involving these materials. Tensile properties ... -
Determining relative weights of sewer pipelines' components and defects
( American Society of Civil Engineers (ASCE) , 2018 , Article)Condition assessment models for sewer network components can be considered a tool for key personnel to make informed decisions regarding the required interventions on the basis of the current conditions of these components. ... -
