Segmentation of Tumor Regions in Microscopic Images of Breast Cancer Tissue
(2016 , Master Thesis)Nowadays, advances in the domain of digital pathology gave the means to replace the old optical microscopes by the Whole Slide Imaging (WSI) scanners. These scanners enable pathologists viewing conventional tissue slides ... -
Segmenting Liver Volume for Surgical Analysis
( Qatar University Press , 2021 , Poster)Introduction: Almost two million people worldwide die annually due to hepatic-related diseases. Half of these diseases are attributed to cirrhosis and the other half are related to hepatitis and hepatocellular carcinoma ... -
SEIRD model for Qatar COVID-19 outbreak: A case study
( Intercollegiate Biomathematics Alliance , 2021 , Article)The COVID-19 outbreak of 2020 has required many governments to develop mathematical-statistical models of the outbreak for policy and planning purposes. This work provides a tutorial on building a compartmental model using ... -
Seismic Assessment of Existing Lowrise and Midrise Reinforced Concrete Buildings Using the 2014 Qatar Construction Specification
( American Society of Civil Engineers(ASCE) , 2018 , Article)Qatar is considered to have predominantly low seismic activity despite being close to some of the most active seismic zones in the world, including the Zagros thrust belt. However, the strong earthquakes that have recently ... -
Seismic detection and characterization of a man-made karst analog - A feasibility study
( Society of Exploration Geophysicists , 2021 , Article)At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ... -
Seismic detection of a sinkhole using spectral-based analysis
( Society of Exploration Geophysicists , 2014 , Conference Paper)Seismic data recorded during a survey in the vicinity of a sinkhole revealed distinct resonances at 70 Hz. Frequency domain data inversion based on exact modeling produced effective elastic parameters for the location over ... -
Seismic reflection coefficient parameter-theoretical and Practical approach
( Qatar University , 1994 , Article)In this study, the effect of porosity and pore filler on the reflection coefficient parameter (R), are well deduced and some mathematical expressions were developed. This leads to the establishment of new expression of (R) ... -
Seismic Resolvable Frequency Band For The Pre-Miocene Oil Targets Ras Budran, Gulf Of Suez, Egypt
( Qatar University , 1988 , Article)Seismic attenuation problem in Ras Budran area, Gulf of Suez was tackled by defining the resolvable frequency band. This band can transmit through the Miocene evaporitic cyclic section and hit pre-Miocene oil targets. This ... -
Seismic Risk Evaluation Based on Maximum Likelihood Technique Applied For the Red Sea Region
( Qatar University , 1993 , Article)An analysis of the seismic risk is carried out for the Red Sea region for the recorded earthquakes in the area between 1. January 1913 and 31 December 1982. The maximum likelihood method was applied to determine the hazard ... -
Selected harmonics elimination in multilevel inverter using improved numerical technique
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)For medium voltage high power application the modulation technique for power converters based on pre-computed Pulse Width Modulation (PWM) switching patterns can be very useful since the generated harmonic content can be ... -
