WEIBULL DISTRIBUTION BASED ON EDUCATION PARTLY INTERVAL CENSORED DATA
(Applied Statistics, 2018 , Professional Masters Project)
The work in this project is concerned with the applying of techniques for the assessment of survival analysis in data that include censored observations. Survival analysis has a lot of achievement in the medical, engineering, ...
Relationship between structure, properties and UV/Heat protection behavior of two different types of polyethylene manufactured in Qatar
(Material Science and Technology, 2021 , Professional Masters Project)
Accelerated (artificial) weathering and thermal ageing tests were performed
to investigate the effectiveness of different UV/HALS formulations in reducing the
UV/heat degradation effect for two different low-density ...
Exploring the Students and Faculty Members Attitudes and Awareness about the Use Of E-Textbooks At Qatar University
(Applied Statistics, 2020 , Professional Masters Project)
Digitalization plays a big role in world and has an effect on the tools of learning.
In 2013, e-Textbooks became commonly used in most science core curricula and some
literary curricula at Qatar University. However, ...
Nutrient consumption over time in plant litter decomposition in drylands: effects of different species mixtures and Photodegradation
(Environmental Sciences, 2021 , Professional Masters Project)
Plant litter decomposition in soil is a dynamic process that is affected and
regulated by several factors. Soil microbial activity, light intensity, litter composition
and habitat all affect the rate of decomposition ...
ASSESSMENT OF ORDERING PRACTICES AT BIOMEDICAL RESEARCH CENTER (BRC)- METABOLIC RESEARCH LABORATORY (MRL)
(Biomedical Sciences, 2021 , Professional Masters Project)
Background: Assessment of the purchasing and ordering process in the
Metabolic Research Laboratory (MRL) at the Biomedical Research Center (BRC) at
Qatar University (QU) is a critical component of the quality management ...
INDOOR AIR QUALITY OF OFFICE BUILDINGS IN IDUSTRIAL COMPLEX
(Biological and Environmental Science, 2018 , Professional Masters Project)
Measurement of air quality in the places where people are used to spend a large amount of their time is essential. Hazardous substances emitted by anthropogenic activities, building construction materials, indoor equipment ...
Reliability analysis of the Stress-Strength model from truncated Pareto distribution based on progressive Type-II censored samples.
(Applied Statistics, 2023 , Professional Masters Project)
In this project, we studied the stress strength reliability (SSR) models. The stress-strength model has many applications in engineering problems, for example the strength of a building being subjected to earthquake, the ...
Development Of A Protocol For Culturing And Maintaining Seagrass, Halodule Uninervis, Under Laboratory Conditions And Its Application To Determine Impacts Of Light On Seagrass Growth
(Environmental Sciences, 2019 , Professional Masters Project)
Seagrass meadows are an important component of the marine ecosystem as they not only contribute nutrients and organic carbon to the nutrient cycle, but also, provide food, habitat and nursery grounds for a plethora of ...
FACTORS AFFECTING ACADEMIC DISCIPLINE SELECTION AND ACADEMIC PERFORMANCE OF 12TH GRADE STUDENTS IN QATAR
(Applied Statistics, 2022 , Professional Masters Project)
COVID-19 pandemic has led to the lockdown of major cities worldwide, which caused the early closure of schools and educational institutions in the towns affected. This pandemic had a negative impact on the performance of ...
Accelerated failure time for Weibull distribution based partly interval censored data
(Applied Statistics, 2021 , Professional Masters Project)
In this project, the performance of maximum likelihood estimators of the
parameters of Accelerated Failure Time (AFT) regression model based on Weibull
distribution with simple imputations methods under Partly-Interval ...
