  • Life cycle cost analysis : a decision tool for public procurement award 
    Medawar, Yara (Notre Dame University-Louaize., 2020-05)
    Sustainable development has been tackled for the last four decades in various fields from education, management, climate change to politics all over the world. One of the major challenges faced by humanity nowadays is achieving the economic sustainability of our infrastructure facilities. To fulfill it, an economic tool called Life Cycle Cost Analysis (LCCA), which takes into account all costs of an asset during its lifetime, is being used. In some countries, this technique is being incorporated in the procurement. It is used as a decisive factor in the procurement of their infrastructure ...
  • Modeling of groudwater flow and contaminant transport in a karstic formation using finite diffference approach 
    Fadlallah, Jeffrey Joseph (Notre Dame University-Louaize., 2020-05-12)
    Lebanon is considered naturally water rich compared to other countries in the Middle East and North Africa region owing to heavy rainfall and snowfall in winter season and the prevalence of Karstic geology. Though, overexploitation and mismanagement of water resources along with poor sanitation practices have led to water shortage and groundwater contamination. Consequently, there is a need to assess the groundwater flow and contaminant transport in Karstic aquifers in order to have a better understanding of groundwater movement through karst conduits until reaching a certain discharge or ...
  • MSW management via PPP in Lebanese medium-size communities 
    El Meouchy, Paolo (Notre Dame University-Louaize, 2020)
    Public authorities around the world have been historically responsible for the management of their municipal solid waste. The burden of this task has been increasing through the years considering the rapid expansion of urban cities and their corresponding populations along with a decline in land availability. The escalating figures in municipal solid waste generation increased the technical and financial challenges faced by local authorities, especially in developing countries. In the case of Lebanon, political conflicts and corruption, weak law enforcement and lack of planning in addition to ...
  • On the modeling of the effective thermal conductivity of particulate composites and the influence of building porosity on the shielding of blast waves 
    Dib, Nancy (2022)
    The main and overarching objective of this research endeavor is to devise data-driven soft modeling tools that can provide fast, fairly accurate and computationally efficient predictions for: (1) the thermal conductivity of particulate composites (PC), and (2) the level of shielding provided by a porous structure from a high-yield explosion. The computational tools developed in this work constitute cheaper and faster alternatives to the relatively large and cumbersome numerical simulations or experimental testing campaigns that would otherwise be needed to make predictions of comparable ...
  • The penetration and impact of BIM implementation in the construction industry in Lebanon 
    Matar, Joseph (Notre Dame University-Louaize, 2019-05)
    Purpose – The topic of this thesis focuses on the Lebanese Construction Industry as it has been lagging in terms of technological advancements in the last few years. The purpose of this thesis is to find out the impact of technological advancements, specifically Building Information Management and Modeling, on the Lebanese Construction Industry, its penetration in the market in Lebanon in comparison to the MENA region, in addition to estimating the payback period of investments in BIM for small and medium engineering consultancy offices. Design/methodology/approach-Philosophic Approach and ...
  • Resilience of urban infrastructure prone to natural hazards 
    Rouhana, Francesco (Notre Dame University-Louaize., 2020)
    Civil infrastructure systems such as transportation networks, power gridlines, water and wastewater networks, telecommunication services are vital modules creating the backbones of modern cities. Transportation networks are key components of civil infrastructure systems that can impede societal and commercial events, and impair post-disaster evacuation, response and recovery. Performance of transportation networks under natural hazards shed light on the necessity to assess their fundamental topological properties in order to provide and correlate appropriate resilience measurements to comprehend ...
  • Risk management in procurement of construction industry in Lebanon 
    Haddad Barouke, Charbel Nassif (Notre Dame University-Louaize, 2020)
    Given the high complexity of construction projects, these projects carry numerous inherent risks and uncertainties. Such risks if managed properly can turn threats into opportunities. With the current decline in the construction and economic sectors in Lebanon, the application of risk management in construction projects has become imperative and more needed than ever. This master’s thesis looks into the current state of-the-practice of risk management in construction projects in Lebanon focusing on procurement methods in these projects to identify the main obstacles in its application. The thesis ...
  • The stress strain response of concrete laterally confined with low and high performance fiber-reinforced cements and polymer composites : a comparative experimental and theoretical study 
    Sarieldine, Rawan Osmat (Notre Dame University-Louaize, 2020)
    While concrete, steel and Fiber Reinforced Polymer (FRP) jackets are the most commonly used types of jackets in the industry to confine columns, the focus of this research is to study and compare the compressive behavior of concrete cylinders confined with different types of fibrous composites; including Fiber Reinforced Concrete (FRC), Fiber Reinforced Mortar (FRM), and Slurry Infiltrated Fiber Concrete (SIFC). This study will provide a broad understanding of the behavior of the different confinement types used to retrofit columns to resist detrimental loads including blast and impact. The study ...
  • Towards a more sustainable water management scheme for Qatar 
    Al Khoury, Ibrahim Gaby (Notre Dame University-Louaize, 2021)
    Qatar is an arid country with limited natural freshwater resources due to low rainfall and high evapotranspiration. The country, having the third largest natural gas reserve in the world, relies primarily on fossil fuel-powered seawater desalination to meet domestic water demand, estimated at around 600 liters per capita per day. Additionally, groundwater is being depleted to supply the agricultural sector, which consumes about 230 million cubic meters of freshwater each year. Hence, this paper aimed at improving the sustainability of the water management scheme of Qatar by developing a combination ...
  • Urban resilience to pandemics : a multi-faceted framework for cities resilience quantification 
    Salameh, Lourdes (Notre Dame University Louaize, 2020)
    The current coronavirus outbreak (COVID-19) affected 218 territories around the world, infected more than 60 million people, and killed more than one million. It is expected that the number of cases will continue to increase unless a vaccine becomes available to all countries. However, the coronavirus outbreak is much more than a health crisis. This pandemic poses numerous challenges on different sectors and exacerbates existing inequalities. COVID-19 exposed major problems with our cities and highlighted their limited resilience. In an ever-more interconnected world (social, environmental, ...
