  • Unmanned aerial vehicles as store-carry-forward nodes for vehicular networks 
    Fawaz, Wissam; Atallah, Ribal; Assi, Chadi; Khabbaz, Maurice (2019-10-03)
    A fully connected vehicular ad hoc network (VANET) establishes a strong foundation for the development of smart cities, where one of the main objectives is the improvement of the welfare of commuting passengers. The ...
  • Unorganized loan markets and monetary policy instruments 
    Shahin, Wassim (2016-05-05)
    The paper uses a portfolio balance model to examine the relationship between monetary policy instruments and the unorganized loan rate. Predicting the direction of the change in this rate as a result of varying a policy ...
  • Unpacking the spillovers of the multifaceted Iranian-Saudi Arabian rivalry on Lebanon 
    Salem, Nour (2023-04-07)
    Reclaiming the mantle of Islamic leadership has led Iran and Saudi Arabia to engage in proxy-wars to counter each other’s efforts in ruling the region. Both rivals target weak States as Lebanon to exert their influence ...
  • Unraveling Hizbullah's institutional paradox. (c2012) 
    Khoshian, Meghry (Lebanese American University, 2012-09-26)
    Scholarship addressing Hizbullah’s military and political aspects is vast. Yet, the literature is relatively limited when examining Hizbullah as a social service provider. This thesis looks at the party as a social and ...
  • Unravelling the financial stability oversight council 
    El Mallah, Karim (Lebanese American University, 2019-05-21)
    The 2007-2008 financial crisis was a devastating on many households peaking global unemployment at 10% and dropping Global GDP by 5%. To deter another financial crisis the United States government passed the most complex ...
  • An unstaggered central scheme on nonuniform grids for the simulation of a compressible two-phase flow model 
    Touma, Rony; Zeidan, Dia (2018-09-10)
    In this paper we extend a central finite volume method on nonuniform grids to the case of drift-flux two-phase flow problems. The numerical base scheme is an unstaggered, non oscillatory, second-order accurate finite volume ...
  • Unstaggered central schemes for hyperbolic systems 
    Touma, Rony (2018-09-07)
    We develop an unstaggered central scheme for approximating the solution of general two‐dimensional hyperbolic systems. In particular, we are interested in solving applied problems arising in hydrodynamics and astrophysics. ...
  • Unstaggered central schemes for MHD and SMHD 
    Touma, Rony (2018-09-07)
    We develop second-order nonoscillatory unstaggered central schemes (UCS) with a constrained transport-type method to solve one and two-dimensional hyperbolic problems arising in astrophysics. In contrast with the original ...
  • Unstaggered central schemes with constrained transport treatment for ideal and shallow water magnetohydrodynamics 
    Touma, R. (2016-04-07)
    We propose an unstaggered, non-oscillatory, second-order accurate central scheme for approximating the solution of general hyperbolic systems in one and two space dimensions, and in particular for estimating the solution ...
  • Unsupervised Feature-Based Visualization Tool Applied on Medical Data 
    Moufarrej, Angela Sleiman (Lebanese American University, 2020-12-20)
    In a time when data is experiencing a remarkable growth in different fields, extracting and understanding the correlations between different data features is becoming increasingly important in many application areas, ranging ...
  • Unsustainability in emergent systems 
    Haddad, Marc; Mansour, Charbel; Stephan, Jad (IEEE, 2017-06-12)
    The land transportation network in Lebanon faces continuing and wide-ranging challenges at the level of infrastructure development, planning and overall system management. These challenges are already significant enough ...
  • Unusual case of difficult double-lumen endotracheal tube removal 
    Yammine, Joseph N.; Yazbek-Karam, Vanda G.; Haswani, Roula W.; Karam, Hoda S.; Haddad, Walid M.; Youssef, Pierre S. (2019-05-02)
    A reusable Robertshaw red rubber double-lumen endotracheal tube (DLT) was placed to facilitate lung isolation for thoracoscopy in a 49-year-old atopic patient. In spite of its smooth insertion, it was then not possible to ...
  • Unusual skin pigmentation in a patient with human immunodeficiency virus (HIV) infection 
    Mokhbat, Jacques; El-Saad Debahy, N.; Aoun, J. P.; Hajjar, E. (2017-02-15)
    Diffuse addisonian hyperpigmentation in a male patient with acquired immunodeficiency syndrome related complex (ARC) is described. The etiology of pigmentation in this patient remains obscure but is most probably related ...
  • Unveiling the unseen toll: exploring the impact of the Lebanese economic crisis on the health-seeking behaviors in a sample of patients with diabetes and hypertension 
    Cherfane, Michelle; Boueri, Myriam; Issa, Elio; Abdallah, Racha; Hamam, Ali; Sbeity, Kassem; Saad, Anthony; Abi-Gerges, Aniella (2024-03-01)
    Background Against the backdrop of Lebanon’s escalating multifaceted crisis which resulted in medication shortages for chronic diseases and unaffordable healthcare services, the current study endeavors to shed light on a ...
