  • Restructuring of the lebanese electric power sector 
    Ghajar, R.F. (Acta, 2017-08-22)
    This paper examines the current structure of the Lebanese electric power sector and proposes a number of alternatives for unbundling the traditional services of generation, transmission and distribution. The proposed ...
  • ISSP 
    Zouein, P.P.; Shedid, D. (ASCE, 2017-08-21)
    This paper presents the ISSP system for activity scheduling and site layout planning under spatial constraints. The importance of tying schedule and layout data has been established and dealt with extensively in the ...
  • Space-time characterization for resource management on construction sites 
    Zouein, Pierrette P.; Tommelein, Iris D.; Castillo, Juan G. (ASCE, 2017-08-21)
  • Time-space tradeoff strategies for space-schedule construction 
    Zouein, Pierrette P. (ASCE, 2017-08-21)
    Space availability on a construction site can have a major impact on the efficiency and constructability of a project. Especially when space is limited, tradeoffs between activity sequencing, construction method selection, ...
  • Automating dynamic layout construction 
    Zouein, P.P.; Tommelien, I.D. (Elsevier Science, 2017-08-21)
    A critical problem in dynamic environments and especially on construction sites is coordinating the use of limited space to accommodate resources and their changing demand for space over time. This paper presents a heuristic ...
  • Exchanging layout and schedule data in a real-time distributed environment 
    Zouein, P.; Tommelein, Iris D.; Dzeng, Ren-Jye (ASCE, 2017-08-21)
    Unpredictable site conditions and unforeseen changes in construction work may result in inefficiencies due to a shortage of work space and difficult access to critical areas on site. This hampers productivity. Detailed ...
  • Storage yard layout at container terminals 
    Zouein, P.; Saade, L. (Acta, 2017-08-09)
    Beirut Container Terminal (BCT) is the only port facility available in Lebanon that handles all sea trade Lebanon does with foreign countries. Optimizing its container handling and storage operations is vital for its growth ...
  • Optimal airline overbooking policy for a single leg with multiple flights per day 
    Zouein, P.; Abillama, W. (Acta, 2017-08-09)
    This paper addresses the problem of determining optimal overbooking policies on a single flight leg with multiple daily flights. In particular, it solves for the optimal booking level to accept on each of n daily flights ...
  • Near-surface topology and flow structure on a delta wing with low sweep angle 
    Elkhoury, Michel; Yavuz, Metin; Rockwell, Donald (APS, 2017-08-03)
    The patterns of streamline topology, surface-normal vorticity and fluctuating velocity are characterized immediately adjacent to the surface of a delta wing having a low sweep angle (Λ=38º) using a cinema technique of ...
  • Flow Structure and Surface Topology on a UCAV Planform 
    Elkhoury, Michel; Yavuz, Metin; Rockwell, Donald (APS, 2017-08-03)
    Flow past a X-45 UCAV planform involves the complex generation and interaction of vortices, their breakdown and occurrence of surface separation and stall. A cinema technique of high-image-density particle image velocimetry, ...
  • An improved wall-distance-free version of the Baldwin-Barth turbulence model 
    Elkhoury, Michel (ASME, 2017-08-03)
    This paper presents a modified version of the Baldwin-Barth (BB) turbulence model. This modification accounts for the asymptotic boundary value of the pseudo eddy viscosity as the wall is approached. The BB Model tends to ...
  • URANS modeling of three airfoils with different stall mechanisms 
    Elkhoury, M.; Najem, J.; Nakad, Z. (ASME, 2017-08-03)
    Capability of recently developed Menter (ME) and Modified Menter (MME) one-equation models in predicting prestall and poststall characteristics of three airfoils that exhibit different stall onset mechanisms is investigated. ...
  • Modeling of oblique penetration into geologic targets using cavity expansion penetrator loading with target free-surface effects 
    Tabbara, Mazen R.; Jung, Joe; Longcope, Donald B. (Scitech Connect, 2017-04-11)
    A procedure has been developed to represent the loading on a penetrator and its motion during oblique penetration into geologic media. The penetrator is modeled with the explicit dynamics, finite element computer program ...
  • Localization instabilities due to damage and fracture propagation 
    Tabbara, Mazen R.; Bazant, Zdenek P. (ASCE, 2017-04-11)
    In recent research it has become clear that localization of damage due to strain softening as well as propagation of interactive cracks can result in bifurcations of the loading path characterized by localization of damage ...
  • Spherical cavity-expansion forcing function in PRONTO 3D for application to penetration problems 
    Tabbara, Mazen R.; Warren, Thomas L. (Scitech Connect, 2017-07-31)
    In certain penetration events the primary mode of deformation of the target can be approximated by known analytical expressions. In the context of an analysis code, this approximation eliminates the need for modeling the ...
  • Knowledge integration in large-scale organizations and networks – Conceptual overview and operational definition 
    Haddad, Marc; Bozdogan, Krikor (SSRN, 2017-05-23)
    Knowledge integration is an emerging discipline in organizational science where the central proposition is that the increasing complexity of products and services being developed and delivered, means that the knowledge ...
  • Environmentally-friendly replacement for mercurous nitrate test of copper alloys 
    Wazne, Mahmoud; Billapati, Sant-Sri; Christodoulatos, Christos; Jasinkiewicz, Kristin L.; Hespos, Micheal; Hogrelius, Kimberly E. (2017-04-26)
    Brass cartridge cases are tested for tensile residual stresses by mercurous nitrate immersion in accordance with ASTM B154. The test has been used for many years as an accelerated, lot acceptance test to detect tensile ...
  • Removal of Depleted Uranium from Water Using Titanium Dioxide 
    Wazne, Mahmoud; Choy, Christine Chin; Meng, Xiaoguang (2017-04-07)
    Groundwater contamination with depleted uranium (DU) is a concern in many areas where uranium mining or uranium processing and recycling have occurred. Uranium typically migrates with groundwater as uranyl carbonates and ...
