  • Behavior of axially loaded drilled shaft foundations with symmetric voids outside and inside the caging 
    Abishdid, Caesar; Hajali, Masood (2016-10-19)
    Drilled shaft foundations usually carry very high design loads, and often serve as a single load-carrying unit. These conditions have created a need for a high-level of quality assurance during and after construction ...
  • Behavior of un-reinforced concrete masonry infill walls under lateral earthquake loads. (c2016) 
    Azzi, Ziad Charbel (Lebanese American University, 2017-11-01)
    Reinforced concrete buildings with unreinforced masonry infill walls constitute the majority of new and old building inventories in the Middle East. In the absence of mandatory earthquake design requirements, such buildings ...
  • Below-Average Bidding Method 
    Awwad, Rita E.; Ioannou, Photios G. (2017-04-11)
    The low-bid method, typically used for competitive bidding in the United States, may result in a contract with a firm that submits either accidentally or deliberately an unrealistically low-bid price. Such an occurrence ...
  • Beneficial Use of Steel Slag Fines to Immobilize Arsenite and Arsenate 
    Grubb, D.; Wazne, Mahmoud; Jagupilla, S.; Malasavage, N. (2016-02-29)
    This study presents the results of an extensive beneficial-use evaluation of -in. minus steel slag fines (SSF) to immobilize arsenic. Two primary sets of experiments were undertaken to assess (1) the ability of SSF to ...
  • Benefit and risk analysis of an automatic meter reading system for electricité du Liban 
    Ghajar, Raymond F. (2017-04-28)
    This paper summarizes the benefit and risk analysis of a study for modernizing the electricity metering, billing and revenue collection systems for ´Electricit´e du Liban, the national power company of Lebanon. A cost/benefit ...
  • A bi-directional ultrasonic elliptical vibration actuator (BUEVA) for micro machining 
    Ammouri, Ali H.; Hamade, Ramsey F. (ASME, 2017-05-26)
    Presented is the detailed design and implementation of a bi-directional ultrasonic elliptical vibration actuator (BUEVA) for micro machining. Removal of material occurs via a generated elliptical tool motion resembling a ...
  • Bidirectional electronic textile token grid network topology. (c2013) 
    Khalil, Antonio F. (2013-09-03)
    Electronic Textile (e-textile) applications seem to obtain more and more importance in our daily lives; the huge amount of fabrics around us help electronic textile to mingle and integrate seamlessly with our daily life ...
  • Bifurcation and stability of structures with interacting propagating cracks 
    Tabbara, Mazen; Warren, T.L. (2016-02-10)
    A general method to calculate the tangential stiffness matrix of a structure with a system of interacting propagating cracks is presented. With the help of this matrix, the conditions of bifurcation, stability of state and ...
  • Biologically inspired highly efficient buoyancy engine 
    Akle, Barbar; Habchi, Wassim; Abdelnour, Rita; Blottman III, John; Leo, Donald (SPIE, 2017-05-30)
    Undersea distributed networked sensor systems require a miniaturization of platforms and a means of both spatial and temporal persistence. One aspect of this system is the necessity to modulate sensor depth for optimal ...
  • Biomechanical Model of the Xylem Vessels in Vascular Plants 
    Karam, Gebran (2016-02-11)
    • Background and Aims The xylem, or water transport system, in vascular plants adopts different morphologies that appear sequentially during growth phases. This paper proposes an explanation of these morphologies based on ...
  • Biomimetic jellyfish-inspired underwater vehicle actuated by ionic polymer metal composite actuators 
    Akle, Barbar; Najem, Joseph; Sarles, Stephen A.; Leo, Dona (2016-10-13)

  • Brayton cycles as waste heat recovery systems on series hybrid electric vehicles 
    Bou Nader, Wissam; Mansour, Charbel; Dumand, Clément; Nemer, Maroun (2020-09-22)
    In the global attempt to increase the powertrain overall efficiency of hybrid vehicles while reducing the battery size, engine waste heat recovery (WHR) systems are nowadays promising technologies. This is in particular ...
  • BUC algorithm for iceberg cubes 
    Nasr, George E.; Badr, Celine (2017-12-07)
    The Iceberg-Cube problem restricts the computation of the data cube to only those group-by partitions satisfying a minimum threshold condition defined on a specified measure. In this paper, we implement the Bottom-Up ...
