  • Space scheduling for construction progress planning and control 
    Zouein, P.P.; Tommelien, I.D. (2018-10-15)
    Space scheduling pertains to allocating the work space to resources associated which activates in a schedule as it changes over time. This is an important aspect of materials management in dynamic environments in which ...
  • Highway geometric design changes in response to a fully autonomous vehicle fleet. (c2018) 
    Amine, Kamar Ali (Lebanese American University, 2018-10-15)
    This research investigates the potential changes in the geometric design of highway elements in response to a fully autonomous vehicle fleet. When driverless vehicles completely replace conventional vehicles, the human ...
  • Space schedule construction 
    Zouein, Pierrette P. (2018-10-15)
    The layout of temporary facilities on a construction site is affected by changes in a construction schedule, including changes in activity duration, resource selection, and resource allocation levels. Conversely, changes ...
  • Design constructability and space management 
    Zouein, Pierette; Franjieh, T. (2018-10-15)
    Design and construction have traditionally been treated as fairly separate tasks where engineers focus on the stability of the structure while contractors worry about how to get it done according to plans. Presently the ...
  • A parallel genetic algorithm for the geometrically constrained site layout problem 
    Zouein, P.; Harmanani, H.; Hajar, A. (2018-10-15)
    Parallel genetic algorithms techniques have been used in a variety of computer engineering and science areas. This paper presents a parallel genetic algorithm to solve the geometrically constrained site layout problem that ...
  • Evaluation of the marginal putage costs in electric power systems 
    Ghajar, Raymond Fouad (University of Saskatchewan, 2018-09-17)
    Electricity spot pricing has been advocated in the past few years as a potential method for assigning incremental electricity costs to the time of delivery, and sending appropriate price signals to customers. Marginal ...
  • MoveSchedule 
    Zouein, Pierette (University of Michigan, 2018-09-17)
    Site layout planning is crucial for enhancing the overall efficiency of construction operations and for reducing materials (re)location costs. More importantly, it helps identify construction time periods with potential ...
  • Forming limit diagrams 
    Issa, Jimmy (Michigan State University, 2018-09-17)
    In this work, the Marciniak and Kuczynski model (MK) will be reviewed and will be generalized to a more general approach for the calculation of forming limit diagrams. In the new model we will account for all directions ...
  • Vibration suppression through stiffness variation and modal disparity 
    Issa, Jimmy (Michigan State University, 2018-09-17)
    Vibration suppression is the main objective of this study. A semi-active and an active vibration control strategy based on stiffness variation are proposed for removing energy from vibrating structures. For the semi-active ...
  • Architectures for e-textiles 
    Nakad, Zahi S. (Virginia Polytechnic Institute and State University, 2018-09-17)
    The huge advancement in the textiles industry and the accurate control on the mechanization process coupled with cost-effective manufacturing offer an innovative environment for new electronic systems, namely electronic ...
  • Fracture and stability of strain-softening materials and structures 
    Tabbara, Mazen (Northwestern University, 2018-09-17)
    The principal object of investigation is the behavior of structures with softening load-displacement curves. The study deals with three interrelated areas: (1) a model for fracture of aggregate composites, (2) stability ...
  • The mechanisms of uranium removal from water by iron oxyhydroxides, nanocrystalline titanium dioxide, and elemental iron 
    Wazne, Mahmoud (Stevens Institute of Technology, 2018-09-17)
    The removal mechanisms and efficiencies of uranium from water by iron oxyhydroxides, nanocrystalline titanium dioxide, and elemental iron were investigated in artificial and natural systems. Batch tests, zeta potential ...
  • Simulating and comparing various price-driven bid selection methods from an owner's perspective. (c2017) 
    Ammoury, Michael Fayez (Lebanese American University, 2018-03-06)
    In the construction industry, it is crucial for owners to select the appropriate contract delivery method in order to achieve best performance on their projects. The low bid method has been the most common competitive bid ...
  • Free space optical communication systems with multiuser diversity. (c2017) 
    Chami, Mohammad (Lebanese American University, 2018-03-06)
    We explore the performance of N-user multi-point-to-multi-point Free Space Optical (FSO) communication systems. For such systems, the communication between the N transmitters and N receivers relies on user grouping for ...
  • Damage and life cycle assessment of new-generation wide-base tires in New Brunswick, Canada. (c2017) 
    Said, Izak (Lebanese American University, 2018-03-06)
    Wide-base tires (WBT) provide environmental benefits compared with conventional dual-tire assemblies (DTA), but research has consistently showed higher pavement responses and potential damage due to the use of WBT. Even ...
  • A Terrain classification system for coseismic landslide hazard analysis: Lebanon, a case study 
    Grant, Alex R.; Wartman, Joseph; Abou-Jaoude, Grace (2018-03-01)
    Coseismic landslides have caused vast amounts of damage throughout history, and are often responsible for more damage than all other seismic hazards combined (Kramer, 1996). To better assess coseismic landslide hazard on ...
