  • 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 ...

  • 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 ...
  • 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 ...
  • Hierarchical memory synthesis in reconfigurable computers 
    Ouaiss, Iyad Elias (University of Cincinnati, 2018-02-07)
    A Reconfigurable Computer (RC) is a hardware platform that typically includes several programmable devices, memory devices, and possibly specialized devices such as analog-to-digital converters. Such high-performance ...
  • On the dynamics of systems with vastly different frequencies 
    Sheheitli, Hiba (Cornell University, 2018-02-07)
    The method of direct partition of motion (DPM) has been widely used to study the dynamics of non-autonomous oscillatory systems subject to external high frequency excitation. In this work, we explore the non-trivial dynamics ...
  • Coarse-grain artificial neural network based-model for simulating two-dimensional heat transfer in buildings 
    Abi Shdid, Caesar (University of Florida, 2018-01-25)
  • Multilayer ionic transducers 
    Akle, Barbar J. (V irginia Polytechnic Institute and State U niversity, 2018-01-22)
    A transducer consisting of multiple layers of ionic polymer material is developed for applications in sensing, actuation, and control. The transducer consists of two to four individual layers each approximately 200 microns ...
  • Characterization and modeling of the ionomer-conductor interface in ionic polymer 
    Akle, Barbar J. (Virginia Polytechnic Institute and State University, 2018-01-22)
    Ionomeric polymer transducers consist of an ion-exchange membrane plated with conductive metal layers on its outer surfaces. Such materials are known to exhibit electromechanical coupling under the application of electric ...
  • High performance applications on reconfigurable clusters 
    Nakad, Zahi (Virginia Polytechnic Institute and State University, 2018-01-19)
    Many problems faced in the engineering world are computationally intensive. Filtering using FIR (Finite Impulse Response) filters is an example to that. This thesis discusses the implementation of a fast, reconfigurable, ...
  • A full-system finite element approach to elastohydrodynamic lubrication problems 
    Habchi, Wassim (L’Institut National des Sciences Appliquées de Lyon, 2018-01-02)
    In this thesis, a full-system finite element approach to elastohydrodynamic (EHD) lubrication problems is introduced. EHD lubrication is a full-film regime where the pressure generated in the conjunction is high enough to ...
  • Accounting for risk and level of service in the design of passing sight distances 
    El Khoury, John (Virginia Polytechnic Institute and State University, 2017-12-07)
    Current design methods in transportation engineering do not simultaneously address the levels of risk and service associated with the design and use of various highway geometric elements. Passing sight distance (PSD) is ...
  • Simulation of a crash prevention technology at a mo-passing zone site 
    El Khoury, John (Virginia Polytechnic Institute and State University, 2017-12-07)
    No-passing zone crashes constitute a sizable percentage of the total crashes on two-lane rural roads. A detection and warning system has been devised and implemented at a no-passing zone site on route 114 of Southwest ...
  • Novel nanocomposite material for supercapacitor applications 
    Fawaz, Wissam (Wayne State University, 2017-12-04)
    With the rapid development of electric-based transportation and introduction of various hybrids, plug-in and full electric vehicles, there is an urgent need to develop a high power energy storage system to complement the ...
  • Neutral and risk-sensitive models for competitive bidding methods based on average and order statistics 
    Awwad, Rita Elias (University of Michigan, 2017-12-04)
    The low bid method has been the most common competitive bid selection approach used for public projects in the U.S. construction industry. This method is usually coupled with a prequalification process to ensure that the ...
