  • A heuristic algorithm for operating yard cranes over storage blocks to minimize the handling time in a container yard

    Creator:
    Denkaew, Weerakit
    Abstract:
    In container terminals, the efficiency of loading operations in a container yard highly depends on the productivity of yard cranes. In loading operation, yard cranes have to pick-up the containers which are stacked in the yard-bays to satisfy the work schedule requirement of quay crane, the equipment for loading and...

  • Optical sensing and metrology for on-machine surface inspection in manufacturing processes

    Creator:
    Lee, Eddie T.
    Abstract:
    Optical sensing technologies are pivotal in the manufacturing process, specifically in defect detection, tool condition estimation, and monitoring. The research aims to enhance the accuracy, efficiency, and reliability of manufacturing metrology by employing optical sensing technologies, such as laser profilometers and image processing techniques. The dissertation proposes intelligent and flexible...

  • About good work

    Creator:
    Lee, Wei-Tau
    Abstract:
    This research is an effort to explore the nature of good work, a concept that describes work that is beneficial to the physical, psychological, and social dimensions of its stakeholders, including and especially the worker. This effort is divided into four distinct parts. First, the construct of good work is...

  • Characterization of flow boiling in a fractal–like branching microchannel network

    Creator:
    Edward, Lee M.
    Abstract:
    Based on experimental investigations the present study evaluates flow instability and void fraction in a fractal-like branching microchannel network with rectangular cross-section. The hydraulic diameter of the channels ranged from 308μm at the inlet to 143μm at the outlet. The flow network used is characterized by set branching ratios for...

  • Discovery, Processing and Characterization of New Copper and Hafnium-based Metallic Glass Alloys

    Creator:
    Saini, Jaskaran S.
    Abstract:
    Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

  • Modeling and development of fabrication method for embedding membrane based microvalve in bulk microfluidic device

    Creator:
    Abhinkar, Bindiya S.
    Abstract:
    PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...

  • The development and application of asystemic human error identification and remediation methodology

    Creator:
    Lee, Wei-Tau
    Abstract:
    This thesis describes a Systemic Vulnerability Identification and Remediation (SVIR) methodology that identifies human fallibilities and errors in complex technical processes, and recommends remediations for the errors, based on human factors principles and guidelines. The objectives of the research described in the thesis are the development of the methodology and...

  • Measuring Instrument Precision Estimation in Destructive Testing

    Creator:
    Sunil Raj, Sayooj
    Abstract:
    The variability introduced into measurements by a measuring instrument is referred to as measurement instrument precision. Experimental procedures and analysis methods exist when measurements are repeatable and can be repeated on the same item. However, when the measurements are destructive and repeated measurements are not possible, estimating measuring instrument precision...

  • Analysis and Comparison of Fixed-Size Lot and Fixed-Time Lot Batch Production Systems

    Creator:
    Tiwari, Prashant
    Abstract:
    In high volume automated discrete item batch production systems, the batches or lots are typically fixed quantity (i.e., size), with setups incurred between the different production lots. Processing times for the fixed-size lots are relatively constant when the workstation is operating however, random workstation disruptions cause variability in the lot...

  • The effect of feedstock composition on defect evolution in powder injection molded ceramic microarrays using simulations and experiments

    Creator:
    Laddha, Sachin
    Abstract:
    Micro Powder injection molding (μPIM) is a cost-effective technique for producing small, complex, precision parts in high volumes from ceramic and metal nanoparticles. This study focuses on research conducted on fabrication of Micro Ceramic Arrays (MCAs) parts using μPIM. MCAs are widely used as the major components and design features...
