  • 100 Biodiesel Vector Technology and Fuel Dispensing Solution A CTECH Live Lab Pilot Project for the Implementation and Evaluation of the 100 Biodiesel Technology on Identified Equipment Within Cornells Fleet Operations
    100% Biodiesel Vector Technology and Fuel Dispensing Solution — A CTECH Live Lab Pilot Project for the Implementation and Evaluation of the 100% Biodiesel Technology on Identified Equipment Within Cornell’s Fleet Operations
    Brumberg, Gregory ;
    Li, Lawrence
    2021-07-02 | PDF
    In this study, researchers analyzed whether it was feasible for Cornell vehicles to use the Vector System (VS) by Optimus Technologies, a system that modifies diesel engine vehicles to run on biodiesel in addition to diesel in cold weather conditions. Biodiesel solidifies at a higher temperature than diesel, so to use biodiesel in the winter, the V ...
  • Effects of Service Life of Aluminized Steel Corrugated Pipe with Visible and Not Visible Coating Deficiencies within the Lock System
    Effects of Service Life of Aluminized Steel Corrugated Pipe with Visible and Not Visible Coating Deficiencies within the Lock System
    Al Yaarubi, Mohammed ;
    Aliofkhazraei, Mahmood
    2021-07-01 | PDF
    The electrochemical behavior of aluminized and galvanized steel is investigated to determine the corrosion performance of coating deficiencies generated within the lock-seams during the fabrication of aluminized and galvanized steel corrugated pipe. Electrochemical techniques and visual and profilometric analysis are used to assess the ability of t ...
  • Balanced Asphalt Concrete Mix Performance in Utah Phase V Field Evaluation for Intermediate and LowTemperature Cracking
    Balanced Asphalt Concrete Mix Performance in Utah. Phase V: Field Evaluation for Intermediate and Low-Temperature Cracking
    Romero, Pedro
    2021-07-01 | PDF
    A follow-up study was conducted in which the performance of five asphalt pavements was documented after three years of field service in Utah. Cores were taken at each pavement section and brought to the lab where they were cut and tested using the BBR, the IFIT, and the IDEAL CT. The respective performance indices from these tests were compared to ...
  • SelfCentering Bridge Bent for Accelerated Bridge Construction
    Self-Centering Bridge Bent for Accelerated Bridge Construction
    Pantelides, C. P. ;
    Thapa, Dipendra
    2021-07-01 | PDF
    Precast concrete construction has been proven to be very efficient in bridge engineering, especially in accelerated bridge construction (ABC), where precast concrete components are connected to save time and minimize disruption of traffic. Post-tensioned (PT) concrete structural elements when combined with energy dissipators (ED) create a hybrid sy ...
  • SelfCentering Bridge Bent for Accelerated Bridge Construction Research Brief
    Self-Centering Bridge Bent for Accelerated Bridge Construction [Research Brief]
    Pantelides, Chris P. ;
    Thapa, Dipendra
    2021-07-01 | PDF
    The research addresses a new hybrid bridge system for ABC in seismic regions. Researchers investigated the connection of precast concrete elements with unbonded post-tensioned bars and SLAs and their seismic performance. They constructed a precast concrete bridge bent consisting of two footings, two columns, and a cap beam (the entire assembly is c ...
  • Integrate Autonomous Delivery Vehicle into Sustainable Urban Logistics Planning and Optimization Economic and Environmental Evaluation
    Integrate Autonomous Delivery Vehicle into Sustainable Urban Logistics Planning and Optimization: Economic and Environmental Evaluation
    Kaisar, Evangelos I. ;
    Liu, Dan
    2021-07-01 | PDF
    The last mile problem of E-grocery Distribution comprises one of the most costly and highest polluting components of the supply chain in which companies deliver goods to end customers. To reduce transport cost and fuel emissions, a new element of ground-based delivery services, autonomous delivery vehicles (ADVs), is included in the E-grocery distr ...
  • The Sidekick Routing Paradigm for VMT Reduction and Improved Accessibility Research Brief
    The “Sidekick” Routing Paradigm for VMT Reduction and Improved Accessibility [Research Brief]
    Carlsson, John Gunnar
    2021-07-01 | PDF
    This project has combined tools from geospatial analysis, mathematical optimization theory, and computational geometry to study a routing paradigm that we call sidekick routing. A sidekick routing scheme is a logistical framework in which a large vehicle, such as a truck or van, serves as a mobile base for a fleet of small vehicles (the “sidekicks” ...

    2021-07-01 | PDF
    This report presents the data sources, descriptions, and file structures for computation of the economic competitiveness metrics to be reported annually as part of Action 6 of the California Sustainable Freight Action Plan. The report also includes instructions for computing the metrics and adding to the database as additional years become availabl ...
  • Applying Levelized Cost of Storage Methodology to UtilityScale SecondLife LithiumIon Battery Energy Storage Systems
    Applying Levelized Cost of Storage Methodology to Utility-Scale Second-Life Lithium-Ion Battery Energy Storage Systems
    Steckel, Tobiah ;
    Kendall, Alissa
    2021-07-01 | PDF
    The dramatic increase in electric vehicle (EV) sales has led to a rapid increase in deployed lithium-ion battery (LIB) capacity over the last decade. As EV batteries age and are retired from use in vehicles, they will require management. Second-life applications are often proposed as an environmentally and economically preferable management strateg ...

    The effective management and operation of existing freeway facilities has become a preferred approach to reduce traffic congestion. Weaving areas are characterized by frequent lane changes, which significantly reduce the capacity of the freeway system. These are common design elements on freeway facilities between an on ramp and off ramp with an au ...

    This project develops a method to incentivize taxis to travel to different parts of a city so that they sense data or pick up passengers in under-served areas. Taxis' natural movement generally leads to them concentrating in busy locations with many potential passengers. By incentivizing taxis to move towards less busy locations, one can even out t ...
