• Ford Motors
    Aimdyn is using it’s GoSUM software to improve operation and fuel efficiency of advanced engines in collaboration with the Ford Motor Company.

    "GoSUM shows a unique efficiency in analyzing impact of uncertainty on system performance. This is why we are pursuing the application of the tool to models of our advanced engines." -Dr. Mrdjan Jankovic, Senior Technical Leader, Ford Research and Advanced Engineering
  • Heart Baroreflex System
    Aimdyn’s modeling expertise and software applied to complex models of human physiology are used to study interaction of physiology and behavioral aspects related to alcohol abuse in joint work with Rutgers University, sponsored by the National Institutes of Health.

    "GoSUM is helping us meet a major challenge in our human biobehavioral research by providing a cutting-edge research tool to probe into the complex interrelation of physiological and psychological systems that promote risk for problem alcohol and drug use." -Dr. Marsha Bates, Research Professor I of Psychology, Center of Alcohol Studies, Rutgers University; Associate Professor of Psychiatry, Robert Wood Johnson Medical School, UMDNJ
  • Deepwater Horizon Oil Spill
    Aimdyn worked with the Naval Research Laboratory in Stennis, Mississippi and developed sophisticated system analytics techniques to predict the extent oil spread in the Gulf of Mexico during the Deepwater Horizon Oil Spill in 2010.

    The results were published in the prestigious journal Science.
  • Maritime Industry
    Aimdyn software can be used for ship routing optimization, improving fuel efficiency, optimal search routing, and ship inspections.
