Modeling and Data Visualization Case Study
The middle of the 20th Century saw the rise of the use of nuclear power for the generation of electricity and the construction of dozens of nuclear power plants throughout the developed world. Following the high profile disasters of Three Mile Island and Chernobyl, there was very little growth, worldwide, of nuclear power, and the end of the century saw comparatively few new plants commissioned.
In what has been termed a Nuclear Renaissance, the first part of the 21st century has seen an increase in planning and construction of new facilities. That, combined with a workforce in the existing plants rapidly moving into retirement age, has created the need for a new generation of power plant operators.
While technology and plant design have changed during the intervening years, training has remained largely the same as it was in mid-century, with a reliance on printed mauals and PDF files. This re-birth of the industry, combined with the nuclear disaster at Fukushima, Japan have provided the impetus for newer, more effective and efficient methods of training personnel. Bridgeborn and its subsidiary, TriLink Systems have collaborated with L-3 Mapps, a leading global supplier of control and simulation solutions for power generation industries, to develop a visualization solution for L-3 Mapps' nuclear power simulators. Using the Bridgeworks™ 3D visualization platform, hundreds of data points, streamed from the simulator, are sampled five times per second and used to update, in real time, a 3D representation of the reactor and coolant system. This represents a number of advantages over more traditional training scenarios: at-a-glance understanding of both the overall state of the system, and subsystems for a number of process values (temperature, pressure, void fraction & enthalpy), gives the user a less abstract understanding of the system and function, allowing the user to visualize conditions and processes in areas that wouldn't be visible or accessible due to life threatening conditions within the reactor containment, and provides the ability to pinpoint what is affected by a particular condition.
Afghan Technical Vocational Institute
Education and Training Case Study
Bridgeborn developed a Training Delivery Platform™ (TDP) for the Afghan Technical Vocational Institute (ATVI). The Institute, funded partly by USAID and partly by commercial partners, was preparing courses and curricula to train students in the key sectors of horticulture, construction, information and communications technology and vehicle maintenance. Because of scarcity of both training materials and funding for staff, alternative methods for training delivery were needed to accomplish educational goals. Bridgeborn developed automotive repair courseware based on its Bridgeworks™ platform, a 3D interactive, web based framework. The use of Bridgeworks™ provided multiple benefits over more traditional training methods.
Because equipment was limited, not all students could have ready access to vehicle systems and components. The Bridgeworks™ based 3D lessons allowed all students to access the material, frequently, and due to the fact that lessons were web based, at their convenience.
Students could see functioning components from angles and views that would have been impossible in real life. This allowed the student to visualize complex concepts, such as the inner workings of an internal combustion engine or an entire automotive power train in one interactive, animated view. These views represented working models of a 4 cylinder diesel engine, its four stroke internal combustion cycle, brake assembly and drive train. While not, strictly speaking, "hands-on" experience, the models provided valuable exposure to the structure and components and their functioning; with the added benefit of being universally and constantly available. Additionally, components would assemble and disassemble, complete with 3D labels at the push of a button.
Because students could study independently and at their own pace, less direct instructor time was necessary to allow the students to gain a thorough understanding of the material. The animated 3D features of the lessons made the components and processes virtually self-explanatory.
Subsequently, time spent with actual components was used to greater effect due to the fact the students had already gained a familiarity through the Bridgeworks™ modules.
Emirates Simulation Academy
Education and Training Case Study
As part of an initiative to engage its citizens in the development and maintenance of critical infrastructure, in this case power and energy, The United Arab Emirates, entrusted the founding of the Emirates Simulation Academy to the President of TriLink Systems,* Hal Paris. Mr. Paris was responsible for developing the curriculum and courseware as well as securing operational funding.
In support of that effort, Bridgeborn developed and deployed an online Training Delivery Platform (TDP). The TDP consists of a Learning/Content Management system complete with student tracking, grading, and content delivery. Interactive, 3D training tools were developed for system level (i.e. gas turbine) and component level (i.e. valves, pumps) visualizations. The TDP also integrated with high fidelity simulations and represented them through an interactive, 3D user interface. The overarching framework allows for extensibility to include additional content, new systems, integration with other simulators and reuse in 70+ languages.

Education and Training Case Study
Georgetown University Medical School was encountering dramatic decreases in the availability (and increases in cost) of cadavers for their extensive and comprehensive “hands on” training of human anatomy. The client needed to fill this void with a training solution that could support its existing curriculum.
Working in conjunction with leading, tenured professors and doctors at Georgetown, Bridgeborn created content that could be delivered via the web or used in the classroom as part of their curriculum. The training solution used Bridgeworks™ to power high fidelity, photo-realistic 3D renderings of the lower arm and hand. Using effects such as animations and dissolves, the deliverable taught students complex motions and movements (movements that would have been under the skin of a live subject and therefore, hidden) including pronation of the arm and flexion and extension of the hand. Interaction between the web page and the 3D scene allowed students to click on any term and have it highlight the appropriate portion of the 3D scene.
Bridgeborn's deliverable proved to be a cost effective way to supplement training on scarce and expensive cadavers. The interactive 3D scene was portable, could be infinitely replicated, and could demonstrate complex motions and movements that had historically proved to be difficult to teach or understand through text books and static, 2D content.
