By comparison with conventional hydrostatic transmission, its power matches load well because it is adjusted by servo system. By comparison with secondary adjusting system being applied in industry newly, HESTS not only adjusts operation mechanism to match the system output and load well, but also adjusts engine or hydraulic pump, and manipulates the direction of power flow inputing or outputing the Energy Storage Unit actively. Therefore, HESTS can get energy of whole system matched well, increase the efficiency of system and performance of main machine. First, a HESTS applied in vehicle was designed.

Low level radwaste disposal problems are complex. Many important issue, such as radionuclide migration in the geosphere, must be carefully evaluated before making decision. This project will explore the use of a hydrogeological decision support system for solving these complex problems. The system will integrate hydrogeological analysis tools, geographic information system, mathematical models, stochastic and statistic methods, graphical interface, and decision system. By using the system, it is expected that many different alternatives can be efficiently analyzed and evaluated, and results can be presented much more effective to decision makers, while compared with the conventional presentation. Basing on the prototype system developed in the last two years, this project will integrate more analysis tools and improve the functions of the system.
