Oregon State University has conducted research in collaboration with TerraPower, LLC, to perform a top-down scaling analysis of an integrated test facility. The goal of this facility is to simulate transient and quasi-steady phenomena at a reduced scale, including steady-state operation, pump coastdown, natural circulation, reactor head heat transfer, and coolant stratification. To support this goal, this thesis presents the methodology and analysis by which approximate facility dimensions were generated. This analysis includes implementation of the hierarchical two-tiered scaling methodology, as outlined by the Nuclear Regulatory Commission and optimization through the general reduced gradient methodology. / Graduation date: 2013

In the introduction there is described a history of the post office. There is also outlined a current state and a future intention of Czech Post (Česká pošta s. p.). Further there is explained an issue of the formatting of the address side of postcards and writing. In another part there is a job description of the sorting machine SIEMENS IRV 3000 and also information on the location of this sorting machine at each collecting transport nodes. In the conclusion there is described a consideration to increase a number of appropriate mail pieces for the sorting machine.
