The United States Navy Meteorology and Oceanography (METOC) community routes ships for weather evasion using advanced meteorological modeling and satellite data, but lacks a tool to enable fewer ship routers to make better routing decisions faster. Limited resources and rising costs are impacting the frequency and duration of current naval operations. The Commander, Naval Meteorology and Oceanography Command has ordered the community to find efficiencies and automation possibilities in order to meet lower manning levels, reduce waste, and increase savings. Outside of the Navy, Ocean Systems Incorporated in Alameda, CA developed the Ship Tracking and Routing System (STARS) software package to calculate optimum sea routes based on weather model data. However, METOC ship routers are reluctant to adopt this complex software. To help solve this, we modeled Optimum Track Ship Routing (OTSR) for U.S. Navy warships using a network graph of the Western Pacific Ocean. A binary heap version of Dijkstra's algorithm determines the optimum route given model generated wind and seas input. We test the model against recent weather data to verify the model's performance, and to historical divert route recommendations in order to validate against routes developed by OTSR personnel.

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / As the code length is increasing, the search of optimum group sync codes will be more and more difficult, even impossible. This paper gives the searching method of quasi-optimum group sync codes on the small subset of PN sequences -- CVT-TAIL SEARCHING METHOD and PREFIX-SUFFIX SEARCHING METHOD. We have searched out quasi-optimum group sync codes for their lengths N=32-63 by this method and compared them with corresponding optimum group sync codes for their lengths N=32-54. They are very approximative. The total searching time is only several seconds. This method may solves the problems among error sync probability, code length and searching time. So, it is a good and practicable searching method for long code.

Author: Nadzeya Laurentsyeva Title: Monetary Union of Belarus and Russia - Analysis of Possible Costs for the Belarusian Economy Abstract The thesis analyses alignment of the Belarusian and Russian economies with the aim to infer on costs of the possible monetary union for Belarus. Having estimated a structural vector autoregression model with long-run restrictions, we conclude that the economies have shared common supply and external demand shocks, but other temporary fluctuations have been, in large, asymmetric. Structural discrepancies (as proven by the qualitative analysis) and differences in the monetary policy foci and transmission (as illustrated by the estimation results of Taylor rules and a monetary vector autoregression model) could account for increasing misalignment since 2010. In terms of the welfare costs for Belarus (evaluated with a New Keynesian dynamic stochastic general equilibrium model), the monetary union can be considered preferable to the current monetary policy of the National bank of the Republic of Belarus, while being inferior to the hypothetical inflation targeting regime. The welfare gap between the two arrangements reduces, if stronger domestic price flexibility and higher synchronization of productivity shocks can be assumed.

Matrix acidizing is commonly used to stimulate wells in carbonate reservoirs. Large amounts of lab tests indicate an optimum acid interstitial velocity (Vi-opt, injection rate over flow area and porosity) exists, which results in the minimum volume of acid required for wormhole propagation and best stimulation results. Previous tests showed that the Vi-opt increased with increasing core length, but it is not clear if the Vi-opt can be independent of the core length when the core length reaches a certain value. In this work, a series of core flood experiments with different core lengths was carried out to determine the Vi-opt. Results showed that the Vi-opt became a constant when the core length reached a certain length. The finding of this study can guide lab researchers to use proper core lengths when determining the Vi-opt.
