Assessing hydraulic conditions through Francis turbines using an autonomous sensor device

Renewable Energy (2016)

Tao Fu Zhiqun Deng Joanne P. Duncan Daqing Zhou Thomas J. Carlson

Fish can be injured or killed during turbine passage. This paper reports the first in-situ evaluation of hydraulic conditions that fish experienced during passage through Francis turbines using an autonomous sensor device at Arrowrock, Cougar, and Detroit Dams. Among different turbine passage regions, most of the severe events occurred in the stay vane/wicket gate and the runner regions. In the stay vane/wicket gate region, almost all severe events were collisions. In the runner region, both severe collisions and severe shear events occurred. At Cougar Dam, at least 50% fewer releases experienced severe collisions in the runner region operating at peak efficiency than at the minimum and maximum opening, indicating the wicket gate opening could affect hydraulic conditions in the runner region. A higher percentage of releases experienced severe events in the runner region when passing through the Francis turbines than through an advanced hydropower Kaplan turbine (AHT) at Wanapum Dam. The nadir pressures of the three Francis turbines were more than 50% lower than those of the AHT. The three Francis turbines had much higher magnitudes and rates of pressure change than the AHT. This study provides critical information on hydraulic conditions and fish passage information of Francis turbines, which can help guide future laboratory studies of fish passing through Francis turbine, design fish-friendly turbines, and optimize the operation of existing turbines for better fish passage conditions.

Hybrid neural predictor/stochastic trajectory models for Chinese speech recognition

Electronics Letters (1999)

Chengwei Huang Ma Tao Fu Lü

Based on stochastic trajectory models (STMs) and neural networks, a new approach to Chinese speech recognition, the hybrid neural predictor/stochastic trajectory model (STM/NP), is proposed. STM/NP makes full use of the advantages of STMs and the characteristics of the NN. The experimental results demonstrate the efficiency of the STM/NP approach.

Acoustic Telemetry Evaluation of Juvenile Salmonid Passage and Survival Proportions at John Day Dam, 2009

Mark A. Weiland Gene R. Ploskey James S. Hughes Zhiqun Deng Tao Fu

The overall purpose of the acoustic telemetry study at JDA during 2009 was to determine the best configuration and operation for JDA prior to conducting BiOp performance standard tests. The primary objective was to determine the best operation between 30% and 40% spill treatments. Route-specific and JDA to TDA forebay survival estimates, passage distribution, and timing/behavior metrics were used for comparison of 30% to a 40% spill treatments. A secondary objective was to evaluate the performance of TSWs installed in spill bays 15 and 16 and to estimate fish survival rates and passage efficiencies under 30% and 40% spill-discharge treatments each season.

Survival and Passage of Yearling Chinook Salmon and Steelhead at The Dalles Dam, Spring 2011 - FINAL REPORT

Gary E. Johnson Matthew J. Hennen Shon A. Zimmerman George W. Batten Scott M. Carpenter

The study reported herein was conducted by the Pacific Northwest National Laboratory (PNNL) and the University of Washington (UW) for the U.S. Army Corps of Engineers, Portland District (USACE). The PNNL and UW project managers were Drs. Thomas J. Carlson and John R. Skalski, respectively. The USACE technical lead was Mr. Brad Eppard. The study was designed to estimate dam passage survival and other performance measures at The Dalles Dam as stipulated by the 2008 Federal Columbia River Power System Biological Opinion (BiOp) and the 2008 Columbia Basin Fish Accords. The study is being documented in two types of reports: compliance and technical. A compliance report is delivered within 6 months of the completion of the field season and focuses on results of the performance metrics outlined in the 2008 BiOp and Fish Accords. A technical report is produced within the 18 months after field work, providing comprehensive documentation of a given study and results on route-specific survival estimates and fish passage distributions, which are not included in compliance reports. This technical report concerns the 2011 acoustic telemetry study at The Dalles Dam.

Several classes of 0-APN power functions over $\mathbb{F}_{2^n}$

arXiv (Cornell University) (2022)

Tao Fu Haode Yan

Recently, the investigation of Partially APN functions has attracted a lot of attention. In this paper, with the help of resultant elimination and MAGMA, we propose several new infinite classes of 0-APN power functions over $\mathbb{F}_{2^{n}}$. By the main result in [4], these $0$-APN power functions are CCZ-inequivalent to the known ones. Moreover, these infinite classes of 0-APN power functions can explain some exponents for $1\leq n\leq11$ which are not yet ``explained" in the tables of Budaghyan et al. [3].

Multiple Weibull Statistical Model of Random Censored Data of NC Machine Tools and Optimal Estimation of Parameters

Applied Mechanics and Materials (2014)

Tao Fu Da Zhen Wang Qin Zhong Gong

According to the truncation feature of NC machine tools, this paper adopts Johnson rank adjustment method to deal with censored data, finding the distribution model of time between failures. At the same time, in order to increase the accuracy of parameter estimation of reliability data distribution model of NC machine tools, and to avoid the shortcoming that conventional optimization algorithms is difficult to get global optimal solution due to the influence of iteration initial value, this paper uses particle swarm optimization to solve the parameter of weibull mixture model. The result shows that particle swarm optimization can balance solution efficiency and convergence performance, it is not only feasible to estimate the parameter of mixture weibull distribution, but also to get more accurate results.
