Impact of Clocking on the Aero-Therm.d.namics of a Second Stator tested in a One and a Half Stage Hp Turbine

Journal of Thermal Science 2008年第2期17卷 97-110页

作者： N.Billiard G.paniagua R.dénos Turbomachinery and propulsion department von Karman Institute for Fluid dynamics

This paper focuses on the experimental investigation of the time-averaged and time-accurate aero- therm.d.namics of a second stator tested in a 1.5 stage high-pressure turbine. The effect of clocking on aerodynamic and heat transfer are investigated. Tests are perform.d.under engine representative conditions in the VKI compression tube CT3. The test program includes four different clocking positions, i.e. relative pitch-wise positions between the fh-st and the second stator. probes located upstream and downstream of the second stator provide the therm.d.namic conditions of the flow field. On the second stator airfoil, measurements are taken around the blade profile at 15, 50 and 85% span with pressure sensors and thin-film gauges. Both time-averaged and time-resolved aspects of the flow field are addressed. Regarding the time-averaged results, clocking effects are mainly observed within the leading edge region of the second stator, the largest effects being observed at 15% span. The surface static pressure distribution is changed locally, hence affecting the overall airfoil performance. For one clocking position, the thermal load of the airfoil is noticeably reduced. pressure fluctuations are attributed to the passage of the up- stream transonic rotor and its associated pressure gradients. The pattern of these fluctuations changes noticeably as a function of docking. The time-resolved variations of heat flux and static pressure are analyzed together showing that the major effect is due to a potential interaction. The time-resolved pressure distribution integrated along the second stator surface yields the unsteady forces on the vane. The magnitude of the unsteady force is very dependent on the clocking position.

Bayesian Approach to Ranking and Selection for a Binary measurement System

Open Journal of Statistics 2019年第4期9卷 436-444页

作者： mark Eschmann James d. Stamey phil d. Young dean m. Young department of Statistical Science Waco TX USA department of Statistical Science Baylor University Waco TX USA department of Information Systems Baylor University Waco TX USA department of Statistical Science Baylor University Waco TX USA

Binary measurement systems that classify parts as either pass or fail are widely used. Inspectors or inspection systems are often subject to error. The error rates are unlikely to be identical across inspectors. We propose a random effects Bayesian approach to m.d.l the error probabilities and overall conforming rate. We also introduce a feature-subset selection procedure to determine the best inspector in terms of overall classification accuracy. We provide simulation studies that demonstrate the viability of our proposed estimation ranking and subset-selection methods and apply the methods to a real data set.

多倍体小麦中的二倍体化染色体配对由几个有着主要和次要作用的ph（部分同源配对）基因控制。在这些基因缺失或被来自于其它物种的基因（ph＇基因）所抑制时都会出现部分同源配对。把拟斯卑尔脱小麦（Triticumspeltoides即Angilopsspeltoides）的ph＇基因导入了普通小麦（***），并在此基础上进一步分析了被导入的成对ph＇和独立ph＇基因的表现。因ph＇基因对小麦的ph基因表现上位，在杂种F1代中小麦与外源染色体发生了部分同源配对。利用ph＇基因无性系，证实了小麦和簇毛麦（Haynaldiavillosa）染色体间的部分同源配对。由于在杂种F1代中出现了部分同源配对，并且不需要细胞遗传学操作，因此ph＇基因无性系可能是一个快速有效地向小麦导入外源基因的通用工具。

plasma polymerized acetylene deposition using a return corona enhanced plasma reactor

plasma Science and Technology 2017年第8期19卷 90-96页

作者： Rokibul ISLAm Shuzheng XIE Karl R ENGLUNd patrick d pEdROW School of Electrical Engineering and Computer Science Washington State University Composite materials and Engineering Center Washington State University

A corona based weakly ionized plasma source was developed to deposit plasma polymerized acetylene coating at atmospheric pressure. The plasma source included a distinctive point-topoint geometry consisting of an array of high voltage needles and an array of protrusions placed over a grounded screen. The geometry facilitated various corona discharge m.d.s that included return corona to contribute plasma polymerized acetylene deposition downstream from the corona section. Scanning probe techniques were used to investigate deposition on both the leading surface and the trailing surface of substrates. deposition was initiated as distinct nodules that merged to form a thin plasma polymerized coating.

pollination networks on islands are often characterized by less complexity than comparable continental environments(Olesen and Jordano 2002).Furthermore,they sometimes include novel generalist-feeding nonspecialist pollinators,including birds in particular(e.g.,Olesen 1985 and references therein).This ecological process has been commonly interpreted in a context of depauperation of insular faunas and interaction release(Traveset et al.2015).
