    • CS28: Inner and Outer Race Defect Detection and Monitoring 
      Yu, John; Wang, Carl Feng; Yuan, Mingfeng; Péton, Nicolas; Guan, Xiaodong; Ye, Mingxing (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2021)
      Accelerometers were used to measure vibration of the input shaftusing an on-line remote monitoring system Though the vibrationamplitudes were below the acceptable limit for over a year period,two bearing damages were thought ...
    • CST05 - Fluid-Film Bearing Damage Detection Based on Vibration Data� 
      Yu, John; Peton, Nicolas (Turbomachinery Laboratory; Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      This case occurred during startup after outage on a steam turbine generator. Vibration reached over full scale of 20 mil pp at generator drive end bearing and therefore tripped the unit. The major vibration component that ...
    • Detection of Misalignment from Vibration Data 
      Yu, John; Péton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      On a boiler feed pump driven by a motor running close to 3600 rpm, a horizontal misalignment issue was suspected by examining orbit plots besides shaft centerline plots. The follow-up inspection did uncover large parallel ...
    • Development, genetic mapping and QTL association of cotton PHYA, PHYB, and HY5-specific CAPS and dCAPS markers 
      Kushanov, Fakhriddin; Pepper, Alan; Yu, John; Buriev, Zabardast; Shermatov, Shukhrat; Saha, Sukumar; Ulloa, Mauricio; Jenkins, Johnie; Abdukarimov, Abdusattor; Abdurakhmonov, Ibrokhim (BMC Genetics, 2016)
    • High Vibration Due to Steam Turbine Deposits 
      Yu, John; Zhou, Tony Wei; Lin, Haibo; Wang, Carl Feng; Peton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This presentation provides a case study how to correctly deal with increased vibration on a steam turbine that drives a compressor. After the machine had not operated for a week, vibration level increased 5 times during ...
    • Pelletizer Motor Bearing Damage Detection Based on Vibration Data 
      Yu, John; Feng Wang, Carl; Wei Zhou, Tony; Lin, Haibo; Quan, Ju; Peton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • RNA Interference for Functional Genomics and Improvement of Cotton (Gossypium sp.) 
      Abdurakhmonov, Ibrokhim; Ayubov, Mirzakamol; Ubaydullaeva, Khurshida; Buriev, Zabardast; Shermatov, Shukhrat; Ruziboev, Haydarali; Shapulatov, Umid; Saha, Sukumar; Ulloa, Mauricio; Yu, John; Percy, Richard; Devor, Eric; Sharma, Govind; Sripathi, Venkateswara; Kumpatla, Siva; Alexander van der Krol; Kater, Hake; Khamidov, Khakimdjan; Salikhov, Shavkat; Jenkins, Johnie; Abdukarimov, Abdusattor; Pepper, Alan (Frontiers in Plant Science, 2016)
    • TAL effector driven induction of a SWEET gene confers susceptibility to bacterial blight of cotton 
      Cox, Kevin; Meng, Fanhong; Wilkins, Katherine; Li, Fangjun; Wang, Ping; Booher, Nicholas; Carpenter, Sara; Chen, Li-Qing; Zheng, Hui; Gao, Xiquan; Zheng, Yi; Fei, Zhangjun; Yu, John; Isakeit, Thomas; Wheeler, Terry; Frommer, Wolf; He, Ping; Bogdanove, Adam; Shan, Libo (Nature Communications, 2017)
    • Vibration issue on Compressor in a Nitric Acid Plant (Part 2) 
      Wright, Gary; Peton, Nicolas; Drygin, Sergey; Yu, John; Davies, Dave (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2022)
      “Part 1 of the case history for this return to service follows on from the 2021 ATPS “ presentation which covered off the Expander related issue (labyrinth seal rubs) preventing the NAP 2 plant from successfully re ...
