  • Finite Element Analysis of TA15 Titanium Alloy Beam Hammer Forging Forming at Different Temperatures
    Advanced Materials Research, 2011
    Co-Authors: Ying Tong
    Abstract:

    The hammer forging forming process of TA15 titanium alloy girder is taken as an example on this study. When girder were formed at different Original Temperature as 850 °C、900 °Cand 950 °C, the needed hammering times and each hammer’s stroke and varieties of damage factor were researched respectively based on software Deform. By simulation analysis, the needed hammering times is 7 times, 5 times and 4 times in order, and the damage factor which dangerous place located at the right top fillet of girder reached the highest point at about 86mm stroke ,and the Original Temperature 950 °C gave the best answer. The results are significant theoretical foundation for the practical production and study of TA15 titanium alloy.

  • On Source Coding for Distributed Temperature Sensing with Shift-Invariant Geometries
    IEEE Transactions on Communications, 2011
    Co-Authors: Baltasar Beferull-lozano, R L Konsbruck
    Abstract:

    We study the source coding problem in sensor networks deployed to monitor the evolution of spatio-temporal Temperature distributions. The sensors sample the Temperature field, quantize the samples and transmit the encoded samples through digital channels to some central unit, which computes an estimate of the Original Temperature field. Our analysis is based on the heat kernel's spectral properties, which are induced by the physics of heat diffusion. We determine rate distortion functions for various source coding schemes. In particular, we compare centralized coding, independent coding, Berger-Tung coding, and predictive quantization.

  • heat shock responsive genes identified and validated in atlantic cod gadus morhua liver head kidney and skeletal muscle using genomic techniques
    BMC Genomics, 2010
    Co-Authors: Tiago S Hori, Kurt A Gamperl, Luis O B Afonso, Stewart C Johnson, Sophie Hubert, Jennifer Kimball, Sharen Bowman, Matthew L Rise
    Abstract:

    Background Daily and seasonal changes in Temperature are challenges that fish within aquaculture settings cannot completely avoid, and are known to elicit complex organismal and cellular stress responses. We conducted a large-scale gene discovery and transcript expression study in order to better understand the genes that are potentially involved in the physiological and cellular aspects of stress caused by heat-shock. We used suppression subtractive hybridization (SSH) cDNA library construction and characterization to identify transcripts that were dysregulated by heat-shock in liver, skeletal muscle and head kidney of Atlantic cod. These tissues were selected due to their roles in metabolic regulation, locomotion and growth, and immune function, respectively. Fish were exposed for 3 hours to an 8°C elevation in Temperature, and then allowed to recover for 24 hours at the Original Temperature (i.e. 10°C). Tissue samples obtained before heat-shock (BHS), at the cessation of heat-shock (CS), and 3, 12, and 24 hours after the cessation of heat-shock (ACS), were used for reciprocal SSH library construction and quantitative reverse transcription - polymerase chain reaction (QPCR) analysis of gene expression using samples from a group that was transferred but not heat-shocked (CT) as controls.
