  • Toward the estimation of errors in cloud cover derived by threshold methods

    Creator:
    Chang, Fu-Lung
    Abstract:
    The accurate determination of cloud cover amount is important for characterizing the role of cloud feedbacks in the climate system. Clouds have a large influence on the climate system through their effect on the earth's radiation budget. As indicated by the NASA Earth Radiation Budget Experiment (ERBE), the change in...

  • Properties of low-level marine clouds as deduced from advanced very high resolution radiometer satellite observations

    Creator:
    Chang, Fu-Lung
    Abstract:
    A radiation model was developed for retrieving cloud visible optical depth, droplet effective radius, and cloud top emission temperature using AVHRR satellite observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity of the retrieved properties to various approximations often employed in such retrievals. Droplet...

  • Relationships between Marine Stratus Cloud Optical Depth and Temperature: Inferences from AVHRR Observations

    Creator:
    Chang, Fu-Lung and Coakley, James A., Jr.
    Abstract:
    Studies using International Satellite Cloud Climatology Project (ISCCP) data have reported decreases in cloud optical depth with increasing temperature, thereby suggesting a positive feedback in cloud optical depth as climate warms. The negative cloud optical depth and temperature relationships are questioned because ISCCP employs threshold assumptions to identify cloudy pixels...

  • Synthesis, characterization and deposition of dendrimers using a continuous flow microreactor

    Creator:
    Liu, Shuhong
    Abstract:
    Dendrimers are nanoscale macromolecules that have highly branched, core-shell structures. Higher generation dendrimers have close-packed peripheral functional groups and a hollow interior. The chemistry of the core and the terminal functionalities can be tailored according to the specific application. These structural characteristics provide room for the design of dendrimers to...

  • Analysis of ras gene mutations in rainbow trout tumors

    Creator:
    Chang, Yung-jin
    Abstract:
    For ras gene mutation analysis in the rainbow trout (Oncorhynchus mykiss) model system, a partial trout ras sequence was identified using the polymerase chain reaction (PCR). Two synthetic oligonucleotides based on rat K-ras gene sequence were used as primers for the PCR procedure. A 90 base pair (bp) sequence, referred...

    Creator:
    Chang, Yung-jin
    Abstract:
    DNA from the human squamous carcinoma cell line, SK-MES-1, and the plasmids, pUC EJ6.6 containing H-ras oncogene, pSVc-mycl containing cellular myc gene, pNRSac containing N-ras oncogene, pBR SV containing SV40 virus DNA, pSV2-neu containing neu oncogene and pSV2-neo containing neomycin resistant gene were used to transform Balb serum-free derived mouse...

  • Application of pattern recognition to a human behavior problem

    Creator:
    Chang, Chia-hao
    Abstract:
    Pattern recognition techniques and their application to a consumer behavior study are presented. The Local Majority Method (LOMAME) utilizes a set of prototypes and corrective factors which undergo a training cycle before being utilized as pattern classifiers. Its advantages over the Minimum-Distance Method and the Fix and Hodges Method are...

  • Cryopreservation of in vitro-grown apical meristems

    Creator:
    Chang, Yongjian
    Abstract:
    Alternating temperature (22°C / -1°C) pretreatments were effective for increasing cold hardiness and recovery of cryopreserved meristems. Combining low temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the time required for optimal cold hardiness of meristems. Desiccation tolerance was directly correlated with increased cold hardiness and recovery of...
