    Notes: A multichannel far-infrared (FIR) hydrogen cyanide (HCN) laser interferometer was developed to measure plasma electron density profile on the HT-6M tokamak. The structure of the seven-channel FIR laser interferometer is described. The laser source used in the interferometer was a continuous-wave glow discharge HCN laser with a cavity length of 3.4 m and power output of about 100 mW at 337 μm. The detection sensitivity was 1/15 fringe with a temporal resolution of 0.1 ms. Experimental results were measured by the seven-channel FIR HCN laser interferometer with edge Ohmic heating, a pumping limiter, and ion cyclotron resonant heating on the HT-6M tokamak are reported. © 1995 American Institute of Physics.

    Electroluminescence of a novel terbium complex (1998)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 72 (1998), S. 2217-2219 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We describe efficient electroluminescence from a terbium complex, tris-(1-phenyl-3-methyl-4isobutyryl-5-pyrozolone)-bis(triphenyl phosphine oxide) terbium (PTT). The green-emitting material possesses much higher photoluminescence efficiency compared to the commonly used green light emitter, 8-hydroxyquinoline aluminum (ALQ). The rarely observed emission from the hole transport layer, N, N′-bis (3-methylphenyl)- N, N′-diphenyl-benzidine (TPD) of the device ITO/TPD/PTT/Al proves that PTT also is a good electron transporting material. The ITO/TPD/PTT/ALQ/Al device shows luminance up to 920 cd/m2 at a drive voltage of 18 V and a luminous efficiency of 0.51 lm/W at a current density of 0.70 mA/cm2, which are up to now the highest among devices using rare-earth complex materials as emitters. © 1998 American Institute of Physics.

    APPLICATION OF FUZZY SETS AND NEURAL NETWORKS IN SENSORY ANALYSIS (1999)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 14 (1999), S. 0 
    Details
    ISSN: 1745-459X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: This paper describes an initial but fundamental attempt to lay some groundwork for a fuzzy-set-based paradigm for sensory analysis and to demonstrate how fuzzy set and neural network techniques may lead to a natural way for sensory data interpretation. Sensory scales are described as fuzzy sets, sensory attributes as fuzzy variables, and sensory responses as sample membership grades. Multi-judge responses are formulated as a fuzzy membership vector or fuzzy histogram of response, which gives an overall panel response free of the unverifiable assumptions implied in conventional approaches. Neural networks are used to provide an effective tool for modeling and analysis of sensory responses in their naturally fuzzy and complex forms. A maximum method of defuzzification is proposed to give a crisp grade of the majority opinion. Two applications in meat quality evaluation are used to demonstrate the use of the paradigm and procedure. It is hoped that this work will bring up some new ideas and generate interest in research on application of fuzzy sets and neural networks in sensory analysis.

    Mechanically Recovered Neck Bone Lean and Ascorbic Acid Improve Color Stability of Ground Beef Patties (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 61 (1996), S. 0 
    Details
    ISSN: 1750-3841

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Ground beef patties at two ascorbic acid (Asc) levels (0 and 1,000 ppm) and three mechanically recovered neck bone lean (MRNL) levels (0, 15 and 30%) were analyzed for percentage surface metmyoglobin (metMb) and HunterLab L* and a* values over 6 days of retail display. Data were collected for two replications. Patties made with Asc had less (P 〈 0.01) surface metMb than patties made without Asc on days 1-4 of retail display. Ascorbic acid and MRNL acted synergistically to improve surface color. Patties made with Asc showed a linear decrease (P 〈 0.05) in surface metMb as MRNL level increased from 0 to 30%. Patties made without Asc showed no change in surface metMb as MRNL level increased.

    Beef Marbling and Color Score Determination by Image Processing (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 61 (1996), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Sixty steaks with various degrees of marbling and color were subjected to sensory evaluation and image processing. Marbling and color scores were assigned to each steak with USDA marbling score cards and a lean color guide. Images were recorded for each steak under the same conditions as used for sensory analysis. Steak images were processed for color and marbling characteristics. Image processing effectively predicted the lean color (R2= 0.86) and marbling scores (R2= 0.84). Image processing was an effective tool for determining USDA quality attributes of fresh meat.

    A factor analysis approach to measure the biased effects of retail fruit juice advertising (1995)
    Springer
    Empirical economics 20 (1995), S. 93-107 
    Details
    ISSN: 1435-8921
    Keywords: C53 ; D12 ; M37
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract This study presents a structural factor analysis approach to measure the impact of advertising on consumer demand. It is assumed that advertising affects the latent perception of consumers, which in turn influences their purchasing behavior. This study investigates the relationship between consumer purchases and retail store advertising (i.e., newspaper advertising, in-store display, and point-of-purchase display) of three fruit juices using an extended Rotterdam model. The results show that the demand for orange juice and grapefruit juice was affected by their own advertising, while the demand for apple juice was only affected by advertising of competitive juices.

    A CCD imaging spectrograph in the improved solar tower of Nanjing University (1995)
    Springer
    Solar physics 159 (1995), S. 127-135 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Since 1992 the solar tower telescope of Nanjing University (118°51′ E, 32°03′ N) as well as its multichannel solar spectrograph, originally established in 1982, have been reconstructed and a two-channel imaging spectrograph has been operated successfully. The apertures of the coelostat and the secondary mirror are both 60 cm. The spherical objective mirror, having an aperture of 43 cm and a focal length of 2170 cm, produces a solar image of 20 cm diameter. Two auxiliary telescopes using a small fraction of the coelostat's aperture were set up for guiding and Hα monochromatic monitoring. A multichannel spectrograph can be operated in six wavebands simultaneously. A CCD imaging spectrograph can be used for data acquisition at Hα and Caii K line wavebands automatically and simultaneously. The instrument consists of two CCD cameras, an image processor (SR-151), a personal computer, and a mechanical scanning device. The principal characteristics of the instruments are described. Some observational results are presented as examples.

    Discrete differences between strains of different Rhizobium spp. for competitive nodule occupancy on beans (1995)
    Springer
    World journal of microbiology and biotechnology 11 (1995), S. 681-682 
    Details
    ISSN: 1573-0972
    Keywords: Melanin pigment ; nodulation competitiveness ; Rhizobium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Rhizobium etli strain TAL182 and R. leguminosarum bv phaseoli strain 8002, both of which produce melanin pigment, were tested for their nodulation competitiveness on beans by paired inoculation with two strains which do not produce melanin: R. tropici strain CIAT899 and Rhizobium sp. strain TAL1145. An assay was developed to distinguish nodules formed by the melanin-producing and non-producing strains. Strain TAL182 had discrete competitive superiority over CIAT899 and TAL1145 for nodulation of beans. Nodulation competitiveness was not correlated with the ability to produce melanin pigment or the host range of the Rhizobium strains tested.

    Notes: Abstract The liquid thermal conductivity of mixtures of HFC-32/125 and HFC-32/134a was measured using the transient hot-wire apparatus in the temperature ranges from 213 to 293 K and from 193 to 313 K, respectively, in the pressure range from 2 to 30 MPa and with HFC-32 mass fractions of 0.249, 0.500, and 0.750 for each system. The uncertainty of the thermal conductivity was estimated to be ±0.7%. For practical applications, the thermal conductivity data for the two mixtures were represented by a polynomial in temperature, pressure, and mass fraction of HFC-32 with a standard deviation of 1.0%.

    Notes: Abstract The liquid thermal conductivities of the CFC alternatives, HFC-125, and HCFC-141b measured by a transient hot-wire apparatus with one bare platinum wire are reported in the temperature ranges from 193 to 333 K (HFC-125, CHF2, CF3) and from 193 to 393 K (HCFC-141b,CCI2F-CF3), in the pressure ranges from 2 to 30 MPa (HFC-125) and from 0.1 to 30 MPa (HCFC-141b), respectively. The results have been estimated to have an accurancy of ±0.5%. The liquid thermal conductives obtained have been correlated by a polynomial of temperature and pressure which can represent the experimental results within the standard deviations of 0.49% for HFC-125 and 0.46% for HCFC-141b, respectively.
