The helium resonance line at 584 Å has been observed with the UltraViolet Imaging Spectrograph (UVIS) Extreme Ultraviolet channel during the flyby of Venus by Cassini at a period of high solar activity. The brightness was measured along the disk from the morning terminator up to the bright limb near local noon. The mean disk intensity was ˜320 R, reaching ˜700 R at the bright limb. These values are slightly higher than those determined from previous observations. The sensitivity of the 584 Å intensity to the helium abundance is analyzed using recent cross-sections and solar irradiance measurements at 584 Å. The intensity distribution along the UVIS footprint on the disk is best reproduced using the EUVAC solar flux model and the helium density distribution from the VTS3 empirical model. It corresponds to a helium density of 8×10[SUP]6[/SUP] cm[SUP]-3[/SUP] at the level of where the CO[SUB]2[/SUB] is 2×10[SUP]10[/SUP] cm[SUP]-3[/SUP]. [less ▲]

When YBCO single domains are subjected to a variable magnetic field, the motion of vortices may give rise to a significant temperature increase and a degradation of the superconducting properties. We have experimentally investigated such effects in bulk melt-processed YBCO single domains. Several temperature sensors, a pick-up coil and two Hall probes were placed against the surface of a monolithic bulk YBCO pellet. Data were simultaneously recorded during the application of ac magnetic fields of various amplitudes, either with or without a pre-existing dc trapped flux. The measurement results agree well with to those obtained by numerical modeling. It was also found that a superimposed dc magnetic moment reduces the temperature increase caused by the ac magnetic field. (C) 2003 IEEE. [less ▲]

Measuring Brand Image Perception and Changes in Brand Image Perception wth Brand Concept Maps - Capturing Strength, Uniqueness and Favourability of Brand Associations in Different Contexts

Recently, authors have emphasized the differences between brand images held by different individuals depending on the perception, the experience with the brand and the types of contacts with the company. This finding is in sharp contrast with the conventional view recommending consistency and coherence in all the company’s actions. This research tradition has been called the consumer-focused view. Therefore, the author emphasized several academic motivations to develop research on brand image measurement on a consumer level. First, considering that different images are socially constructed constellations of meanings, established between marketers and consumers, with implications for both parties as well as for the marketplace and society at large, this phenomenon raises new issues in managing brand image: Should the company define segments with different brand perceptions and adapt its strategy to these perceptions, how can the city council satisfy the different stakeholders of a city brand, to what extent does the launch of a junior brand influence the perception of a senior brand with a similar name, to what extent do opinion leaders and antibrand activists influence the perception of a corporate brand. Second, there is a need for a process-oriented methodology, namely one that recognizes changes in brand images due to all the influences in the marketplace, to measure the brand perception and capture any change in the brand perception that is due to external factors, namely factors that are not decided by the company. Third, considering the link between brand image and brand equity, the method should focus on the contribution of attributes to brand equity, capturing the strengths, uniqueness and the favourability of these associations. And fourth, regarding the varied natures of brand attributes (functional, emotional, people, ethics, etc) depending on the type of brand (product brand, service brand, city brand and corporate brand), this technique to assess brand image perception should be applicable to all kinds of brands. As a result, the overall objective of this research is to provide profound insight into a measurement method of brand image perception and changes in brand image perception, capturing the strengths, uniqueness and favorability of brand attributes in different contexts, as a consequence of the new consumer focused and process-oriented views.
