基于HHT及主成分分析的光缆识别信号特征提取

为了解决当环境噪声较严重时光强难以维持稳定,容易误判目标光缆问题,根据干涉信号非线性、非平稳的时域特征,提出了一种希尔伯特-黄变换及主成分分析相结合的信号处理方法。探测器接收的干涉信号对进行经验模态分解,把分解得到的本征模态分量作为列向量构建主成分分析的样本矩阵,以奇异值的贡献率进行有效成分筛选;然后采用主成分分析算法完成降噪优化。最后将降噪后的信号进行希尔伯特-黄变换得到瞬时特征信号,完成目标光缆识别。结果表明,相同噪声环境下所提方法可有效提高回波干涉信号的信噪比。因此,研究结果可以降低误判目标光缆的概率,帮助工程人员更有效地完成光缆识别。

Perceptions of older consumers regarding food packaging as a prerequisite for its improvement: A case study of Polish market

In many societies, the scale of demographic change associated with increased longevity has the potential to influence the market for consumer goods. As a result, continuous improvement in packaging design that takes into account the needs of older people should become an important challenge for both packaging producers and product manufacturers. Due to the fact that there is limited research concerning the design of food packaging for older people, the aim of the study was to identify the expectations of this group of consumers in this respect. Milk packaging was selected as a model subject of study. Factors influencing older consumers and their buying patterns when purchasing milk have been thoroughly examined. The research was conducted among people over the age of 60 with the use of three methods: a questionnaire (600 subjects), an in‐depth interview (60 subjects) and eye tracking (30 subjects). The results of the study show that older consumers have specific preferences regarding packaging type and design. When considering milk packaging, for example, they prefer glass bottles, simple graphics and font and subdued colours. They most frequently look for information concerning the product's expiration date, its producer's name and its composition. Eye tracking revealed that the older the consumers are, the more problems with finding expiration date they have. The time required to find such information, however, strongly depends on where exactly the expiration date is printed on the packaging. The preferred place in this case is the top of the bottle. Older consumers identify product's brand with the name of the producer. Moreover, the absence of the term ‘ingredients’: on the milk packaging oftentimes causes confusion among older people, who are concerned about potential food additive content.     

Advertising targeting young children: an overview of 10 years of research (2006–2016)

A review of 138 published academic articles was conducted to provide an up-to-date and comprehensive overview of academic research of the past decade (2006–2016) on advertising directed to young children up to 12 years old. The research overview resulted in a conceptual framework comprising five research domains that were found to be most prominent. For each of these five domains, an overview, discussion and future research agenda is presented. We conclude that much of the research of the past decade included food advertising and its effects. Progress has been made in the domain of children's advertising processing, specifically with regard to advertising literacy. Despite the growing importance of embedded advertising, many of the new ad formats remain neglected (e.g. native and mobile advertising). Additionally, only a few studies investigated which executional factors (e.g. humour) are effective in advertisements to target children and social influences are also less often considered.
