离散描述系统干扰解耦状态观测器设计及鲁棒故障诊断

对一类带有未知输入干扰的离散描述系统,提出了一种新型的干扰解耦状态观测器;对一类带有未知输入干扰和有界不确定性的离散描述系统,以状态观测器为基础,利用故障信号与观测误差之间的关系,构造了一种带有未知输入干扰的离散描述系统的鲁棒故障诊断方法.该方法不但能够检测系统中是否出现故障,而且还可以估计出故障的幅值大小.文中还讨论了阈值的选取、该算法能检测到的最小故障信号和故障信号的估计误差,其仿真结果表明了该方法的有效性.

Sex,sport and money: voice,choice and distributive justice in England,Scotland and Wales

The three British Sports Councils are instrumental in developing the policy landscape for sport and physical education (PE). They aspire to equality between the sexes in ‘sport and physical recreation’ (SPR), in keeping with their Royal Charters [Sport England. (1996/2009). Royal Charter of English Sports Council (Sport England). Retrieved from https://www.sportengland.org/media/10309/consolidated-royal-charter.pdf; Sport Scotland. (1996). The Royal Charter for the Scottish Sports Council. Retrieved from http://www.sportscotland.org.uk/sportscotland/Documents/Resources/sportscotlandRoyalCharter.pdf; Sport Wales. (1997). The Royal Charter of the Sports Council for Wales. Retrieved from http://sport.wales/media/128780/royal%20charter.doc] and the Equality Act [HM Government. (2010). Equality Act 2010. London: TSO. Retrieved from http://www.legislation.gov.uk/ukpga/2010/15/pdfs/ukpga_20100015_en.pdf]. As public bodies they are committed to eliminating direct and indirect discrimination in provision, and advancing equality. One of their main functions is the distribution of public money, and all collect participation data detailing the different SPR choices of the sexes. These are primary planning tools in the three home countries. This paper investigates whether equality in relation to sex is considered a ‘first-order’ question of distributive justice for the Councils. Therefore, the funding awarded to the top SPR preferences by sex for each Country is presented. Defining SPR determines eligibility for funding and the boundaries of the SPR infrastructure which influences and interfaces with sport, school sport and PE. Consequently, critical feminist political and economic theory is used to evaluate the Councils’ framing of SPR and equality in relation to sex. Male preferences are disproportionately grant-aided leaving those of females significantly under-funded. Although the remit of the Councils is ‘sport and physical recreation’ this is usually reframed by them as ‘sport’. Equality is generally considered a second-order question of justice, and outsourced to national governing bodies of sport. Further dance, one of the most popular female SPR activities for girls, has not, until 2016, been designated as SPR in England and has been ineligible for funding. These policies suggest indirect discrimination against women and girls who disproportionately prefer physical recreation and dance to competitive sport. Therefore, the Sports Councils and/or overarching government departments may not be fulfilling their legal requirements under the Equality Act.

Destined to Design? How and Why Australian Women Choose to Study Industrial Design

Despite over three decades of legislation and initiatives designed to tackle the traditional gender divide in the science, technology and design fields, only a quarter of the registered architects in Australia are women. There are no statistics available for other design disciplines, with little known about why women choose design as a career path and who or what influences this decision. This qualitative research addresses this knowledge gap, through semi‐structured in‐depth interviews conducted with 19 Australian women who completed an industrial (product) design degree. Thematic analysis revealed three key themes: childhood aptitude and exposure; significant experiences and people; and design as a serendipitous choice. The findings emphasise the importance of early exposure to design as a potential career choice, highlighting the critical role played by parents, teachers, professionals and social networks.
