wide range of planar structures in new technologies has attracted special consideration. in this research vibration behavior of plates with non-linear edges is investigated by means of finite difference (fd) method. for this issue, classical and analytical solutions for plates with linear edges were analyzed and mutual equations, needed for numerical calculation were extracted. by expanding the...

Over the last twenty years we have seen an increasing use of in-work tax subsidies to encourage labor supply among low-income groups. In Sweden, a non-targeted earned income tax credit was introduced in 2007, and was reinforced in 2008, 2009 and 2010. The stated motive of the reform was to boost employment; in particular to provide incentives for individuals to go from unemployment to, at least...

A number of Privacy Enhancing Technologies (PETs) have been proposed in the last three decades offering unconditional communication anonymity to their users. Unconditional anonymity can, however, be a security threat because it allows users to employ a PET in order to act maliciously while hiding their identity. In the last few years, several technologies which revoke the identity of users who ...

E-commerce technologies have reached a level of maturity where many businesses are no longer hampered by technological limitations. However, the adoption of ecommerce technologies is slower than anticipated. We argue one of the limitations is a psychological barrier, which is created by the perception that e-commerce technologies are a whole new set of technologies which are completely differen...

Domestic Objects are emerging as a source for embedding ubiquitous computer technologies. The current focus on single objects or a singular function neglects people’s diverse functional use of domestic objects and their cultural significances at home. Based on ethnographic interviews, this paper reports how people utilize domestic objects in relation to activities and domestic spaces. The paper...
