Adaptive Decoupling of Multivariable Systems

For many industrial processes, it is of interest to design a decoupling precompensator. The precompensator makes it possible to design controllers based on single-input-single-output models of the process. A model of the process must be known to design the precompensator. This paper shows how the precompensator can be designed adaptively using input-output measurements. The precompensator is first

When the learned system is activated

This paper focuses on the discussion of the general characteristics of 12 Swedish learners’ oral production of the Chinese aspect markers le, guò, zài, and zhe. Their oral performance is discussed with respect to Krashen’s Monitor hypothesis (1978, 1981, 1987) on the role of conscious learning. The functions of the Monitor in planning, editing and correcting is discussed respectively in relation t

Robust synchronisation of unstable linear time-invariant systems

A framework based on the gap metric and integral quadratic constraints (IQCs) is developed for analysing robust synchronisation of heterogenous linear time-invariant networks. Both the agents and the communication channels are allowed to be dynamic and unstable. Structural properties of the uncertainty are described by IQCs and exploited in synchronisation analysis as a means to reduce conservatis

Follow Your Heart and Nothing Else: Thoughts on the Religious Anarcho-Primitivist Message of Lynyrd Skynyrd

This article maintains that the well-known Souther Rock band Lynyrd Skynyrd has a long-neglected religious anarcho- primitivist message in their lyrics. By neglecting the state, celebrating simple living, and advocating the individual conscience as the highest moral authority, the band's theological-political stance seems to approximate the anarcho-primitivst teachings of the Dao de Jing.

A novel gene family encoding proteins with highly differing structure because of a rapidly evolving exon

Despite vast differences in primary structure, it is here shown that several predominant semen proteins are encoded by genes that belongs to a common family. Members have their transcription unit split into three exons: the first encoding the signal peptide, the second the secreted protein, while the third exon solely consists of 3' non-translated nucleotides. The first and the third exon are cons
