Harmonic monsters

Journal of Approximation Theory, 2003
Using a theorem of \textit{S. J. Gardiner} [Harmonic approximation (1995; Zbl 0826.31002)], the author shows that there exists a harmonic function \(h\) on a non-empty open subset \(\Omega\) of \(\mathbb{R}^d\), where \(d\geq 2\), which behaves wildly near every boundary point of \(\Omega\).

Giving Concept of an Analog Notch Filter for Removing Interference from Engineering Systems to Engineering Students

Pakistan Journal of Engineering & Technology, 2019
Power lines exist everywhere. Interference of power frequency with signals of other systems (telephone, music, and so on) is inevitable. This results in deteriorating the quality signals of other systems to be used for accomplishing required tasks.

Harmonization: Consumer Protection

, 2014
This contribution gives an overview of law and economic works on consumer protection. It does so by taking three complementary angles: (1) assessing harmonization efforts regarding consumer protection in Europe, (2) presenting selected topics of substantive consumer law, and (3) analyzing the European consumer law enforcement from an economic point of ...
