In light of the recent data from BES collaboration for χc0 → V V , PP and SS, and from CLEO-c for ηη, η′η′ and ηη′, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as χc0,2 → V V , PP and SS in a recently proposed parametrization scheme. An overall agreement with the data is achieved in χc0,2 → V V and PP , while in χc0 → SS we find that a possible ex...

Barabanov norms have been introduced in Barabanov (Autom. Remote Control, 49 (1988), pp. 152–157) and constitute an important instrument in analyzing the joint spectral radius of a family of matrices and related issues. However, although they have been studied extensively, even in very simple cases it is very difficult to construct them explicitly (see, e.g., Kozyakin (Discrete Contin. Dyn. Sys...

We examine various strategies for exact approaches to the 2dimensional strip packing problem (2SP) with and without rotations of 90 degrees. We first develop a branch-and-bound algorithm based on the sequence pair representation. Next, we focus on the perfect packing problem (PP), which is a special case of 2SP where all given rectangles are required to be packed without wasted space, and desig...

This paper analyses the influence of marketing and organisational changes on the innovation process. Using data from the German Community Innovation Survey (CIS) 2007, two questions are investigated. Firstly, do certain firm and market characteristics trigger certain innovation strategies? This allows the examination of whether product/ process (PP) and marketing/ organisational (MO) innovation...
