Open problems for equienergetic graphs

The energy of a graph is equal to the sum of the absolute values of its eigenvalues. Two graphs of the same order are said to be equienergetic if their energies are equal. We point out the following two open problems for equienergetic graphs. (1) Although it is known that there are numerous pairs of equienergetic, non-cospectral trees, it is not known how to systematically construct any such pa...

Dendro: Collaborative Research Data Management Built on Linked Open Data

Research datasets in the so-called “long-tail of science” are easily lost after their primary use. Support for preservation, if available, is hard to fit in the research agenda. Our previous work has provided evidence that dataset creators are motivated to spend time on data description, especially if this also facilitates data exchange within a group or a project. This activity should take pla...

Kete and Koha: integration built on open standards

Purpose This study explores the benefits of using Open Standards to support the gathering of relevant data from a variety of sources from across an organizationʼs software applications and also from completely external information providers. Design/methodology/approach Looks at the history of Koha and Kete projects and their interactions. Features particular concentration on Keteʼs development....

Open Problems on Partial Words

The theory of formal languages is widely accepted as the backbone of theoretical computer science. It mainly originated from mathematics (combi-natorics, algebra, mathematical logic) and generative linguistics. Later, new specializations emerged from areas of either computer science (concurrent and distributed systems, computer graphics, artificial life), biology (plant development , molecular ...
