Why Cumulative Decomposition Is Not as Bad as It Sounds

The global cumulative constraint was proposed for modelling cumulative resources in scheduling problems for finite domain (FD) propagation. Since that time a great deal of research has investigated new stronger and faster filtering techniques for cumulative, but still most of these techniques only pay off in limited cases or are not scalable. Recently, the “lazy clause generation” hybrid solvin...

Pattern from process : it is not as easy as it looks

In this paper, we present a model to investigate the possibility that the large-scale (of the order of 100 ms) spatial patterns of the adult bivalve Macomona liliana Iredale observed on an apparently homogeneous sandflat were the result of local biological dynamics rather than being driven by external factors. The model is age-structured, stochastic and spatially distributed on a 20 3 20 grid. ...

If It Sounds As Good As It Looks: Lessons Learned From Video Retrieval Evaluation

In many ways, music information retrieval (MIR) bears a closer resemblance to video information retrieval (VIR) than it does to text retrieval. Both music and video provide rich, complex sources of information having their own semantics. Both share the challenges of digitizing, segmenting and streaming, joined by problems relating to the representation of non-textual, non-verbal information. Be...

Measuring hearing aid outcomes--not as easy as it seems.

Outcomes measurement in audiology has received much attention because of the need to demonstrate efficacy of treatment, provide evidence for third-party payment, carry out cost-benefit analyses, and justify resource allocation. Outcomes measurement shows the benefits obtained from a hearing aid and determines the costs of obtaining those benefits. In this article, we discuss why the seemingly s...
