A speaker’s intentions can be represented by domain actions (domainindependent speech act and domain-dependent concept sequence pairs). Therefore, it is essential that domain actions be determined when implementing dialogue systems because a dialogue system should determine users’ intentions from their utterances and should create counterpart intentions to the users’ intentions. In this paper, ...

Local methods based on spatio-temporal interest points (STIPs) have shown their effectiveness for human action recognition. The bag-of-words (BoW) model has been widely used and dominated in this field. Recently, a large number of techniques based on local features including improved variants of the BoW model, sparse coding (SC), Fisher kernels (FK), vector of locally aggregated descriptors (VL...

We study the role of small-size instantons in the determination of the topologi-cal susceptibility of the 2-d O(3) σ model on the lattice. In particular, we analyze how they affect the non-perturbative determination, by Monte Carlo techniques, of the renormalizations on the lattice. As a result, we obtain a high-precision non-perturbative determination of the mixing with the unity operator, fin...

Tectona grandis L. (Teak) is one of the commercial plants which often used in Southeast Asia. Globally, total area planted teaks reaches 3 million hectares, with about 31% land located Indonesia. Preliminary phytochemistry showed bioactive constituents as alkaloids, tannins, flavonoids and phenolic compounds. Isolation characterization by several methods were reported for quantifying secondary ...
