In this paper, three systems for classification of stress in speech are proposed. The first system makes use of linear short time Log Frequency Power Coefficients (LFPC), the second employs Teager Energy Operator (TEO) based Nonlinear Frequency Domain LFPC features (NFD-LFPC) and the third uses TEO based Nonlinear Time Domain LFPC features (NTD-LFPC). The systems were tested using SUSAS (Speech...

Fibrous tows used in continuous fibre-reinforced polymers (CFRPs) deform geometrically during the production of composite products. The cross-sectional geometry of the tow is influenced by the load-induced deformation mechanisms. A study of the effect of two commonly assumed geometrical tow shapes on an equivalent pressure distribution in a tow-on-a-pin spreading arrangement was performed. The ...

This experiment compares the performance of two contest designs: a standard winnertake-all tournament with a single fixed prize, and a novel proportional-payment design in which that same prize is divided among contestants by their share of total achievement. We find that proportional prizes elicit more entry and more total achievement than the winner-take-all tournament. The proportional-prize...

(1) Let R be a division ring. Prove that every module over R is free. You will need to use Zorn’s lemma: Recall that a partially order set (=poset) S is a set with a relation x ≤ y defined between some pairs of elements x, y ∈ S, such that: (i) x ≤ x ; (ii) x ≤ y and y ≤ x implies x = y ; (iii) x ≤ y , y ≤ z ⇒ x ≤ z . A chain in S is a subset T ⊂ S such that for all t, t ′ in T , either t ≤ t ′...

It is important for MIS educators to have a good understanding of what IT knowledge and skills are required in business. In this study, 103 open job positions in the Midwestern United States were investigated via semi-structured interviews with hiring companies. The interviews with key business recruiters suggest that IT knowledge and skills are significantly considered during the recruiting pr...

The article contains the algorithm for searching a certain kind of bridges in the protection graph of Take-Grant model. The proposed algorithm is based on a classical breadth-first search algorithm.

Industries such as Banking and Finance, Healthcare, Hospitality and Technology are currently experiencing high attrition rates. You, as a HR manger or senior management executive, may know some apparent causes for attrition in your company. And you also know the high costs of attrition and the negative impact it has on customer facing scenarios. But how often have you felt that if you had known...
