A new method is proposed for locating saddle points on potential energy surfaces. The method involves walking on the ridge separating reactants’ and products’ valleys toward its minimum, which is a saddle point in coordinate space. Of particular advantage for ab inirio calculations, the ridge method does not require evaluation of second derivatives of the potential energy. Another important fea...

The cumulative reaction probability (CRP) (the Boltzmann average of which is the thermal rate constant) has been calculated for the reaction H,+OH++HzO+H in its full (six) dimensionality for total angular momentum J=O. The calculation, which should be the (numerically) exact result for the assumed potential energy surface, was carried out by a direct procedure that avoids having to solve the co...

A Product Line Potential Analysis enables us to make a quick decision as to whether the product line approach (PLA) is suitable for a given set of products and target market. The PLA framework offers no support for this as yet. A Product Line Potential Analysis is executed in a half-day workshop. A structured interview based on a questionnaire examines products, software, markets, and customers...

In this paper, we present an automated video analysis system which addresses segmentation and detection of human actions in an indoor environment, such as a gym. The system aims at segmenting different movements from the input video and recognizing the action types simultaneously. Two action segmentation techniques, namely color intensity based and motion based, are proposed. Both methods can e...

Vibration-rotation and pure rotational data in the X2Σ+ ground state and electronic data from the A2Π – X2Σ+ and B2Σ+ − X2Σ+ transitions of CaH and CaD were used in the quantum-mechanical direct-potential-fit (DPF) analysis to determine an analytic potential energy function for the X2Σ+ ground state of CaH, and a radial correction function for the CaD isotopologue. The potential energy function...
