The concepts of social value creation and sustainability are acquiring a growing relevance in the vision shared by tourism industry’s major stakeholders. Our aim was to determine hybrid impact-value model capable measuring product through use indicators impact stakeholder actions during process creating generating products. An initial static is complemented second dynamic vision, based on measu...

background: poor sleep quality (sq) is common among patients after coronary artery bypass graft surgery (cabg). this study attempted to determine the status of sq following an intervention based on the precede-proceed model in patients with poor sq after cabg. methods: this study was a randomized clinical trial. the study sample, including 100 patients referred to the cardiac rehabilitation cli...

a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...

This study presents a novel hybrid model based on a two-dimensional (2-D) site-specific model and a statistical model to investigate space diversity in indoor environments. The statistical model describes the field scattered by rough surface boundaries and randomly positioned scatterers, which may be important when one or both of the receiving and transmitting antennas are close to the boundari...

More and more firms shift their focus from offering standalone products or services towards hybrid value creation. While previous research clearly states four value creating attributes, their role and impact in different types of hybrid offerings is so far unclear. To close this gap, this paper investigates 52 successful offerings of hybrid value creation and provides an organizational perspect...
