Using black hole perturbation theory, we calculate the gravitational waves produced by test particles moving on bound geodesic orbits about rotating black holes. The orbits we consider are generic — simultaneously eccentric and inclined. The waves can be described as having radial, polar, and azimuthal “voices”, each of which can be made to dominate by varying eccentricity and inclination. Alth...

background & aim: families of patients with schizophrenia face with stigma as the most challenging psychosocial pressure; due to its negative consequences on mental health of family and important role of family in a treatment of these patients, it is considered as important mental health issues. comparing the effect of in our own voice-family with psychoeducation on stigma in the families of pa...

[Abstract] This article examines, through the grooves of the record disc as a site, the inscription of the human voice onto the recorded medium, and the way recording technology has changed how the listener hears and comprehends the physical body. Recording technology allowed human presence to be captured onto a concrete and tactile medium, and enabled the material object of the recording to th...

This paper presents a Bayesian nonnegative matrix factorization (NMF) approach to extract singing voice from background music accompaniment. Using this approach, the likelihood function based on NMF is represented by a Poisson distribution and the NMF parameters, consisting of basis and weight matrices, are characterized by the exponential priors. A variational Bayesian expectationmaximization ...

This study builds on the multi-stakeholder perspective to explore nature of stakeholder engagement across key areas value creation in museum context. The empirical research followed a multiple case design, based three cases selected accordance with maximum variation strategy. investigation involved qualitative content analysis primary and secondary sources. findings reveal context-bound percept...

rupture and wrinkling are two prevalent phenomena that happen in hydro-forming process. many efforts have been made to achieve the upper and lower bounds for the pressure related to rupture and wrinkling of sheet, respectively. the aim of this investigation is to improve the upper bound of fluid pressure in hydro-forming process by hemispherical punch. in this article, analytical study of the u...

the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...
