Previously undiagnosed Reinke edema as a cause of immediate postextubation inspiratory stridor
2015
Reinke edema (RE) is an uncommon lesion of the vocal folds and a potential cause of complications during airway management. We report the case of a woman with previously unknown RE admitted to the intensive care unit who experienced postextubation inspiratory stridor immediately after separation from mechanical ventilation. RE should be considered among causes of postextubation stridor.
Precision of a commercial hartmann-shack aberrometer: limits of total wavefront laser vision correction.
2012
Purpose To assess the intrasession and intersession precision of higher-order aberrations (HOAs) measured using a commercial Hartmann-Shack wavefront sensor (Zywave; Bausch & Lomb) in refractive surgery candidates. Design Prospective, experimental study of a device. Methods To analyze intrasession repeatability, 1 experienced examiner measured 30 healthy eyes 5 times successively. To study intersession reproducibility, the same clinician obtained measurements from another 30 eyes in 2 consecutive sessions at the same time of day 1 week apart. Results For intrasession repeatability, excellent intraclass correlation coefficients (ICCs) were obtained for total ocular aberrations, total HOAs, a…
Accommodative Stimulus-Response Curve with Emoji Symbols
2017
Purpose. To evaluate the static measurement of the accommodative stimulus-response curve with emoji symbols. Methods. The accommodative stimulus-response curve was measured in 18 subjects using a Hartmann-Shack sensor to obtain the objective accommodative response from the Zernike defocus term. Measurements were acquired at different accommodative demands, from 0 to 3 D with a step of 0.5 D. Detailed and nondetailed emoji targets were used with two different sizes, corresponding to the two most common visual angles used in smartphones. Results. A regression analysis was performed to fit the mean results obtained for each target. The determination coefficient was R2≥0.988 for all targets. Fo…
Uzņēmuma tēla ietekme uz zīmola popularitāti, pamatojoties uz "Nike Inc." kompānijas piemēru.
2015
Šī diplomdarba tēmas aktualitāti nosaka tas, ka pētījumi un praktiskā pieredze parāda, ka mūsdienās veiksmīgai kompānijai ir jābūt zīmola stratēģijai, kas ir virzīta uz patērētāja uzticības veidošanu. Tā kā zīmola „vērtību” nosaka patērētāja gatavība iegādāties preci par daudz augstāku cenu, ja tirgū ir citu prečzīmju analoģiskās preces. Šī diplomdarba mērķis ir uzņēmuma tēla ietekmes uz zīmola popularitāti būtības atklāšana, izanalizējot teoriju. Kā arī izpētīt kompānijas "Nike Inc." zīmola un tēla izveidi un tā lomu uzņēmuma darbībā. Izpētīt kompānijas "Nike Inc." tēlu patērētāju apziņā. Diplomdarbs sastāv no teorētiskās literatūras apkopojuma par zīmola un tēla teorētiskiem aspektiem, no…
Repeatability of in-vitro optical quality measurements of intraocular lenses with a deflectometry technique effect of the toricity
2018
Aim To evaluate the repeatability of an optical device for measuring the Zernike coefficients of toric intraocular lenses (IOLs) and assess whether its toricity has any impact in its repeatability. Methods An experienced technician used the NIMO TR1504 to measure the Zernike coefficients 30 times for an aperture of 4.50 mm for all lenses included. The IOLs included were divided into two group: toric and non-toric ones. The cylindrical powers of the toric lenses included in the present study were 1.00, 1.50, 2.25, 3.00 and 3.75 D. Finally, the repeatability of the NIMO TR1504 was described in terms of within subject standard deviation (Sw) and repeatability limit. Results The Sw was smaller …
Influence of dispersion on the resonant interaction between three incoherent waves
2005
We study the influence of group-velocity dispersion (or diffraction) on the coherence properties of the parametric three-wave interaction driven from an incoherent pump wave. We show that, under certain conditions, the incoherent pump may efficiently amplify a signal wave with a high degree of coherence, in contrast with the usual kinetic description of the incoherent three-wave interaction. The group-velocity dispersion is shown to be responsible for a spectral filtering process, in which the coherence of the generated signal increases, as the coherence of the pump wave decreases. As a result, the coherence acquired by the signal in the presence of an incoherent pump, is higher than that a…
New Objective Refraction Metric Based on Sphere Fitting to the Wavefront
2017
Purpose. To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil sizes.Methods. A sphere is fitted to the ocular wavefront at the center and at a variable distance,t. The optimal fitting distance,topt, is obtained empirically from a dataset of 308 eyes as a function of objective refraction pupil radius,r0, and used to define the formula of a new wavefront refraction metric (MTR). The metric is tested in another, independent dataset of 200 eyes.Results. For pupil radiir0≤2 mm, the new metric predicts the equ…
Jesus fra Nikea? - Tre merknader til Oskar Skarsaunes visdomskristologi
2014
Author's version of an article in the journal: Teologisk tidsskrift. Also available from the publisher at: http://www.idunn.no/ts/tt/2014/03/jesus_fra_nikea_-_tre_merknader_til_oskar_skarsaunes_visdo This article discusses three key aspects of the wisdom Christology of Oskar Skarsaune, as it is portrayed in his influential book Inkarnasjonen – myte eller faktum? (1988; Incarnation – myth or fact?, 1991): (1) The claim that Jesus through his “first-person speech” speaks with divine authority that makes an identification with the wisdom figure inevitable. (2) The emphasis that the messiah category is insufficient to describe the person of Jesus. (3) The emphasis that wisdom is begotten – and …
Analiziranje pozicioniranja glazbenih usluga putem kvalitativnog istraživanja

Information technologies have produced new ways of distributing and consuming music, mainly by youth, in relation to both goods and services. In the case of goods, there has been a dramatic shift from traditional ways of buying and listening to music to new digital platforms. There has also been an evolution in relation to music services. In this sense, live music concerts have been losing their audiences over the past few years, as have music radio stations, in favor of streaming platforms. Curious about this phenomenon, we conducted an exploratory research in order to analyze how all these services, both traditional and new ones were perceived. Specifically, we aimed to study youth´s asse…
Hardware Computation of Moment Functions in a Silicon Retina Using Binary Patterns
2006
International audience; We present in this paper a method for implementing moment functions in a CMOS retina for shape recognition applications. The method is based on the use of binary patterns and it allows the computation of different moment functions such geometric and Zernike moments of any orders by an adequate choice of the binary patterns. The advantages of the method over other methods described in the literature is that it is particularly suitable for the design of a programmable retina circuit where moment functions of different orders are obtained by simply loading the correct binary patterns into the memory devices implemented on the circuit. The moment values computed by the m…
