We provide a new framework to identify demand elasticities in markets where managers rely on algorithmic recommendations for price setting and apply it data set containing bookings sample of midsized hotels Europe. Using nonbinding observed delay adjustments by decision makers, we demonstrate that control-function approach, combined with state-of-the-art model-selection techniques, can be used ...

In this paper, we propose a new algorithm for automated image registration or precise correction of satellite images. We assume that ground control points used previously are stored within the system. The algorithm first applies matching between the GCP chips stored and a new image to be registered and creates new control points. An automated stereo matching based on normalized cross correlatio...

purpose : to evaluate the efficacy of pattern visual evoked potentials (pvep), standard automated perimetry (sap), short-wavelength automated perimetry (swap), contrast sensitivity (cs), stereoacuity testing in detecting subclinical visual impairment in visually asymptomatic patients with multiple sclerosis (ms) and no history of optic neuritis methods : twenty-seven eyes of 27 patients (7 male...

In this paper, we describe a simple but effective and fast video activity detection algorithm to provide an efficient pre-processing tool for video camera feeds. It also presents a range of applications, including post production of TV camera video streams, analysis of surveillance videos, visual scene classification, and camera control for automated recordings etc. Given a video sequence, our ...

abstract in recent years, automatic weather stations have been widely used for recording meteorological data in different time scales. therefore the accurate estimation of eto by combination equations can be evaluated using these set of short time scales data. daily eto can also be calculated by summation of hourly eto values. the purpose of this study is to compare the eto values estimated by ...

OBJECTIVES Relative fundamental frequency (RFF) has shown promise as an acoustic measure of voice, but the subjective and time-consuming nature of its manual estimation has made clinical translation infeasible. Here, a faster, more objective algorithm for RFF estimation is evaluated in a large and diverse sample of individuals with and without voice disorders. METHODS Acoustic recordings were...

Estimating a person’s energy expenditure and activity intensity over time is an important component in managing various health conditions or tracking lifestyle choices. To implement an automatic estimation, most current systems ultimately require users to wear sensor devices. In contrast, this paper presents a framework for the contact-free, real-time estimation of energy expenditure, applicabl...
