Distortion Estimates for Adaptive Lifting Transforms with Noise – Support Document Fabio Verdicchio and Yiannis Andreopoulos APPENDIX A A.1. Validation of Observation 1 Assuming the experimental settings described in Section V.A, we consider the approximation of (14), i.e. the relative impact of the term ∆ ∆ M v in the synthesis error ∆x . The approximation of (14) involves only one lifting ste...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

in the present study, air quality analyses for ozone (o3) were conducted in shiraz, a city in the south of iran. the measurements were taken from 2011 through 2012 in two different locations to prepare average data in the city. the average concentrations were calculated for every 24 hours, each month and each season. results showed that the highest concentration of ozone occurs generally in the...

Brief smooth eye-velocity responses to target position steps have been reported during smooth pursuit. We investigated position-error responses in eight healthy human subjects, comparing the effects of a step-ramp change in target position when imposed on steady-state smooth pursuit, vestibuloocular reflex (VOR) slow phases, or fixation. During steady-state pursuit or VOR, the target performed ...

The authors analyse a novel macrodiversity scheme, the multiplydetected macrodiversity (MDM) scheme, whch relies on postdetection combining, as opposed to the traditional macrodiversity techniques, which are selection-based. The average fraction of the cell area is evaluated with an improved bit error rate (BER) performance, average BER improvement, and improvement in the average outage probabi...

in this paper, two methods have been used: multi-layer perceptron artificial neural network (ann-mlp) and universal kriging to estimate of velocity field. neural network is an information processing system which is formed by a large number of simple processing elements, known as artificial nerves. it is formed by a number of nodes and weights connecting the nodes. the input data are multiplied ...
