In this paper we present two applications of a Stability Theorem of Hilbert frames to nonharmonic Fourier series and wavelet Riesz basis. The first result is an enhancement of the Paley-Wiener type constant for nonharmonic series given by Duffin and Schaefer in [6] and used recently in some applications (see [3]). In the case of an orthonormal basis our estimate reduces to Kadec’ optimal 1/4 re...

In this work, theoretically/mathematically simulated (TMS) model is presented for the photoacoustic (PA) frequency response of a semiconductor in minimum volume PA cell. By analyzing TMS model, influences thermal diffusivity and linear coefficient expansion on silicon sample were investigated two methods developed their estimation. The first one self consistent inverse procedure solving exponen...

In the theory of wavelet frames, known Daubechies bases have been generalized to compactly supported (Daubechies-like) while bandlimited Meyer not date. this study, we will generalize basis into non-separable Meyer-like frames. By using a characteristic function mask Fourier transform one-dimensional scaling with width parameter, can produce family frame functions and associated After that, by ...

Using periodic density-functional theory (DFT), we investigated the structure and cohesive properties of the -alumina 11 tilt grain boundary, with and without segregated elements, as a model for the thermally grown oxide in jet engine thermal barrier coatings. We identified a new low-energy structure different from what was proposed previously based on electron microscopy and classical potentia...

According to Milner and Goodale's theory of the two visual streams, the dorsal (action) stream controls actions in real-time, whereas the ventral (perceptual) stream stores longer-term information for object identification. By this account, the dorsal stream subserves actions carried out immediately. However, when a delay is required before the response, the ventral (perceptual) stream is recru...

Transcranial magnetic stimulation (TMS) has been widely used in studies of human motor and cognitive functions as well as in clinical treatment. Biophysical mechanism underlying its e!ect is, however, largely unknown. Here, we develop a theory to calculate the e!ect of magnetic stimulation on arbitrary neuronal structure. Then, we employ a computer simulation which combines a realistic multicom...

One of the key challenges that organizations face when trying to integrate knowledge across different functions is the need to overcome knowledge boundaries between team members. In cross-functional teams these boundaries, associated with different knowledge backgrounds of people from various disciplines, create communication problems, necessitating team members to engage in complex cognitive p...

transcranial magnetic stimulation (tms) has been applied to a growing number of psychiatric disorders as a neurophysiological probe, a primary brain-mapping tool and a candidate treatment. although most investigations have focused on the treatment of major depression, increasing attention has been paid to anxiety disorders. the aim of this study is to long time (for 30 days) effect of repetitiv...

We demonstrate the technological value of non-monotonic logics by an example: We use prioritized defaults for candidate generation in diagnosis from first principles. We implement this non-monotonic logic by TMS similar to default logic. Prioritized defaults allow an easy formu­ lation of a diagnosis problem including state­ ments such as 'eletrical parts are more reliable than mechanical ones'...
