Film induced tourism or film is a result of destination image formation and development through industry with collaboration other stakeholders (policy makers, private public investors, scholars etc.). This postmodern phenomenon links driven emotions to the filming locations at same time responsible for positive negative formation. In Lithuanian academic discourses this theory, as well impact fi...

Dry plate glass negatives are important part of the cultural, historical and visual heritage in history of Iran. Structural changes due to factors affected them over time, can cause deterioration in the image. Identifying deteriorations in dry plate glass negatives can help to provide better solutions in preserving them. The investigation of sample by Fourier transform infrared spectroscopy ...

The Mehdiabad zinc-lead deposit, which is located at the East of Mehriz city, is a carbonate-hosted ore deposit lying in the dolomitic rocks of Taft Formation. This deposit is composed of oxide-carbonate and sulfide ores. Different spectral processing techniques were applied to ASTER and Landsat 8-OLI multispectral images to detect different mineralization zones and associated alterations. In O...

In synthetic aperture radar (SAR), many adverse conditions may cause errors in the raw phase-history data. Autofocus methods are commonly used in SAR to mitigate the effects of these problems. Over the years, many types of autofocus have algorithms have been created, however, each has implicit assumptions restricting their use. The backprojection image formation algorithm places few restriction...

The outstanding characteristic of the Shroud image is the discontinuous distribution of the color on the surface. Color appears predominantly on the highest parts of the threads in the weave, as can be seen from the excellent photomicrographs taken by Mark Evans of STURP. Copies of Evans' collection are available from the Shroud web site (www.shroud.com). I would especially recommend ME-029, a ...

The anisotropy induction by light in self-induced molecular aggregations ensemble of azodyes has been studied. In the dynamic regime of anisotropy photoinduction the video-microscopy investigations of the film having photoinduced anisotropy in the crossed polarizers have been conducted. It is shown that image formation herein can be carried out in the way of light modulation of the granular ani...

one of the main concerns of processing algorithms used in synthetic aperture radar (sar) with a ballistic motion is the compensation of all phase errors in the data received from the target to achieve a clear picture of the target. in this article, by using range doppler algorithm and phase-gradient auto focus algorithm, imagery in one sar with a ballistic motion is considered according to the ...

This paper proposes a system to estimate the 3D position and velocity of vehicles, from images acquired with a monocular camera. Given image regions where vehicles are detected, Gaussian distributions are estimated detailing the most probable 3D road regions where vehicles lay. This is done by combining an assumed image formation model with the Unscented Transform mechanism. These distributions...

In this work we introduce a rigorous computational method for finding heteroclinic solutions of a system of two second order differential equations. These solutions correspond to standing waves between rolls and hexagonal patterns of a two-dimensional pattern formation PDE model. After reformulating the problem as a projected boundary value problem (BVP) with boundaries in the stable/unstable m...
