An iterative method is presented for computed tomography imaging spectrometer (CTIS) image reconstruction in the presence of both photon noise in the image and postdetection Gaussian system noise. The new algorithm, which assumes the transfer matrix of the system has a particular structure, is evaluated experimentally with the result that it is significantly better, for larger problems, than bo...

The aim of this study is to evaluate and compare the human-biometeorological conditions at two resorts in Ukraine: a coastal resort located Odesa southern Ukraine an inland situated by lake Svityaz northwest Ukraine. results can facilitate assessment tourist potentials both locations tourism industry, tour operators, tourists. evaluation based on analysis Physiologically Equivalent Temperature ...

The computed tomography imaging spectrometer (CTIS) is a hyperspectral (HSI) approach where spectral and spatial information of scene mixed during the process onto monochromatic sensor. This mixing due to diffractive optical element integrated into underlying optics creates set diffraction orders. To reconstruct three-dimensional cube from CTIS sensor image, iterative algorithms were applied. U...

The current study examines whether an online cyber identity course, which was based on the community of inquiry model, significantly affected self-efficacy perception school counselor candidates (SCC) in terms technology integration. Forty-four SCC, selected using criterion sampling method, participated a mixed-method design by taking one-week course. version Computer Technology Integration Sur...

Climate and tourism are strong correlated. Urban areas have a relevance concerning not only to cultural tourism but also for recreation. The high discussed topic of global change is focused in the tourism climatology as well. We analyzed exemplarily the climate potential and its variation of Freiburg. The analysis is based on the simulations of the regional climate models REMO and CLM for the A...

Abstract The Extreme-ultraviolet Snapshot Imaging Spectrograph (ESIS) launched on a sounding rocket from White Sands Missile Range 2019 September 30. ESIS is computed tomography imaging spectrograph (CTIS) designed to map emission line profiles across wide field of view, revealing the structure and dynamics small-scale transient events that are prevalent at transition region temperatures. In th...

Optimal deployment of limited emergency resources in a large-scale area is of interests to public agencies at all levels. In this paper, the problem of allocating limited emergency service vehicles including fire engines, fire trucks and ambulances among a set of candidate stations is formulated as a mixed integer linear programming model, in which the objective is to maximize the service cover...

Standardized management of data elements (DEs) for Case Report Form (CRF) is crucial in Clinical Trials Information System (CTIS). Traditional CTISs utilize organization-specific definitions and storage methods for Des and CRFs. We developed metadata-based DE management system for clinical trials, Clinical and Histopathological Metadata Registry (CHMR), using international standard for metadata...

The incentive for the 4D-IS concept was driven by the need to adequately resolve all four dimensions of data (2D spatial, spectral, and temporal) with a single, radiometrically calibrated sensor. Very fast changing phenomena are of interest; including missile exhaust plumes, missile intercept events, and lightning strikes, hypervelocity impacts, etc. Present sensor capabilities are limited to i...
