TL;DR: In this article, a system enables output, used for calibration of a document processing system (DPS), to be effective without the need for remeasurement, where the DPS output is generated, together with the calibration target.
Abstract: PROBLEM TO BE SOLVED: To re-sequence data without the need for remeasurement. SOLUTION: A system enables output, used for calibration of a document processing system(DPS), to be effective. Calibration target is termed for evaluating the range of output by the DPS. This target includes a plurality of target elements and element orientation information representing a physical layout of the target elements in the DPS output. The DPS output is generated, together with the calibration target. Characteristic values of the DPS output are measured in correspondence with individual target elements. When it is recognized that wrong sequencing has been performed for measurement of the target elements, the measurement values of the target elements of the DPS are re-sequenced, based on, a desired sequence for calculating an appropriate calibration function without the need for remeasurement.

TL;DR: Lease leasing is a financing device in the form of a lease as mentioned in this paper, which has been used as an effective alternative to the purchase of equipment, and has become one of the key engines of innovation and economic growth in Germany.
Abstract: Finance leasing is a financing device in the form of a lease. It has been used as an effective alternative to the purchase of equipment. Usually a finance leasing transaction works in the following way. At the request of the lessee, with his specification of the asset and selection of the supplier,1 the lessor enters into a supply agreement with the supplier. The lessor acquires the asset from the supplier, who receives outright payment from the lessor. Then, the lessor leases the asset to the lessee for a term which is usually most of the useful life of the asset, in return for the lessee’s payment of rental. This rental is calculated to cover the capital outlay of the lessor and also to give him a margin of profit. During the lease period, the lessee enjoys the possession of the asset and the profits resulting from the use of it. He also undertakes to maintain it in good order and is responsible for loss or damage to it. At the end of the lease period, either the lessee would continue to hire the same asset for a secondary period and pays a peppercorn rental toward it, or the asset would be sold, often by the lessee on behalf of the lessor, and the lessee would share a substantial proportion of the proceeds of the sale.Leasing is nowadays an established part of commercial life. The realization that wealth is created through the use of an asset rather than through the fact of its ownership has long been recognized. German company managers have an instinctive reverence for the principle of 'mine and thine', so it is hardly surprising that in the early 1960s they were somewhat skeptical about this newfangled alternative to the traditional forms of credit. Since then, however, leasing has become an investment instrument of unrivalled popularity, and today it accounts for just under half of all investments in equipment financed externally (i.e. not paid for out of equity capital, or out of return flows of capital from depreciation). Over the decades, leasing has become the number one alternative to the classical bank loan, and is now recognized as one of the key engines of innovation and economic growth in Germany.

TL;DR: In this paper , a multiscale texton broadcasting module is introduced to generate a broader range of textures, from those with regular structures to completely stochastic ones, and the proposed approach yields significantly better quality textures than the state of the art.
Abstract: We present a universal texture synthesis approach that incorporates a novel multiscale texton broadcasting module in the StyleGAN-2 framework. The texton broadcasting module introduces an inductive bias, enabling generation of a broader range of textures, from those with regular structures to completely stochastic ones. To train and evaluate the proposed approach, we construct a comprehensive high-resolution dataset, NUUR-Texture500, that captures the diversity of natural textures as well as stochastic variations within each perceptually uniform texture. Experimental results demonstrate that the proposed approach yields significantly better quality textures than the state of the art. The ultimate goal of this work is a comprehensive understanding of texture space.

TL;DR: A new dense multi-view registration technique for wide-baseline video/images that integrates a parametric optical flow-based approach with a sparse set of feature correspondences, based on a locally planar approximation of a nonplanar scene is presented.
Abstract: We present a new dense multi-view registration technique for wide-baseline video/images that integrates a parametric optical flow-based approach with a sparse set of feature correspondences, based on a locally planar approximation of a nonplanar scene. The proposed method can deal with illuminance variations between the views, which is critically important for wide-baseline applications. It differs from existing work on wide-baseline image registration in that it requires only image information and provides dense matching with-out computing any camera calibration matrices or performing any prior scene segmentation. These characteristics render the method suitable for practical deployment in visual sensor networks, towards which the current work is directed. We demonstrate the performance of the proposed method on simulated multi-view images of a virtual 3D world composed of piece-wise smooth textured surfaces, as well as real wide-baseline images of nonplanar textured surfaces.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: SPAdes as mentioned in this paper is a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E+V-SC assembler and on popular assemblers Velvet and SoapDeNovo (for multicell data).
Abstract: The lion's share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E+V-SC assembler (specialized for single-cell data) and on popular assemblers Velvet and SoapDeNovo (for multicell data). SPAdes generates single-cell assemblies, providing information about genomes of uncultivatable bacteria that vastly exceeds what may be obtained via traditional metagenomics studies. SPAdes is available online ( http://bioinf.spbau.ru/spades ). It is distributed as open source software.
