Mosaic techniques have been used to obtain images with a large field of view from video sequences by assembling individual overlapping images. In existing methods of mosaic construction only consecutive frames are aligned. Accumulation of small alignment errors occur, and in the case of the image path returning to a previous position in the mosaic (looping path), a significant mismatch between ...

Analytical tools in business management are understood as a combination of information technologies and quantitative methods used to assist stakeholders to make better decisions. The contemporary business environment is dramatically changing by the massive accumulation of data. Now, as never before, the use of analytical tools must be expanded to take advantage of this growing digital universe....

he United Nations (UN) Millennium Deve lopmen t Goa ls (MDGs) represent a path-breaking global effort to combat poverty and human deprivation. In comparison with prior attempts, the MDGs are unique in symbolising the first ever global long-term agreement to combat the multiple dimensions of poverty (Sumner & Tiwari 2009), while providing national policymakers with comprehensive and timebound go...

We report the finding of two large-scale structures in a wide-field (40 × 35 arcmin) optical (V and I-band) imaging survey of a field towards two known concentrations of quasars and Mg ii absorbers at z ≃ 0.8 and z ≃ 1.2. We are able to select high-redshift (0.6∼z∼1.3) early-type galaxies as those redder than the cluster red sequence at z = 0.5 and having I < 23.5. Through comparison with a 35 ...

We derive the luminosity functions in three bands (BVR) for the rich galaxy cluster ABCG209 at z=0.21. The data cover an area of ∼ 78 arcmin in the B– and R–band, while a mosaic of three pointings was obtained in the V–band, covering an area of approximately 160 arcmin. The galaxy sample is complete to B = 22.8 (Ngal = 339), V = 22.5 (Ngal = 1078) and R = 22.0 (Ngal = 679). The luminosity funct...

This paper reviews the recent empirical literature on long-run growth to determine what factors influence growth in total factor productivity (TFP) and whether there are any channels of influence that should be added to standard models of long-run growth. Factors affecting productivity fall into three general categories: physical capital, human capital, and innovation (including other factors t...

The digital world generates an incredible accumulation of information. This results in redundant, complementary, and contradictory information, which may be produced by several sources. Applications as multidocument summarization and question answering are committed to handling this information and require the identification of relations among the various texts in order to accomplish their task...

Ice-core data are the only source of ice response on timescales of hundreds to thousands of years, which is necessary to describe polar ice-sheet flows and their interaction with changing climatic conditions. Ice properties, such as a grain growth relation, require knowledge of each ice particle’s history since first deposited at the surface, and not simply the present core state. This study is...

To deal with tough issues in knowledge management, the paper reexamines knowledge structure and has proposed a novel knowledge communication model based on the oriental cultural foundation. Knowledge discovery is not a simple addition or accumulation of information, but needs a feasible structural description. As an oriental approach, the paper constructs the structure on the bases of unity of ...

New models for evolutionary processes of mutation accumulation allow hypotheses about the age-specificity of mutational effects to be translated into predictions of heterogeneous population hazard functions. We apply these models to questions in the biodemography of longevity, including proposed explanations of Gompertz hazards and mortality plateaus.
