Many countries are facing a challenging transition toward more sustainable energy systems, which produce more renewables and consume less energy. The latter goal can only be achieved through a combination of efficiency measures and changes in people’s lifestyles and routine behaviors (i.e., sufficiency). While research has shown that acceptance of technical efficiency is relatively high, there ...

The researchers currently have a new tool for dealing with the solution of biomedical problems: the Microarrays. These devices support the study and the acquisition of information related to many genes at the same time by means of a unique experiment, providing multiple potential applications such as mutation detection of microorganism identification. Some of the problems that exist when workin...

Most halftoning techniques have been primarily concerned with achieving an accurate reproduction of local grayscale intensities while avoiding the introduction of artifacts. A secondary concern in halftoning has been the preservation of edges in the halftoned image. In this paper, we will introduce a new halftoning technique that utilizes a bandpass pyramid to achieve an accurate reproduction o...

If digital libraries are to achieve their full potential, they need to be usable and used – by people for whom information retrieval is not generally the main goal. In this paper, we outline various views of ‘usability’ and how they apply specifically to digital libraries. There are great challenges to integrating user perspectives with technical developments, in terms of understanding those us...

Due to their representative power, structural descriptions have gained a great interest in the community working on graphics recognition. Indeed, graph based representations have successful been used for isolated symbol recognition. New challenges in this research field have focused on symbol recognition, symbol spotting or symbol based indexing of technical drawing. When they are based on stru...

Finally, it sample of Illinois grain farms using the corshould be noted that the method developed rected ordinary least squares method. Instead here can be easily applied to farm data ...

Boundary labeling is a relatively new labeling method. It can be useful in automating the production of technical drawings and medical maps, where it is common to explain certain parts of the drawing with text labels, arranged on its boundary so that other parts of the drawing are not obscured. In boundary labeling, we are given a rectangle R which encloses a set of n sites. Each site si is ass...

Drawing on a 28-item survey, this article reports the editorial experiences of 173 lead authors of articles published in the Academy of Management Journal and Academy of Management Review, over the period 1999 to 2001, to explore some relatively new dynamics that have changed the character of the manuscript review process and given rise to a mounting debate over the proper roles of authors, ref...

METAPOST is a tool especially well-suited for the inclusion of technical drawings in a document. In this article, we show how METAPOST can be used to represent objects in space and especially how it can be used for drawing geometric constructions involving lines, planes, as well as their intersections, orthogonal planes, etc. All the features belong to a new METAPOST package aimed at all those ...

This paper argues that the evidence-based policy movement needs to supplement its current evaluation-based approach with an approach that uses data at a much higher frequency to improve the administration and impact of government-funded social service programs. Doing so offers the best chance of making significant progress in ameliorating challenging social problems. The paper describes how an ...
