Nitrogen application often dramatically increases crop yields, but N needs vary spatially across fields and landscapes. Remote sensing collects spatially dense information that may contribute to, or provide feedback about, N management decisions. There is potential to accurately predict N fertilizer need at each point in the field. This would reduce surplus N in the crop production system witho...

Production rules and logic programs can be combined in a single logic-based framework. The framework gives both an operational and modeltheoretic semantics to production rules, as well as to logic programs extended with a database of facts that is modified by destructive assignment. The model-theoretic semantics is obtained by separating the production system working memory into facts and goals...

We aim at the realization of automatic contents production system of commentary soccer video based on digital shooting technique which is composed of digital camera work and digital switching technique. The digital camera work is defined as virtual panning and virtual zooming. the virtual panning is a video production technique of clipping a size fixed frame by controlling frame location on a h...

A real economic growth only comes from increasing quality and quantity of the factors of production. Most production systems produce items which are of imperfect quality. In a production/inventory situation items which are received or produced are not of perfect quality. Thus the presence of defects which is inevitable in a produced/ordered lot is sorted out by the process of screening. Handlin...

introduction: one of the main indicators in the scientific development of many countries is their scientific production. in this regard, universities and faculty members, as the most critical factors in research and scientific areas, play the most significant role. methods: the current study attempts to identify the critical factors and obstacles involved in the production of science at kermans...

this article has attempted to present a clear image of science production by the member states of the organization of islamic conference (oic) based on the essential science indicators (esi). esi indexes the most effective science productions of the world. the world bank, on the other hand, has classified the countries of the world according to their economic position. using the information acc...

background: along with the prospers of scientific production there is a need for measuring and evaluation of university’ s scientific productions by means of accepted international indices to make comparison between academic institutions. this study aims to evaluate the scientific production of faculty members affiliated to shahid beheshti university of medical sciences (sbmus) in web of scienc...

The science of polymers, more specifically, synthesis, characterization, and physicochemical properties in solutions, has wide application in the petroleum industry, which uses polymers as components of fluids or additives to correct problems that affect oil production and/or increase production costs. Polymers are utilized during all phases, from drilling to treatment of oil and water. Researc...

This study examines patterns of dynamic disciplinary knowledge production and diffusion. It uses a citation data set of Scopus indexed journals and proceedings. The journal-level citation data set is aggregated into 27 subject areas and these subjects are selected as the unit of analysis. A three-step approach is employed: the first step examines disciplines’ citation characteristics through sc...
