Heijunka is a key-element of the Toyota production system. It is used to level the release of production kanbans in order to achieve an even production program over all possible types of products thus reducing or eliminating the bullwhip effect. In this paper the dependencies between the parameters of the levelling process and the requirements in finished goods stocks are derived, resulting in ...

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...

Materials and methods To investigate the functionality of the CD38-HLA-DR+ profile, we compared it with the classically activated phenotype CD38+HLA-DR+ by evaluating several qualitative parameters: (1) activation measured by CD69, CD25, CD71, CD40 and Ki67 expression, (2) memory parameters measured by proliferation capacity, CD127 and Bcl-2 expression, cytokine production measured by IL-2 prod...

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...

BACKGROUND Staphylococcus epidermidis (SE) is a nosocomial pathogen that causes catheter-associated bacteremia in the immunocompromised, including those at the extremes of age, motivating study of host clearance mechanisms. SE-derived soluble components engage TLR2; but additional signaling pathways have also been implicated, and TLR2 can play complex, at times detrimental, roles in host defens...

In this paper we discuss an often neglected component of robot reasoning and decision making, which is temporal reasoning. We provide a practical system for temporal reasoning within the framework of production systems and show its application to robot problems. illustrate the use of the temporal production system for that purpose. 2 Temporal Production System In the proposed system the product...

Sunflower is one of four main annual oil plants that cultivated in oil and nut varieties. This plant as an important and industrial food product and because of nutritional features and the potential for earning exchange has become a valuable product in foreign and inner markets and has a special position in agricultural sector. Khoy, by producing 40 percent of sunflower productions of country a...

This study assessed of youth involvement in agricultural production in Sabon Gari Local Government Area. The data used for this study were collected using interview schedule administered to 112 respondents who were selected through multi-stage sampling procedure. Descriptive statistics such as frequency, percentages and means were used to analyze the data. The result revealed that majority (95....
