Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...

abstract soil moisture measurement and control is a base to employ optimal management methods for reducing water consumption and improvement of the product quality. the main objective of this research was increasing the efficiency of water consumption in a greenhouse condition. this study was carried out in the framework of three treatments of soil potential including irrigation at 40, 60 and 8...

This paper proposes a method to autonomously select stable visual landmarks from observed features by stereo vision and a given 2D obstacle map. The robot selects as stable landmarks vertical line segments which are distinct and on a vertical plane, because they are expected to be observed reliably from various viewpoints. Due to the vision and motion error of the robot, the observed feature po...

drought stress is one of the serious problems that restricted agronomic plant production worldwide. inmolecular level, the harmful effect of drought stress is mostly caused by producing of large amount ofreactive oxygen species (ros). catalase and metallothionein genes have a crucial role to mope the hydrogenperoxide (h2o2) resulting reducing oxidative damage. in this research the gene expressi...

effects of homogenization sequence (before or after heating) and homogenization pressure (0, 50, or 150 bar) were studied on the certain textural properties of milk-based creamy dessert including hardness, surface tension and syneresis. also, the microstructure of the treatments was analyzed using scanning electron microscopy (sem). homogenization at 50 bar after heating led to the highest hard...

drought and salinity are two important environmental stresses limiting the crop production. in order to study the influence of drought and salinity stresses on germination characteristics of marshmallow plant seeds, two separate experiments were conducted based on completely randomized design with four replications in controlled conditions. drought stress levels were 0, -2, -4, -6 and -8 bar in...

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...
