to study the phenotypic and genotypic diversity of some important agronomic traits associated with yield in white beans, 30 genotypes of white bean were evaluated using a randomized complete block design with four replications in two environments under water stress and non stress conditions. analysis of variance for most of the traits showed significant differences among genotypes, indicating t...

We consider an exponentially stable closed loop interconnection of a continuous linear plant and a continuous linear controller, and we study the problem of interconnecting the plant output to the controller input through a digital channel. We propose a family of “transmission-lazy” sensors whose goal is to transmit the measured plant output information as little as possible while preserving cl...

Vermiculite was used to develop inorganic carrier-based formulations of fluorescent pseudomonad strains R62 and R81. The effect of bio-inoculation of fluorescent pseudomonad strains R62 and R81 (plant growth promoting and biocontrol agent) on growth responses of Vigna-mungo under field condition was enumerated. The combined bioinoculation of these two organisms in a formuation increased the pod...

this experiment was carried out to investigate the effect of plant density on growth and seed yield of wheat (kodasht cultivar) under saline soils and rainfed condition inanbarolum region of golestan province in 2008-09. an experiment was conducted in three fields with different salinities (6.73, 9.34 and 11.63 ds m-1) based on randomized complete blocks design. treatments were four plant densi...

One of the most interesting questions concerning hierarchical control of discrete-event systems with partial observations is a condition under which the language observability is preserved between the original and the abstracted plant. Recently, we have characterized two such sufficient conditions—observation consistency and local observation consistency. In this paper, we prove that the condit...

for a suitable irrigation programming and an efficient management, crop coefficient determination for different plant growth stages are necessary. in this investigation water requirement, single and dual crop coefficient of rosmarinus officinalis l. was determine by drainable lysimeter in a semi-arid climate condition. by using of drainable lysimeter, the exact water requirement and also kc val...

Maintenance has gained in importance as a support function for ensuring equipment availability, quality products, on-time deliveries, and plant safety. Cost-effectiveness and accuracy are two basic criteria for good maintenance. Reducing maintenance cost can increase enterprise profit, while accurate maintenance action can sustain continuous and reliable operation of equipment. As instrumentati...

We consider the passivity analysis and passivation problems for event-triggered feedback interconnected systems. Based on the location of the event-triggered samplers, we consider two event-triggered control schemes respectively: event-triggered sampler of plant output and event-triggered sampler of controller output. For both schemes, we first derive the conditions to characterize the level of...
