in order to investigate the effects of weeds interference on yield and yield components of different genotypes of common bean, an experiment was conducted as split plot based on randomized complete block design with three replications at agricultural research station of tabriz university, in 2011. the main plots were eight genotypes of different types of common bean including red bean, (cv. gho...

Real world applications that deal with information extraction, such as business intelligence software or sensor data management, must often process data provided with varying degrees of uncertainty. Uncertainty can result from multiple or inconsistent sources, as well as approximate schema mappings. Modeling, managing and integrating uncertain data from multiple sources has been an active area ...

The objective of this thesis is to explore ways of describing agents in logical theories. The contribution is that the logical theories we build are a generalised form of logic programs. Like normal logic programs, these theories have an intuitive declarative reading and a procedural interpretation to guide the implementation of automatic devices and software. Both human beings and machines can...

An important research area in the field of AI is the design of intelligent agents acting in a changing environment. Research in this area has led to development of agent architectures that support various tasks such as planning, diagnosis, learning etc. One such architecture is based on the agent repeatedly executing the observe-think-act-loop (Baral and Gelfond 2000; Kowalski and Sadri 1999). ...

A computee is an autonomous computational entity that operates in an open and dynamic environment. This report proposes a formal framework for computees, called KGP (Knowledge, Goals, Plan), that synthesises their reasoning and sensing capabilities into a model for their operation. Within this model the computee is able to reason about goals and plans and to execute its plans depending on the s...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...
