Inductive computing, comprised of machine learaing, data mining, and knowledge discovery, seeks to extract causal patterns from data. Meta-patterns are patterns of extrax:ted patterns. The meta-pattern we study here is the cycle. In this paper, we illustrate the ubiquity of cycles anti argue that as responsible knowledge engineers, we need to identify and actively seek cycles out of data. We pr...

Introduction: Fruit polysaccharides, essential health factors in foods, are widely present in edible fruits. Several methods for isolation of polysaccharide are available. Microwave Assisted Extraction (MAE) method is extensively used for separation of polysaccharides. Only little information is available about Psidium guajava L. Fruit Polysaccharide (PFP) and its extraction methods. Objective:...

Focused open-vessel microwave-assisted extraction (FOV-MAE), closed-vessel microwave-assisted extraction (CV-MAE), and accelerated solvent extraction (ASE) were used for extraction before determination of organochlorine compounds (polychlorinated biphenyls, DDT, toxaphene, chlordane, hexachlorobenzene, hexachlorocyclohexanes, and dieldrin) in cod liver and fish fillets. Wet samples were extract...

in arid, semiarid, and mediterranean climates, particularly in west asia and north africa, farmers face limited water resources and must develop irrigation management methods to increase crop production while reducing water use. this study examined methods to reduce irrigation water loss and increase maize water productivity at safiabad agricultural research center in dezful, iran in 2007 and 2...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

The knowledge and the forecast of the parameters which rule the down flow models in oil extraction and transport are today of paramount importance. In particular the extracted oil is mixed with water and gas in rates, which differ not only from different wells, but also on the same well during its life. The main problems involved with the measurement of the flow rates are: well exhaustion, crit...

introduction: accumulation of free radicals could lead to permanent oxidative destruction of organisms by attacking macromolecules and organelles of the body, thus causing organism aging, fatigue and degenerative diseases. therefore, discovering and developing safe and non-toxic natural antioxidants has been an interesting topic in recent decades. compared to synthetic antioxidants, extracts fr...

abstract a model based on fuzzy logic has been developed to simulate the distribution pattern of a single sprinkler. a nelson r3000 sprayer with rotator pad and water application angle of 360o which is one of the most common types of center pivot and linear move sprinklers was selected. several field experiments according to the iso-8026 and asae-s398.1 standards were performed to assess the wa...

abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...
