Let a,b∈R , with a≠b . The harmonic, logarithmic, and arithmetic means of a b are respectively defined by H(a,b)=21a+1b=2aba+b,L(a,b)=b−a ln b− ln a A(a,b)=a+b2 .Theorem. For 0<a<b,2a+b< ...

the present study aimed at presenting a model of knowledge management success in order to increase organizational creativity and learning in the ministry of sport and youth of iran. the study was a survey which used a correlation method. the statistical population consisted of expert staff of the ministry and 160 subjects were randomly selected by stratified random sampling method. a research-m...

Hippocampal-dependent learning and memory processes are associated with theta frequency rhythmic activity. Interneuron and pyramidal cell network interactions underlie this activity, but contributions of interneuron voltage-gated membrane conductances remain unclear. We show that interneurons at the CA1 lacunosum-moleculare (LM) and radiatum (RAD) junction (LM/RAD) display voltage-dependent sub...

The performance of Neural Networks (NN) depends on network structure, activation function and suitable weight values. For finding optimal weight values, freshly, computer scientists show the interest in the study of social insect’s behavior learning algorithms. Chief among these are, Ant Colony Optimzation (ACO), Artificial Bee Colony (ABC) algorithm, Hybrid Ant Bee Colony (HABC) algorithm and ...

  Background: Because of the importance of community health and the growing need for health care Health organizations have expanded their scope and with an entrepreneurial approach seeking to upgrade their performance. Knowledge is the most important capital of organizations and key factor in economics. The purpose of this study was to investigate the effect of knowledge management on organizat...

A four-year trial was initiated in January 2000 to evaluate forage production, basal cover, and persistence of endophyte-infected tall fescue (IF; Festuca arundinacea Schreb.), endophyte-free tall fescue (FF), or orchardgrass (OG; Dactylis glomerata L.) overseeded into dormant common bermudagrass [Cynodon dactylon (L.) Pers.] for spring-calving cows. The FF and OG pastures were managed with eit...

OBJECTIVES The objective of this article was to compare the costs and cost-effectiveness of the two most prominent types of case management in the Netherlands (intensive case management and linkage models) against no access to case management (control group) for people with already diagnosed dementia and their informal caregivers. METHODS The economic evaluation was conducted from a societal ...

Management of wild peppers in Mexico has occurred for a long time without clear phenotypic signs of domestication. However, pre-domestication management could have implications for the population's genetic richness. To test this hypothesis we analysed 27 wild (W), let standing (LS) and cultivated (C) populations, plus 7 samples from local markets (LM), with nine polymorphic microsatellite marke...

Network and system security is of vital importance in the present data communication environment. Hackers and intruders can create many successful attempts to cause the crash of the networks and web services by unauthorized intrusion. New threats and associated solutions to prevent these threats are emerging together with the secured system evolution. Intrusion Detection Systems (IDS) are one o...
