THE EFFECT OF ARGUMENTATION BASED TEACHING ON THE UNDERSTANDING LEVELS OF PRIMARY SCHOOL STUDENTS ABOUT THE NATURE OF SCIENCE
(HACETTEPE UNIV, 2013)
Researches showes that primary school students have insufficient understanding of the nature of science. Recent studies emphasise the importance of scientific argumentation. The aim of this research is to investigate the ...
Diagnosis of Pathology on the Vertebral Column with Backpropagation and Naive Bayes Classifier
(IEEE, 2013)
Minimizing human errors in diagnosis is one of the most important aims of Computer-Aided Diagnosis (CAD) systems. CAD software is the software helping radiologists, specialist doctor for detect abnormality on medical views ...
Control of Traffic Intensity in Hyperexponential and Mixed Erlang Queueing Systems with a Method Based on SPRT
(HINDAWI LTD, 2013)
The control of traffic intensity (rho)is one of the important problems in the study of queueing systems. Rao et al. (1984) developed a method to detect changes in the traffic intensity in queueing systems of the M/G/1 and ...
RAD-circle plus-SUPPLEMENTED MODULES
(OVIDIUS UNIV PRESS, 2013)
In this paper we provide various properties of Rad-circle plus-supplemented modules. In particular, we prove that a projective module M is Rad-circle plus-supplemented if and only if M is circle plus-supplemented, and then ...
