Numerical Solution of Stochastic Hyperbolic Equations
Necmettin Aggez,Maral Ashyralyyewa
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/824819
Abstract: A two-step difference scheme for the numerical solution of the initial-boundary value problem for stochastic hyperbolic equations is presented. The convergenceestimate for the solution of the difference scheme is established. In applications, the convergence estimates for the solution of the difference scheme are obtained for different initialboundary value problems. The theoretical statements for the solution of this differencescheme are supported by numerical examples.

Allaberen Ashyralyev,Necmettin Aggez
Discrete Dynamics in Nature and Society , 2011, DOI: 10.1155/2011/562385
Abstract: The stable difference schemes for the approximate solution of the nonlocal boundary value problem for multidimensional hyperbolic equations with dependent in space variable coefficients are presented. Stability of these difference schemes and of the first- and second-order difference derivatives is obtained. The theoretical statements for the solution of these difference schemes for one-dimensional hyperbolic equations are supported by numerical examples.
An Experiment in Use of Brain Computer Interfaces for Cognitive Researches  [PDF]
Necmettin Firat Ozkan, Emin Kahya
International Journal of Intelligence Science (IJIS) , 2015, DOI: 10.4236/ijis.2015.52008
Abstract: Brain-Computer Interfaces (BCIs) are systems that are primarily developed for use of paralyzed people. Although their main aim of use has a medical point of view, they can also be used for different aims such as entertainment and cognitive researches. Since BCI systems have specific brain potentials (P300, steady state evoked potential) and ERD/ERS (Motor Imagery), they are also flexible tools for cognitive science. In this study, an experiment was conducted with 30 participants. Each participant completed two tasks through a BCI and filled NASA-TLX forms. The results were analyzed using paired t-tests to see whether BCI tasks are significantly different in terms of creating cognitive load. The results showed that NASA-TLX scores of the BCI tasks were significantly different and these systems can be considered for estimating cognitive states studies.

Necmettin ?eker
Igdir University Journal of Social Sciences , 2012,
Abstract: This study is about the short descriptions of mystical concepts used in basic mysticism books of the classical times and the verses and particularly the hadithes these concepts were based upon. Our goal is to determine the resources on which the mysticism teachings with significant contributions to slamic thought system were grounded and to determine the relationships built. In this context, basic mystical concepts taking place in the first-period classical mysticism resources have been detected, short mystical descriptions of them have been made and the comments on the relationships of them with the Quran verses and hadithes they were grounded have been evaluated.
Religious Foundations of Statements and Attitudes that Signify Ecstatic Utterances

Igdir University Journal of Social Sciences , 2012,
Abstract: Statements and attitudes called ecstatic utterance in mystical language and happened unconsciously in overflowing from the dab of Sufism have been the matter of a lot debates until today. It is difficult to know the true meanings and purposes of such statements, which are not possible both proving and refutation them, for someone else from who tell it. It is believed that these statements have been said in recovery, ecstasy, lost and supremacy; such that since they have outwardly been seemed contrary to religious rules, wherefore these aspects many of the Sufis have been accused of unbelief, furthermore, they have been given fatwas to be murdered. For all that, the dab of Sufism has been developed some solutions in order to get rid of these imputations and to defend the aforesaid statements. One of these solutions is the effort of attributing the statements and attitudes that signify ecstatic utterances to verses and hadith, and of approving to them by verses and hadith. But verses and hadith they have used, except for spot of them, had no concern with aforesaid statements.
TRILOGY- ANCIENT AGE, MIDDLE AGE AND NEW AGE- IN THE DIVIDING HISTORY INTO AGES AND THE EUROCENTRIC HISTORY CONSTRUCTION
Necmettin ALKAN
Journal of International Social Research , 2009,
Abstract: one of the most significant paradigms or preassumptions of the science of history. Both academic and amateur historians are dividing historical period into Ancient Age, Middle Age and New Age by starting from these preassumptions. Professional specializations in the field of history are being prepared according to this, too.The three system which became common part of the human history was constituted in a long period. Aurelius Augustinus (354-4309), the father of Catholic Church, divided historical period according to the Bible for the first time. Christian religious after him continued this tradition and matured this thought as before Christ and after Christ by centering on Jesus. German theologian and historian Christoph Cellarius (1634-1707) who started from this tradition and inheritance made the existing trilogy by giving the last form to it. Almost everybody who was effective upon arising of the trilogy were Catholic and Protestant ecclesiastics. While these ecclesiastics were constituting the system, they preferred the event which were connected with Christian religion and the geography of Europe. Thus, one of the pillars of the construction of “Eurocentric History” which is present came into being. This scheme which is “Clerical”, “Regional” and “Arbitrary” is not relevant especially with the history of the human being and the history of the nations which are not Christian and from West Europe. It is not relevant with Turkish History and The History of Islam. The History of Turkish-Islam which is aimed by editing it in this form is made swallow and became poor in this way. As a result of this, Turkish historians should work by putting on the agenda a novel dividing of ages relevant to their own history.

Mevlut Turk,Necmettin Celik
Journal of Biological Sciences , 2006,
Abstract: The purpose of this research was to evaluate phenotypic correlation coefficients between seed yield and some yield components and to determine the direct and indirect effect of 9 components on seed yield in sainfoin (Onobrychis sativa L.). The research was conducted at the Agricultural Research and Experiment Center of Agriculture Faculty, Uludag University in 2000-2003. The field experiments were established in a split plot design with four replications. Seed yield, plant height, raceme number per plant, stem number per m2, raceme number per m2 , fruit number per raceme, fruit weight per raceme, fruit number per plant, fruit weight per plant and 1000-fruit weight were determined. The data obtained over 3 years were combined. According to results of this research, seed yield was positively and significantly correlated with raceme number per plant (r = 0.266**), fruit number per raceme (r = 546**), fruit weight per raceme (r = 538**), fruit number per plant (r = 0.495**), fruit weight per plant (r = 0.490**) and 1000-fruit weight (r = 0.602**), while seed yield was negative and significantly correlated with stem number per m2 (r = -0.353**) and raceme number per m2 (r = -0.305**). Path coefficient analyses revealed that fruit number per plant (2.2757 and 28.50%) had the highest positive direct effect, followed by fruit weight per raceme (1.6989 and 20.74%), on seed yield, while fruit weight per plant showed the highest negative direct effect (-2.3369 and 28.59%).
