Method of additional argument in problems of optimal control

Ramiz RAFATOV

The problem of control of the process described by the nonlinear differential equation with partial derivatives of the first order, with conditions at t 0 and in a sequence n of points x1 < x2 ... < xn is solved. The criterion of quality of control is the integrated quadratic functional, which depends on a final state of system and set n of controlling parameters. The method of increment of functional is applied to reception of conditions of optimality, and the method of additional argument (MAA) is applied for the decision of the nonlinear equations with partial derivatives.

Amino Acid and Fatty Acid Profile of the Mare's Milk Produced on Suusamyr Pastures of the Kyrgyz Republic During Lactation Period

Ayçürök MACİTOVA | Asılbek KULMIRZAYEV | Cıldızay ÖZBEKOVA | Aybek BODOŞOV

The high nutritional and health-promoting properties of kymyz, a traditional drink of nomads produced from mare's milk, are well-known and reported in literature. The composition of mare's milk is significantly different from that of cow and other ruminants. Fatty acid composition and amino acid profile of mare's milk produced at Suusamyr pastures of Kyrgyzstan were studied during four lactation months (May, June, July and August). The amino acid composition was determined by precolumn derivatization with diethyl ethoxymethylenemalonate (DEEMM) in high-performance liquid chromatography (HPLC) ...More

A novel sensitive Cu(II) and Cd(II) nanosensor platform: Graphene oxide terminated p-aminophenyl modified glassy carbon surface

Ali Osman SOLAK

Graphene oxide (GO) based glassy carbon (GC) electrode has been prepared. Firstly, p-nitrophenyl (NP) modified GC (NP/GC) electrode was prepared via the electrochemical reduction of its tetraflouroborate diazonium salt. After the formation of NP/GC electrode, the negative potential was applied to NP/GC electrode to reduce the nitro groups to amine. p-Aminophenyl (AP) modified GC (AP/GC) electrode was immersed into a graphene oxide solution containing 1-ethyl-3(3-(dimethlyamino)propyl)-carbodiimide. Hence, we constructed GO terminated AP modified GC (GO/AP/GC) electrode. NP/GC, AP/GC and GO/AP/ ...More

The Impact of Self-efficacy Perception on Reading Comprehension on Academic Achievement

Kadir YOĞURTÇU

Reading comprehension requires the conscious and cognitive efforts of individual. In this regard, an individual should set up concern on what they read and previous information they have according to reading purposes. As a result of this cognitive effort one can restructure the intellectual development. As well there are interesting approaches improved by combining of the high-level cognitive functions such as interpretation and synthesis with social interactions in the aspect of reading comprehension. The self-efficacy beliefs scale developed by Bandura was adapted to the pedagogy field and a ...More

Kadir YOĞURTÇU

The main objective of this article is to study self-sufficiency level of foreign language teachers in Foreign Languages High School of Kyrgyzstan-Turkey Manas University (KTMU). In this regard the significance of age, gender and nationality on self- efficacy is investigated. This study was conducted with the participation of Turkish, Kyrgyz, Russian and English teachers (citizens of Kyrgyzstan and Turkey) of High School of Foreign Languages, working in fall semester of 2011-2012 academic years. The total number of respondent is 110. The data obtained through Ohio Teacher Efficacy Scale (2001), ...More

Tourism Sector in Order to Recovering From the Recession: Comparison Analyses for Turkey

Muhsin HALİS

2008 economic crisis hit very hard many sectors globally, beside tourism, too. According to the economical and financial reports, the demand of hotel & restaurant industry declined sharply, and as a result of that situation tourism revenues had been affected negatively. Turkey was one of the few destination, which had a growing at the international tourist arrivals despite the 2008 crisis. Although the tourism revenues declined, but it was little while comparing with its competitors.

Method of spherical harmonic series in the problem of minimization of atmosphere pollution by fractions of harmful admixtures

Ramiz RAFATOV

The problem of minimization of atmosphere pollution by fractions of harmful admixtures is studied. It is supposed that a controlled object is described by non-stationary integral–differential transfer equation with special boundary conditions and control parameters, which are included in the right part of equation as delta-functions. Minimized integral quadratic functional characterizes energy expenditure for control and depends on the average squared deflection of fraction concentration from the desired final state. Optimal conditions are obtained with the help of Pontryagin’s maximum princip ...More

Preparation of stabilized silver and tin nanocomposites by electrical discharge

Emil ÖMÜRZAK

In this study silver and tin nanocomposites were synthesized by electro spark dispersion in ethanol. Resulting nanocomposite was characterized by using the powder x-ray diffraction and emission scanning electron microscopy. It was found by X-ray phase analysis that the product obtained by electro spark joint dispersion of silver and tin in ethanol consists of two phases: Ag3Sn and beta-Sn. The results of processing SEM micrographs of the product of the Ag-Sn system show that the obtained phases are spherical nanostructures with sizes of 30-60 nm. This size of nanostructures was associated wit ...More
