Ruhi, Faculty of Engineering, Bahçeşehir Üniversitesi, Istanbul, TurkeyMeeting customer needs in a limited time schedule always require fast, cheap and highly accurate modelling tools in automotive industry. Moreover, in order to be competitive in international markets, companies try to simulate the climate conditions of the customer' s home country at their research and development laboratories. The climate and the seasonal outdoor conditions are the main input data for thermal comfort design. Since it is not practical and cheap to perform experiments in real conditions, companies prefer to use computer aided engineering design tools to simulate the heating and cooling scenories inside the bus cabins. In this investigation, the authors propose an efficient computer algoritm for the fast calculation of the temperature field inside a bus cabin based on a lumped parameter model. It is demonstrated that the algoritm is numerically capable of producing results in agreement with the experimental data. © ECCOMAS. © 2014 Elsevier B.V., All rights reserved.Publication Metadata only Effects of diffusivity on the predicted hollow fiber biofilm reactor performance(C S R E A PRESS, 2000) Yalçin, S; Valafar, F; Bahcesehir UniversityConsiderable modeling work has been done to calculate the performance of hollow fiber biofilm reactors (HFBR's). The performance of the HFBR is controlled by the biological phase (biofilm). Previous investigations of biofilm structure showed that biofilms are heterogeneous and consist of voids, and cell clusters. The biofilm activity can be modeled using the diffusion reaction model. The main design parameter in diffusion and reaction model is the effective diffusivity in biofilms. Recent studies have shown that the effective diffusivity varied in biofilms and is controlled by the biofilm heterogeneity This variation may influence the predicted activity oft he HFBRs. The existing biofilm models do not include variable effective diffusivity. The goal of this study was to compare the predicted performance of HFBR by employing 1) position dependent and, 2) constant effective diffusivity. The percentage difference between predicted activities, employing variable, and constant effective diffusivity, was approximately zero for biofilm thicknesses less than 50 mum. However, the percentage difference is significantly increased for biofilms thicker than 50 mum. The employment of constant or variable effective diffusivity in the model does not influence the predicted results for thinner biofilms. However, increased biofilm thickness significantly influences the predicted activity of the HFBR. Ir was concluded that for thicker biofilms, a variable effective diffusivity should be used in the model solutions.Publication Open Access The synthesis of novel crown ethers, part VII [1].

The original products were identified by high resolution EI-mass spectra as well us IR, 1H-NMR and 13C-NMR spectroscopy. The 1 : 1 binding constants of Mg2+, Li+, Na+ and K+ with the coumarin-benzocrowns were estimated using fluorescence emission spectroscopy in acetonitrile. The complexing enhanced quenching fluorescence spectra (CEQFS) and complexing enhanced fluorescence spectra (CEFS) exhibited the ion binding powers due to cationic recognition rules of the macrocycles. © 2020 Elsevier B.V., All rights reserved.Publication Metadata only Economic variables and electricity consumption in Northern Cyprus(Elsevier Ltd, 2001) Egelioǧlu, Fuat; Mohamad, Abdulmajeed Abd; Güven, Halil M.; Egelioǧlu, Fuat, Department of Mechanical Engineering, Eastern Mediterranean University, Famagusta, Turkey; Mohamad, Abdulmajeed Abd, Department of Mechanical Engineering, Eastern Mediterranean University, Famagusta, Turkey; Güven, Halil M., Bahçeşehir Üniversitesi, Istanbul, TurkeyThe influence of economic variables on the annual electricity consumption in N. Cyprus for the period of 1988-1997 has been investigated. Utilising historical energy consumption, historical economic databases and multiple regression analyses, it was found that the number of customers, the price of electricity and the number of tourists correlate with the annual electricity consumption. The annual energy consumption was strongly related to the number of the customers, with adjusted R2 equal to 0.906 and 0.930 if the price of electricity and the number of tourists were included in the model. The results indicate that the model using the number of customers, the number of tourists and the electricity prices as regressors has very strong predictive ability and can be used to forecast future annual electricity consumption. © 2001 Elsevier Science Ltd.

I paid special attention to human capital accumulation and international trade environment and emphasized their spillover effects on growth and convergence among countries. I employed a technique using a cross-sectional and time series panel. The estimations in my empirical models were done using the nonlinear least-squares method in which I applied a dynamic procedure for an economy along its balanced growth path. I arrived at mixed results. The empirical results show that international spillover effects of human capital accumulation and intermediate goods production have positive and significant effects on the growth process of a nation. The national level of human capital, however, has negative and insignificant effects on this process. © 2018 Elsevier B.V., All rights reserved.Publication Metadata only Reliability analysis in N-version programming with dependent failures(2001) Ege, Mustafa; Eyler, M. Akif; Karakaş, M. Ümit; Ege, Mustafa, Department of Computer Engineering, Hacettepe Üniversitesi, Ankara, Turkey; Eyler, M. Akif, Department of Computer Engineering, Marmara Üniversitesi, Istanbul, Turkey; Karakaş, M. Ümit, Department of Computer Engineering, Bahçeşehir Üniversitesi, Istanbul, TurkeyIn fault-tolerant software, to enhance the reliability, one of the major approaches is N-version programming. The modeling studies provided in literature help us to understand under which conditions these approaches increase the software reliability. In this paper, the models given in literature for N-version programming are reviewed. We discuss the deficiency in one of these models trying to improve it to agree with another independent reliability model. Furthermore, we examine how we can combine the dependency concept with the independent reliability model and the subject of how we can extend it for N value. By taking into consideration the dependent failure behavior, a dependent failure parameter is introduced to the reliability model in case the events are /spl alpha/-dependent. Here, /spl alpha/ measures the similarity percentage of the input sets on which each pair of versions fail. © 2001 IEEE. © 2013 Elsevier B.V., All rights reserved.Publication Metadata only Turkish women's magazines: The popular meets the political(Elsevier Ltd, 2001) Kirca, Süheyla; Kirca, Süheyla, Faculty of Communication, Bahçeşehir Üniversitesi, Istanbul, TurkeyThis article focuses on the way concepts of feminism and femininity, often considered oppositional, intersect within two contemporary Turkish women's magazines, Kim and Kadinca.

There are considerable amount of study to predict hollow fiber biofilm reactor activity. However, most of them do not consider biofilm heterogeneity. The goal of this study was to develop an advance mathematical model for a hollow fiber biofilm reactor to predict effectiveness factor and calculate limiting conditions. We improved previously developed model of hollow fiber biofilm reactor by our research group. We used a diffusion reaction model of biofilm by employing variable effective diffusivity, radial flow rate, biofilm thickness and density. The solution of the model showed that glucose consumption rate in hollow fiber biofilm reactor increased with increased glucose concentration in the lumen. However, we did not observe classical behavior of effectiveness factor for our system. At low glucose concentrations (<20 mg/L), the effectiveness factors are increased with decreased glucose concentrations. For glucose concentrations higher than 20 mg/L, effectiveness factors increased with increased glucose concentrations. The increased radial flow velocity in the lumen increased effectiveness factors. At low flow velocities (<0.5 x 10(-5) cm/s) effectiveness factor did not vary with flow velocity, in the lumen. However, for increased flow velocities (>0.5 x 10(-5) cm/s) effectiveness factor increased. According to our model solution, we concluded that to increase effectiveness of hollow fiber biofilm reactor it is required to increase the lumen glucose concentration or radial flow velocity in the lumen.Publication Metadata only Economic variables and electricity consumption in Northern Cyprus(PERGAMON-ELSEVIER SCIENCE LTD, 2001) Egelioglu, F; Mohamad, AA; Guven, H; Eastern Mediterranean University; Bahcesehir UniversityThe influence of economic variables on the annual electricity consumption in N.

Helium is used as coolant, and SiC is used as cladding material to prevent fission products from contaminating coolant and direct contact fuel with coolant in the blanket. Calculations of neutronic data per DT fusion neutron are performed by using SCALE 4.3 Code. M (energy multiplication factor) changes from 1.480 to 2.097 depending on the fuel types in the blanket under resonance-effect. M reaches the highest value in the blanket fueled with UN. Therefore, the investigated reactor can produce substantial electricity in situ. UN has the highest value of 239Pu breeding capability among the uranium fuels whereas UO2 has the lowest one. 239Pu production ratio changes from 0.119 to 0.169 according to the uranium fuel types, and 233U production values are 0.125 and 0.140 in the blanket fueled with ThO2 and ThC under resonance-effect, respectively. Heat production per MW (D,T) fusion neutron load varies from 1.30 to 7.89 W/cm3 in the first row of fissile fuel breeding zone depending on the fuel types. Heat production attains the maximum value in the blanket fueled with UN. Values of TBR (tritium breeding ratio) being one of the most important parameters in a fusion reactor are greater than 1.05 for all type of fuels so that tritium self-sufficiency is maintained for DT fusion driver. Values of peak-to-average fission power density ratio, Γ, are in the range of 1.390 and ∼ 1.476 depending on the fuel types in the blanket. Values of neutron leakage out of the blanket for all fuels are quite low due to SiC reflector. The maximum neutron leakage is only ∼ 0.025. Consequently, for all cases, the investigated reactor has high neutronic performance and can produce substantial electricity in situ, fissile fuel and tritium required for (D,T) fusion reaction. © 2002 Elsevier Science Ltd.

W., Department of Physics, Turkmen State University, Ashgabad, TurkmenistanThe heat-pumping scheme based on the 1st order antiferromagnetism-ferromagnetism transition induced in FeRh alloy by one-dimensional tensile stress is proposed. Using the model S-T diagram for this alloy, the heat-pump cycles are drawn up based both on the transition latent heat absorption and emission when the transition is induced isothermally and on the change in alloy's temperature when the transition is induced adiabatically by applying tensile stress. The calculated values of heat coefficient φ for the cycles are ∼30 at ΔT = 5 K and ∼20 at ΔT = 10 K, where ΔT is the difference between the temperature surrounding and that of the heat receiver. These values are achieved using the tensile stress of ∼1·109 Pa.
