Investigation of Variables That Affect the Urban Water Consumption Over Some Districts of Konya City 科尼亚市部分地区城市用水量影响因素调查
Omıdullah Zeın Ebad, V. Yılmaz
As it is known, the importance and consumption of water are increasing day by day due to industrial growth, population growth, advancement of technology and increasing living standards. Because of the limited water resources, the design, planning, forecasting of water transmission and distribution systems should be made more carefully and the water resources should be used more efficiently. In this context, the importance of the factors affecting water demand is increasing day by day. Population, economic cycles, education, technology, climatic conditions, price, and many other factors have their effects on water consumption. By designating these effects in a healthy and reliable way, it is possible to design systems that are more reliable and to use water resources more efficiently. In the present study, by using water consumption data of 4 different neighborhoods of the central districts of Konya with different characteristics, the effects of meteorological variables on water consumption according to the characteristics of neighborhoods were investigated by using Multiple Regression Analysis.
众所周知,由于工业的发展、人口的增长、科技的进步和生活水平的提高,水的重要性和消耗量日益增加。由于水资源的有限性,需要对输配水系统的设计、规划和预测进行更细致的研究,提高水资源的利用效率。在这种情况下,影响用水需求的因素的重要性日益增加。人口、经济周期、教育、技术、气候条件、价格和许多其他因素都会对用水量产生影响。通过以健康可靠的方式指定这些影响,就有可能设计出更可靠的系统,并更有效地利用水资源。本研究利用科尼亚中心区4个不同特征街区的用水量数据,根据不同街区的特点,采用多元回归分析方法,考察气象变量对用水量的影响。

THE SIMULATION OF MATHAMETICAL MODEL OF OUTER ROTOR BLDC MOTOR 外转子无刷直流电机数学模型的仿真
M. Kelek, I. Çelik, U. Fidan, Y. Oğuz
In this study, mathematical modeling of outer rotor brushless direct current motor (BLCD) is performed. Brushless direct current motor is highly preferred in industrial applications when compared the other motor types with considering advantages and disadvantages. Producing higher torque with smaller dimensions, being easily controllable and developing high efficiency electronic materials can be given such an example of these advantages. In this study, an outer rotor brushless DC motor which was used in the laboratory is modeled. This motor hasn’t currently information parameters. For this reason, first of all, the metric measurements, phase winding orders are obtained for the motor parameters. With the motor parameters that we have, the motor was created and analyzed in Maxwell program environment. And then the parameters (torque constant, back EMF constant, phase resistance, etc.) were obtained required for the simulation. Mathematical model was completed with the obtained parameters in Matlab / Simulink environment. So, Torque characteristics, motor speed and trapezoidal back-EMF were determined. The motor currents matched with the Maxwell and Matlab / Simulink programs. So the accuracy of the simulation modeling has been confirmed.
本文对外转子无刷直流电机(BLCD)进行了数学建模。与其他类型的电机相比,考虑到优点和缺点,无刷直流电机在工业应用中是高度首选的。以更小的尺寸产生更高的扭矩,易于控制和开发高效率的电子材料可以给出这些优点的例子。本文对实验室使用的外转子无刷直流电动机进行了建模。这台电机目前没有信息参数。为此,首先得到了电机参数的公制测量值、相位绕组阶数。利用已有的电机参数,在Maxwell程序环境中对电机进行了创建和分析。然后得到仿真所需的参数(转矩常数、反电动势常数、相阻等)。利用得到的参数在Matlab / Simulink环境下建立数学模型。因此,确定了转矩特性、电机转速和梯形反电动势。电机电流与Maxwell和Matlab / Simulink程序匹配。从而验证了仿真建模的准确性。

Colorization of 1-D photonic crystals with Rare-earth element doping 稀土元素掺杂一维光子晶体的着色研究
O. Keskin, N. Funda Ak Azem, I. Birlik, R. Dalmış
Nowadays, nature-inspired structural colorization takes increasing attention due to its exceptional optical properties. One-dimensional (1-D) photonic crystals are new kind of optical materials which can be used to obtain structural colorization. In recent years many studies carried out about 1-D photonic crystals because of its simplicity and cost effectiveness. In this study, CuO/TiO2 multilayer thin films were prepared by the sol-gel spin coating technique on the boron silicate substrate. To understand the effect of rare-earth element doping on structural colorization, Cerium and Europium ions doped CuO layers were prepared with different dopant concentrations. Structural and morphological properties of 1-D photonic crystals were investigated by Xray diffraction (XRD), Scanning electron microscopy (SEM) and optical microscopy. Obtained results show that CuO/TiO2 multilayer thin films with different Cerium and Europium concentrations were successfully prepared. Additionally, red and green colorization was achieved with different type and concentrations of dopant elements and more vivid colors were obtained as a result of the increment in dopant concentration.

Konsantrasyonlu Fotovoltaik Termal Bir Sistemde Soğutucu Akışkan Tipi ve Kanal Geometrisinin Elektriksel Verim ve Isıtma Kapasitesine Etkisi
Burak Kurşun, Korhan Ökten
Özet – Günümüzde gelişen teknolojiyle birlikte artan sera gazı emisyonları ve küresel ısınma problemleri yenilenebilir enerji kaynaklarının kullanımını önemli ölçüde artırmıştır. Yenilenebilir enerji kaynakları güneş enerjisi, rüzgar enerjisi, jeotermal enerji, hidrolik enerji, biyokütle enerjisi ve hidrojen enerjisi olarak sınıflandırılabilir. Güneş enerjisi büyük ölçüde ısıl radyasyon yayması, temiz ve sınırsız olması bakımından yenilenebilir enerji kaynakları arasında çok önemli bir yere sahiptir. Konsantrasyonlu fotovoltaik termal sistemler (KFVT) güneş enerjisinden elektrik ve ısıl enerji elde edilmesinde kullanılan cihazlardan bir tanesidir. KFVT sistem ile güneş enerjisi direkt olarak elektriğe çevrilmekte ve bu sırada fotovoltaik modül üzerinde oluşan atık ısıdan akışkanların ısıtılmasında faydalanılmaktadır. Bu çalışmada bir KFVT sistemde farklı akışkan kullanılması ve kanal geometrisinin değiştirilmesi durumunda oluşan elektrik üretimi ve ısı kapasitesi termodinamik olarak incelenmiştir. KFVT sistem dikdörtgen bir akışkan kanalına sahip olup dikdörtgen kanalın en/boy oranı değiştirilerek elde edilen modül sıcaklıkları, elektrik üretimi ve akışkan sıcaklıkları birbiri ile karşılaştırılmıştır. Isı transfer akışkanı olarak organik soğutucular kullanılmıştır. Akışkanların değişken termofiziksel özellikleri sistemin elektriksel verimini ve atık ısı miktarını farklı oranlarda etkilemiştir. Termodinamik analizler sonucu elde edilen bulgular elektrik üretimini, modül sıcaklılarını, akışkan çıkış sıcaklıklarını ve sistem verimini içeren grafikler halinde sunulmuştur.

Abstract – – In this paper, driving point impedance functions,     1 2 ( ) .... Z s A c s b c s b       , which are frequently used in electrical engineering, have been considered for boundary analysis of the Schwarz lemma. Accordingly, considering the 1 s , 2 s , ..., n s points in the right half plane which are different than s b  , Schwarz lemma has been obtained for positive real functions. In addition, a result of the Rogosinski’s lemma has been used to prove the new inequalities and the derivative of the driving point impedance function has been evaluated from below by considering Taylor expansion coefficients 1 c and 2 c . For all presented inequalities, sharpness analysis has been carried out and extremal functions corresponding to different driving point impedance functions have been obtained. It is possible to say that simple circuits can be synthesized using the obtained transfer functions.

The study area covers Kaz Mountain and its surroundings which is located in the north of Güre, Çamlıbel and Arıtaşı Neighborhoods of Edremit District of Balıkesir Province. The Kazdağ Massif which is estimated to be of Paleozoic primitive age starts with the Fındıklı formation in the lower part. This formation is composed of hornblende gneiss, biotite-hornblende gneiss, epidote-hornblende gneiss, epidote-biotite gneiss, garnet-biotite gneiss, garnet-hornblende gneiss, disten-garnet-mica schist and disten-garnet-biotite schist which show alternation with crystallized limestones (Altınoluk marble member). In the upper part of the Fındıklı formation, there are crystallized limestones (Babadağ marble member). Tozlu formation which is tectonically overlain Fındıklı formation consists of amphibolite – amphibole schist (amphibolite member), metadunite – metaproxenite – metaproxenhornblendite serpentinite (metaophiolite member) and crystallized limestones (marble member) with lateral-vertical transition with each other. Sarıkız formation is observed with an unconformity on Tozlu formation. Sarıkız formation starts with the thin gneiss level in the lower part, and upwards, higher up pass into thick crystallized limestones with calcschist interlevels. In the upper part Sütüven formation which is observed tectonically is composed of mica gneiss sillimanite-biotite gneiss hornblende-biotite gneiss including granitic gneiss (granitic gneiss member) amphibolite marble bands and lenses. The anatexis ve migmatite is sometimes observed in Sütüven formation. The mineral assemblage which consist of hornblende (tschermakite, edenite and barroisite) + plagioclase (albite-oligoclaseandesine) + quartz ± orthoclase + biotite (brown, green) + garnet (prop-almandine-grossular) ± epidote ± zoisite / clinozoisite ± chlorite (ripidolite-picnochlorite, penninite-clinochlore) ± kyanite ± staurolite + muscovite ± calcite ± sillimanite ± microcline + tourmaline (green, brown) + sphene ± rutile ± apatite are observed in amphibole gneisses and biotite gneisses which constitute the dominant lithology of Fındıklı formation.

The Kazdağ Massif which is estimated to be of Paleozoic primitive age starts with the Fındıklı formation in the lower part. This formation is composed of hornblende gneiss, biotite-hornblende gneiss, epidote-hornblende gneiss, epidote-biotite gneiss, garnet-biotite gneiss, garnet-hornblende gneiss, disten-garnet-mica schist and disten-garnet-biotite schist which show alternation with crystallized limestones (Altınoluk marble member). In the upper part of the Fındıklı formation, there are crystallized limestones (Babadağ marble member). Tozlu formation which is tectonically overlain Fındıklı formation consists of amphibolite – amphibole schist (amphibolite member), metadunite – metaproxenite – metaproxenhornblendite serpentinite (metaophiolite member) and crystallized limestones (marble member) with lateral-vertical transition with each other. Sarıkız formation is observed with an unconformity on Tozlu formation. Sarıkız formation starts with the thin gneiss level in the lower part, and upwards, higher up pass into thick crystallized limestones with calcschist interlevels. In the upper part Sütüven formation which is observed tectonically is composed of mica gneiss sillimanite-biotite gneiss hornblende-biotite gneiss including granitic gneiss (granitic gneiss member) amphibolite marble bands and lenses. The anatexis ve migmatite is sometimes observed in Sütüven formation.
