Digitalization, while being one of the primary objectives in today's business world, increases its significance with each passing day alongside technological advancements. Recently, there has been a need for tools to determine the levels of digitalization within certain standards and metrics for companies seeking to understand and accelerate their digitalization process, and to determine how these companies should proceed to address their shortcomings. When specifically looking at electricity distribution companies, the technological advancements such as distributed production, storage, and electricity vehicles make the digitalization process not just a choice but a necessity to operate distribution systems reliably and effectively. This study proposes a conceptual model specifically for electricity distribution companies for the first time, by researching digital maturity models developed for other sectors in the literature.

In this study, Al-(Ti:DLC)-pSi/Au Schottky Diode (SD) was manufactured instead of conventional metal-semiconductor (MS) with/without an insulator-layer and then several fundamental electrical characteristics such as ideality-factor (n), barrier-height , series-shunt resistances (Rs, Rsh), concentration of acceptor-atoms (Na), and depletion-layer width (Wd), were derived from the forward-reverse bias current-voltage (I-V), capacitance and conductance as a function of voltage (C/G-V) data using various calculation-methods. Semi logarithmic IF-VF plot shows a linear behavior at lower-voltages and then departed from linearity as a result of the influence of series resistance/Rs and organic-interlayer.

The pure copper oxide thin film was deposited on glass substrates by SILAR method with 30 cycles. To examine the doping effect, Zn-doped films at different doping ratios were prepared under the same conditions as the undoped film. The XRD, SEM and Raman measurements were performed to investigate the morphological structure. Analysis showed increasing aggregation and amorphous structure with doping. The optical parameters were characterized by spectrophotometer measurement and relevant formulas. The band gap energies were determined to increase from 2.50 to 2.79 eV with the increasing Zn rate. The Herve and Vandamme, Moss and Ravindra relations were used to determine the refractive index. The room temperature gas-sensing performance for the undoped and doped samples were reported and the responses for 5 ppm gas were calculated for the 5 ppm 249 %, 800 %, 189 % and 15 % for the CuO, 1Zn:CuO, 3Zn:CuO and 5Zn:CuO, respectively.

The study area is the region where Turkey's most important chrome deposits are located, and extensive serpentine soils are widespread in the region. ın this study, strontium uptake accumulations in the roots and shoots of the Teucrium polium plant growing on serpentine soils in the region were examined.In this context, the soil, roots and shoots of 17 Teucrium polium plants growing on serpentine soils were collected and chemically analyzed for strontium. Chemical analyzes were carried out in ICP-MS (Inductively Coupled Plasma-Mass Spectrometry). On average, strontium values of 15.2 ppm in the soil, 26.4 in the root and 76.3 ppm in the shoots were detected. Strontium enrichment values in the soil, roots and shoots of this plant were determined as 1.8 for ECR, 5.3 for ECS and 2.9 for TLF. This study shows that the Teucrium polium plant accumulates significant amounts of strontium from the soil, both in the root and in the shoots. As a result, this plant can be used as a bioaccumulator plant, especially in the reclamation of strontium-polluted soils and the improvement of such areas.

In the realm of multi-criteria decision making (MCDM), this study introduces the Measurement Relying on the Impacts of an Exponential Curve Function (MIEXCF) as a novel approach for objectively determining criteria weight coefficients. Utilizing exponential curve interactions among criteria, MIEXCF is designed to enrich the MCDM literature. The dataset comprises criterion values extracted from Global Innovation Index (GII) evaluations for 19 G20 members. Results demonstrate the efficacy of MIEXCF in objectively deriving criteria weights for diverse nations. Comparative analyses with other methods (ENTROPY, CRITIC, SD, SVP, LOPCOW, MEREC) further validate MIEXCF's credibility, reliability, and stability. Notably, the simulation analysis indicates MIEXCF's effectiveness in discerning criteria weights and stability across scenarios. In conclusion, MIEXCF stands out as a robust objective criterion weighting technique, offering substantial contributions to exponential functions and the broader MCDM literature.

Aedes albopictus and Ae. aegypti are striped mosquitoes with similar behavioral characteristics. They are known vectors of dangerous arboviruses and are expanding their reach globally. These species have established in specific areas of Türkiye, with Ae. albopictus expanding significantly than Ae. aegypti. While the larval competition of these two mosquito species has been studied, not much is known about their interactions during adulthood. We first investigated the effects of interspecific and intraspecific larval competition on the survival rate into adulthood and the wing length of females and males in containers of different sizes and food level conditions. This research also explored how females of these mosquitoes compete for blood meals in confined environments and its effects on blood feeding rates and female fecundity. Larval competition hinders Ae. aegypti emergence, Ae. albopictus remains resilient across varying resource levels. Notably, both species displayed increased blood feeding rates when housed together, suggesting potential facilitation or competitive avoidance strategies. Interspecific pressure caused a decrease in the number of eggs laid in mixed species cages for Aedes aegypti only. This study highlights the complex competitive dynamics between Ae. albopictus and Ae. aegypti. While larval competition appears to affect Ae. aegypti emergence. Further understanding of adult interactions is crucial for predicting their co-occurrence and effectively managing their populations, especially as Ae. albopictus shows greater adaptability and expansion within Türkiye.

In our study, how the thin metal oxide (aluminium oxide, Al2O3) thin film placed between the metal and the semiconductor on the diode characteristics will affect was investigated. The Al2O3 thin film was suitable for its grown on p-type silicon substrate by atomic layer deposition (ALD) technique. A diode structure with an oxide interlayer was fabricated. To investigate the electrical parameters of the fabricated Schottky diode, measurements of current-voltage (I-V) were carried out at room temperature and in the 5 V voltage range. Using the I-V measurements, diode parameters such as the barrier height (Φb), the ideality factor (n), and the current density (I0) were evaluated using the Thermionic Emission (TE) method. Using the TE method, the approximate values of Φb, n, and Io parameters were calculated as 0.77 eV, 5.43, and 2.43E-09 A respectively. According to calculations, the developed Schottky diode is a rectifier diode and has been determined to have photodiode properties.

Listening to the music affects the brain in ways which might help to promote the human health and arrange various diseases symptoms. Music is a phenomenon that is intertwined at every stage of human life. In the modern era music is formed by the combination of an incredible number of genres, some of which are contemporary, and some come from the past. The music genre represents a collection of musical works that develop according to a certain shape, expression and technique. The music genre of interest varies from person to person in society. Most listeners today do not know what kind of music they listen to. In this study, sound features were extracted from music data and the Keras model was trained using these features. The correct classification rate of a music genre of the trained model was determined as 71.66%. Mel Frequency Cepstral Coefficients (MFCC), Mel Spectrogram, Chroma Vector and Tonnetz methods in the Librosa library were used to extract sound properties from music data. Using the features calculated by the Librosa library, the most listened songs with Shazam in Türkiye were classified in with TensorFlow/Keras. Many methods can be used in classification. It is unclear which method the researchers should prefer. With this study, researchers will know classification with Keras, researchers who do not know about music will know music and know the genre of newly released songs.
聆听音乐对大脑的影响可能有助于促进人类健康和改善各种疾病症状。音乐是一种与人类生活每个阶段都息息相关的现象。在现代，音乐是由数量惊人的流派组合而成的，其中有些是当代的，有些则来自过去。音乐流派是按照一定的形式、表现手法和技巧发展起来的音乐作品的集合。在社会中，每个人感兴趣的音乐体裁各不相同。如今，大多数听众都不知道自己在听什么类型的音乐。在这项研究中，我们从音乐数据中提取了声音特征，并使用这些特征对 Keras 模型进行了训练。经测定，训练模型的音乐流派分类正确率为 71.66%。从音乐数据中提取声音特征时使用了 Librosa 库中的 Mel Frequency Cepstral Coefficients (MFCC)、Mel Spectrogram、Chroma Vector 和 Tonnetz 方法。利用 Librosa 库计算出的特征，TensorFlow/Keras 对土耳其 Shazam 收听率最高的歌曲进行了分类。分类可以使用多种方法。目前还不清楚研究人员应该选择哪种方法。通过这项研究，研究人员将了解 Keras 的分类方法，不了解音乐的研究人员将了解音乐并知道新发布歌曲的类型。
