DSHFS: a new hybrid approach that detects structures with their spatial location from large volume satellite images using CNN, GeoServer and TileCache
Get PDFSatellite images, widely used in recent years and entered the field of remote sensing technology, continuously record image data in databases worldwide. These image data, which are continually obtained, changing, and have a large volume, fall into the big data category. On the other hand, CNN-based techniques, a sub-branch of artificial intelligence, have been widely used to classify and segment image data in recent years. The scope of this study, firstly, it was tried to determine spatial positions and building objects from large-volume satellite images with classical CNN methods. However, classical CNN models could not process the data even in ECW format, one of the most compressed satellite imagery forms. To overcome these problems, a new approach called DSHFS has been proposed. It uses hybrid CNN, GeoServer, and TileCache techniques related to different disciplines to detect structures from large-volume satellite images and their spatial locations. In the proposed DSHFS approach, large-volume satellite imagery is first published in WMS format with GeoServer, which has an open-source strategy. Then, the data are converted into small images containing coordinate information with the TileCache system in size 256 x 256. Finally, the building objects in these images are detected by CNN models. In the proposed DSHFS approach, the actual locations of the detected structures on the earth are calculated using the location information of the image presented as input to the CNN model. In order to examine the performance of the proposed DSHFS approach, satellite imagery covering 12.5 GB in the computer system in ECW format, which corresponds to an area of approximately 17.200 km(2) of Kayseri province, was used. In the proposed DSHFS approach, Faster R-CNN, MobileNet, and YOLO models are used as the CNN model. When the proposed DSHFS approach is examined according to the F1 score, DSHFS Faster R-CNN, MobileNet, and YOLO obtain F1 scores of 0.961, 0.964, and 0.910, respectively. When evaluating the computational efficiency of the proposed approaches, it was found that DSHFS Faster R-CNN, MobileNet, and YOLO took 512.72, 188.20, and 99.35 s, respectively, to identify the structures and their locations in the image. DSHFS YOLO approach detected approximately 2 times faster than MobileNet and approximately 5 times faster than Faster R-CNN. When the proposed DSHFS approach is generally examined, it detects the building objects from the satellite image and their actual positions on the earth in approximately 0.13 s.This work is supported by the Scientific and Technical Research Council of Turkey, within the scope of Career Development Program (3501), Project No: 122E315.

Time-series prediction of organomineral fertilizer moisture using machine learning
Get PDFThis study aims to model and forecast the drying process of three new types of commercial organomineral fertilizers: gold sulfur, 25.5.5, and 5x10 at elevated temperatures. They absorb and release moisture, depending on the conditions. Accurate prediction of drying behaviour is essential. Drying was carried out at temperatures of 70, 75, and 80 degrees C through natural convection. The data are unimodal time series of the moisture rate (MR). MR ). Supervised machine/deep learning techniques such as nonlinear autoregressive (NAR) network, adaptive neural fuzzy inference systems (ANFIS), long short-term memory (LSTM) network, gated recurrent unit (GRU), and hybrid of convolutional neural network (CNN) and recurrent neural network (RNN) are used in addition to wellknown regression-based formulas. The models can predict 30 minutes ahead. An error analysis was performed for performance comparison using the metrics, root mean square error (RMSE), RMSE ), and coefficient of determinant, R 2 . Two types of validation were performed by monitoring error convergence and using prediction curves. The most effective forecasting was obtained at an air temperature of 80 degrees C for all materials with machine learning. While RMSE =0.0030 having R 2 = 0.98843 by the LSTM network for gold sulfur (80 degrees C), ANFIS was the best for 25.5.5 and 5x10 with RMSE =0.0056, R 2 = 0.75585 and RMSE =0.0060, R 2 = 0.81938, respectively, in the MR prediction. GRU was remarkable for both its speed of 13.77 sec and RMSE =0.009. CNN-RNN has a more complex structure but lower performance. The results demonstrate that machine learning techniques are better than regressions. Among them, ANFIS provides the most reliable results. Regressions, including exponential terms, were good at providing a general curve shape but not peaks and drops. In addition, regressions are not good at forecasting

Homojen dağılan ve anlamlı bulunan varyanslarda farkın hangi gruptan kaynaklandığını bulmak için ise Post-Hoc testlerinden LSD Tukey testi ile veriler analiz edilmiştir. Fark, tek yönlü varyans analizi (ANOVA) yöntemi kullanılarak test edilmiştir. İlişkileri test etmek için veri setleri üzerinde Pearson korelasyon testi uygulanmıştır. Araştırma sonucunda elde edilen bulgulara göre, eğitim düzeyinin demokratik lider ve eğitim tipi lider boyutlarına ilişkin sporcu algısı ve antrenörün gerçek davranışı arasında anlamlı bir ilişkisi olduğu bulunmuş, yaş ve profesyonel sporculuk yılına göre sporcu algısının farklılık göstermediği görülmüştür (p<0,05; p<0,001).Today, the concept of leadership, which is an indispensable part of every field of expertise, comes across in every society and in every professional group. Coaches can also have many tasks and powers that fall within the responsibility of a leader for the determined goals. The important question in this obligation is to analyze how these behaviors are perceived by the coaches through the eyes of the athletes in the following position. In this research, it is aimed to examine the perceived leadership characteristics of wrestling coaches working in Adana province and the leadership characteristics that actually exist. For this purpose, the personal information form and the Sports Leadership Scale, developed by Challedurai and Saleh (1980) and adapted in Turkish by Unutmaz ve Gençer (2014), were used to determine the demographic information of the participants and were applied to athletes and coaches. There are five sub-dimensions in the scale consisting of a total of forty items: Education and Information, Autocratic Behavior, Democratic Behavior, Social Supportive and Positive Interpreters. The relationship between the actual leadership behaviors of the coaches and the leadership behaviors perceived by the athletes was evaluated according to these five sub-dimensions and the relationship between them was tried to be determined. In addition, it was examined whether the leadership perceptions of athletes differ according to age, educational status and professional sports year. According to the findings obtained as a result of the research, it was found that the level of education had a significant relationship between the athlete's perception of democratic leadership and educational type leadership dimensions and the actual behavior of the coach, and it was found that the athlete's perception did not differ according to age and professional athletic year (p<0,05; p<0,01)

The research group consists of 460 individuals who live and are married in Şanlıurfa province. Research data were collected using the Marital Life Scale, Self-Disclosure to Spouse Scale, Authenticity Scale and Demographic Information Form. Relational model was used in this research, and findings were obtained using simple regression analysis, SPSS Macro analysis, t test and one-way analysis of variance in the analysis of the collected data. When the results obtained are examined; It is seen that the variables of marital satisfaction and self-disclosure to the spouse differ significantly according to age, working status, duration of marriage and whether or not they have children. Acceptance of external influence, one of the sub-dimensions of the originality variable, varies according to gender and working status. From the results obtained, it is seen that the authentic life sub-dimension differs according to gender, and the self-alienation sub-dimension differs according to working status. While self-disclosure to the spouse and authentic living significantly and positively predict marital satisfaction, accepting external influence and self-alienation predict marital satisfaction significantly and negatively. As a result of the research; It was observed that the sub-dimension of accepting external influence did not have a mediating effect in the relationship between self-disclosure to spouse and marital satisfaction in married individuals. The sub-dimensions of self-alienation and authentic living have a mediating effect between the two variables. It can be said that authenticity is an effective variable in the relationship between self-disclosure to the spouse and marital satisfaction

Study of the pygmy dipole resonance using neutron inelastic scattering at GANIL-SPIRAL2/NFS
Get PDFThe pygmy dipole resonance (PDR) has been the subject of numer-ous studies, both experimental and theoretical. Indeed, the study of the PDR has been and still is of great interest since it allows to constrain the symmetry energy, an important ingredient of the equation of state of nuclear matter that describes the matter within neutron stars. Moreover, the PDR is predicted to play a key role in the r-pro cess via the increase of the neutron capture rate. However, despite numerous experiments dedicated to the study of the PDR, a consistent description is still missing. In this context, we have proposed to study the PDR using a new probe: the neutron inelastic scattering reaction (n,n'-y). An experiment to study the pygmy resonance in 140Ce using the (n,n'-y) reaction has been performed in Septem-ber 2022. This experiment has been made possible thanks to the high-intensity proton beam of the new accelerator SPIRAL2 at GANIL and the NFS (Neutron For Science) facility. The experimental setup was composed of the new generation multi-detectors PARIS, for the detection of-y-rays coming from the de-excitation of the PDR, and MONSTER, for the detection of scattered neutrons. In this article, the experiment motivation and description are presented
COVID again? Health workers' burnout and turnover intentions: possible impacts of coronavirus-induced anxiety and first-level servant leaders
Get PDFPurpose - Building on social exchange and leader-member exchange theories, this paper aims to propose a model of the impact of coronavirus-induced anxiety on health-care professionals' burnout and turnover intention through the mediation role of servant leadership. Design/methodology/approach - This model was examined by adopting partial least square-based structural equation modeling using data collected from 271 health professionals (doctors, nurses, midwives and analysts) from Turkey. Findings - The findings of the research illustrate that coronavirus-induced anxiety is positively associated with burnout and turnover intention. Furthermore, servant leadership mediates the relationship between coronavirus-induced anxiety, burnout and turnover intention. Yet, according to factor loadings, the mediating role of servant leadership is not strong (beta : 0.035 and 0.053, respectively). Research limitations/implications - First, this study targeted the health-care professionals from Turkey. Therefore, this population may not be able to provide general information on the topic. Thus, this study suggests that the subject be addressed in other populations as well. Second, the data were self-reported by the participants. Although common method bias and social desirability bias were not an issue in this study, it should be known that the results are based on the subjective judgments of the participants. Third, this study was limited to investigating the mediating role of servant leadership only. Practical implications - This study gives much beneficial information to both administrators and organizations by mirroring highly stressed workers' inside throughout statistically results. Hence, it is assumed that the findings will help leaders to cope with several difficult situations, especially in crisis moments. As the chaotic circumstances occurred, achieving organizational goals became more and more difficult. To do this, some leaders play critical roles for members like servant leaders by contributing uniquely spiritual dimensions. Social implications - Struggling with the COVID-19 pandemic has aggravated the health-care professionals' existing mental health and has loaded more agitation on them. According to Mozes (2021), suicide cases among nurses have doubled the number of women in the general population. Thus, leaders should do something to lower those ratios. This study points out that servant leaders could break down those unwanted issues by decreasing burnout and turnover intention rates of health workers. Barbuto and Wheeler (2006) highlighted this situation by creating a dimension called The Natural Desire to Serve Others. Originality/value - To the best of the authors' knowledge, to date, this study is the first to examine the mediating role of servant leadership in the effect of coronavirus-induced anxiety on burnout and turnover intention. Furthermore, this research reveals that servant leadership may play a role in avoiding burnout and turnover intention in the health sector
YAĞ YAKMA (YAPMA/ÇEKME) DEYİMİNİN KÜLTÜREL KODLARI ÜZERİNE
Get PDFIn every language there are words whose connection with ancient beliefs has been forgotten. In order to understand, interpret and determine their related connections, folklore and language studies may sometimes be needed in a line extending to mythology. Because there is information formed by the experiences of the past in words and these gain the feature of tradition over time. Therefore, the connection between language and national character and behavior is deep. Words that can be understood through cultural science require ethnological analysis, and their analysis can be done through linguistic analysis. The necessity of understanding these through ethnology also stems from their antiquity. Because it is not always easy to understand and comprehend old elements correctly. This is also valid for the entire vocabulary of Turkish. Various studies have drawn attention to the words that are thought to be related to mythological elements in the Turkish language. Some of these are the statements of g & ouml;z & uuml; kanl & imath;, dar & imath;s & imath; ba & scedil;& imath;m & imath;za, a & gbreve;a & ccedil; kovu & gbreve;u, g & ouml;k ve ay han, y & uuml;z & uuml; g & ouml;mg & ouml;k, g & ouml;k g & ouml;zl & uuml;, g & ouml;k ke & ccedil;inin p & uuml;sk & uuml;ll & uuml; o & gbreve;la & gbreve;& imath; olmak . The number of such exemplary words in the Turkish language may increase even more with the tendencies to be made to native words for this purpose. In the study it is assumed that one of the words that can be explained with Turkish mythology in Turkish is to burn oil. In the study, the connection of the idiom in question with the metaphorical meaning of flattery with the old belief and mythology has been tried to be revealed and the place of oil in the old beliefs of the Turks has been mentioned. We think that the practice of anointing or anointing the t & ouml;s (a kind of figure made for symbolizing generally the member of family who died) within the framework of the cult of ancestors, burning (smoking -smelling) oil in sacrificial offerings to God and commemoration of ancestors is effective in the formation of this idiom and gaining a figurative meaning. When the expression burning oil is evaluated from this point of view, it will be seen that it is an expression directly related to Turkish mythology and the old belief system. Studies of culture, folklore and mythology have shown that Turks used to make t & ouml;s from beech bark, stone, leather or cloth to represent their ancestor spirits within their old beliefs and traditions. The t & ouml;s, which was important for the family, were placed at the corner of the house and fed with oil in their mouths. Because they symbolized the ancestral spirits, which they believed to be immortal, with these representations they made from various objects and called t & ouml;s. Again, on hunting or other special days, various foods, especially oil, and sa & ccedil;& imath; (a kind of gift dropping on holy thing or human) were made for them. These practices for ancestral spirits were to gain their approval, to keep them pleasant, and to lead a life free from dangers and evils under their protection. In particular, oil means that the spirit of the ancestors is considered very important and remembered, as well as the worship of God. It can be said that the use of oil to saturate figurines called t & ouml;s and also called emeget in some Turkish dialects is a kind of blessing. In time, this situation created expressions such as flattering, lubricating, lubricating, meaning to flatter those who have power in order to achieve something, so it seems that a ritual to honor the ancestors' spirits and to reach God for prayers has taken on a figurative meaning. The Turkish sacrificial tradition of oil and the practice of connecting with the sacred of the Turks live in this word as an idiom, but its relation with it has been forgotten. Mythology readings are necessary for a better understanding of culture and language and to determine the origin of words. Increasing studies on cultural textures will make national elements both understandable and consciously alive. The myths that include the beliefs and fears of the first people will also enable the members of the nation to unite around common beliefs and behaviors. It is hoped that the study will make a small contribution to such a need
