  • Matrix Pencil Method and Singular Value Decomposition Application for DOA
           Estimation Using Linear Antenna Array with Multiple Signal Sources

    • Authors: Nilay AYTAŞ; Erkan AFACAN, Nihat İNANÇ
      Abstract: The practice of estimating the direction of the signal emitted from signal sources using linear antenna arrays is used effectively in both military and civilian radar systems. While the number of signal sources was single in the first studies, the systems that estimated the direction angle of the source have now gained the ability to estimate the direction angle of the signals emitted from more than one signal source at the same time with high accuracy, thanks to the deepening researches. In this study, it is aimed to estimate the angle of incidence of noisy signals emitted from multiple signal sources with the least error by using the Matrix Pencil Method and linear antenna array, which is one of the signal subspaceanalysis methods. In addition, the signals are separated from the noise factor by using the Singular Value Decomposition method. Simulations have been carried out in many different scenarios, and it has been shown that the combination of Matrix Pencil Method and Singular Value Decomposition methods can be used for highly accurate results in estimating the direction of multiple signals coming into the antenna array.

  • The Effects of Space Radiation on Small Satellites-General Structure of
           Cubesat and Internet of Space Things

    • Authors: Merve ALTUNAY; Mustafa AKKAŞ, Özge GÖY
      Abstract: Small satellites have started to be produced as a solution to the volume, weight and cost problems of traditional satellites. CubeSat as a small nano satellite whose production is gaining speed today, has contributed to research in space and satellite with the Internet of Things. CubeSat networks that can communicate each other in space are created with the development of the Internet of Things. The performance of satellites is attempted to be maximized with small satellites. Small electronic components of these satellites increase the sensitivity to space radiation. At the same time, the performance of the satellite is affected. More durable materials are being developed to minimize these impacts. In addition,satellites are tested for their durability by irradiating the satellite to be sent with close amounts of space radiation before it is sent into space. Signals that are important in satellite communication are affected by atmospheric conditions. In this context, the effect of the ionosphere which is the layer of the atmosphere on signals is mentioned. A compilation article about CubeSat networks that bring the concept of the Internet of Space Things to the fore, the effects of space radiation on small satellites, the materials that can be used on small satellites to reduce this effect and the radiation tests conducted has been written to address the lack of local resources.

    • Authors: Güllü KIRAT
      Abstract: Ovacık Village is located in Balıkesir province and is 12 km away from Balıkesir Center. The GPS coordinates of Ovacık Village are 39° 43' 51'' North and 27° 47' 37'' East. The stream sediments in the study area consisted of the erosion of magmatic, metamorphic and volcanic rocks and surface waters and eroded rock particles along the stream bed. The relationship between metals in stream sediments has been investigated on the basis of geochemical properties. As, Cd, Cu, Mn, Ni, Pb and Zn element contents of 23 stream sediment samples were taken from different locations from Ovacık village and its surroundings. The minimum, maximum, medyan, median and standard deviation values of these metals in the stream sediments were calculated and it was observed that the mean values were higher than the standard deviation values. The minimum and maximum values (ppm) of the metals studied As: 7.7 - 51.3, Cd: 0.13 - 0.58, Cu: 25.2 - 70.6, Mn: 661 - 1135, Ni: 8.6 - 33.7, Pb: 12.3 - 57.7 and Zn: 59 - 220 According to the Spearman correlation coefficient values, a strong positive correlation was observed between As - Cu, Cd - Pb, Cd - Zn, Cu - Ni and Pb - Zn metal associations (p <0.01). Factor analysis was made with the obtained analysis results and 3 different factor values were created and analyzed. Factor 1: Cd - Pb - Zn association and 37.01% of the total variance; Factor 2: Cu - Mn - Ni association and 24.7% of the total variance; Factor 3: As and total variance was 18.4%, the total variance value was found to be 80.1%. The spatial distributions of the metals were analyzed using the Surfer 9.0 program in the creation of the distribution maps. As and Cu elements at locations 16 and 17; Mn and Ni elements at locations 3, 6 and 7; Cd, Pb and Zn elements have the highest values in locations 3, 12 and 20, they show a similar distribution.

  • Analysis of Factors Affecting Density of Vaccine Centers by Fuzzy ELECTRE
           I Method

    • Authors: Kübra TÜMAY ATEŞ
      Abstract: Nowadays, the increase in vaccinations due to the epidemic increases the density of health centers and shopping centers, which is another place where vaccinations are made, from time to time. The choice of vaccination sites varies from person to person, and this may increase the density of the vaccination sequence. The criteria that cause the increase in density were created by consulting the health personnel, the people who will be vaccinated and those who have had the vaccine, taking into account the conditions and situations that people care about. Alternatively, three different vaccine centers were selected. These centers are designated as hospitals, health centers and shopping centers. Care has been taken to ensure that the designated vaccination centers are places where daily vaccinations are performed. In order to determine the criteria, the opinions of the people were taken by applying a questionnaire. Thus, in this study, which was conducted for the first time, it was investigated which places were more dense with the determined nine criteria and the parameters affecting this density were tried to be analyzed with the Fuzzy ELECTRE I method. Knowing the reasons for these densities and revealing which institutions people frequently prefer for vaccination can prevent problems.

  • Hydrological Drought Analysis for Bolu City with Streamflow Drought Index

    • Authors: Onur ARSLAN
      Abstract: Hydrological drought refers to the decrease in the amount of water found in surface or groundwater resources. Hydrological drought causes serious problems in drinking and irrigation water supply and hydroelectric energy production. In this study, hydrological drought analysis was made for two streams in Bolu city located in the Western Black Sea Region in the north of Turkey. For this purpose, 3, 6 and 12 month flow drought indices were calculated using the Streamflow Drought Index method and the streamflow data of two streamflow monitoring stations. According to the results, extreme and severe droughts were determined for two stream flow stations and it is seen that drought periods varied between 1 and 9 years. The most severe and longest droughts were detected for Bolu stream - Beşdeğirmen station. Mild droughts are much higher than moderate, severe and extreme droughts. It has been observed that the severity and number of drought for Bolu stream - Beşdeğirmen station have increased in recent years. In order to reduce the effects of hydrological drought, hydrological drought should be monitored continuously and necessary precautions should be taken regarding the management of water resources. People should be informed about water consumption and so waste should be prevented. In terms of irrigation water, drip irrigation method should be used instead of flood irrigation or sprinkler irrigation methods. For this aim, farmers should be made aware of this issue. Alternative renewable energy sources or other energy sources should be used for reductions in hydroelectric energy production.

  • Multi-Scale Modeling of Graphene/Polymer Nanocomposites-Molecular
           Interfacial Interactions

    • Authors: Umut CALİSKAN; Saadettin KAHRAMAN, Talha KOÇYİĞİT
      Abstract: This paper presents a multi-scale modeling approach involving interfacial interactions to predict the elastic properties and mechanical behavior of single-layer graphene-reinforced nanocomposites under tension load. A multi-scale model was developed using the finite element method of the tripartite structure consisting of graphene in epoxy, the interfacial region and their Van Der Walls interactions. The effect of graphene chirality was investigated by proposing a methodology of graphene-Van Der Walls interactions-polymer with determined geometric dimensions. Parametric modeling was performed to model the interactions between Van Der Walls, graphene and interface material atoms using the finiteelement method with molecular mechanics approach. Numerical analysis of graphene nanoparticles by embedding them in an epoxy with their real dimensions is not an appropriate task today. In particular, it is not possible to analyze these real graphene nanoparticles as multiple by randomly dispersing them in the epoxy polymer. Therefore, in this research, a model was developed to overcome this problem and to investigate the effect of molecular interactions on loads in different axes. The results show that graphene nanocomposites in armchair geometry give higher stress values and behave more rigidly. As the volume ratio increases, the mechanical performances increase. It is seen that the graphene directionis much stronger than the thickness direction. It is clear that the volume ratio effect in the thickness direction has a slight effect on the tensile behavior.

  • Methane, Diesel Fuel, Electrical Energy, CO2 Emissions and Economical
           Equavialent from Animal Manure of Tokat, Turkey

    • Authors: Kazım KUMAŞ; Ali Özhan AKYÜZ
      Abstract: The animal husbandry sector is becoming a rapidly developing sector in Turkey and more waste is emerging in animal husbandry enterprises. It is necessary to dispose of these wastes that have a negative environmental impact. In search of new energy sources, it is becoming increasingly important to dispose of organic waste and use it in biogas production as an alternative energy source. Expanding the production of biogas will be very effective both in reducing external dependence on energy and in reducing the carbon emissions that cause global warming. There are various studies in the literature on biogas potential calculations in Tokat province. In this study, animal species were given in detail, and district-based calculations were made and total biogas production potential was determined for Tokat, Turkey by taking into account different animal types according to 2020 Turkish Statistical Institute (TUIK) data. Different energy equivalent transformations that can be obtained depending on the biogas potential have been studied. The amount of benefits in TL that can be obtained for conversions has been determined. According to the total number of animals, the total amount of waste in the province was determined to be 249596 tons per year. The annual amount of biogas that can be obtained from waste is 49.92 x 106 m3 . It has been determined that this amount can be converted into 1133 x103 GJ thermal energy, 234.62 GWh electrical energy, and 32.95 x 106 liters. It has been calculated that 85636252 TL will be used for the conversion of biogas to electrical energy and 215822500 TL will be used for the conversion of diesel fuel.

           And Their Xenophobia Towards Refugees Of The Midwifery Students

    • Authors: Ayşenur KAHRAMAN; Ayşe ÇATALOLUK, Özgür ALPARSLAN
      Abstract: The research was conducted to determine the relationship between the xenophobic attitudes of midwifery students towards refugees and their conscientiousness. The descriptive and cross-sectional study was conducted with students studying in the midwifery department of a health sciences faculty between April 15 and May 15, 2021. The population of the study consisted of midwifery students (N=368), and the sample consisted of 218 students who voluntarily agreed to participate in the research. “Personal Information Form”, “Conscious Intelligence Scale” and “Xenophobia Scale” were used as data collection tools. According to the xenophobia scale total scores of the students participating in the study,it was determined that xenophobia was below the moderate level and the conscientious intelligence scores were quite high. A statistically significant difference was found between the students' grades and the total scores of the xenophobia scale. As a result of the correlation analysis performed to determine the relationship between the scales, no significant relationship was found between the total scores obtained from the scales. Positive and weak (r=.144, p=0.034) between the total score of the Xenophobia scale and the ethical values sub-dimension of the Conscientious Intelligence Scale, and weak (r=-.191,) between the total score of the Xenophobia scale and the compassion sub-dimension of the Conscientious Intelligence Scale. p=0.005) relationship was determined. In the study, it was determined that midwifery students' fear of refugees was below the medium level and their conscientious intelligence scores were quite high. This research will fill the gap in the field and will provide a new perspective on the approach and communication to refugees in the provision of health services.

           Government Performance during the Pandemic on Their Trust in COVID-19
           Vaccine

    • Authors: Fuat YALMAN; Yalçın KARAGÖZ
      Abstract: The main purpose of this research is to determine the impact of people's preventive health behavior and trust in government performance during the pandemic on their trust in COVID-19 vaccine. The population of the research consisted of middle and advanced age group individuals who received service from pharmacies in the city center of Karabük. In the study, convenience sampling method was preferred due to the difficulty of reaching the participants during the COVID-19 pandemic process and 400 questionnaires were returned at the end of the data collection process. SPSS and AMOS package programs were used in the analysis of the data. Confirmatory factor analysis and path analysis techniques were applied to the data. The findings obtained by confirmatory factor analysis and path analysis showed that the construct validity of the model was ensured. According to the path analysis results, it was determined that the participants' protective health behavior (β=0.339; p<0.05) and their confidence in government performance (β=0.265; p<0.05) affected their confidence in the COVID-19 vaccine statistically and positively. During the pandemic, their COVID-19 vaccine acceptance and COVID-19 vaccine confidence increase as people engage in more and more accurate preventive health behavior and have confidence in government performance.

  • An Optimization Focused Machine Learning Approach in Analysing Arts
           Participative Behavior with Fine Arts Education Considerations

    • Authors: Özerk YAVUZ
      Abstract: Fine arts education constitutes an important value for the development of nations, countries and geographies. In literature it is seen that societies and nations that give importance to fine arts, other art forms with respective education programs and agendas seem to be more developed in the fierce competitive environments. It is a known fact that art forms enhance the creativity of individuals as well as developing questioning skills and empathy. Therefore cultural plans, programs and agendas handled in the cultural ministry or similar levels should always be considered as a chance for investments made for the development of individuals and society at large. Therefore enough budgets for cultural programs should be maintained. Academic and pre-university degree art programs should be designed and formed in response to the changes and developments in the contemporary art world. Graduates should also be prepared in these programs to the career paths that they want to follow in these areas. Understanding the domain of art marketing as well as implementing marketing strategies, plans, programs in every level in this context can be helpful in enlarging the arts market which means creating more jobs and employment opportunities for more actors and actresses. Qualification of these talents should also be supported with academical or nonacademical artistic education forms. In this study theatres located in Istanbul Municipality and theatre participation behavior has been analyzed with recent machine learning trends and approaches available in data mining literature with the aim of enhancing exploratory and confirmatory understanding in such domains as theater, entertainment and art marketing with the aim of providing some insights and ideas to the arts community, leaders and society at large.

  • A Classification and Clustering Approach Using Data Mining Techniques in
           Analysing Gastrointestinal Tract

    • Authors: Özerk YAVUZ
      Abstract: In having a healthy life, right nutrition with a life style balanced with exercise constitutes and important value. This is mainly important for bodily functions that are provided by organs and systems of the body which is also valid for our digestion and excretion systems. In having a healthy life right nutrition with a life style balanced with exercise constitutes and important value. Digestion is one of the main functions of human metabolism that starts in mouth with mechanical and chemical reactions and ends with the expellsion of digestive residues from the anus, following the large intestine. Many hormones and enzymes have influence in the digestion of carbonhydrates, proteins and fats in the metabolism. With the key and luck structures that enzymes have and with the hormonal homeostasis that the metabolism have processing of different monomer and polimer structures are being handles. After the absorbation of digested food contents in duodenum and small intestine. Digestive residues are expelled from the anus, following the large intestine. If there is a malfunction in some part of the digestive system or characteristics of the food taken some digestive and excretion problems may occur. Some of these most known problems are constipation and hemorrhoids. In this phenemonelogical, single case study, some of the factors that have influence in defecation with development of constipation and hemorrhoids investigated with the aim of enhancing exploratory and confirmatory understanding for medical specialists and society at large.

  • Opposite Based Crow Search Algorithm for Solving Optimization Problems

    • Authors: Burhanettin DURMUŞ
      Abstract: This article proposes an opposite based learning (OBL) enhanced crow search algorithm (CSA) version for solving optimization problems. The proposed method, named the opposite based CSA (ObCSA), starts searching with individuals with higher fitness in the initial phase of the evolutionary process. In this way, it is aimed to improve the convergence performance of the basic CSA. To validate the proposed method, a set of benchmark test suit of different of features is chosen. Its convergence characteristic and statistical results are compared with the basic CSA. The results obtained show that the proposed method improves the convergence performance of the basic CSA. And the statistical results indicate that it manages to reach the near optimal solution and increases the quality of the solution.

  • Machine Learning Based Short Term Load Estimation in Commercial Buildings

    • Authors: Mustafa Yasin ERTEN; Nihat İNANÇ
      Abstract: Nowadays, there are many problems with the electricity system, such as increasing consumption, short-time overload during the intra-day, environmental problems caused by fossil fuel, and foreign-source dependency. Therefore, it is necessary to meet these increasing energy needs, minimize environmental impacts, and develop cost optimization solutions. In order to meet these requirements, it is necessary for the network to have a more dynamic structure and to have real-time monitoring and control systems. Furthermore, to develop the aforementioned system, it is necessary to estimate the load of the users in the system. Therefore, the developed artificial neural network-based load estimation algorithm is capable of high accuracy load estimates, and high precision data were obtained for use in the demand side management system

  • The Effect Of The Covid-19 Pandemic On Health Services

    • Authors: Altuğ ÇAĞATAY; Ümit ARSLAN, Seda YILMAZ
      Abstract: In this study, it is aimed to compare the health statistics of OECD countries in terms of Covid-19 and general health statistics. Quantitative screening method was used in the study and health statistics of OECD 2020, 2021, World Health Organization Covid-19 statistics and Ministry of Health 2019 health statistics were used. According to the number of Covid-19 cases reported among OECD countries, the high death rate is in Hungary with 3.083 per hundred thousand, Italy with 2.610 per hundred thousand, Colombia with 2,533 per hundred thousand, Chile with 2.170 per hundred thousand and 1.920 per hundred thousand. It is in Greece. The lowest death rates are in Norway with 378 per hundred thousand, Denmark (558), Israel (609), Finland (706), Netherlands (711) and Turkey with 873 per hundred thousand. The lowest deaths by population occurred in South Korea (‰ 0.08), Australia (‰ 0.08) and Japan (‰ 0.15). Turkey is among the countries where the number of deaths from Covid-19 is low (‰ 0.94) according to the population. The countries with the highest rate of intensive care beds are Czechia, Turkey and Estonia. The average length of stay in hospital was highest in South Korea (18 days), Japan (16 days), and Hungary (9.6 days). The minimum length of stay in hospital is in Turkey (4.2 days), Mexico (4.4 days) and the Netherlands (5.2 days). In general, when we look at the health statistics of our country, we can say that it is in better condition than other OECD countries. However, the number of health personnel needs to be increased. When compared with the Covid-19 data (death rates, bed occupancy rates, etc.), it is seen that our country is successful in the fight against Covid19. It is thought that this result depends on the strength of the health infrastructure. With the increase in vaccination, it is expected that deaths due to Covid-19 will decrease even more all over the world.

  • Learning Based Super Resolution Application for Hyperspectral Images

    • Authors: Hüseyin AYDİLEK; Nihat İNANÇ
      Abstract: Due to its spectral properties, hyperspectral imaging is superior to other types of imaging tools in identifying, distinguishing and classifying objects. Hyperspectral imaging instruments can detect light reflected from certain wavelengths between infrared and ultraviolet, apart from the wavelength that the human eye can distinguish on the electromagnetic spectrum. While this feature provides detailed information about the spectral feature of the object under investigation, it causes its spatial resolution to be low due to the technical overlap between spatial resolution and spectral resolution. Today, applications of hyperspectral images are increasing in important fields such as agriculture, mining, medicine and pharmacy, especially for military purposes. In order for applications to produce more precise results, high spatial resolution is required, as well as high spectral information. Hardware solving of low spatial resolution problem is a difficult and costly method. Therefore, software solution is an interesting area in the field of image processing. In this thesis, a hybrid solution method based on deep learning and sparse representation is proposed to increase the low spatial resolution of hyperspectral images. The method obtains a super-resolution image from a single hyperspectral image with a low spatial image with a deep convolutional mesh. Later, the super-resolution image obtained and the original low-spatial-resolution hyperspectral image are fused with the dictionary learning method, resulting in a new super-resolution image with high spectral and spatial resolutions. The application results show that our method achieves successful results compared to many super resolution applications in the literature.

  • Drawing the Building TAKS Boundaries with the Help of the Sine Theorem of
           Planned Type Zoning Building Regulations

    • Authors: Selim TAŞKAYA
      Abstract: Zoning plans are the design work required for the correct use of space in terms of urbanization. While creating zoning plans, zoning islands are created together with various planning methods. Reconstruction islands are also named as having legends such as residence, subject + commercial, commercial, social areas, religious facility areas called places of worship, green areas. The important part is how the construction permit is given to the parcels that will coincide within these islands. This process is the zoning diameter. Zoning diameters are the drawings made on the ground according to different methods. In our study of how to give zoning diameters to different types of zoning islands, it was aimed to provide appropriate angle distances inside perpendicular or parallel by adding the lengths of the parcels to each other, which we call the sine theorem. It was examined how the zoning island would be given a diameter in terms of length according to the precedent and the amount of height processed in the plan.
