Approach for siting a support facility for transporting supplies in emergency cases in the Republic of Bulgaria

In this paper, the author determines the most suitable transportation location for intervention in a large scale disaster in the Republic of Bulgaria, by means of the Weber Problem and the Weiszfeld method. The objective is to minimise the cost of transporting emergency supplies across the country by locating a support facility, and thus reaching the area of event at the lowest possible cost. A brief description of the Weiszfeld method is provided in the paper. Further, using recent population data of both provinces and municipalities, the method is applied respectively to obtain the results. They were compared in terms of spatial correspondence and the final facility location was fixed. Erecting the supply site is recommended to help decrease the losses.No sponso

Identification and characterization of network paths

Many transportation analyses involve fusing multiple sources of data to build a better representation of how a transportation system can be or is used. However, the integration of multiple data sources, each of which may entail a range of uncertainties, can make inferences of system characteristics a challenging problem. In this context, a better understanding of how data on transportation activities, network topology, and geospatial context are related to one another is needed. To address these issues, this dissertation investigates methods for: 1) associating location-based observations of movement with network topology and other measurements of activity, 2) modeling the relationship between geographically referenced observations of transportation activities and other geographic features, and 3) assessing the spatial similarity among network paths. New methodologies for addressing these themes are proposed, and applicability of these methods to a real-world transportation analysis problem is demonstrated through an implementation in a commercial geographic information system (GIS)

An Investigation on “Property Right” of the Trabzon Ayasofya Mosque

Mülkiyeti mazbut Fatih Sultan Mehmet Vakfı’na yönetim ve temsili 5737 sayılı Vakıflar Kanunu ile Vakıflar Genel Müdürlüğü’ne (VGM) ait Trabzon Merkez Fatih Mahallesi’nde “çeşmesi olan bahçeli kargir cami” vasıflı, 6.951,75 m2 miktarlı vakıf taşınmaz, vakıf taşınmaz mallar kütüklerinde mazbut hayrat olarak tescillidir. Bu vakıf taşınmaz aynı zamanda 2863 sayılı Kültür ve Tabiat Varlıklarını Koruma Kanunu uyarınca “korunması gerekli kültür ve tabiat varlığı” olarak tescilli olup 1.derece arkeolojik sit alanında bulunmaktadır. Taşınmazı VII. Osmanlı Padişahı Fatih Sultan Mehmet’in Trabzon’u 1461 yılında fethetmesi ile kendi kurduğu vakfına alarak camiye dönüştürüp vakfettiği bilinmektedir. Uzun süre VGM rızası dışında müze olarak kullanılan bu taşınmazın vakıf hukukuna uygun olarak tekrar cami vasfında kullanımı tartışılmıştır. Bu çalışma kapsamında Cumhuriyet’ten sonra taşınmazın mülkiyet hakkı kavramı çerçevesindeki hukukî durumu ülkemizin de tanıdığı uluslararası beyanname, sözleşme ve protokoller ile Anayasa, Medeni Kanun, Vakıflar Kanunu, Kadastro Kanunu, Kültür ve Tabiat Varlıklarını Koruma Kanunu ve Gayrimenkul Kiraları Hakkında Kanun çerçevesinde irdelenerek, taşınmazın konu olduğu idarî kararlar ve yargı kararları da özetlenerek taşınmaz özelinde değerlendirmeler yapılacaktır.Ayasofya Mosque as the property of The Foundation of Fatih Sultan Mehmet is administered and represented by General Directorate of Foundations (VGM) in Turkey, according to the Foundations Law numbered 5737. It is 6.951,75 m2 at Fatih District in Trabzon and registered as mazbut waqf on title deed “masonry mosque garden with fountain”. In addition, it is registered on title deed “cultural and natural property to be protected” and is in first-degree archaeological protected area according to Protection of Cultural and Natural Heritages Law numbered 2863. It is known that VIIth Ottoman Sultan, Fatih Sultan Mehmet conquered Trabzon in 1461. After the conquest, Fatih Sultan Mehmet converted Ayasofya into a mosque by including its own foundation. In a long time Ayasofya was used as a museum without permission of General Directorate of Foundations and usage of Ayasofya as a mosque has been discussed instead of a museum because of its status in accordance with the law of foundations. In this study, after establishment of Turkish Republic legal status of Ayasofya Mosque in terms of the concept of property rights will be investigated by examining the Universal Declaration of Human Rights, European Convention on Human Rights, The Constitution, Civil Law, Foundations Law, Cadastre Law, Protection of Cultural and Natural Heritages Law, Letting Law. Administrative decisions and adjudications will be summarized

Iterative methodology on locating a cement plant

In this study, a cement plant location was determined by considering essential parameters such as the locations of resources and their importance in the manufacturing process. A crucial mathematical problem, named Weber problem, reinforced the decision of the method of allocating the factory. Additionally, not only the limitations of the cement production but also the importance weights of goods used in the manufacturing were taken into account in the iterative methodology in order to answer the engineering question via the mathematical problem. As a result, by optimizing the case through the iterations introduced in the paper, the location of the cement plant was set. Hence several losses such as extra travel distances and time wasting in transportation were minimized.No sponso

Havalimanlarında kalkış öncesi, acil durumlarda, yardım alınabilecek en uygun lokasyonun Weber problemine uyarlanarak belirlenmesi

Türkiye’de son yıllarda sivil havacılık hızlı bir şekilde gelişmiştir ve bu ivme artarak devam etmektedir. Tüm dünyada ve ülkemizde hızla büyüyen sivil havacılık sektörü ve işletmeciliği hemen hemen herkesin kullanımına elverişli olan bir alandır. Sivil havacılığın her geçen gün beraberinde getirdiği sorunlara yönelik çözümler oluşturulması adına birçok akademik araştırma yapılmıştır ve halen yapılmaktadır. Çoğu kez karşılaşılan sorunlardan bir tanesi de acil ve beklenmedik durumlarda bakım ve yedek parça hizmetlerinin başka bir havalimanından tedarik edilmesinin gereğidir. Gerekli olan bakım, onarım veya yedek parça hizmeti çok hızlı bir şekilde tedarik edilmelidir ki havayolu şirketinin zamansal ve dolayısıyla parasal kaybı da en aza inmelidir. Bu makale çalışmasında Türkiye’nin sivil havalimanlarından sağlanan veriler ile birlikte, bahse konu sorunun ülke çözüme kavuşturulması konusunda en kullanılabilir havalimanının sınırları içerisinde tespiti, Weber problemine uyarlanıp Weizsfeld yöntemi kullanılarak çözümlenmiştir. Bu çalışmanın sonucunda, yurtiçinde bu önemli soruna karşılık hizmet verebilecek en uygun lokasyona sahip havalimanına dikkat çekilmiştir. Elde edilen bulgular doğrultusunda, kalkış öncesi uçuş emniyetinin sağlanması, beklenmedik durumların oluşma riski göz önünde bulundurulmalıdır. Bu risk payının gerçekleşmesi durumunda ek maliyetlerin oluşması, zaman kaybı, gecikmelerden kaynaklanan müşteri memnuniyetinin azalması gibi zararların en alt seviyede tutulması için bu makaledeki çalışmanın sonuçları yol gösterici olacaktır. Analizler sonucu belirlenen havalimanının Türkiye çapına servis sağlaması ve acil durumlarda talep edileni karşılaması açısından en kullanılabilir havalimanı olduğu değerlendirilmektedir.In recent years, civil aviation in Turkey has developed rapidly and this developing rate continues. Civil aviation sector and its management which is still advancing in our country and throughout the world are commonly available to be utilized by almost all people. Many academic research has been completed and many are being carried out in order to solve the problems which are brought by the rapid growth of civil aviation.

As a result, in terms of location, the best fit domestic airport which can serve to solve such an important problem is pointed out. In accordance with the findings, in order to provide a safe flight and take the risk of unexpected cases prior to the flight into consideration, this study will be instructive to decrease the losses such as time wasting, decrease of customer satisfaction rates, additional costs once the risk mentioned occurs. The airport, which is the most applicable in terms of location, to provide service to the other airports throughout Turkey is determined according to the analysis.No sponso

Traffic data based ideal airport suggestions providing regional service in disasters

Bu çalışma, önceki benzer çalışmalardan üç ana yönden ayrılmaktadır. Birincisi, yöntem olarak diğerlerinden ayrılarak ülke çapında sadece tek bir lokasyondaki havalimanı tesisi değil kümeleme yöntemi uygulanarak bölgesel hizmet verebilecek en uygun tesisler tespit edilmiştir. İkincisi, önceki çalışmalarda İstanbul Havalimanı henüz hizmete girmediğinden dolayı değerlendirmeye alınmamışken, bu çalışmada optimizasyon hesaplarına dahil edilmiştir. Üçüncüsü, yeni durumun önceki çalışmalara nazaran daha güncel verilerle ve daha güncel bir optimizasyon yöntemi olan ağaç tohum algoritması kullanılarak optimum çözümler üretilmiştir. Trafik verileri, trafiğe dayalı ağırlık katsayıları ve ulaşım mesafelerinin elde edildiği konum verilerine dayanarak yapılan analizler sonucunda, toplam on altı havalimanı kendi bölgelerine, özellikle herhangi bir felaket sırasında veya sonrasındaki acil durumlarda, servis sağlayabilecek ideal havalimanları bu çalışmada ortaya çıkarılarak tavsiye edilmiştir. Bu araştırmanın önerileri doğrultusunda, herhangi bir acil durumda gerekli olan ve havayolu ile sağlanabilecek hizmetler sayesinde zaman ve gider kaybının azaltılması gibi amaçlar gözetilirken daha da önemlisi can kaybının en az düzeye indirilmesi konusunda ilerleme kaydedilmesi beklenmektedir.This study differs from previous similar studies in three main directions. Firstly, the location of the most suitable facilities that can provide regional service were determined by applying clustering method. Thus, not only one airport facility in a single location serving across the country was determined, which separates this research from the others. Secondly, in the previous studies, Istanbul Airport was not taken into account because it has not been put into service. Therefore, this study takes that particular airport into consideration. Thirdly, optimum solutions for such new situation were produced with more up-to-date data and using a modern optimization method, the tree seed algorithm. As a result of the analyzes made based on traffic data, traffic-based weight coefficients and location data from which transportation distances were obtained, a total of sixteen ideal airports were recommended that can provide service to their regions, especially during emergencies or after any disaster. In accordance with the suggestions of this research, it is expected that progress will be made in minimizing the loss of time and expense, and especially minimizing the loss of life thanks to the services which can be provided by air transportation in any emergency.No sponso

Biyomedikal telemetri sistemleri için biyouyumlu implant anten tasarımı

xxi, 97 sayfa29 cm. 1 CDÖZETSon zamanlarda medikal cihaz teknolojisinde meydana gelen gelişmeler, biyotelemetri sistemlerinin kullanım alanının artmasına ve bunun sonucu olarak ise biyotelemetri cihazlarının gelişimi sağlamıştır. Biyotelemetri sistemlerindeki temel amaç insan vücudundan hayati verilerin toplanıp kablosuz olarak bir sisteme aktarılması ile hasta takibinin yapılmasını sağlarken, doktorlara hastalık teşhis ve tedavisinde de fayda sağlamaktadır. Biyotelemetri sistemlerinin en önemli bileşenlerden olan anten, biyotelemetri verilerinin harici bir sisteme kablosuz olarak aktarılması işlevini üstlenmektedir. Biyotelemetri sistemin minimal boyutlara sahip olması son derece önemli bir rol oynamaktadır. Bu hedef doğrultusunda biyotelemetri sistemlerinde küçük hacimli, düşük kayıplı, düşük maliyetli, düşük saçılma karakteristiğine sahip olan ve imalatı kolay olan mikroşerit yama antenler biyotelemetri sistemlerde tercih edilebilecek en ideal yapılardır.ABSTRACTThe developments in medical device technology in the last few years have increased the usage area of biotelemetry systems and consequently biotelemetry devices have become more developed. The main purpose of biotelemetry systems is to collect vital values from the human body and transfer them to a system located far away, while providing patient follow-up, it also helps doctors to diagnose and treat disease. The antenna, which is one of the most important components in biotelemetry systems, enables the transfer of biotelemetry data to an external system wirelessly. The minimal dimensions of the biotelemetry system play a vital role. In line with this goal, microstrip patch antennas with small volume, low loss, low cost, low scattering characteristics and easy to fabricate are the best antenna types in biotelemetry systems

AN INVESTIGATION OF TWICE EXCEPTIONALITY (2E) IN THE UK CONTEXT: THE PARADOXICAL COMBINATION OF EXCEPTIONALITIES

Twice-exceptionality (2E) refers to individuals who possess both exceptional intellectual abilities and disabilities. This qualitative exploratory study primarily investigated the experiences of 2E learners and teachers who have previously taught, or currently teach, students with twice-exceptionality. The study examined such lived experiences with reference to philosophical, sociological and socio-cultural theoretical concepts. A combination of interviews and self-administered questionnaires was utilised for data collection following a protracted recruitment process in COVID-19 pandemic and post-pandemic conditions which, it was assumed, had limited consent to participate to seven teachers and five students based primarily in Plymouth. An indicative content analysis of the students` data and reflexive thematic analysis of teachers` data illustrated the importance of acknowledging of paradoxical combinations of ability and disability with additional conditions (e.g., eating disorders and depression). Socialisation difficulties in 2E students with autism and organisational skill problems in high potential students with ADHD were identified. Some teachers observed different characteristics in 2E students such as overconfidence and creative writing skills. However, it was also found that participating teachers were unaware of aspects of 2E and tended to avoid classifying their students as 2E or gifted. Thus, the generation of data on the lack of awareness of 2E provided an additional benefit and contribution to knowledge. The study emphasised the importance of tailored support and inclusive practices, intending to ensure that the voices of 2E students and teachers are heard and to determine their needs. With reference to empirical data and the existing literature, it will contribute the recognition and broader understanding of twice exceptionality, offering valuable insights for educational practitioners, policymakers, and researchers. Further research into this complex intersection of issues in diversity, inclusion, and twice-exceptionality is encouraged to enhance inclusivity and educational systems for 2E individuals

An Introductory Study on

In this study, we mainly dealt with the introduction and comparison of two optimization techniques over the estimated parameters and model results of the Binary Logistic Regression (LR) model. These are the traditional Newton-Raphson (NR) algorithm which requires the differentiable objective function and appropriate starting values related to the parameters and Genetic Algorithm (GA) approach which does not need any strict assumptions as the algorithm NR. The results suggest that NR algorithm and GA give very similar results when the assumptions of NR are satisfied. This indicates that GA could successfully be used instead of the NR method considering its more flexible assumptions. Moreover, if the objective function does not satisfy the differentiability condition, NR could not be used in the optimization process and fails to find the optimum values. Therefore, this study actually reveals the success of GA in the parameter estimation of LR model. All the model outputs are compared in terms of the estimated parameter values, ease of application and convergence rates. Matlab commands are also given with their explanations for GA for researchers studying in this area
