Authors:Mustafa Al-asadi; Oğuz Karan Abstract: Monopole Microstrip Antennas (M-MSAs) are widely used because of their price, ease of manufacturing, and compact size, making them ideal for portable applications. Nowadays, Ultrawide Band (UWB) technology, used in wireless applications, relies on this antenna. The UWB frequency range is 3.1 to 10.6 GHz, allowing low-power wireless applications such as wireless music, personal localization, radio frequency recognition, radar, and HD video dissemination. However, this frequency band's broadness increases interference. This contribution research formulates simulates, and optimises a modified small-square M-MSA that meets UWB technology's huge bandwidth requirements. A square radiated patch, a dielectric material with a thickness of 1 mm and 4.7 relative permittivity, a partly ground plane printed on the patch's face, and a coplanar waveguide feed make up the M-MSA design. The M-MSA design is modified to reduce the patch's bottom corners and change its proportions to enable compatibility with the UWB complete band. A U-shaped aperture on the patch should be etched to produce a bandgap in UWB frequencies, reducing interference. Filling the aperture with graphene allows bandgap tunability. The graphene's bandgap dissipates with DC voltage, but without biassing, its high impedance restricts aperture current flow. The bandgap's effect is seen at 3.87-4.85 GHz. After simulation and tweaking, gain and efficiency improved significantly. The bandgap region, which was chosen to reduce interference from military fixed communications, mobile communications, unmanned aerial vehicles, short-range radio links, satellite communications, and the low band of 5G, also exhibits a significant increase in attenuation and gain degradation.

Authors:Saif Al-jumaili Abstract: Over the last few decades, neuroimaging, particularly magnetic resonance imaging (MRI), has played a significant sessional part in studying brain functions and diseases. MRI images, combined with unique ML approaches and developed tools during these years, have opened up new opportunities for diagnosing neurological illnesses. However, due to the apparent symptoms that are similar to each other, brain illnesses are regarded as difficult to precisely detect. This research examines a newly developed algorithm (ParkinsonNet) to classify Parkinson's disorder into two unique classes which are Control (healthy) and Parkinson's (PD), this method is one of the deep learning approaches, Convolutional neural networks (CNN). CNN is one way that may be used to classify a range of brain illnesses such as Parkinson's. We employed a freshly constructed CNN technique from scratch, and we got 97.9% accuracy which is considered outstanding compared with recently published articles using the same dataset PubDate: Sun, 31 Dec 2023 00:00:00 +030
Authors:Ali Mahmood Aswad Aswad; Çağatay Aydın, Murtaza Farsadı, Doğu Çağdaş Atilla Abstract: Mikrogrid, birçok dağıtılmış üretimin (DGs) sorunsuz bir şekilde kurulumu için yeni kavramsal güç sistemlerinden biridir. Mikrogridlerin çoğu geleneksel güç sistemlerinde olduğu gibi AC dağıtımını benimserken, DC mikrogridler fotovoltaik (PV) sistem, yakıt hücresi ve ikincil batarya gibi DC çıkış tipi kaynaklarla iyi bir bağlantı için önerilmekte ve araştırılmaktadır. Ayrıca, sistemdeki yükler DC güç ile beslenirse, kaynaklardan yüklere olan dönüşüm kayıpları AC mikrogrid ile karşılaştırıldığında daha azdır. Bu makale çalışmasında, DC mikrogrid yüklerin çoklu tipleri ve güç kaynağının iki tipi (AC grid ve PV matrisi) için Matlab/Simulink kullanılarak simülasyonları yapılmıştır. Maksimum güç noktası izleme sistemi (MPPT), PID denetleyicisi kullanılarak uygulanılmıştır, Önerilen sistem için simülasyon, 1000 W/m² ve 25ºC'de Matlab/ Simulink kullanılarak yapılmaktadır. Maksimum güç noktası takip sistemi (MPPT), PID(Oransal, İntegral, Türevsel) kontolcü kullanılarak uygulanılmıştır, bu çalışmada PV panel maksimum güç ile çalışmaktadır. PV dizisinden üretilen gerçek güç ile yükün gerçek gücü arasındaki fark AC grid tarafından sağlanılmaktadır. Bu sistemin diğer avantajı, düşük dönüşüm kaybına sebep olan DC/DC dönüşüm basamağının olmaması ve sonunda toplam sistem verimliliğini arttırmasıdır. PubDate: Sun, 31 Dec 2023 00:00:00 +030
Authors:Ece Bülbül; Ruşen Yamaçlı Abstract: It is necessary to take measures in all sectors against the global climate change problem, which has increased in recent years. These measures are; especially in the construction sector, where energy and resources are spent a lot, it should be in the planning part of the design, construction and post-construction management phase of the building and the urban environment. More attention should be paid to sustainability criteria (economic, environmental and social) in stadium structures, which are mega structures and have many examples due to the importance given to football abroad and in our country. Within the scope of this study, the examples of stadiums abroad that attach importance to sustainability criteria are examined, the current situation of Başakşehir Fatih Terim Stadium and Eryaman Stadium, which are located in Istanbul and Ankara, which have the highest population in our country, and what needs to be done to become sustainable stadiums are mentioned. As a result, a road map has been put forward for the sustainability of the existing stadiums in Turkey and what needs to be done in the design and construction of the new stadiums, based on these two examples examined.

Authors:Gizem Yeğen; Cagla Senel, Saadet Kevser Pabuccuoğlu, Buket Aksu Abstract: Pharmaceutical development and authorization stages have high requirements that increase labour and costs. Risks for product quality and process robustness also increase in parallel with complex practices existing in the pharmaceutical industry and emerging as a result of developments. Although it is challenging to eliminate parameters leading to increased risks, there is need to appropriately manage the risks likewise arrange decision making processes. Designing and optimizing formulation and production processes to deliver the predetermined product quality is known as Quality by Design (QbD) in pharmaceutical development. In terms of data and knowledge, QbD can be carried out using a variety of technologies in this process. Mathematical modelling is one of these tools allows for the quick formation of subject knowledge, which may subsequently be used in an independent or integrated manner and to produce Design of Experiments (DOE). Response surface method (RSM), Artificial Neural Network (ANN), Genetic Algorithm (GA) are some of the assistive technologies used in mathematical modelling that enables to enlighten the effect of formulation and process variables on product quality attributes. The use of advanced mathematical modelling techniques in formulation and process development has become widespread and it appears to be beneficial in different areas of pharmaceutical development.

Authors:Behzat Gökçen Demir; Ali Koray Özdoğan, Akın Akbulut Abstract: In Anatolian lands, natural stones have been at the forefront in the construction of living spaces and economic activities from past to present. Travertine is one of the most important rocks among the rocks considered as natural stones. Travertines, one of the oldest natural stones used in Anatolia, are also very important in terms of tourism and culture. In particular, Denizli travertine, which has a geographical sign, is a good example of this situation. While the travertines that are still being formed in the Denizli region are in the position of a cultural, historical, tourism and promotional ambassador, the geologically older ones are very important for the natural stone sector. Apart from Denizli region, Kütahya, Ankara, Karabük, Kayseri and Sivas regions are important production areas in travertine mining. Economically utilised travertines are divided into two as scientific and commercial travertines. Commercial travertines are generally young aged limestones. Travertine production in Türkiye has increased in recent years compared to the past years. In terms of quantity and value in terms of exports, block and processed travertine have significant proportions in natural stone exports. In this study, the importance of travertine for Türkiye is emphasised by giving information about its properties, mining, history and usage. PubDate: Sun, 31 Dec 2023 00:00:00 +030
