Authors: Boran Didem , Çürük Selva Muratoğlu
Published: November 2024

Günümüz kablosuz haberleşmesinde kullanılan radyo frekansları bandı, hızla artan büyük miktarda veri transferi ihtiyacını karşılamakta zorlanmaktadır. Bu nedenle bilim dünyası elektromanyetik spektrumda Terahertz (THz) boşluğu olarak adlandırılan frekans bandını kullanarak yüksek veri hızına ulaşmayı amaçlamaktadır. Farklı ortamlarda kullanılması amaçlanan kablosuz THz sistemlerinin karşılaştığı kanal, performans açısından incelenmesi gereken öncelikli konulardan birisidir. Özellikle iç mekânlarda kanal çokyollu yapısı nedeniyle karmaşıktır ve literatürdeki çalışmalar sınırlıdır. Bu çalışmada öncelikle 0,1 - 10 THz bandında yol kaybının sebep olduğu frekans seçici kanal yapısı incelenmiştir. Yüksek frekans bandında bu durum daha kritiktir ve ani zayıflamalar mesafe, ısı ve nemle ilişkili olarak ciddi artış göstermektedir. Verimli bir haberleşme için bu zayıflamaların olmadığı bant aralıkları belirlenmiştir. Ardından, iç mekân çokyollu kanalın modellenmesi için kullanılan ışın izleme tekniği THz kanallarına uyarlanmış, kanal yapısı incelenmiştir. Simülasyonlar güçlü zayıflama nedeniyle yansımaların görüş hattına göre zayıf kaldığını göstermiştir, ancak çokyollu kanal yapısı yine de frekans seçici bir kanala neden olmaktadır. Oda boyutunun artması ve vericinin tavanda konumlanması frekans seçiciliği azaltsa da düz sönümlemeli bir kanal için yansımaların azaltılması gerekmektedir. Son olarak, ışın izleme modeli ile literatürde bulunan üstel kanal modeli kıyaslanmıştır. Kıyaslama sonucunda nispeten basit sayılan üstel model ile THz kanalın kolayca modellenebileceği sonucuna varılmıştır.

Published: November 2024

Doğal afetler sonucunda fiziksel, sosyal, çevresel ve ekonomik kayıplar meydana gelmektedir. Afet yönetimi faaliyetlerinin yetersiz olması ve/veya planlanan faaliyetlerin eksik uygulanması sebebiyle kayıpların arttığı bilinmektedir. Doğal afet gerçekleştikten sonraki ilk 72 saat içinde yapılan müdahale ile can kayıpları azaltılabilmektedir. Bu süreçte hızlı müdahale için yardım malzemelerine ve ekiplere ihtiyaç duyulmaktadır. Bu sebeple acil yardım malzemelerinin afet bölgesine hızlıca ulaştırılması çok önemlidir. Belirli yerlerde yardım malzemelerini içeren afet depoları bulunsa da afet sonrası sıklıkla ortaya çıkan ulaşım problemleri sebebiyle malzemelerin kısa sürede afet bölgesine ulaştırılmasında sorunlar yaşanmaktadır. Afet konteyneri olarak bilinen, içerisinde darbeli matkaplar, ilaçlar, sedyeler ve jeneratörler gibi acil yardım malzemeleri stoklanabilen konteynerlerin hazırlanması ve uygun yerlere yerleştirilmesi uzmanların da vurguladığı gibi afetten sonraki süreçte hızlı ve etkin müdahale için hayati önem taşımaktadır. Afet bölgesindeki görevliler, organize yardım ulaşıncaya kadar geçen zamanda, beklemeden, kullanıma hazır durumda olan konteyner içindeki yardım malzemelerine erişerek hızlı müdahale sağlayabilmekte ve böylece kayıplar en aza indirilebilmektedir. Bu motivasyonla, bu çalışmada afet konteynerleri ile ilgili kapsamlı bir araştırma yapılarak mevcut durum analiz edilmiştir. Literatürde afet konteynerleri ile ilgili kısıtlı sayıda yapılan çalışmalar incelenmiş ve uzman görüşleri ışığında afet konteynerlerinin yönetimi ile ilgili eksiklikler ve duyulan ihtiyaçlar ortaya konularak yönetimsel problemler tanımlanmış ve farklı çözüm yaklaşımları önerilmiştir.
Geri dönüştürülmüş karbon siyahı takviyeli doğal kauçuk karışımlarında yorulma çatlak ilerlemesi karakterizasyonu
Authors: Haydari Onur , Söylemez Emrecan
Published: November 2024

Geri dönüştürülmüş karbon siyahı (RKS), geleneksel karbon siyahına (GKS) kıyasla daha düşük yüzey alanına ve daha yüksek kül içeriğine sahiptir. Bu sebeple, RKS'nin doğal kauçuk (NR) karışımındaki dispersiyonu GKS'ye göre daha zor olabilir. Ancak, RKS'nin GKS'ye göre daha zor disperse olması nedeniyle, hamurda RKS'nin GKS'ye göre dispersiyonu daha zorlu bir süreçtir ve bu süreç, karıştırma süresine daha fazla bağımlılık gösterir. Bu çalışma, RKS ile takviye edilmiş vulkanize NR karışım numunelerinin yorulma çatlak ilerleme hızını, GKS ile takviye edilmiş vulkanize NR karışım numunelerinin yorulma çatlak ilerleme hızıyla karşılaştırmaktadır. RKS ile takviye edilmiş NR'nin yorulma çatlak ilerleme hızının GKS ile takviye edilmiş NR'a kıyasla daha yüksek olduğu gözlemlenmiştir. Her iki karışım modeli için yorulma çatlak ilerleme hızı ve gerinme enerjisi arasındaki ilişki modellenmiş olup, analizler ve çıkan sonuçlar tasarımcıların hasar toleransını dikkate alarak döngüsel ekonomi kavramına uygun alternatif kauçuk karışımları seçmelerine olanak tanır.

Impact of Climate Deviation on Reproductive Profile of Nile Tilapia, Oreochromis niloticus (Linnaeus, 1758) from the Tons River, India
Authors: Amitabh Chandra Dwivedi , N Mishra
Published: November 2024

Nile tilapia, Oreochromis niloticus is among the leading farmed species around the world as well as a powerful invader in many countries globally. Studies were undertaken during the period from February 2019 to January 2020 from the lower stretch of the Tons River at Prayagraj, Uttar Pradesh, India. During the sampling period, 683 fish specimens of Nile Tilapia, Oreochromis niloticus (336 males and 347 females) were collected and studied for evaluation of sex ratio and sex structure. The sex ratios of male and female fishes were very close and reported 1.0:1.03 in the stock. The male ratio was higher in the small size group of fish with 81 to 200 mm size groups and 411 to 470 mm size group. The sex structure of males and females was observed at 49.19% and 50.81%, respectively in the case of stock. The female proportion was recorded as a minimum with 37.50% in the 441-470 cm size group and highest with 54.84% in the 381-410 mm size group. However, the male proportion was reported lowest at 45.16% in the 381-410 mm size group and highest at 62.50% in the 441-470 mm size group. In the present findings, O. niloticus was found to reach maturity starting below 138 mm of total length, taking individual fish. The fishes breed in the months of March to June and September to November of the year. The number of eggs per individual ranged from 393 to 4338 in the size of fish varied from 138-452 mm. The reported fecundity and sex ratio of O. niloticus indicated that the climatic condition or environmental condition of the Tons River was most suitable. The environmental condition (especially temperature) of the Tons River at Prayagraj is slightly warm compared to the Ganga River which is very favourable for O. niloticus. The water current velocity of the Tons River is very poor. Both parameters are very helpful for the stability of O. niloticus in the Tons River at Prayagraj. The high fecundity of O. niloticus in the Tons River at Prayagraj could probably be a result of a combination of different causes such as climatic conditions, habitat structure, food abundance, water quality, and quality of food. Therefore, the present study aimed to update the information on the sex ratio, sex structure, and fecundity of O. niloticus with respect to climate from the Tons River, India.

Authors: Doğan Yahya , Özdemir Cüneyt
Published: November 2024

Skin cancer is a disease characterized by the uncontrolled proliferation of skin cells, typically manifesting as lesions or abnormal growths. Early diagnosis is critical for improving treatment outcomes. This study proposes an innovative approach to skin cancer diagnosis by integrating modern deep learning models with traditional machine learning algorithms. A three-phase methodology was developed. In the first phase, meaningful features were extracted from skin lesion images using various transfer learning models, including Xception, VGG16, ResNet152V2, InceptionV3, InceptionResNetV2, MobileNetV2, EfficientNetB2, and DenseNet201. In the second phase, dimensionality reduction was performed using Principal Component Analysis (PCA). In the final phase, the reduced feature sets were classified using K-Nearest Neighbors (KNN) and Random Forest (RF) algorithms. Experimental results demonstrated that the highest accuracy of 91.28% was achieved through the combination of DenseNet201 for feature extraction, PCA for dimensionality reduction, and Random Forest for classification. These findings highlight the effectiveness of integrating transfer learning models, dimensionality reduction techniques, and machine learning algorithms in enhancing the accuracy of skin cancer diagnosis.

Advice utilization in combined human-algorithm decision making: An analysis of preferences and behaviors
Authors: Sachin Panda , Schecter Aaron
Published: November 2024

As artificial intelligence (AI) becomes more pervasive, humans will interact with autonomous agents more frequently and in deeper ways. While there is a significant body of work addressing the interface between a single human and a single AI agent, less is known about how individuals react to AI when they are part of human-agent hybrids, namely multiple humans and potentially multiple AI. These hybrid forms are unique in that advice is often given simultaneously, i.e., a human decision maker evaluates advice from other humans and algorithms at the same time. This scenario presents a boundary condition on the extant literature, as it is unclear how a human decision maker will differentially appraise a human advisor compared to an algorithmic advisor when their advice is simultaneous. This study presents the results of three experiments asking individuals to estimate property rental prices with the support of both human and algorithmic advice. We tested whether explicitly labeling an advisor as an algorithm rather than a human impacts how individuals perceive both the algorithm and another human advisor. We also examined the role of conflicting advice during simultaneous evaluation. Based on the results of 904 participants, we found that labeling an advisor as an algorithm resulted in a significantly significant algorithmic appreciation bias, even when an equivalent human was present. Further, we found that uncertainty induced by conflicting information weakened the appreciation effect, while agreement among advisors resulted in the strongest behavioral responses.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Samsonenko Daria
Published: November 2024

Background. The Baroque era, which is characterized by its grandeur, dramatic color and exquisite ornamentation, left a bright mark on Ukrainian lands. However, the spread of Baroque architecture, art and culture was not only a stylistic phenomenon; it was deeply intertwined with the contemporary social-political and spiritual-cultural development. Understanding the deep factors that contributed to the spread of Baroque in Ukrainian territories requires the study of the multifaceted dynamics that shaped the culture of this era. Methods. A systematic review of the literature related to the Ukrainian Baroque in order to collect and generalize the existing knowledge about this period. Comparative analysis, comparing Ukrainian baroque with other national baroque schools and highlighting common and unique features. Results. It is revealed and outlined that the Ukrainian Baroque is an important period in the cultural history of the country, which combines national and pan-European influences, religious and social aspects, as well as the interaction of various cultural currents. Reflecting the diversity and complexity of Ukrainian society and its cultural traditions. Conclusions. The spread of baroque in Ukrainian lands was not a monolithic phenomenon, but a complex interaction of socio-political, religious and cultural factors. The adoption of Baroque aesthetics served many purposes, including the assertion of political power, the expression of religious piety, and the cultivation of cultural identity. Ukrainian Baroque appeared as a dynamic synthesis of local traditions and external influences, personifying the richness and diversity of the region's historical and cultural heritage
HUKIV CUSTOMS: FIGHT AGAINST SMUGGLING ACTIVITIES ON THE POLISH-SOVIET BORDER IN 1923–1924
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Humennyi Serhii
Published: November 2024

Background. The article, based on archival sources, analyses the anti-smuggling activities of a small customs body in a fairly limited period of time – Hukiv Customs in 1923–1924. The relevance of the proposed microhistorical research is added to the insufficient scientific development of the activities of Hukiv Customs on the Polish-Soviet border, which was caused by the short functioning of this customs body (which, during the research period, existed in various forms from 1918 to 1925) and the need to study methods of combating smuggling by Soviet customs bodies. Methods. The research is based on the principles of historicism and objectivity. A complex of general scientific and special historical methods was applied: methods of synthesis, induction and analysis, as well as historical and typological methods. Results. Analysing the reporting documentation of the Hukiv Customs in 1923–1924 (it controlled the Soviet section of the border on the Zbruch River between the villages of Zbryсh or, for a certain period, Zhabyntsi and Zaluchchia, now the Kamianets-Podilsky district of the Khmelnytskyi region), it was possible to establish the peculiarities of the functioning and anti-smuggling of this customs division in the considered period. It seems important to investigate the Hukiv Customs during the period of functioning of transitional, unstable customs control rules and the Customs Statute of 1924, which established the state monopoly on foreign trade. The dynamics of changes in contraband flows (in the initial period of existence of the "Zbruch border", immediately after the famine of 1921–1923), their composition and the export-import ratio were traced. On the basis of the study of the documentary base, localities with the highest percentage of smuggling risks have been localized. Particular attention is paid to the complicity of representatives of customs protection or Soviet special services in smuggling processes. Also, on the basis of information from the Soviet side, a historical and statistical study of illegal trade in the area of the Skala customs office (Skala, Tarnopol Voivodeship) of the Republic of Poland, which operated in the territories adjacent to the Hukiv Customs House, was conducted. Conclusions. The proposed article examines and analyses transformational phenomena (organized and personal smuggling, the ratio of export-import volumes of "packing", currency relations associated with illegal trade, development of trade cooperation) taking into account the historical context of the development of the fight against contraband flows in the area of the Soviet Hukiv Customs in 1923–1924

The influence of the composition of the combed grain heap on the preliminary separation of loose grain
Authors: Ozhereliev Viktor N. , Nikitin Viktor V. , Savin Vladimir Y. , Sinyaya Natalia V.
Published: November 2024

BACKGROUND: The paper reviews the state of the problem of grain harvesting by the method of combing plants on the root. Attention is focused on the potential economic efficiency of the method and on the scientific and technological problems hindering its widespread implementation. In particular, in order to reduce the degree of crushing of loose grain, it is necessary to separate it preliminary and prevent it from entering the threshing device. It is proposed to remove grain directly on the lattice bottom of the inclined chamber of the combine harvester. The scientific hypothesis of the study suggests that in order to improve separation, it is advisable to remove a significant part of light impurities from the pile directly preliminary in the body of the combing adapter.
AIM: Evaluation of the efficiency of separation of loose grain by removing a significant part of light impurities from the combed pile before it enters the inclined chamber.
METHODS: To confirm the hypothesis, the experiment was conducted in which a combed grain pile of wheat of the «Moskovskaya 56» variety of different component composition was fed to a lattice surface equipped with a scraper conveyor. The weight content of the grain varied from 70 to 100%. The experiment took into account the proportion of loose grain that passed through the holes of the grate at its length of 920 mm and the width of the holes of 12 mm. It ranged from 65 to 80% as the content of loose grain in the pile increased.
RESULTS: According to the study results, it was found that the passage of loose grain through the openings of the lattice bottom varies between 65-80%. At the same time, a decrease in the mass fraction of loose grain in the pile reduces its passage through the openings of the lattice surface by 15%.
CONCLUSION: Preliminary removal of light impurities from the combed grain pile, comparable in size to loose grain, can be carried out by using an inertial separation system. Reducing the proportion of light impurities in the pile entering the combine harvester cleaning system makes it possible to significantly increase the efficiency of its operation.

Infertility is an illness recognised by the World Health Organisation (WHO) that refers to the inability to achieve a clinical pregnancy after engaging in regular, unprotected sexual intercourse for a period of 12 months or more. The incidence of primary infertility in India ranges from 3.9% to 16.8%. Hysteroscopy has emerged as a crucial technique for diagnosing infertility, providing a direct view of the uterine chamber to detect any possible abnormalities. The objective of this research is to analyse the use of diagnostic hysterolaparoscopy (DHL) in the evaluation of infertility.

This research was a retrospective observational study that included 150 female patients who had a previous history of infertility. The study was done from May 2022 to September 2023. Information on the social and demographic characteristics of individuals and their medical history pertaining to infertility were collected by conducting interviews using a pre-tested, semi-structured questionnaire. Every participant took Dual-Hemisphere Language testing, and the gathered data were organised in Microsoft Excel. The significance threshold was established at 5% with a significance level of α = 0.05.

: Out of the 150 patients that received DHL, 89 (59.33%) had primary infertility, whereas 61 (40.67%) had secondary infertility. Laparoscopy detected abnormalities in 35 (39.3%) of the individuals with primary infertility and 26 (42.6%) of the cases with secondary infertility. Abnormalities identified during hysteroscopy were 12 (13.4%) of the individuals with primary infertility and in 6 (9.83%) of the cases with secondary infertility. The prevalent abnormalities detected during hysteroscopy were uterine synechiae, fibroids, and uterine septa. The incidence of tubal obstructions was higher in the primary infertility group compared to the secondary infertility group.

Diagnostic hysterolaparoscopy (DHL) is a very useful method for assessing infertility, namely in identifying adnexal adhesions, endometriosis, and uterine septa. In addition, DHL has the ability to detect several structural abnormalities in the uterus, fallopian tubes, and pelvis, which may assist in formulating suitable treatment strategies. So, both diagnostic and therapeutic intervention can be done at same sitting.

Abortion is defined as the spontaneous and induced termination of a pregnancy before foetal viability. Abortions accounted for one-third of all pregnancies, and nearly half of the pregnancies were unintended. An effective way to prevent the burden of unsafe abortion could be access to safe abortion services. Both surgical and medical methods are available for abortion or the termination of a pregnancy. Thus, we compare the two methods of medical and surgical abortions in this study.

The study was conducted on women attending obstetrics and gynaecology OPD for seeking treatment for abortion in the first trimester. 100 women were allocated to Group A, who opted for medical treatment, and Group B, for surgical abortion. Two groups were compared in terms of clinical parameters like blood loss, aftereffects, post-procedure visits, and efficacy.

In group A, 14% of women had minimal bleeding, 70% had moderate bleeding, and 6% had heavy bleeding. In group B, 72% had minimal bleeding, 28% had moderate bleeding, and no one had heavy bleeding. The combined complication rate in surgical abortion was significantly lower as compared to medical abortion, but the difference in clinical efficacy is not significant.

The medical method is a good alternative to surgical abortion. The medical termination was associated with more bleeding and more post-procedural aftereffects, although both procedures were comparable in clinical efficacy.

Concomitant chemoradiation(CRT) with weekly Cisplatin is presently the treatment of choice for locally advanced cases of carcinoma cervix. Despite it’s proven benefit in reducing disease recurrence by as much as 50%, our search is on for further improvement of treatment efficacy.

This trial was done for comparing the response and toxicity of CRT with weekly Paclitaxel versus weekly Cisplatin in carcinoma cervix with locally advanced staging.

Biopsy proven cases of squamous cell Ca stage IB2 to IVA were randomized into two arms (1:1 ratio). Arm A- patients received concomitant weekly cisplatin(40mg/m2)for 5 weeks during external radiation. For arm B-patients received weekly paclitaxel(60mg/m2) for 5 weeks concomitantly. EBRT dose of 50.4 Gy in 28 #was given alongwith followed by brachytherapy. Institutional and ethical clearance was obtained.

Paclitaxel, when given concurrently with EBRT in cases of carcinoma cervix with locally advanced staging produces comparable response to that of cisplatin.

Multiple factors affect fetal birth weight (FBW) and fetal well-being. This study aims to evaluate how hypertension affects FBW and the area of Wharton's jelly (WJ). It also seeks to explore the protective properties of WJ by analyzing its relationship with FBW in normal and pre-eclamptic (PreE) pregnancies.

Eighty umbilical cords (UCs) were analyzed, with forty from normotensive pregnancies and forty from PreE pregnancies. The cross-sectional area of the UC and vessels was measured using a vernier scale and ocular micrometer. The WJ area was calculated by subtracting the vascular area from the UC area, and then compared with FBW.

In this study, the normal group had an average FBW of 2547.25 ± 240.79 grams and WJ area of 35.28 ± 8.42 mm, while the PreE group had an average FBW of 2424.75 ± 234.36 grams and WJ area of 29.04 ± 8.09 mm. Both FBW and WJ area were significantly lower in the PreE group. There was a strong positive correlation between WJ area and FBW in both the normal group (r = 0.895, p<0.0001) and the PreE group (r = 0.850, p<0.0001).

The findings indicated that both FBW and WJ area were notably lower in the PreE group compared to the normal group. Furthermore, a strong positive correlation between WJ area and FBW was observed in both groups. These results emphasize the importance of WJ in fetal growth and highlight the significance of its quantity in determining birth weight.

The process of orthodontic bonding should be accurate for excellent clinical outcome. For clinicians and postgraduate residents, accurately determining the center of the clinical crown—where the bracket should ideally be placed to express the built-in prescription—poses a challenge. Typically, gauges are used to place the bracket accurately both in horizontal and vertical plane of space. In an effort to streamline the bonding procedure and eliminate the need for drawing lines on the teeth, we have enhanced the bracket-holding tweezer. This modification involves incorporating a diode laser, aiming to simplify the assessment of the clinical crown's center for clinicians, ultimately contributing to a more precise bonding procedure.

Voice Control System for Robotics in a Noisy Environment
Authors: Lavrynenko Oleksandr
Published: November 2024

This paper analyzes the effectiveness of the developed voice control system for robotics based on MFCC and GMM-SVM under the influence of interference in the communication channel. The system allows characterizing individual features of speech signals with their subsequent classification and making a reliable decision on the interpretation and execution of voice commands by robotic equipment. The proposed voice control system for robotics based on MFCC and GMM-SVM is implemented using the following technologies: 1) selection of active speech areas by calculating the short-term energy and the number of zero crossings between adjacent frames of the speech signal; 2) adaptive wavelet filtering of the speech signal, where it is necessary to generate threshold values, which will reduce the impact of additive noise; 3) selection of recognition features, which are used as mel-frequency cepstral coefficients; 4) classification of recognition features based on mixtures of Gaussian distributions and the support vector method using the linear Campbell kernel and the principal component method with a projection on latent structures, which will reduce errors of the 1st and 2nd kind.
