Приложение на изследователския подход в образованието по информатика чрез един популярен математически фокус (Нов поглед към стари идеи)
Authors:   Sofia University, Petrov Philip
Published: December 2022

“Integers and their representation” is the first section from the curriculum for 8th grade high school Informatics education in Bulgaria. The main topic in it is the study of binary numbers. The research shows that the current Bulgarian textbooks have excessive amount of mathematical problems and very few have direct practical applications. Furthermore, they do not use sufficiently the inquiry-based learning approach in the lesson and there are no introductory problems aimed in forcing cognitive dissonance. Good examples on how it can be done in constructivist way are given in the ‘80s textbooks from the experimental Research Group on Education. The article then presents a popular magic trick for teaching binary numbers by the inquiry-based learning. The author provides methodology for its more effective usage as introductory problem for the lesson. The conclusion is that Informatics lessons should use more practical problems with games, tricks and sophisms.

Published: December 2022

Çocukların sağlıklı beslenme alışkanlığı edinmeleri ve sağlıklı gelişmeleri için dengeli ve yeterli beslenmelerinin önemi bilinmektedir. Erken çocukluk döneminde beslenmeyle ilgili faktörlerin anlaşılabilmesi, bu dönemdeki sosyal çevre ve aile ortamının daha iyi anlaşılmasını gerekli kılmaktadır. Çünkü, yapılan çalışmalar, okul öncesi dönemde, ebeveynlerin, özellikle de annelerin besleme sosyalleşmesinde çok önemli bir rol üstlendiğini ortaya koymaktadır. Annelerin beslemeye yönelik davranışlarının, bu konudaki hedef ve inançlarından etkilendiği bilinmesine rağmen bu konuda sınırlı sayıda araştırma bulunmaktadır. Bu çalışmada Türk annelerin çocuklarını beslerken sahip oldukları hedeflerin ayrıntılı olarak incelenmesi hedeflenmiştir. Bu kapsamda 3-6 yaş arasında çocuğu olan 18 anneyle odak grup görüşmeleri yapılmış ve elde edilen verilere tematik analiz uygulanmıştır. Araştırma sonucunda, annelerin sahip oldukları başlıca hedefler, “Sağlık”, “Beceri geliştirme”, “Bağ güçlendirme” ve “Anne odaklı hedefler” olarak isimlendirilmiştir. Elde edilen bulguların, çocukların erken dönem beslenmelerini iyileştirmek amacıyla geliştirilecek olan müdahale programlarının etkililiğini arttırmak için fayda sağlayabileceği düşünülmektedir.

Authors: ERDİL Kübra , KIŞ Salih
Published: December 2022

Osmanlı Devleti’nde Tanzimat ile birlikte yeni bir dönem başlamıştır. Devletin mali idaresi ve bu idarenin üstlendiği görevler yeniden ele alınırken bu dönemde çeşitli kurumlar oluşturulmuştur. Bu kurumların istenen başarıyı yakalayamaması üzerine 1862’de Divan-ı Ali-i Muhasebe adıyla günümüz Sayıştayı teşkil edilmiştir. 1879’da çalışma hayatına başlayan ve çeşitli görevleri bulunan Divan-ı Muhasebat’a devlet malını kullanmaya memur olanları, kullandıkları malları ispata yarayan belgeler üzerinden denetleme yetkisi verilmiştir. Divan’ın bu vazifesini yerine getirirken asıl muhatabı ise muhasib-i mesul olmuştur. Çalışmanın amacı; muhasib-i mesul kimdir, Divan-ı Muhasebat ile bağlantısı nedir? Sorularından yola çıkılarak memurun, Divan-ı Muhasebat heyet-i umumiye kararları ve arşiv belgeleri ışığında genel çerçevede tanıtılmasını sağlamak ve Divan ile ilişkisini ortaya koymaktır. Osmanlı maliyesinde Divan’ın kurulmasına paralel bir şekilde hesap memuru olarak ortaya çıkan muhasib-i mesulün varlığı, hesapları sayesinde Divan’ın mali denetimini çok daha sistemli bir şekilde yürütmesine olanak tanıdığı ve dönemin kurumlarının mali işlemleri hakkında bilgi sunduğu için büyük bir önem taşımıştır.

Abstract: The cooperative output regulation problem (CORP) is an extension of the leader-following consensus problem of multi-agent systems (MASs), and has been studied by two approaches, namely, the distributed observer (DO) approach and the distributed internal model (DIM) approach. The two approaches are, respectively, the extensions of the classical feedforward control approach and the classical internal model approach (for a single system) to the MASs. This paper overviews the CORP by the DO approach with the emphasis on linear MASs. After formulating the CORP, we present the evolution process of three types of DOs and the corresponding solutions to the CORP. Furthermore, some variants and extensions of the DO approach are also briefly surveyed for completeness.

Abstract: Common spatial pattern (CSP) technique has been very popular in terms of electroencephalogram (EEG) features extraction in motor imagery (MI)-based brain-computer interface (BCI). Through the simultaneous diagonalization of the covariance matrices, CSP intends to transform data into another mapping with data of different categories having maximal differences in their measures of dispersion. This paper shows the objective function realized by original CSP method could be inaccurate by regularizing the estimated spatial covariance matrix from EEG data by trace, leading to some flaws in the features to be extracted. In order to deal with this problem, a novel deep CSP (DCSP) model with optimal objective function is proposed in this paper. The benefits of the proposed DCSP method over original CSP method are verified with experiments on two EEG based MI datasets where the classification accuracy is effectively improved.

Mütarekenin 5’inci maddesi gereğince de ordularını terhis etmeye başlamıştı. Mütareke imzalandığında Musul’da 6’ncı Ordu ve ona bağlı 5’inci Tümen bulunmaktaydı. Mütareke şartları gereği de 6’ncı Ordu lağvedilmişti. Bunun yerine bölgede Harbiye Nezaretine doğrudan bağlı 13’üncü Kolordu kurulmuştu. 5’inci Tümen de bu kolorduya bağlanmış ve tümen, Mardin ve çevresinin asayişini sağlamakla görevlendirilmişti. Güney Cephesi’nde 24 Mart 1919’da Urfa’nın işgal edilmesiyle birlikte 5’inci Tümen, Urfa Savunması’na katılmıştı. Urfa’nın 11 Nisan 1920’de istiklaline kavuşmasından sonra 5’inci Tümen, 3 Kasım 1920’de Antep Savunması’na görevlendirilmişti. Tümen burada başarılı muharebelerle Fransızlara darbeler indirmişti. Fakat kuşatma çemberi kırılamadığından açlığa çare bulamayan Antep halkı, 8 Şubat 1921’de Fransızlara teslim olmuştu. Millî Mücadele’de Güney Cephesi’nde Fransızlarla Ankara Hükûmeti arasında barış görüşmeleri başladığı zaman Batı Cephesi’nde Yunanlar Sakarya Nehri’nin doğusuna kadar ilerlemişti. Dolayısıyla bu ilerleyiş, Batı Cephesi’nin kuvvetlendirilmesi zorunluluğunu ortaya çıkarmıştı. Bu kapsamda 5’inci Tümen, Güney Cephesi’nde 9 Kasım 1920’de kurulan 2’nci Kolorduya bağlı olarak Sakarya Meydan Muharebesi’ne katılmak üzere 26 Temmuz 1921’de Batı Cephesi’ne gönderilmişti.

This study aims to evaluate the effectiveness of the United Nations Security Council's resolutions on Cyprus within the framework of the conflict resolution approach. Due to the conflict resolution approach, the position of Turkey, which is on the other side of the conflict and is the guarantor state, is also included in the evaluation with some suggestions. In this context, 152 Security Council resolutions between 1960 and 2021 have been examined. The results show that the Security Council has not been analyzed Cyprus' recent history well. Even the proposal to return to the 1960 Nicosia Treaty is a concrete indicator of this fact. In this sense, the Security Council has not been successful in terms of conflict resolution on Cyprus issue. On the other hand, Turkey, condemned within the framework of the Security Council resolutions, has not been able to explain itself well to the international community regarding Cyprus. The conflict resolution approach at least points that Turkey and Turkish Cypriots have also arguments to put forward for a satisfying solution.

Authors: Mu Bohan
Published: December 2022

Population is the core issue of the development of human society, and predicting the future population changes is an important basis for a country or region to formulate corresponding policies. The theoretical basis of the prediction of population development process is the population development equation, that is, the mathematical model of population development. Aiming at the problem of population structure in China, based on the collection, calculation, collation and analysis of relevant population data, this paper builds a prediction model of population structure in China based on the difference equation method, so as to predict the population of China, and compare it with the original population data to verify and improve the model. The results show that if the current family planning policy remains unchanged, the population structure of China will be aging seriously by 2050. If the two-child family planning policy is implemented, the aging trend of China's population structure will be obviously improved, and it will be an adult population structure after 2030. If the family planning program that is looser than the two-child policy is implemented, the population structure of China will change fundamentally, and the population structure will be in line with the characteristics of younger population structure. In order to provide some reference for the formulation of relevant policies.

Published: December 2022

At present, people pay more and more attention to medical and health issues, and more and more Internet users are eager to obtain medical related knowledge from the Internet. However, despite the large amount of medical data spread on the Internet, it is difficult for ordinary Internet users to effectively obtain and use these data through search engines. To solve this problem, this paper designs and implements a medical question answering system based on knowledge map, so that users can quickly obtain the relevant knowledge in the medical field they want by asking questions, and realize the effective use of medical data on the Internet. At present, there are few question answering systems in the medical and health field, so the medical question answering system designed in this paper has a broad application prospect. The medical knowledge map constructed in the system can also be used in more application scenarios such as medical chat robots in the future, further promoting the process of intelligence in the medical field.
Modeling and numerical simulation of the output spectrum of a broadband Vanadium-doped optical fiber light source
Authors: Shan Yuqi
Published: December 2022

Preliminary results have been achieved in the study of rare-earth doped fiber amplifiers. Further studies on rare earth ion vanadium are discussed in this paper. Based on the rate equation and power propagation equation, a model for the variation of output spectrum with fiber length, doping concentration and pumping power is constructed and solved by MATLAB, ODE45 function to explore the variation of Vanadium-doped fiber output spectrum with control variables from experimental aspects. The numerical simulation results show that the variation is proportional and the output power spectrum is enhanced with increasing fiber length, doping concentration and pump power, respectively. It is observed from the experimental data that the fiber length and doping concentration vary similarly and the output power spectrum expands nearly three times when the optical length and pump power are increased by a factor of two. This model can provide some directions for selecting Vanadium-doped fiber amplifiers and designing vanadium-doped amplifiers.

Published: December 2022

The wide use of comparator reinforces its improvements and innovations. For seeking a breakthrough, a 4-Bit Absolute-value Detector is studied and constructed. Different from common designs, this new version adds an absolute value converter using truth table. Owing to the participation of absolute value detector the comparator can compare the absolute value of the two inputs' value directly in this detector. Furthermore, the detector’s delay and energy consumption which are calculated by critical path data demonstrates the performance of the detector and provides circuit optimization scheme indirectly. The analysis indicates that this improved version's minimum and maximum delay is 50.556 and 75.834 and energy consumption is 39.8% lower when supplied by optimal VDD than 1V VDD. Combining the converter with the comparator, a 4-Bit Absolute-value Detector model with smaller size and higher efficiency is built.

The Dynamic-bias comparator extends its pre-amplifier part with a capacitor and has a smaller power with a smaller input referred noise than Elzakker’s comparator but has a higher delay. The Quad high-speed comparator introduced the Quad into the comparator’s latch part. It has a lower delay and also make the calculation of the output voltage easier for it only depends on the skew factor. The low-power dynamic bias has a cross-couple device on its pre-amplifier part which slows down the discharge of the capacitors. It has a higher delay but lower the energy consumption by 30%.

Lossy and Loss Free Material Research Taking Microstrip Patch Antenna Operating on the Band n261 as the Case
Authors: Zheng Hanwen
Published: December 2022

The focus of this paper is to discuss the loss mechanism of the antenna and its effect on the antenna performance. This paper will follow the order of design basis, design idea, design content, and design results. Based on an antenna design for an n261 band, experiments are conducted in CST studio using different materials under lossy and lossless conditions. It includes 8 different sets of experiments. The lossy material will perform worse than the lossless material by processing the data through the program. When designing antennas, the performance of lossy materials will be worse. The material has a low tangential loss, and the loss of the antenna will be reduced. When designing an antenna, the antenna’s performance should be measured comprehensively by S11, Z11, as well as radiation efficiency and electric field results, instead of looking at only one parameter. Meanwhile, microstrip antenna design can be used to design antenna arrays or multi-band antennas.

Research on fairings with different aspect ratio under subsonic flow Based On FLUENT
Authors: Hu Keqing
Published: December 2022

When rocket flying at high speed, large air resistance will generate at the front and around the rocket fairing. Results in significant reduction of the rocket's range and speed. The research shows that the air resistance produced by the fairing accounts for more than half of the total resistance of the rocket. As the shape of fairing is axisymmetric, a 2D model with triangle mesh was used for simulation to analyze the pressure around fairing. Eight group of fairing with aspect ratio from 0.25 to 2 were studied under the compressible non viscous airflow with 200 m/s incoming speed. The air resistance decreases with the increase of the aspect ratio, and the high pressure area around the fairing also reduces from more than a half to one third of the total fairing length. In these eight groups of fairings, the fairing with aspect ratio 2 performs best, receives the minimum air resistance and with pressure mainly distributed at the front end of the fairing.

Authors: RIAZ Z
Published: December 2022

Burns are medical conditions that are the fifth major reason behind non-fatal and adult injuries due to compulsiveness and a lack of risk calculation ability. 1.2 In Pakistan, 2500 children suffer serious burns that necessitate medical attention each year, with 15,000 requiring hospitalizations. The WHO (World Health Organization) has revealed in the reports that child burn mortality is greater (seven times) in countries with low and middle-income backgrounds compared to those with high incomes. Polypeptides of varied molecular weights were discovered in MCPs. These MCPs come from Nile tilapia’s skin with the help of enzyme-aided hydrolysis, with polypeptides with a molecular weight smaller than 5kDa accounting for 99.1 percent of the total. The key molecular conformations within MCPs were casual coil, according to FTIR. The MCPs application was done in the quantity of 50g/ml. The treatment significantly affected scratch closure in an in vitro scratch assay. MCPs improve wound healing in child burn skin with a deep partial-thickness scald wound. As a result, it was concluded that the MCPs derived from Nile tilapia‘s skin have promising wound care effects and results.
