Published: May 2023

West Sumatra is recorded to have an electrification ratio of 92.96%. Every year this figure will continue to increase, with the increase in the electrification ratio in West Sumatra, the quality of the required electric power will increase. Meanwhile, an increase in the electrification ratio will cause a decrease in the quality of electric power. The power quality of the electric power system is affected by disturbances. In other words, some disturbances occur in the electric power system which causes a decrease in power quality. The disturbance is in the form of external factors and internal factors. External factors include lightning, fallen trees, and others, while internal factors include short interruptions, voltage swells, voltage and current transients, and voltage flicker. Of these disturbances, the discussion will be focused on voltage flicker disturbances. Voltage flickers have several pathways, including causing malfunctions in the protective relay, and voltage surges that can cause bright and dim flickering of lighting lamps. The purpose of this final project is to create a tool to detect the presence of Voltage Flicker using the fast Fourier transform method so that it can observe the flicker that occurs with fast Fourier transform waves in Matlab applications.

Not much different from the working principle of ordinary aircraft, Unmanned Aircraft also uses an airfoil design on the wings to be able to manipulate aerodynamics so that the aircraft can fly. it's just that airplanes are usually controlled by pilots while Unmanned aircraft are controlled remotely connected by radio signals. To carry out its rift mission, the aircraft is equipped with an autonomous system by determining way-points assisted by GPS so that later the aircraft can fly more precisely than manually controlled directly by humans. When flying automatically, the aircraft is often constrained by failed take-offs and when flying on missions the position of the aircraft making turns (Loop Maneuver) is often imprecise. Therefore, the time taken by the aircraft to perform the loop maneuver is calculated using the circle circumference formula and divided by the average speed of the aircraft.

Robust capped norm dual hyper-graph regularized non-negative matrix tri-factorization
Authors: Yu Jiyang , Pan Baicheng , Yu Shanshan , Leung Man-Fai
Published: May 2023

Non-negative matrix factorization (NMF) has been widely used in machine learning and data mining fields. As an extension of NMF, non-negative matrix tri-factorization (NMTF) provides more degrees of freedom than NMF. However, standard NMTF algorithm utilizes Frobenius norm to calculate residual error, which can be dramatically affected by noise and outliers. Moreover, the hidden geometric information in feature manifold and sample manifold is rarely learned. Hence, a novel robust capped norm dual hyper-graph regularized non-negative matrix tri-factorization (RCHNMTF) is proposed. First, a robust capped norm is adopted to handle extreme outliers. Second, dual hyper-graph regularization is considered to exploit intrinsic geometric information in feature manifold and sample manifold. Third, orthogonality constraints are added to learn unique data presentation and improve clustering performance. The experiments on seven datasets testify the robustness and superiority of RCHNMTF.

Published: May 2023

The study proposed an Adaptive Neuro-Fuzzy Inference Systems (ANFIS) model capable of predicting sediment deposited in a dam and sediment loss-in-transit (SLIT) using the potential of a formulated mathematical relation. The input parameters consist of five members viz: the rainfall, the slope, the particle size, the velocity, and the computed total volume of sediment exited from two prominent gullies for 2017, 2018, and 2019. The outputs are the total volume of sediment deposited at the adjoining Ikpoba dam for 2017, 2018, and 2019, respectively. The Ordinary Least Square (OLS) regression model on sediment volume retained all covariates with p<0.05, explaining 93.8% of the variability in the dataset. The multicollinearity effect on the dataset was assessed using the Variance Inflation Factor (VIF) which was found not to pose a problem for (VIF<5). The model was validated using the (MSE), the (MAE), and the correlation coefficient (r). The best prediction was obtained as: (RMSE = 0.0423; R2 = 0.947). The predicted volume of sediment was 842,895.8547m3 with an error of -0.3295344% and the predicted volume of SLIT was 57,787.98m3 which is an indication that ANFIS performs satisfactorily in predicting sediment volume for the gullies and the dam respectively

The shortage of electricity in rural areas despite the hydraulic potential they possess is becoming a challenge for Benin. To date, nearly 140,000 people spread over the 42 lakeside villages of this country live in energy inaccessibility, insecurity and poverty. To overcome this situation, the present study is therefore interested in the production of electrical energy on an experimental basis in low water periods thanks to an Archimedean screw turbine which operates at low flow rates and height of fall on the river. Djonou located in southern Benin a few kilometers from the University of Abomey-Calavi. The geometrical and hydraulic parameters of the screw were therefore determined and the device was modeled using Autocard software. A prototype was then made with local recycled materials and tested on the river. The screw specifications indicate an inside and outside radius of 0.072 m and 0.135 m. The length of the screw was set at 0.46 m for a blade radius estimated at 0.137 m. The number of screw blades is equal to 2 with a flow rate of 0.049 $ m^{3}/s $. The inclination angle of the screw is $25^{\circ}$. The device on the experimental site produces a voltage of 16 V and provides a current of about 0.12 A which can power a 2 W lamp. This performance of the prototype made on a small scale is a reliable indicator of the optimal use of this technology in the national hydraulic network of Benin to supply populations with electrical energy.
Theoretical Study on 10C Elastic Scattering Cross Sections Using Different Cluster Density Distributions and Different Potentials
Authors: Olorunfunmi Sunday , Bahini Armand , Olatinwo Adenike
Published: May 2023

Elastic scattering cross sections are a fundamental aspect of nuclear physics research, and studying the cross sections of various nuclei can provide important insights into the behavior of nuclei. In this study, the elastic scattering cross sections of 10C projectile by 27Al, 58Ni, and 208Pb target nuclei are analyzed. The aim of this study is to investigate the cluster structure of 10C and the sensitivity of the elastic scattering cross sections to different potentials. To achieve this objective, the double folding optical model and a simple cluster approach are used to analyze the cross sections. The real part of the optical potential is obtained by folding two different effective interactions, Michigan-3-Yukawa (M3Y) and JeukenneLejeune-Mahaux (JLM), with four different cluster density distributions of the 10C nucleus: 6Be + \alpha, 9B + p, 8Be + p + p, and \alpha + \alpha + p + p. The imaginary part is taken to be a Woods-Saxon phenomenological form. The sensitivity of the elastic scattering cross sections to different potentials is assessed by comparing the results obtained using different potentials. The cluster structure of 10C is validated by comparing the theoretical results with experimental data. The results show that the cross sections are sensitive to the choice of potential used and that the cluster structure of 10C is validated. The theoretical results show reasonable agreement with the experimental data.

Pre-functions are functions that possess a sequence $\{f_{n}(z,\beta)\}$ which tends to one of the elementary functions as $n$ tends to infinity and $\beta$ tends to 0. The main objective of this paper is to broaden the scope of pre-functions from functions of a real variable to functions of a complex variable by introducing pre-functions of a complex variable. We have analyzed the pre-functions of a complex variable for their properties. The pre-Laguerre, pre-Bessel and pre-Legendre polynomials of a complex variable have been obtained as special cases. Graphs have been used to visualize complex pre-functions.

Epistemological knots for a history of the resistances of Southern feminisms
Authors: Guerra Pérez Mariana , Alvarado Mariana
Published: May 2023

Este texto se sitúa en la juntura de los feminismos del sur que señalaron el encubrimiento de la heterogeneidad de las mujeres indo-afro-latino-americanas. Desde las cadencias y los ritmos de las voces de mujeres de Nuestra América cuyos saberes interrumpen, disrumpen e intervienen muestra que los problemas del feminismo blanco burgués del norte no son los de todas las mujeres puesto que algunas mujeres escapan a la fragilidad femenina que justifica el paternalismo y los micromachismos dentro y fuera de la academia, incluso dentro y fuera de la misma clase, etnia o generación. Desde los feminismos del sur se propone habilitar un diálogo entre/con “las otras” de nosotras no sólo para articular teóricamente y coalicionar políticamente nudos epistémicos que pongan en crisis el modelo de la representación y con ello una revisión del punto de vista, sino también para desmontar, paralelamente desde la ontología relacional que suponen, el privilegio epistemológico, la violencia epistémica y el extractivisimo académico que ubica y posiciona a unas sobre otras en la reproducción de “las otras de nosotras”. A partir de los posicionamientos de María Lugones, Rita Segato, Aura Cumes, Lorena Cabnal y Julieta Paredes, se propone visibilizar los nudos epistemológicos venidos de los feminismos comunitarios e indígenas que habilitan ampliaciones metodológicas desde las que podrían configurarse una historia de las resistencias de las mujeres de Latinoamérica en la exterioridad de los paradigmas euronortecentrados.

Published: May 2023

Natural products and their structural analogues have historically made a major contribution to pharmacotherapy, especially for cancer and infectious diseases. Nevertheless, natural products also present challenges for drug discovery, such as technical barriers to screening, isolation, characterization and optimization, which contributed to a decline in their pursuit by the pharmaceutical industry from the 1990s onwards. In recent years, several technological and scientific developments including improved analytical tools, genome mining and engineering strategies, and microbial culturing advances are addressing such challenges and opening up new opportunities. Consequently, interest in natural products as drug leads is being revitalized, particularly for tackling antimicrobial resistance. Here, we summarize recent technological developments that are enabling natural product-based drug discovery, highlight selected applications and discuss key opportunities.The first total synthesis and development of a variety of bioactive natural products have been accomplished by using carbohydrates as a chiral source. In addition, practically useful intermediates have been created, analogs of natural products have been prepared, their structure-activity relationships studied, and the large-scale preparations of medicinally useful compounds established.

In this article, the interrelationship between various systems for defining the Goryeo royal family and socio-cultural characteristics of the Goryeo dynasty is examined. The Goryeo royal family members had official titles related to their palace names where they lived and which reflected the blood ties or marriage relationships among royal family members right after the founding of that country. This initial system was replaced by the Chinese investiture system but in a process of replacement many creative transformations were involved.
The constitution and operating way of the royal family investiture system in the early and middle periods of the Goryeo dynasty were far from those in T’ang and Song dynasty. That’s because Chinese clan rules system based on patrilineal descent society was not efficient in the Goryeo society, and, furthermore, its royal family members were regulated by systematic endogamy. In the Goryeo dynasty, not only sons and grandsons but also daughters and granddaughters of the king were involved in the royal family investiture system. The title of Count (伯) was bestowed upon spouses of princesses. Grandsons and spouses of granddaughters of the king were invested with Sado (司徒) and Sagong (司空). Royal family members whose sons or daughters were married with king or married with king’s children were also invested with royal titles like Duke (公) and Marquis (侯).
Structure of kinship and marriage of the royal family in the early and middle periods of the Goryeo dynasty was similar to primary and secondary relatives, which were concepts commonly used in the field of anthropology, and this structure reflected the cognatic descent system in the Goryeo society. The Goryeo royal family members, also called Jewang (諸王), possessed plural statuses of kindred in this structure because of systematic endogamy amongst royal family members. It was meaningless to mention each title and each qualification one by one as T’ang and Song did because in the Goryeo dynasty king’s cousin could be his father-in-law, brother-in-law, or son-in-law.

To investigate the Effect of adding different concentrations of green tea extract as an antioxidant on specific physical semen characteristics of German Shepherd dogs during various steps of frozen semen processing this study was carried out. A total (of 20) good Ejaculate semen samples were collected in a plastic bag from German Shepherd dogs aged 3-4 yearsIn different locations (dog breeding).To achieve the current study's main objectives, two experiments were designed through periods extended from the beginning of December 2021 until the end of May 2022. The investigations included studying the physical properties of raw Semen (ejaculate volume, semen color, consistency, motility percentage, progressive motility percentage, dead sperm percentage, sperm abnormalities percentage, and hypo-osmotic swelling test (HOST). After that, semen samples were diluted with Tris supplemented with antioxidants. The physical properties of Semen were followed after cooling and after freezing (post-thawing). In the experiment, ten ejaculates were collected. Dilution of Semen was performed with Tris supplemented with two T1, T2, and T3) were cooled slowly up to 5C and equilibrated, packed into 0.5 ml straws, and put in vapor nitrogen (-196C) for 5-10  minutes after that, stored for 48and 72 hr in liquid Nitrogen (-196C). Progressive motility percentage, dead sperm percentage, sperm abnormalities percentage, and hypo-osmotic swelling test (HOST) were evaluated after cooling and post-thawing (Submerging the straws in the water bath at 37C for 30 seconds). It can be concluded from the present study that adding green tea extract as an antioxidant to the semen extender improves the ability to freeze, especially in the treatment T3 (0.01 mg/5 ml) and the T2 (0.05 mg/5 ml). This additive can decrease the negative Effect of freezing in liquid Nitrogen compared to the control group.

Bu makalede bellek çalışmalarının önemli kavramlarından biri olan “bağışlama” kavramı ele alınmış ve geçmişin iki ayrı döneminde ve iki ayrı ülkede mağdur edilmiş Eva Mozes Kor ile Hilmi Köksal Alişanoğlu’nun bağışlama deneyimleri anlaşılıp açıklanmaya çalışılmıştır. Nazilerin Yahudi soykırımı başta olmak üzere İkinci Dünya Savaşı süresince işlediği suçların mevcut yasa gereğince 8 Mayıs 1965’ten itibaren zamanaşımına uğrayacağının açıklanmasının ardından “kötülük”, “zamanaşımı”, “insanlığa karşı işlenen suçlar” gibi konuların yanı sıra “bağışlama” konusu da tartışmaya açılmıştır. Bu tarihten itibaren günümüze kadar “bağışlama” üzerine söz söylemiş filozofların görüşlerinin ışığında soykırım mağduru Eva Mozes Kor’un bağışlama deneyimi ve 12 Eylül askeri darbesi mağduru Hilmi Köksal Alişanoğlu’nun tek bir şartla unutmaya hazır oluşu incelenmiştir. Mağduriyete içkin olan acının bir duygu oluşu gibi bağışlamanın da öncelikle bir duygu olduğu ve ancak hatırlama politikasının hâkim olması koşulu ile olanaklı olabileceği görüşü savunulmuştur.

The optimal control problem is defined as a problem in determining the control u(t) that depends on time t, such that it produces the optimum value for the objective function. The optimal control system with constrained conditions can be changed to an optimal control system without constraints by constructing the value of u(t) so that u(t) is not constrained. In this research, we will examine how to determine an optimal control of a system of time-independent state space or Linear Time Invariant (LTI) with constrained states and minimize a given objective function. In addition, how to construct an optimal controller that is constrained to become an optimal controller without constraints using the penalty function method and its implementation using Matlab. The results of this study are that the optimal control is:.
Impact of the AFCFTA on Tax Revenue in Togo

The aim of this study is to examine the impact of the AfCFTA on Togolese tax revenue. The schematic facts and the gravity model applied to data from 51 countries including 41 African countries and 10 non-member countries of the AfCFTA confirm our hypothesis that the AfCFTA positively inf luences imports and exports of goods and services and generates short-term negative effects in the form of loss of tax revenue (customs duties). Thus, the schematic facts show that Togo’s imports of goods and services from African countries increased from 159.76 billion CFA francs in 2019 to 199.71 billion CFA francs in 2021, an increase of 25%. They also show that over the period 2019 to 2021, the customs duties collected amounted to an average of 54.09 billion CFA francs. This study estimates that if AfCFTA legislation had been in force since 2019, Togo would have lost an amount of around 54 billion CFA francs in customs duties. The gravity model estimates also show that AfCFTA would lead to an increase in trade between Togo and its partners and, in turn, an increase in domestic tax revenue of 2.809% and 3.532% respectively. These results urge public decision-makers to promote Togo’s specialisation in the production of goods and services for which it has a comparative advantage. This strategy will enable Togo to produce more goods and services at lower costs in order to sell them within AfCFTA and reduce unemployment.
