Authors:   Bauman Moscow State Technical University, Mazaishvili Evgenii K. , Tassov Kirill L. ,   Bauman Moscow State Technical University
Published: January 2023

The paper presents a method of using a neural network for clustering objects flying against the sky background. Such a method is proposed to be used for the tasks of the detection or assignment to a certain cluster, as well as for quickly determining the danger of an object flying through monitoring zone. To solve this problem, a neural network is used, consisting of a convolutional network (determining the static features of an object, for example, shape and color) combined with a recurrent network (determining the dynamic features of an object, for example, the movement of propeller blades, flapping wings), the results of which are fed to the Kohonen map, where the clustering of the object occurs. Examples of input and output data of the method are shown, as well as ways to interpret the output data (Kohonen map) to quickly determine the danger of a flying object. Methods for preliminary processing of input data are given. The article also outlines the basics for the architecture of recurrent and convolutional neural networks used in the presented method. A training algorithm and a set of data used in neural network training are described. Studies have been carried out and the results of the method are presented. An estimate of the effectiveness of the method for video analytics of flying objects taken from a video stream is given.

RENDENDO-SE AO BILRO: A RESSIGNIFICAÇÃO CONTEMPORÂNEA DO LUXO EM PRODUTOS ARTESANAIS SUSTENTÁVEIS
Authors: Machado Jamilly , Novelli Daniela , Schulte Neide Kohler
Published: January 2023

Diante da emergência contemporânea de um novo mercado de luxo, pautado em valores simbólicos, culturais e experienciais, sem abrir mão da exclusividade, percebe-se uma crescente procura por produtos sustentáveis. Produtos artesanais feitos à mão se encaixam nos dois fenômenos – luxo e sustentabilidade, pois possuem atributos de exclusividade, valor simbólico e cultural, bem como empregam o processo slow de fabricação e mão-de-obra local. Nesse sentido, a renda de Bilro catarinense foi escolhida como objeto de estudo de uma pesquisa básica, qualitativa, de objetivo descritivo e exploratório de conceitos teóricos, na qual pretendeu-se demonstrar o enquadramento desta renda na categoria de “produto de luxo sustentável”, propondo assim uma ressignificação de conceitos. Os resultados apontaram que a renda de bilro apresenta parâmetros que se enquadram tanto na produção baseada no slow fashion quanto no rol de novas mercadorias de luxo do século XXI, instigando a pensar principalmente na união produtiva, criativa e inovadora entre designers de moda e artesãos locais, na valorização por parte das marcas pelo trabalho manual bem pago com lucros bem distribuídos aos artesãos e nas novas escolhas guiadas pelo consumo emocional.

Authors: Soares Kálita Louhanny Gomes
Published: January 2023

Análises relacionadas à capacidade adaptativa dos territórios demonstram que, em geral, as cidades dos países em desenvolvimento não estão preparadas para lidar com as consequências das mudanças climáticas. O déficit de uma infraestrutura verde robusta e integrada aos demais sistemas urbanos é uma realidade e impacta diretamente na qualidade de vida local. Estudos aplicados em Belo Horizonte, MG, evidenciaram as regiões mais vulneráveis às mudanças do clima, seja por sua exposição mais elevada aos impactos, seja por sua baixa capacidade de absorvê-los. Este trabalho propõe a aplicação de ferramentas e metodologia balizada em normativas da Prefeitura Municipal para mapear, no território do Confisco, na regional Pampulha, locais aptos ao plantio de indivíduos arbóreos. Os resultados demonstraram o potencial de adensamento local da vegetação. Essa possibilidade atesta capacidade adaptativa do território que poderia ser ampliada com esse adensamento, contribuindo na redução da sua vulnerabilidade climática.

Published: January 2023

Indonesia telah mengalami perkembangan ilmu pengetahuan dan teknologi yang cukup pesat pada abad ke-20 yang dikenal juga dengan era Revolusi industri 4.0. Pesatnya perubahan dan perkembangan teknologi di era 4.0 ini tentunya merubah tatanan dunia yang dimana bukan hanya dari segi positif saja melainkan juga terdapat dampak negatif yang menyertai. Keadaan negatif tersebut salah satunya berupa degradasi karakter yang dialami oleh kebanyakan kaum remaja hingga anak-anak. Oleh karena itu penumbuhkembangan karakter pada anak sangat penting, salah satunya yaitu karakter kemandirian. Penelitian ini bertujuan untuk mengetahui dan mendeskripsikan peran pondok pesantren dalam menumbuhkembangkan karakter kemandirian santri di era 4.0 beserta faktor pendukung dan penghambatnya. Kemudian untuk metode penelitian yang digunakan yaitu dengan pendekatan kualitatif dan jenis studi kasus. Penelitian ini menggunakan teknik pengumpulan data wawancara, observasi, dan dokumentasi. Berdasarkan deskripsi data hasil penelitian menunjukan bahwa upaya yang dilakukan Pondok Pesantren Nurul Hakim Kediri Lombok Barat dalam menumbuhkembangkan karakter kemandirian santri di era 4.0 dimulai dari proses tes kepondokan sebelum menjadi santri. Upaya tersebut dilakukan dengan beberapa metode yang efektif yaitu pembiasaaan, keteladanan, dan pendekatan spiritual. Faktor pendukung upaya penumbuhkembangan karakter kemandirian santri tersebut salah satunya yaitu lingkungan yang kondusif dan nyaman serta dukungan dari walisantri. Faktor pendukung lainnya yaitu melalui kegiatan-kegiatan kepondokan yang sifatnya membangun atau menumbuhkembangkan karakter kemandirian santri, misalnya kegiatan pramuka, muhadasah, muhadaroh, dan kegiatan pembersihan setiap pagi dan sebelum tidur. Selain faktor pendukung tentu juga terdapat faktor yang menjadi penghambat penumbuhkembangan karakter kemandirian santri yaitu peran orangtua atau walisantri. Selain menjadi faktor pendukung peran walisantri juga bisa menjadi penghambat dalam proses penumbuhkembangan karakter kemandirian santri karena terlalu memanjakan anak-anak mereka dan tidak mempercayai pondok sepenuhnya untuk mendidik anak-anak menjadi pribadi yang mandiri.

The Water Area of Sawa Lake as Derived from Land Surface Temperature and Remote Sensing Data
Authors: Radeef Haidar A. , Abdulameer Inbethaq M-Ali
Published: January 2023

Sawa Lake is one of the unique lakes in Iraq. It is located in the southwestern part of Iraq. It is one of the closed lakes, as no surface water source works to feed the lake. The lake feeds on groundwater. The source of this groundwater is the Dammam Basin. During the past ten years, The lake has had many changes, which led to a decrease in water levels. This also led attention to study of the causes of these changes. Many types of research were presented in the study of the state of the lake. This research used remote sensing images from Landsat 8 OLI to monitor the changes during 2020-2021 by applying the NDWI equation to extract water area from image data. The results of the areas were obtained from a special report by Normalized Difference Water Index (NDWI). Then, the lake surface water temperature was derived from Landsat 8 thermal bands (TIRS). The lake water area and temperatures increased in summer and decreased in winter and autumn. Then, it is not the main reason for the change in the lake water area. The levels of the lake water rise during the dry period and decrease during the rainy period. The natural factors have little influence in reducing the lake water. It is attributed to human factors, groundwater depletion, and a reduction in water supply from the Dammam Basin, which feeds the lake.
Exponentially Fitted Diagonally Implicit EDITRK Method for Solving ODEs
Authors: Fawzi Firas A. , Jaleel Nour W.
Published: January 2023

This paper derives the EDITRK4 technique, which is an exponentially fitted diagonally implicit RK method for solving ODEs . This approach is intended to integrate exactly initial value problems (IVPs), their solutions consist of linear combinations of the group functions  and  for exponentially fitting  problems, with  being the problem’s major frequency utilized to improve the precision of the method. The modified  method EDITRK4 is a new three-stage fourth-order exponentially-fitted diagonally implicit approach for solving IVPs with functions that are exponential as solutions. Different forms of -order ODEs must be derived using the modified system, and when the same issue is reduced to a  framework of equations that can be solved using conventional RK approaches, numerical comparisons must be done. The findings show that the novel approach is more efficacious than previously published methods.

Published: January 2023

The use of bio-fruit waste has more attention in recent years because of the low cost of bio-fibers and the protection of the environment. In this study, the epoxy was reinforced with fruit residues (cantaloupe peel powder) in proportions (1%, 2%, 3%, 4%, 5%, 7.5%, and 10% by weight) as results of mechanical tests such as impact, hardness, flexural and compression.
Adding sub microns particle size cantaloupe peels particles with a weight ratio of 7.5% improves the epoxy mechanical properties, like impact strength, hardness, flexural strength, and compression strength by 59.43%, 5.8%, 45.7%, and 118.2%, respectively.
Using X-ray diffraction, the crystallite size ( D) of cantaloupe peel the powder was about (3 nm).
In this research, Scanning electron microscopy was used to examine the morphology of the (epoxy/7.5 % cantaloupe peel powder) composite and to interpret the improvement in epoxy mechanical properties.
Improved Runge-Kutta Method for Oscillatory Problem Solution Using Trigonometric Fitting Approach
Authors: Hussain Kasim A. , Hasan Waleed J.
Published: January 2023

This paper provides a four-stage Trigonometrically Fitted Improved Runge-Kutta (TFIRK4) method of four orders to solve oscillatory problems, which contains an oscillatory character in the solutions. Compared to the traditional Runge-Kutta method, the Improved Runge-Kutta (IRK) method is a natural two-step method requiring fewer steps. The suggested method extends the fourth-order Improved Runge-Kutta (IRK4) method with trigonometric calculations. This approach is intended to integrate problems with particular initial value problems (IVPs) using the set functions  and   for trigonometrically fitted. To improve the method's accuracy, the problem primary frequency  is used. The novel method is more accurate than the conventional Runge-Kutta method and IRK4. Several test problems for the system of first-order ordinary differential equations carry out numerically to demonstrate the effectiveness of this approach. The computational studies show that the TFIRK4 approach is more efficient than the existing Runge-Kutta methods.

Published: January 2023

Csaszar introduced the concept of generalized topological space and a new open set in a generalized topological space called -preopen in 2002 and 2005, respectively. Definitions of -preinterior and -preclosuer were given. Successively, several studies have appeared to give many generalizations for an open set. The object of our paper is to give a new type of generalization of an open set in a generalized topological space called -semi-p-open set. We present the definition of this set with its equivalent. We give definitions of -semi-p-interior and -semi-p-closure of a set and discuss their properties. Also the properties of -preinterior and -preclosuer are discussed. In addition, we give a new type of continuous function in a generalized topological space as -semi-p-continuous function and -semi-p-irresolute function. The relationship between them are showen. We prove that every -open ( -preopen) set is an -semi-p-open set, but not conversely. Every -semi-p-irresolute function is an -semi-p-continuous function, but not conversely. Also we show that the union of any family of -semi-p-open sets is an -semi-p-open set, but the intersection of two -semi-p-open sets need not to be an -semi-p-open set.

The present study aimed to forecast environmental parameters that drive the change of phytoplankton community structure in the lake. The present study was carried out in Baghdad Tourist Island Lake (BTIL) for the period From October 2021 to May 2022. The study included the quality and quantity of phytoplankton, moreover, the highest and lowest value of the physical and chemical parameters were (Water temperature (13-30 °C), Light penetration (94-275cm), electric conductivity (837-1128 µS/cm), salinity (0.5-0.7 ‰), pH (7-8.2), total alkalinity (126-226 mg CaCO3/L), total Hardness (297-395 mg CaCO3/L), Calcium (62-98 mg/L), Magnesium (59-75mg/L), Sodium (45-77 mg/L), Potassium (4-9 mg/L), dissolved oxygen (6-9 mg/L), total dissolved solids (586-777 mg/L), total phosphorus (0.1-0.7 mg/L), total nitrogen (0.2-3 mg/L). Monthly samples were taken from the subsurface water from three sampling sites in the Lake and the results and presented as dry and wet seasons. A total of 127 algal taxa was identified in the dry and wet seasons with the dominancy of diatoms (Nitzschia, Gomphonema, Navicula, Ulnaria) and followed by Cyanophyceae (Oscillatoria, Merismopedia) and Chlorophyceae (Cladophora), while Dinophyceae (Ceratium, Gymnodinium), and Euglenophyceae (Euglena) were uncommon. The lowest total cell number of phytoplankton was 221cell*104 /L in the first site during the wet season, while the highest total cell number of phytoplankton was recorded at the third site with 323×104 cells/L in the dry season. The Canonical Correspondence Analysis (CCA) showed the impact of environmental parameters on phytoplankton community structure. Therefore, the changes in phytoplankton species were noticed in the present study in comparison with previous periods and this finding is a warning of alteration in the environmental condition of the lake.

Wellhead merupakan sebuah  komponen yang digunakan dalam proses pengeboran minyak dan gas. Dalam proses pemindahan wellhead dari satu tempat ke tempat lain, sering digunakan alat bantu berupa eyebolt. Penggunaan peralatan bantu pengangkatan berfungsi untuk membantu proses pengangkatan agar lebih mudah dilakukan dan lebih aman. Eyebolt merupakan sebuah pengait berulir yang berfungsi sebagai alat bantu angkat. Untuk mengetahui keamanan eyebolt saat digunakan, perlu dilakukan sebuah studi mengenai perilaku mekanis dari eyeblot tersebut. Selain itu apakah perbedaan sudut pengangkatan akan mempengaruhi besaran tegangan, regangan, peralihan, serta nilai Factor of Safety (FOS) secara signifikan. Untuk mengetahui perbandingan perbedaan sudut tersebut dilakukan simulasi pada software Solidwork dengan nilai pembebanan 575.604 N. Proses simulasi dilakukan dengan sudut 35°, 45°, 60°. Tegangan maksimum terjadi pada sudut 35° yaitu 195.765 Mpa,dan FOS paling aman pada sudut 60° yaitu 2.7, artinya semakin besar sudut pengangkatan eyebolt yang digunakan semakin aman.

Published: January 2023

Baja high strength low alloy (HSLA) memiliki kekuatan mekanis lebih tinggi dibanding baja pada umumnya tetapi dengan weldability yang mudah, dalam studi ini material yang dipakai adalah S690QL.  Flame straightening digunakan untuk mengembalikan bentuk material S690QL yang telah terdistorsi akibat proses pemanasan dan pendinginan selama proses fabrikasi. Tujuan penelitian ini adalah untuk mengetahui nilai kekerasan material S690QL setelah melalui proses flame straightening. Proses Flame straightening dilakukan dengan teknik line heating menggunakan variasi suhu 700 °C, 750 °C, dan 800 °C selama 45 menit di setiap varian suhu. Nozzle dengan diameter 14 mm – 20 mm dengan multi flame torch digunakan dalam proses flame straightening.  Sebagai langkah pengurangan tegangan sisa dan stress relieving, Post Weld Heat Treatment (PWHT) dengan holding time 1 jam dilakukan. Proses dilanjutkan dengan air cooling hingga temperatur ruang. Pengujian kekerasan Vickers dilakukan dengan pengambilan 9 sampel titik, 2 titik pada bagian base metal, dan 7 titik pada area Heat Affected Zone. Berdasarkan hasil pengujian diketahui bahwa pada suhu 700 °C dan 750 °C belum terjadi perubahan fasa, sehingga nilai kekerasan tertinggi pada suhu tersebut adalah 270 HVN dan 295 HVN. Sedangkan pada suhu 800 °C, terjadi perubahan fasa ditandai dengan nilai kekerasan yang meningkat menjadi 379 HVN.

Kualifikasi welder adalah pengkualifikasian juru las atau welder yang bertujuan untuk membuktian kualitas welder tersebut yang dilaksanakan sesuai dengan kaidah – kaidah yang ada di dalam international code/standard seperti AWS, API, ASME, ISO dan kode/standar lainnya. Tujuan dari pembuatan laporan ini adalah untuk merancang skema pengkualifikasian welder dengan menggunakan tiga kode/standar sekaligus, yaitu : AWS D1.1 (2020), ASME Sec. IX (2019) dan ISO 9609-1 (2017). Dengan demikian, dapat meminimalisasi penggunaan biaya, waktu dan juga persiapan yang dibutuhkan untuk melakukan kualifikasi welder tersebut. Metodologi yang digunakan yaitu kajian pustaka untuk mendapatkan kesamaan dari variabel-variabel yang nantinya akan digunakan untuk mengkualifikasi welder dengan menggunakan tiga kode/standar yang digunakan. Setelah mendapatkan variabel-variabel yang dibutuhkan, tahapan selanjutnya ialah implementasi variabel-variabel tersebut untuk melakukan kualifikasi welder mulai dari persiapan material, proses pengelasan hingga pengujian dari hasil lasan. Agar kualifikasi welder dengan tiga kode/standar sekaligus tersebut dapat dilakukan, perlu memperhatikan keterkaitan untuk setiap variabel yang digunakan untuk dapat meng-cover antara satu kode dengan kode yang lainnya. Hal ini disebabkan apabila salah satu variabel tidak dapat terpenuhi di salah satu kode/standar yang digunakan, maka pengkualifikasian welder menggunakan tiga kode/standar tidak dapat dilaksanakan. Material yang digunakan pada kualifikasi welder ini ialah ASTM A106 Grade B dengan panjang material 170 mm × 170 mm dengan ketebalan 18,26 mm dan diameter 6” (168,3 mm) sch 160. Metode pengujian yang digunakan ialah Visual Inspection dan Side Bend Test dengan banyaknya jumlah material yang digunakan untuk Side Bend Test ialah empat buat material uji
