The coefficient of variation of the produced yarn with various components is compared with the coefficient of variation in terms of hairiness, specific breaking load, sN/tex, coefficient of variation in terms of specific breaking load, % with the indicators of yarn produced at the spinning mill and Uster.</p> Nuriddin Ruziboev Musadulla Xoliyarov Copyright (c) 2024 2024-06-05 2024-06-05 4 6 7 11 ELEKTR TA'MINOTI ISHONCHLILIGINI OSHIRISH USULLARI VA VOSITALARINI ISHLAB CHIQISH https://in-academy.uz/index.php/EJMTCS/article/view/33302 <p>Hozirgi kunda elektr ta'minoti odamlar uchun qulaylik va iqtisodiyotning turli tarmoqlarining samarali ishlashini ta'minlashda muhim rol o'ynaydi. Biroq, elektr ta'minotidagi tez-tez uzilishlar va uzilishlar ishlab chiqarish jarayonlarining to'xtashi, fuqarolar xavfsizligiga tahdid va halokatli iqtisodiy yo'qotishlar kabi jiddiy oqibatlarga olib keladi. Shu munosabat bilan elektr ta'minotining ishonchliligini oshirish usullari va vositalarini ishlab chiqish davlat va xususiy kompaniyalar uchun dolzarb vazifaga aylanmoqda. Ushbu maqolada biz asosiy muammolar va xatarlarni, ishonchliligini oshirishning mavjud usullarini, shuningdek, ushbu muammoni hal qilishga yordam beradigan yangi yondashuvlar va texnologiyalarni ko'rib chiqamiz.</p> ZINAXAN BORANBAEVA Copyright (c) 2024 2024-06-07 2024-06-07 4 6 12 15 ALGORITHMS FOR CALCULATING EXACT INTEGRALS IN C++ https://in-academy.uz/index.php/EJMTCS/article/view/33502 <p>Integrals are a fundamental concept in calculus that is used to calculate the total area under a curve or the accumulated effect of a changing quantity over a specific interval. In many scientific and engineering applications, the ability to compute integrals accurately is crucial for understanding and analyzing various phenomena. In this article, we will discuss different algorithms and methods for calculating exact integrals in C++. These algorithms are essential for numerically approximating the exact value of integrals when analytical solutions are not feasible or too complex. We will explore various numerical integration techniques, such as the Riemann sum method, the Trapezoidal rule, Simpson's rule, and adaptive quadrature methods. These algorithms provide different approaches to approximating integrals with varying levels of accuracy and computational efficiency. By understanding and implementing these algorithms in C++, developers and researchers can efficiently calculate exact integrals for a wide range of applications, from physics and engineering to finance and data analysis.</p> Gulayim Usnatdinova Copyright (c) 2024 2024-06-10 2024-06-10 4 6 16 19
