Some of them happen in a thousandth of a second, while others happen in minutes, hours, days, months and years. It is also known that such reactions can occur quickly and slowly, depending on the conditions, for example, they can be rapid at high temperatures and slow at cold temperatures. The difference between the rates of these reactions can be large. The following article is devoted to the study of the effect of temperature on the rate of chemical reactions.</p> Omonova Maxfuza Sodiqovna Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-10 2022-05-10 8 1 3 Main Requirements of the O'zDSt ISO\IEC Standard 17021:2009 https://zienjournals.com/index.php/tjet/article/view/1530 <p>On September 15, 2006, ISO/IEC 17021:2006 Conformity assessment -Requirements for bodies providing audit and certification of management systems In December, on the eve of 2007, the International Accreditation Forum (IAF) and the International Organization for Standardization (ISO) issued a joint communiqué establishing a global two-year transition period for meeting its requirements until September 15, 2008.</p> Kamolova Muxlisa Khudoyberdiyevna Soliev Muzaffar Furkat o`g`li Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-10 2022-05-10 8 4 9 Recommendations for the Effective Operation of MercedesBenz Bus Air Filters in Hot Climatic Conditions https://zienjournals.com/index.php/tjet/article/view/1563 <p>This article is devoted to the regeneration of air filters Mercedes-Benz buses, justified the number of optimal regeneration of clogged air filters.

Online sequential extreme learning machine is a method of online learning solving the problem of observing data of different sizes. However, the input weights and OSELM hidden layer biases are randomly determined. This results in an incorrect classification result. In the proposed method, the data are classified using anonline sequential extreme learning machine algorithm. Certainsoftware based on artificial bee colony algorithm (ABC -OSELM) was developed to select the parameters of the sequential fast online machine learning algorithm. The simulation results show that the proposed method has achieved a 7% improvement in accuracy criteria compared to the base paper.</p> Dhulfiqar Mahmood Tawfeeq Al-Saada Maryam Thabet Hussein Al-Khazraji Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-11 2022-05-11 8 20 29 Issues With the Use of Solar Dryers https://zienjournals.com/index.php/tjet/article/view/1589 <p>This article discusses the issues of identifying and classifying the most efficient options for a solar dryer, the study and analysis of different types of solar dryer appearances and performance processes.</p> Ramazonova Fotima Yorboyevnа Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-13 2022-05-13 8 30 32 Model and Chattering Free Adaptive Fuzzy SMC for Robotic Manipulator Systems https://zienjournals.com/index.php/tjet/article/view/1590 <p>This In recent decades, many researchers proposed fuzzy Sliding Mode Control (SMC) strategies that aim to eliminate the chattering problem in control of Multi-Input-Multi-Output (MIMO) nonlinear robotics manipulator systems. All these methods impose the need to determine the dynamic model of system under control, which is a challenging task in many practical cases. This paper presents a new model free and chattering free SMC method for MIMO nonlinear robotics manipulator systems based on Proportional-Derivative (PD) and fuzzy logic control. Proposed controller combines the robustness feature of SMC, simplicity of Proportional-Integral-Derivative (PID) control and ability of fuzzy technique in function approximation of discontinuity part of traditional SMC. In this paper, PD control is used as equivalent control in order to stabilize the system while adaptive fuzzy SMC is used to handle uncertainty of the system. Lyapunov’s second method is utilised to prove stability of proposed controller. Two different robotic manipulator configurations; two-links with payload and three links robotic manipulator under external disturbance and system uncertainties are simulated to demonstrate the efficiency of the proposed method.</p> Maryam Sadeq Ahmed Ali Hussien Mary Hisham Hassan Jasim Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-13 2022-05-13 8 33 43 Time Series Analysis of Household Energy Using Recurrent Neural Network https://zienjournals.com/index.php/tjet/article/view/1591 <p>In this paper we create and compare two time series machine learning model based on recurrent neural network to analyze future energy consumption in a particular location.

However, even an experienced network technician will find it difficult to monitor all relevant service network time series at the same time. The approach is to incorporate a mathematical model into the monitoring application that can automatically detect deviations in the time series. And when we talk about the growing number of models, the choice is difficult, because the chosen model must be compatible with real-time monitoring, in this paper we adopt a new approach which is to integrate the theory of exponential smoothing and intelligent properties in Holt Winters algorithm by using RRDtool as a tool for data collection and representation With real-time schemes, although this technique is not perfect, it is adaptable, effective and successful as a tool for automatic identification of deviant behavior after being trained to identify anomalies through prediction based on past and future steps.</p> Alaa Abdulhussein Daleh Al-magsoosi Copyright (c) 2022 https://creativecommons.org/licenses/by-nc/4.0 2022-05-20 2022-05-20 8 84 93 Use of hydropower plants and its main problems https://zienjournals.com/index.php/tjet/article/view/1710 <p>The use of hydro resources in the article.
