Quality control systems

In this paper, we propose a system using fuzzy PID controller, STM32F103C8T6 microcontroller, ESP8266 wifi module to monitor DC motor speed and some parameters to evaluate the quality of the system through web server. System simulation on Matlab-Simulink confirms the effectiveness of this controller.

Improving driver ride comfort of a wheel loader is important to avoid potential health hazards from the whole-body vibration. A fuzzy self-tuning of PID controller is designed to control the damping coefficient of Semi-active cab isolation system (SCIS) for a wheel loader. A dynamic model of a wheel loader is establish under survey conditions for analysis and evaluation.

Ebook "Construction quality management" examines the various quality management systems applied to the construction industry in Hong Kong and other parts of the world. Hong Kong's experience is particularly important because it plays a leading role in construction quality management globally. The text traces the change from quality control (QC) practice in the 1970s and 1980s, to the quality assurance (QA) concept in the 1990s, and finally to the emerging total quality management (TQM) philosophy.

This article is devoted to the development of one of directions of optimization of the system of quality supply chain management in modern enterprise-selfassessment mechanism. In the work of organized approaches to classification by quality costs a new category "anticrisis" quality costs, allowing you to reveal the cost of the quality in the crisis of the organization. Proposed architectural mechanism for self-evaluation. The authors formulate and test hypotheses about the positive impact of the introduction of this mechanism in the system of quality supply chain management.

Phosphate enters the aquatic system through runoff from pastures, croplands, urban areas, and sewage treatment systems and fosters algal bloom causing eutrophication at higher concentrations in water. Therefore, controlling its concentration through routine water quality monitoring in aquatic ecosystems is essential.
