[03642] XAI Based Fault Diagnosis for Steel Plates Manufacturing
Author(s) :
Athar Kharal (Center for Advanced Studies in Pure and Applied Mathematics (CASPAM), Bahuddin Zakariya University, Multan)
Abstract : This work uses Explainable Artificial Intelligence tools to develop a fault diagnosis classifier for steel plates. By incorporating insights from techniques such as Ceteris Paribus, Partial Dependence and Breakdown profiles, IF-THEN rules, and an optimized Random Forest and Association Rule Mining, the methodology sought to achieve a high performance using a single ensemble classifier. The methodology is based on medoids and SMOTE and provides valuable insights for experts in the steel manufacturing industry.

Abstract : Consideration of the observabilities of linear hybrid descriptor systems implies the distinguishability of these systems to be imperative. We have obtained some results related to the distinguishability of the descriptor systems. Also, we have attained equivalent criteria for input distinguishability of descriptor systems with a regular pencil.

Abstract : Fuel injector nozzle geometry affect the diesel engine spray and combustion characteristics. This paper explores the effects of nozzle geometry parameters, wall roughness parameters and pressure difference on swirl number, mass flow rate, turbulent kinetic energy and vapor volume fraction. Large-eddy simulations and k-𝜔 SST Transient models are used to validate the modelling approach. Response Surface Method and Design of Experiment are used to optimize swirl number, turbulent kinetic energy and their linear combination.
[04696] In-Cylinder Combustion Investigation Against Some Injection Characteristics

Abstract : This study investigates the impact of fuel injection timing and spray angle on combustion characteristics of a heavy-duty diesel engine. CFD simulations are carried out by employing appropriate models to represent different physical and chemical processes. These parameters have significant role in engine design for enhanced combustion efficiency and engine performance. Late injection results into relatively smooth burning rates and considerably lower temperature and pressure peaks without significantly compromising the combustion quality and engine power.

Abstract : We consider the design of an intelligent, efficient, optimal, robust and hybrid control system based on the adaptive neuro-fuzzy inference system and PID controllers. The system will control air, fuel and EGR for optimal performance and minimum emissions. The system design may involve deep learning of recurrent neural network having several hidden layers with LSTM layer to make the system efficient and more accurate. Optimal control may be incorporated using quadratic programming / genetic algorithm.

Abstract : The air flow in engine plenum is complex due to multidimensionality and transient nature of engine operation. This study describes the design modification of intake plenum geometry of a V12 diesel engine and analyses the effects on flow parameters. The original design was found to have strict limits, making it difficult to enhance engine efficiency. However, the modified design is more energy efficient, with greater volumetric efficiency, increased mass flow rate, and turbulent kinetic energy.

Abstract : This study numerically investigates Homogeneous Charge Compression Ignition (HCCI) combustion in a heavy duty engine operating at 4 MPa boosted intake pressure. Effect of variations in charge composition and temperature on combustion performance parameters such as indicated mean effective pressure, indicated torque, indicated power, indicated specific fuel consumption and fuel efficiency are analyzed. Maximum fuel efficiency (~ 47%) is obtained for equivalence ratios between 0.09 − 0.2 for initial temperatures 350 K and 400 K.
