|---|---|
| THE COURSE AIMS TO PROVIDE STUDENTS WITH THE MASTER DEGREE IN MANAGEMENT ENGINEERING THE FUNDAMENTAL ELEMENTS FOR THE ANALYSIS IN OPERATION OF INDUSTRIAL MACHINES. THE COURSE AIMS TO POINT OUT THE ATTENTION ON THE CHARACTERIZATION OF THE DYNAMIC BEHAVIOR OF MACHINES AND PLANTS FOR DIAGNOSTICS. KNOWLEDGE AND UNDERSTANDING TO DETERMINE A MATHEMATICAL MODEL OF A MECHANICAL SYSTEM AND ITS SUBPARTS, CONSIDERING WHETHER TO ADOPT SIMPLIFYING ASSUMPTIONS AND AFFINITY. APPLYING KNOWLEDGE AND UNDERSTANDING KNOWING HOW TO SELECT THE MOST APPROPRIATE DIAGNOSTIC METHOD FOR THE SPECIFIC APPLICATION. MAKING JUDGMENTS (MAKING JUDGMENTS) UNDERSTAND THE WORKING PRINCIPLE OF MECHANICAL SYSTEMS IN SIMPLE OR INTEGRATED CONTEXTS. COMMUNICATION SKILLS (COMMUNICATION SKILLS) KNOWING HOW TO WORK IN TEAMS AND TO PRESENT THE RESULTS OBTAINED. ABILITY TO LEARN (LEARNING SKILLS) KNOWING HOW TO APPLY THE KNOWLEDGE TO DIFFERENT CONTEXTS. |
