Objectives
EXPECTED LEARNING OUTCOMES AND COMPETENCE TO BE ACQUIRED:
KNOWLEDGE OF THE APPROPRIATE TOOLS FOR THE REPRESENTATION, INTERPRETATION AND PROCESSING OF DATA FROM MEASUREMENTS AND EXPERIMENTS IN PHYSICS AND ENGINEERING.
KNOWLEDGE OF THE BASIC ELEMENTS OF PHYSICAL AND APPLIED ACOUSTICS.
ABILITY TO ANALYZE AND SYNTHESIZE IN HANDLING DATA IN ENGINEERING PROBLEMS.
KNOWLEDGE AND UNDERSTANDING SKILLS:
UNDERSTANDING OF THE TERMINOLOGY USED IN THE ANALYSIS OF PHYSICAL DATA, METHODS OF ANALYSIS OF EXPERIMENTAL DATA AND RELATED STATISTICAL TECHNIQUES. ACQUISITION OF METHODOLOGIES FOR THE STUDY OF PROBLEMS OF ENGINEERING, AND THE FUNDAMENTAL CONCEPTS OF THE ANALYSIS OF ACOUSTIC AND WAVE SIGNALS.
ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
TO BE ABLE TO MANAGE A SAMPLE OF EXPERIMENTAL DATA BY DETERMINING ITS STATISTICAL PROPERTIES AND VERIFYING ITS PREDICTIVE CAPACITY. TO ACQUIRE THE BASIC CONCEPTS NECESSARY FOR THE REALIZATION OF AN EXPERIMENTAL MEASUREMENT AND ITS UNDERSTANDING IN ACOUSTICS AND IN OTHER FIELDS.
AUTONOMY OF JUDGMENT:
TO BE ABLE TO UNDERSTAND WHAT IS THE MOST APPROPRIATE SCHEME FOR THE ANALYSIS OF A SAMPLE OF EXPERIMENTAL DATA AND FOR DEALING WITH A PROBLEM IN ACOUSTICS. TO BE ABLE TO DETERMINE THE CONDITIONS NECESSARY FOR THE IMPLEMENTATION OF A PHYSICAL MEASURE IN THE ENGINEERING FIELDS.
COMMUNICATION SKILLS:
KNOW HOW TO WORK IN A TEAM AND ORALLY PRESENT A TOPIC RELATED TO THE ANALYSIS OF PHYSICAL DATA AND TO ACOUSTICS.
ABILITY TO LEARN:
TO BE ABLE TO APPLY THE ACQUIRED KNOWLEDGE TO THE CONTENTS OF THE COURSE, AS WELL AS IN DIFFERENT CONTEXT, BY MEANS OF INDIVIDUAL AND AUTONOMOUS DEEPENING OF THE SUBJECT, UNDER THE SUPERVISION OF THE TEACHER.
Prerequisites
FOR A SUCCESSFUL CLASS, IT IS REQUIRED TO KNOW THE BASIC PHYSICS, WITH PARTICULAR REFERENCE TO MECHANICAL AND ELECTROMAGNETIC CONCEPTS, IN RELATION TO PHYSICS, PHYSICS I AND PHYSICS II COURSES.
Contents
PRESENTATION AND ANALYSIS OF EXPERIMENTAL DATA (10 HOURS OF THEORY AND 5 HOURS OF EXERCISES):
EXPERIMENTAL DATA PRESENTATION. INTRODUCTION TO DESCRIPTIVE STATISTICS AND ERROR THEORY. STATISTIC MEASUREMENTS RESULTS. DISTRIBUTION OF BERNOULLI, POISSON AND GAUSS. EXPLORATORY DATA ANALYSIS. INFERENCE AND COMPARISON. CHI SQUARE TEST.
PHYSIC METHODS FOR SOLVING ENGINEERING PROBLEMS AND PREDICTIVE MODELS FOR PHYSICAL OBSERVABLES (10 HOURS OF THEORY AND 5 HOURS OF EXERCISES):
PHYSIC METHODS COMPARISON. TIME SERIES ANALYSIS. POISSON PROCESSES. MICRO AND MACRO MODELLING OF PHYSICAL AND ENGINEERING PHENOMENA.
WAVE PHYSICS, ACOUSTICS AND APPLICATIONS TO ENGINEERING (18 HOURS OF THEORY AND 12 HOURS OF EXERCISES):
ACOUSTIC AND MECHANICAL WAVES. FOURIER ANALYSIS. FREQUENCY SPECTRUM. SOUND PRESSURE LEVEL, INTENSITY LEVEL AND SOURCE POWER LEVEL. DECIBEL SCALE AND LEVELS COMPOSITION. SOUND CONTINUOUS EQUIVALENT LEVEL AND SOUND EXPOSURE LEVEL (SEL). PERCENTILE LEVELS. ENVIRONMENTAL ACOUSTICS AND NOISE CONTROL: LEGISLATION AND TECHNICAL ISSUES. ROOM ACOUSTICS AND QUALITY OF INDOOR ENVIRONMENTS. BUILDING ACOUSTICS. NON-DESTRUCTIVE STRUCTURAL HEALTH MONITORING TECHNIQUES BASED ON ACOUSTIC PRINCIPLES.
Teaching Methods
THE CLASS INCLUDE THEORETICAL (ABOUT 36 HOURS), EXERCISE LESSONS (ABOUT 16 HOURS) AND LABORATORY LECTURES (ABOUT 8 HOURS). DURING EXERCISES AND LAB, A TOPIC TO BE ANALYZED IS ASSIGNED TO THE STUDENTS, UNDER THE SUPERVISION OF THE PROFESSOR. QUESTIONS AIMED AT THE UNDERSTANDING OF THE STUDY OF A PHYSICAL DATA SAMPLE ARE ASSIGNED, VERIFYING THE REAL ABILITY OF THE STUDENTS TO HANDLE AN EXPERIMENTAL MEASUREMENT. IN ADDITION, SIMPLE EXPERIMENTS OF ACOUSTICS WILL BE PROPOSED, TOGETHER WITH SIMULATION OF SOUND MEASUREMENTS, FULFILLING THE REGULATIONS IN FORCE. MOREOVER, BOTH FOR THE MODELLING AND ANALYSIS STUDY AND FOR ACOUSTICS, PROBLEMS ARE ASSIGNED, IN ORDER TO IMPROVE THE THINKING AND INVESTIGATION SCHEMES OF STUDENTS INVOLVED.
THE CLASS ATTENDANCE IS MANDATORY. THE MINIMUM PERCENTAGE OF PRESENCES IS 70%.
Verification of learning
THE EVALUATION OF CLASS AIMS ACHIEVEMENT IS DONE BY MEANS OF WRITTEN AND ORAL EXAMINATION. THE TIME DURATION OF THE TESTS CAN VARY FROM 2 TO 3 HOURS, ACCORDING TO THE TYPOLOGY OF PROBLEMS AND QUESTIONS. THE CRITERIA ARE FOCUSED ON THE ABILITY OF THE STUDENT TO SOLVE PROBLEMS AND TO DESCRIBE PHYSICAL PHENOMENA RELATED TO CLASSICAL PHYSICS. IN THE WRITTEN EXAM, THE STUDENT IS ASKED TO SOLVE PROBLEMS RELATED TO THE APPLICATION OF FUNDAMENTAL CONCEPTS OF THE CLASS. THE CONSTANT AND SUCCESSFUL PARTICIPATION TO THE ACTIVITIES AND EXERCISES ASSIGNED DURING THE CLASS COULD ALLOW THE STUDENT TO SKIP THE WRITTEN EXAM AND GO DIRECTLY TO THE ORAL EXAM. THE ORAL EXAM FOCUSES ON THE CHECK OF THE SUCCESSFUL LEARNING OF THEORETICAL AND APPLICATIVE ELEMENTS PRESENTED DURING THE CLASS, JUDGING IN PARTICULAR THE CONTENTS, THE ACCURACY OF THE ORAL PRESENTATION, THE VERBAL AND MATHEMATICAL EXPOSITION, THE ABILITY OF CORRELATING DIFFERENT TOPICS OF THE PROGRAM. THE FINAL MARK IS GIVEN IN POINTS WITH A MAXIMUM OF 30, INCLUDING THE RESULTS OF THE WRITTEN AND ORAL TESTS.
THE RESULT “CUM LAUDE” IS OBTAINED CONSIDERING:
-CLARITY OF EXPOSITION IN TERMS OF PROPER SCIENTIFIC LANGUAGE,
-ABILITY TO CORRELATE DIFFERENT TOPICS OF THE CLASS, AND, IF POSSIBLE, TOPICS INCLUDED IN OTHER DISCIPLINES,
-INDEPENDENCE OF JUDGEMENT.
