Since the images acquired are generally affected by highfrequency noise (particularly significant in the case of speckle interferometry), it has been necessary to develop special procedures for determining peak location using the minimum amount of local information.

The technique proposed, which was developed to be applied within an interface between a geometric modeler (B-rep type) and a 3-D BEM code for elastic stress analysis, can be as well applied to 2-D finite element discretization problems. At the present stage of development, the technique operates over planar domains which are externally and internally bounded by polygonal contours and may contain any number of circular holes. Boundary Elements elements). Actually, even if the mesh within each region can be generated automatically, the analyst is required to input mesh density data for all the sides of each mappable region.

In 2020 every educational institution moved their didactics toward an online platform. Every course had to introduce and experiment with new forms of didactics that prevent in-person events, either in lectures or laboratory. Courses of design traditionally require a strict relation between student-instructor and student-student. The need to operate by moving the contact to an online connection creates, at the beginning of the period, a lot of distrust among teachers of such courses. The "Machine Drawing" course is one of these. Briefly recalling how the courses have been revised, with the employment of a communication platform like Teams®, the answers, given by students, are collected and the differences along the time are highlighted. Three academic years have been considered:

In this work the mechanisms of how humour facilitates creative problem solving during the conceptual phase of product design will be investigated. From the educational point of view all the activities that tend to reduce fixation during conceptual design are welcome, because students without specific experiences in work group and in generating original ideas reproduce always what is already known. In order to study the impact of humorous visual stimuli on creativity an experiment was performed. A sample of students of a MSc class in Management Engineering was divided into two sets and engaged to generate ideas concerning benches and shoe racks by Brainwriting (635 method) in two different ways: without stimulus and with stimulus. Three experts evaluated the concepts proposed in the generation phase and the Torrance Test ...

They must share the responsibility for best solution identification to accordingly answer the customer needs and to authorize the production of products that can have success with a positive economic return. Higher education curricula should prepare such professionals, and this is the reason because courses of product design are proposed to such classes. Even the programmes of the corresponding courses are necessarily different the part related to concept generation is similar. The work aims is to identify analogies and differences between the classes of Mechanical Engineering and Management Engineering, both in the way of leading the generation of concepts and in how the concepts generated have eventually reached the goals of innovation.

In general, the design of an industrial product needs several competencies that work conjointly, in the respect of many constraints that urge from the firm' departments. Last but not least sustainability is gaining a relevant role, since the recent past, and absolutely not deferred for the destiny of humankind on earth in the future. Design Matrix is the first array that designers should compose in order to verify the feasibility of product architecture since it put in relation functional requirements and design parameters. Clearly, designers are really far from the embodiment of valid proposals, at this moment. It is necessary to map this information to other data structures that allow them to follow the evolving architectural work, in which physical components or effective parts perform the actions that satisfy functional requirements. Design Structure Matrix (DSM) is a promising data structure that shows the relationship among all subsystems that compose the developing product. This structure can be arranged also to collect all the environmental parameters or indicators in order to have a rough sustainability assessment since the early design phases. The paper will discuss such kind of relation and apply it to a case study in order to clarify it.

It reports on cutting-edge topics in product design and manufacturing, such as industrial methods for integrated product and process design; innovative design; and computer-aided design. Further topics covered include virtual simulation and reverse engineering; additive manufacturing; product manufacturing; engineering methods in medicine and education; representation techniques; and nautical, aeronautics and aerospace design and modeling. The book is divided into eight main sections, reflecting the focus and primary themes of the conference. The contributions presented here will not only provide researchers, engineers and experts in a range of industrial engineering subfields with extensive information to support their daily work; they are also intended to stimulate new research directions,...
