A new approach of the teaching of the subject Graphical engineering is developed at the Engineering School of the University of Salamanca, focusing the contents on the use of the CAD/CAM/CAE systems as useful tools for applying engineering problems related with the mechanical engineering instead of describing diverse software options. Thus, the contents of the subject are divided into two blocks, one devoted to the analysis of the results of simulation of movement of diverse mechanisms and the second devoted to the analysis of diverse cases of loading structural components by means of FEA module, both available in the Autodesk Inventor Pro suite which can be downloaded free by the students. This way, students can visualize and realize of the complexity of a design process in engineering.

Investigations of the dynamic behavior of structures have become increasingly important in the design process of mechanical systems. To have a better understanding of the dynamic behavior of a structure, the knowledge of the modal parameters is very important. The powerful method of experimental modal analysis has been used to measure modal parameters in many mechanical engineering problems. But the method was mainly applied to nonrotating structures. This presentation shows improvements of the classical modal analysis for a successful application in rotating machinery with nonconservative effects. An example is given, investigating the modal parameters of an elastic rotor with oil film bearings.

The paper outlines some of the engineering problems which arise in connexion with naval mining, and describes some of the weapons and devices used by Britain and Germany in the war of 1939–45. Although naval mining has a long history, its development is necessarily conducted under conditions of secrecy, and publication of information concerning it is possible only after a major war in which there has been a general disclosure of methods and materials employed by both sides. The popular conception of a mine is a spherical buoyant object which will explode if hit by a ship. The buoyant contact type is, however, only one of many forms now available. A number of these are illustrated here, and the variety may surprise those not familiar with the subject. Methods of laying, general principles of operation, and safety requirements are described, and the mechanical details of design of mineshells, fittings, components for control and firing circuits, and other features are mentioned. Naval mines have reached a state of considerable complexity and many fields of scientific knowledge are now called upon in making them effective weapons.

Abstract This paper describes a new module in embodiment design that updates the teaching of engineering design at Level 2 in the School of Mechanical Engineering at the University of Leeds. The new module is team-based, uses a 3D solid modeling system and emphasizes the process over the product of the design process. The module replaces one in which students worked alone to produce a detailed drawing of a sub-assembly at a drafting board. The development and content of the module, and the congruency of the learning outcomes with the level objectives, are described. Problems associated with the reliability and validity of assessing process-oriented team-based projects are considered.

This article examines the problems faced by the educators in the conditions of transformation of modern educational environments, which are associated with the need for identification of factors that contribute or impede professional self-realization. The transformation of educational environment of a university mainstreams the processes of goal-setting and possibility of personal becoming of an educator. The object of this research is the process of professional self-development of the educator in pedagogical university in the context of transformation of educational environment. The subject of this research is the key characteristics of goal-setting within the structure of planning professional future of the educator in the conditions of transformation of educational environment. The author defines the valuation levels (low, middle, high) of goal-setting for the professional pedagogical self-development of the educator in pedagogical university with consideration of its structural components, i.e. indicators (realization of the need for professional pedagogical self-improvement, strategic planning, precision of goal-setting, etc.). Assessment of the levels was conducted taking into account the indicators within its structure (dyads), which are logically interrelated and reflect the professional pedagogical self-development of the university educator. The overall potential of self-development of the educators in pedagogical university is enhanced by such semantic modalities as flexibility in achieving the set goals and creativity of planning professional future. The scientific novelty consists in the need for determination of fundamental characteristics of goal-setting within the structure of planning of professional future of the educator considering the requirement for their professional pedagogical self-improvement and transformation of modern educational environment. It was established that among the educators in pedagogical universities with regards to activation of development of potential of the pedagogue 65% of respondents noted that the professional pedagogical self-improvement is attended only if required by the university administration; 35% of respondents stated their willingness for self-improvement in the sphere of pedagogical professional, as well as outside it.

Two-stage exams consist of a traditionalpencil-and-paper examination written in class byindividual students, followed immediately by a secondsitting in which the students retake the same exam inteams (i.e. a collaborative test). The team test providesan immediate opportunity for students to discuss, debate,teach, and receive feedback on the subject matter. Itdraws on principles of goal-directed practice, timelytargeted feedback, and collaborative learning.The practice of two-stage testing is a defining featureof the Team-Based Learning approach, and is used forintroductory reading quizzes that begin each coursemodule. These have been part of the instructionalapproach in Mechanical Engineering at the University ofBritish Columbia for over a decade. In 2014, we haveextended two-stage testing to include midterm and finalexaminations. To accommodate the team portion, examswere shortened by approximately one third and questionswere reformatted to be easier to complete in teams.Students report a strong preference this approach(72% in favour) and report a resulting improvement intheir understanding of the course material (75%). Examperformance gains have also been observed. In almost allcases, teams outperform their strongest member, and it isnot uncommon that the weakest team outperforms thestrongest individual in the class. As an added benefit, therevised question structure that makes it easier for studentsto collaborate on exam writing has also simplified andexpedited the marking process.

The Impact

Course design in engineering should be able to address the core competencies that are required by the engineering profession. To implement this concept many courses are structured to include real-situation projects. From the view point of mechatronic engineering education, it is clear that a robotic project will be suitable to integrate the course contents. However, to provide necessary theoretical skills for students to solve real engineering problems, project only is not sufficient in the subject. In this paper the design and delivery of a subject in robotics at the University of Western Sydney (UWS) is presented and discussed. In particular, this paper reviews the concept behind the course contents, assessments and delivery design. The paper has also demonstrated the impact of such course design in student performance and perception using student survey results and final grades in classes.

Iceland Spar

In a former Graduates' Lecture delivered in 1913* the Lecturer described the general principles of Photo-Elasticity, and some applications to Engineering. The present Lecture was therefore devoted to a consideration of some developments of the subject which have taken place since, and attention was mainly directed to improvements in apparatus for photo-elastic investigation and to the results obtained by this method of research when applied to elucidate the action of cutting tools. A prime necessity in all such work is a beam of polarized light of large cross-section and considerable purity, and the scarcity of Iceland spar for Nicol's prisms of sufficiently large size has led to the use of other forms of polarizers, of which a very convenient one was described, consisting of a thin slice of Iceland spar suitably mounted between glass wedges, and provided with converging and diverging lens systems, whereby a beam of large cross-section and of great purity is obtained.

Intracellular Motility

Microtubules are involved in a number of forms of intracellular motility, including mitosis and bidirectional organelle transport. Purified microtubules from brain and other sources contain tubulin and a diversity of microtubule associated proteins (MAPs). Some of the high molecular weight MAPs - MAP 1A, 1B, 2A, and 2B - are long, fibrous molecules that serve as structural components of the cytamatrix. Three MAPs have recently been identified that show microtubule activated ATPase activity and produce force in association with microtubules. These proteins - kinesin, cytoplasmic dynein, and dynamin - are referred to as cytoplasmic motors. The latter two will be the subject of this talk.Cytoplasmic dynein was first identified as one of the high molecular weight brain MAPs, MAP 1C. It was determined to be structurally equivalent to ciliary and flagellar dynein, and to produce force toward the minus ends of microtubules, opposite to kinesin.
