DIMENSIONAL STABILITY OF REINFORCED MATRICES.
1983
Particulate fillers are often used to improve the dimensional stability of polymeric items obtained through processing techniques such as injection molding, deep drawing, hot stamping, etc. In these operations the material undergoes large multiaxial deformations which result in molecular orientation and remain as frozen-in stresses during cooling of the material. Once the formed objects are exposed to sufficiently high temperatures, various degrees of spring-back take place and subsequent changes in shape and dimension occur (1).
Movements by Drawing: Avant-Garde Set-Design and Sound Landscapes
2018
The article deals with the study of visual images produced by the movement through the drawing’s set-design realized between 1920 and 1930, moment of theatre revolution, which saw the cooperation of different sectors of art, including photography, painting, architecture, cinema, dance, sculpture, and music. The visual values that triggered the theorization of the artistic avant-garde and, subsequently, the production of the scenographic drawing, in form and space, constitute a corollary of dynamic systems, a metaphor of the deconstructed movement through the figuration of the idea and at the same time signification of the interpretative distortion. The aim is to deepen the issue of movement…
An integrated multiobjective design tool for process design
2006
An integrated multiobjective design tool has been developed for chemical process design. This tool combines the rigorous process calculations of the BALAS process simulator and the interactive multiobjective optimization method NIMBUS. With this design tool, the designer can consider several conflicting performance criteria simultaneously. The interactive nature of this tool allows the designer to learn about the behavior of the problem. To illustrate the possibilities of this design tool, two case studies are considered. One of them is related to paper making while the other one is related to power plants.
Kustības attēlojuma apguve vizuālajā mākslā 9. klasē
2020
Darba autore Madara Indriksone ir izstrādājusi diplomdarbu par tēmu “Kustības attēlojuma apguve vizuālajā mākslā 9. klasē”. Tās mērķis ir izpētīt kustību attēlojumu, ko atspoguļo zīmējumu virknē un to plaknē. Balstoties uz izpētītajām tēmām un vizuālās mākslas mācību priekšmetu 9. klasei, ir sastādīta uzdevumu kopa šajā priekšmetā. Uzdevumu kopas tika veiktas, pārbaudītas un realizētas prakses laikā, atspoguļotas diplomdarbā. Stundas tiek veidotas ar pakāpenisku pieeju, mērķi izveidot skolēniem kustīgās grāmatiņas (Flip book), kurās tiek atveidotas kustības futūrisma stilā. Atslēgas vārdi – futūrisms, kustība, kustīgās grāmatiņas, skice, zīmējumu virkne
Learner-generated drawings in physics education
2013
Different kinds of visual representations, such as graphs and drawings are important in education but especially in science education. Little attention is paid especially to drawings. Students are required to examine drawings and assimilate the information conveyed by them but not much attention is paid to the students’ own drawings. Arguments can be made for the importance of learner-generated drawings in science education. The subject of this thesis is the use of learner-generated drawings in physics education. A study was conducted to study the use of learner-generated drawings as a tool for meaning-making. The study involved 36 upper secondary school students who were given a drawing as…

Abstract The main conclusions from the Working Group 3 presentations and deliberations at NuFact’00 are summarized.
Search for excited leptons in Z0 decay
1990
Due to the severity of system-wide power outages, though their probability of occurrence is slight, regulatory authorities require that a system restoration plan be drawn up and kept up to date at all times. The power outage that affected northeastern North America in 2003 proved the need for such a requirement. The particular structure of Hydro-Quebec's power system requires the use of a highly specific system restoration procedure. The daily preparation of the system restoration plan is based on a strategy whose application requires that a restoration sequence be drawn up that uses available equipment, the electrical behavior of which has been validated using appropriate studies. Over the…
The elastic body model: a pedagogical approach integrating real time measurements and modelling activities
2007
In this paper, we describe a pedagogical approach to elastic body movement based on measurements of the contact times between a metallic rod and small bodies colliding with it and on modelling of the experimental results by using a microcomputer-based laboratory and simulation tools. The experiments and modelling activities have been built in the context of the laboratory of mechanical wave propagation of the two-year graduate teacher education programme of Palermo’s University. Some considerations about observed modifications in trainee teachers’ attitudes in utilizing experiments and modelling are discussed.
La chiesa di Nostra Signora di Lourdes a Zagabria di Jože Plečnik. Analisi grafica
2019
Jože Plečnik (Ljubljana, 23rd January 1872 - Ljubljana, 7th January 1957) was, without any doubt, Otto Wagner's most brilliant pupil. During his tireless activity as an architect, he manages to touch a variety of absolutely heterogeneous themes, masterfully reworking the consolidated syntax of traditional architecture. In this survey we consider a relevant – although little investigated – aspect of the architect's work, that is the one linked to the typological innovations brought about by his work. In the case under examination – the work never done by the church of Our Lady of Lourdes in Zagreb – this innovation consists of the unusual arrangement of the four rows of columns that separate…
FEM Simulation of Laminated Lightweight Materials Processed through Single Point Incremental Forming
2015
The aim of present paper is to realize the FEM simulation of laminated lightweight material processed through single point incremental forming. Thus a laminated material, aluminum - polypropylene - aluminum (Al-PP-Al), as sheet 1.2 mm thickness was used. For these material the hardening curve was determinate. These values were used to describe elastic-plastic behavior of the material during single point incremental forming process simulation. Single point incremental forming process simulation aimed to assess the distribution of values and maximum and minimum strains, the material thickness of the specimen and the technological force for the two strategies for obtaining the truncated cone s…
