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

2001
Abstract The main conclusions from the Working Group 3 presentations and deliberations at NuFact’00 are summarized.
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…
The role of representation and technology in product configuration.
2017
The relationship between design and visualization requires considerations about methods and techniques of representation. This is especially important today, even for industrial products as information technology is affecting their visualization and product configurator are changing the relationship among the actors involved in their production.
Researches Regarding Optimising the Contouring Precision of CNC Laser Cutting Machines
2014
This paper presents some experimental researches regarding the manufacturing accuracy of a profiling machine together with an approach to eliminate the positioning and contouring errors. A mathematical model based on transfer functions is used as starting approach in order to tune the feed drives of the machine. The accuracy of the profiling machine is tested before and after the tuning process, in order to validate the proposed approach. There are unfolded both positioning tests along one axis and contouring tests on two axes.
An approach to evaluation of sheet bending force under successive multiaxial stress condition
2009
A new bending under tension test is presented in this paper. This method tries to evaluate bending forces in sheet under successive multiaxial stress condition. This test is carried out in only one step with a pinned cylinder over a material that has been previously deformed to pure shear condition. Due to that, the bending process is made under higher back tension forces than the ones involved in the common methods previously studied in the literature. This entails high pressure values in the sheet-bending tool contact that affects the corresponding friction process. Material is strongly strengthened as a consequence of the deformation practiced in it, and as a result of that, bending forc…
Design, build-up and optimization of a fast quenching device for polymeric thin film
2014
In this work an innovative apparatus for the characterization of polymer solidification under very high cooling rates (up to thousand of K/s) is described, according to the continuous cooling transformation approach adopted in metallurgy for studying structure development in metals. The proposed model experiment is addressed to design a method for the characterization of non-isothermal solidification behaviour, encompassing typical cooling conditions of polymer processing. Only temperature history determines the structure formed, as melt solidification takes place in quiescent conditions. With respect to the device previously developed by the authors [1, 3] the present equipment presents th…
Asymmetric Single Point Incremental Forming of Sheet Metal
2005
The use of computers in manufacturing has enabled the development of several new sheet metal forming processes, which are based upon older technologies. This paper describes modifications that have been made to traditional forming methods such as conventional spinning and shear forming, forming processes in which deformation is localized. Recent advances have enabled this localized deformation to be accurately controlled and studied. Current developments have been focused on forming asymmetric parts using CNC technology, without the need for costly dies. Asymmetric Incremental Sheet Forming has the potential to revolutionize sheet metal forming, making it accessible to all levels of manufac…
