Workshops of innovation in chemical engineering to train communication skills in science and technology
2019
Abstract This paper shows the application of an innovate pedagogical approach based on the project-based learning technique, focused on the training of communication skills in the framework of a workshop of innovation in chemical engineering. Written, graphical verbal, and non-verbal communication were tackled. For that purpose, a project of technological innovation was developed by the students in teams within the specific area of chemical engineering. A professional-like environment was simulated by a final workshop where the students defenced and supported their project by using oral presentation and production of a poster and a video. Several surveys were performed before and after the …
A DC behavioral electrical model for quasi-linear spin-valve devices including thermal effects for circuit simulation
2011
An advanced model for quasi-linear spin-valve (SV) structures is presented for circuit simulation purposes. The model takes into account electrical and thermal effects in a coupled way in order to allow a coherent representation of the sensor physics for design purposes of electronics applications based on these sensor devices. The model was implemented in Verilog-A and used in a commercial circuit simulator. For testing the model, different SV structures have been specifically fabricated and measured. The characterization included DC measurements as well as steady-state and transient thermal analysis. From the experimental data, the parameters of the model have been extracted. The model re…
Image og the Teacher in Schools Websites – Representative of the School
2015
Article consists of three parts - theoretical, empirical research and recommendations for improvement the school website photo galleries. Publication analyses ideas (Weber&Mitchell, Ķestere, Kaļķe, Fischer&Kiefer, Veide) that reveal importance of the teacher's image in the representation of the school, significance of the picture and selfpromotion in the school context. The empirical study consider teacher’s image in 17 Latvian school website photo galleries and surveys 102 primary school student’s parents to find out their views on the school website photo galleries impact on the selection of the school for their children. Analysis of the theoretical literature and interpre…
Combination of modal responses consistent with seismic input representation
2004
The well-known modal superposition method for the evaluation of seismic response by the complete quadratic modal combination rule (CQC) is revisited. The most widely used version of the CQC rule utilizes correlation coefficients derived for white-noise excitation and neglects the influence of peak factor variation on the response. Here a simplified procedure for evaluation of correlation coefficients and peak factors consistent with the power spectral density of seismic excitation is proposed. The procedure is based on an approximate analytic expression for direct evaluation of the power spectral density of the excitation consistent with any prefixed response spectrum, and the evaluation of…
Optimization of the contact surface shape of a shrinkage fit
1998
Amongst many processes existing today for the assembly of two cylindrical parts, the shrinkage fit is commonly used. However, in the calculation methods, the contact surfaces are assumed to be perfect. Therefore, in order to apply these, the standards necessitate very small geometrical tolerances. The objective of the present paper is to show that it is possible to take into account form defects by closely conformed contact modelling and to have a good representation of reality: form defects always exist to an increasing extent and are inherent in all kinds of manufacturing processes. Finally, it is shown that the presence of defects can be beneficial, allowing optimization from both a mech…
Unfolding Cyberspace: Cyberplaces of the Contrade and the Style of Representation in the Global Arena
2017
This chapter shows that, in the online representation of the contrade of Siena, the global level is not opposed to the local but is, instead, a particular way in which the local is represented. The method of placing their community on the global stage is that of an idealised inhabitation, one which also allows them to keep control over the formation of their collective identities. Furthermore, it shows that in the globalised world, the neighbourhoods of Siena encounter a global interest in their way of life which has made them alter their modes of self-representation . In order to position themselves in both local and global contexts, they have chosen to use the World Wide Web to present th…
Using human-values as a guide for understanding worthy design directions in augmented reality
2016
Augmented reality is a fast developing field, which will no doubt gain strong footing in the area of social media in the near future. Recently, Google Glass placed AR towards the top of the technological hype curve in regards to interaction possibilities, information overlay, information search and recording. Questions still remain however, regarding the added-value that AR offers to already existing interaction modes and technologies. In this study four concepts were designed and tested via video scenarios. The concepts related to three main product categories: educational tools; information presentation; and x-ray vision. The results positively reflected on the application of AR for educa…
A local linear black-box identification technique for power converters modeling
2009
In this paper, a black-box modeling technique for power electronic converters, also used in automotive environment is presented. The aim of this work is to provide a simple yet versatile and powerful tool to schematize complex electric devices in vehicular appliances, in order to fulfill the electromagnetic compatibility already during the project stage. By using input and output measured data, a composite local linear state space model is built up. Radial basis functions are used as weights for the local systems. The proposed approach is validated and applied in modeling a DC/DC converter for DC motors, a pulse width modulation inverter and a controlled rectifier.
Las fisuras de la nación : tensiones y lecturas político-religiosas sobre la conquista de América en el siglo XVIII
2020
La conquista de América generó una notable cantidad de discursos épicos, de carácter político y literario, que contribuyeron al reforzamiento de los tópicos imperiales, religiosos y patrióticos. Preocupada por la mala imagen del país en el extranjero, las élites políticas e intelectuales al servicio de Carlos III y Carlos IV promocionaron la defensa de los conquistadores, pese a la difusión de una corriente crítica con el heroísmo militar, tangible en la opinión pública europea. En el marco del reformismo borbónico, se reconstruyen los grupos e individuos que, desde lugares y posturas muy diferentes, posibilitaron el éxito de este discurso preponderante, que subrayaba la estrecha colaboraci…
Environmental activism as counter-hegemony? A comparative critical discourse analysis of self-representations of radical environmental organisations
2021
Działalność organizacji ekologicznych wiąże się z odrzucaniem zapewnień o wystarczających działaniach ochronnych i kwestionowaniem dominujących praktyk kulturowych. Jednak aby skutecznie mobilizować opinię publiczną, ruchy ekologiczne muszą prezentować się jako wiarygodne i akceptowalne, choć ich dążenia kwestionują wartości kultury hegemonicznej. Niniejsze studium to analiza porównawcza manifestów trzech radykalnych organizacji ekologicznych, Extinction Rebellion (UK) Deep Green Resistance (USA) i Pracowni na Rzecz Wszystkich Istot (Polska), pod kątem językowych, retorycznych i wizualnych strategii prezentacji wartości opozycyjnych do głównego nurtu kultury w kontekście kryzysu klimatyczne…
