Researches Regarding the Use of Elctrohydraulic Servosystems at Industrial Robots
2012
This paper presents some researches regarding the use of electro-hydraulic servo-systems in driving the industrial robots, taking into consideration the conditions in which the robots work. The researches conducted upon a particular system, reveal the optimum design elements for obtaining a good behaviour in use, subsequently a good stability in use.
Comparative Analysis of Four New Alternative Types of Roundabouts: “Turbo”, “Flower”, “Target” and “Four-Flyover” Roundabou
2016
Analysis of literature shows that “modern roundabouts” nowadays exist in all European countries, as well as in more than 60 countries elsewhere in the world. Nowadays, a growing number of studies, presented in scientific and professional literature, point out a poor traffic safety characteristics of “standard” two-lane roundabouts and lower capacity then was expected. These problems are resolved in more ways in different countries; however the solution, whereby the number of conflict spots is diminished has proven to be the most successful. Lower number of conflict spots is one of characteristics of the alternative types of roundabouts. The alternative types of roundabouts are usually more …
Developing a Pedagogical Framework and Design Principles for STEM Learning Environment Design
2020
The need for effective and attractive learning environments (LEs) for science, technology, engineering, and mathematics (STEM) has been internationally recognized. Additionally, the connection between STEM learning and cross-curricular skills such as creativity, innovation, and entrepreneurship has garnered attention. A deep theoretical and empirical understanding is required when designing STEM LEs. In this study, a pedagogical framework for STEM LEs has been developed based on feedback from students, aged 10–18 years old, teachers, school directors, parents, and STEM professionals, and supported by the literature. First, representatives of key stakeholder groups in Belarus, Finland, Germa…
El management de las conductas socioemocionales. Una aproximación teórica y empírica desde el caso de los agentes de "contact centers"
2020
How is a specific type of emotion-related work conducts formed today? What principles guide these conducts and what effects do they have on those who work? The study of Contact Center agents allows us to understand how a set of personal qualities such as patience and good treatment of others, certain desires and personal impulses or even intimate sensations such as anguish or individual expectations have become managerialized emotions that end up modifying the inner attitudes of these agents. Within this framework, we propose a theoretical approach that integrates the work of Weber, Foucault and Elias, which invites us to reflect on a socio-emotional manner of leading one?s life (Lebensfu?h…
Generation of Design Principles as Knowledge Conversion - Elucidating Dynamics
2021
In this paper we apply the perspective of knowledge conversion with recent identified core elements for developing design principles to elucidate the dynamics of design principles. In the paper, the elements of influence, actors, and formulation are integrated in a knowledge conversion process of socialization, externalization, combination, and internalization – through which tacit knowledge is made explicit, shared, and turned into action. We exemplify this process with three empirical cases using action design research (ADR) to develop IT artifacts and generate design principles. Our paper shows the dynamics across a process of generating design principles. Viewing the generation of desig…
Implementing AI Ethics: Making Sense of the Ethical Requirements
2023
Society’s increasing dependence on Artificial Intelligence (AI) and AI-enabled systems require a more practical approach from software engineering (SE) executives in middle and higher-level management to improve their involvement in implementing AI ethics by making ethical requirements part of their management practices. However, research indicates that most work on implementing ethical requirements in SE management primarily focuses on technical development, with scarce findings for middle and higher-level management. We investigate this by interviewing ten Finnish SE executives in middle and higher-level management to examine how they consider and implement ethical requirements. We use et…
Forecasting : theory and practice
2022
Forecasting has always been at the forefront of decision making and planning. The uncertainty that surrounds the future is both exciting and challenging, with individuals and organisations seeking to minimise risks and maximise utilities. The large number of forecasting applications calls for a diverse set of forecasting methods to tackle real-life challenges. This article provides a non-systematic review of the theory and the practice of forecasting. We provide an overview of a wide range of theoretical, state-of-the-art models, methods, principles, and approaches to prepare, produce, organise, and evaluate forecasts. We then demonstrate how such theoretical concepts are applied in a varie…
On the Review of structure and effectiveness of the IFRS Foundation : the EAAs Financial Reporting Standards Committees view
2016
AbstractIn July 2015 the International Financial Reporting Standards (IFRS) Foundation launched its third five year review of its structure and effectiveness of the organisation. In a public call, the Trustees solicited stakeholders’ input on the relevance of IFRS Standards with respect to broadening the IFRS scope and to the impact of new technology, on the consistent application of IFRS and on the governance and funding of the International Accounting Standards Board and the IFRS Foundation. The European Accounting Association (EAA)’s Financial Reporting Standards Committee responded to this request for views by submitting a comment letter based on research-informed opinions. This article…

Phonon Driven Floquet Matter.
2018
The effect of electron–phonon coupling in materials can be interpreted as a dressing of the electronic structure by the lattice vibration, leading to vibrational replicas and hybridization of electronic states. In solids, a resonantly excited coherent phonon leads to a periodic oscillation of the atomic lattice in a crystal structure bringing the material into a nonequilibrium electronic configuration. Periodically oscillating quantum systems can be understood in terms of Floquet theory, which has a long tradition in the study of semiclassical light-matter interaction. Here, we show that the concepts of Floquet analysis can be applied to coherent lattice vibrations. This coupling leads to p…
