Teaching Motion Control in Mechatronics Education Using an Open Framework Based on the Elevator Model
2022
Universities and other educational institutions may find it difficult to afford the cost of obtaining cutting-edge teaching resources. This study introduces the adoption of a novel open prototyping framework in the context of mechatronics education, employing low-cost commercial off-the-shelf (COTS) components and tools for the motion control module. The goal of this study is to propose a novel structure for the motion control module in the engineering mechatronics curriculum. The objective is to foster a new teaching method. From a methodology perspective, students are involved in a series of well-organised theoretical lectures as well as practical, very engaging group projects in the lab.…
International Vocational Education and Training Research: An Introduction to the Special Issue
2021
The seven articles in this special issue represent a wide range of international comparative and review studies by international research teams from China, Germany, India, Russia, Switzerland and Mexico. The presented projects are part of the national program "Research on the Internationalisation of Vocational Education and Training", funded by the German Federal Ministry of Education and Research (BMBF). An adapted version of Urie Bronfenbrenner���s ecological systems theory forms the conceptual framework of the special issue. The four system levels (micro, meso, exo and macro) are addressed by one article each. The article on the microsystem level focuses on the intended and implemented c…
Risku vadība Zviedrijas bankās
2021
Paaugstināta tirgus nepastāvība, finanšu krīzes un ekonomikas lejupslīde radīja risku pārvaldības ideju kā vienu no visvairāk pieaugošajām bažām banku nozarē. Pēdējās desmitgadēs, īpaši pēc 2008. Gada finanšu krīzes, riska pārvaldības jēdziens ir piedzīvojis transformācijas pārmaiņas. Šīs tēzes mērķis ir uztvert pašreizējo riska pārvaldības scenāriju bankās, kas darbojas Zviedrijas tirgū. Darbs sākas ar vēsturiskā un mūsdienu riska jēdziena analīzi, kam seko riska pārvaldības jēdziena novērtējums un tā piemērošana banku un finanšu iestādēs. Lai koncepcija būtu precīza un saprotama, ir apspriesta arī dažāda riska pārvaldības prakse un ietvars. Pētījums tika veikts, lai apgaismotu dažādus pri…
SOCIAL INFORMATION USE IS A PROCESS ACROSS TIME, SPACE, AND ECOLOGY, REACHING HETEROSPECIFICS
2007
Decision making can be facilitated by observing other individuals faced with the same or similar problem, and recent research suggests that this social information use is a widespread phenomenon. Implications of this are diverse and profound: for example, social information use may trigger cultural evolution, affect distribution and dispersal of populations, and involve intriguing cognitive traits. We emphasize here that social information use is a process consisting of the scenes of (1) event, (2) observation, (3) decision, and (4) consequence, where the initial event is a scene in such a process of another individual. This helps to construct a sound conceptual framework for measuring and …
The Affordances of Reading/Writing on Paper and Digitally in Finland
2014
The aim of this study is to investigate the impact of digital technologies on reading and writing in Finland. The perceived affordances of reading and writing on paper and digitally are compared by analysing written essays collected from 25 communication students in 2013. Research design is replicated from a study of Fortunati and Vincent that concerns Italian students. Results show that Finnish students perceive more positive than negative affordances regarding reading on paper, while reading on screen attracts fewer virtues. In this respect, results are in line with the Italian study. Unlike in Italy, students in Finland value writing on a keyboard especially because it enables editing th…
From corona virus to corona crisis : the value of an analytical and geographical understanding of crisis
2020
Abstract The term ‘crisis’ is omnipresent. The current corona virus pandemic is perceived as the most recent example. However, the notion of crisis is increasingly deployed as a signifier of relevance, rather than as an analytical concept. Moreover, human geography has so far little contributed to the interdisciplinary crisis research field which is fixated on the temporal aspects of crisis but neglects its spatiality. Against this background, the first aim of the paper is to demonstrate the value of thinking about crisis analytically. Therefore, we introduce theoretical knowledge developed within a recently emerging literature on crisis management. Second, we demonstrate the relevance of i…
Fads and Facts of E-Government: A Review of Impacts of E-government (2003–2009)
2010
This paper analyzes the impacts of e-government as reported in 55 first-hand empirical peer-reviewed journal publications during the period 2003–2009, using a conceptual framework to identify ICT (information and communication technology) impacts on four domains within the public sector: capabilities, interactions, orientations and value distribution. The analysis shows that research findings mostly report positive impacts in all four dimensions. In the empirical research, the majority of impacts from ICT are reported within the domain of capabilities, which is also the domain that features the most balanced mix of positive and negative findings. Findings show that although e-government has…
Water Adsorption in Flexible Gallium-Based MIL-53 Metal–Organic Framework
2014
Understanding the adsorption of water in metal–organic frameworks (MOF), and particularly in soft porous crystals, is a crucial prerequisite before considering MOFs for industrial applications. We report here a joint experimental and theoretical study on the behavior of a gallium-based breathing MOF, Ga-MIL-53, upon water adsorption. By looking at the energetics and thermodynamics of Ga-MIL-53, we demonstrate why it behaves differently from its sibling Al-MIL-53, showing a different phase at room temperature (a nonporous phase) and the presence of a hydrated narrow-pore structure at gas saturation pressure. Moreover, we present a complete water vapor pressure vs temperature phase diagram of…
A MODEL FOR VESTIBULAR FUNCTION IN ALTERED GRAVITATIONAL STATES
1979
ABSTRACT During evolution, the vestibular organ was made to serve mainly two purposes: 1) to guide eye movements during sharp turns, so that the point of fixation in the visual field can be kept steady, a function accomplished by the semicircular canal system and 2) to indicate the terrestrial vertical, so that upright posture and gait can be maintained even in the dark. The otolith system serves the latter purpose. Since the function of the semicircular canal system does not depend on gravity, it is not grossly disturbed by gravitational levels different from 1 g . The proper function of the otolith system depends entirely on the presence of a gravitational force vector of 9.8/m/sec2 direc…
Augmented Reality of the Middle Ear Combining Otoendoscopy and Temporal Bone Computed Tomography
2018
International audience; HYPOTHESIS:Augmented reality (AR) may enhance otologic procedures by providing sub-millimetric accuracy and allowing the unification of information in a single screen.BACKGROUND:Several issues related to otologic procedures can be addressed through an AR system by providing sub-millimetric precision, supplying a global view of the middle ear cleft, and advantageously unifying the information in a single screen. The AR system is obtained by combining otoendoscopy with temporal bone computer tomography (CT).METHODS:Four human temporal bone specimens were explored by high-resolution CT-scan and dynamic otoendoscopy with video recordings. The initialization of the system…
