The Recovery of the Optimal Damping Constant by the MRF Damper

2009

In this paper was studied a method to analyze the recovering of optimal damping constant because of temperature increasing in a shock absorber. The increasing on temperature leads to decreasing that constant by mean dynamic viscosity such to modify the dynamic behavior of a 2DOF system built-up by sprung and unsprung mass. A MagnetoRheological damper was designed according with the desired optimal damping constant once fixed temperature design. It was seen that the increasing of temperature this constant is lost. As MagnetoRheological-Fluids allows us to increase the viscosity, we use a control signal by a state feedback of reduced order to create a such magnetic induction field to recover …

Beliefs about oral corrective feedback in an Argentinean EFL university classroom : their impact on a teacher’s classroom actions

2019

Beliefs about oral corrective feedback (OCF) are essential components in the EFL classroom, especially when learning the speaking skill since teachers have to strike a delicate balance between the provision of OCF without negatively affecting students’ emotions. During the last years, many scholars have devoted great attention to the influence of affective factors in the learning of foreign languages. Among these factors, beliefs held by teachers and students have proved to impact significantly on the processes of teaching and learning a foreign language. The aims of this paper are: to describe the beliefs held by an Argentinian EFL teacher about OCF and to describe how her beliefs might sh…

Digital control circuitry for the p53 dynamics in cancer cell and apoptosis

2010

Abstract Experimental work and theoretical models deduce a “digital” response of the p53 transcription factor when genomic integrity is damaged. The mutual influence of p53 and its antagonist, the Mdm2 oncogene, is closed in a feedback. This paper proposes an aerospace-based architecture for translating the p53/Mdm2/DNA damage network into a digital circuitry in which the optimal control theory is applied for obtaining the requested dynamic evolutions of some considered cell species for repairing a DNA damage. The purpose of this paper is to demonstrate the usefulness of such digital circuitry design to detect and predict the cell species dynamics for shedding light on their inner and mutua…

Feedback and Communication in Active Hydrogel Spheres with pH Fronts: Facile Approaches to Grow Soft Hydrogel Structures

2021

Abstract Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life‐like materials, we compartmentalized urea‐urease and more complex urea‐urease/ester‐esterase pH‐feedback reaction networks into hydrogel spheres and investigate how fuel‐driven pH fronts can be sent out from these spheres and regulated by internal reaction networks. Membrane characteristics are installed by covering urease spheres with responsive hydrogel shells. We then encapsulate the two networks (urea‐urease and ester‐esterase) separately into different hydrogel spheres to devise communication, pattern formation and attracti…

To feed back or to feed forward? : Students' experiences of and responses to feedback in a Finnish EFL classroom

2017

Good feedback is a powerful element in learning. Ultimately, however, the impact feedback has on learning depends on how the learner responds to that feedback. So far, foreign or second language studies on feedback have mainly concentrated on different methods of error correction, not on students’ responses to feedback in general. This study aims to find out what students thought of the feedback they had received in their EFL studies. Furthermore, the study seeks to discover students’ different responses to that feedback. The data was gathered using a web-based questionnaire filled out by 140 students. The students, aged 17–19, were all from a single Finnish upper secondary school. The data…

Beyond error correction in EFL writing in a Finnish upper secondary classroom : a practical approach

2023

In Finland, teachers have considerable autonomy over their assessment practices. Recent studies suggest that FL/L2 teachers, particularly at the upper secondary school, primarily focus on summative assessment rather than on formative assessment and feedback, which is in contrast with the latest Finnish National Core Curricula. Furthermore, while appreciating teacher feedback, learners do not perceive it as an integral part of assessment. In this paper, we propose formative classroom practices to support the learning process and go beyond error correction in FL/L2 writing. These practices are grounded on our earlier research, and they focus mainly on two themes: fostering learner choice in f…

Lukiolaisten vertaispalaute verkkoympäristössä

2015

This case study addresses high school students’ peer feedback in an online wiki-environment. In the study the students worked in three small groups and wrote short texts. Their assignment was taken from the literacy skills test of the Finnish Matriculation Examination, autumn 2010, and the source text in question was an excerpt from the novel Askeleen jäljessä (One Step Behind) by Henning Mankell. The groups gave each other feedback about their written texts, being instructed to focus on assignment, content, parse and language. My research questions were: What kind of feedback did the students give each other? How did they structure the feedback? I conducted a content analysis to analyse th…

Strategic responses of medium sized firms: The role of TMT’s perceptions and characteristics in decision making processes

2017

Many decisions made by the organization’s top management team (hereafter called indifferently TMT or top management team) have a high likelihood of failure (Nutt, 1999). This situation might be shocking but indeed, it is much more common than one might think (Bloom et al., 2012). In fact, we can easily realize this reality when reading the current business press where we will probably be confronted with several cases of failures that have been caused by any type of TMT decisions. Of course, we will also see cases of success, exemplifying managers and recipes of good practices (e.g., Eide et al., 2016; Schrage, 2013); but these will be minor. Thus, as Bloom et al. (2012) state, the group of …

Opetusviestintä heterogeenisen kolmannen luokan ryhmällä

2012

Tämän tutkimuksen tarkoituksena oli selvittää, miten opettaja antoiinstruktion ja palautteen verbaalista ja nonverbaalista viestintää käyttäen heterogeenisen kolmannen luokan liikuntatunneilla sekä miten hän opetusviestinnässään huomioi oppilaiden yksilöllisyyden ja ryhmässä ilmenevän häiriökäyttäytymisen. Lisäksi tutkimuksessa selvitettiin, miten opettajan käyttämä opetusviestintä näyttäytyi oppilaiden toiminnassa liikuntatunneilla. Tutkimus toteutettiin laadullisena tapaustutkimuksena naisopettajan opettamassa 28 oppilaan (17 tyttöä, 11 poikaa) kolmannen luokan liikuntaryhmässä. Oppilasryhmä oli liikunnallisesti, oppimisvalmiuksiltaan sekä sosiaalisilta taidoiltaan heterogeeninen. Aineist…
