Tail Removal Block Validation: Implementation and Analysis

2018

In this paper a solution for the removal of long tail blocktimes in a proof-of-work blockchain is proposed, implemented and analysed. Results from the mainnet of the Bismuth blockchain demonstrate that the variances in the key variables, difficulty level and blocktime, were approximately halved after the tail removal code was enabled. Low variances in difficulty and blocktimes are desirable for timely execution of transactions in the network as well as reduction of unwanted oscillations in the feedback control problem.

Using assessment for learning mathematics with mobile tablet based solutions

2014

Published version of an article in the journal: International Journal of Emerging Technologies in Learning (iJET). Also available from the publisher: http://dx.doi.org/10.3991/ijet.v9i2.3219 This article discusses assessment for learning in mathematics subjects. Teachers of large classes face the challenge of regularly assessing students’ ongoing mathematical learning achievements. Taking the complexity of assessment and feedback for learning as a background, we have developed a new approach to the assessment for learning mathematics at university level. We devised mobile tablet technology supported assessment processes, and we carried out user studies in both Rwanda and Norway. Results of …

A Nonlinear Control of Synchronous Reluctance Motors (SynRM) Based on Feedback Linearization Considering the Self and Cross-Saturation Effects

2019

This paper proposes a nonlinear controller based on feedback linearization for Synchronous Reluctance Motors (SynRM) drives that takes into consideration the self and cross-saturation effects. Such control technique permits the dynamics of both the speed and flux loops to be maintained constant independently from the load and the saturation of the iron core. The proposed technique has been tested experimentally on a suitably developed test set-up.

Facilitadores y flujos de aprendizaje como agentes dinamizadores en la gestión del capital intelectual y la performance corporativa

2012

El propósito fundamental de esta investigación es explorar hasta qué punto los componentes del capital intelectual establecen relaciones con los facilitadores para la creación de conocimiento, también con los flujos de aprendizaje feedback y feedforward, y cómo pueden estos, a su vez, influir en la performance de la organización. Para la consecución de este objetivo hemos estructurado este trabajo en tres grandes bloques. El primero de ellos incluye los fundamentos teóricos y ofrece una revisión de la investigación previa y de los conceptos relevantes de este trabajo. Está estructurado en tres capítulos: en el primero se realiza una aproximación del capital intelectual en el marco de la Teo…

Pathways Through Peer Assessment: Implementing Peer Assessment in a Lower Secondary Physics Classroom

2020

AbstractPeer assessment has been shown to advance learning, for example, by improving one’s work, but the variance of learning benefits within or between studies has not been explained. The purpose of this case study was to examine what kinds of pathways students have through peer assessment and to study which factors affect them when peer assessment is implemented in the early stage of physics studies in the context of conducting and reporting inquiry. Data sources used include field notes, audio recordings of lessons, student lab reports, written peer feedback, and student interviews. We examined peer assessment from the perspective of individual students and found 3 profiles of peer asse…

Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample

2015

The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant …

Musical Feedback: a new strategy in gait training for Parkinson’s Disease Patients

2016

Rhythmic auditory stimulation (RAS) for gait training in Parkinson’s disease has been applied successfully over the last three decades. The purpose of this study is to investigate the effectiveness of an extended concept of RAS, which is not limited to musical stimulation, but also includes musical feedback. In our study the comparison between RAS, musical feedback (MF), and no musical stimulation (NM) is conducted on a sample of 20 idiopathic Parkinsonian patients in a randomized cross-over design. Each patient has the task to walk for six minutes for each condition, focusing on stride length. The patient is instructed to make long steps and is connected with a software that is able to rec…

Pupil dilation under constant illumination is a physiological marker where modulation is related to several cognitive functions involved in daily decision making. There is evidence for a role of pupil dilation change during decision-making tasks associated with uncertainty, reward-prediction errors and surprise. However, while some work suggests that pupil dilation is mainly modulated by reward predictions, others point out that this marker is related to uncertainty signaling and surprise. Supporting the latter hypothesis, the neural substrate of this marker is related to noradrenaline (NA) activity which has been also related to uncertainty signaling. In this work we aimed to test whether …

Muntlig och skriftlig feedback på gymnasienivå : en fallstudie

2016

Opettajan antamalla palautteella on keskeinen rooli opetuksessa, sillä sen avulla oppilas saa tietää, miten hän etenee omassa oppimisprosessissansa. Lisäksi palautteella on vaikutus oppilaan motivaatioon ja itsetuntoon. Tämän tutkimuksen tavoitteena oli selvittää, miten lukiolaiset haluavat saada suullista ja kirjallista palautetta ruotsin ja englannin opetuksessa. Tarkastelin myös, miten opettajat antavat palautetta oppilaillensa ja onko kielten välissä havaittavissa mitään eroja. Tutkimusaineistoni muodostui 45 lukiolaisesta ja kahdesta opettajasta. Observoin kolme tuntia ruotsin opetusta ja kolme tuntia englannin opetusta, minkä jälkeen sekä lukiolaiset että opettajat vastasivat kyselyyn…
