In the present paper we consider the problem of attitude synchronization for a system of rigid body agents. We provide distributed kinematic control laws for two different synchronization problems. In the two problems the objective is the same, i.e., to synchronize the orientations of the agents, but what is assumed to be measurable by the agents differs. In problem 1 the agents measure their own

A group of pre-service teachers were studied from two social practices, as teachers and as students. Their perceptions of mathematics concepts and beliefs about the mathematics teacher role were studied through questionnaires, interviews and classroom observations. Three students were selected as cases in this paper where their links between the concepts limits, derivatives, integrals and continui

This study is a follow-up investigation of the influence of the alloying elements Nd and La on the corrosionCorrosionby immersionImmersion of an extruded and heat-treated Mg10Gd. The previous study made clear that the age-hardened condition has the lowest corrosion rateCorrosion Rate but high pitting corrosionPitting corrosion susceptibility. The extruded Mg10Gd(1Nd)1La shows the lowest pitting fa

Quality of supply regulations are today in use in a large number of countries. While these regu-lations are likely to decrease the direct economical consequences from power outages it is less clear to what extent they take into account the societal criticality of consumers. In order to advance knowledge in this area, two different ways of estimating consequences of power outages are here contraste

This paper deals with a novel constitutive framework suitable for non-coherent interfaces, such as cracks, undergoing large deformations in a geometrically exact setting. For this type of interface, the displacement field shows a jump across the interface. Within the engineering community, so-called cohesive zone models are frequently applied in order to describe non-coherent interfaces. However,

We consider the problem of sharing sensitive files across users while relying on a common, untrusted third-party, e.g., a Cloud Storage Provider (CSP). Although users can rely on a secure peer-to-peer (P2P) channel for file sharing, this introduces potential delay on the data transfer and requires the sender to remain connected while the transfer process occurs. Instead, users can upload informati

This paper analyzes the problem and requirements of securely distributing software updates over the Internet,to devices in an Industrial Control System (ICS) and more generally in Internet of Things (IoT) infrastructurescontrolling a physical system, such as power grids and water supply systems. We present a novel approachthat allows to securely distribute software updates of different types, e.g.

Knowledge of infective endocarditis (IE) caused by Streptococcus dysgalactiae (SD) is limited. This study aimed to identify the clinical and microbiological features of SD-caused IE and to investigate any possible synergy between penicillin and gentamicin on SD isolates. Cases of IE 2008–2016 due to SD reported to the Swedish Registry of Infective Endocarditis (SRIE) were identified. Isolates were

The influence of boiling and storage on dietary fibre and digestible carbohydrates was investigated in eight different carrot cultivars. The content of total dietary fibre was in the range 252-291 g kg-1 DW and was generally at the higher end for the early cultivars and at the lower end for the late ones. During storage, there was a decrease in the soluble fibre content in all cultivars and genera

Current techniques to determine functional or effective connectivity from magnetoencephalography (MEG) and electroencephalography (EEG) signals typically involve two sequential steps: 1) estimation of the source current distribution from the sensor data, for example, by minimum-norm estimation or beamforming, and 2) fitting a multivariate autoregressive (MVAR) model to estimate the AR coefficients

In the eighteenth century, the portrait genre, previously restricted to royalty and nobility, became available to users from a broader social spectrum. All over Europe, physicians, scholars, writers, merchants, and proprietors had their portraits painted to mark their standing in society. However, not these grand paintings but their printed versions made the sitters known to the broader public. Bu

Occupational therapists support and enable people to partake in occupations or activities that are important to them; that they need/want/are expected to do. Occupational therapists are increasingly involved in services addressing the impact that social inequalities can have on peoples’ wellbeing. One way in which occupational therapy students in NUI Galway learn relevant skills is through service

The enactment of the revised Payment Services Directive (PSD2) by the European Union, has pushed banks to develop digital open banking platforms to enhance market competition and promote innovation in the banking industry. PSD2 mandates banks to offer APIs to provide access to banking data to external third-party providers (TPPs). This mandate might disrupt the role of banks since external complem

Rationale: Recent randomized controlled trials did not show cardiovascular benefits of continuous positive airway pressure (CPAP) in adults with coronary artery disease (CAD) and obstructive sleep apnea (OSA) in intention-to-treat analyses. It has been argued that exclusion of patients with OSA with excessive daytime sleepiness (EDS), who may be most likely to benefit from CPAP treatment, may be a
