MRI E-Conference electronic conference on ‘Marine Research Infrastructures (MRI): The need for better Information and Co-ordination’ 26-30 april 2004, final report

The MRI E-conference was an initiative of VLIZ and AWI in collaboration with EurOcean, ESF/Marine Board and IOC/UNESCO. The objective of this forum was to discuss the needs and expectations of the Scientific Community towards a common European approach for optimizing the coordination of marine research infrastructure. All the points made by the contributors are summarised and bundled in this final report

Deformation of Silica Aerogel During Fluid Adsorption

Aerogels are very compliant materials - even small stresses can lead to large deformations. In this paper we present measurements of the linear deformation of high porosity aerogels during adsorption of low surface tension fluids, performed using a Linear Variable Differential Transformer (LVDT). We show that the degree of deformation of the aerogel during capillary condensation scales with the surface tension, and extract the bulk modulus of the gel from the data. Furthermore we suggest limits on safe temperatures for filling and emptying low density aerogels with helium.Comment: 8 pages, 5 figures, submitted to PR

Raising awareness of the accessibility challenges in mathematics MOOCs

MOOCs provide learning environments that make it easier for learners to study from anywhere, at their own pace and with open access to content. This has revolutionised the field of eLearning, but accessibility continues to be a problem, even more so if we include the complexity of the STEM disciplines which have their own specific characteristics. This work presents an analysis of the accessibility of several MOOC platforms which provide courses in mathematics. We attempt to visualise the main web accessibility problems and challenges that disabled learners could face in taking these types of courses, both in general and specifically in the context of the subject of mathematics

Sparse Randomized Kaczmarz for Support Recovery of Jointly Sparse Corrupted Multiple Measurement Vectors

While single measurement vector (SMV) models have been widely studied in signal processing, there is a surging interest in addressing the multiple measurement vectors (MMV) problem. In the MMV setting, more than one measurement vector is available and the multiple signals to be recovered share some commonalities such as a common support. Applications in which MMV is a naturally occurring phenomenon include online streaming, medical imaging, and video recovery. This work presents a stochastic iterative algorithm for the support recovery of jointly sparse corrupted MMV. We present a variant of the Sparse Randomized Kaczmarz algorithm for corrupted MMV and compare our proposed method with an existing Kaczmarz type algorithm for MMV problems. We also showcase the usefulness of our approach in the online (streaming) setting and provide empirical evidence that suggests the robustness of the proposed method to the distribution of the corruption and the number of corruptions occurring.Comment: 13 pages, 6 figure

An empirical test for cellular automaton models of traffic flow

Based on a detailed microscopic test scenario motivated by recent empirical studies of single-vehicle data, several cellular automaton models for traffic flow are compared. We find three levels of agreement with the empirical data: 1) models that do not reproduce even qualitatively the most important empirical observations, 2) models that are on a macroscopic level in reasonable agreement with the empirics, and 3) models that reproduce the empirical data on a microscopic level as well. Our results are not only relevant for applications, but also shed new light on the relevant interactions in traffic flow.Comment: 28 pages, 36 figures, accepted for publication in PR

Gambaran Pengetahuan Pasien Tentang Pemasangan Gelang Identifikasi Pasien Di Instalasi Rawat Inap a Blu. Rsup. Prof. Dr. R. D. Kandou Manado

: Patient Safety Goals is a requirement to be implemented in all hospitals accredited by the Commission on Accreditation of Hospitals. The use of patient's identification bracelet is the first implementation of the six targets Patient Safety Goals, that is the accuracy of the identification of patients that aims to be able to identify patients who were admitted to the hospital, appropriately, at the time of service or treatment. Purpose: to know the description of the patient knowledge about the installation of the patient identification bracelet in inpatient A BLU RSUP Prof. Dr. R. D. Kandou Manado. Methods: this study used a descriptive survey. The sampling technique used is total sampling of respondent with 90 patients. Results: the study showed that knowledge most of the patients shave lack knowledge about the definition (68.9%), lack about purpose (67.8%), good about the use (53.3%), and good about characteristics (61.1%). Conclusion: description of the patient knowledge about the installation of the patient identification bracelet includes definition, purpose, the use and charateristics in inpatient A BLU RSUP Prof. Dr. R. D. Kandou Manado is in either category. Suggestions: patient's knowledge needs to be maintained so that properly maintained patient safety with the setting up of leaflets about identification bracelet will optimize patient safety policies that have been implemented in hospitals
