Interprofessional collaboration during an emergency ward’s rounds
2015
Purpose – The purpose of this paper is to explore interprofessional collaboration during ward rounds on a Finnish emergency and infection ward from the viewpoint of three central professional groups: physicians, nurses and secretaries. Design/methodology/approach – The authors utilise an ethnographically informed approach, with observations and interviews as the data collection devices. The data comprise ten interviews with staff members and ten hours of observations. The data were analysed using qualitative thematic analysis. Findings – The ward rounds were found to be rather physician- and medicine-centred, and mostly not interprofessional. Nurses and secretaries in particular expressed …
MATLAB-based educational software for exploratory data analysis (EDA toolkit)
2009
This article presents an educational software developed in order to enable engineering students to gain insight into data sets via the exploratory data analysis (EDA). This software has been developed using the MATLAB GUIDE tool. This article shows the program suitability for learning EDA in different engineering courses related to data analysis such as data mining or data processing courses. © 2009 Wiley Periodicals, Inc.

Active learning in a real-world bioengineering problem: A pilot-study on ophthalmologic data processing
2019
Active learning is a format alternative to the conventional lecture/recitation/laboratory; research results have reported that it is suitable to encourage student inquiry and foster peer mentoring. Although the availability of computer-based learning materials in biomedical sciences is increasing, there are relatively few studies aimed to integrate traditional methods of teaching with inquiry-based approaches utilizing these Information and Communication Technologies (ICT) tools. This paper describes a pilot-study on a comprehensive active laboratory course about digital ophthalmologic signal classification, experienced by a group of undergraduates in Bio-Electronic Engineering. During the …
Electromagnetic and ultrasonic investigations on a Roman marble slab
2011
The archaeological museum of Rome asked our group about the physical consistency of a marble slab (second to third century AD) that recently fell during its travel as part of an exhibition. We decided to use different methodologies to investigate the slab: namely a pacometer (Protovale Elcometer) to individuate the internal coupling pins, and ground-penetrating radar (GPR) (2000 MHz) and ultrasonic (55 kHz) tomographic high-density surveys to investigate the internal extension of all the visible fractures and to search for the hidden ones. For the ultrasonic data, tests were carried out to optimize the inversion parameters, in particular the cell dimensions. Surely, the choice of cell size …
MDA: a MATLAB-based program for morphospace-disparity analysis
2003
A MATLAB® program that examines patterns of state-space occupation is described. Four subroutines are available with which to visualize morphospace patterns: (i) in terms of their features such as dispersion, aggregation and location, thereby allowing users to extract complementary quantitative information about how the state-space is structured, and (ii) in terms of changes in those patterns that can be compared with other biotic (e.g., extinction, origination rates) or abiotic (e.g., environmental proxy) information. The program incorporates many of the latest and most widely used statistical parameters for describing multivariate spaces. The parameters are estimated on the basis of boots…
Optical remote sensing and the retrieval of terrestrial vegetation bio-geophysical properties – A review
2015
Abstract: Forthcoming superspectral satellite missions dedicated to land monitoring, as well as planned imaging spectrometers, will unleash an unprecedented data stream. The processing requirements for such large data streams involve processing techniques enabling the spatio-temporally explicit quantification of vegetation properties. Typically retrieval must be accurate, robust and fast. Hence, there is a strict requirement to identify next-generation bio-geophysical variable retrieval algorithms which can be molded into an operational processing chain. This paper offers a review of state-of-the-art retrieval methods for quantitative terrestrial bio-geophysical variable extraction using op…
Effectively and efficiently supporting crowd-enabled databases via NoSQL paradigms
2013
In this paper we provide an overview of the Hints From the Crowd (HFC) project, whose main goal is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions (the reviews). The HFC prototype has been developed as a web application, independent of the particular application domain of the collected product reviews. Queries are performed by evaluating a text-based ranking metric for sets of re…
Scalable Monitoring System for Clouds
2013
Although cloud computing has become an important topic over the last couple of years, the development of cloud-specific monitoring systems has been neglected. This is surprising considering their importance for metering services and, thus, being able to charge customers. In this paper we introduce a monitoring architecture that was developed and is currently implemented in the EASI-CLOUDS project. The demands on cloud monitoring systems are manifold. Regular checks of the SLAs and the precise billing of the resource usage, for instance, require the collection and converting of infrastructure readings in short intervals. To ensure the scalability of the whole cloud, the monitoring system mus…
Openstack iesaistes mehānismu īstenošana
2022
Andris Lapiņš izstrādāja bakalaura darbu ,,Openstack iesaistes mehānismu īstenošana”. Bakalaura darba mērķis ir izpētīt, notestēt un censties implementēt darba vietas mākoņa sasaisti ar izvēlētās kopienas federatīvo mākoni, kā arī sasaisti ar darba vietā pieejamo datu glabāšanas sistēmu. Bakalaura darba uzdevumi ir izvēlēties vislabākās tehnoloģijas virtuālās infrastruktūras izveidei atbilstoši darba vietas prasībām un turpināt darbu pie jaunās mākoņa iterācijas izveides, lai tā būtu produkcijai gatava kā darba vietas mākoņa iepriekšējā versija. Bakalaura darba rezultātā tiks dokumentēts apsvērumu un instalācijas process, kāds tika veikts, lai sniegtos pēc bakalaura darbā izvirzītajiem mērķ…
IT treniņu uzdevumu veidošana
2018
Mākoņpakalpojumi sevī ietver daudz un dažādus virtuālos pakalpojumus. Viens no tiem ir virtuālās infrastruktūras veidošana, kur iespējams izveidot visdažādākās tīkla un virtuālo servisu sistēmas, kas ne tikai tiek īstenoti uzņēmumos, bet arī lieti noder datortīklu mācību apguvē. Darba mērķis ir izveidot IT treniņu uzdevumus jeb virtuālās laboratorijas, datortīklu apguvei laboratoriju izstrādes vidē. Darba gaitā ir iepazīta OpenStack orķestrēšanas komponentes Heat veidņu veidošana un apgūta virtuālo laboratoriju veidošana OpenStack vidē. Darba laikā tika izveidotas strādājošas virtuālās laboratorijas ar atšķirīgu to infrastruktūras sistēmu.
