An International Survey of Quality and Safety Programs in Radiology

2021

Purpose: The aim of this study was to determine the status of radiology quality improvement programs in a variety of selected nations worldwide. Methods: A survey was developed by select members of the International Economics Committee of the American College of Radiology on quality programs and was distributed to committee members. Members responded on behalf of their country. The 51-question survey asked about 12 different quality initiatives which were grouped into 4 themes: departments, users, equipment, and outcomes. Respondents reported whether a designated type of quality initiative was used in their country and answered subsequent questions further characterizing it. Results: The re…

Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application

2021

This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…

Evaluation and Self-Evaluation in Simultaneous Translation: Assessments Methods

2012

Abstract The nature of evaluation and self-evaluation in simultaneous interpretation is based on the close connection between the main text (the version proposed by the speaker) and the interpreter's version. Between these two elements a number of variables emerge, that can damage the efficiency and the accuracy of simultaneous interpretation. The intention of our study is to propose a set of scientific methods and tools in order to offer to the interpreter the possibility of a self-assessment and the benefit of an appropriate evaluation of his work. In order to achieve these goals we used several methods, including experiments, case studies, questionnaires, evaluation scales. Research subj…

Pilotażowe badania sensoryczne autorskich receptur preparatów kosmetycznych z zawartością śluzu ślimaka

2017

Od wielu lat ślimaki lądowe rodzaju Helicidae pełnią rolę luksusowego surowca spożywczego. Ich spożycie oscylujące wokół 40 tysięcy ton rocznie co dało początek idei hodowli fermowych ślimaków lądowych. Pojawił się również pomysł wykorzystania ich wydzieliny w produktach kosmetycznych o działaniu leczniczo-upiększającym. Śluz ze ślimaka wykazuje, m.in. właściwości: regenerujące, ochronne, przeciwzapalne, nawilżające, zwiększające elastyczność skóry. Celem pracy była analiza jakości sensorycznej autorskich receptur preparatów kosmetycznych zawierających śluz ze ślimaka. Badania sensoryczne odgrywają ważną rolę przy opracowywaniu nowopowstałych receptur preparatów kosmetycznych oraz w potwier…

How to get things done in social virtual reality : A study of team cohesion in social virtual reality–enabled teams

2022

Social virtual reality (SVR) enables teams to operate in a virtual environment that simulates and enhances real-world interactions. However, there is an absence of empirical analysis of how SVR can affect the performance of virtual teams. This paper documents how SVR affects the formation of team cohesion (i.e., task cohesion and social cohesion), which is a critical success factor for team performance. To address this gap in the research, we conducted a qualitative study by interviewing 20 members from virtual teams assigned to perform a challenging collaborative task in SVR. As a contribution, our study identifies five primary affordances and 11 sub-affordances for team cohesion in SVR. W…

Does technical risk dialogue entail socioeconomic valuation? : The case of scientific dispute over copper corrosion in a spent nuclear fuel disposal …

2016

Among the proponents of nuclear power, the project for the safe and secure disposal of spent nuclear fuel (SNF) in Finland is often deemed as a success story. Opponents have had difficulties getting publicity for their claims about the risks of the project. Their most powerful arguments have been mostly ethical, but on technical issues the opponents have been in a weaker position than the proponents. However, recently the risk of corrosion in oxygen-free water has become subject to scientific controversy, possibly threatening even the realisation of the final disposal of spent nuclear fuel. In Sweden, this issue has been intensively debated since 2007, but only recently has this debate take…

Criteria for the evaluation of requirements management tools supporting distributed software product line engineering and management

2015

The development of software product lines (SPL) by geographically distributed teams increases the complexity of requirements management (RM) related tasks, making the support of a RM tool necessary. However, the selection of the most appropriate RM tool can be challenging, therefore the use of a comprehensive criteria list guiding the selection becomes essential. The goal of this research is to determine whether available criteria lists include comprehensive criteria for the evaluation of RM tools to be adopted in distributed SPL requirements management. This research answers the following research questions: (1) Do currently available criteria lists for RM tool evaluation allow the assessm…

Medical Software Needs Calm Compliance

2022

The promise of calm computing, a concept introduced by Mark Weiser more than 20 years ago, has been mostly realized today. For instance, as an end user, you expect to interact during your daily routine with a multitude of sophisticated services and applications without being aware of their technical implementation. All you need is a smartphone and an always-on Internet connection. peerReviewed

Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
