This overview of the uses of sodars in meteorological applications categorizes the applications by signal source, specifically amplitude, frequency, or “visualization” for example, of vertical time sections of signal amplitude. Examples are shown of data derived from each category. A final section presents the potential for using groups of sodars in networks with other instruments to estimate q...

Physicians should be aware of possible anatomical variants during cannulation for extracorporeal membrane oxygenation (ECMO). Particular attention to ensure continual visualization of the guidewire before proceeding to final positioning of the ECMO cannulae should be paid. Alternative imaging modalities should be contemplated when uncertainties arise to minimize the risk of inadvertent vascular...

We present the usage of a non-discrete degree of interest (DOI) function, obtained by brushing multi-valued 3D simulation data in information visualization views, to define opacity, color, and geometrical transfer functions for 3D rendering in a scientific visualization view via linking. To reflect the smooth nature of features in flow simulation data, smooth brushing was chosen. Different avai...

In this paper, we propose advanced prototype machines (APMs). APMs model classes as small sets of highly descriptive prototypes which are well suited for interactive visualization. Thus, APMs offer a method to analyze class models, feature spaces and particular classification scenarios. To derive the prototypes, we introduce ”Push and Grow”, a classification algorithm which is based on a qualit...

This paper studies observable and irrevocable commitment in bargaining. We investigate when commitment tactics can cause an impasse and when compromise is feasible. In the static model in which a player’s commitment decision is made simultaneously with his choice of bargaining stance, compromise becomes unattainable (Ellingsen and Miettinen, 2008). We first analyze a static bargaining model, in...

Creating valid and reliable classroom tests are very important to an instructor for assessing student performance, achievement and success in the class. The same principle applies to the State Exit and Classroom Exams conducted by the instructors, state and other agencies. One powerful technique available to the instructors for the guidance and improvement of instruction is the test item analys...

This work describes the impact of different teachers’ approaches in using Moodle, for supporting their courses, at the Polytechnic of Porto School of Engineering. The study covers five different courses, from different degrees and different years, and includes a number of Moodle resources especially supporting laboratory classes. These and other active resources are particularly analyzed in ord...

Gamification, the application of game elements to non-game settings, continues to grow in popularity as a method to increase student engagement in the classroom. We tested students across two courses, measuring their motivation, social comparison, effort, satisfaction, learner empowerment, and academic performance at four points during a 16-week semester. One course received a gamified curricul...
