Non-branching geodesics and optimal maps in strong CD(K,∞) -spaces

2014

We prove that in metric measure spaces where the entropy functional is Kconvex along every Wasserstein geodesic any optimal transport between two absolutely continuous measures with finite second moments lives on a non-branching set of geodesics. As a corollary we obtain that in these spaces there exists only one optimal transport plan between any two absolutely continuous measures with finite second moments and this plan is given by a map. The results are applicable in metric measure spaces having Riemannian Ricci curvature bounded below, and in particular they hold also for Gromov-Hausdorff limits of Riemannian manifolds with Ricci curvature bounded from below by some constant. peerReview…

Localization of Multi-Class On-Road and Aerial Targets Using mmWave FMCW Radar

2021

mmWave radars play a vital role in autonomous systems, such as unmanned aerial vehicles (UAVs), unmanned surface vehicles (USVs), ground station control and monitoring systems. The challenging task when using mmWave radars is to estimate the accurate angle of arrival (AoA) of the targets, due to the limited number of receivers. In this paper, we present a novel AoA estimation technique, using mmWave FMCW radars operating in the frequency range 77–81 GHz by utilizing the mechanical rotation. Rotating the radar also increases the field of view in both azimuth and elevation. The proposed method estimates the AoA of the targets, using only a single transmitter and receiver. The measurements are…

Validation and Extension of the Usability Heuristics for Mobile Map Applications

2016

Heuristic usability evaluation is light but efficient method for finding usability problems. In this paper, we report the process of validation and further development of the previously introduced usability heuristics for mobile map applications. The validation began by testing the heuristics by 58 evaluators who used them for usability evaluation of four different map applications. The evaluators also filled a questionnaire about the understandability of the heuristics. The amount, severity and quality of the problems found with the heuristics were reviewed and the heuristics’ understandability analyzed. As a result, it was shown that the heuristics were efficient for finding usability pro…

Orientation Aids for Mobile Maps

2015

Using mobile maps to represent urban, work, or entertainment environments offers new possibilities to plan and carry out tasks. One potentially critical problem in mobile map usage is the misalignment between the user's frame of reference and the frame of reference of the map. In the experiment reported here, three different ‘orientation aids’ were tested in the context of restricted space, such as a large factory hall. The aim of the study was to find out how user interface design can help the user mentally align misaligned frames of reference for efficient mobile map use. The results of the experiment (N = 12) suggest using a ‘you are here’ marker and landmark highlighting, while canonica…

Lost or not? : designing and evaluating user interfaces of mobile map services : the viewpoint of supporting users' location awareness

2016

The motivation for this thesis arose from the problem of people getting lost, both with and without mobile maps. I will answer a primary research question: 1) How can we support users’ location awareness with mobile map applications? As an ad-dition to this, I have the following sub-questions: a) Why do people get lost even when using a mobile map application? b) What are the best practices to support navigation? c) How can we research what the important objects in the natural environment are that should be emphasized in mobile maps? d) How do we prevent the user from focusing on the map service at the expense of perceiving the location in the real environment? e) What would a good mobile m…

Modelo de conglomerados para el análisis bayesiano de datos epidemiológicos en áreas pequeñas

2016

Uno de los principales objetivos del mapeo de la enfermedad es describir la variación espacial del riesgo de una enfermedad, para evaluar y cuantificar la cantidad de la verdadera heterogeneidad espacial y los patrones de riesgos asociados (Lawson, 2009). La mayoría de los modelos propuestos en la literatura proporcionan riesgos relativos estimados en áreas pequeñas teniendo en cuenta la estructura de vecindad, por lo que las áreas vecinas tienen riesgos similares, uno de los modelos más populares es el modelo de convolución (Besag et al., 1991). Sin embargo, hay situaciones en que esta suposición puede no ser apropiada. Estudios recientes en este ámbito son capaces de explorar con precisió…

Readers’ Theater Projects for Special Education : A Randomized Controlled Study

2022

A randomized controlled trial was conducted to study the effectiveness of two readers’ theater (RT) programs in promoting reading skills and motivation of dysfluent readers in Grades 3–4. One program (RT Goal) included a goal of preparing a performance for an audience (n = 50), while another program (RT Practice) did not include such a goal (n = 49). A group of dysfluent readers receiving traditional oral reading intervention (Control group; n = 59) and a group of classroom peers (Mainstream group; n = 159) served as controls. The results indicate that both RT groups and the Control group developed at a higher rate in oral reading speed during the intervention period than the Mainstream gro…

The relationships among motivational climate, perceived competence, physical performance, and affects during physical education fitness testing lesso…

2021

Despite the prominence of fitness testing in school physical education (PE), there is a sparsity of research examining the antecedents of students’ affective experiences during fitness testing lessons. This study aimed to investigate the associations among task- and ego-involving motivational climates, perceived physical competence, physical performance, enjoyment, and anxiety during two different types of PE fitness testing lessons. Altogether, 645 Finnish students from Grade 5 (50% boys, Mage = 11.2, SD = 0.36) and Grade 8 (47% boys, Mage = 14.2, SD = 0.35) participated in two fitness testing lessons with different content (lesson 1: 20-meter shuttle run test and a test of flexibility; l…
