Strategic Decisions in Task-Oriented Reading.
2015
AbstractAnswering questions from texts are assessment and instructional activities that are frequently used in schools. Nevertheless, little is known about the strategic processes that students take while performing these tasks. We explored the amount and frequency that students initially read of a text before they answered questions pertaining to the material. In a procedure similar to the one used in the PISA (Program for International Students Assessment), one-hundred-seventy students between 7thand 9thgrade read and answered several questions designed to assess task-oriented reading in three specific texts. We recorded on-line indexes that evaluated student behavior (e.g., the amount of…
Analysis of ultra-triathlon performances
2011
Romuald Lepers1, Beat Knechtle2,3, Patrizia Knechtle2, Thomas Rosemann2 1INSERM U887, Faculty of Sport Sciences, University of Burgundy, Dijon, France; 2Institute of General Practice and Health Services Research, University of Zurich, Switzerland; 3Gesundheitszentrum St Gallen, St Gallen, Switzerland Abstract: Despite increased interest in ultra-endurance events, little research has examined ultra-triathlon performance. The aims of this study were: (i) to compare swimming, cycling, running, and overall performances in three ultra-distance triathlons, double Ironman distance triathlon (2IMT) (7.6 km swimming, 360 km cycling, and 84.4 km running), triple Ironman distance triathlon (3IMT) (11.…
Extending SSD lifetime in database applications with page overwrites
2013
Flash-based Solid State Disks (SSDs) have been a great success story over the last years and are widely used in embedded systems, servers, and laptops.One often overlooked ability of NAND flash is that flash pages can be overwritten in certain circumstances. This can be used to decrease wear out and increase performance.In this paper, we analyze the potential of overwrites for the most used data structure in database applications: the B-Tree. We show that with overwrites it is possible to significantly reduce flash wear out and increase overall performance.
Analysis of multiple intelligences and creativity in university students
2018
espanolResumen: Un reto de la educacion actual es formar a alumnos competentes para desenvolverse en una sociedad diversa y dinamica. El cociente intelectual no es suficiente para garantizar el exito academico ni profesional (Extremera & Fernandez-Berrocal, 2006) y deben considerarse aspectos cognitivos, sociales y emocionales. El objetivo del estudio fue analizar el grado alcanzado en estudiantes universitarios de trabajo social en las inteligencias multiples, inteligencia emocional, creatividad y rendimiento academico, asi como su relacion y las diferencias en funcion del sexo y el curso en una muestra de 100 estudiantes. Se encontraron diferencias significativas en funcion del curso y re…
Evaluating Bluetooth Performance as the Support for Context-Aware Applications
2005
We present an experiment relative to the use of the Bluetooth wireless technology to provide network support for context-aware applications. We describe an approach to provide network interconnection using a combination of wireless and wired network technologies. We also describe the steps taken to create a Bluetooth based context-aware application. We, finally, evaluate, using a small test-bed and simulation the overall performance of this technology when adopted in the area of context-aware and ubiquitous computing.
Mountain dairy wastewater treatment with the use of a 'irregularly shaped' constructed wetland (Aosta Valley, Italy)
2014
Abstract In mountain areas, economical activities related to milk processing represent both a key source of income and job opportunities. One of the main characteristics of cheese production is the seasonal variability in the volume of milk processed and wastewater production that tend to limit the capacity of ecosystems to absorb their inputs. In alpine environment, the scarcity of plain surfaces and the climatic conditions results in the need for high CW performances of variable nutrient inputs in different seasons. By evaluating a CW seasonal efficiency for dairy wastewaters in a mountain region (Aosta Valley-NW Italy), this research was aimed to understand how performances of nutrient r…
UnipaBCI a novel general software framework for brain computer interface
2017
The increasing interest in Brain Computer Interface (BCI) requires new fast, reliable and scalable frameworks that can be used by researchers to develop BCI based high performance applications in efficient and fast ways. In this paper is presented "UnipaBCI", a general software framework for BCI applications based on electroencephalogra-phy (EEG) that can fulfill these new needs. A visual evoked potentials (VEP) application has also been developed using the proposed framework in order to test the modular architecture and the overall performance. Different types of users (beginners and experts in BCI) have been involved during the "UnipaBCI" experimental test and they have exhibited good and…
Pair potential calculation of molecular associations: a vectorized version
1991
Abstract The program AMYRVF is a vectorized and largely modified version of a previous program called AMYR for calculating molecular associations by means of Fraga's pair-wise atom-atom potential. Three new minimization procedures have been implemented as well as other improvements such as the inclusion of new pair-wise dispersion energy terms with damping functions, and the calculation of topological indices. Benchmark tests have been carried out on an IBM 3090 150E VF; the timings for the new vector algorithms and for the standard scalar computations, as well as the dependence of the overall performance gain on the size of interacting systems are reported for the VS Fortran 2.4 compiler e…
Decomposition analysis of bioresources: Implementing a competitive and sustainable bioeconomy strategy in the Baltic Sea Region
2021
Bioeconomy development has become one of the new trends in policy design and research. This study looks at biotic resource extraction in the Baltic Sea region countries providing detailed country by country analyses of factors affecting changes in resource extraction. The study is based on the index decomposition analysis including factors related to bioeconomy strategies such as the population, share of people employed in bioeconomy, labour intensity, biotic resource extraction productivity, share of bioeconomy, export intensity, and share of bioresource export. The main factors increasing biotic resource extraction were the growth in labour material intensity, biotic extraction productivi…
Constructal law optimization of a boiler
2017
The paper aims at the optimization of the design of a biomass boiler under the inspiration of the Constructal Law by Bejan. The boiler is of the smoke tubes typology, fuel being biomass pellets. The smoke tubes are 16 and are placed in a staggered configuration. A model is built in MATLAB environment, based on empirical correlations and the mean log temperature methodology. The analysis is based on the development of a wide parametric analysis that involves variations of diameters, numbers and positioning of the tubes. Results are based on the concept of the overall performance coefficient methodology and investigate both the pressure drops variation and the thermal power generated in the d…
