Kvantifisering av intensitetsfordeling hos fotballspillerepå høyt norsk nivå
2009
Masteroppgave i idrettsvitenskap Universitetet i Agder 2009 Denne studien hadde som hensikt å kvantifisere den daglige intensitetsdistribusjonen til en gruppe profesjonelle fotballspillere basert på tre ulike kvantifiseringsmetoder. Hensikten var også å kartlegge treningsmessige forskjeller i oppkjøringsfase og sesong. Metode: femten mannlige fotballspillere (Alder: 24,1 ± 5,2) gjennomførte en løpstest på tredemølle til utmattelse, for å finne VO2 og hjertefrekvensverdier som korresponderte med ventilatoriske terskler (VT1 og VT2), maksimalt oksygenopptak (VO2maks 58 ± 3) og makspuls. VT1 og VT2 ble brukt for å dele inn tre intensitetssoner med bakgrunn i hjertefrekvens. Treningsdata ble in…
Overgangen fra 7-er til 11-er fotball : fra lek til alvor?
2012
Masteroppgave i idrettsvitenskap -Universitetet i Agder 2012 Det debatteres jevnlig om vi er gode nok på spillerutvikling i Norge, og mye kan trolig bli bedre. Denne studien tar for seg den tilsynelatende uproblematiske overgangen fra 7-er til 11-er fotball, men som viser seg å representere er et skille fra lek til alvor. Studien undersøker ulike aspekter overgangen fører med seg og om disse er hensiktsmessig for utvikling av unge spillere, eller om de kan ha en negativ effekt som fører til lav motivasjon og frafall av spillere. Studien er todelt; - Studie 1 er en kvantitativ observasjons-studie hvor det ble sett på antall involveringer i både 7-er og 11-er fotball hos 40 13-åringer i Agder…
El secano mejorado y la agricultura aterrazada. Paisajes significativos con un gran valor socio-ambiental y didáctico
2019
En los últimos veinte años, en las denominadas sociedades postproductivistas se ha producido un redescubrimiento del paisaje asociado a su identificación como un elemento identitario y de calidad. En la provincia de Alicante, representativos resultan el denominado secano mejorado (aprovechamiento de turbias) característico de la comarca de l’Alacantí y los paisajes aterrazados (Montaña de Alicante). Los objetivos de esta investigación son: 1) Analizar la ordenación tradicional de los paisajes derivados del uso de turbias y los aterrazados; 2) Analizar las estrategias de adaptación al medio y cómo el proceso de abandono ha repercutido ambientalmente en el área de estudio; 3) Poner de manifie…
Pedagogical experiments with MathCheck in university teaching
2019
MathCheck is a relatively new online tool that gives students feedback on their solutions to elementary university mathematics and theoretical computer science exercises. MathCheck was designed with constructivism learning theory in mind and it differs from other online tools as it checks the solutions step by step and shows a counter-example if the step is incorrect. It has been in student use since the autumn of 2015 and under design-based research from the first online day. The main research questions of this study are the following. 1) How can the usage of MathCheck support the aspects of conceptual understanding and procedural fluency of constructivism learning? 2) How can MathCheck em…
POSTER: Optimizing scientific file I/O patterns using advice based knowledge
2014
Before us, other works have used data prefetching to boost applications performance [1]–[8]. Our approach differs from these works since we do not rely on precise I/O pattern information to predict and prefetch every chunck of data in advance. Instead we use data prefetching to group many small requests in a few big ones, improving applications performance and utilization of the whole storage system. Moreover, we provide the infrastructure that enables users to access file system specific interfaces for guided I/O without modifying applications and hiding the intrinsic complexity that such interfaces introduce.
Improving Web Prefetching by Making Predictions at Prefetch
2007
Most of the research attempts to improve Web prefetching techniques have focused on the prediction algorithm with the objective of increasing its precision or, in the best case, to reduce the user's perceived latency. In contrast, to improve prefetching performance, this work concentrates in the prefetching engine and proposes the Prediction at Prefetch (P@P) technique. This paper explains how a prefetching technique can be extended to include our P@P proposal on real world conditions without changes in the web architecture or HTTP protocol. To show how this proposal can improve prefetching performance an extensive performance evaluation study has been done and the results show that P@P can…
Architectural improvements and FPGA implementation of a multimodel neuroprocessor
2003
Since neural networks (NNs) require an enormous amount of learning time, various kinds of dedicated parallel computers have been developed. In the paper a 2-D systolic array (SA) of dedicated processing elements (PEs) also called systolic cells (SCs) is presented as the heart of a multimodel neural-network accelerator. The instruction set of the SA allows the implementation of several neural algorithms, including error back propagation and a self organizing feature map algorithm. Several special architectural facilities are presented in the paper in order to improve the 2-D SA performance. A swapping mechanism of the weight matrix allows the implementation of NNs larger than 2-D SA. A systo…
LightSpMV: Faster CSR-based sparse matrix-vector multiplication on CUDA-enabled GPUs
2015
Compressed sparse row (CSR) is a frequently used format for sparse matrix storage. However, the state-of-the-art CSR-based sparse matrix-vector multiplication (SpMV) implementations on CUDA-enabled GPUs do not exhibit very high efficiency. This has motivated the development of some alternative storage formats for GPU computing. Unfortunately, these alternatives are incompatible with most CPU-centric programs and require dynamic conversion from CSR at runtime, thus incurring significant computational and storage overheads. We present LightSpMV, a novel CUDA-compatible SpMV algorithm using the standard CSR format, which achieves high speed by benefiting from the fine-grained dynamic distribut…
Bit-Parallel Approximate Pattern Matching on the Xeon Phi Coprocessor
2014
Bit-parallel pattern matching encodes calculated values in bit arrays. This approach gains its efficiency by performing multiple updates within a machine word. An important parameter is therefore the machine word size (e.g. 32 or 64 bits). With the increasing length of vector registers, the efficient mapping of bit-parallel pattern matching algorithms onto modern high performance computing architectures is becoming increasingly important. In this paper, we investigate an efficient implementation of the Wu-Manber approximate pattern matching algorithm on the Intel Xeon Phi coprocessor. This architecture features a 512-bit long vector processing unit (VPU) as well as a large number of process…
Design methods of multithreaded architectures for multicore microcontrollers
2011
The development of electronic technology today has allowed the implementation of complex architectures, which led to the emergence of multicore processors technology. Multicore architectures are built from superscalar and multithreaded processors. Integrating new technologies in embedded applications requires the development of multicore processors that can be integrated into a smaller area like a classic microcontroller. These processors must manage fewer resources and be able to manage multiple tasks simultaneously. In this paper we present a method of modeling, simulation and evaluation of two multithreaded architectures with limited resources, which could be integrated into embedded sys…
