Internal Factors in Professional Service Firms (PSFs) and their Impact on Innovation Output : A Quantitative Study of Norwegian PSFs
2017
Master's thesis Business Administration BE501 - University of Agder 2017 The purpose of this study is to contribute to the understanding of Norwegian Professional Service Firms (PSFs) by exploring the effect of internal factors’ impact on innovation output. The four internal factors selected for this study are (1) organizational inertia, (2) training, (3) human capital and (4) innovation culture. The economy is becoming increasingly knowledge based, and at the same time, the importance of innovation is becoming more prevalent in the business world. Even among PSFs, that are perceived as conservative, innovation is now becoming critical for survival. However, it is challenge to become a succ…
Análisis de género, productividad científica y colaboración de las profesoras universitarias de Ciencias de la Salud en la Comunidad Valenciana (2003…
2010
[EN] The article presents an analysis of the scholarly output of female professors in the fi eld of Health Science in the Autonomous Region of Valencia from 2003 to 2007,through bibliometric techniques and the application of a gender variable. The work attempted to identify how many women became large producers of scholarly articles compared to those who did not reach the same levels of productivity and impact. A total of 3,739 articles were retrieved during this period and the gender of all authors with more than 2 articles was identifi ed. Of these authors 2,774 (60.41 %) were male and 1,818 (39.59 %) were female. Focusing solely on large producers, the percentage of women publishing more…
PV modules with variable ideality factors
2012
The classical single-exponential I–V curve model for crystalline-Si PV devices assumes a constant ideality factor. The model is widely applied in e.g. modeling the power output of PV systems at different irradiances and temperatures, and also in calculating the Equivalent Cell Temperature (ECT) from the open-circuit voltage. The present paper presents results from several crystalline-Si (c-Si) module types suggesting that the ideality factor may change with irradiance. The possible implications of such variability are discussed, in particular the need for a new ECT calculation procedure as well as for revision of some PV performance models.
How costly are debt crises?
2011
The aim of this paper is to assess the short- and medium-term impact of debt crises on GDP. Using an unbalanced panel of 154 countries from 1970 to 2008, the paper shows that debt crises produce significant and long-lasting output losses, reducing output by about 10 percent after eight years. The results also suggest that debt crises tend to be more detrimental than banking and currency crises. The significance of the results is robust to different specifications, identification and endogeneity checks, and datasets.
Verification of Numerical Weather Prediction Model Results for Energy Applications in Latvia
2014
Abstract Wind power forecasting greatly relies on wind speed forecasts. Numerical Weather Prediction (NWP) models are a reliable source of meteorological forecasts and they can also be used in wind resource assessment. In this work we carry out the verification of wind speed results from the NWP model Weather Research and Forecast (WRF), grid resolution - 3 km. Results from 172 model runs in May and November 2013 are compared with meteorological observations in 24 stations in Latvia. The model usually predicts wind speed values that are larger than the observed and the diurnal cycle has a large impact on verification results. Verification results obtained by interpolating model results betw…
Optimal passive-damping design using a decentralized velocity-feedback H-infinity approach
2012
In this work, a new strategy to design passive energy dissipation systems for vibration control of large structures is presented. The method is based on the equivalence between passive damping systems and fully decentralized static velocity-feedback controllers. This equivalence allows to take advantage of recent developments in static output-feedback control design to formulate the passive-damping design as a single optimization problem with Linear Matrix Inequality constraints. To illustrate the application of the proposed methodology, a passive damping system is designed for the seismic protection of a five-story building with excellent results. Peer Reviewed
Seasonal reproducibility and predictability of the West African Monsoon in coupled GCMs
2009
In the framework of the ENSEMBLES FP6 project, an ensemble prediction system based on five different state-of-the-art European coupled models has been developed. This study evaluates the performance of these models for forecasting the West African monsoon (WAM) at the monthly time scale. From simulations started the 1 May of each year and covering the period 1991–2001, the reproducibility and potential predictability (PP) of key parameters of the WAM—rainfall, zonal and meridional wind at four levels from the surface to 200 hPa, and specific humidity, from July to September—are assessed. The Sahelian rainfall mode of variability is not accurately reproduced contrary to the Guinean rainfall …

AUGMENTATIVE AND ALTERNATIVE COMMUNICATION (AAC) IN NEURODEVELOPMENTAL DISORDERS: A MINIREVIEW
2018
Children with neurodevelopmental disorders such as Autism Spectrum Disorders (ASD), cerebral palsy or severe motor speech disorders may beneficiate of augmentative and alternative communication (AAC) systems that may improve the developing language and the communication abilities. The term AAC tend to include each form of communication supplementing or replacing the natural speech production.
Multi-Antenna Covert Communication With Jamming in the Presence of a Mobile Warden
2021
Covert communication can hide the information transmission process from the warden to prevent adversarial eavesdropping. However, it becomes challenging when the warden can move. In this paper, we propose a covert communication scheme against a mobile warden, which maximizes the connectivity throughput between a multi-antenna transmitter and a full-duplex jamming receiver with the covert outage probability (COP) limit. First, we analyze the monotonicity of the COP to obtain the optimal location the warden can move. Then, under this worst situation, we optimize the transmission rate, the transmit power and the jamming power of covert communication to maximize the connection throughput. This …
