- CLASSIFYING HIGH TECH NEW VENTURES BY PERFORMANCE: THE MARKET-TECHNOLOGICAL- ENTREPRENEURIAL MATRIX

This is an exploratory insight into the profile and prospects of growth and success attached to one category of firms, known as "New Technology Based Firms (NTBFs), the socalled high-tech and innovative new ventures. With this study we are willing to furnish a new methodological tool instrumental to position any firm characterised by being relatively recent and specialising in high-tech fields or at least, in activities with large scope for innovation. So, we intend to make a methodological contribution to theory in the entrepreneurship field, through an empirical exercise.Analysis of our empirically based data leads us to a new Matrix we call Market-Technology-Entrepreneurial Matrix, whose 8 three-dimensional quadrants serve to classify high- tech new ventures by performance. A Factorial Analysis coupled with a Discriminate Analysis are the statistical tools employed in obtaining the M-T-E Matrix and incorporating predictive capacity to it.

A recent exploratory insight on the profile of the innovative entrepreneur: Conclusions from a cross-tabs analysis

Despite growing concern towards entrepreneurship, the number of studies directly targeting the profile of the entrepreneur involved in innovative and high-tech new ventures are still scarce. This study, based on the empirical analysis of 18 highly innovative new ventures is focused on this category of entrepreneurs. Through the application of the statistical method known as the Cross-Tabs over a list of 31 variables defining the entrepreneur´s behavior and the new venture prospects we come up with a final profile of the innovative entrepreneur more likely to succeed in high-tech and highly innovative fields. A pesar del creciente interés de los analistas hacia la figura del emprendedor, el número de estudios orientados a estudiar el perfil del emprendedor innovador o emprendedor “high-tech” es todavía escaso. El presente estudio, basado en un análisis empírico sobre 18 compañías altamente innovadoras y de reciente constitución ubicadas en la zona conocida como la Bahía de San Francisco, apunta directamente sobre la mencionada categoría de emprendedor. A través de la aplicación del método estadístico Cros-Tab sobre una lista de 31 variables definitorias del comportamiento del emprendedor y las perspectivas de las compañías innovadoras nacientes, obtenemos finalmente un perfil del emprendedor innovador óptimo, capaz de gestionar adecuadamente nuevas empresas innovadoras.Emprendedor, innovación, perfil Entrepreneur, innovation, high-tech, profile

Modeling steep-slope flow across staggered emergent cylinders: application to fish passes

Designing efficient rock-ramp fish passes with flows over a bottom with roughness on the same scale as the water depth requires a precise knowledge of hydrodynamics in order to avoid or limit characteristics unattractive for fish, particularly for small fish. This paper considered the numerical modeling of free-surface flow across a steep-sloped ramp covered with staggered surface emergent cylinders. Considering the importance of complex flow features for fish passage, computational fluid dynamics (CFD) was adopted because it is capable of predicting such features. Because of the longitudinal periodicity of the arrangement of the obstacles, cyclic boundary conditions made this fine simulation possible. Two computational meshes (coarse and fine) and two turbulence models [shear stress transport (SST) k-ω and Smagorinsky large-eddy simulation (LES)] were used. The SST k-ω coarse mesh model gives correct time-averaged values, the main flow unstationarities and is usable for rock-ramp fish pass design, but a fine model using LES turbulence closure can provide detailed flow characteristics in the wakes in order to provide possible rest zones, particularly for smaller fish

A physically-based parsimonious hydrological model for flash floods in Mediterranean catchments

A spatially distributed hydrological model, dedicated to flood simulation, is developed on the basis of physical process representation (infiltration, overland flow, channel routing). Estimation of model parameters requires data concerning topography, soil properties, vegetation and land use. Four parameters are calibrated for the entire catchment using one flood event. Model sensitivity to individual parameters is assessed using Monte-Carlo simulations. Results of this sensitivity analysis with a criterion based on the Nash efficiency coefficient and the error of peak time and runoff are used to calibrate the model. This procedure is tested on the Gardon d'Anduze catchment, located in the Mediterranean zone of southern France. A first validation is conducted using three flood events with different hydrometeorological characteristics. This sensitivity analysis along with validation tests illustrates the predictive capability of the model and points out the possible improvements on the model's structure and parameterization for flash flood forecasting, especially in ungauged basins. Concerning the model structure, results show that water transfer through the subsurface zone also contributes to the hydrograph response to an extreme event, especially during the recession period. Maps of soil saturation emphasize the impact of rainfall and soil properties variability on these dynamics. Adding a subsurface flow component in the simulation also greatly impacts the spatial distribution of soil saturation and shows the importance of the drainage network. Measures of such distributed variables would help discriminating between different possible model structures

Is experience a useful resource for business model innovation?

[EN] Business model innovation has been proposed as a powerful strategic tool, able to offer competitive advantage, create markets and even reshape industries. Despite these powerful effects, little research has been conducted into studying and improving business model generation methods, and even less study has gone into analysing how to define new business models that can exert a disruptive effect on markets and industries. Our work tries to fill this gap, analysing whether experience encourages or discourages the generation of disruptive business models. An empirical analysis was carried out using an experimental methodology. The results seem to contradict the currently dominant Resource-Based View, but can be explained by the theory on inertia in organisations.Mateu Céspedes, JM.; March-Chorda, I. (2016). Is experience a useful resource for business model innovation?. Technology Analysis and Strategic Management. 28(10):1195-1209. doi:10.1080/09537325.2016.1182630S11951209281

Flow and drag force around a free surface piercing cylinder for environmental applications

This paper investigates flows around a free surface piercing cylinder with Froude number F<0.5 and Reynolds number around Re = 50,000. The aim of this work is to gain a better understanding of the flow behaviour in environmental systems such as fishways. The advances are based upon experimental and numerical results. Several flow discharges and slopes are tested to obtain both subcritical and supercritical flows. The drag force exerted on the cylinder is measured with the help of a torque gauge while the velocity field is obtained using particle velocimetry. For the numerical part, two URANS turbulence models are tested, the k-w SST and the RNG k-e models using the OpenFOAM software suite for subcritical cases, and then compared with the corresponding experimental results. With fishways applications in mind, the changes in drag coefficient Cd versus Froude number and water depth are studied and experimental correlations proposed. We conclude that the most suitable URANS turbulence model for reproducing this kind of flow is the k-w SST model

Session B5: 2D Modelling of Nature-Like Fish Passes

Abstract: The passability of nature-like fishpass depends on water depth, velocity and kinetic turbulent energy. To estimate these values the 2D Saint Venant code can be an interesting tool because it can simulate a large range of geometrical configuration and also take into account the deformation of the free surface. However the flow in a fish pass can reach the limit of the model assumptions as the hydrostatic pressure. As a consequence a series of experiments on down-scale are conducted to validate the numerical results. Velocity and turbulent fields are measured by Acoustic Doppler Velocimeter (ADV) for five combinations of discharge and slope. The comparison between experiments and model shows that the numerical results are relevant for a moderate Froude number which corresponds to fishpass application. Moreover, some crucial data related to passability are extracted from the computation as the maximum velocity location

Écoulements au-dessus de macro-rugosités artificielles constituées de plots

Les écoulements au-dessus de macro-rugosités, dans lesquels les dimensions des éléments rugueux sont du même ordre de grandeur que les profondeurs des écoulements, trouvent de nombreuses applications dans l'hydraulique environnementale, en particulier dans les dispositifs de franchissement des obstacles pour les poissons migrateurs. Cet article présente une synthèse des résultats expérimentaux acquis lors d'essais en canal vitré menés à l'Institut de Mécanique des Fluides de Toulouse, en utilisant comme rugosités des rangées de plots cylindriques. Après une description des écoulements observés, on examine l'influence des différents paramètres. Des relations liant le débit à la pente, à la submersion relative, à la porosité transversale et à l'écartement longitudinal sont proposées. Les profils verticaux des vitesses sont présentés. Les résultats sont discutés dans une perspective piscicole et un exemple d'application dimensionnelle relative au franchissement des poissons est présenté
