Juan Valdez: Resurgimiento de una marca

La Federación Nacional de Cafeteros fue fundada en el año 1927 con el objetivo de elevar el nivel de vida de los caficultores y dar a conocer la calidad del café Colombiano en el mundo. Parte del trabajo de la federación ha sido el posicionamiento a nivel mundial del café Colombiano, para lo cual ha utilizado varias campañas publicitarias entre las cuales se destaca la creación en el año 1959 del icono Juan Valdez con su mula Conchita. Así mismo, en noviembre del año 2002 la Federación Nacional de Cafeteros creó la empresa Procafecol S.A. con el objetivo de generar negocios de valor agregado para los cafeteros y desarrollar las actividades empresariales bajo la marca Juan Valdez Café. En el año 2005 Procafecol S.A. inició el proceso de expansión internacional, para el año 2013 la compañía reportaba utilidades alrededor de los cuatro mil millones de pesos colombianos y excelentes cifras de expansión. Sin embargo, desde la apertura de la primera tienda Juan Valdez en el año 2002 la marca generaba pérdidas, que alcanzaron aproximadamente diecinueve mil millones de pesos colombianos en el año 2012. (Procafecol S.A., 2013) Teniendo en cuenta que es necesario tener herramientas que permitan generar estrategias desde la dirección y gerencia para asegurar la perdurabilidad en las empresas, adscrito al GIPE (Grupo de Investigación en Perdurabilidad Empresarial), se realizó este estudio de caso como parte de la línea de investigación de Realidad empresarial. Con el fin de analizar el caso de Procafecol S.A. y su marca Juan Valdez, e ilustrar el resurgimiento de la compañía después de 9 años de presentar pérdidas en el ejercicio financiero.

Captain Jones and the ghost ship.

El capitan Jones y su tripulación son los piratas más fracasados que navegan por los siete mares. Cuando encuentran un barco abandonado cargado de tesoros piensan en su buena suerte. Pero, no se dan cuenta de que han saqueado un barco fantasma.

The ship as symbol in the prehistory of Scandinavia and south-east Asia

The ship is the dominant element in the visual culture of the South Scandinavian Bronze Age, appearing in several different media, including rock carvings, decorated metalwork and above-ground monuments. Discussion has divided between those scholars who interpret this imagery in terms of long-distance exchange networks and those who emphasize its more local significance, including its deployment in mortuary ritual. A strikingly similar system is identified in Southeast Asia and part of Melanesia and can be interpreted through archaeological and ethnographic sources, but in this case there is no need to distinguish between 'practical' and 'symbolic' interpretations of the depictions of ships. This paper summarizes the evidence from this region and suggests that it can offer a fruitful source of comparison for archaeologists working in northern Europe.

An FLIR video surveillance system to avoid bridge-ship collision

In this paper, a forward-looking infrared (FLIR) video surveillance system is presented for collision avoidance of moving ships to bridge piers. An image pre-processing algorithm is proposed to reduce clutter noises by multi-scale fractal analysis, in which the blanket method is used for fractal feature computation. Then, the moving ship detection algorithm is developed from image differentials of the fractal feature in the region of surveillance between regularly interval frames. Experimental results have shown that the approach is feasible and effective. It has achieved real-time and reliable alert to avoid collisions of moving ships to bridge piers

A bridge-ship collision avoidance system based on FLIR image sequences

In this paper, a forward-looking infrared (FLIR) video surveillance system is presented for collision avoidance of moving ships to bridge piers. An image preprocessing algorithm is proposed to reduce clutter background by multi-scale fractal analysis, in which the blanket method is used for fractal feature computation. Then, the moving ship detection algorithm is developed from image differentials of the fractal feature in the region of surveillance between regularly interval frames. When the moving ships are detected in region of surveillance, the device for safety alert is triggered. Experimental results have shown that the approach is feasible and effective. It has achieved real-time and reliable alert to avoid collisions of moving ships to bridge piers.

Autonomous ship collision free trajectory navigation and control algorithms

A new autonomous ship collision free (ASCF) trajectory navigation and control system has been introduced with a new recursive navigation algorithm based on analytic geometry and convex set theory for ship collision free guidance. The underlying assumption is that the geometric information of ship environment is available in the form of a polygon shaped free space, which may be easily generated from a 2D image or plots relating to physical hazards or other constraints such as collision avoidance regulations. The navigation command is given as a heading command sequence based on generating a way point which falls within a small neighborhood of the current position, and the sequence of the way points along the trajectory are guaranteed to lie within a bounded obstacle free region using convex set theory. A neurofuzzy network predictor which in practice uses only observed input/output data generated by on board sensors or external sensors (or a sensor fusion algorithm), based on using rudder deflection angle for the control of ship heading angle, is utilised in the simulation of an ESSO 190000 dwt tanker model to demonstrate the effectiveness of the system.

Propagation of ship waves on a sloping bottom

The numerical model FUNWAVE was adapted in order to simulate the generation and propagation of ship waves to shore, including phenomena such as refraction, diffraction, currents and breaking of waves. Results are shown for Froude numbers equal to 0.8, 1.0 and 1.1, in order to verify the refraction of the wave pattern, identify breaking conditions and to investigate the wave generation scheme as a moving pressure at the free surface. © 2009 World Scientific Publishing Co.
