Apoyo a la construcción de un software de soporte a decisiones concernientes al comercio entre Colombia y Estados Unidos

La entrada en vigor del Tratado de Libre Comercio (TLC) con Estados Unidos representa para los empresarios colombianos la oportunidad de acceder al mercado más importante del mundo en una posición privilegiada, bajo la cual resulta más sencilla la colocación de productos en este pais para aquellas compañías con vocación exportadora. Sin embargo, la alta competencia y desarrollo de este mercado hace necesario que las empresas cuenten con información apropiada que les permita enfocar sus esfuerzos en productos, segmentos de mercado o Estados específicos donde puedan alcanzar la sostenibilidad y perdurabilidad en el tiempo, así como el desarrollo de nuevas posibilidades comerciales. Para tal fin, realizamos este trabajo de investigación con el cual se busca generar una herramienta informática que contenga información respecto al flujo comercial de Colombia hacia cada uno de los 50 estados de EE.UU., detallando en cada caso las oportunidades comerciales identificadas por partidas arancelarias; y que servirá de apoyo para aquellos empresarios colombianos que buscan beneficiarse de la nueva coyuntura comercial que ofrece el acuerdo bilateral.

Innovación de un nuevo sistema de gestión empresarial aplicación e implementación nuevo software a nivel nacional METROKIA S.A.

Kia Motors Corporation (KMC) tiene como objetivo desde hace algunos años, la creación e implementación de una solución de negocios enfocada en una gestión empresarial estandarizada a todos los distribuidores de Kia a nivel latinoamericano: Colombia, Perú, Ecuador y Chile. El proceso actual con el que cuentan los distribuidores en América Latina con sus concesionarios es enviar toda la información relacionada con los estatutos financieros a través de correo electrónico junto con una base de datos física, la cual se va archivando. El proceso es manual siendo de mucha dedicación y tiempo requerido para cumplir con las funciones pedidas. El enfoque actual de este proceso es claro: analizar el desempeño y rendimiento de cada uno de los concesionarios de la red junto con la identificación de oportunidades para mejorar. KMC junto con todos sus distribuidores están interesados en buscar un sistema de gestión empresarial sencillo, adecuado y de fácil manejo que permitirá únicamente a todos los concesionarios presentar sus estados de cuenta y desarrollo de una manera estandarizada a su distribuidor directamente. Entonces, el sistema deseado debe ser capaz de generar resultados basándose en lo comunicado por los distribuidores y proporcionar un conjunto de características bajo una adecuada funcionalidad para permitir a todos los usuarios de la red (concesionarios, distribuidores y KMC) analizar el rendimiento y desempeño de la empresa e identificar las áreas que requieren una mejora. En el siguiente documento, podremos ver el desarrollo que ha tenido METROKIA S.A para la creación y aplicación de una herramienta tecnológica (software) enfocada en lo mencionado anteriormente. Ha sido un proceso de varias etapas en donde tanto las variables como los indicadores de desempeño han tenido correcciones con el fin de poder ser leídos y entendidos fácilmente por toda la organización y red de concesionarios afiliados.

Comunicar com símbolos em contexto inclusivo : aplicação de software educativo

O presente estudo de investigação-ação partiu da necessidade de investigar e aprofundar a aprendizagem do mecanismo da leitura e da escrita numa criança com Paralisia Cerebral mediante a aplicação do software educativo “Comunicar com Símbolos”. O trabalho desenvolveu-se inicialmente num Centro Escolar de um Agrupamento de Escolas da zona centro do país, no distrito de Santarém, passando a realizar-se, após avaliação diagnóstica, numa Instituição Particular de Segurança Social - Centro de Deficientes Profundos da mesma região e analisa essencialmente o desenvolvimento da aprendizagem da leitura e da escrita numa criança com Paralisia Cerebral Espástica Bilateral com predomínio nos membros inferiores através da aplicação de dez sessões planificadas com base na utilização do software educativo Comunicar com Símbolos, da Cnotinfor – Imagina. Após a intervenção e a análise dos resultados, concluiu-se que o programa informático supramencionado apresenta vantagens significativas na consolidação da leitura e da escrita da criança com Paralisia Cerbral. Este trabalho de natureza interventiva não pretende, de forma alguma, dar respostas únicas na implementação de estratégias na melhoria do desenvolvimento do mecanismo da leitura e da escrita em crianças com Paralisia Cerebral, mas apenas contribuir para uma reflexão aprofundada sobre a importância da aplicação das tecnologias de apoio na prática pedagógica com crianças com Necessidades Educativas Especiais, no geral.

Real-Time software control of neural stimulation in a closed loop Animat system

A recent area for investigation into the development of adaptable robot control is the use of living neuronal networks to control a mobile robot. The so-called Animat paradigm comprises a neuronal network (the ‘brain’) connected to an external embodiment (in this case a mobile robot), facilitating potentially robust, adaptable robot control and increased understanding of neural processes. Sensory input from the robot is provided to the neuronal network via stimulation on a number of electrodes embedded in a specialist Petri dish (Multi Electrode Array (MEA)); accurate control of this stimulation is vital. We present software tools allowing precise, near real-time control of electrical stimulation on MEAs, with fast switching between electrodes and the application of custom stimulus waveforms. These Linux-based tools are compatible with the widely used MEABench data acquisition system. Benefits include rapid stimulus modulation in response to neuronal activity (closed loop) and batch processing of stimulation protocols.

Development and illustrative outputs of the Community Integrated Assessment System (CIAS), a multi-institutional modular integrated assessment approach for modelling climate change.

This paper describes the development and first results of the “Community Integrated Assessment System” (CIAS), a unique multi-institutional modular and flexible integrated assessment system for modelling climate change. Key to this development is the supporting software infrastructure, SoftIAM. Through it, CIAS is distributed between the community of institutions which has each contributed modules to the CIAS system. At the heart of SoftIAM is the Bespoke Framework Generator (BFG) which enables flexibility in the assembly and composition of individual modules from a pool to form coupled models within CIAS, and flexibility in their deployment onto the available software and hardware resources. Such flexibility greatly enhances modellers’ ability to re-configure the CIAS coupled models to answer different questions, thus tracking evolving policy needs. It also allows rigorous testing of the robustness of IA modelling results to the use of different component modules representing the same processes (for example, the economy). Such processes are often modelled in very different ways, using different paradigms, at the participating institutions. An illustrative application to the study of the relationship between the economy and the earth’s climate system is provided.

HDC poinsettia tracker: flexible graphical tracking software

Growing pot poinsettia and similar crops involves careful crop monitoring and management to ensure that height specifications are met. Graphical tracking represents a target driven approach to decision support with simple interpretation. HDC (Horticultural Development Council) Poinsettia Tracker implements a graphical track based on the Generalised Logistic Curve, similar to that of other tracking packages. Any set of curve parameters can be used to track crop progress. However, graphical tracks must be expected to be site and cultivar specific. By providing a simple Curve fitting function, growers can easily develop their own site and variety specific ideal tracks based on past records with increasing quality as more seasons' data are added.

Teachers as researchers and teachers as software developers: how use-case analysis helps build better educational software

A series of government initiatives has raised both the profile of ICT in the curriculum and the expectation that high quality teaching and learning resources will be accessible across electronic networks. In order for e-learning resources such as websites to have the maximum educational impact, teachers need to be involved in their design and development. Use-case analysis provides a means of defining user requirements and other constraints in such a way that software developers can produce e-learning resources which reflect teachers' professional knowledge and support their classroom practice. It has some features in common with the participatory action research used to develop other aspects of classroom practice. Two case-studies are presented: one involves the development of an on-line resource centred on transcripts of original historical documents; the other describes how 'Learning how to Learn', a major, distributed research project funded under the ESRC Teaching and Learning Research Programme is using use-case analysis to develop web resources and services.

The development of the spatial extent of oculomotor inhibition

Inhibition is intimately involved in the ability to select a target for a goal-directed movement. The effect of distracters on the deviation of oculomotor trajectories and landing positions provides evidence of such inhibition. individual saccade trajectories and landing positions may deviate initially either towards, or away from, a competing distracter-the direction and extent of this deviation depends upon saccade latency and the target to distracter separation. However, the underlying commonality of the sources of oculomotor inhibition has not been investigated. Here we report the relationship between distracter-related deviation of saccade trajectory, landing position and saccade latency. Observers saccaded to a target which could be accompanied by a distracter shown at various distances from very close (10 angular degrees) to far away (120 angular degrees). A fixation-gap paradigm was used to manipulate latency independently of the influence of competing distracters. When distracters were close to the target, saccade trajectory and landing position deviated toward the distracter position, while at greater separations landing position was always accurate but trajectories deviated away from the distracters. Different spatial patterns of deviations across latency were found. This pattern of results is consistent with the metrics of the saccade reflecting coarse pooling of the ongoing activity at the distracter location: saccade trajectory reflects activity at saccade initiation while landing position reveals activity at saccade end.

Developing collaborative social software

The Internet has an increasing role in facilitating communication between people and groups of people. As access to the Internet and World Wide Web is widely available, collaborative services enabled over the Internet are also burgeoning. In this paper, we present the current issues and our techniques for developing collaborative social software. We discuss online communities in the context of social collaborative systems. We then describe our approach to the development of supporting software for online communities and collaboration.

Decision theory and real estate development: a note on uncertainty

Real estate development appraisal is a quantification of future expectations. The appraisal model relies upon the valuer/developer having an understanding of the future in terms of the future marketability of the completed development and the future cost of development. In some cases the developer has some degree of control over the possible variation in the variables, as with the cost of construction through the choice of specification. However, other variables, such as the sale price of the final product, are totally dependent upon the vagaries of the market at the completion date. To try to address the risk of a different outcome to the one expected (modelled) the developer will often carry out a sensitivity analysis on the development. However, traditional sensitivity analysis has generally only looked at the best and worst scenarios and has focused on the anticipated or expected outcomes. This does not take into account uncertainty and the range of outcomes that can happen. A fuller analysis should include examination of the uncertainties in each of the components of the appraisal and account for the appropriate distributions of the variables. Similarly, as many of the variables in the model are not independent, the variables need to be correlated. This requires a standardised approach and we suggest that the use of a generic forecasting software package, in this case Crystal Ball, allows the analyst to work with an existing development appraisal model set up in Excel (or other spreadsheet) and to work with a predetermined set of probability distributions. Without a full knowledge of risk, developers are unable to determine the anticipated level of return that should be sought to compensate for the risk. This model allows the user a better understanding of the possible outcomes for the development. Ultimately the final decision will be made relative to current expectations and current business constraints, but by assessing the upside and downside risks more appropriately, the decision maker should be better placed to make a more informed and “better”.

Development of a semantic graph-based scene description

Software representations of scenes, i.e. the modelling of objects in space, are used in many application domains. Current modelling and scene description standards focus on visualisation dimensions, and are intrinsically limited by their dependence upon their semantic interpretation and contextual application by humans. In this paper we propose the need for an open, extensible and semantically rich modelling language, which facilitates a machine-readable semantic structure. We critically review existing standards and techniques, and highlight a need for a semantically focussed scene description language. Based on this defined need we propose a preliminary solution, based on hypergraph theory, and reflect on application domains.

Integrating Sustainability into Brownfield Regeneration: Rhetoric or Reality? – An Analysis of the UK Development Industry

In the UK and elsewhere the use of the term ‘sustainable brownfield regeneration’ has resulted from the interweaving of two key policy themes, comprising ‘sustainable development’ and ‘brownfield regeneration’. This paper provides a critical overview of brownfield policy within the context of the emerging sustainable development agenda in the UK, and examines the development industry's role and attitudes towards key aspects of sustainable development and brownfield regeneration. The paper analyses results from a survey of commercial and residential developers carried out in mid‐2004, underpinned by structured interviews with eleven developers in 2004–2005, which form part of a two‐and‐half‐year EPSRC‐funded project. The results suggest that despite the increasing focus on sustainability in government policy, the development industry seems ill at ease with precisely how sustainable development can be implemented in brownfield schemes. These and other findings, relating to sustainability issues (including the impact of climate change on future brownfield development), have important ramifications for brownfield regeneration policy in the UK. In particular, the research highlights the need for better metrics and benchmarks to be developed to measure ‘sustainable brownfield regeneration’. There also needs to be greater awareness and understanding of alternative clean‐up technologies to ‘dig and dump’.

The development of a data-driven application benchmarking approach to performance modelling

Performance modelling is a useful tool in the lifeycle of high performance scientific software, such as weather and climate models, especially as a means of ensuring efficient use of available computing resources. In particular, sufficiently accurate performance prediction could reduce the effort and experimental computer time required when porting and optimising a climate model to a new machine. In this paper, traditional techniques are used to predict the computation time of a simple shallow water model which is illustrative of the computation (and communication) involved in climate models. These models are compared with real execution data gathered on AMD Opteron-based systems, including several phases of the U.K. academic community HPC resource, HECToR. Some success is had in relating source code to achieved performance for the K10 series of Opterons, but the method is found to be inadequate for the next-generation Interlagos processor. The experience leads to the investigation of a data-driven application benchmarking approach to performance modelling. Results for an early version of the approach are presented using the shallow model as an example.

An aspect-oriented reference architecture for Software Engineering Environments

Reusable and evolvable Software Engineering Environments (SEES) are essential to software production and have increasingly become a need. In another perspective, software architectures and reference architectures have played a significant role in determining the success of software systems. In this paper we present a reference architecture for SEEs, named RefASSET, which is based on concepts coming from the aspect-oriented approach. This architecture is specialized to the software testing domain and the development of tools for that domain is discussed. This and other case studies have pointed out that the use of aspects in RefASSET provides a better Separation of Concerns, resulting in reusable and evolvable SEEs. (C) 2011 Elsevier Inc.
