...
Gómez-Botero, M. A. (Maryory Astrid) | 2014-05-12

Laser materials processing has great application to industrial scale, to print graphic patterns on ceramics surfaces. The fast implementation of this process is due to the fact that, with respect to the conventional baking process, has advantages, such as: heat is concentrated only in the radiated zone that involves a smaller energy consumption without affecting significantly the rest of the piece, graphic patterns with of highly spatial resolution are obtained, it permits to introduce changes during the process without requiring long stops, and low or almost none generation of residues. In this study the results obtained from Nd:YAG (λ=1064 nm) laser glazing on the enameled surfaces of glazed tiles, which were previously covered with black of cobalt pigment, are presented. With the laser operating in continuous wave (CW), a series of lines were marked, whose width and depth showed a direct dependence with the variation in the power and scan speed of the laser beam on the surface of the glazed tile. Finally, these glazed lines were characterized by optical microscopy, energy dispersion spectroscopy (EDS), and X-ray diffraction (XRD).

MDA y el papel de los modelos en el proceso de desarrollo de software
...
Quintero, J. B. (Juan Bernardo) | 2014-05-09

The role of models is critical in software development to enable the reuse of different software elements and to aid the work of several roles involved in the process. Model Driven Architecture (MDA) suggests a development process based on models realization and transformation. The principles in which MDA is based are abstraction, automation, and standardization. The central process of MDA is the transformation of models from the problem space (CIM) to platform specific models (PSM), passing across models describing a platform independent solution (PIM). In order to explain the model role in the software process development, this paper explores the main concept presented in the MDA proposal.

...
Pérez-Rave, Jorge Iván | 2013-11-18

A heuristic model is proposed to determine the capacity of the manufacturing companies to analyze their processes from the failure. For its development, thirty companies, located in the Aburrá Valley (Antioquia, Colombia), were analyzed through descriptive transverse study. The model is a function of 16 items about collecting, documenting, and updating of information relating to possible failure events. For validation are selected two methods: first, the Cronbach’s alpha coefficient (0.85) approach; second, the comparison between answer categories (low, medium, and high) and description of five industrial features: age, utilization of SGC ISO 9000, employee turnover, failure records, and competitive interests. This study shows that 57 % of enterprises studied were classified as high capacity, 26 % as medium capacity and 17 % as low capacity. SMEs show disadvantages. With this model can be identified mature companies in the field and others that deserve support to analyze and respond with data and facts to the elimination of the root causes of their problems.

Torres, P. (Patricia) | 2013-11-27

One of the main quality problems of biosolids from domestic wastewater treatment plants –WWTP– is the high concentration of pathogens, often classified as a class B, with restriction for use in agriculture. This study evaluated the alkali stabilization of biosolids from Cañaveralejo wastewater treatment plant (PTAR-C), located in Cali, Colombia, in order to improve their microbiological quality using two types of lime (quick and hydrated) with doses between 8 to 25 % and two types of ash with 8 to 40 % as doses, in experimental units 0,2 m2 with 13 days of contact time. The results showed that both type of lime reached the total reduction of evaluated monitoring variables (faecal coliforms, Salmonella sp, helmints eggs) while the alkali power of ashes were lower. The obtained biosolids treated with lime have a high potential use in agriculture purposes for the good microbiological quality, and for the organic matter and nutrient content (N, P) that can generate benefit to the soil, but it is recommendable to evaluate at pilot scale the lime doses and application of biosolid in different soils types and crops in order to precise the benefits or prevent measurements before application of material in soil.

Coca-Ortegón, G. A. (Germán Augusto) | 2013-10-29

This paper presents a methodology that aims to minimize simultaneously, in a “Jo b Shop” production system the following variables: process time (makespan time), cost of direct labor and also the fraction defective generated by operator fatigue. For this purpose, are taken and fused elements of genetic algorithms Vega and Moga, through the following steps: generating the initial population, form the new population, obtaining the appropriate analysis of variance and finally compared with a hybrid method of weighted sums and genetic algorithms. According to the above, when evaluating the solution faster processing time corresponding to the method based on algorithms Vega and Moga, respect to the solution faster processing time calculated from the method based on weighted sums and genetic algorithms, states that the first one exceeds the second performance as: for process time variable (in hours) at 27.86%, for variable in process time (in weeks) at 1.25%, in terms of the variable cost of direct labor in 6.73% and, as to the variable defective fraction in 25.85%.

Barros-Martínez, J. F. (Juan Fernando) | 2014-05-08

A methodology for the evaluation of the condition of urban streams is proposed. The methodology integrates field data, historical information and technical analysis; it could be applied to the hydraulic component of the physical subsystem to comply with the ordering plans for watersheds. Pointers to measure the condition of the streams and the watershed are defined, the connection between portions of the streams with different hydraulic capacity conditions is analyzed and a multicriteria analysis is developed. This analysis compiles all the information gathered and identifies the most critical points of the hydraulic network based on three basic criteria: field evaluation, flooding records, and hydraulic capacity.

Zapata-Jaramillo, C. M. (Carlos Mario) | 2014-05-09

Software reverse engineering seems to be the process for helping software quality assurance and documentation in applications with low-quality analysis and design models. It also helps for decreasing maintenance cost and time. Currently, some CASE tools and research proposals assist analysts to develop reverse engineering process with UML diagrams as a result (especially class and sequence diagram). Some of them have reached experimental phases. Some others are focused more on class diagram and less on sequence diagram. A third group of CASE tools and proposals obtains sequence diagram, but the resulting diagram lacks some of the elements of the UML 2.0 specification. In this paper, we propose a method for automating the conversion of JAVA code into UML 2.0 sequence diagram, by means of the application of transformation rules for converting code elements to the diagram elements. We also present an example of the method application through a prototype named UNC-Inversor.

...
Tabares-Betancur, M. S. (Marta Silvia) | 2014-05-08

Unified Process is the development process adopted by many software development companies. Quality attributes, such as requirement traceability, must be standardized for this process, so that the system can achieve the quality demanded by customers. Commonly, traceability models are proposed independently of either the development process or the methodology that are followed, and its definition and maintenance depends on the quality criteria used by the developers. A traceability method for the Unified Development Process is presented in this paper. This approach proposes a workflow to control and support traceability throughout the iterations of the process. This workflow establishes a set of actions capable of generating traceability models that facilitate opportune agreement with the customers.

Torres, P. (Patricia) | 2013-11-20

In Colombia, the agroindustry of cassava-starch extraction is an important sector of the country's economy; production is focused in Cauca Department; this process uses fresh cassava-roots, water, and electricity as main resources, generating solid and liquid wastes whose inadequate use or disposal brings environmental and economic impacts. In this study were made measures for process optimization supported by tools such as mass balance and study methods, time and motion, considering the technological and socio-economic context of the sector. The results showed process-efficiency between 51 and 59 %; it was identified that the straining stage has the highest water consumption and solid waste generation (fiber cassava pulp); the starch slurry’s sedimentation stage generates the most amount of liquid wastes with high-pollution load. It evidenced the need to standardize and optimize the washing-peeling and strain stages because they require the largest process times; to increase the grating-rasping machine capacity (this critical stage influences the process efficiency and the final starch quality) besides recording the process information as control strategy.

Zapata, Carlos Mario | 2013-11-25

Automated code generation is fostered by several software development methods. This generation is often supplied by well-known CASE (Computer-Aided Software Engineering) tools. However, automation is still so far and some CASE tools are complemented by non-standard modeling projects. In this paper, we conceptualize projects related to automated code generation, starting from discourse representations in either controlled or natural language, or in conceptual schemas. In this way, we present a graphical summary of crucial concepts related to this issue, by means of a state-of-the-art review. We conclude that automated code generation usually begins from solution-based representations of the problem instead of domain-based representations. Also, we summarize that these starting points are misunderstood by the client and this situation leads to poor validation in early stages of software development lifecycle.

A simple method to determine the magnetic field generated by transmission lines is presented in this paper. The magnetic field calculation takes into account the mitigating effects of passive loops, including their optimal position in the line by applying genetic algorithms. Calculations results are validated by case reports published in the IEEE Transactions, software package for electromagnetic field analysis, and experimental data obtained from an implementation made in the power lines at a stadium lighting tower. After the analysis, the method’s validity and feasibility of its application to transmission lines power systems are demonstrated.

Con el poder creciente y la miniaturización de los dispositivos móviles, nuevas áreas de estudio han encontrado en esta tecnología una nueva forma de visualización e interacción. La realidad aumentada, como una prometedora metáfora de interacción humano-máquina, no es la excepción. Aunque debido ante todo a limitaciones de procesamiento y hardware, los móviles no ofrecen una solución viable para algunas aplicaciones de realidad aumentada de propósito general, otras aplicaciones los han utilizado con éxito para visualizar información gráfica virtual en entornos reales. En este artículo presentamos experiencias adquiridas con el uso de realidad aumentada en dispositivos móviles como metáfora de la visualización. Específicamente, nos concentramos en la necesidad de preservar el patrimonio cultural para proponer la realidad aumentada como una interfaz para visualizar dicho patrimonio. Este artículo presenta dos aportes principales: el primero, la forma de visualización de patrimonio cultural colombiano y el segundo, una mejora de la experiencia del usuario al presentar piezas culturales colombianas detalladas. Se creó un museo aumentado como caso de estudio y se evalúa la viabilidad del uso de dispositivos de mano para la visualización.

...
Cárdenas-Poblador, J. (Jaleydi) | 2013-11-27

The rheological properties of asphalt are directly related to its chemical composition, which varies with the origin of crude oil. The rheological behavior of the binder has a significant influence on the properties of the asphalt- -aggregate mixture (truck-wheel test, fatigue, and thermal susceptibility,). To describe the rheological behavior of asphalt from the Barrancabermeja Industrial Complex (IBC) and the modified asphalt with recycled material (polystyrene and tire rubber) with and without control of particle size, viscosity measurements were conducted at different temperatures (intervals of 2 º C) with a Brookfield rotational viscometer, and from these data suggested several mathematical expressions that describe the behavior of viscosity in terms of temperature, were evaluated in terms of the coefficient of determination, and determined the mixing and compaction temperatures. The results indicate that the best fit in the three cases corresponds to the Arrhenius model truncation, correlations between 0.9945 and 0.9968.

González, Liliana | 2013-11-15

This paper presents a proposal for the conceptual modeling of user in ubiquitous environments through agents and ontologies. The integration of these two concepts allows capturing, process, and maintaining user information of pervasive systems. The approach consists of conceptual architecture, types of agents that compose the system, basic structure of each agent and communication strategy. It also presents ontology to model users. Later presents two scenarios of interaction of agents: connection request to the system and sending a query. This proposal solves problems such as lack of standardization in the user modeling of ubiquitous systems and the lack of intelligent component for processing the user’s information to offer personal configurations that depend of the users' profile and preferences.

Giraldo, L. P. (Lía Patricia) | 2014-05-07

Source Matelas, located in the West State, Republic of Haiti, is a town with scarce economical resources and low quality of life, mainly because of the absence almost total of water. In this work we give a first approximation to a water reservoir pre-feasibility study, related to water supply quantification of the region, by means of hydrological methods to estimate unknown information. Long term components of the hydrological balance are calculated and daily mean yield that serves the model of reservoir simulation is estimated. The mean runoff calculated for the Source Matelas River is 0.026 m3/s. Based on reservoir modeling, volume needed to supply different percentages of the mean runoff is calculated. Therefore, it can be seen that population water demand will be supplied totally if a reservoir of 212000 m3 volume is constructed.

Barrera-Zapata, R. (Rolando) | 2013-11-07

Se emplearon herramientas de software de simulación como Aspen Plus y MATLAB para el modelado, simulación y optimización de un proceso de destilación para recuperar epóxido de limoneno a partir de una mezcla líquida que contiene limoneno + acetonitrilo + agua + epóxido de limoneno. Esta mezcla se obtiene de la epoxidación de limoneno sobre PW-Amberlita utilizando peróxido de hidrógeno acuoso como oxidante y acetonitrilo como disolvente. Los análisis de curvas de composición residual indicaron que las columnas de destilación por lotes de configuración inversa son adecuadas para separar el epóxido de limoneno. Los parámetros del modelo, como el número de etapas (8) y la relación de reflujo (3,1) se determinaron mediante simulaciones de estado estacionario con modelos cortos y rigurosos de Aspen Plus. La simulación del equipo por lotes en Aspen Plus mostró que es posible recuperar hasta el 95 % del epóxido de limoneno con una fracción molar de 0,97 después de 7,5 h. Con fines comparativos, la destilación por lotes también se simuló con un modelo semirriguroso construido en MATLAB, con el cual se lograron resultados similares.
