...
López, F. (Fredy) | 2013-11-22

Major Colombian cities face the beginning of the 21st century with an additional concern in their possibilities for development, sustainability, and inhabitability: urban mobility. This term, easily associated with the way vehicles and individuals flow through the different urban transport infrastructure options, has more background and involves the study of how these cities have materialized in time. It implies, therefore, a broader reading that must be established from a different frame of knowledge. Universidad de San Buenaventura and Universidad de Medellín, in the city of Medellín, Colombia, have coincided in studying the mobility problem and their effect on the territorial occupation of that city. The present paper offers the results of the above mentioned research for which assumes a conceptual position about the term “mobility”, it relates the mobility to the occupation of Medellin by means of key variables and map algebra and establishes as conclusion some directions to be considered in the planning of the space. We found that several aspects of city life, like occupation density, property purchase decisions, transportation options, and territorial planning have different consequences on mobility and allow offering solutions.

...
Mejía-Garcés, F. J. (Francisco Jaime) | 2014-05-09

One objective of an introductory course of open-channel flow is the analysis of gradually varied flow profiles. This paper shows a teaching-learning strategy that might improve the university practices for teaching hydraulics. It is well known the depth-specific energy curve (y-E) for describing and interpreting open-channel flow hydraulics. It is proposed to complement that curve with the depth-energy slope curve (y-sf). By using a graphic comparison, it aims to illustrate the concepts of the subcritical (y>ycritical, v<vcritical), critical and supercritical flow concepts and, on the other hand, the subnormal (y>ynormal, v<vnormal), normal y supernormal flow concepts. This way, it is proposed to explain the behavior of the twelve possible gradually varied flow profiles.

...
González, M. (Maribel) | 2014-05-12

Experimental results from a series of biological unitary processes for the simultaneous removal of organic matter (OM), nitrogen (N) and phosphorus (P) are shown in this study. A synthetic substrate similar to a domestic wastewater of average concentration was used. The experimental development was made using an A2O system (anoxic-aerobic-anaerobic) performed in two phases. The preliminary stage lasted 60 days and included, besides the acclimatization of the biological sludge, the examination of polyurethane foam as a support medium in the aerobic phase. In the secondary stage, the stability was rapidly reached; this phase lasted 280 more days; a significant increase of the removal efficiencies was observed to be close to 92.5 % in organic matter, 87.7 % in nitrogen, and 83.5 % in phosphorus. Parameters such as dissolved oxygen (DO) and oxide reduction potential (ORP) were permanently monitored and maintained in values according to the requirements of the processes in each reactor. On the other hand, pH was measured to be higher than 7.2 units, ensuring the viability of the nitrification-denitrification processes. A hydraulic study using tracers was developed in order to find out the effect of the support medium on the hydraulic regimen of the aerobic reactor.

Aguirre, A. F. (Andrés Felipe) | 2013-11-25

Micro, small and medium-sized software development enterprises are one of the most representative sectors of the global economy. For this reason, obtaining concrete results in the actual context through the methods and models proposed to support software quality is an important contribution to the field of the software industry. In this sense, this paper presents the application of the models proposed by Competisoft (an Iberoamerican project focused on increasing the competitiveness of small enterprises through the process improvement strategy), in order to drive the improvement of some software processes into five Colombian small and medium-sized software development companies. Additionally, this paper also shows the behavior of the application of Competisoft from two approaches: (i) determine, for a company, how productive is adoption of this improvement strategy, in terms of effort and progress, and (ii) refine, validate, and improve models of Competisoft based on the results in reports of experience.

Zapata, Carlos Mario | 2013-11-18

Organizational world will always have goals to reach and obstacles to fight, in order to reach those goals. Identifying and representing goals and problems are previous stages in solving problems and establishing goals. These tasks are commonly made in natural language, and no formal methods are used on them. For this reason, in this paper we propose first-order-predicate-logic structures for expressing goals and problems, so we can easily analyze them and establish semantic relationships and consistency among them, making a direct translation from natural language to a phrasal formal representation. This representation leads us to assess true-or-false value of statements.

Resistencia al desgaste erosivo-corrosivo de aceros austeníticos fermanal
...
Aperador, W. (William) | 2013-11-05

We obtained austenitic alloys of the Fe-Mn-Al, Fe in the range (4.9~11.0 wt% Al) - (17.49~34.3 wt% Mn) -(0, 43 ~ 1.25 wt% C), which were melted in an induction furnace from high purity materials. The alloys were evaluated with respect to corrosion, wet erosion and corrosion-erosion at an impact angle of 90°. For the evaluation of corrosion a solution composed of 0.5 M NaCl and silica particles with size between 210 to 300 microns was used in order to analyze the effect of aluminum and manganese content in the resistance to erosion and corrosion-erosion of these alloys. To characterize the corrosion, response technique was used by potentiodynamic polarization curves and using the same technique as Tafel extrapolation, the microstructural characterization by scanning electron microscopy (SEM), and the composition of corrosion products were analyzed using diffraction of X-rays (XRD).

...
Daza-Escorcia, Julio Mario | 2013-11-26

This paper presents an alternative procedure to solve the Capacitated Vehicle Routing Problem (CVRP) with homogeneous fleet. The paper proposes a two-phase metaheuristic algorithm: routes design and fleet scheduling. The first phase is based on heuristics and metaheuristics procedures in order to build an initial solution that is then improved using tabu search to obtain non-dominated solutions in polynomial computational time. For the second phase, corresponding to fleet scheduling, the problem is approached using an analogy with the identical parallel machine scheduling problem. This procedure looks for the minimization of the fixed cost of using installed capacity as the objective function. The proposed procedure was tested using both a random-generated instance and real data, giving competitive results in comparison with other heuristics tested.

Serna, J. P. (Juan Pablo) | 2013-11-08

The respiratory rate of Phragmites australis exposed to synthetic sewage water (SSW) and chlorothalonil (CLT) was evaluated using a respirometer. The study was divided into two phases with the following treatments: phase I with a) tap water, b) tap water + P. australis, c) ARS; phase II with a) SWW+ CLT (0,29 mg L-1), b) SWW + CLT (2,18 mg L-1), c) CLT (0,29 mg L-1), d) CLT (2,18 mg L-1). Each experiment was done by replicate. The influence of relative humidity (RH), solar radiation (SR), air temperature (T), barometric pressure (BP), evaporation and potential evapotranspiration (ETo) on P. australis respiration rate was analyzed. No significant differences were found on the respiratory rate of P. australis (p < 0.05) using tap water and SWW during phase I experiments; the same finding was seen for all phase II experiments. Meteorological variables affected the respiratory rate in all treatments. ETo, T and SR showed significant positive correlation with respiratory rate; RH and BP, a negative correlation.

Arias-Saldarriaga, S. C. (Sandra Cristina) | 2014-05-07

The urban solid wastes generation is a consequence of the human beings’ different activities carried out daily in a municipality. The magnitude of the environmental impact generated is local or regional, depending on how the waste management and disposal are carried out. An experiment was designed in order to study, during six months, variables related to the decomposition and stabilization of the urban solid wastes, some of them dealing with the waste and others with the leachate. From the beginning of the experimentation it was specified that there is an outstanding factor in the observed waste, and it is the exposal to rainfall. Therefore, two experiments with the same conformation conditions, but one subjected to the rain incidence, and other protected by a cover were carried out.

...
Arango, N. (Nolasco) | 2014-05-06

This paper describes and demonstrates the effectiveness of a finite-element procedure to predict the compactation of a green ceramic isostatics pressed plate during sintering process. The approach is based on the conservation of mass principle and requires for its implementation: i) description of the finite element meshes of the green plate when ejected from the press, and ii) the density of the plate after compactation and sintering process. Numerical compactation predictions have been compared with experimental data. The comparisons reveal that the quantitative predictions regarding diameter and height range correlate closely with the measured values showing a difference of 0.52% in diameter and 0.48% in height and a variation on shrinkage of 3.49%. We consider this to be in good agreement, for most practical purposes.

Sistema de alerta temprana por movimientos en masa inducidos por lluvia para el Valle de Aburrá, Colombia
...
Aristizábal, E. (Edier) | 2013-11-25

The complex physical conditions of the Aburrá Valley coupled with high vulnerability levels led to scenarios with a high potential for human and economic losses upon the occurrence of natural phenomena such as mass movements, which represent 35 % of events occurring in the valley and 77 % of dead people. Due to these severe problems, since 2008, an early warning system for rainfall-induced landslides assisted by empirical rainfall thresfolds has been used. Early warning systems provide a rapid means for monitoring and communicating information about threats to a vulnerable community, so they are used primarily to protect lives, noting the possibility of occurrence of an event in advance, providing time to take action that can reduce the risk conditions. This paper describes the definition and model fit as well as presents the results of the validation of thresholds for the period 2004-2008.
