This paper considers the proposal, development and numerical simulation of a system that models the behavior of the treatment of HIV-1 using antiretrovirals. The system defined for three dependent variables of the variable t, denoted by X(t)=(x1 (t), x2 (t), x3 (t)) represent the amount of T Lymphocytes "Helpers" (CD4), number of Cytotoxic T Lymphocytes (CD8) Viral load and infection process of HIV-1 at any time t, respectively. The assembly consists of a Nonlinear Ordinary Differential Equations system whose existential domain represents time system evaluation process of infection and viral clearance in a patient with HIV-1. This set of states of Nonlinear Dynamic System, associated with the initial value condition is called Cauchy problem. There are few studies related to the solution of this system, found some of the study are reduced to two variables and others without obtaining the ...

Currently, textile processing plants need to control the conditions associated with the spinning process, being the air conditioning of working environments an important factor in the quality and productivity of these processes. The benefits obtained from the optimization of this air conditioning help to guide a lower energy consumption, helping to improve the positioning of the products and providing profitability in the operation processes. Due to the advantages obtained in the air conditioning process, this work proposes a system that allows reusing the residual energy generated at the outlet of the ventilation ducts. This residual energy is fed into the plant to reduce the high temperatures observed in the ceiling. Consequently, this approach will generate a decrease in the service demand of the air conditioning system and reduce operating costs. Also, to verify this proposal, a mult...

Thermodynamic simulation models have been developed to observe the behavior of the minor elements Zn, Pb, As, Sb and Bi; as well as the major elements Cu, Fe, Si, 0 and S in the conversion and fusion processes: NORANDA and ISASMELT for the production of copper-rich mattes. The Noranda process shows a steady state model for obtaining a high-grade matte in metallic copper. The lsasmelt process is based on the concept of the two independent reaction sites in the bath (slag-killing interface): rapid oxidation and slow reduction. The heat balance of the process and the distribution thermodynamics of the minor elements are united and expressed in terms of the process variables such as temperature, enriched 02, composition of the charge, degree of matte and content of the magnetite in the Slag and other variables are incorporated into the modeling, which can predict the operating effects of che...

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimati...

The objective of this work has been to analyze and simulate the interactions of atmospheric and hydrological processes using the WRF Model (Weather Research and Forecasting) in Peru for the year 2014. SENAMHI records precipitation data through a meteorological network found distributed in almost all the Peruvian territory. Due to precipitation has a high spatial variability and to the scarcity of rain gauges, the use of TRMM images was used to estimate precipitation and the WRF atmospheric model to analyze the interactions of atmospheric and hydrological processes during different periods and considering the cumulus parameterizations (Kain-Fritsch scheme, KF) and microphysics (Thompson scheme). Thirty- six images of accumulated monthly precipitation over Peru were processed using the simulation of the atmospheric model WRF (two cases) and the TRMM. Twelve meteorological stations distribu...

Mathematical modelling applied to batch milling (at experimental level), is a very important tool to simulate and predict the granulometric yield of a given treated ore; this means, for a given duration of milling operation, to obtain an estimate of the corresponding granulometric analysis, which can then be tested with real data later on, to verify the estimates. The model involves the selection and fracture functions depending on each mesh size in the ore distribution. This will allow the prediction of effective and reliable results, saving costs and more importantly, time, without the need to perform the milling process for each prediction of batch milling.
