چکیده

Background The three dimensional model of HIV/AIDS is the basis of active research since it includes most aspects regarding the interaction of HIV with patient’s immune system. This model is parameterized by six parameters namely the death rate of CD4 cells, rate of infection of CD4 cells by virus, death rate of CD8 cells, rate of increase of CD8 cells in response to increased viral load, rate of increase of viral load, and rate of decrease of viral load respectively. The objective of this work is to efficiently estimate the HIV parameters using available measurements of viral load.

INVERSE FREQUENCY RESPONSE ANALYSIS FOR PIPELINES LEAK DETECTION USING THE PARTICLE SWARM OPTIMIZATION

Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...

Synchronization of a Heart Delay Model with Using CPSO Algorithm in Presence of Unknown Parameters

Heart chaotic system and the ability of particle swarm optimization (PSO) method motivated us to benefit the method of chaotic particle swarm optimization (CPSO) to synchronize the heart three-oscillator model. It can be a suitable algorithm for strengthening the controller in presence of unknown parameters. In this paper we apply adaptive control (AC) on heart delay model, also examine the sys...

Basic and clinical immunology – 3013. Resource limited estimation of HIV-1 viral load from CD4 cell count using coupled bacterial foraging/jumping frogs algorithm

Background Viral load (VL) testing is highly important for detection of antiretroviral treatment (ART) failure in AIDS patients. However, due to the cost and availability of viral load testing instruments, VL testing is not being performed in many developing and underdeveloped countries. Such countries depend on CD4 tests for staging the HIV infection and for initiating ART, since CD4 testing i...

A Heuristic Approach for Optimization of Gearbox Dimension

A powerful optimization method is proposed in this study for the minimal dimensional design problem of gearbox. It is a general model that is suitable to use for any series of gear drives system and can extract both dimensional and layout of components-limited optimization design together. The objective function in this study has many local extremes so for avoiding this situation, various const...
