according to the vital role of pharmaceutical industry in health care system, pharmaceutical supply chain security, standard production and distribution of the pharmaceutical products are of great importance for pharmaceutical companies. therefore, applying technology, especially radio frequency identification (rfid), is essential to achieve these goals. moreover, due to the importance of secur...

processing and recovery is a key functional element in municipal solid waste management system (mswms). reuse, recycle and recovery of valuable components of waste stream are given much attention in mswms in both developed and developing countries. the main concern of municipalities is the sound management of recyclable materials. source separation as a best practice for management of trash and...

The paper presents an optimization study based on genetic algorithms (GA’s) for a radio-frequency applicator used in heating dielectric band products. The weakly coupled electro-thermal problem is analyzed using 2D-FEM. The design variables in the optimization process are: the voltage of a supplementary “guard” electrode and six geometric parameters of the applicator. Two objective functions ar...

The grand aim of the Integrated Tokamak Modelling (ITM) task-force is to provide a flexible, modular and reliable plasma simulator in view of planning and analyzing ITER discharges. Since radio-frequency (rf) heating in the ion cyclotron range of frequencies (ICRF) is foreseen as one of the main additional heating systems in ITER, physics modules that simulate ICRF wave propagation and absorpti...

The scale up of an isothermal micro-trickle bed reactor operated under radio frequency (RF) heating has been performed. The effect of the reactor length, tube diameter and number of parallel tubes on the temperature non-uniformity parameter has been studied. The axial and radial temperature profiles were calculated using a 2D convection and conduction heat transfer problem with heat transfer pr...

In the last few years, we have witnessed significant progress in developing high performance shape memory polymer (SMP) nanocomposites, in particular, for shape recovery activated by indirect heating in the presence of electricity, magnetism, light, radio frequency, microwave and radiation, etc. In this paper, we critically review recent findings in Joule heating of SMP nanocomposites incorpora...

accessory pathways (ap) are abnormal myocardial connections between atria and ventricles with electrical conductive properties. we performed radio frequency (rf) catheter ablation in 66 patients with manifest ap at dr.shariati hospital during 5 years. bipolar mapping was used in 48 patients and unipolar mapping in 18 patients of find the best site for rf energy delivery. we calculated total dur...

Susceptors are used in microwavable food packages to facilitate preferential heating. Modeling of susceptor assisted microwave heating in domestic ovens was performed using radio frequency and heat transfer modules of COMSOL Multiphysics 4.2. Two different approaches (domain discretization and transient boundary condition) were studied for taking into the account of discretizing thin susceptor ...

A major problem in the production, storage and marketing of nuts is the infestation of insect pests such as codling moth, naval orangeworm and Indian meal moth. Present and potential quarantine treatments for both domestic and international nut markets include chemical fumigation, ionizing radiation, controlled atmosphere, cold treatment, conventional hot air or water heating and dielectric hea...
