This paper presents an approach using the method of separation of variables applied to 2D Helmholtz equations in the Cartesian coordinate. The solution is then computed by a series solutions resulted from solving a sequence of 1D problems, in which the 1D solutions are computed using pollution free difference schemes. Moreover, non-polluted numerical integration formulae are constructed to hand...
The biological effects of electromagnetic fields have seriously concerned the scientific community and the public as well in the past decades as more and more evidence has accumulated about the hazardous consequences of so-called "electromagnetic pollution." This theoretical model is based on the simple hypothesis that an oscillating external electric field will exert an oscillating force to ea...
Today, there is an increasing interest in the use of metal nanoparticles in health sciences. Amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. On the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...
In this paper we present a modeling and simulation, the methodology for calculating the electromagnetic field radiated by the high voltage (HV) lines and for selection of analytical models that interpret the electric and magnetic fields as a function of the distance to the target object. The results were compared with measurements carried out on site where the HV lines are present through a nei...
Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...
The present Chapter describes a methodical approach to the design of a monitoring process for environmental applications. The case study and experimental results concern the remote control of exposure levels to electromagnetic pollution. The main contribution focuses on the design of a configurable network of wireless and smart web-sensors and the development of a two-levels data fusion procedu...
In parallel with the development of technology, increase in number devices emitting electromagnetic wave also increases rate pollution surrounding our environment. Determination level is great importance for human health. present study, it was aimed to measure electric field values Bitlis Eren University main campus and vocational school Turkey. Spectran HF60105 used perform measurements at dif...
