Adverse Impacts

These days mobile phones have become associated with elementary a part of our life, this is often one in every of the foremost necessary mediums for communication. Consequently, several portable towers are planted to hide additional areas, particularly in huddled cities and concrete areas. Now, the bottom stations made on these locations have transceivers that employ mistreatment frequency (RF) waves to determine communication among users within the mobile network. Because of the variety of base stations needed it will increase with bigger portable use with market competition, and with new technological capabilities. The microwave frequencies utilized in mobile communication cause thermal and non-thermal effects and leave a negative impact on the biological system. The quantity of RF-EMW radiation energy absorbed by human tissue depends on the frequency, intensity, polarization, and period of exposure. The EMR is recognized because of the major reason behind cancer. This review paper presents the potential biological and medicine health effects of high-intensity portable tower radiation.

Ionizing Radiations

Nowadays nearly more than half of human beings on the planet are directly or indirectly exposed to an “evolutionary” novel physical agent: the electromagnetic fields (EMFs) emitted by cellular phones, base stations, as well as other types of wireless communication technologies. More than 10 years ago several studies reported that cognitive functions of human beings may have been altered while exposed to radiofrequency (RF) EMFs. Yet, the genuine effect of these non-ionizing radiations on human behaviour was not replicated by several other recent and more methodologically robust studies. Latest reviews and metanalyses confirmed the paucity of evidence in favour of psychomotor and cognitive effects of acute RF EMF exposure on human volunteers in well controlled laboratory settings. Thus, despite persisting concerns on potential biologic effects of acute RF EMFs irradiation, there is substantial lack of evidence that RF radiation can affect cognitive functions in humans.

The People

On a global scale, the telecommunication industry is experiencing tremendous growth in mobile phones. Mobile phones communicate with base stations that are erected by the telecommunication industry. The base station produces radio frequency and exposes the people near the base stations to radiation. The effect of electromagnetic radiation from four base stations located at the residential area was studied by measuring their electric field strength and calculating their magnetic field strength and power density at different distances covering a frequency range of 900MHz to 2100MHz. The obtained values showed that the four cellular base stations are operating above the standard values of the International Commission on Non-Ionizing Radiation Protection Electromagnetic Field Radiation. The specific absorption rate was measured to determine the amount of radio frequency electromagnetic radiation absorbed by the human body. The result which is in the range of 3.22-3.70 W/kg is higher than the acceptable 2 W/kg for localized specific absorption rate.

Current global markets are volatile, where companies are striving to deliver greater quality, more customization, faster response, more innovative designs and lower prices. New models need to be introduced in the market more frequently, which has given momentum for designing family of products. Development of family of Products using a platform approach requires making decisions regarding platform selection and trade-off studies, which require analysis and evaluation of performance for the entire family instead of an individual products. One of the first steps in performing these activities require development of solid models for the entire family quickly and automatically as platform and family member configurations and size are changed. This paper presents an approach to automatically generate CAD models for a family of products. In the approach, a product family template that integrates configuration and parametric design information is presented. The template is implemented in the developed Product Family CAD (PF-CAD) module for Pro/E. A coffeemaker product family is used as a case study to automatically generate solid models of product family members from customer input.

Fea Analysis

Designing family of products require analysis and evaluation of performance for the entire product family. In the past, products were mainly mass-produced hence the use of CAD/CAE was restricted to developing and analyzing individual products. Since the products offered using a platform approach include a variety of products built upon a common platform, CAD/CAE tools need to be explored further to assist in customization of products according to the customer needs. In this paper we investigate the development of a Product Family FEA (PFFEA) module that can support FEA analysis of user customized product families members. Customer specifications for family members are gathered using the internet, users are allowed to scale and change configurations of products. These specifications are then used to automatically generate 3D solid models of the product and then perform FEA to determine feasibility of the customer specified product. In this paper, development of the PFFEA module is illustrated using a family of lawn trimmer and edger. The PFFEA module uses Pro/E to generate the solid model and ANSYS as the base FEA software.
