In order to simulate neutron shields, MCNP5 calculation code was used and three types of homogeneous and separated shield multilayer arrangement, irradiated with 241Am-Be neutron sources were investigated. In these shields, the polyethylene (C2H4) and polystyrene (C8H8) were used as moderator material, and the boron carbide (B4C), as a thermal neutron absorber material and stainless steel as a ...

In this paper we propose to attach radio frequency (RF) shields on mobile phone to reduce Specific Absorption Rate (SAR) in the spherical head model. Shields made of ferrimagnetic materials are used to suppress surface currents on the mobile phone. Many kinds of simulation are performed to investigate the effect of various parameters like location, size, shape and thickness of the shield on the...

In this paper we present structuring concepts for networked systems management. The concepts mainly deal with organizing and structuring management systems by introducing building blocks (called domains) and managed resources abstract representations (called shields). Domains are used as a means for grouping resources according to different criteria and shields are used, within domains, to reve...
