Constant struggle in medical science to develop new, more advanced methods of medicine application and reducing the invasiveness of a range of tests and procedures is present. For achieving this ambitious goal, it is necessary to find and develop new methods and technologies and to applicate them. The issue of localizing a range of devices inside the human body is one of them. Solution to this problem...
Precise localization in wireless sensor networks depends on distributed algorithms running on a large number of wireless nodes with reduced energy, processing and memory resources. Prerequisite for the estimation of unique nodes locations is rigid network graph. To satisfy this prerequisite network graph needs to be well connected. On the other hand, execution of distributed algorithm in the graphs...
The effect of Liquid Water Content, i.e. the mass of the water per volume unit of the atmosphere, on the attenuation of a 20 GHz communication link between a ground antenna and communication satellite is tackled in this paper. The wavelength of 20 GHz electromagnetic radiation is comparable to the droplet size, consequently the scattering plays an important role in the attenuation. To better understand...
The development of the electronics during the recent years aims at producing smaller devices with a very high integration, very energy efficient and cost-effective. There is also a tendency that every device should have such communication modules, so that it can connect to the cloud network which is evolving every day. Designing several different antennas into one single PCB, which is small in size,...
