Abstract.
Upscaling the Quality of Service (QoS) and improving the network performance in a dynamic and resource-constrained network like the WBAN is key to sustaining the operability of the network.
Additionally, the implementation incorporates the use of Selenium, a material with a Seebeck coefficient (S) of 900μV/°C.

Therefore, uncertainty is a key criterion.
In addition, in the context of an unstable environment (system engineering, fuel and energy complex, surgery, emergency response), there is a need to make quick decisions, and not only to determine priorities for certain preventive measures [9].
Methods To analyze materials on risks when implemented in management systems, a generalized heuristic method improved by Seuring [22, 23] was used, which gave adequate results in many types of research.
The effectiveness of the risk management process is improved by increasing the expectations consistency with the organization capabilities [38], as well as by narrowing the spectrum of various random events impacts, which ultimately cause significant material damage [40, 41].

Abstract.
Stiffness of the interface material has to be high enough to limit mutual penetration of the volumes and low enough to preserve convergence of the model.
It is linearly dependent on elastic modulus of the material and oppositely dependent on element size [5].

Coating a TiO2 layer on the surface of materials enables the degradation of the organic substances that deposit onto it and accordingly makes these materials self-cleaning under solar light [12,16,17].
In the last years TiO2 coated materials are of increasing interest [12].
This characteristic is widely applied to glasses, mirrors and building materials.
On the materials side, it also seems to be quite probable that new, more versatile materials will become available, greatly expanding the possible range of applications.

From the short review above, key findings emerge on the isolated sample S7 strain 7 is likely a species of B. cereus present in the WTS samples.
This give a highlights that engineering WTS filters to resist bacterial adhesion, such as through the application of antifouling coatings, or surface texturing that target the specific characteristics of the bacterial strains present could prevent the initial attachment of biofilm-forming bacteria.

It is, however, generally accepted that further developments
are limited by fundamental materials and processing aspects [2].
Therefore monolithic solutions are required combining all components into silicon and technology-compatible materials.
Light emission in silicon at wavelengths around 1.5 µm required for optical data communication is obtained either by band gap engineering (using SiGe alloys) or by incorporation of impurities in the depletion layers of pn junctions such as Er or silicides (ß-FeSi2, Ru2Si3) [9, 11, 15].
Results on the adhesion mechanisms on silicon and other materials refer to the strong influence of OH groups on the surface.
This includes the application of different thin layers, such as patternable materials (SU-8, BCB, or other types of photoresist) [43, 44], low-temperature oxide layers (TEOS, SOG, etc.) [45 - 47], and PE-CVD layers (amorphous silicon, oxide, nitride) [48].
