According to the gas properties, operating parameters, and boundary conditions, DBD can exhibit pronounced filamentary characteristics, self-organized regular-discharge patterns, or completely diffuse appearance [8-10].
The bonding strength is a very important factor relating to bond quality and reliability.
It directly affects the other bonding parameters such as voltage and surface roughness of bonding pairs.

Pure water base fluid and various nanoparticles selected in this study as the working fluid, and the thermophysical properties assumed to be constant.
The physical and thermal properties of base fluid and nanoparticles at the base temperature have been summarized in Table 2.
The change of type of nanoparticle completely modifies the thermophysical properties of the nanofluid thus it directly affects the heat transfer through the annulus.
In general, the Nusselt number increase with volume fraction increase, so it increases when chose a better nanoparticle type corresponding to thermophysical properties.

The properties of clusters depend on their size.
High-speed computing enables a dynamic computer simulation of the properties of real crystals of the GaAs.
It gives the results without making any correction factors, does not require the use of logarithmic scales, and other non-uniform, allows you to quickly calculate the crystalline potential for all elements of the given crystal structure.
This inter-ion lattice in addition to the core determines the physical properties of the crystal.
Discussion Computer simulation of the properties of the crystal lattice gives to use up to 1010 ÷ 1012 atoms.

There are numerous levers and constraints affecting the sustainability of electric motors.
As can be seen, there are numerous sustainability aspects affecting electric motors.
The mechanical commutation requires brush contacts, which makes DC motors maintenance-intensive and affects resource efficiency negatively.
This is why a convection oven only reaches an efficiency factor of approximately 40 % [53].
By measuring, clustering and interim stocking of each individual magnet, the variations of the magnetic properties can be compensated by a proposed selective magnet assembly.

Structural and corresponding dynamic properties of the support structures have considerable effect on the response of the disconnect switches.
In that regard, HS, which allows representation of the support structures with well-defined material and geometrical properties as analytical substructures, comes forward as a cost-effective and efficient testing method alternative to the conventional shaking table testing of these switches.
Proper implementation of the HS algorithm and the measurements used in the algorithm are verified by comparing the RTHS runs conducted for the same set of analytical substructure properties with different scales of the input excitation.
Identical stiffness and mass properties of the insulators tested with the RTHS and the shaking table and resemblance of the boundary conditions at the base of the insulators are confirmed from the similar natural frequencies identified for the insulators from both tests.
Considering that the local response measured by a strain gage is affected by factors such as gage location and orientation, local impurities at the location where the gage is installed, etc., it is judged that the two pairs of strain gage histories in Fig. 26, with close match of peaks, are reasonably comparable.

DESIGN Wing structure was designed to sustain the load having a load factor of 3.8.
The reason why square spars are chosen is that they have good properties in resisting the torsional load as well as bending load.
Since there are ailerons on the wings, the position of the rear spar cannot be very toward otherwise it could deteriorate control surfaces’ bending properties.

During the refinement procedure, the mechanical fields are simply induced from the current mesh to the new mesh.
During the coarsening procedure, the mechanical fields associated to four associated elements are averaged and the result is associated to the new element.
Properties of the used material (steel E24), are summarized in Table 2.
In order to control deformation, it is necessary to change the stress state inside the blank that is affected by many factors such as the blank size and the blank holder force.
