About the Light Dimensions

Florian Ion T. Petrescu and John Kaiser Calautit
Light is one of the most fascinating something of all the time. This paper aims to develop a tool with which one can determine with great accuracy the dimensions of light. Basically was entered a new relationship through which one may determine the size of a photon depending on the wavelength of light. Instead wavelength of light can be used as variable the speed of light and its frequency. One could determine this new expressions using and the known equations: the total energy of a moving parti...

Key-Hole Notches in Isostatic Graphite: A Review of Some Recent Data

Filippo Berto, A. Gagani, Relly Victoria V. Petrescu and Florian Ion T. Petrescu
Fracture of the breakable isostatic graphite is concerned using the experimental and theoretically, the plates containing nicks holes key subject to varying degrees of mixed task. The main purpose of this work is a double one. In the first place, in order to offer a new set of experimental results on fracture of samples of graphite scored, with different values of the load mixed and radii notch and which may be helpful for researchers, as it enlarges the very limited data available; and secondly...

Finite Element Analysis, 3d Model, Lap Joint, Notc h Stress Intensity Factors

Filippo Berto, Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella and Florian Ion T. Petrescu
Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. The main stages of fatigue failure of an assembly are the initiation of cracks (if defects are not already present in the materi...

Three-Dimensional in Bonded Joints: A Short Review

Filippo Berto, Relly Victoria V. Petrescu and Florian Ion T. Petrescu
Distributions of stress 3D in the vicinity of the overlapping corners of joints with a single lap were investigated with accuracy at present the man. A (Fe), model accurately Finite Element 3D has been carried out in order to investigate the intensity of the stress of adjustments in the plan and outside of stress by the width of the plate. The influences of the thickness of the adhesive and the Poisson distribution have been taken into account. Numerical results showed the presence of modes enga...

A Review of Recent Results on 3D Effects

Filippo Berto, Relly Victoria V. Petrescu and Florian Ion T. Petrescu
Three dimensions or three-dimensional or 3D are expressions that characterize the space around us, as perceived by our vision, in terms of width, height and depth. The term "3D" is also (and improperly) used to refer to the representation in synthetic (digital) images, the relief of stereoscopic images or other images in relief and sometimes even the simple stereophonic effect, which Can only render 2D (it is therefore only the calculation of the projected projections, the shadows, the rendering...

Hybrid Ceramo-Polymeric Nanocomposite for Biomimetic Scaffolds Design and Preparation

Raffaella Aversa, Relly Victoria V. Petrescu, Roberto Sorrentino, Florian Ion T. Petrescu and Antonio Apicella
Biomimetics, biomechanics and tissue engineering are three multidisciplinary fields that have been contemplated in this research to attain the objective of improving prosthetic implants reliability. Since testing and mathematical methods are closely interlaced, a promising approach seemed to be the combination of in vitro and in vivo experiments with computer simulations (in silico). An innovative biomimetics and biomechanics approach and new synthetic structure providing a microenvironment, whi...

Future Medicine Services Robotics

Relly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella and Florian Ion T. Petrescu
It is an entry technique in use recently, albeit in selected centers and represents a further step in the field of minimally invasive surgery. Basically it has the same indications but, at present, is reserved for selected patients. Compared to traditional video-assisted surgery presents some important differences. The surgeon is physically distant from the operative field and sits at a console, equipped with a monitor, from which, through a complex system, controls the movement of the robotic a...

The Quality of Transport and Environmental Protection, Part I

Relly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis, Apicella Antonio and Florian Ion Tiberiu Petrescu
The today main challenge to protect the environment through the development of new and more efficient transportation systems is presented. The absolutely necessary goods distribution and human transfers are polluting and damaging the environment and new solution should be envisaged; the conflicting strategies to adopt new types of environment friendly transportation while maintaining operative the more economically convenient, but largely polluting, already existing machines are discussed and co...

Some Basic Reactions in Nuclear Fusion

Relly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis, Apicella Antonio and Florian Ion Tiberiu Petrescu
Over time it has advanced the idea that the achievement of a hot nuclear reaction can require tens or hundreds of millions of degrees. Precise calculations clearly indicate a much higher temperature. At least 10 million degrees are necessary for 1 keV in thermonuclear reaction. At 400 keV it needs a temperature of 4000 million degrees to occur the hot fusion reaction. Hot fusion needs a temperature of about 4000 million degrees, or 4 billion degrees if we believe in the calculations the radius o...
