This paper deals with an analytical approach to predict the nonlinear buckling behavior of functionally graded graphene-reinforced composite laminated cylindrical shells under axial compressive load surrounded by Pasternak’s elastic foundation in a thermal environment. Piece-wise functionally graded graphene-reinforced, composite layers are sorted with different types of graphene distribution. ...

Many asteroids and comets orbit the inner solar system; among them Near Earth Objects (NEOs) are those celestial bodies for which the orbit lies close, and sometimes crosses, the Earth’s orbit. Over the last decades the impact hazard they pose to the Earth has generated heated discussions on the required measures to react to such a scenario. The aim of the research presented in this dissertatio...

A deflection routing algorithm that can be applied to a novel self-routing address scheme for networks with arbitrary topology is proposed. The proposed deflection routing algorithm can be implemented all-optically using bitwise optical logic gates. Besides the primary output link selection, alternate output link choices by a packet at each node in case of deflection are also encoded in the add...

introduction the aim of this study was to compare the characteristics of deflection load of three kinds of nickel titanium closed coil springs. methods and materials this research was an experimental study. research sample contains three kinds of niti closed coiled springs (heavy, medium, light) from gac, 3m, and rmo factories. 10 springs with 9 mm length for each group (totally 90 springs) wer...

Transparent materials are utilized in different products and have to meet high quality requirements, i.a., they have to be free from scattering defects. Such material defects are mainly manifested in changes of the direction of light transmitted through the object. Laser deflection scanners can acquire so-called four-dimensional light deflection maps conveying both, the spatial and angular info...

Contention resolution schemes are the key determinant of the network performance in optical packet switched networks. This paper presents a contention resolution scheme in wavelength and space dimension. By integrating deflection routing with wavelength conversion, this paper investigates their effects on packet-loss performance through simulation studies. In particular, we propose a load-sensi...

   18F-FDG is the most commonly used radioisotope in PET scanning and is administered intravenously. When patients cannot cannulated, there are limited options available for functional tumour assessment. A fifty year old male presented for investigation of a suspected lung carcinoma identified during investigation of pneumonia. The patient had a severe needle phobia, intellectual dis...

The purpose of the present study was to evaluate the relationship between the amount of cuspal deflection and linear polymerization shrinkage in resin composite and polyacid modified resin composite. For cuspal defelction and shrinkage measurement, Dyract AP, Compoglass F, Z100, Surefil, Pyramid, Synergy Compact, Heliomolar and Heliomolar HB were used. For measuring polymerization shrinkage, a ...

Anaerobic threshold which describes the onset of systematic increase in blood lactate concentration is a widely used concept in clinical and sports medicine. A deflection point between heart rate-work rate has been introduced to determine the anaerobic threshold non-invasively. However, some researchers have consistently reported a heart rate deflection at higher work rates, while others have n...
