‎in this work‎, ‎first the differential equation characterizing position vector‎ ‎of spacelike curve is obtained in lorentzian plane $mathbb{l}^{2}.$ then the‎ ‎special curves mentioned above are studied in lorentzian plane $mathbb{l}%‎‎^{2}.$ finally some characterizations of these special curves are given in‎ ‎$mathbb{l}^{2}.$‎

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...

Square honeycombs are effective as cores for all-metal sandwich plates in that they combine excellent crushing strength and energy absorption with good stiffness and strength in out-of-plane shear and in-plane stretch. In applications where sandwich plates must absorb significant energy in crushing under intense impulsive loads, dynamic effects play a significant role in the behaviour of the co...

Given the lack of primary data on heat-resistant composites under high-temperature conditions, focus this paper is development an in-plane biaxial apparatus high temperatures and complex loads. Besides loading loads up to 80 kN, can load high-temperatures 2500 °C. A C/C tensile/compression test at 1700 °C illustrates successful use digital speckle pattern technology evaluate mechanical properti...

The motivation for the present study stems from the importance of delamination buckling as a viable mode of failure in laminated composite plates. This part of the study focuses on the prediction of the buckling loads and modes of unilaterally constrained rectangular plates. The laminated plates were modeled along the lines of classical lamination plate theory. Due to the out-of-plane thickness...

Software Defined Networks (SDN) have been proposed for use in applications of the Internet of Things (IoT), termed as software-defined IoT (SD-IoT) network, because of the popularity and capability of mobile devices being used for networking in relatively large areas. However, a single controller in SDN has a limited request-processing capability, so a distributed control plane with multiple ph...

Rotation of an inclined surface on which Helix is creeping straight upward, such that the axis of the animal is turned at a right angle to its previous position, but in the same plane, leads to negatively geotropic orientation after a measurable latent period or reaction time. The duration of the latent period is a function of the slope of the surface. The magnitude of the standard deviation of...

Fatigue life estimation is one of the most important design considerations in mechanical parts which are subjected to alternating loads. When loads act along several axes, multiaxial fatigue approach should be used to obtain more accurate results than uniaxial fatigue method. In this paper stress analysis of the steel shaft of a high speed microgenerator rotor with 47750 rpm and 100kW is carrie...
